Welcome to the Property Tax Online Payment Website
Property tax statements for 2014 will be mailed on or around February 14 and amounts due will be posted online on February 13, 2014. Second half 2013 property taxes were due or must have been postmarked by October 31, 2013. Payments made after this date will be charged late fees. To make online payment(s), go to the King County E-commerce Property Tax Web page. It may take up to a week for your property tax payment to be reflected in our records after receiving your payment. If you pay online by electronic check (debit to your checking account), you should see this reduction in your bank account within three business days even though our system may not yet reflect the payment.
