Pierce County tax assessor: assessments, appeals, and exemptions explained

Last updated 2026-07-09

What does the Pierce County Assessor-Treasurer actually do?

One elected office in Pierce County does two jobs most counties split. It values every taxable parcel, and it bills and collects the taxes on those values. The office is held by Mike Lonergan, who took office in 2019. You deal with this single office for almost everything: assessment disputes, exemption applications, payment plans, and public records requests for comparable sales.

Pierce County covers roughly 1,676 square miles and holds about 340,000 taxable parcels, from Tacoma condos to timberland near Mount Rainier ^[1]. That scale forces the office to use mass appraisal models instead of hand appraisals for most homes. The model pulls recent sales, adjusts for property characteristics, and spits out a value. It works fine on average. It also produces real errors on individual houses, and that is exactly why an appeal process exists.

Washington law, RCW 84.40.030, requires all property to be valued at 100 percent of its true and fair market value as of January 1 of the assessment year ^[2]. True and fair value means what a willing buyer would pay a willing seller, neither one under pressure to close. Your tax bill is that assessed value multiplied by the combined levy rates from the state, county, city, school district, and every other taxing district layered on your parcel.

How does Pierce County assess your property's value?

The office revalues all property every year, because Washington law requires it ^[2]. A physical inspection happens on a rotating cycle, generally once every six years. Between those visits, the computer-assisted mass appraisal (CAMA) model updates your value annually using recent comparable sales.

Here is what the model looks at for a single-family home: living area square footage, lot size, year built, construction quality grade, bathroom count, garage type, view, and recent sales of similar homes in your neighborhood. The office sorts properties into market areas and neighborhood codes. If your neighborhood code sweeps in a stretch of homes that sold higher than your street justifies, the model can overvalue your house without a single human looking at it.

Commercial and income properties get three approaches. Appraisers use the sales comparison approach (what similar properties sold for), the income approach (what a buyer would pay based on the rental income stream), and the cost approach (replacement cost of the improvements minus depreciation). Homes lean almost entirely on sales comparison.

Business personal property, meaning equipment, machinery, and leasehold improvements, is assessed on its own track. Businesses must file a personal property listing with the office by April 30 each year ^[11]. Skip it and you eat a 25 percent penalty on the assessed value.

One detail pays off fast. Pierce County publishes neighborhood sales data and the exact property characteristics it has on file through its online parcel search. Look up your parcel. Check whether the square footage, bedroom count, and quality grade match your actual house. A wrong record is the easiest win in any appeal, and you can spot it in ten minutes.

When are assessment notices mailed, and when is the appeal deadline?

Washington law requires assessment notices to be mailed by June 1 of the year before the tax year they affect ^[2]. In practice, Pierce County usually mails residential notices in spring, often April through May. The notice shows your assessed value for the coming tax year.

Your deadline to appeal to the Pierce County Board of Equalization (BOE) is 60 days from the date printed on the notice, or July 1 of the assessment year, whichever is later ^[3]. This is a hard statutory deadline under RCW 84.48.010 ^[10]. Miss it and you cannot appeal that year. You start over with next year's notice.

Bought your house and got a value change notice triggered by the sale? The same 60-day window runs from that notice date.

Milestone	Typical Date	Legal Authority
Assessment notices mailed	April-May (assessment year)	RCW 84.40.045
BOE appeal deadline	60 days from notice, no later than July 1	RCW 84.48.010
BOE hearing scheduled	Within 180 days of petition receipt	WAC 458-14-066
Tax first installment due	April 30	RCW 84.56.020
Tax second installment due	October 31	RCW 84.56.020
Personal property listing due	April 30	RCW 84.40.020

Miss the BOE window and you have one narrow safety valve: a petition for Department of Revenue review, or in limited cases a Superior Court appeal on legal grounds. Both routes are harder and slower. File on time.

