Pierce County tax records are public and can be looked up three ways: online through the Assessor-Treasurer Information Portal (ATIP) at atip.piercecountywa.gov, by mail, or in person at the Assessor-Treasurer’s office in Tacoma. Washington law requires property listings and their supporting records to stay open for public inspection during regular office hours.1Washington State Legislature. Revised Code of Washington 84.40.020 The county’s Assessor-Treasurer handles both the valuation side and tax collection, so a single lookup pulls assessed value, current tax, payment history, and parcel details together in one place.2Washington Department of Revenue.

How to Search Pierce County Tax Records Online
The fastest route is ATIP, the Assessor-Treasurer Information Portal at atip.piercecountywa.gov. The portal returns property values, tax balances, and comparable sales data for any parcel in the county.3Pierce County, WA – Official Website. Assessor – Treasurer
The parcel number is the most reliable search key. You’ll find it on a property deed, a prior tax statement, a mortgage statement, or a title report. If you don’t have one, ATIP also accepts a street address, though not every search feature supports address lookups.4Pierce County, WA – Official Website.

Requesting Records by Mail or in Person
The Assessor-Treasurer’s office is at 2401 S. 35th St., Room 142, Tacoma, WA 98409, open 8:30 a.m. to 4:30 p.m. on business days.5Pierce County, WA – Official Website. Tax Bills and Payments Staff can pull specific documents or issue certified copies for banking or legal use.
To request records by mail, write to the same address. Include the parcel number or street address, note which documents you need, and enclose a self-addressed stamped envelope for the response. Copy fees for tax records aren’t fixed by the same statute that governs court records, so call the office first to confirm what your request will cost before you send payment.
What a Pierce County Tax Record Shows
A record pulls together the financial and physical facts about a parcel. On the financial side, you’ll see the assessed value split between land and improvements, the taxable value after any exemptions, the current year’s total tax, and the history of payments and any outstanding delinquencies. Washington requires property to be valued at 100 percent of true and fair market value.6Washington State Legislature. Revised Code of Washington Chapter 84.40 – Listing of Property
The physical side includes square footage, year built, number of rooms, and a legal description of the lot boundaries as the county recognizes them. For a buyer or someone refinancing, the payment history is where you confirm that prior taxes are actually paid and that nothing unexpected is sitting on the account.
Checking for Delinquencies and Foreclosure Status
If a tax record shows years of unpaid balances, that matters. When property taxes stay unpaid for three or more years and the total owed is more than $100, Pierce County is required by law to begin foreclosure. The Assessor-Treasurer files a Certificate of Delinquency with the Superior Court, which starts the legal process that can end with the property being sold at auction.7Pierce County, WA. Foreclosure
Properties in that pipeline appear on a Foreclosure Parcel List maintained by the Assessor-Treasurer’s office.3Pierce County, WA – Official Website.

Foreclosure If you’re researching a property to buy and the record shows a long delinquency, the foreclosure list is the next place to look.
Payment Deadlines If the Record Shows a Balance Due
For 2026, property taxes can be paid in two installments: the first half by April 30 and the second half by November 2. You can also pay the full year by April 30.8Pierce County. 2026 Property Taxes Arriving in Your Mailbox Soon One detail trips people up: Washington treats the entire year’s tax as delinquent if the first half isn’t paid on time, and interest accrues on the full amount. For residential properties with four or fewer units, the interest rate is 9 percent per year. Other property types face 12 percent annual interest plus penalties of 3 percent on June 1 and another 8 percent on December 1. Catching a problem on a record early is far cheaper than finding it years later.
Appealing the Assessed Value on Your Record
If the record shows a value you believe is too high, you can petition the Pierce County Board of Equalization. The board only considers whether the assessment exceeds 100 percent of fair market value, based on evidence you and the Assessor’s office submit.9Pierce County, WA – Official Website. Board of Equalization
File a petition within 60 days of the mailing date on your value change notice, or by July 1 of the assessment year, whichever is later.10Pierce County, WA. Appeals Mail the petition to the Pierce County Board of Equalization at 2401 South 35th Street, Room 176, Tacoma, WA 98409.9Pierce County, WA – Official Website. Board of Equalization The evidence that moves the needle is market-based: comparable sales of similar properties, contractor estimates for repair of real defects, documentation of easements or development costs that cut market value, and independent appraisals. Arguments about tax amount, affordability, or percentage increases won’t be considered, so build the file around market value and nothing else.
