Washington tax sales by county

Verified

Washington is a treasurer sale state with a court case inside it. The county treasurer waits three years from delinquency, issues a certificate of delinquency to the county, and forecloses in superior court, where a judge signs the judgment and the order of sale (RCW 84.64.050, 84.64.080). The treasurer then sells the property itself at public auction, to the highest and best bidder, as is, in a room or, in every large county in this set, online. Three corrections run through this whole page set. The minimum bid, the total of taxes, interest and costs, is not the price of the deed: the winner also pays every tax, interest charge and cost delinquent on sale day, in or out of the judgment (RCW 84.64.200). Redemption ends at the close of business the day before the sale, not when the auction opens (RCW 84.64.070). And the interest story is split: 9 percent on homes of four or fewer units, 12 percent on everything else, with the 3 and 8 percent penalties falling only on nonresidential, larger residential, and personal property (RCW 84.56.020).

This page set covers the top 10 Washington counties by population, each verified against its treasurer's own publications, and the winter season is live: Pierce County's annual foreclosure auction runs online on Monday, November 9, 2026. Whatcom County sells Tuesday, December 1 to Wednesday, December 2, 2026, Yakima County Wednesday, December 2 to Thursday, December 3, 2026, and Snohomish County publishes Thursday, December 3, 2026 as a tentative date to be fixed by its Final Order of Sale. King County last sold on Wednesday, September 9, 2026 online, with later offers the same month, and publishes a December tax title auction, the chapter 36.35 resale of parcels the county already holds, with no exact date. Clark County runs a February cycle, last held Tuesday, February 10 to Wednesday, February 11, 2026; Thurston County's last published sale began Monday, January 12, 2026. Kitsap, Spokane and Benton Counties publish no dated next sale in the official sources read; Spokane's current cycle terms are not published at all, and Benton publishes the pattern, a June process start and a November sale, without a date.

Verify before you go: counties can move a date, change terms, cancel a sale, or pull parcels at any time. The official sale list is the final word.

Each row links to that county's own page: selling office, venue or platform, deposit, payment terms, leftover channel, and sources. Where a county has not posted a dated sale, the row says so instead of projecting a pattern onto it.

