Washington REET Guide for Seattle Home Sellers (2026)
Washington state has no income tax — but it does have a Real Estate Excise Tax (REET) that sellers pay at closing. For Seattle homeowners selling at $800,000+, this is one of the largest closing cost line items and worth understanding clearly.
What Is REET?
The Real Estate Excise Tax is a Washington state tax on the transfer of real property. It is paid by the seller at closing. Your title/escrow company calculates and files the REET affidavit automatically — you don't do this yourself.

Washington uses a graduated (tiered) rate structure:
Note: Some cities and counties also levy a local REET on top of the state rate. Seattle (City of Seattle) charges an additional local REET that varies. Confirm with your title company for the total rate applicable to your specific address.
