Loan Property Tax in Washington
Washington homeowners pay an average effective property tax rate of 0.75% — ranked #30 of 50 states — and a median annual bill of $4,729, about 1.5× the national median bill. Here is how the tax is computed in Washington, what it costs on real home values, and where the exemptions hide.

Sources: Effective rates: Tax Foundation, Facts & Figures 2026 (mean property tax paid on owner-occupied homes as a share of value, calendar year 2024). Median annual bills: U.S. Census Bureau, 2024 American Community Survey 1-year estimates (median real estate taxes paid, owner-occupied households). Effective rates fold in each state's assessment ratios and typical exemptions, which is what makes them comparable across states — your county's actual rate can sit well above or below the state average.
How property tax is computed in Washington
The mechanics everywhere follow the same skeleton: tax = (assessed value − exemptions) × combined local rate, where the combined rate stacks county, municipal, school and special-district levies. What differs by state is how "assessed value" relates to market value, how fast it may rise, and which exemptions exist.
Washington limits regular property tax levy growth to 1% a year plus new construction, so when home values jump, rates usually fall rather than bills rising in proportion. There is no state income tax; the property tax and sales tax carry most of the load.
The effective-rate shortcut used across this guide — market value × 0.75% — skips the local machinery and lands on what Washington homeowners actually pay as a share of value, which is the right way to compare Washington with anywhere else.
Worked example: the median Washington bill
The median Washington homeowner pays $4,729 a year. Working backwards from the 0.75% effective rate, that bill corresponds to a home worth roughly $630,533 (an approximation — the rate is an average across all owner-occupied homes, the bill a median). Check the same rate at three price points: a $250,000 home pays about $1,875, a $400,000 home about $3,000, and a $600,000 home about $4,500.
Exemptions move real money: every $25,000 of taxable value exempted saves $188 a year at Washington's rate. If your home is your primary residence, confirm your homestead status with your county assessor before assuming the bill is final — exemptions rarely apply themselves.
Lowering a Washington property tax bill
Appeal the value, not the rate. Rates are set by budgets; values are set by assessors, and assessors make mistakes — wrong square footage, an extra bathroom, a condition grade your home does not deserve. Comparable sales of similar nearby homes are the standard evidence, and appeal windows are short, commonly 30 to 60 days after the assessment notice.
Claim every exemption. Homestead exemptions for a primary residence are the big one in most states; many states add senior, veteran, disability or low-income relief, and some cap how fast assessed values may rise for long-time owners. None of it arrives automatically — each program has an application and a deadline at your county assessor or tax office.
Watch the escrow, not just the bill. If your lender escrows taxes, the monthly line on a median Washington bill runs about $460 once the permitted two-month cushion is included. A sudden escrow jump usually means the underlying bill rose or last year's account ran short — the assessor's notice, not the lender, is where the fix starts.
Washington property tax questions
What is the average property tax rate in Washington?
0.75% of home value on an effective basis — ranked #30 of the 50 states — per the Tax Foundation's analysis of Census data. Effective means tax actually paid divided by value, so it already reflects Washington's assessment rules and typical exemptions.
How much is property tax on a $400,000 home in Washington?
About $3,000 a year at the state average rate. Your county can differ substantially: high-service suburbs run above the average, rural areas below it. The calculator linked above takes your county's exact rate if you have it from a tax bill.
Why don't Washington's rate rank and typical bill tell the same story?
Because bills are rate × value, and the two rankings measure different things. Home values do a lot of the work here — a modest rate on expensive homes still writes large checks. The median bill here is $4,729 — about 1.5× the national median bill. The rate tells you the tax climate; the bill tells you the typical check actually written, and home values move it as much as rates do.
When are Washington property taxes due?
Due dates are set locally in Washington, commonly in one or two installments a year; if your mortgage escrows the tax, your lender pays on schedule from your escrow account. Check your county treasurer for exact dates and any early-payment discount — a few jurisdictions still offer one.
