Property tax in Washington is one of the most commonly misunderstood parts of homeownership here, largely because the system is budget-based rather than rate-based. Understanding that distinction explains almost everything else.
The short answer
Washington's average effective property tax rate is approximately 0.85 to 1.0 percent of assessed value, which places it near the middle of all states.
On a $900,000 home, expect roughly $7,600 to $9,000 per year, depending on county and local levy districts.
The rate is not set in advance. Taxing districts adopt a budget, and the rate is calculated by dividing that budget across the total assessed value in the district. This is why your rate can fall when values rise.
How the system actually works
Most states set a rate and multiply it by your assessed value. Washington does the reverse.
- Taxing districts adopt budgets. Your county, city, school district, fire district, library district, and others each determine how much revenue they need.
- The county assessor determines total assessed value across the district.
- The rate is calculated by dividing the budget by total assessed value.
- Your bill is your assessed value multiplied by the combined rate of every district you sit in.
The practical consequence: if every home in your district rises 15 percent in value, the district still collects roughly the same total revenue. The rate simply drops. Your bill only rises meaningfully if your property rose more than the district average, or if voters approved new levies.
The one percent limit. Under Washington law, most taxing districts may increase their regular levy revenue by no more than 1 percent per year, plus revenue from new construction. Voter-approved levies — school bonds, emergency medical services, fire districts — sit outside this cap. This is why school levy elections drive noticeable changes to your bill.
What your bill is composed of
A typical Washington property tax bill includes:
| Component | Approximate share |
|---|---|
| Local school district levies | 40 – 55% |
| State school levy | 15 – 22% |
| County general levy | 8 – 15% |
| City or town levy | 8 – 18% |
| Fire and EMS districts | 4 – 10% |
| Library, port, hospital, other | 2 – 8% |
Schools dominate. In most Washington jurisdictions, education funding accounts for well over half of the property tax bill.
Rates by county
Effective rates vary meaningfully across the state. Approximate 2026 figures:
| County | Approx. effective rate | Notes |
|---|---|---|
| King | 0.85 – 0.95% | High values, moderate rate |
| Snohomish | 0.90 – 1.05% | |
| Pierce | 1.05 – 1.25% | Among the higher rates in the region |
| Kitsap | 0.85 – 1.00% | |
| Thurston | 0.95 – 1.10% | |
| Spokane | 0.95 – 1.15% | |
| Clark | 0.90 – 1.05% | |
| San Juan | 0.55 – 0.70% | Among the lowest in the state |
Rates also vary within counties by city and levy district. Two homes of identical value a mile apart can carry different bills if they sit in different school or fire districts.
Estimated annual tax on a $900,000 home:
- King County: roughly $7,600 – $8,600
- Snohomish County: roughly $8,100 – $9,400
- Pierce County: roughly $9,400 – $11,300
Assessment: how your value is determined
County assessors are required to revalue all property annually and to physically inspect each property at least once every six years.
Assessment is based on true and fair market value as of January 1 of the assessment year. Taxes based on that assessment are paid the following year. Your 2026 tax bill reflects your January 1, 2025 assessed value.
Assessors use mass appraisal — statistical models applied across neighborhoods using recent sales, property characteristics, and market trends. This is accurate in aggregate and occasionally wrong for individual properties, which is what the appeal process exists to correct.
You will receive a Change of Value Notice when your assessment changes. This is not a bill. It is your notice, and it starts the clock on your right to appeal.
How to appeal your assessment
If you believe your assessed value exceeds true market value, you can appeal.
The deadline is strict. Petitions must be filed with your county Board of Equalization by July 1 of the assessment year, or within 60 days of the date your Change of Value Notice was mailed, whichever is later. Counties may extend to 60 days by resolution. Missing the deadline forfeits the appeal for that year.
What actually wins an appeal:
- Recent comparable sales showing lower values for genuinely similar properties
- A recent independent appraisal
- Documented condition problems — foundation issues, roof failure, water damage
- Factual errors in the assessor's record, such as incorrect square footage, bedroom count, or lot size
- Evidence the property cannot be used as the assessor assumed, such as a zoning or easement restriction
What does not win an appeal:
- The bill is too high
- Taxes went up more than you expected
- A neighbor pays less
- You cannot afford it
The question before the board is narrow: does the assessed value exceed true market value as of the assessment date? Nothing else is relevant.
The process: file the petition, gather evidence, and present to the Board of Equalization. Decisions may be appealed to the Washington State Board of Tax Appeals. Many appeals resolve informally — contacting the assessor's office directly to point out a factual error often corrects it without a formal hearing.
Exemptions and deferrals
Washington offers several meaningful programs. These are underused, and eligible homeowners frequently do not know they qualify.
