Sugary drink tax

Soda pop taxes are used in some jurisdictions to decrease consumption.

A sugary drink tax, soda tax, or sweetened beverage tax (SBT) is a tax or surcharge (food-related fiscal policy) designed to reduce consumption of drinks with added sugar. Drinks covered under a soda tax often include carbonated soft drinks, sports drinks and energy drinks. This policy intervention is an effort to decrease obesity and the health impacts related to being overweight, however the medical evidence supporting the benefits of a sugar tax on health is of very low certainty. The tax is a matter of public debate in many countries and beverage producers like Coca-Cola or Dr Pepper often oppose it. Advocates such as national medical associations and the World Health Organization promote the tax as an example of Pigovian taxation, aimed to discourage unhealthy diets and offset the growing economic costs of obesity.

Design

Tax design approaches include direct taxes on the product and indirect taxes. Indirect taxes include import/export taxes on sugar or other ingredients before it has been processed and local/regional.international taxes. Sales tax (indirect tax) is paid by the person consuming the item at the time of purchase and collected by the government from the seller. VAT (value added tax) is the most common type of tax and is also added on at the time of purchase, at an amount that is dependent on the value paid for the item. The amount of both VAT and sales tax are directly proportional to the amount of money paid for an item and do not consider the volume of food or drink. For this reason, a large (bulk) item would have less tax compared to a smaller cheaper item (i.e., there is less tax impact on larger packages of a food item).

Most taxes on sugar-sweetened beverages (SSBs) are set volumetrically (i.e., with a constant rate per unit volume), and that "only three SSB taxes worldwide are proportional to sugar content." The study argued that such volumetric taxes "are poorly targeted to the actual health harms from SSBs," and suggested taxing the amount of sugar in beverages, rather than the volume of liquid accompanying the sugar. A design change such as this has been proposed to "boost a SSB tax's health benefits and overall economic gains by roughly 30%."

Increased taxes on sweetened products have been suggested to promote companies to re-formulate their product in order to keep consumer costs affordable by decreasing use of the taxed ingredient (i.e., sugar) in their product. Government revenues from these taxes sometimes are put towards improving public health services, however this is not always the case.

Arguments against the sugary drinks tax

• The criteria on what drinks are taxed may not include equally bad substitutes like fruit juice, energy-dense snacks and biscuits.
• The tax is regressive since consumers on lower incomes will be more negatively impacted by higher prices than consumers on higher incomes. This regressive effect of the sugary drinks tax can be counteracted if the collected tax revenue is used to subsidize healthier foods.
• Cross-border shopping can also be an easy way out for consumers to not pay the tax as they will buy sugary drinks from areas where they are not taxed.

Health concerns related to excess sugar in the diet

Type 2 diabetes is a growing health concern in many developed and developing countries around the world, with 1.6 million deaths directly due to this disease in 2015 alone. Unlike sugar from food, the sugar from drinks enters the body so quickly that it can overload the pancreas and the liver, leading to diabetes and heart disease over time. A 2010 study said that consuming one to two sugary drinks a day increases your risk of developing diabetes by 26%.

Heart disease is responsible for 31% of all global deaths and although one sugary drink has minimal effects on the heart, consuming sugary drinks daily are associated with long term consequences. A study found that men, for every added serving per day of sugar-sweetened beverages, each serving was associated with a 19% increased risk of developing heart disease. Another study also found increased risks for heart disease in women who drank sugary drinks daily.

Obesity is also a global public and health policy concern, with the percentage of overweight and obese people in many developed and middle income countries rising rapidly. Consumption of added sugar in sugar-sweetened beverages has been positively correlated with high calorie intake, and through it, with excess weight and obesity. The addition of one sugar-sweetened beverage per day to the normal US diet can amount to 15 pounds of weight gain over the course of 1 year. Added sugar is a common feature of many processed and convenience foods such as breakfast cereals, chocolate, ice cream, cookies, yogurts and drinks produced by retailers. The ubiquity of sugar-sweetened beverages and their appeal to younger consumers has made their consumption a subject of particular concern by public health professionals. In both the United States and the United Kingdom, sugar sweetened drinks are the top calorie source in teenager's diets.

A French study published in 2019 on the British Medical Journal also enlighted a possible link between the consumption of sugary drinks (beverages containing more than a 5% of sugar) and a higher or increased risk of developing cancer. Even if the researchers were unable to proof a clear causality between the two factors, they stated that their results can be taken as a confirm that "reducing the amount of sugar in our diet is extremely important."

Dental caries, also known as tooth decay or dental cavities, is the most common noncommunicable disease worldwide. Sugary drink taxes have been discussed as a potential means to reduce the health and economic burden of dental caries.

Comparison to tobacco taxes

Proponents of soda taxes cite the success of tobacco taxes worldwide when explaining why they think a soda tax will work to lower soda consumption. Where the main concern with tobacco is cancer, the main concerns with soda are diabetes and obesity. The tactics used to oppose soda taxes by soda companies mimic those of tobacco companies, including funding research that downplays the health risks of its products.

