Property Tax in Snohomish County, 2026

A calculator and field guide for Everett-area homeowners — and for anyone considering a move to Snohomish County — including Washington's 100% assessment ratio, the regular vs. excess levy structure, Initiative 747's 1% annual cap on regular levy revenue growth, and the income-tested Senior Citizens and Disabled Persons Property Tax Exemption with assessed-value freeze.

Snohomish County, home to Everett and 833k Washingtonians, operates under Washington State's distinctive levy-based property tax system. Washington uses 100% assessment ratio (assessed at true and fair market value) and total tax combines state school + local school + county + city + special districts (typically expressed as dollars per $1,000 of AV). Initiative 747 (passed by voters in 2001) caps regular levy revenue growth at 1% per year per district.

How the bill is built

Washington's property tax calculation has two main steps. Step 1: Assessed Value. The Snohomish County Assessor reassesses property annually at true and fair market value. Step 2: Apply combined rate. Total rate combines all overlapping districts (state school + local schools + county + city + EMS + library + fire + park + flood control + cemetery, depending on location). Snohomish's combined rate is approximately 9.20 per $1,000 of AV. Tax = (AV × combined rate) / 1,000. Snohomish's effective rate of 0.92% reflects this calculation.

Initiative 747's 1% revenue cap creates structural rate stability. When property values rise, the rate decreases automatically so total levy revenue grows by no more than 1% per year per district (excluding new construction and voter-approved excess levies). This has produced unusually stable effective rates over time — long-term WA homeowners typically see modest, predictable bill growth even during housing bubbles. The cap excludes voter-approved school maintenance and operations levies, which is why school district rates often dominate the combined bill.

Washington has no state income tax — but compensates with high sales tax. Washington is one of nine US states with no state income tax (alongside TX, FL, TN, NV, SD, WY, AK, NH). The state-level sales tax is 6.5%, with local add-ons typically bringing combined sales tax to 8.5-10.5% depending on the locality (King County combined: ~10.1%, among the highest in the United States). For high-income residents the no-income-tax structure typically offsets the high sales tax substantially; for lower-income residents the trade-off is less favorable.

Senior Citizens and Disabled Persons Property Tax Exemption is income-tested. Income limits (2026): under $30,000 = full exemption from regular levies + AV freeze; $30K-$35K = 65% reduction + freeze; $35K-$45K = 35% reduction + freeze. Apply with the Snohomish Assessor office. The same program applies to disabled veterans — Washington does NOT have a separate veteran-specific full exemption, which puts WA among the less-generous states for disabled veterans relative to TX, FL, MI, NJ, PA, OH, or VA.

As of April 26, 2026 · From Snohomish County Assessor.

Note: Snohomish County, anchored by Everett (the largest city in the county and home to Boeing's Everett Factory — the largest building in the world by volume, where the 747, 767, 777, and 787 Dreamliner aircraft are assembled), is the third-most-populous county in Washington. The county includes the affluent Edmonds and Mukilteo Puget Sound waterfront, the rapidly-growing Bothell/Mill Creek bedroom suburbs (extending into King County), and the rural Cascade foothills around Stevens Pass.

Note: Snohomish County effective property tax rates run approximately 0.92% — slightly higher than King (0.85%) but lower than Pierce (1.05%). Washington 100% assessment ratio applies. Initiative 747's 1% annual revenue cap applies statewide. Median home values (~$638K) are meaningfully lower than King County, making Snohomish the canonical "north of Seattle" relocation choice for buyers priced out of the King County market.

Note: For relocation buyers: Snohomish is the second Puget Sound suburb option — generally cheaper than King but with longer Seattle commutes (typically 30-60 min via I-5 or I-405). The Lynnwood/Mill Creek/Bothell corridor in southern Snohomish County hosts substantial tech and biotech employment (T-Mobile US is headquartered in Bellevue but has substantial Snohomish operations). The Boeing Everett Factory drives a substantial aerospace engineering employment base.

Senior/disabled exemption and excess levies for 2026

Washington's homeowner tax relief is concentrated in a single income-tested Senior Citizens and Disabled Persons Property Tax Exemption (covering both seniors AND disabled veterans). Initiative 747's 1% revenue cap creates structural rate stability for ALL property owners regardless of exemption status.

Senior Citizens and Disabled Persons Property Tax Exemption

Washington's exemption combines a partial reduction of regular property taxes with a freeze on assessed value at the time of qualification. Income limits (2026) are tiered:

Income under $30,000: Full exemption from regular levies + AV freeze
Income $30,000-$35,000: 65% reduction in regular levies + AV freeze
Income $35,000-$45,000: 35% reduction in regular levies + AV freeze

Eligibility: must be 61+ OR disabled OR a disabled veteran with 80%+ service-connected disability. Apply with the Snohomish Assessor office. Once qualified, the AV freeze locks in your assessed value as of the qualification year — even if market values rise substantially, your assessed value (and tax base) remains constant. The exemption applies to regular levies only; voter-approved excess levies (typically school M&O) are still owed.

Property Tax Deferral Program (seniors 60+)

Washington offers a Property Tax Deferral Program separate from the senior exemption — eligible seniors 60+ with income under ~$57K can defer property tax payments (with state-paid interest) until the property is sold or transferred. The deferred amount becomes a lien on the property. This is particularly valuable for cash-poor / asset-rich seniors who want to remain in their homes.

