How to Appeal a Pierce County Property Assessment
To appeal a Pierce County assessment, file the state petition form with the Board of Equalization by July 1 or within 60 days of the date your value notice was mailed, whichever is later. It is free, and the case turns on comparable sales.
If your assessed value is higher than what your home would have sold for, you can challenge it. The process is free for homeowners, and you do not need an attorney. You do need to meet the deadline and bring the right kind of evidence.
The deadline
The Pierce County Board of Equalization says a petition must be filed within 60 days of the mailing date on your value change notice, or by July 1 of the assessment year, whichever is later.
For 2026 values, the county announced a deadline of August 25, 2026. That window has closed. Value notices go out in late June, so the next chance to appeal opens when your 2027 notice arrives.
Do not wait for the tax bill. The bill comes in February, months after the appeal window for that value has shut.
Step by step
- Read your value notice. Note the mailing date and the assessed value.
- Check the record. Look up your parcel in the county's parcel search and confirm the square footage, bedrooms, and other facts are right.
- Call the Assessor-Treasurer. Ask how the value was set. The number is (253) 798-6111. Some errors get fixed without a hearing.
- Gather evidence. See the next section.
- Complete the petition. Use the Washington Department of Revenue form. The board says letters and other formats will not be accepted. Forms and instructions are on the Residential Property Appeals page.
- File it. Mail or hand-deliver the petition to the Pierce County Board of Equalization, 2401 South 35th Street, Room 176, Tacoma, WA 98409. Email is not accepted. Attach a copy of your value notice.
- Send any added evidence early. The board requires it at least 21 business days before your hearing.
Each petition covers one parcel and needs the 10-digit parcel number.
Evidence that works
The board decides one question: does the assessment exceed 100% of fair market value? Its instructions say the board "will not do research to support an appeal," so the case is yours to make.
| Strong evidence | Why |
|---|---|
| Comparable sales from the correct year | The assessment is as of January 1. For a 2026 value, that means 2025 sales |
| An independent appraisal | A professional opinion of value near the assessment date |
| Contractor estimates | Written costs to cure defects in the building or land |
| Photographs | Condition problems that reduce market value |
| Documents on easements | Recorded limits on how the land can be used |
The best comparable sales look like your home: same neighborhood, similar size and age, sold close to January 1.
Arguments that do not work
The board lists what it will not consider:
- The amount of your tax bill
- The percentage your value increased
- Personal hardship
- What a neighbor's home is assessed at
- Averages
"My taxes went up 14%" is not an argument the board can act on. "Three similar homes on my street sold for $40,000 less than my assessed value last fall" is.
What happens after you file
The board's clerk sends your petition to the Assessor-Treasurer and schedules a hearing. The board is independent of the Assessor's office.
If the board lowers your value, the change takes effect right away. If either side disagrees with the decision, the next level is the Washington State Board of Tax Appeals.
For questions, the board's office is at (253) 798-7415.
Is it worth the effort?
It depends on the gap. Remember what an appeal can and cannot do. It can lower your assessed value. Because of how levies work, a lower value shifts some of your share to other owners. It does not undo a voter-approved levy.
If your value is within a few percent of what the home would have sold for, an appeal is unlikely to change much. If the county has the wrong square footage or missed a serious condition problem, it is worth an afternoon.
Frequently asked questions
What is the deadline to appeal a Pierce County property assessment?
July 1 of the assessment year, or 60 days after the mailing date on your value change notice, whichever is later. For 2026 values the county's deadline was August 25, 2026.
Does it cost anything to appeal?
No. The county describes the appeal to the Board of Equalization as free for homeowners.
What evidence do I need?
Comparable sales from the year before the January 1 assessment date are the strongest evidence. Appraisals, contractor estimates, and photos of condition problems also count.
Can I appeal because my taxes are too high?
No. The board considers only whether the assessed value exceeds market value. It will not consider the tax amount, percentage increases, or hardship.
