Pierce County property taxes are billed by the Assessor-Treasurer’s office based on your property’s assessed market value multiplied by the combined levy rates of every taxing district your parcel sits in. For 2026, the bill is split in half: the first installment is due April 30 and the second is due November 2, and you can also pay the full year by April 30.1Pierce County. 2026 Property Taxes Arriving in Your Mailbox Soon Missing the April deadline makes the entire year’s balance delinquent and starts interest running on all of it.
How Your Bill Is Calculated
Every taxable property in the county is valued at 100 percent of fair market value as of January 1 each year.2Washington State Legislature. RCW 84.40.030 – Manner of Assessment, Appraisal, Market Value, Physical Inspection Fair market value is what a willing buyer would pay a willing seller in an open transaction. The assessor gets there by looking at recent sales of comparable properties and applying statistical models to reflect shifts in the local market. If prices in your neighborhood have climbed, your assessed value will likely climb with them even when nothing about your home has changed.
Your parcel sits inside several overlapping taxing districts: the county, your city or town, a school district, a fire district, and often a library or park district. Each district sets its budget and divides that budget by the total assessed value inside its boundaries to produce a levy rate, expressed as dollars per $1,000 of assessed value. Your annual tax is the sum of every applicable levy rate multiplied by your assessed value. At a combined rate of $12 per $1,000, a home assessed at $400,000 owes $4,800 for the year. Rates vary widely across the county because the combination of districts is different in every location.
Payment Deadlines and Late Interest
The first-half deadline is the one that matters most. If your April 30 payment doesn’t arrive on time, the entire year’s tax is treated as delinquent, not just the first half, and interest accrues on the full unpaid amount. For residential property with four units or fewer, the rate is 9 percent per year. For larger residential and all commercial property, it’s 12 percent per year.3Washington Department of Revenue. Legislative Changes to Delinquent Property Taxes On a $5,000 residential bill, a few months of delay easily runs into the hundreds of dollars.
The second-half deadline of November 2 works the same way, but only the second half is subject to interest at that point if the first half was paid on time.
How to Pay
You can pay by mail, online, or through a mortgage escrow account. Mailed checks made payable to Pierce County go to Pierce County Finance, P.O. Box 11621, Tacoma, WA 98411-6621, and should include the payment stub or, failing that, the parcel number written on the check.4Pierce County, WA. Tax Bills and Payments For mail, the postmark date controls, not the day the county opens the envelope.
Online payments carry processing fees that vary a lot depending on how you pay. Credit cards run 2.35 percent of the amount, debit cards cost a flat $3.50, and e-checks cost $0.50 per payment.5Pierce County, WA. Pay by Credit Card On a $3,000 payment, a credit card fee alone is over $70, so e-check is the cheapest electronic option by a wide margin.
If your mortgage lender collects taxes through an escrow account, they’ll remit the payment on your behalf. Don’t assume it happened. Confirm with your lender each cycle that the payment cleared, because the county still holds you responsible if it didn’t.
Your 10-digit parcel number is the key to looking up what you owe and applying a payment to the right account. You’ll find it on your annual tax statement, on the Assessor-Treasurer Information Portal, or through the county’s online parcel lookup.6Pierce County, WA. Parcel and Property Information
Exemptions for Seniors, Disabled Residents, and Veterans
Washington’s property tax exemption program can cut a qualifying homeowner’s bill substantially. You may qualify if you’re at least 61 by December 31 of the filing year, or retired due to a disability, or a veteran with a VA disability rating combined at 80 percent or higher, or with a total disability rating for a service-connected condition.7Washington State Legislature. RCW 84.36.381 – Exemptions, Qualifications The home has to be your primary residence and you have to own it.
How much you save depends on your household income, which counts both taxable and nontaxable income for you, your spouse or domestic partner, and any co-owner living with you. Pierce County uses three income tiers:8Pierce County, WA. Senior Citizens or People with Disabilities
- $55,001 to $64,000: exempt from excess (voter-approved) levies and Part 2 of the state school levy.
- $46,001 to $55,000: exempt from excess levies, Part 2 of the state school levy, and regular levies on $50,000 or 35 percent of assessed value, whichever is greater, capped at $70,000 of taxable value.
- $46,000 or less: exempt from excess levies, Part 2 of the state school levy, and regular levies on $60,000 or 60 percent of assessed value, whichever is greater.
You apply through the Pierce County Assessor-Treasurer’s office with supporting documents like tax returns and, for disability-based claims, medical records or a VA rating letter. The exemption takes effect the year after you file.7Washington State Legislature. RCW 84.36.381 – Exemptions, Qualifications
Deferral If You Can’t Pay
Seniors, disabled residents, and qualifying veterans who can’t afford their taxes but want to stay current can defer payments under the state deferral program. A deferral is not forgiveness. The state records a lien on your home and collects the deferred taxes plus 5 percent annual interest when you sell, move out, or die. The lien can grow to as much as 80 percent of your equity. For someone on a fixed income facing delinquency, it buys time; it isn’t free. The Assessor-Treasurer’s office handles eligibility and applications.
Home Improvement Exemption
If you improve a single-family home, the value added by the work can be exempt from property tax for three assessment years after it’s finished. The improvement must add no more than 30 percent of the home’s pre-improvement value, and you can only claim this exemption once every five years.9Washington State Legislature. RCW 84.36.400 – Improvements to Single-Family Dwellings A $20,000 kitchen remodel on a $300,000 home qualifies. A $150,000 addition on that same home does not.
Appealing Your Assessed Value
If you think your assessed value is higher than what your property would actually sell for, you can petition the Pierce County Board of Equalization. File within 60 days of the date your value change notice was mailed, or by July 1 of the assessment year, whichever is later.10Pierce County, WA. Board of Equalization
The Board is a quasi-judicial body and the hearing runs closer to a trial than a conversation. The assessor’s value is presumed correct, and you have to overcome it with clear, cogent, and convincing evidence.11Washington State Legislature. RCW 84.48.010 – Equalization of Assessments That’s a higher bar than “more likely than not.” Effective evidence looks like a recent independent appraisal, comparable sales showing lower prices for similar homes, or repair estimates showing property conditions the assessor didn’t account for.
The Board can only rule on whether the assessed value exceeds fair market value. It won’t hear complaints about the tax amount itself, levy rates, financial hardship, or how your increase compares to a neighbor’s.10Pierce County, WA. Board of Equalization Appeals without solid comparable sales or an appraisal are the ones that lose. Line up the evidence before you file.
If You Don’t Pay
Unpaid property tax doesn’t go away. Interest keeps accruing every year the balance is unpaid, and after three years of delinquency the county treasurer must issue a certificate of delinquency and start foreclosure.12Washington State Legislature. Chapter 84.64 RCW – Lien and Sale of Property for Delinquent Taxes Once the county files the case, you have 30 days to either pay the full balance with back taxes, interest, and costs, or appear in court to contest the action.
If you’re falling behind, the deferral program or a partial-payment arrangement through the Assessor-Treasurer’s office can keep the account out of foreclosure. Reach out before the certificate of delinquency issues. Options shrink quickly after that.
Business Personal Property
Property tax in Pierce County isn’t limited to real estate. Businesses have to report taxable personal property each year: furniture, fixtures, machinery, equipment, supplies not held for sale, and leased equipment. Intangibles like patents, copyrights, and trademarks are exempt. The personal property listing is due to the assessor by April 30 each year.13Pierce County, WA. Property Assessment If you don’t file, the assessor estimates the value for you, which rarely comes out in the taxpayer’s favor.
