Beverage Syrup and Soft Drink Excise Taxes: Rates and Exemptions

Beverage syrup and soft drink excise taxes are local levies imposed by a small number of U.S. cities and by the state of Arkansas on the distribution of sweetened drinks and the concentrates used to make them. There is no federal soft drink excise tax. Rates in the cities generally fall between 1 and 2 cents per fluid ounce of finished beverage, and the tax is paid by distributors, not collected from customers at the register.1Tax Policy Center.

Where the Tax Applies

Seven cities currently impose a per-ounce excise tax on sugar-sweetened beverages: Berkeley, Oakland, San Francisco, and Albany in California; Philadelphia; Seattle; and Boulder. Arkansas is the only state with a dedicated soft drink excise tax. West Virginia had one for more than 70 years but repealed it effective July 1, 2024.1Tax Policy Center. How Do State and Local Soda Taxes Work

Outside those jurisdictions, a distributor or retailer has no soft drink excise tax obligation. Four states have gone further and passed preemption laws that block new local soda taxes: Arizona (2018), California (2018, expires 2031), Michigan (2017), and Washington (2018). California and Washington grandfather in the taxes their cities already had. Oregon’s broader ban on local sales taxes also blocks local beverage taxes.

What Products Are Covered

Two categories of product are taxable: finished sweetened beverages and the concentrated ingredients used to produce them.

Finished beverages include any non-alcoholic drink in a sealed container that contains a caloric sweetener such as sugar, high-fructose corn syrup, or honey. Regular sodas, sweetened iced teas, sports drinks, energy drinks, and fruit drinks that aren’t 100 percent juice all qualify. Carbonation isn’t the trigger — added sugar is. A flat sweet tea is taxed the same as a cola.

Syrups and powders make up the second category because they are the base for fountain drinks. A bag-in-box syrup shipped to a restaurant is taxable based on the volume of finished beverage it can produce. Dry mixes are treated the same way. The taxable event is the first distribution of these products within the taxing jurisdiction.

Diet and Zero-Calorie Drinks

Whether artificially sweetened drinks are taxable depends on the city. Most jurisdictions tax only drinks with caloric sweeteners. Berkeley, for example, exempts anything under 2 calories per ounce, which leaves out beverages sweetened with aspartame or stevia.1Tax Policy Center. How Do State and Local Soda Taxes Work

Philadelphia is the outlier. Its beverage tax reaches any drink that lists any sweetener as an ingredient, caloric or not. Diet sodas, zero-calorie energy drinks, and stevia- or sucralose-sweetened products are all taxable there. A distributor operating in more than one taxing city has to track which products are taxable in each one separately.

Common Exemptions

Several categories fall outside the tax in every jurisdiction that has enacted one, though the exact boundaries vary:

  • 100 percent fruit or vegetable juice that qualifies as such under federal labeling rules. A 50 percent juice blend sweetened to fill the rest does not qualify.
  • Dairy milk and milk alternatives such as soy or almond milk, provided they meet nutritional thresholds. Several jurisdictions follow the SSUTA definition, which excludes any drink with milk or a milk substitute as a primary ingredient.
  • Infant formula and products designed for managing specific medical conditions.
  • Alcoholic beverages, which are covered by separate alcohol excise regimes.

Distributors handling both taxable and exempt products need documentation supporting each exemption claimed — typically exemption certificates and records showing product composition. In an audit, the burden of proving the exemption sits with the distributor.

Who Pays and Who Registers

The tax obligation lands on the distributor, meaning the business that first sells or delivers a taxable beverage to a retailer within the taxing jurisdiction. The distributor calculates what’s owed based on volume distributed, files the return, and remits payment directly to the city or state revenue authority.1Tax Policy Center.

Distributors must register before distributing taxable products. In Philadelphia, registration is handled through the city’s online tax portal, and a registered distributor must provide itemized receipts showing the tax on every transaction with a dealer. If a retailer buys from a supplier that cannot register, the retailer may itself need to register as a “special dealer” and file the returns directly. A retailer who buys from an unregistered distributor may become personally liable for the tax, so verifying a supplier’s registration status matters if you operate a retail location in a taxing jurisdiction.