Senior citizen and disabled persons exemption
The most significant program available.
Eligibility:
- Age 61 or older by December 31 of the assessment year, or retired from regular employment due to disability, or a veteran with an 80 percent or greater service-connected disability
- The property must be your principal residence, occupied at least six months per year
- Household disposable income must fall below the county threshold
Income thresholds are county-specific and indexed to local median income. In King County the top qualifying tier sits above $80,000 in most recent years. Thresholds are updated periodically — verify current figures with your county assessor.
The benefit is tiered. Depending on which income band you fall into, the exemption may freeze your assessed value at the year you first qualified, exempt you from all voter-approved excess levies, and exempt a portion of your regular levies. At the lowest income tier the reduction can exceed half the bill.
Applications go to your county assessor. Once approved, most counties require periodic renewal rather than annual reapplication.
Property tax deferral for senior citizens and disabled persons
Allows qualifying homeowners to defer payment. The state pays the tax and records a lien against the property, repaid with interest when the home is sold or transferred. This is not forgiveness — it is a postponement — but it can allow someone to remain in a home they could not otherwise afford.
Disabled veterans
Veterans with a service-connected disability rating of 80 percent or higher, or those receiving compensation at the 100 percent rate, may qualify under the senior and disabled persons exemption program. Income limits still apply.
Home improvement exemption
Physical improvements to a single-family home may be exempt from resulting property tax increases for three assessment years, up to 30 percent of the pre-improvement assessed value. You must apply before the improvement is completed. This is one of the most commonly missed programs in the state — homeowners renovate, then learn about it afterward when it is too late to claim.
Open space, farm, and timber classifications
Land used for agriculture, timber, or designated open space may be assessed at current use value rather than highest and best use, substantially reducing the tax. Removing land from the classification triggers back taxes plus interest and a penalty.
Nonprofit exemptions
Property owned and used by qualifying nonprofit organizations may be exempt. Applications go through the Washington State Department of Revenue.
Payment deadlines
Property tax in Washington is billed annually and payable in two installments.
- First half: due April 30
- Second half: due October 31
If the total owed is $50 or less, the full amount is due April 30.
Late payments incur interest at 1 percent per month from the delinquency date, plus penalties: 3 percent added June 1 and an additional 8 percent added December 1 on amounts still outstanding.
Most homeowners with a mortgage pay through an escrow account, and the servicer remits on their behalf. If you own free and clear, or if your loan does not escrow, you are responsible for paying the county directly. Counties mail statements in February, but non-receipt does not excuse a late payment.
Property tax when you buy or sell
At closing, taxes are prorated. The seller pays for the portion of the year they owned the property; the buyer pays from the closing date forward. This is handled by escrow.
Do not confuse property tax with the real estate excise tax. Washington imposes a separate excise tax (REET) on the sale of real property, paid by the seller, on a graduated scale:
| Portion of sale price | State rate |
|---|---|
| Up to $525,000 | 1.10% |
| $525,001 – $1,525,000 | 1.28% |
| $1,525,001 – $3,025,000 | 2.75% |
| Above $3,025,000 | 3.00% |
Local jurisdictions add their own REET, commonly 0.25 to 0.50 percent. On a $1,000,000 sale, total excise tax typically lands near $12,000 to $14,000.
A common buyer surprise: the seller's tax bill may have reflected a senior exemption or a below-market assessment. Once the property sells, that exemption disappears and the assessment resets toward the sale price. Buyers should estimate their tax based on the purchase price, not the seller's prior bill. This catches people every year.
Common questions
Does Washington have a property tax exemption for primary residences? There is no general homestead exemption reducing taxes for all owner-occupants. Washington's homestead statute protects home equity from certain creditors but does not reduce property tax. Relief comes through the senior, disabled, and veteran programs.
Why did my assessed value jump but my tax stay flat? Because Washington's system is budget-based. If values across your district rose similarly, the rate falls to keep district revenue near the 1 percent growth limit.
Why did my tax rise more than my neighbors'? Either your property appreciated more than the district average, or you sit in a levy district where voters approved a new bond or levy.
Can I pay monthly? Counties bill in two installments. Monthly payment generally happens through a mortgage escrow account rather than directly with the county.
Is property tax deductible on my federal return? State and local taxes, including property tax, are deductible subject to the federal SALT cap. Consult a tax professional for your situation.
What happens if I do not pay? Interest and penalties accrue. Washington counties may begin foreclosure proceedings on property with taxes delinquent for three years.
Where to verify your specific numbers
Property tax is administered at the county level. For your exact assessed value, levy rates, exemption eligibility, and payment status, contact your county assessor and treasurer directly. King, Snohomish, and Pierce counties all provide online parcel lookup tools showing current assessment, levy breakdown, and payment history.
