Understanding Island County Tax Rates

Island County, Washington, follows the state's combined sales tax structure, which includes a base rate set by the Washington State Department of Revenue plus additional local rates imposed by the county and cities. As of the latest data, Washington does not levy a personal or corporate income tax, making sales tax a primary revenue source.

• State Base Rate: Washington's statewide sales tax rate is currently 6.5%.
• Local Additions: Island County and its cities (such as Oak Harbor, Coupeville, and Langley) may add incremental taxes, resulting in a total combined rate between 8.0% and 8.6%, depending on location.

Special taxing districts, such as public transportation or public safety, may also apply additional small percentages.

What's Taxable in Island County?

Washington State imposes sales tax on most retail goods and services, with some key exemptions:

• Taxable Items: General merchandise, prepared food, utilities, digital products, and services like construction or cleaning.
• Common Exemptions: Groceries (unprepared food), prescription drugs, and medical equipment are exempt. Clothing is taxable unless specifically exempted by local ordinances.

Businesses must also pay Business & Occupation (B&O) tax on gross receipts, though this is separate from sales tax.
