How Washington Tax Sales Work

Washington sells tax deeds, not liens. Counties foreclose in superior court after three years, and redemption ends the day before the sale.

By Evan Reid, Founder of Tax Sale Atlas · Updated Aug 9, 2026 · 7 min read

Washington issues something called a certificate of delinquency, and the name has cost lien investors money. It goes to the county, never to a buyer. Washington sells the property itself, once, at a treasurer's auction held only after a superior court enters judgment against the parcel.

Treasurers, sale formats and county detail sit on the Washington tax sales hub. The governing chapter is RCW Chapter 84.64, Lien Foreclosure. If the structures still blur together, read tax liens compared to tax deeds first.

Step 1: Three years of delinquency, and interest that never reaches you

Taxes fall due April 30. Pay half by then and the balance is due October 31. Delinquent amounts carry interest computed monthly from the date of delinquency: 9 percent a year on residential real property with four or fewer units per taxable parcel, and 12 percent a year on everything else, plus penalties of 3 percent on June 1 and 8 percent on December 1 outside that residential class.

All of it belongs to the county. Washington has no instrument that pays any of it out, so the yield figures quoted for this state are borrowed from somewhere else.

Step 2: The certificate of delinquency is a county document

Three years after the date of delinquency, RCW 84.64.050 requires the treasurer to issue a certificate of delinquency to the county on every delinquent parcel, file it with the clerk of the superior court, and foreclose the lien in the county's name with the prosecuting attorney. Nobody bids on that paper and no rate attaches to it.

Two filters thin the list first. The treasurer cannot file where the delinquency is one hundred dollars or less excluding interest and penalties, unless the parcel is a declared nuisance, and cannot sell property eligible for deferral under chapter 84.38 RCW without a deferral declaration.

Service then gives the owner thirty days to defend or pay, and RCW 84.64.060 lets any holder of a recorded interest pay the taxes, interest and costs before the sale and take a lien for what they paid. A servicer protecting its position is the most common reason a promising parcel vanishes between the published list and the auction, so re-check the week of the sale.

Step 3: Redemption ends the day before the sale

The rule in one line: Until the close of business the day before the sale; no redemption after the sale except for minors and legally incompetent persons. The auction closes the door on a competent adult owner. No waiting period follows the sale, no redemption interest accrues, and nothing hands your money back on a parcel you regret.

One exception survives. Property of a minor or a person adjudicated legally incompetent may be redeemed within three years of the sale, for the sale amount plus interest from the sale date and the value of good-faith improvements, less the value of your use. That is the reason to check who owns a parcel rather than only what it is. See redemption periods explained for how short this sits beside a lien state.

Step 4: No statute fixes the sale month

The court's order of sale lets the treasurer set the date and time, excluding Saturdays, Sundays and legal holidays, with notice posted for ten days in three public places, and the sale continues day to day until every parcel sells. Most counties hold one auction a year and the month moves county to county, with nothing in the code to anchor it. Confirm it on each treasurer's own page, starting from the Washington county directory.

Step 5: The judgment is the floor, not the whole bill

The court enters judgment for the taxes, interest and costs due, and that total is the smallest bid the treasurer can accept. Here is the trap. RCW 84.64.200 requires every bidder except the county to pay all taxes, interest and costs delinquent at the time of sale, even where the judgment left them out. A parcel judged on older years can pick up another year of taxes before auction day, and that lands on the winner.

Model the gap first. The tax deed max bid calculator carries Washington's cost rules, and due diligence before a tax sale covers the searches worth running while the parcel is still listed.

Step 6: Deposits and payment depend on the format

RCW 84.64.225 lets the treasurer conduct the auction by electronic media, and the larger counties commonly do. For an auction conducted by electronic media, prospective bidders must deposit funds with the treasurer to participate, deposits of non-winning bidders are refunded within ten business days, and payment is by electronic funds transfer. Deposit amounts for in-person sales are set county by county, so confirm the figure on the county treasurer page or the auction platform terms.

Read the second half of that twice. Those deposit, refund and payment terms govern electronic sales. An in-person courthouse sale runs on county practice inside the same legal frame, cash on the day in most counties, on terms the treasurer announces rather than publishes. Settle the format and the money deadline before you register.

Step 7: What the tax deed actually gives you

The treasurer executes a tax deed, recorded like any other conveyance, vesting title in the grantee. RCW 84.64.180 makes it prima facie evidence that the property was taxable, that the taxes went unpaid, that nobody redeemed and that the sale followed the law, and the judgment estops prior parties from objections that existed at or before it. Two attacks survive: taxes actually paid, and property that was never taxable.

Prima facie evidence sits a long way from insurable title, and the property sells as is with no warranty as to title, zoning or use. Read what survives a tax deed for what a tax foreclosure leaves alone, and budget for quiet title after a tax deed before counting on a resale.

The surplus belongs to the former owner

Bid above the minimum and the excess goes to the record owner, whoever held title when the certificate of delinquency was issued. That party has three years from the sale to claim it, after which the money moves to the county current expense fund and the claim dies. None of an overbid comes back to the buyer.

Buying what nobody bid on

When no bid covers the minimum, the county is deemed the bidder and takes title in trust for the taxing districts. That inventory becomes tax-title property, resold under chapter 36.35 RCW: the county legislative authority orders the sale and fixes a minimum price, the treasurer publishes notice once a week for three consecutive weeks, and nothing sells below that price. Counties may take installment contracts of thirty percent down and ten equal annual payments at twelve percent interest.

Some dispositions skip bidding, including a sale within twelve months after an auction that drew no acceptable bid, a sale to a government agency, and a parcel assessed under five hundred dollars sold to an adjoining owner. Washington keeps no statewide lands-available list and some counties go years between tax-title sales. See the Washington over-the-counter page and over-the-counter tax liens for how leftover inventory differs by state.

Putting it together

Washington rewards buyers who finish the work before the auction and want a property rather than a yield. Three things decide a deal here: the sale month, which you have to go and find county by county; the delinquency owed at the time of sale on top of the judgment; and the title work waiting past the deed. When a parcel clears all three, follow how to buy tax deeds in Washington for the registration and bidding sequence.

Frequently asked questions

Does Washington sell tax liens or tax deeds?
Tax deeds only. The certificate of delinquency goes to the county itself and is never sold to investors. The county forecloses in superior court and the treasurer auctions the property.
How long must a Washington property be delinquent before foreclosure?
Three years from the date of delinquency. The treasurer issues the certificate of delinquency and files the superior court action, and the owner has thirty days to defend or pay, so parcels usually reach auction in the fourth year.
Can a Washington owner redeem after the tax foreclosure sale?
Generally no. Redemption runs until the close of business the day before the sale. Property of a minor or a person adjudicated legally incompetent may be redeemed within three years of the sale, for the sale amount plus interest and the value of good-faith improvements.
What is the minimum bid at a Washington tax foreclosure auction?
The judgment amount: all taxes, interest and costs the court found due. Every bidder except the county also pays any taxes, interest and costs delinquent at the time of sale, even where the judgment left them out.
Are Washington tax foreclosure auctions held online?
Many are. RCW 84.64.225 lets the treasurer sell by electronic media. Bidders post a deposit, losing deposits return within ten business days, and the winner gets no less than forty-eight hours to pay by electronic funds transfer. Smaller counties may still sell in person.
Can you buy Washington tax property over the counter?
Not from a standing list. Parcels drawing no sufficient bid go to the county as tax-title property, resold under chapter 36.35 RCW at a price the county legislative authority fixes. Availability varies widely, so check the county tax-title page.
