Washington has no personal income tax on wages, so most owners file only a federal income tax return. Business-level taxes can still apply, so your books still need to be accurate.
Washington’s statewide base sales tax rate is 6.5%. Local taxes are often added on top, so the rate you charge depends on where your sales happen. We track sales tax collected separately from revenue so filing is simple.
Washington has no personal income tax, but businesses pay the Business and Occupation (B&O) tax on gross receipts.
Seattle levies its own business license tax on gross receipts in addition to the state B&O tax.
Most Washington business filings go to the Washington Department of Revenue. We keep your books organized so these returns are a simple handoff to you or your CPA.
