Property tax relief in Washington: the senior and disabled exemption at 61

A Washington homeowner who is 61 or older by the end of the year, or unable to work because of a disability, or a veteran with an 80% or higher service-connected rating, and whose household income is under the county’s limit, can apply to the county assessor for the Senior Citizens and People with Disabilities Property Tax Exemption. Every qualifying household gets the home’s taxable value frozen at the first year of eligibility and the state school levy and all voter-approved excess levies removed from the bill. Households in the lower two income tiers also get a slice of value exempted from the regular levies: for taxes collected in 2027, the greater of $80,000 or 80% of value for the lowest tier, with no cap, and the greater of $70,000 or 45% of value, capped at $200,000 of value, for the middle tier. The income limits for 2027 are 60%, 70% and 80% of the county’s median household income, up from 50%, 60% and 70% for 2026, under ESSB 6162. The application goes to the assessor by December 31 of the assessment year, and the Department of Revenue reports that 118,039 households received the exemption on 2024 taxes, averaging $3,181 each.

Everything else a homeowner in another state might expect is absent. There is no exemption for simply living in the house. Assessed value tracks the market every year, and a doubling of home prices doubles the assessed value. The 1% limit on levy growth belongs to the taxing districts, not to the owner. Property tax is levied by the county and dozens of local districts and billed by the county treasurer in two halves, April 30 and October 31. For most Washington homeowners the only relief is the general one: a well-run appeal of the assessed value to the county board of equalization when the assessor’s number is wrong.

Who qualifies

The Department’s brochure sets out four doors. Age: 61 or older by December 31 of the assessment year, which is the year before the taxes are paid. Surviving spouse: 57 or older and the surviving spouse or registered domestic partner of someone who had the exemption when they died. Disability: unable to work because of a disability, with no age requirement. Veterans: a service-connected disability evaluation of 80% or more, or compensation at the 100% rate for a service-connected disability. Only one owner of a jointly owned home has to meet one of these; the spouse or co-owner need not.

The home must be owned by December 31 of the assessment year, in fee, under a contract purchase, or as a life estate, including a lease for life. A home held in a revocable trust generally qualifies if the applicant is the beneficiary who lives there (verify); a cooperative share and some government-owned housing can also qualify. The applicant must live in the home more than six months of the year, and a stay in a hospital, nursing home, assisted living or a relative’s home does not break that, provided the house is not rented out. A vacation home never qualifies. The exemption covers the residence, one accessory dwelling unit and up to one acre of land, or more where zoning requires a larger lot.

What counts as income

The test is combined disposable income: the applicant’s, the spouse’s or domestic partner’s, and any co-tenant’s, from every source, whether or not the federal return taxes it. Social Security and Railroad Retirement count in full. Pensions, military pay, most veterans’ benefits, the taxable part of IRA withdrawals, interest, dividends, annuities, and capital gains all count; business and rental income count without a depreciation deduction, and capital losses cannot offset other income. A gain on selling a home that is reinvested in a new one within a year is excluded. Income of a non-owner who lives in the house, an adult child for instance, is not counted, though what they contribute to the household is (verify).

Until the 2026 change the applicant could subtract itemized medical costs: nursing home or assisted living charges, prescriptions, in-home care, Medicare and Medigap premiums, long-term care insurance, and out-of-pocket health plan costs. ESSB 6162 replaces that with a standard deduction of $7,500 for the applicant and $7,500 for a spouse or partner, for taxes collected in 2027 and after. A new deduction of up to $6,000 is allowed for rent from living space on the property that is not a short-term rental, but only for applicants who itemize instead of taking the standard deduction. Combat-related special compensation is excluded altogether.

The three tiers and what each takes off

The limits are percentages of the county’s median household income, recalculated every three years and never allowed to fall below the prior year’s figure. The county dollar amounts are posted at dor.wa.gov/incomethresholds, and the spread is wide: a tier 3 limit in King County is well over twice the limit in a rural eastern county (verify). Which tier a household lands in decides how much comes off.

Under the 2026 rules the exemption from the state school levy covered only Part 2 of the levy; for 2027 the levy returns to a single state school levy at $2.075355 per $1,000 of market value and exemption recipients are fully exempt from it. The “greater of” language matters at the low end: on a $90,000 manufactured home, tier 1 exempts $80,000, nearly the whole value.

The freeze

The least noticed part of the exemption is often the most valuable over time. In the first year a household qualifies, the assessor records the home’s taxable value, and from then on the levies are computed on that frozen figure rather than on each year’s market value, for as long as the household stays eligible. In a county where assessments rose 8% a year through the early 2020s, a freeze set in 2020 is now worth more than the dollar exemptions. The freeze resets if the household falls out of eligibility and later requalifies, and improvements to the house are added at their value (verify).

Applying, renewing, appealing

The application is filed with the county assessor, on the Department’s form or the county’s version of it, with proof of age or disability, proof of ownership, and income documents for the assessment year: the federal return if one was filed, Social Security statements, 1099-Rs, bank interest statements. The deadline is December 31 of the assessment year, the year before the taxes are collected, and assessors may accept late applications. The exemption is not automatic in later years; the assessor sets a renewal schedule and sends a renewal application when one is due, and the household must report changes, a spouse’s death, a move, a rise in income, before then. A denial can be appealed to the county board of equalization, which must receive the appeal by July 1 or within 30 days of the denial notice, whichever is later. Refunds of taxes paid in error can be claimed for up to three prior years, one application per year.

The deferral program

A second program lets a homeowner who is 60 or older, or retired on disability, defer property taxes and special assessments rather than have them forgiven. The state pays the taxes and takes a lien on the house; the deferred amounts plus interest are repaid when the house is sold or the owner dies. The income limit, which was 75% of county median income for 2020 through 2026, rises to 90% for 2027 and after under ESSB 6162, so it reaches households that are over the exemption limits. A separate limited-income deferral for the second half of the year’s taxes, and a grant for widows and widowers of veterans, use the same income definition. Deferral is not free money, but for a house-rich, income-poor household it keeps the home.

Appealing the value

For the homeowner under 61 with ordinary income there is no exemption, and the only lever is the assessed value itself. The assessor mails a change-of-value notice when the value is revised, and the owner has 30 days from the mailing, or until July 1, whichever is later, to petition the county board of equalization; a county may extend the 30 days to as many as 60, and several have. The appeal is about market value as of January 1 of the assessment year, and it is won with comparable sales from that period, not with an argument about the tax. A successful appeal lowers the taxable value for that year only; the assessor values the property again the next year.
