A Complete Small Business Tax Guide: Washington State (2024)

Washington, the Evergreen State, with its world-class cities of Seattle, Vancouver, and Spokane, is a popular place to establish a business. While there is no personal or corporate income tax, you would be responsible for paying other taxes, contributing to Washington's high overall tax burden.  

Thriving in such a unique environment takes effort and planning, including a strategic approach to business tax liability. Use this blog as your complete guide to small business taxes in Washington state in 2024. 

Washington State Small Business Taxes

Washington is not considered a tax-friendly state, which may be surprising considering there's no corporate or income tax. Instead, Washington collects other taxes, including property and sales tax.

What you'll pay in property taxes will vary by region, but the average across the state is usually 1% of the real estate's market value. State sales tax is 6.5%, which can inflate to nearly 10% when local sales tax is factored in. 

Small Business License in Washington State

You should register your business with Washington's Department of Revenue (DOR) if it meets any of the following requirements: 

Your business will require endorsements from the city, county, or state.

Your business must pay taxes or fees to the DOR.

Your business meets the threshold for Nexus reporting requirements.

Your business is a buyer or processor of specialty wood products.

You are doing business using a name other than your full legal business name.

You're planning to hire employees within 90 days.

You sell products or services that require the collection of sales tax.

Business and Occupation Tax in Washington State

Washington's Business and Occupation (B&O) tax is a gross receipts tax that measures the value of products, gross proceeds of sale, or gross income of your business.

This tax does not allow deductions for labor, materials, and other operating costs because it is calculated based on gross income. However, there are credits and exemptions available for the B&O tax. 

Small Business Tax Credits

You are entitled to a credit if your business is under a B&O tax liability threshold. The credit your business receives will depend on the total amount of B&O tax due for all classifications after you've taken any other B&O tax credits.

Activities that can help your business qualify for B&O tax exemptions and deductions include:

Caring for children under eight years old and below the first grade.

Care by a church exempt from property taxes for periods of less than 24 hours.

Health or social welfare services funds received.

Like the Washington state sales tax, many localities charge a B&O tax specific to their region. This local B&O tax is in addition to the tax charged by the state of Washington.