Tax payments run on their own clock. Your tax bill reflects the assessed value from the prior year. Taxes come due in two installments, the first half by April 30 and the second half by October 31 ^[4]. Paying under protest does nothing for your appeal rights. You need a separate BOE petition.

How do you file a Pierce County property tax appeal?

The formal appeal goes to the Pierce County Board of Equalization, an independent quasi-judicial body separate from the Assessor-Treasurer's office. You file a Petition for Review of Real Property Assessment, available on the BOE's website or at the county offices ^[3].

The petition asks for your parcel number, the assessed value on your notice, the value you think is correct, and a short statement of why. No legal brief required. One sentence does the job: "The assessed value of $580,000 exceeds market value; comparable sales from early 2024 show a range of $490,000 to $520,000." That gets your petition accepted.

After you file, the BOE schedules a hearing within 180 days ^[3]. Hearings run informal, maybe 15 to 30 minutes. You present your evidence, an Assessor-Treasurer representative presents theirs, the three-member board asks questions and issues a written decision, usually within a few weeks.

What evidence actually moves the BOE:

• Comparable sales: Three to six closed sales of similar homes within roughly a mile and within the prior year, pulled from the county's own parcel search or a free MLS printout. The board weighs sales most heavily when they sit geographically close, match in size and age, and closed within six months of January 1 of the assessment year.
• A recent appraisal: If you had one done for a refinance or purchase near the assessment date, bring it. Appraisals carry weight because they use the same methodology the board trusts.
• Your property's condition: Photos of deferred maintenance, structural problems, or flood zone limits the mass appraisal model never sees.
• The assessor's property record card: Wrong square footage or an inflated quality grade can support a reduction on its own.

You do not need an attorney or a property tax consultant. The process is built for owners representing themselves. If you want a system for pulling comps and writing the argument, TaxFightBack's DIY appeal kit walks the same method no matter which county you're in.

Lose at the BOE and the next step is the Washington State Board of Tax Appeals, then Superior Court. Most residential cases end at the BOE.

What exemptions can reduce your Pierce County property tax bill?

Washington has several exemptions that cut what you owe, and Pierce County runs all of them. Applications go to the Assessor-Treasurer's office. None of them apply on their own. You have to file.

Senior Citizen and Disabled Person Exemption (the big one) This program, authorized under RCW 84.36.381, exempts part of your assessed value and in some cases freezes it entirely ^[12]. To qualify you must be 61 or older (or disabled), own and occupy the home as your primary residence, and have combined household income below the threshold the state sets each year ^[5]. For tax year 2024 the thresholds were:

Household Income	Benefit
$0 to $40,447	Assessed value frozen; exempt from excess and special levies
$40,448 to $49,435	Assessed value frozen; exempt from excess levies
$49,436 to $58,423	Partial reduction in assessed value

These numbers adjust yearly ^[5]. The application deadline is December 31 of the year before the tax year you want it applied. File early. The office gets backed up.

Disabled Veteran Exemption Veterans with a 100 percent service-connected disability rating from the VA qualify for an exemption on up to $80,000 of assessed value under RCW 84.36.379 ^[6]. The surviving spouse of a qualifying veteran may also qualify. Income limits apply.

Home Improvement Exemption Add living space or make repairs to accommodate a disabled person in your household, and you can apply to exclude those improvements from the assessed value for up to ten years under RCW 84.36.400.

Current Use Programs (Open Space, Farm, and Timber) Own agricultural land, open space, or timberland that qualifies under RCW 84.34 or RCW 84.33, and the land gets assessed at its current use value instead of its highest-and-best-use market value ^[13]. On rural parcels the difference is huge. Convert the land to a higher-value use later and you pay a withdrawal penalty.

One thing people miss: if your situation changes, including income rising over the threshold, you are supposed to tell the office.

How can I look up my Pierce County assessment and property record online?

The office runs a public parcel search at assessor.piercecountywa.gov. Search by address, parcel number, or owner name ^[1]. The parcel page shows your current assessed value, the split between land and improvements, tax history, payment status, and the property characteristics on file.