Impact

Revenue

The U.S. Department of Health and Human Services reports that a national targeted tax on sugar in soda could generate $14.9 billion in the first year alone. The Congressional Budget Office (CBO) estimates that a nation-wide three-cent-per-ounce tax would generate over $24 billion over four years. Some tax measures call for using the revenue collected to pay for relevant health needs: improving diet, increasing physical activity, obesity prevention, nutrition education, advancing healthcare reform, etc. Another area to which the revenue raised by a soda tax might go, as suggested by Mike Rayner of the United Kingdom, is to subsidize healthier foods like fruits and vegetables.

Consumption

According to a 2019 review of research on sugar drink taxes, the taxes successfully reduced consumption of sugar drinks and reduced adverse health consequences.

In general, the theory of supply and demand predicts that the effect of taxes is to raise the consumer price of a good, and lower the quantity consumed. Whether the sugary drinks tax is imposed on the seller or consumer, in both cases the tax burden is shared between both.

Several studies have shown this effect in practice:

• A 10% tax in Mexico enacted in January 2014 reduced consumption by 12% after one year, said one study that had not yet been peer-reviewed.
• Various studies of the tax of one cent per ounce in Berkeley California have reported consumption has dropped between 9.6% and 52%, depending on the time period examined and the methods used.
• A study (which has yet to be peer-reviewed) of the 1.5-cents-per-ounce tax in Philadelphia found actual sales of the affected beverages (which included diet beverages) dropped 46% in the city itself, but when accounting for people traveling to neighboring cities without a tax, overall purchases of the affected beverages dropped 20%.

The way that the tax burden is divided upon the consumer and seller depends on the price elasticity for sugary drinks. The tax burden will fall more on sellers when the price elasticity of demand is greater than the price elasticity of supply while on buyers when the price elasticity of supply is greater than the price elasticity of demand. The price elasticity for sugary drinks is different from country to country. For instance, the price elasticity of demand for the sugary drink was found to be -1.37 in Chile while -1.16 in Mexico. Hence if both of those results were realistic and the price elasticity of supply would be the same for both, the tax burden on consumers would be higher in Mexico than in Chile.

A 2019 National Bureau of Economic Research paper concluded that sugar drink taxes were "welfare enhancing, and indeed that the optimal nationwide SSB tax rate may be higher than the one cent per ounce rate most commonly used in U.S. cities." A 2019 study in the Quarterly Journal of Economics estimated that the optimal sugar drink tax on the federal level in the U.S. would be between 1 and 2.1 cents per ounce, whereas the optimal tax on the city-level was 60% lower than that due to cross-border shopping.

Externalities as a rationale for taxation

The purchase of sugary drinks has a significant negative externalities when over-consumption causes diseases like obesity and type 2 diabetes. Depending on the national health care system, a significant portion of these costs are paid by taxpayers or insurance rate-payers; lost productivity costs are paid to some degree by employers.

Society as a whole could be worse off if these costs are calculated to be greater than the benefit to the consumers of soda.

A Pigovian tax like a sugary drinks tax, factors these externalities into the price of the beverage. To some degree, this causes people who over-consume soda to pay for health care costs they are causing, which proponents argue is more fair. In theory, this tax could be set at such a level that reduces consumption until the collective private benefit balances the collective costs of poorer health, though this could be accomplished at a lower tax level by using the tax revenue to create childhood nutrition programs or obesity-prevention programs. This would lessen the tax burden on people who consume soda moderately enough not to cause health problems.

Countries

A map of countries with nation-wide sugary drink taxes

Australia

The Australian Beverages Council announced in June 2018 that the industry would cut sugar content by 10% by 2020, and by another 10% by 2025. This was seen as an attempt to stave off a sugar tax. There were no plans to reduce the sugar content in the high sugar drinks. The plan is primarily to increase consumption of low-sugar or no-sugar drinks. Sales of Coca-Cola Amatil's fizzy drinks have fallen 8.1% by volume from 2016 to 2018. The Australian Medical Association continued to press for a sugar tax.

Bahrain

Tax since 2017.

Brunei

US$ 0.29/liter tax since April 2017.

Chile

In 2014, a measure was passed to increase tax on sugary drinks, and reduce tax on low-sugar drinks. The tax rate was increased from 13% to 18%, for drinks containing 6.25g added sugar per 100ml. In contrast, the tax rate on drinks with less added sugar was decreased to 10%. This has led to a 21.6% decrease in the consumption of sugary drinks.

Colombia

A 2016 proposal for a 20% sugary drink tax, campaigned by Educar Consumidores, was turned down by the Colombian legislature despite popular support for it. Soda is often less expensive than bottled water in Colombia.

Canada

In 2020, the Province of British Columbia stopped exempting soda beverages from a 7% provincial sales tax for grocery items. Still fruit juices and non-sweetened carbonated beverages are still exempted from the tax. The measure was introduced based on health recommendations to address youth obesity.

In May of 2021, the Province of Newfoundland and Labrador announced a 20 cent per litre tax for sugar sweetened beverages. This tax will be implemented on April 1 2022.