How Washington tax foreclosure sales work

• Washington foreclosure starts three years out, and the small print removes parcels before any sale exists. Property taxes are due April 30 with the second half due October 31, and delinquent taxes bear interest computed monthly at 9 percent per annum for residential property with four or fewer units (taxes levied in 2023 or after) and 12 percent for everything else (RCW 84.56.020). Penalties of 3 percent on June 1 and a further 8 percent on December 1 fall only on nonresidential property, residential property over four units, and personal property; small residential parcels pay no penalties at all, which is why the flat 12 percent interest and 11 percent penalty figures in national summaries are wrong for the common Washington house. After three years from the date of delinquency the county treasurer must issue a certificate of delinquency to the county (RCW 84.64.050), but no certificate issues where the delinquency excluding interest and penalties is 100 dollars or less unless the parcel is a declared nuisance, and property eligible for the senior and disability deferral under chapter 84.38 RCW may not be sold at all.
• The foreclosure is a court case, and the judge signs the sale order. The treasurer files the certificate with the clerk of the court and forecloses in the name of the county in superior court, with the county prosecuting attorney assisting (RCW 84.64.050). Notice goes by personal service or by one publication plus certified mail to the owner and every recorded interest holder, with 30 days to appear and defend or pay, and the treasurer must complete a title search before the sale so a record titleholder who differs from the name on the treasurer rolls gets the same notice. The court enters judgment for the taxes, interest and costs on each tract and an order of sale signed by the judge (RCW 84.64.080). There is no administrative shortcut around that judgment, and the judgment estops later objections except that the tax was paid or the property was not liable to taxation (RCW 84.64.180).
• The minimum bid is real, and it is not the cash the deed costs. The acceptable minimum bid at the sale is the total amount of taxes, interest and costs (RCW 84.64.080), and in chapter 84.64 the word interest itself includes the penalties (RCW 84.64.005). But a winning bidder other than the county must pay the full amount of the judgment together with all taxes, interest and costs delinquent at the time of the sale, whether or not they were included in the judgment (RCW 84.64.200). The gap between the printed minimum and the payoff on sale day is where unprepared Washington buyers get surprised; the treasurer's payoff figure in the sale week is the funding number, not the number printed beside the parcel.
• Redemption ends the day before the sale, with one exception that outlives it. Any person owning a recorded interest may pay the taxes, interest and costs at any time before the day of the sale (RCW 84.64.060), and the property may be redeemed at any time before the close of business on the day before sale day, for the certificate amount with interest plus all later taxes, interest and costs, with no redemption fee (RCW 84.64.070). After the sale there is no general redemption. The exception: property of a minor or of a person adjudicated legally incompetent may be redeemed within three years after the sale, on payment of the sale amount with interest plus the reasonable value of good faith improvements less the value of use (RCW 84.64.070). A buyer of a parcel whose owner fits that exception holds a defeasible deed for three years, and the exception is invisible on most sale lists.
• The sale is an as-is auction, in a room or online, and the room rules are the treasurer's. The treasurer sells to the highest and best bidder, the property sold as is without any warranty of title, buildability, zoning, size, location or fitness. An in person sale runs on a weekday at a location in the county after notice is posted for ten successive days in three public places including the treasurer office (RCW 84.64.080). An electronic media sale runs under RCW 84.64.225 and RCW 36.16.145 after newspaper publication once a week for two successive weeks and posting at the courthouse and on the county website at least 14 days ahead; the flagship counties in this set sell this way, on the platforms their own pages name. Bidder deposits are a treasurer term, not a statute term, and in an electronic sale the winning bidder gets no less than 48 hours to pay by electronic funds transfer. Deposits in this set run from 1,000 dollars to 2,500 dollars plus a platform fee, which is why the platform terms for the sale in front of you are a required read.
• Only one class of bidder is barred by statute. No county officer or employee may directly or indirectly purchase at the sale (RCW 84.64.080). Nothing in the chapters read bars the delinquent former owner from bidding, and nothing bars a bidder who owes delinquent taxes somewhere else; summaries that add those bars are importing other states' rules. Counties and platforms add their own conduct terms on top, and those terms, not a phantom statute, are what can disqualify a bid.
• The deed is quick, and the challenge clocks are short and specific. The treasurer executes and records a tax deed that vests title in the purchaser without further acknowledgment, collecting a five dollar preparation fee plus the recording fee through the county auditor (RCW 84.64.080 and 84.64.215). An appeal from the foreclosure judgment must be sought within 30 days and requires a deposit of the full taxes, interest and costs (RCW 84.64.120). An action to set aside or cancel the deed or to recover the land must be brought within three years after the deed issues (RCW 4.16.090). Buyers who need insurable title sooner than that horizon price a quiet title action into the purchase, the same as in Utah.
• Surplus goes back to the record owner on application, under a rule older than Tyler. If the highest bid exceeds the minimum bid, the excess, after payment of recorded water and sewer district liens, must be refunded on application to the record owner, meaning the person who held title on the date the certificate of delinquency was issued, with later assignments and deeds disregarded (RCW 84.64.080). The application must reach the treasurer within three years after the sale; after that the excess goes into the county current expense fund and all claims are extinguished. The rule was last amended in 2019, so it predates Tyler v. Hennepin County rather than answering it, and it stands in contrast to the county resale channel below, whose proceeds carry no former owner claim at all.
• Parcels nobody bids on become county tax title land, and the county resale is a different sale. If no other bid is received, the county is considered the bidder for the full amount due and takes title in trust for the taxing districts; the parcel is stricken from the tax rolls as tax title land under chapter 36.35 RCW (RCW 84.64.200 and 36.35.100). The county legislative authority may later order it sold at a minimum price the authority itself fixes, after three weeks of published notice, to the highest bidder for cash or on a contract with 30 percent down and the balance in ten equal annual installments at 12 percent interest, or dispose of it by private negotiation without bids in the cases stated in RCW 36.35.150, including a sale within 12 months after a public auction drew no acceptable bids. Resale proceeds pay foreclosure and sale costs first, then deferred tax amounts, then the taxing funds, and RCW 36.35.110 states no claim for the former owner. King County's December tax title auctions run on this channel, not on the foreclosure calendar.

One Washington fact decides most purchases: the minimum bid is not the price of the deed. The winner pays the judgment plus every tax, interest charge and cost delinquent on sale day whether or not it was in the judgment, so the funding number is a payoff quote from the treasurer in the sale week, not the number printed next to the parcel.

Research the parcels before you bid

A sale list gives you the parcel, the date, and the opening terms. It does not give you the owner, the value, or the rest of the picture: liens, foreclosure status, and parcel history. PropertyRadar is the data platform for that layer. It carries owner records, assessed and market values, foreclosure and tax data, and property history for parcels across the country, searchable by address, owner, or county, including parcels that never reach a sale list.
