Pierce County Property Tax: Rates, Exemptions & Appeals (2026)

Quick Answer

If you disagree with your 2026 assessed value, file a petition with the Pierce County Board of Equalization — not the Assessor-Treasurer — by July 1 of the assessment year, or within 60 days of the mailing date on your Notice of Value Change, whichever is later. Petitions go to the Board's office at 2401 South 35th Street, Room 176, Tacoma, WA 98409. This appeal deadline is completely separate from your property tax payment due dates, which fall in April and October — more on that below.

How Assessments Work in Pierce County

The Pierce County Assessor-Treasurer determines the assessed value of every parcel in the county. Washington law sets the valuation (lien) date as January 1 of the assessment year, and that value becomes the basis for taxes billed the following year — for example, your 2025 assessed value (as of January 1, 2025) determines your 2026 tax bill.

Pierce County revalues property on an annual basis using current market trends, but state law (RCW 84.41.030) also requires a physical, on-site inspection of every property at least once every six years. In practice, roughly one-sixth of the county is physically inspected each year, while the rest are adjusted statistically based on market data. If your area wasn't physically inspected this cycle, your new value was likely generated by a statistical model rather than an inspector walking your property — which is itself common grounds for review if the model got your home's characteristics wrong.

Should You Appeal — and What Actually Persuades the Board

Start with an informal check before filing anything. Look up your parcel on the Assessor-Treasurer's website and call (253) 798-6111 to confirm the county has your property's characteristics right — square footage, bedroom/bathroom count, condition, lot size. A large share of valuation problems are simple data errors the Assessor's office can correct without a formal hearing.

If the value still looks wrong after that, the Board of Equalization is a quasi-judicial body that is completely independent of the Assessor-Treasurer's office — its only job is to decide whether your assessed value exceeds 100% of your property's true market value as of the assessment date. The burden of proof is on you: the assessed value is presumed correct, and you need "clear, cogent, and convincing" evidence to overturn it. The Board says the evidence that actually moves the needle includes:

• Comparable sales from the correct assessment year — for a 2026 assessment appeal, that means sales that closed in 2025, not this year or last.
• An independent professional appraisal of your property.
• Contractor bids or repair estimates documenting defects the county's valuation doesn't reflect.
• Photographs showing conditions that reduce value (foundation issues, deferred maintenance, view obstruction, etc.), attached to notated sheets.
• Documentation of easements or other restrictions affecting usable value.

Older sales and general "my neighbor's taxes are lower" arguments carry little weight on their own.

How to File: Step by Step

1. Do the informal check first (see above) — it's free and often resolves the issue faster than a hearing.
2. Get the correct petition form. Pierce County uses Washington State Department of Revenue-approved petitions, with separate versions for residential property, commercial property, manufactured/mobile homes, and personal property. Forms are posted on the Board of Equalization's page on piercecountywa.gov.
3. Fill it out completely, including your correct 10-digit tax parcel number. Vague or incomplete answers can get a petition rejected.
4. Attach your evidence, or plan to submit it separately — evidence must be received at least 21 business days before your scheduled hearing. Documents must be single-sided and no larger than 8½" × 14"; photos should be attached to notated sheets.
5. Sign and submit the petition to the Board of Equalization — by mail or in person at 2401 South 35th Street, Room 176, Tacoma, WA 98409. Do not send it to the Assessor-Treasurer; that's a different office with a different mailing address, and a petition filed there isn't filed with the Board.
6. There is no fee to file.
7. What happens next: An appraiser may reach out to inspect the property, and many cases settle by agreement before a hearing is needed. If not, you'll receive the Assessor-Treasurer's written response at least 21 business days before your hearing date. Hearings are informal — you can represent yourself, both sides can testify and respond to each other's evidence, or you can ask the Board to decide on written evidence alone without attending. The Board must notify you of its decision within 45 days of the hearing. A reduction takes effect immediately; an increase doesn't take effect for 30 days, giving you time to appeal further to the state Board of Tax Appeals.

Property Tax Rates and Levies

Washington's constitution caps the combined regular property tax levy at 1% of true and fair value — $10 per $1,000 of assessed value — across all overlapping taxing districts on a parcel. On top of that, state law separately limits the combined levy of "senior and junior" taxing districts (the county, cities, most special districts) to $5.90 per $1,000, with certain levies like school and port districts falling outside that specific cap.

Because Pierce County has 121 separate taxing districts — cities, fire districts, school districts, ports, and more — your actual combined rate depends entirely on which overlapping districts your parcel sits in. There is no single county-wide rate that applies to every property. The Assessor-Treasurer publishes an official "Average Tax Rates" table by city and town each year; check your own parcel's exact combined rate through the parcel search tool linked below rather than assuming a county average applies to you.

When Property Taxes Are Due — This Is NOT the Appeal Deadline

This is worth repeating because the two dates get confused constantly: the July 1 appeal deadline has nothing to do with when your tax bill is due.

Pierce County property taxes are billed annually and can be paid in two installments:

• April 30 — first-half payment due (or the full amount if your total tax is $50 or less)
• October 31 — second-half payment due

If you miss a payment deadline, interest starts accruing May 1 — 0.75% per month on residential properties (1–4 units, tax year 2023 and later) or 1% per month on other property types, plus a 3% penalty added June 1 and an additional 8% penalty added December 1 on delinquent amounts (11% maximum combined penalty). None of this affects your right to appeal your valuation, and appealing your value does not pause or excuse a tax payment that's already due — pay first, appeal separately.

Exemptions: Seniors, People with Disabilities, and Veterans

Washington's Senior Citizen and People with Disabilities property tax exemption can reduce or freeze the taxable value of your primary residence. In Pierce County, to qualify you generally need to meet all of the following:

• Age 61 or older as of December 31 of the assessment year (or age 57+ as the surviving spouse/domestic partner of a former participant), or be unable to work due to a disability at any age, or be a veteran with an 80%+ VA service-connected disability rating or receiving 100% VA compensation (note: Pierce County's published guidance indicates this veteran threshold is set to drop to a 40% minimum rating starting with the 2027 tax year).
• Own and occupy the home as your principal residence more than six months of the year (temporary absences for medical care are allowed). Mobile home owners can qualify even without owning the underlying land. Vacation homes don't qualify.
• Household income at or below $64,000/year (this was the published threshold for both the 2024 and 2025 qualifying years) — including a co-owner's or spouse's income, and a prorated share of other household members' contributions to expenses.

Washington also runs a related property tax deferral program (RCW 84.38) for seniors and people with disabilities whose income is too high for the exemption but who still need help — it defers a portion of taxes as a lien against the property rather than eliminating them. Contact the Assessor-Treasurer's exemptions unit for current deferral income limits, since they differ from the exemption thresholds.

Applying: You can apply online, by mail, or in person at the Assessor-Treasurer's office (2401 S. 35th St., Room 142, Tacoma, WA 98409; (253) 798-2169). Once approved, the exemption doesn't need to be renewed every year — Pierce County re-verifies eligibility on a cycle of at least once every six years, and will mail you a renewal notice when it's due. You must proactively report changes in income, ownership, or occupancy that could affect your eligibility.

Look Up Your Property Record

Before you appeal, pull your official record card to see exactly what the county has on file — square footage, year built, land value versus improvement value, and comparable sales the Assessor used. Use the county's Assessor-Treasurer Information Portal (ATIP) parcel search at atip.piercecountywa.gov to look up any Pierce County parcel by address or parcel number.