Rates by Jurisdiction

City rates fall within a narrow band per fluid ounce of finished drink:

  • 1 cent per ounce: Berkeley, Oakland, San Francisco, and Albany
  • 1.5 cents per ounce: Philadelphia
  • 1.75 cents per ounce: Seattle, with a reduced 1-cent rate for certified small manufacturers
  • 2 cents per ounce: Boulder

At those rates, a standard 12-ounce can carries 12 to 24 cents in excise tax depending on location. A 2-liter bottle (about 67.6 ounces) would owe roughly 68 cents in Berkeley or $1.35 in Boulder.1Tax Policy Center. How Do State and Local Soda Taxes Work

Arkansas uses a different structure. Bottled soft drinks are taxed at 20.6 cents per gallon and soft drink syrups at $1.26 per gallon. Powders and base products are taxed at 20.6 cents for each gallon of finished beverage they produce.

Calculating the Tax on Syrups and Powders

For cans and bottles, the math is direct: ounces distributed multiplied by the per-ounce rate. Syrups and powders take an extra step because the tax is based on the volume of finished drink the concentrate produces, not the volume of the concentrate itself.

The standard dilution ratio for fountain syrup is five parts carbonated water to one part syrup, so one gallon of syrup yields roughly six gallons of finished beverage. Most major brands use this 5-to-1 ratio for their bag-in-box products, though formulations vary. The taxing jurisdiction expects you to use the manufacturer’s specified yield.

Powdered mixes work the same way: determine how many fluid ounces of finished drink the powder produces according to the package directions, then apply the per-ounce rate to that total. Getting the yield wrong is where underpayment problems tend to start. If an auditor recalculates using the manufacturer’s specifications and comes up with more finished ounces than you reported, the difference becomes back taxes plus penalties.

Filing, Payment, and Records

Most jurisdictions require monthly returns. In Philadelphia, returns and payment are due by the 20th of the month following the distribution activity. A registered distributor files every month, even in periods with zero taxable distributions. Electronic filing through the local revenue department’s portal is typically the only accepted method, with payment by electronic funds transfer.

The return will require total volume of taxable beverages distributed, broken out by category — bottled and canned drinks in fluid ounces, syrups in gallons along with the finished-drink yield. Some forms also require separate reporting of exempt sales.

Records need to hold up on their own. Invoices, bills of lading, and delivery records should reconcile with the volumes on the return, and internal warehouse-to-delivery tracking should match your filed numbers. The IRS recommends keeping business tax records for at least three years from the filing date, or four years for employment tax records.2Internal Revenue Service. How Long Should I Keep Records Local beverage tax authorities may set their own retention periods, so defaulting to four years of complete records is the safer approach.

Penalties for Non-Compliance

Late filing and late payment carry separate consequences, and they stack. The specifics vary, but the general pattern is:

  • A percentage-based late-filing penalty on the unpaid tax for each month or partial month the return is overdue, often capped at 25 percent.
  • A smaller monthly late-payment penalty on the unpaid balance, also typically capped at 25 percent.
  • Daily interest on unpaid tax and penalties, usually pegged to the IRS underpayment rate.
  • Flat fines for registration or reporting failures. Philadelphia can assess a $1,000 penalty for non-compliance and revoke a business’s commercial activity license.

The larger cost of non-compliance is often operational rather than financial. Losing a business license or ending up on an audit watchlist causes problems that outlast any single fine. If you receive an assessment you believe is incorrect, most jurisdictions provide an administrative review or appeal process before litigation, and the filing window is generally short.

Preemption States

If you distribute in a state that has preempted local beverage taxes, no new city or county tax can be imposed on your distribution activity unless the legislature lifts the ban:

  • Arizona (2018)
  • California (2018, expires 2031; Berkeley, Oakland, San Francisco, and Albany are grandfathered)
  • Michigan (2017)
  • Washington (2018; Seattle is grandfathered)

Oregon’s general prohibition on local sales taxes also blocks local beverage taxes. Other states may have broader preemption frameworks that affect whether a city could adopt a soda tax. When evaluating a distribution location, check both the city’s ordinances and the state’s preemption rules before concluding you owe nothing — or everything.
