Evaluation of Seattle’s Sweetened Beverage Tax

Impact of the Tax on Norms and Attitudes: The Evaluation of Seattle’s Sweetened Beverage Tax

August 2021

The University of Washington conducted a survey on Seattle’s 1.75 cent per ounce tax on sweetened beverages and found that people felt the tax was regressive and hurt neighborhood businesses in Seattle.

Key findings include:

76%

of people in Seattle believe that the burden of the tax falls heavier on working class communities and communities of color.

Support for the tax has fallen over time. Support for the tax declined from 60.4% in Oct.-Dec. 2017, just before the tax was imposed in January 2018, to 57.8% in Sept.-Nov. 2019.

There was a statistically significant increase of 11 percentage points of lower-income people surveyed who said they would shop outside of Seattle to purchase their beverages because of the tax.

The amount of those surveyed who believed the beverage tax would harm small businesses jumped 17 percentage points among the higher-income population.

Advocates of the tax sold it as a means to reduce consumption; however, this survey proves there is little to no evidence that the tax reduces consumption. Specifically:

  • Only 21% of residents reported that they consumed less sugar sweetened beverages because of the tax.

  • As part of the survey, researchers compared areas outside of Seattle (“Comparison Areas”) which saw a greater decrease in sugary drink consumption than Seattle which had the tax.

A 2020 study by the University of Washington and the Seattle’s Children’s Research Institute found:

  • The rate of soda consumption among children in Seattle was about the same as it was for children outside of the tax zone. The tax had no effect on the calories children in Seattle got from beverages judging from this comparison.

It’s clear: A beverage tax is not the answer.
