Washington's Tax Deed Surplus: Three Years to Claim, Then It's Gone for Good
Washington doesn't sell tax lien certificates. The county treasurer sells the property itself at a public tax deed auction once taxes have gone unpaid long enough, and the owner can redeem only until the close of business on the day before the sale (RCW 84.64.070). The one exception is a minor or a person adjudicated legally incompetent, who can redeem within three years after the sale. That makes the surplus question sharper here than in a lien state: if the winning bid exceeds the delinquent taxes, interest, and costs, the difference (excess funds) belongs to whoever held title on the day the treasurer issued the certificate of delinquency.
The statute and who gets notified
Under RCW 84.64.080, the excess amount is held for the party who held title on the filing date of the Certificate of Delinquency — that's the reference date, not the auction date. In practice, most county treasurer's offices (King, Spokane, Island, and others publish their own pages on this) send the former owner a letter and a claim application once the sale closes and the excess is confirmed, rather than requiring the owner to go looking for it unprompted.
The clock: three years, then the county keeps it
The owner has three years from the sale to submit the claim. After three years with no request, the treasurer moves the money into the county's current expense fund, which ends every claim to it (RCW 84.64.080(10)). Unlike some states where unclaimed surplus eventually lands in a state unclaimed-property registry you can still search years later, Washington's excess funds simply become county revenue once the window closes.
Be careful with finders
People who offer to "find" and recover these funds for a cut often cite an old 5% cap on finder's fees in RCW 63.29.350. That section was repealed effective January 1, 2023, when Washington replaced its unclaimed property law (Laws of 2022, ch. 225). Don't rely on that cap. The treasurer that held the sale will tell you how to claim directly, and the claim itself doesn't need a middleman.
Why the short redemption matters for investors
Because there's no post-sale redemption window, a Washington tax deed auction is closer to a clean transfer than states where the certificate holder waits out a multi-year redemption before getting anything resembling ownership. That also means any equity above the tax debt gets resolved quickly, at the auction itself, rather than being locked up for years the way it can be in a lien state — worth factoring in if you're comparing Washington against slower-moving states for the same reason.