Denmark

Denmark instituted a soft drink tax in the 1930s (it amounted to 1.64 Danish krone per liter), but announced in 2013 that they were going to abolish it along with an equally unpopular fat tax, with the goal of creating jobs and helping the local economy. Critics claimed that the taxes were notably ineffective; to avoid the fat and sugar taxes, local retailers had complained that Danes simply went to Sweden and Germany, where prices were lower to buy butter, ice cream and soda. Denmark repealed the fat tax in January 2013 and repealed the tax on soft drinks in 2014.

Finland

Finland introduced a sugar tax in 1940.

France

France first introduced a targeted tax on nonalcoholic sugary drinks at a national level in 2012. The tax, which is 0.0716 euro per liter, applies to both regular and diet soft drinks, flavored mineral water, and fruit juices with added sugar, but does not apply to mineral water and 100% fruit juices (i.e., those with no added sugars). Following introduction, soft drinks were estimated to be up to 3.5% more expensive.

A 2019 article published in the journal PLOS One estimated the price and consumption effects of the tax, using a difference-in-difference methodology. The study concluded: "We find that the tax is transmitted to the prices of taxed drinks, with full transmission for soft drinks and partial transmission for fruit juices. The evidence on purchase responses is mixed and less robust, indicating at most a very small reduction in soft drink purchases (about half a litre per capita per year), an impact which would be consistent with the low tax rate. We find suggestive evidence of a larger response by the sub-sample of heavy purchasers. Fruit juices and water do not seem to have been affected by the tax."

Hungary

Hungary's tax, which came into effect in September 2011, is a 4 per cent tax on foods and drinks that contain large quantities of sugar and salt, such as soft drinks, confectionery, salty snacks, condiments, and fruit jams. In 2016, the tax has resulted in a 22% reduction in energy drink consumption and 19% of people reduced their intake of sugary soft drinks.

India

40% tax on sugary soda from 1 July 2017.

Ireland

Soda tax introduced on 1 May 2018. The tax will see 30 cent per litre added to the price of popular sweetened drinks containing more than 8g of sugar per 100ml.

Malaysia

Malaysia has a sugary drink tax implemented 1 July 2019.

Mexico

In September 2013, Mexico's president Enrique Peña Nieto, on his fiscal bill package, proposed a 10% tax on all soft drinks, especially carbonated drinks, with the intention of reducing the number of patients with diabetes and other cardiovascular diseases in Mexico, which has one of the world's highest rates of obesity. According to Mexican government data, in 2011, the treatment for each patient with diabetes cost the Mexican public health care system (the largest of Latin America) around US$708 per year, with a total cost of 778,427,475 USD in 2010, and with each patient paying only 30 MXN (around US$2.31).

In September 2013, soda companies launched a media campaign to discourage the Mexican Chamber of Deputies and Senate from approving the 10% soda tax. They argued that such measure would not help reduce the obesity in Mexico and would leave hundreds of Mexicans working in the sugar cane industry jobless. They also publicly accused New York City Mayor Michael Bloomberg of orchestrating the controversial bill from overseas. In late October 2013, the Mexican Senate approved a 1 MXN per litre tax (around US$0.08) on sodas, along with a 5% tax on junk food.

Research has shown that Mexico's sugary drinks tax reduced soft drink consumption. According to a 2016 study published in BMJ, annual sales of sodas in Mexico declined 6% in 2014 after the introduction of the soda tax. Monthly sales figures for December 2014 were down 12% on the previous two years. Households with the fewest resources had an average reduction in purchases of 9% in 2014, increasing to 17% by December. Furthermore, purchases of water and non-taxed beverages increased by about 4% on average. Whether the imposition of the tax and the resulting 6% decline in sales of soft drinks will have any measurable impact on long-term obesity or diabetes trends in Mexico has yet to be determined. The authors of the study urged the Mexican authorities to double the tax to further reduce consumption.

A 2016 study published in PLoS Medicine suggested that a 10% excise tax on soda "could prevent 189,300 new cases of Type 2 diabetes, 20,400 strokes and heart attacks, and 18,900 deaths among adults 35 to 94 years old" over a ten-year period. The study also included that "the reductions in diabetes alone could yield savings in projected healthcare costs of $983 million."

A 2017 study in the Journal of Nutrition found a 6.3% reduction in soft drink consumption, with the greatest reductions "among lower-income households, residents living in urban areas, and households with children. We also found a 16.2% increase in water purchases that was higher in low- and middle-income households, in urban areas, and among households with adults only."

Norway

Norway has had a generalized sugar tax measure on refined sugar products since 1922, introduced to boost state income rather than reducing sugar consumption. Non-alcoholic beverages have since been separated from the general tax, and in 2017, the tax for sugary drinks was set to 3.34 kroner per litre.

In January 2018, the Norwegian government increased the sugar tax level by 83% for general sugar-containing ready-to-eat products, and 42% for beverages. The sugar tax per litre was bumped up to 4.75 kroner, and applies to beverages which are either naturally or artificially sweetened.

The 42 % tax increase on non-alcoholic beverages was attacked by Norwegian retailers and received much media attention. The increase was claimed to encourage even more traffic to the Swedish border shops, as Sweden does not have tax on non-alcoholic beverages. The tax increase was rolled back to 2017-level in 2020.

As a result of a budget settlement, the tax on non-alcoholic beverages was further reduced by 48.1 % to 1.82 kroner per litre, effective January 2021.

