Updated August 3, 2026. Quick answer: Washington runs a exemption and deferral for senior homeowners. The programme type is what matters most: it decides whether your bill is reduced, held flat, refunded based on income, or merely postponed. And postponed is the one to look at twice — a deferral is a debt against the house, not a discount.
What Washington offers
- Exemption — age 61+; income limit county-specific: the greater of the prior published threshold or 70% of county median household income (2024-2026 published table). Senior Citizen and People with Disabilities Property Tax Exemption. Reduces or exempts property tax for qualifying owners 61+ occupying the home as a primary residence more than six months a year; administered by county assessors.
- Deferral — age 60+; income limit county-specific deferral threshold, generally higher than the exemption threshold (current). Property Tax Deferral Program for Senior Citizens and People with Disabilities. The State of Washington pays the property taxes on the homeowner’s behalf for the primary residence, up to five acres; requires enough home equity to secure the state’s interest.
The deferral trap
Washington lets qualifying seniors defer property tax. A deferral is not relief in the ordinary sense: the tax is still owed, it accumulates, and it is typically secured against the home and repayable when the owner dies, sells or moves out. Confirmed from dor.wa.gov: the deferred amount accrues 5% simple interest and becomes a lien in favour of the State of Washington, repayable when the home is sold, the homeowner dies, or it stops being the primary residence. For a homeowner whose plan is to leave the house to their children that matters enormously — the heirs inherit the debt with the property. It can still be the right choice for someone who needs cash flow now and has no heir depending on the equity. How deferral liens work.

Two things to check before you count on it
- Thresholds move. Age and income limits are reset by legislatures and are frequently indexed. Every figure above carries the year we confirmed it; confirm the current one before you budget around it.
- Your county may add its own. Statewide programmes are the floor. Counties and municipalities frequently run additional exemptions, and those are where a lot of real money sits.