Excess Levies (school M&O)

Washington's regular levies are capped at 1% annual revenue growth per district under Initiative 747 (2001). However, voter-approved excess levies — primarily school maintenance and operations levies — are exempt from the 1% cap. Excess levies typically run 2-4 year terms and require 60% voter approval. School excess levies often dominate the combined tax bill (typically 30-50% of the total) — when these levies expire and are renewed (or fail), bills can change significantly. Watch for ballot measures.

Appealing your assessment

Washington's appeal process runs through the County Board of Equalization (BOE). Homeowners file a Petition for Review with the BOE within 60 days of the change of value notice (or by July 1, whichever is later). The BOE holds hearings — homeowners can present comparable sales, recent appraisals, or independent appraiser testimony. BOE decisions can be appealed to the Washington State Board of Tax Appeals within 30 days; from there to Superior Court. Most Washington counties reassess annually under the State Department of Revenue's revaluation cycle.

Frequently asked questions

When are Washington property taxes due?

Washington property taxes are due in two installments: April 30 (first half) and October 31 (second half). Bills under $50 must be paid in full by April 30. Late payments incur 1% per month interest plus a 3% delinquency penalty after May 31 (first half) or December 1 (second half). Most Washington homeowners pay through escrow via their mortgage servicer. The Snohomish Assessor office handles collection.

What is Initiative 747 and how does it limit my taxes?

Initiative 747 (passed by Washington voters in 2001) caps regular levy revenue growth at 1% per year per district. When property values rise (sometimes substantially), the rate decreases automatically so total revenue grows by no more than 1%. The cap excludes new construction (so growing districts can collect more) and voter-approved excess levies (primarily school maintenance and operations levies, which require 60% voter approval). I-747 has produced unusually stable effective rates over time — long-term Washington homeowners typically see modest, predictable bill growth even during housing bubbles. The Washington Supreme Court initially struck down I-747 in 2007, but the legislature re-enacted it in a 2007 special session.

How does Washington's no-state-income-tax structure affect total tax burden?

Washington is one of nine US states with no state income tax (alongside TX, FL, TN, NV, SD, WY, AK, NH). The state-level sales tax is 6.5%, with local add-ons typically bringing combined sales tax to 8.5-10.5% depending on locality. For high-income residents, the no-income-tax structure typically produces meaningful net savings — especially for buyers relocating from California (which has top marginal income tax of 13.3%) or New York (10.9%). For lower-income residents, the high sales tax shifts more burden to consumption-based taxation. Property tax effective rates in Washington (~0.8-1.1%) are moderate by national standards.

How do I apply for the Senior/Disabled Persons Exemption?

The Senior Citizens and Disabled Persons Property Tax Exemption is income-tested with three tiers (2026): under $30K = full exemption from regular levies + AV freeze; $30K-$35K = 65% reduction + freeze; $35K-$45K = 35% reduction + freeze. Eligibility: must be 61+ OR disabled OR a disabled veteran with 80%+ service-connected disability. Apply with the Snohomish Assessor office. Once qualified, the AV freeze locks in your assessed value as of the qualification year. The exemption applies to regular levies only; voter-approved excess levies are still owed. Disabled veterans use this same program — Washington does not have a separate veteran-specific full exemption.

How do I appeal my Washington assessment?

File a Petition for Review with your County Board of Equalization (BOE) within 60 days of the change of value notice (or by July 1, whichever is later). The BOE holds hearings — homeowners can present comparable sales, recent appraisals, or independent appraiser testimony. BOE decisions can be appealed to the Washington State Board of Tax Appeals within 30 days; from there to Superior Court. Most Washington counties reassess annually under the State Department of Revenue's revaluation cycle.

About Snohomish County

Beyond the property tax — a few things you might not know about the place.

Weird fact

Boeing's Everett Factory in Snohomish County is **the largest building in the world by volume** — at 472 million cubic feet (13,400,000 cubic meters), the building is so large it has its own indoor weather patterns and required custom climate control to prevent indoor cloud formation during early operation. The factory was originally built in 1967 to assemble the Boeing 747 and currently hosts assembly of the 767, 777, and 787 Dreamliner programs. The building is so large that the Walt Disneyland park (the original 1955 California park) could fit inside with substantial parking-lot space remaining.

Hometown hero

Henry M. Jackson

The longtime US Senator from Washington (1912-1983, served 1953-1983) was born and raised in Everett, Snohomish County. "Scoop" Jackson was one of the most-influential US senators of the 20th century — a defense hawk, environmentalist, and architect of the National Environmental Policy Act (NEPA, 1970). The Henry M. Jackson Federal Building in Seattle and Henry M. Jackson High School in Mill Creek are named in his honor. Jackson ran for the Democratic presidential nomination in 1972 and 1976 (losing both bids).

Biggest annual event

Mukilteo Lighthouse Festival + Stevens Pass winter sports

The Mukilteo Lighthouse Festival (annual, September at the historic Mukilteo Light Station) is one of the largest community festivals in north Puget Sound, drawing 50,000+ attendees with the iconic lighthouse tours, parade, and waterfront events. Stevens Pass (in eastern Snohomish County, approximately 90 minutes from Seattle) is one of the most-popular ski destinations in the Cascades — the Stevens Pass Ski Area sees ~400,000 skier visits annually.