Oman

Tax since June 2019.

Peru

25% tax since May 2018.

Qatar

Tax since January 2019.

Philippines

In the taxation reform law dubbed as the Tax Reform for Acceleration and Inclusion Law (TRAIN) signed by Philippine President Rodrigo Duterte in December 2017. It includes taxation on sugar-sweetened drinks which will be implemented the following year, as an effort to increase revenue and to fight obesity. Drinks with caloric and non-caloric sweeteners will be taxed ₱6.00 per liter, while those using high-fructose corn syrup, a cheap sugar substitute, will be taxed at ₱12 per liter.

Exempted from the sugar tax are all kinds of milk, whether powdered or in liquid form, ground and 3-in-1 coffee packs, and 100-percent natural fruit and vegetable juices, meal replacements and medically indicated drinks, as well as beverages sweetened with stevia or coco sugar. These drinks, especially 3-in-1 coffee drinks which are popular especially among lower-income families, are to be taxed as initially proposed by the House of Representatives version of the bill, but were exempted in the Senate version.

Poland

Tax since January 2021.

Portugal

Portugal introduced a sugary drink tax in 2017. It also has a tax on foods with high sodium.

Saudi Arabia

Saudi Arabia has a 50% sugar tax only on soft and energy drinks since 10 June 2017, and since 1 December 2019 the same tax percentage applies to all sugary drinks.

Singapore

During the National Day Rally 2017, Prime Minister Lee Hsien Loong spoke at length on the importance of fighting diabetes. He said, "If you drink soft drinks every day, you are overloading your system with sugar, and significantly increasing your risk of diabetes. Our children are most at risk because soft drinks are part of their lifestyle."

On 4 December 2018, the Ministry of Health began a consultation exercise to seek public's feedback on four proposed measures to fight diabetes including a ban on high-sugar packet drinks and implementation of a sugar tax. On 10 October 2019, the Ministry of Health chose to ban advertisements of drinks with high sugar content; making Singapore the first country in the world to do so, as well as introduce color-coded labels. This comes after a public consultation favored these two options out of four. The labels will indicate drinks as "healthy", "neutral", "unhealthy" and take into account the amount of sugar and saturated fat contained in drinks, among other factors. They will be compulsory for "unhealthy" drinks and optional for "healthy" ones, covering instant drinks, soft drinks, juices, cultured milk and yogurt drinks in bottles, cans and packs. These measures will take effect sometime in 2020.

South Africa

South Africa proposed a sugar-sweetened beverages tax in the 2016 South African national government budget. South Africa introduced a sugar tax on 1 April 2018. The levy was fixed at 2.1 cents per gram of sugar, for each gram above 4g per 100ml of sweetened beverage. The levy excludes fruit juices, despite health professionals warning that fruit juice is as bad for a person as highly sugary drinks.

Thailand

Sugar tariffs since Oct 2017.

United Arab Emirates

In October 2017, the United Arab Emirates introduced a 50% tax on soft drinks and a 100% tax on energy drinks, to curb unhealthy consumption of sugary drinks that can lead to diabetes; it also added a 100% tax on cigarettes. From 1 January 2020, the UAE would impose a tax on all products which contains sugar or artificial sweeteners.

United Kingdom

In the 2016 United Kingdom budget, the UK Government announced the introduction of a sugar tax, officially named the "Soft Drinks Industry Levy". The tax came into effect on 6 April 2018. Beverage manufacturers are taxed according to the volume of sugar-sweetened beverages they produce or import. The tax is imposed at the point of production or importation, in two bands. Drinks with total sugar content above 5g per 100 millilitres are taxed at 18p per litre and drinks above 8g per 100 millilitres at 24p per litre. The measure was estimated to generate an additional £1 billion a year in tax revenue which would be spent on funding for sport in UK schools. Despite not being part of the United Kingdom the British Soft Drinks Industry Levy came into force on the Isle of Man on 1 April 2019 because of the Common Purse Agreement.

It was proposed that pure fruit juices, milk-based drinks and the smallest producers would not be taxed. For other beverages there was an expectation that some manufacturers would reduce sugar content in order to avoid the taxation. Indeed, manufacturer A.G. Barr significantly cut sugar content in their primary product Irn-Bru in advance of the tax.

Notable research on effect of excess sugar in modern diets in the United Kingdom includes the work of Professor John Yudkin with his book called, "Pure, White and Deadly: The Problem of Sugar" first published in 1972. With regard to a proposed tax on sugar-sweetened beverages, a study published in the British Medical Journal on 31 October 2013, postulated that a 20% tax on sugar-sweetened beverages would reduce obesity in the United Kingdom rates by about 1.3%, and concluded that taxing sugar-sweetened beverages was "a promising population measure to target population obesity, particularly among younger adults."

Estimates of the revenue raised were reduced to £240 million per annum in 2019. It helped to boost sales, rather than dampening performance, according to Britvic’s 2018 Soft Drinks Review. In April 2018 only 8.4% of the market was liable to the levy because drinks were reformulated.

Criticism

The tax has been criticised on several grounds, including its likely efficacy and its narrow base. UK Member of Parliament Will Quince called it "patronising, regressive and the nanny state at its worst." In addition a study by the University of Glasgow, which sampled 132,000 adults, found that focusing on sugar in isolation misleads consumers as reducing fat intake is also crucial to reducing obesity.

