Washington REET Guide for Seattle Home Sellers (2026)
Washington State's Real Estate Excise Tax (REET) is one of the few US state-level transfer taxes with a progressive rate structure — sellers of higher-value properties pay a higher percentage. Understanding your REET obligation is essential for accurate net proceeds calculation.
Washington State REET Rate Structure (2026)
Washington's REET uses a graduated rate structure based on sale price:
The graduated rate applies to the portion of the price in each bracket, similar to marginal income tax brackets.

REET is typically a seller obligation in Washington.
Local REET Additions
In addition to the state REET, Washington's counties may impose an additional local Real Estate Excise Tax. King County (Seattle) does not impose a separate local REET on top of the state rate. However, some Washington counties have local additions. Confirm with your escrow officer.
Who Pays REET and When
REET is paid at closing through the escrow company. The escrow officer collects the tax and remits it to the Washington Department of Revenue. As a seller, you'll see the REET deducted from your proceeds on the closing statement.
REET Exemptions
Certain transfers are exempt from Washington REET:
Most standard sale-at-market-value transactions are subject to REET. Consult your closing attorney or escrow officer about specific exemptions.
REET vs. Other Washington Closing Costs
Washington has no other significant state-level seller costs beyond REET. Washington does not have a state income tax, and there are no separate documentary stamp taxes.
Your closing costs as a Washington FSBO seller:
Compare to a full-commission sale where you'd pay the above plus 3% listing commission — a $600,000 Seattle sale at 3% listing = $18,000 in commission vs. your flat fee of $199–$499.
King County vs. Snohomish and Pierce Counties
Real estate prices in King County (Seattle, Bellevue, Redmond, Kirkland) are significantly higher than Snohomish County (Everett, Lynnwood, Bothell) or Pierce County (Tacoma, Puyallup). The REET graduated rate means higher-priced King County transactions pay a higher effective REET rate. This is particularly relevant for Eastside (Bellevue, Redmond, Kirkland) sales where prices often exceed $1M.
