How gasoline excise tax applies in Seattle

There is no separate, city-level gasoline excise tax published on the City of Seattle taxes pages; fuel excise duties that appear on receipts come from Washington State statutory and administrative tax authorities. Official statewide fuel tax rates, exemptions, and distributor registration requirements are published by the Washington State Department of Revenue and related state agencies.[1] For local business licensing and tax registration requirements that may affect fuel retailers in Seattle, consult the City of Seattle taxes and licensing pages.[2]

Rate components and who sets them

  • State excise tax per gallon - set by Washington statutes and adjusted administratively.
  • Federal fuel-related fees where applicable - set by federal law (applies to some fuels and uses).
  • Local sales or business taxes applied by Seattle on fuel sales receipts - administered by the city and listed on local tax pages.

Penalties & Enforcement

Enforcement of motor fuel excise tax compliance for activities that affect Seattle is primarily handled by Washington State tax authorities, with city agencies overseeing licensing, sales tax collection, and local compliance where applicable. Specific monetary fines and penalty schedules are set in state law and administrative rules; exact dollar amounts and per-day penalties for particular violations are not specified on the cited city page and should be confirmed on the Washington State Department of Revenue pages referenced below.[1]

  • Fine amounts: not specified on the cited page; see state enforcement pages for statutory penalty rates and interest schedules.[1]
  • Escalation: first, repeat, and continuing offences are handled per administrative rules; ranges or automatic escalations are not specified on the city page.[1]
  • Non-monetary sanctions: assessments, collection actions, license suspension or revocation, and referral to courts may apply as provided under state law and administrative procedures.
  • Enforcer and complaint pathway: primary enforcement is the Washington State Department of Revenue; for Seattle-specific licensing or business tax complaints, contact City of Seattle Finance and Administrative Services or the Business Licensing unit.[2]
  • Appeals and review: administrative protest and appeal routes exist through the state tax appeals process; specific time limits and filing deadlines are set in state rules and should be confirmed with the Department of Revenue (time limits not specified on the cited city page).[1]
If you are a fuel distributor or retailer, register with state agencies before selling taxed fuel.