Read the characteristics section closely. It lists year built, living area square footage, bathroom count, the quality grade (a letter or number score reflecting construction quality), and the effective year built, which the model uses instead of actual year if the assessor believes a major renovation modernized the property. Any of those wrong, and you have a clean, documentable reason to appeal.

Comparable sales sit in the parcel search too, and the office publishes sales files for download. The county GIS maps let you draw a radius and pull every sale within a set distance and time window. That is the same data the assessor's model runs on, so it is where your own comp analysis should start.

Payment questions land at the same office: current balance, payment plan options, installment due dates. In many counties the treasurer is a separate shop. Not here ^[4].

What is the Pierce County Board of Equalization, and how is it different from the assessor?

The Board of Equalization is an independent three-member board appointed by the Pierce County Council. It is not part of the Assessor-Treasurer's office. Its job is to hear appeals from owners who disagree with the assessor's valuation and issue binding decisions.

The BOE sets no policy. It does not change the assessment rolls on its own, and it does not touch exemption denials, which follow a separate appeal path. It rules on value disputes, nothing else.

Board members do not have to be appraisers or attorneys, though they get training on Washington's assessment standards. Hearings are open to the public. The board issues written decisions, and either party (you or the assessor) can appeal them to the Washington State Board of Tax Appeals.

Pierce County's BOE typically handles several hundred to over a thousand petitions a year, and the exact count moves around. Statewide, roughly half of residential petitions win some reduction, based on historical Department of Revenue data, though Pierce County's own rate swings year to year. Nobody publishes clean county-level numbers on a regular schedule. The best proxy is the state's annual statistical report on assessment and equalization ^[7].

One practical limit: the board can only reduce your value down to market value. It cannot go below what the evidence supports, and it cannot grant exemptions. Want an exemption? File that application with the Assessor-Treasurer separately.

How does Pierce County compare to other Washington counties on property tax rates?

Washington has no state income tax, so property taxes carry more of the local funding load than in most states. The state levy alone runs about $2.70 per $1,000 of assessed value for most property, though it stepped down from a temporarily higher rate and gets recalculated every year ^[7].

Your total rate in Pierce County is the sum of every taxing district whose lines cross your parcel: the state, the county general fund, the road levy, your city or town if you have one, the school district (often carrying both a maintenance-and-operations levy and a capital levy), plus fire, library, port, and hospital districts. The combined rate swings hard depending on where you sit.

A rough comparison across Washington's most populous counties, using 2023 levy data from the Department of Revenue:

County	Approximate Average Effective Rate (per $1,000 AV)
King	$8.50 - $10.00
Pierce	$9.50 - $12.00
Snohomish	$8.00 - $11.00
Spokane	$10.00 - $14.00
Clark	$9.00 - $12.00

These are ranges because the rate hinges on which districts cover your specific parcel ^[7]. The wide band inside Pierce County alone shows the gap between, say, a Tacoma parcel stacked with a city levy and overlapping districts versus a rural parcel with far fewer.

Here is the practical read. A $50,000 cut in assessed value in a high-rate district saves you maybe $500 to $600 a year. In a lower-rate district, closer to $400. Over five years that is real money, and it keeps compounding forward.

What if I own property in Pike County or a Georgia county with a similar assessor structure?

Landed here researching a different office? Here is a quick orientation on how these systems differ by state.

The Pike County tax assessor in Georgia (Pike County, GA) works under a completely different legal framework. Georgia counties use a Board of Tax Assessors model: a five-member appointed board oversees assessment, and the chief appraiser runs the daily valuation work. The Pike County GA tax assessor assesses property at 40 percent of fair market value, not 100 percent like Washington, because Georgia uses an assessment ratio system under OCGA 48-5-7 ^[8]. Georgia appeals go first to the county Board of Assessors for informal review, then to the Board of Equalization, then to superior court or arbitration.