From an opposing standpoint, Professor Robert Lustig of the University of California, San Francisco School of Medicine, has argued that the UK tax measure may not go far enough and that, "juice should be taxed the same way as soda because from a metabolic standpoint juice is the same as soda." Campaigners have since called for the soft drinks tax to be extended to include confectionery and sweets to help tackle childhood obesity.

United States

The United States does not have a nationwide soda tax, but a few of its cities have passed their own tax and the U.S. has seen a growing debate around taxing soda in various cities, states and even in Congress in recent years. A few states impose excise taxes on bottled soft drinks or on wholesalers, manufacturers, or distributors of soft drinks.

Supermarket chilled beverage selection

American localities with a soda tax

Philadelphia and Berkeley are the first two cities to pass a tax on sugary drinks in the U.S. Berkeley's tax of 1 cent/oz of sugary drink has seen a decline in soda consumption by more than 20 percent. Philadelphia's tax of 1.5 cents/oz took effect on 1 January 2017.

Berkeley, California

The Measure D soda tax was approved by 76% of Berkeley voters on 4 November 2014, and took effect on 1 January 2015 as the first such tax in the United States. The measure imposes a tax of one cent per ounce on the distributors of specified sugar-sweetened beverages such as soda, sports drinks, energy drinks, and sweetened ice teas but excluding milk-based beverages, meal replacement drink, diet sodas, fruit juice, and alcohol. The revenue generated will enter the general fund of the City of Berkeley. A similar measure in neighboring San Francisco received 54% of the vote, but fell short of the supermajority required to pass. In August 2015, researchers found that average prices for beverages covered under the law rose by less than half of the tax amount. For Coke and Pepsi, 22 percent of the tax was passed on to consumers, with the balance paid by vendors. UC Berkeley researchers found a higher pass-through rate for the tax: 47% of the tax was passed-through to higher prices of sugar-sweetened beverages overall with 69% being passed-through to higher soda prices. In August 2016, a UC Berkeley study (relying on self-reporting) showed a 21% drop in the drinking of soda and sugary beverages in low-income Berkeley neighborhoods after a few months.

A study from 2016 compared the changing intake of sugar sweetened beverages and water in Berkeley versus San Francisco and Oakland (which did not have a sugary drink tax passed) before and after Berkeley passed its sugary drink tax. This analysis showed a 26% decrease of soda consumption in Berkeley and 10% increase in San Francisco and Oakland while water intake increased by 63% in Berkeley and 19% in the two neighboring cities. A 2017 before and after study has concluded that one year after the tax was introduced in Berkeley, sugary drink sales decreased by 9.6% when compared to a scenario where the tax was not in place. This same study was also able to show that overall consumer spending did not increase, contradicting the argument of opponents of the Sugary Drink Tax. Another 2017 study results were that purchases of healthier drinks went up and sales of sugary drinks went down, without overall grocery bills increasing or the local food sector losing money.

A 2019 study relying on self-reporting found a 53% drop in consumption in low-income neighborhoods after three years.

Philadelphia, Pennsylvania

Democratic Philadelphia mayor Jim Kenney proposed a citywide soda tax that would raise the price of soda at three cents per ounce. At the time, it was the biggest soda tax proposal in the United States. Kenney promoted using tax revenue to fund universal pre-K, jobs, and development projects, which he predicted would raise $400 million over five years, all the while reducing sugar intake by decreasing the demand for sugary beverages. Kenney's soda tax proposal was brought to the national spotlight and divided key members of the Democratic Party. Presidential hopeful Bernie Sanders argued in an op-ed that the tax would hurt the poor. His opponent, Hillary Clinton, on the other hand, said that she was "very supportive" of the idea. The American Beverage Association (ABA), funded by soda companies and distributors, ran local television, radio, and newspaper advertisements against the idea, claiming that the tax would disproportionately hurt the poor. The ABA spent $10.6 million in 2016 in its effort against the tax. The American Medical Association, American Heart Association, and other medical and public health groups support the tax.

The Philadelphia City Council approved a 1.5-cents-per-ounce tax on 16 June 2016. As part of the compromise legislation that passed, the tax is also imposed on artificially sweetened beverages, such as diet soda. The law became effective on 1 January 2017. It was reported after two months of the tax that Philadelphia supermarkets and beverage distributors are planning layoffs because sugary beverage sales are down between 30 and 50 percent.

After the tax took effect, Kenney said retailers' price gouging blamed on the tax and charging the tax on items not subject to it was "wrong" and "misleading". In February 2017, soda manufacturers and retailers announced sales declines of 30-50% in Philadelphia and announced job cuts and layoffs. Kenny characterized the layoffs as evidence of greed among manufacturers. In the first four months of the soda tax $25.6 million was collected, which is lower than predicted. The revenue is intended to pay for a pre-K program (49% of tax revenue), government employee benefits and city programs (20%), and rebuilding city parks and recreation centers. A recent study from 2017 found that Philadelphia's tax has decreased sugary beverage consumption in impoverished youth by 1.3 drinks/week. Langellier et al. also found that when paired with the pre-K program, attendance increases significantly, a finding that is likely to have longer term positive effects than a sugary drink tax alone.

