How Property Taxes Work in Sequim, WA
Washington runs a property tax system that surprises buyers coming from states with an assessed-value growth cap. There's no Proposition 13-style freeze and no Oregon Measure 50-style 3% cap on taxable value -- Washington generally taxes property at its actual current market value, reassessed regularly, while capping how fast each taxing district's total levy revenue can grow. Understanding that distinction, and Clallam County's specific assessment cycle, is the difference between a real Sequim tax estimate and a guess.
The 1% Levy Limit: A Cap on District Revenue Growth, Not on Your Bill
Washington's constitution limits the aggregate regular property tax levy on an individual parcel to 1% of its true and fair value -- a figure commonly shorthanded as the '$10 limit,' since property tax rates are typically expressed as dollars per $1,000 of assessed value, and 1% of value equals $10 per $1,000. It's a common point of confusion, so it's worth stating plainly: this 1% figure caps how much a taxing district's total levy revenue can increase from one year to the next -- generally no more than 1% annually, absent a voter-approved 'levy lid lift' or the district drawing on banked capacity -- not a cap on the rate applied to any individual property. An individual home's assessed value can rise or fall by far more than 1% in a given year as the market moves, and its tax bill moves with that assessed value even while the underlying district-wide levy revenue growth stays capped near 1%.
This is structurally different from Oregon's Measure 50, just across the strait, which caps how fast an individual property's own taxable assessed value can grow (3% a year), regardless of what the district's total levy needs. Washington's approach means a Sequim property's assessed value should track its actual market value fairly closely over time, since the county reassesses regularly rather than letting a capped assessed value drift further and further below real market value the way a long-held Oregon or California property's can. The practical upshot: a Sequim buyer generally shouldn't expect the kind of large gap between assessed value and market value, or the kind of 'reassessment on sale' shock, that a California buyer moving from a Proposition 13 state might anticipate.
Clallam County: Annual Revaluation, Six-Year Physical Inspection
Clallam County is classified by the Washington Department of Revenue as an annual revaluation county, meaning every property in the county gets a new assessed value calculation each year -- as opposed to counties on a longer revaluation cycle, where values might only be formally updated every two, four, or six years. Layered underneath that annual revaluation is a separate, state-mandated requirement that every parcel undergo a physical, on-site inspection at least once every six years; Clallam County implements this by physically inspecting roughly one-sixth of the county's parcels each year on a rolling basis, while monitoring sales activity across the rest of the county using computer-assisted mass appraisal in the years between physical inspections.
For a Sequim buyer, this means the assessed value on a property's most recent tax statement should be a reasonably current reflection of market conditions -- assuming no unusual local sales-activity distortions -- rather than a stale, years-old figure. It also means a property that receives a major renovation, addition, or new construction in a given year can see its assessed value jump meaningfully at the next annual revaluation cycle, reflecting the improvement, distinct from the general market-driven movement every property experiences.
What the Actual Rate Is -- and Why It Varies by Address
Clallam County's own primary (general-fund) property tax rate was cited at $0.95 per $1,000 of assessed value for 2025 -- but that figure alone materially understates most actual tax bills, because a typical Sequim parcel sits within several overlapping taxing districts simultaneously: the county's general fund, the City of Sequim (for in-city parcels), Sequim School District 323 (or the relevant district for a specific address), and potentially a fire district, port district, library district, or other special district, each levying its own separate rate. One property-data aggregator, Ownwell, estimates Sequim's effective combined property tax rate somewhere around 0.75% to 0.87% of assessed value -- a reasonable directional planning figure, but not a substitute for the county's own current combined rate for a specific tax code area.
The City of Sequim's own FY2026 budget process illustrates how these pieces move: the City Council voted 6-1 in November 2025 to apply the full state-allowed 1% levy increase for the city's own portion of the bill, projected to raise about $19,000 from that increase alone, with total city property-tax revenue expected to rise roughly $50,000 once new construction and prior-year refunds are included -- on top of a roughly $51.6 million FY2026 city budget described locally as the largest in Sequim's history. That city-level levy is only one component of a Sequim property owner's full combined bill; the county, school district, and any special districts each set their own rates separately, on their own schedules.
Senior, Disabled, and Other Exemption Programs
Washington offers a statewide property tax exemption and deferral program for qualifying senior citizens and disabled homeowners, administered at the county level, that can reduce or partially exempt a primary residence from regular property tax levies based on age (typically 61 or older), disability status, and income thresholds that are periodically adjusted. Clallam County's own Assessor's Office administers applications for this program locally. This page does not have a confirmed current income threshold or exemption percentage for the program as it applies in Clallam County for the current tax year, since these figures are adjusted periodically at the state level and should be confirmed directly rather than assumed from a prior year's published threshold.
A retiree specifically drawn to Sequim's demographic profile -- median age above 62, a large 65-and-older population share -- should ask the Clallam County Assessor's Office directly, before or shortly after a purchase, whether they qualify for this exemption program and what documentation is required, since it can meaningfully reduce an otherwise full-market-value tax bill for an eligible household.
Paying the Bill: Practical Logistics
Washington property tax bills are generally payable in two installments each year, with an April deadline for the first half and an October deadline for the second half, though a property owner may also pay the full year's bill at the April deadline if preferred -- this page treats this as a general statewide pattern rather than a confirmed Clallam-County-specific schedule, and recommends confirming exact current due dates directly with the Clallam County Treasurer's Office. Most mortgage lenders escrow property tax as part of a monthly payment; an owner without an escrow arrangement is responsible for paying the county directly according to its published schedule, and Washington counties, like most states, can impose real penalties for late payment.
A Sequim buyer should ask a seller's agent or the county Assessor's Office directly for the property's current assessed value and most recent combined tax bill before closing, rather than relying on an estimate embedded in a listing sheet -- since Clallam County's annual revaluation means last year's figure may already be somewhat out of date by the time a sale closes.
What This Page Does Not Know
This page does not have a single confirmed combined property tax rate (county plus city plus school plus any special district) applicable to every Sequim address, since Washington's tax-code-area system genuinely varies parcel to parcel. It also does not have a confirmed current income threshold or benefit level for Washington's senior/disabled property tax exemption program as applied in Clallam County for the current tax year, or a confirmed exact property tax payment due-date schedule specific to Clallam County.
Before making a purchase decision, confirm the exact current combined tax rate and bill for a specific parcel, and current senior/disabled exemption eligibility, directly with the Clallam County Assessor's Office and Treasurer's Office.