The Walton County GA tax assessor, sometimes searched as just the Walton County tax assessor, runs on the same Georgia framework: 40 percent assessment ratio, annual notices, a 45-day appeal window from the notice date (tighter than Pierce County's 60 days), and a three-level appeal ladder ^[9]. For the Georgia BOE process in detail, the Gwinnett County tax assessor and Coweta County tax assessor guides cover it.

The Walton County tax assessor office could also mean Florida's Walton County, where the Property Appraiser assesses at 100 percent of just value under Florida law. That is a third system again. Florida uses a separate Value Adjustment Board for appeals, a 25-day petition window, and a special magistrate hearing.

The point holds across all of them. Assessor structure, assessment ratios, deadlines, and appeal paths change sharply by state. Confirm which state you're dealing with before you trust any procedural detail.

What are the most common mistakes homeowners make in Pierce County appeals?

Missing the 60-day deadline is the most common mistake and the most final one. The BOE has essentially no power to accept a late petition.

Second most common: filing with the wrong office. Appeals go to the Board of Equalization. Not the Assessor-Treasurer. Not the county council. Not the state Department of Revenue. Filing your complaint in the wrong place does not stop the clock.

Third: bringing list-price comparables instead of closed sales. Active listings show what sellers hope to get. The assessor's model, the BOE, and every appraisal standard use closed sales only. Active listings get politely dismissed.

Fourth: arguing fairness instead of value. "My neighbor's house is assessed lower than mine" wins nothing on its own, because the assessor values each property at market value, and a neighbor's underassessment does not make your overassessment correct. To use the neighbor at all, you have to show the house is genuinely comparable and that the market data supports a lower value for both.

Fifth: waiting for the tax bill. The assessment notice and the tax bill are two different documents. The notice triggers the appeal deadline, and it arrives months before the bill. Plenty of homeowners open the tax bill in spring, see taxes went up, and only then discover the appeal window for that year closed the previous summer.

Want to build a real comp analysis and appeal letter without handing a firm a cut of your savings? A structured approach like the TaxFightBack appeal kit organizes the same evidence the BOE expects, at a flat cost instead of a percentage of whatever reduction you win.

How do I contact the Pierce County Assessor-Treasurer's office?

The office sits at 2401 South 35th Street, Room 142, Tacoma, WA 98409. The phone is (253) 798-6111. It is open Monday through Friday, 8:30 a.m. to 4:30 p.m. ^[1]

For online services, the parcel search, payment portal, exemption applications, and appeal forms all live at assessor.piercecountywa.gov.

Board of Equalization petitions go to the BOE's own clerk. Contact details are on the Pierce County website under the Board of Equalization section. The BOE is at 930 Tacoma Avenue South, Room 1046, Tacoma, WA 98402 ^[3].

Got a specific question about how your value was calculated? The Assessor-Treasurer's office will schedule an informal conference with an appraiser before you file a formal BOE petition. This informal review does not extend your appeal deadline, but it often clears up discrepancies fast, especially errors in the property record. Ask for it the day your notice arrives.

To see how other large counties handle taxpayer contact and informal review, the processes at Bexar County, Cook County, and Los Angeles County each run their own way and are worth a look if you own property in more than one state.

Frequently asked questions

What is the appeal deadline for Pierce County property tax assessments?

You have 60 days from the date printed on your assessment notice, or July 1 of the assessment year, whichever is later, to file a petition with the Pierce County Board of Equalization. RCW 84.48.010 sets this deadline and it is not flexible. Miss it and you cannot appeal that assessment year; you wait for next year's notice.

How do I find my Pierce County assessed value online?

Go to assessor.piercecountywa.gov and use the parcel search. Enter your address or parcel number. The results page shows your current assessed value, the land-to-improvement breakdown, prior year values, tax payment history, and the property characteristics the model used to value your home. Check the characteristics record carefully for square footage or quality grade errors.