In March 2017, Pepsi laid off between 80 and 100 employees at two distribution plants in Philadelphia and one plant in nearby Wilmington, Delaware. The company blamed the layoffs on the tax, an assertion rejected by the city government.

In September 2016, the American Beverage Association, Philadelphia business owners, and other plaintiffs filed a lawsuit against the soda tax, alleging that the tax violated the "Tax Uniformity Clause" of the state constitution. The legal challenge was dismissed by the Court of Common Pleas in December 2016, and in June 2017 the Commonwealth Court of Pennsylvania (in a 5-2 decision) affirmed that ruling. The ABA appealed the decision to the Pennsylvania Supreme Court but on 18 July 2018, the court upheld the tax in a 4-2 decision.

A 2019 study (which has yet to be peer-reviewed) of the 1.5-cents-per-ounce tax in Philadelphia found actual sales of the affected beverages (which included diet beverages) dropped 46% in the city itself, but when accounting for people traveling to neighboring cities without a tax, overall purchases of the affected beverages dropped 20%.

San Francisco, California

A one-cent-per-ounce soda tax (Prop V) passed with over 61% of the vote on 8 November 2016 and applies to distributors of sugary beverages on 1 January 2018. Exemptions for the tax include infant formulas, milk products, supplements, drinks used for medical reasons, and 100% fruit and vegetable juices. The soda industry spent almost $20 million in its unsuccessful push to defeat the soda tax initiative, a record-breaking amount for a San Francisco ballot initiative.

In 2014, the first referendum on a soda tax, Proposition E, was voted down by San Francisco; the 2014 referendum received the support of 55 percent of voters, short of the two-thirds required for a referendum directing money to a specific item (the referendum proposed directing the revenue raised to children's physical education and nutrition programs, and in San Francisco such earmarking requires a two-thirds vote to pass). In that referendum campaign, the soda industry spent about $10 million in opposition to the proposed tax.

Oakland, California

A one-cent-per-ounce soda tax (Measure HH) passed with over 60% of the vote on 8 November 2016. The tax went into effect on 1 July 2017.

Albany, California

A one-cent-per-ounce soda tax (Prop O1) passed with over 70% of the vote on 8 November 2016. The tax went into effect on 1 April 2017

Boulder, Colorado

A two-cents-per-ounce soda tax (Measure 2H) passed with 54% of the vote on 8 November 2016. The tax took effect on 1 July 2017, and revenue will be spent on health promotion, general wellness programs and chronic disease prevention that improve health equity, and other health programs especially for residents with low income and those most affected by chronic disease linked to sugary drink consumption. The University of Colorado, Boulder, campus was granted a one-year exemption from the tax as school officials survey what types of drinks students wish to have. The University was not aware it would be involved in the soda tax, and would have to pay an estimated additional $1 million a year to purchase sugary drinks.

Cook County, Illinois

A one-cent-per-ounce soda tax passed on 10 November 2016, by a 9–8 vote, with Cook County Board of Commissioners President Toni Preckwinkle breaking the 8–8 tie. Cook County includes Chicago and has a population of nearly 5.2 million. This was the most populous jurisdiction with a soda tax in the U.S. The campaign to introduce the tax was heavily funded by Mike Bloomberg.

On 30 June 2017, a Cook County judge granted a temporary restraining order filed by the Illinois Retail Merchants Association and several Cook County-based grocers that prohibited the tax from being put into effect until at least 12 July. The tax eventually went into effect on 2 August. Due to a conflict with the Supplemental Nutrition Assistance Program, this soda tax did not apply to any soda purchases made with food stamps, which were used by over 870,000 people. Controversially, the tax affected diet drinks but not sugar-packed fruit juices.

On 10 October 2017, the Board of Commissioners voted to repeal the tax in a 15–1 vote. The tax stayed in effect up until 1 December. The tax was highly unpopular and seen mainly as an attempt to plug the county's $1.8 billion budget deficit, rather than a public health measure.

Navajo Nation

In addition to the general sales tax (6 percent as of July 1, 2018) the Navajo Nation levies a special Junk Food Tax on applicable junk food items. The Junk Food Tax rate is 2 percent and applies to sales of sweetened beverages

Portland, Oregon

The Coalition for Healthy Kids and Education is currently campaigning to get a soda tax on the May 2018 ballot. Their aim is to implement a 1.15 cents per ounce tax on sugary drinks. There are 18,000 signatures required by 15 December 2017 in order for the tax to be voted on in May.

Seattle, Washington

On 5 June 2017, Seattle's City Council voted 7–1 to pass a 1.75 cents per ounce tax on sugary drinks, including soda and some fruit drinks; the tax does not include diet soda drinks and it started on 1 January 2018. The $15 million Seattle assumes will be collected from the tax will be used for programs that give access to more fruits and vegetables for low-income families, adding education programs and studying the tax on how it impacts behavior. Seattle collected over $17 million in the first nine months of the tax and the price increase has mostly passed on to the consumers.

