Washington is one of a handful of states with no personal income tax, but it is far from a no-tax state for businesses. Instead of a corporate income tax, it imposes a Business & Occupation (B&O) tax levied on gross receipts, and it has a robust statewide sales and use tax layered with local rates. Lodging and tourism taxes add another layer for hospitality, short-term-rental, and campground operators.

Washington Business Tax Guide
Washington is one of a handful of states with no personal income tax, but it is far from a no-tax state for businesses. Instead of a corporate income tax, it imposes a Business & Occupation (B&O) tax levied on gross receipts, and it has a robust statewide sales and use tax layered with local rates. Lodging and tourism taxes add another layer for hospitality, short-term-rental, and campground operators.
Washington has no state personal income tax, so owners of pass-through entities (S corporations, partnerships, LLCs) and sole proprietors do not file a Washington return on their share of business profits or on wages. This is a durable, defining feature of the state's tax structure. One caveat owners should know: Washington enacted a capital gains tax that applies to certain long-term gains on the sale of assets like stocks and bonds, which can reach business owners on the sale of investment assets, though it generally does not apply to most real estate or to ordinary operating income. Because there is no personal income tax, Washington also has no pass-through entity (PTE) tax workaround, since there is no state income tax for such an election to offset.
Washington does not levy a traditional corporate or net-income tax. In its place is the Business & Occupation (B&O) tax, which is assessed on gross receipts, meaning the tax applies to your gross income from business activity regardless of whether the business is profitable. The B&O rate depends on your classification (for example, retailing, wholesaling, service, or manufacturing), so businesses with multiple activity types may report under more than one classification. Because the B&O tax is gross-based with no deduction for most costs, thin-margin businesses can owe tax even in a loss year, which makes accurate classification and tracking of available credits important.
Washington has a statewide sales and use tax, and local jurisdictions (cities, counties, and transit districts) add their own rates on top, so the combined rate varies meaningfully by location and is determined by where the buyer takes delivery. Use tax applies to taxable goods used in Washington when sales tax was not collected at purchase, such as out-of-state or online purchases. Remote sellers and marketplace facilitators can establish economic nexus through their volume of Washington sales even without a physical presence, triggering an obligation to register, collect, and remit. Multi-state businesses should monitor where their sales create both sales-tax and B&O collection and reporting duties.
Short-term-rental, campground, RV-park, and hotel operators in Washington collect retail sales tax on lodging plus additional lodging-specific taxes that fund tourism and convention activities, which vary by city and county. Many local jurisdictions impose a special hotel/motel lodging tax, and some areas (such as certain King County and Seattle-area zones) layer on convention and tourism assessments, so the total tax a guest pays differs significantly by location. STR operators booking through platforms should confirm exactly which taxes the marketplace collects and remits on their behalf versus which remain the host's direct responsibility, since gaps here are a common source of liability. Operators generally must register with the Department of Revenue and report lodging activity even when a platform handles part of the collection.
Most businesses operating in Washington must obtain a state business license and register with the Department of Revenue, which assigns a reporting frequency (such as monthly, quarterly, or annual) based on the size of the business. B&O tax, sales tax, and lodging taxes are generally reported together on the same combined excise tax return, which consolidates several obligations into one filing. Because the B&O tax is gross-receipts based and rates differ by classification, careful records of gross income by activity, taxable versus exempt sales, and sales by delivery location are essential to file accurately. Confirm current rates, classifications, and due dates with the Washington Department of Revenue, as these are periodically updated.
Beyond the state B&O tax, many Washington cities (including Seattle, Tacoma, Bellevue, and others) impose their own separate municipal B&O tax with distinct rules, thresholds, and apportionment, so a business operating in multiple cities may face several local B&O filings in addition to the state return. Washington also uses destination-based sales tax sourcing, meaning the rate is based on where the customer receives the goods rather than where the seller is located, which complicates compliance for businesses delivering or providing services across jurisdictions. For real-estate investors and operators, the state's real estate excise tax (REET) applies to the sale of real property and is typically tiered based on the sale price.
Washington's gross-receipts B&O tax, layered state and local sales taxes, and city-level filings make it one of the more deceptively complex states to operate in despite having no income tax. Parikh Financial handles multi-state bookkeeping, B&O classification and city filings, economic-nexus tracking, and lodging-tax compliance so STR, campground, hospitality, and real-estate operators stay accurate and audit-ready.
