Seattle restaurant taxes stack in layers: a 10.25% retail sales tax on every prepared meal, a per-ounce sweetened beverage tax on qualifying drinks, spirits taxes baked into cocktail prices at the wholesale level, two separate business and occupation taxes on gross revenue, tightly regulated service charge disclosures, and filing penalties that climb month by month. Each piece has its own rules, and missing any one of them is expensive.
Sales Tax on Prepared Food and Drinks
The combined retail sales tax rate on prepared food in Seattle is 10.25%. Of that, 6.5% is Washington’s statewide base rate, and the remaining 3.75% comes from overlapping city, King County, and regional transit levies.1Washington State Legislature. Washington State Code 82.08.020 – Tax Imposed, Retail Sales, Retail Car Rental The rate is the same whether the customer eats in, takes the food to go, or has it delivered.
Restaurants collect the tax at the point of sale and hold those dollars in trust until they reach the Department of Revenue. Using that money for anything else is a gross misdemeanor under state law.2Washington State Legislature. Washington State Code 82.08 – Retail Sales Tax
One useful carveout: meals given to employees at no separate charge are exempt from retail sales tax. Shift meals don’t need to be rung up and taxed.3Washington State Legislature. Washington State Code 82.08.9995 – Exemptions, Restaurant Employee Meals
Sweetened Beverage Tax
Seattle adds an excise tax of 1.75 cents per fluid ounce on sweetened beverages distributed inside city limits. That’s 21 cents on a 12-ounce can of soda. The tax covers sodas, energy drinks, sweetened teas and coffees, flavored waters with added sugar, and juice drinks with caloric sweeteners.4Seattle.gov. Ordinance 125324 – Sweetened Beverage Tax
Several categories fall outside the definition entirely:
- Beverages where natural milk is the first listed ingredient, and drinks whose first two ingredients are water and grains, nuts, legumes, or seeds.
- 100% fruit or vegetable juice with no added sweetener.
- Anything under 40 calories per 12-ounce serving.
- Baby formula, meal replacement liquids, medical electrolyte drinks, and sweetened medications.
- Alcoholic beverages and concentrates the consumer mixes at home.
The tax legally lands on distributors, but the cost typically flows into menu prices or appears as a separate line on the check. Restaurants sourcing from a certified small manufacturer with $2 million or less in worldwide gross revenue owe no sweetened beverage tax on those products, and manufacturers between $2 million and $5 million qualify for a reduced rate of one cent per ounce.5City of Seattle.

Alcohol: Spirits, Beer, and Wine
Spirits taxes are widely misread. The spirits-specific taxes apply only to sales in the original sealed container. A cocktail or a whiskey pour served by the glass is subject to the regular 10.25% retail sales tax, not the spirits sales tax.6Washington Department of Revenue. Spirits (Hard Liquor) Sales Tax
The spirits taxes hit the restaurant at the wholesale level. When a restaurant buys bottles from a distributor, it pays a 13.7% spirits sales tax on the purchase price plus a spirits liter tax of $2.4408 per liter.7Washington Department of Revenue. Spirits Sales – Sales Involving Tribes Those costs get built into every cocktail on the menu, which explains why a mixed drink runs noticeably higher than a beer or a glass of wine.
Beer and wine sold by the glass carry only the standard 10.25% retail sales tax. Separate producer- and distributor-level excise taxes exist on beer and wine but do not appear on a restaurant bill as distinct charges.
Business and Occupation Taxes on Gross Revenue
Two B&O taxes come straight off a restaurant’s top line. Customers never see them, and there is no deduction for cost of goods sold or labor.
State B&O
Washington taxes restaurant revenue under the retailing classification at 0.471% of gross receipts. A restaurant grossing $1 million owes roughly $4,710 whether or not it turns a profit.8Washington Department of Revenue. Business and Occupation (B&O) Tax
Seattle City B&O
Effective January 1, 2026, Seattle raised its retail B&O rate to 0.342% and lifted the threshold below which no tax is owed from $100,000 to $2 million in annual taxable revenue. A separate $2 million standard deduction is available to businesses above the threshold, so a restaurant with $3 million in taxable revenue pays 0.342% only on the $1 million above the deduction.9Seattle.gov. City Finance – Business Taxes
Restaurants under the $2 million threshold still have to file the annual Seattle B&O return and report gross revenue, even when nothing is owed.10Seattle.gov. Seattle Shield Business and Occupation (B&O) Tax Changes
Service Charges and Automatic Surcharges
Lines labeled “service charge,” “house charge,” or “economic surcharge” often help cover Seattle’s $21.30 minimum wage and paid sick leave costs.11Seattle.gov. Minimum Wage They are not taxes, but Washington regulates how they must be disclosed.
Any restaurant adding an automatic service charge has to state on both the menu and the receipt what percentage goes to the employee serving the customer. If the restaurant keeps part of the charge for overhead, the split has to be spelled out. When the disclosure is missing or unclear, the entire charge is owed to the employee.12Washington State Legislature. Washington State Code 49.46.160 – Service Charges, Required Disclosure13Washington State Department of Labor & Industries. Tips and Service Charges
The IRS draws a firm line between voluntary tips and mandatory service charges. A payment counts as a tip only when the customer freely chooses the amount. Automatic charges added to a bill are service charges regardless of what the receipt calls them, and employers must run any service charge distributed to staff through regular payroll withholding as wages.14Internal Revenue Service. Tips Versus Service Charges – How to Report A “mandatory gratuity” on a large party is not a tip for tax purposes, even though it feels like one to the server and the customer.
Filing Schedule and Late Penalties
The Department of Revenue assigns each restaurant a filing frequency based on estimated gross annual income. Restaurants earning up to $60,000 a year file quarterly; anything above $60,000 files monthly. Annual filing is not available to food service businesses.15Washington Department of Revenue. Filing Frequencies and Due Dates
Monthly returns are due by the 25th of the following month. Quarterly returns are due by the end of the month after the quarter closes, so first-quarter returns are due April 30. Deadlines falling on a weekend or holiday roll to the next business day.
Penalties climb fast:
- Immediately past due: 9% of the unpaid tax, minimum $5.
- One month late: 19%.
- Two months late: 29%.
The Department can waive penalties in limited situations, generally when the failure was caused by circumstances beyond the taxpayer’s control. Not knowing taxes were due, or not having the cash on hand, does not qualify. A clean 24-month compliance history may earn a one-time waiver, and that opportunity resets only after another 24 months of on-time filings.16Washington Department of Revenue. Penalty Waivers
Seattle Business License Tax Certificate
Every Seattle restaurant needs a city business license tax certificate, separate from state registration and health permits. Annual fees are tiered by the prior year’s gross revenue:
- Under $20,000: $73
- $20,000 to $499,999: $147
- $500,000 to $1,999,999: $667
- $2 million to $5 million: $1,604
- Over $5 million: $3,210
New businesses default to the Tier 1 fee in their first year. Anyone starting on or after July 1 pays half. Each additional branch location costs $10. Applications go through Seattle’s FileLocal portal, and the business needs a state UBI number first.17Seattle.gov. Business Licenses