Who is the Pierce County Assessor-Treasurer?

Mike Lonergan has served as Pierce County Assessor-Treasurer since 2019. The office is elected and combines the assessor and treasurer functions that many other Washington counties split between two offices. It handles property valuation, tax billing, collection, payment plans, and exemption administration.

Does Pierce County assess property at full market value or a fraction?

Pierce County, like every Washington county, must assess at 100 percent of true and fair market value as of January 1 of the assessment year, per RCW 84.40.030. Washington does not use an assessment ratio like some states. If your property is assessed at $500,000, that figure is supposed to represent full market value, not a percentage of it.

Who qualifies for the senior exemption in Pierce County?

You must be 61 or older (or legally disabled), own and occupy the home as your primary residence, and have combined household income below the state threshold, which was $58,423 for the highest tier in tax year 2024. The benefit ranges from a partial value reduction to a full value freeze and levy exemption depending on income. Apply at the Assessor-Treasurer's office by December 31.

Can I appeal my Pierce County property taxes without hiring a lawyer or consultant?

Yes. The Pierce County Board of Equalization is built for owners representing themselves. You file a one-page petition, gather three to six comparable closed sales showing a lower market value, and present them at a 15 to 30-minute hearing. No legal training required. A contingency-fee firm takes a slice of any reduction you win; doing it yourself keeps every dollar of the savings.

What happens at a Pierce County Board of Equalization hearing?

The hearing is informal and usually lasts 15 to 30 minutes. You present your evidence, usually comparable sales or an appraisal. An Assessor-Treasurer representative presents the county's valuation support. The three-member board asks questions and issues a written decision within a few weeks. You do not need to call witnesses or follow courtroom procedure.

How is the Pierce County tax assessor different from Georgia county assessors like Pike County or Walton County?

Georgia counties, including the Pike County GA tax assessor and Walton County GA tax assessor, run a Board of Tax Assessors model and assess property at 40 percent of fair market value under OCGA 48-5-7. Pierce County assesses at 100 percent under Washington law. Georgia's appeal window is 45 days from the notice, shorter than Pierce County's 60 days. Ratios, procedures, and deadlines differ significantly between states.

When are Pierce County property taxes due?

Property taxes in Pierce County come due in two installments. The first half is due April 30 and the second half is due October 31, set by RCW 84.56.020. If the total tax owed is under $50, it is due in full by April 30. Late payments accrue interest and penalties, so contact the Assessor-Treasurer's office about payment plans if you cannot pay on time.

What if the Pierce County Board of Equalization rules against me?

You can appeal the BOE's decision to the Washington State Board of Tax Appeals, a state-level administrative body. If the BTA also rules against you, the final option is Pierce County Superior Court. Each level has its own filing deadline running from the prior decision. Most residential owners stop at the BOE; the BTA and court process adds cost and time.

What is the Pierce County personal property tax filing deadline for businesses?

Businesses that own taxable personal property, including equipment, machinery, and leasehold improvements, must file a personal property listing with the Pierce County Assessor-Treasurer by April 30 each year under RCW 84.40.020. Missing the deadline triggers a 25 percent penalty on the assessed value. The listing form is on the Assessor-Treasurer's website.

Can I get a disabled veteran property tax exemption in Pierce County?

Yes. Veterans with a 100 percent service-connected disability rating from the VA can exempt up to $80,000 of assessed value under RCW 84.36.379. Surviving spouses of qualifying veterans may also be eligible. Income limits apply. Apply at the Assessor-Treasurer's office with documentation of your VA disability rating and proof of ownership and occupancy.

How often does Pierce County physically inspect properties for assessment purposes?

Pierce County inspects residential parcels on a rotating cycle, generally once every six years. Between inspections, the computer-assisted mass appraisal model updates values annually using recent comparable sales. Commercial properties may be inspected more often. If significant improvements or changes have occurred, you can request a review, and the assessor may schedule an inspection outside the normal cycle.
