About Property Taxes in Washington
Washington State property taxes are administered at the county level. Property is assessed at 100% of its true and fair market value as of January 1. Washington levies both a state property tax (used for schools) and local taxes (county, city, school district, fire district, and others). The combined rates vary significantly by county. Washington's property tax system has strong protections for seniors and low-income homeowners, including an exemption that reduces or eliminates taxes for qualifying households regardless of property value.
Payment & Assessment
Washington property taxes are paid in two equal installments: First half: Due April 30 Second half: Due October 31 If the total tax is under $50, the full amount is due April 30. An interest charge of 12% per year applies to late payments, plus a 3% penalty on the first half and 8% on the second half if unpaid. Most counties offer online payment through the county treasurer's website. Contact your county for payment options.