In 2018, Washington state voters approved Initiative 1634 which bans new taxes on grocery items such as sugary drinks, blocking other Washington cities from adding a sugary drink tax. Funding for the "Yes on 1634" campaign included over $20 million from major beverage producers. Both proponents and opponents of the initiative made reference to Seattle's sugary drink tax.

St Helena

In March 2014, the government of the island of St Helena, a British Overseas Territory in the South Atlantic, announced that it would be introducing an additional import duty of 75 pence per litre on sugar-sweetened carbonated drinks with more than 15 grams of sugar per litre. The measure was introduced in May 2014 as part of a number of measures to tackle obesity on the island and the resulting high incidence of type 2 diabetes.

Tonga

Tonga has a soda tax.

Scientific studies

Coca-Cola has been under fire since 2015 when emails revealed that funding for scientific studies sought to influence research to be more favorable to soda. Research funded by soda companies are 34 times more likely to find soda has no significant health impacts on obesity or diabetes.

Taxing soda can lead to a reduction in overall consumption, according to a scientific study published in the Archives of Internal Medicine in March 2010. The study found that a 10 percent tax on soda led to a 7 percent reduction in calories from soft drinks. These researchers believe that an 18 percent tax on these foods could cut daily intake by 56 calories per person, resulting in a weight loss of 5 pounds (2 kg) per person per year. The study followed 5,115 young adults ages 18 to 30 from 1985 to 2006.

A 2010 study published in the medical journal Health Affairs found that if taxes were about 18 cents on the dollar, they would make a significant difference in consumption.

Research from Duke University and the National University of Singapore released in December 2010 tested larger taxes and determined that a 20 percent and 40 percent taxes on sugar-sweetened beverages would largely not affect calorie intake because people switch to untaxed, but equally caloric, beverages. Kelly Brownell, a proponent of soda taxes, reacted by stating that "[t]he fact is that nobody has been able to see how people will really respond under these conditions." Similarly, a 2010 study concluded that while people would drink less soda as a result of a soda tax, they would also compensate for this reduction by switching to other high-calorie beverages. In response to these arguments, the American Public Health Association released a statement in 2012 in which they argued that "Even if individuals switch to 100% juice or chocolate milk, this would be an improvement, as those beverages contribute some nutrients to the diet."

A 2011 study in the journal Preventive Medicine concluded that "a modest tax on sugar-sweetened beverages could both raise significant revenues and improve public health by reducing obesity". It has been used by the Rudd Center for Food Policy and Obesity at Yale to estimate revenue from a soda tax, depending on the state, year and tax rate.

A 2012 study by Y. Claire Wang, also in the journal Health Affairs, estimates that a penny per ounce tax on sugared beverages could prevent 2.4 million cases of diabetes per year, 8,000 strokes, and 26,000 premature deaths over 10 years.

In 2012, just before the city of Richmond began voting on a soda tax, a study was presented at a conference held by the American Public Health Association regarding the potential effects of such a tax in California. The study concluded that, given that soda's price elasticity is such that taxing it would reduce consumption by 10–20 percent, that this reduction "...is projected to reduce diabetes incidence by 2.9–5.6% and CHD by 0.6–1.2%."

A 2013 study in the American Journal of Agricultural Economics concluded that a 0.5-cent-per-ounce tax on soft drinks would reduce consumption, but "increase sodium and fat intakes as a result of product substitution," in line with the Duke University study mentioned above.

A 2014 study published in the American Journal of Public Health concluded that Sugar-Sweetened Beverages (SSBs) don't have a negative impact on employment. Even though job losses in the taxed industry occurred, they were offset by new employment in other sectors of the economy.

A 2016 modelling study estimated that a 20% tax on SSBs would decrease the consumption of SSBs in Australia by 12.6%. The tax could decline the prevalence of obesity in the Australian population, which could lead to gains in health-adjusted life years. The results showed an increase of 7.6 days in full health for a 20-24-year-old male and a 3.7 day increase in longevity for their female peers.

Between 2016 and 2020, economists from the University of Iowa, Cornell University, and Mathematica, a policy research firm, conducted a multiyear study of local sweetened-beverage taxes in Philadelphia, Oakland, Seattle, and San Francisco. The study examined the taxes’ one-year impacts on purchases, consumption, tax pass-through rates, pricing, and product availability. It was the first to look at the impacts on Oakland's sugar-sweetened beverage tax and the first to look at impacts of the taxes on children's consumption in either Philadelphia or Oakland. The study found that almost a year after Philadelphia and Oakland implemented taxes on sweetened beverages, purchases of sweetened beverages declined, but evidence also suggests that some city residents shopped more outside of the cities. Consumption did not decline significantly overall in Philadelphia or Oakland, but there is more evidence of reduced consumption in Philadelphia, particularly among certain groups. Findings from the project have been published in peer-reviewed journals, such as the Journal of Policy Analysis and Management, Economics and Human Biology, the Journal of Health Economics, as well as in working papers hosted by the National Bureau of Economic Research and in Mathematica issue briefs.

