Property Tax Exemptions and Relief Programs for Seattle Homeowners
As King County property values — and property tax bills — have climbed in recent years, many homeowners don't realize meaningful relief programs already exist for those who qualify. Seniors, people with disabilities, and disabled veterans may be eligible for significant property tax reductions, sometimes cutting a bill by more than half. TC Wu breaks down the current programs and how to find out if you qualify.
Property Tax Relief Programs Available in King County
Four programs worth checking your eligibility for.
Senior & Disabled Persons Exemption
Washington's senior and disabled exemption is one of the most generous in the country. Homeowners age 61 or older — or of any age if retired due to disability — who own and occupy their home as a primary residence may qualify for a reduction based on household income relative to county-specific thresholds. In King County for 2026, those thresholds are set at $60,000, $72,000, and $84,000, with lower income generally producing a larger reduction — potentially a 60% cut in assessed value, a 35% cut, or a frozen assessed value depending on which tier you fall into.
Disabled Veterans Exemption
Veterans with a service-connected disability rating of at least 80%, or those receiving VA compensation at the 100% rate for a service-connected disability, may qualify for the same exemption benefits as the senior/disabled program, based on income and disability rating. Surviving spouses or domestic partners of qualifying veterans may also be eligible to continue receiving the benefit.
Senior Property Tax Deferral
If your income is too high to qualify for the exemption but you're still age 60 or older (or retired due to disability), Washington's deferral program lets you postpone paying property taxes rather than reduce them. Deferred amounts accrue simple interest — currently around 5% annually — and become a lien on the property, repaid when the home is eventually sold or transferred.
Limited Income Deferral Program
A separate deferral program is available to homeowners of any age who have owned their property for at least five years and meet income requirements, without a senior or disability requirement. This program allows deferral of the second-half property tax installment after the first half has been paid, offering flexibility for homeowners facing a temporary income squeeze regardless of age.
"I'm always surprised how many longtime homeowners don't realize they might qualify for real property tax relief. These programs exist specifically to help people stay in homes they've owned for decades — it's worth five minutes to check your eligibility."— TC Wu, WPI Real Estate | Top Seattle Realtor
King County Senior/Disabled Exemption Tiers (2026)
Reduction generally depends on which income tier you fall into — verify exact figures with the King County Assessor.
| Income Tier | 2026 Threshold | Typical Benefit |
|---|---|---|
| Tier 1 (lowest income) | Up to $60,000 | ~60% reduction in assessed value |
| Tier 2 | $60,000 – $72,000 | ~35% reduction in assessed value |
| Tier 3 | $72,000 – $84,000 | Assessed value frozen |
| Above Tier 3 | Above $84,000 | May qualify for deferral instead |
How to Apply for Property Tax Relief
Four steps to check your eligibility and apply.
Check Your Eligibility With the King County Assessor
Review the current income thresholds and eligibility criteria directly on the King County Assessor's website, since figures are updated periodically.
Gather Your Income and Ownership Documentation
Have your prior year's income documentation and proof of primary residence ready — most applications ask for this upfront.
Apply Online for Faster Processing
King County recommends applying online rather than by paper application for the fastest turnaround on exemption and deferral requests.
Recertify Annually and Report Changes
Once approved, notify the Assessor's Office of any changes to your income or occupancy status, and be prepared for annual recertification requirements.
