Lilliwaup, WA: Property Tax on Land With No Town Government Behind It
There's no Town of Lilliwaup to send a property tax bill, because there's no Town of Lilliwaup at all -- it's an unincorporated place, and every dollar of property tax collected on a Lilliwaup parcel flows through Mason County government and the special-purpose districts (school, fire, and others) that overlap that specific address. Washington has no state personal income tax, which is part of why property tax, sales tax, and business taxes carry relatively more of the funding load here than in a state that also taxes wages. This page explains that structure honestly and does not print a specific current combined rate or dollar figure -- this research pass could not confirm this year's certified Mason County numbers against a fully-loaded primary source, and the right place to get them is the Mason County Assessor's Office directly.
No Town Hall, No Municipal Levy -- Just County and District Layers
Lilliwaup has never incorporated as a city or town, so there is no municipal government here to set a separate town property tax rate the way Bainbridge Island or a similar incorporated Washington market would. Every Lilliwaup property tax bill is instead built entirely from overlapping special-purpose taxing districts layered onto the same Mason County Assessor-set valuation: Mason County's own general fund levy, the applicable school district's levy and any voter-approved bonds, Mason County Fire District 17 (the all-volunteer department based in Lilliwaup itself, formed in January 1978), and potentially library or other special-district levies depending on the exact parcel location. That's a structurally simpler bill than an incorporated market carries -- one fewer layer -- but not necessarily a cheaper one, since county, school, and fire levies still add up independently of whether a town government exists.
This is the same basic structure as unincorporated Harstine Island elsewhere in Mason County, but the specific district mix differs: Lilliwaup sits inside Fire District 17's coverage area rather than whatever district covers Harstine, and this page did not confirm which specific school district's boundary applies to Lilliwaup parcels (a Pioneer School District reference turned up in general searches but wasn't confirmed as Lilliwaup's actual assigned district) -- a real, disclosed gap rather than an assumed answer.
Washington's Statutory '1% Levy Limit,' Applied the Same Way Here
Washington property tax statewide operates inside a statutory limit commonly called the "1% levy limit" -- per the Washington Department of Revenue's own published guidance, this constrains how much most taxing districts can increase their total regular property tax levy year over year without voter approval of a levy lid lift or a new voted levy. It traces to a series of 1990s statewide ballot measures, including Referendum 47, that reshaped how the state limits property tax growth -- Mason County, Fire District 17, and whichever school district covers a given Lilliwaup parcel are all bound by this same framework.
The practical point for a Lilliwaup buyer is the one that applies everywhere in Washington: the 1% figure limits year-over-year growth in a district's total levy amount -- it is not a cap on an individual parcel's tax rate or bill as a percentage of value, and it's nothing like a fixed assessment-cap system such as California's Prop 13. A specific parcel's assessed value, and therefore its tax bill, can still move meaningfully at reassessment, and voter-approved special levies sit outside that 1% growth limit on the underlying district budget. Confirm current mechanics for a specific levy year directly with the Washington Department of Revenue or the Mason County Assessor's Office.
The Mason County Assessor: The Actual Authority Here
The Mason County Assessor's Office values every Lilliwaup parcel, applies the levy rates certified by that parcel's overlapping taxing districts, and administers Washington's statewide exemption and deferral programs -- and it is the only authoritative source for a specific parcel's current assessed value, levy breakdown, and appeal procedure. Washington state law (RCW 84.40) requires the Assessor to appraise property at 100% of fair market value, with Mason County's own published materials describing assessed values as reflecting market conditions as of January 1 of the prior year, based substantially on that prior year's actual sales.
Mason County publishes its own annual Levy Book and District Listing by Tax Code Area, and its TaxSifter online parcel-search tool lets a buyer look up a specific parcel's assessed value and levy detail directly, rather than relying on a secondhand estimate. This page does not attempt to reproduce a current combined rate, because those rates shift annually with each district's budget and any voter-approved measures -- call the Assessor's Office directly, or use TaxSifter, for the current figure on any specific Lilliwaup parcel.
Exemptions, Deferrals, and the Fire District Layer Specifically
Washington's statewide exemption and deferral programs for seniors, people retired due to disability, and disabled veterans are administered locally by the Mason County Assessor under rules set by the Washington Department of Revenue. Given how heavily the 2019-2023 population estimate for Lilliwaup skews toward residents 65 and older, this is a program worth a direct conversation with the Assessor's Office rather than an assumption either way -- eligibility depends on age, disability status, income, and primary-residence status, specifics only the Assessor's Office or the Department of Revenue can confirm for a given household and tax year.
Mason County Fire District 17's status as an all-volunteer department, formed in January 1978 and based in Lilliwaup itself, is worth noting specifically here because a fire district's own budget and any voter-approved levy directly affects the fire-district line on a Lilliwaup tax bill -- and an all-volunteer department's funding structure and equipment needs can differ meaningfully from a professional, career department's. This page does not have the district's current levy rate; confirm it with the Mason County Assessor or Fire District 17 directly.
The Rate We Won't Guess, and What to Budget Around Instead
In the interest of not printing a figure this page can't stand behind: this page does not state a specific current combined levy rate, a specific dollar-per-$1,000-of-assessed-value figure, or a specific typical annual tax bill for a Lilliwaup home. A property-tax aggregator (Ownwell) cites a Mason County-wide tax-bill range running roughly from a 25th-percentile figure near $1,427 to a 90th-percentile figure near $5,497 -- that's countywide, spanning everything from modest inland Mason County parcels to high-end waterfront, and it is not a Lilliwaup-specific number this page will narrow down further without a primary-source figure to back it up.
What a buyer can reasonably do while budgeting an offer: request the current assessed value and levy breakdown for the specific parcel directly from the Mason County Assessor's Office or via TaxSifter, confirm which fire district and school district actually apply to that exact parcel (Mason County's taxing-district boundaries aren't always intuitive from a highway address alone), and, if age, disability, or income might make a household eligible for an exemption or deferral program, ask the Assessor's Office directly.
What This Means When You Budget a Purchase
None of this is legal or tax advice. Washington's levy-limit statutes, exemption program rules, and each taxing district's certified rates are set by state law, county administration, and local ballot measures, and they change year to year -- a rate quoted by a listing agent or a prior year's tax bill is not a reliable stand-in for the current, parcel-specific figure only the Mason County Assessor's Office can confirm.
Confirm every current figure directly with the Mason County Assessor's Office, Mason County Fire District 17, the Washington State Department of Revenue, and a licensed Washington tax professional or CPA before making a purchase or relying on any number here for a financial decision.

Washington's lack of a state personal income tax, and its resulting reliance on property, sales, and business taxes, is confirmed via the Washington State Department of Revenue's own materials. The statutory "1% property tax levy limit" and its roots in 1990s ballot measures including Referendum 47 (1997) are described in the Department of Revenue's own guidance ("Property tax - How the 1% property tax levy limit works") and Ballotpedia's coverage of that measure. Lilliwaup's unincorporated status is confirmed via Wikipedia's "Lilliwaup, Washington" entry and general Mason County government geography materials.