Proposals

There have been a number of proposed taxes on sugary beverages, including:

• In 1914, U.S. President Woodrow Wilson proposed a special revenue tax on soft drinks, beer and patent medicine after the outbreak of World War I caused a decline in imports and a corresponding decline in credit created by import tariffs. This proposed taxation measure was not however linked to the anticipated health outcomes of reduced sugar sweetened beverage consumption.
• In 1994, one of the first instances where the idea of a targeted tax on sugar sweetened drinks with a link to anticipated beneficial health outcomes, was proposed by Kelly D. Brownell, Director of the Rudd Center for Food Policy and Obesity at Yale.
• In a 2009 "Perspective" piece in the New England Journal of Medicine, Kelly D. Brownell, Director of the Rudd Center for Food Policy and Obesity at Yale, and Thomas R. Frieden, Director of the U.S. Centers for Disease Control and Prevention, argue for taxing sugary beverages. The authors propose that sugary beverages may be the single largest cause of the obesity epidemic. They state that an excise tax of one cent per ounce would reduce consumption by more than 10%.
• Maryland and Virginia are two of 33 states that levy sales taxes on soda. Maryland taxes soda at a rate of 6%, while Virginia's rate is 1.5%. Virginia is also one of six states that impose a state excise tax on soda in addition to a sales tax.
• In 2009, the Obama Administration explored levying an excise tax on sweetened beverages as part of health care reform efforts, but the proposal was abandoned after heavy lobbying by the beverage industry.
• In 2010, New York State considered a soda tax, however opposition from the soda industry and economists made a strong antitax campaign, spending at least double of the tax supporters and the plan failed.
• In 2012, the City Council of Richmond, California placed the soda tax on the November 2012 ballot along with an advisory measure asking voters how they would like to spend the tax revenue. This proposal was rejected by the voters with 67% voting no and 33% voting yes.
• In the California State Legislature, soda tax proposals have been introduced several times, but have not passed. In 2013, California state senator Bill Monning proposed a soda tax, but the bill died in committee. In 2014, a 1-cent-per-ounce statewide soda tax was proposed in the legislature, but was defeated amid opposition by the California Beverage Association, a business lobbying group. In 2016, Assemblymen Richard Bloom and Jim Wood introduced a bill to create a "health impact fee" of 2-cent-per-ounce on sugary drinks, with the revenue collected from the tax to go toward programs for making drinking water safe, promoting oral health, and preventing obesity and diabetes. However, the proposal again faced strong opposition from industry groups, and the bill's proponents withdrew the proposal without a vote after it became clear that it lacked the votes to pass.
• In June 2013, the city of Telluride, Colorado proposed a penny-per-ounce soda tax; however, it was rejected in November, with 68% of voters voting against it.
• In July 2014, U.S. Representative Rosa DeLauro of Connecticut, proposed a national soda tax bill in the House of Representatives.
• In November 2014, voters in San Francisco and Berkeley, California voted on soda tax ballot measures. The measure was approved in Berkeley and received 55% of the vote in San Francisco, which was short of the needed 2/3 supermajority.
• In November 2016, Santa Fe began considering a tax on all sugar-sweetened beverages, including soda, sports drinks, and iced tea, to fund early childhood education. However, voters rejected the proposal in a May 2017 special election.

Public support

A 2016 poll by Morning Consult-Vox finds Americans split on their support of a soda tax. Attitudes seem to have shifted a lot since 2013 when a poll concluded that "respondents were opposed to government taxes on sugary drinks and candy by a more than 2-to-1 margin." In California, however, support for a tax has been high for a few years. According to a Field Poll conducted in 2012, "Nearly 3 out of 5 California voters would support a special fee on soft drinks to fight childhood obesity." Support for a soda tax in New York was higher when pollsters say the money will go towards health care. A Quinnipiac University poll released in April 2010 found that New Yorkers opposed a state tax on soda of one penny per ounce by a 35-point margin, but opposition dropped to a margin of one point when respondents were told the money would go towards health care. A Thompson Reuters poll released in the same month found that 51 percent of Americans opposed a soda tax, while 33 percent supported one.

Lobbying

Fighting the creation of soft drink taxes, the American Beverage Association, the largest U.S. trade organization for soft drink bottlers, has spent considerable money lobbying Congress. The Association's annual lobbying spending rose from about $391,000 to more than $690,000 from 2003 to 2008, and in the 2010 election cycle, its lobbying grew to $8.67 million. These funds helped to pay for 25 lobbyists at seven different lobbying firms.

An industry group called "Americans Against Food Taxes," backed by juice maker Welch's, soft drink maker PepsiCo Inc, the American Beverage Association, the Corn Refiners Association, McDonald's Corporation and Burger King Holdings Inc used national advertising and conducted lobbying to oppose these taxes. The group has characterized the soda tax as a regressive tax, which would unfairly burden the poor.

History

Protesters in 1919 call for an end to a soda tax.

Denmark began taxing soft drinks and juices in the 1930s. More recently, Finland reintroduced an earlier soft drink tax in 2011, while Hungary taxes sugary drinks as part of its 2011 public health product tax, which covers all food products with unhealthy levels of sugar. France introduced a targeted sugar tax on soft drinks in 2012. At a national level, similar measures have also been announced in Mexico in 2013 and in the United Kingdom in 2016. In November 2014, Berkeley, California was the first city in the U.S. to pass a targeted tax on sugary drinks.
