What Are Property Taxes Like in Sammamish?
Sammamish property taxes are one of the first costs buyers ask us to explain. The rate is modest by national standards, but the city's high home values make the dollar amount substantial. Understanding how those two pieces fit together helps you budget accurately and avoid surprises after closing.
We are The Van Pelt Group at John L. Scott, a multi-generational Sammamish-area team with more than 30 years on the Eastside. We work with buyers and sellers across Klahanie, Pine Lake, Sahalee, and the wider Sammamish Plateau. This guide covers how Sammamish property taxes are calculated, what the rate actually is, and what you can expect to pay at different price points.
How Are Sammamish Property Taxes Calculated?
Sammamish property taxes are set by King County, not the city alone. The County Assessor assigns each home an assessed value, and that value is multiplied by a combined levy rate in dollars per $1,000 of assessed value to produce your annual bill.
The levy rate is a stack of separate charges. The largest funds public schools, with more for the county, the city, fire and emergency services, libraries, and voter-approved measures. State law limits how much each district can grow its regular levy yearly, keeping the rate fairly stable, though new levies can nudge it up. Because Sammamish spans both the Lake Washington and Issaquah school districts, the exact rate depends on which side of SE 8th Street a home sits on, so two houses on one street can carry different bills. We confirm the current assessed value and levy code before you write an offer.
What Is the Property Tax Rate in Sammamish?
The effective Sammamish property tax rate, meaning total taxes paid divided by market value, generally falls between 0.85 percent and 0.95 percent. That sits below the national median rate of about 1.02 percent, so on a percentage basis Sammamish is not a high-tax location.
What catches buyers off guard is the dollar amount, not the rate. A national median tax bill is close to $2,400 a year, while a median-priced Sammamish home generates several times that. Rates shift modestly year to year as levies are approved or expire, so treat any single number as an estimate.
What Will You Pay on a Sammamish Home?
The bands below apply a rate near 0.9 percent to common price points. Your actual bill depends on the assessed value, levy code, and tax year.
Entry-level Sammamish homes near $1.0 million: roughly $8,500 to $9,500 a year
Townhomes, smaller plateau homes, and older properties like those in Sunny Hills anchor the lower end. Annual taxes here run in the high four figures, the city's most attainable rung.
Median Sammamish homes near $1.57 million: roughly $13,000 to $15,000 a year
This band covers much of Klahanie, Beaver Lake, and the central plateau, where most move-up buyers land. A low-to-mid five-figure bill is the realistic baseline for a typical single-family home in Sammamish.
Luxury Sammamish homes above $2.5 million: roughly $21,000 to $24,000 and up
Estate homes in Sahalee, waterfront on Pine Lake, and acreage in East Sammamish carry the highest bills. Plan for property taxes well into the five figures as a fixed annual cost.

How Sammamish Property Taxes Compare
On a rate basis, Sammamish property taxes look much like the rest of King County, since the county sets assessments and most of the levy structure. What separates one city from another is home value, so a similarly priced home in Bellevue or Redmond carries a broadly comparable bill. Washington also has no personal state income tax, which shifts more of the funding burden onto property and sales taxes. For the high-income families who make up much of the Sammamish buyer pool, that often offsets a meaningful share of the property tax. Our guide to whether Sammamish is worth the price compared to Bellevue looks at the wider value question.
Property Taxes, HOA Fees, and Total Cost in Sammamish
Property taxes are only one line in the carrying cost of a Sammamish home. Many of the city's most popular neighborhoods are master-planned communities with homeowner associations. In Klahanie, Sahalee, and similar areas, HOA fees commonly run from about $50 to $300 or more per month depending on amenities such as trails, pools, and maintenance.
Relief is available for some owners. King County offers a property tax exemption and deferral program for qualifying seniors aged 61 and older and for people with disabilities, subject to income limits, and the savings on a high-value home can be significant. We walk every client through taxes, HOA dues, insurance, and upkeep early, so the monthly picture is clear before closing.
Frequently Asked Questions
How much are property taxes on a median Sammamish home?
A median-priced Sammamish home near $1.57 million typically generates a property tax bill of roughly $13,000 to $15,000 a year. That reflects an effective rate near 0.85 percent to 0.95 percent applied to a high assessed value. Your exact figure depends on the assessed value, the levy code, and the tax year.
Is the property tax rate in Sammamish high?
On a percentage basis, no. The effective rate of roughly 0.85 percent to 0.95 percent sits below the national median of about 1.02 percent. What makes the bills large is the city's high home values, not the rate. Combined with Washington having no state income tax, the overall tax profile can be favorable for many high-income households.
Who sets Sammamish property taxes?
The King County Assessor sets each home's assessed value, and the bill is that value multiplied by a combined levy rate in dollars per $1,000 of assessed value. The levy funds schools, the county, the city, fire and emergency services, libraries, and voter-approved measures. Because Sammamish spans two school districts, the rate can vary slightly by location.
Does Washington have a state income tax that affects Sammamish buyers?
Washington has no personal state income tax, so property and sales taxes carry more of the local funding load than in states with an income tax. For the high-earning households that make up much of the Sammamish market, the absence of an income tax often offsets a meaningful portion of the property tax, which is part of the city's long-term appeal.
Are there property tax breaks for seniors in Sammamish?
Yes. King County offers a property tax exemption and deferral program for qualifying homeowners aged 61 and older and for people with disabilities, subject to income limits. On a high-value Sammamish home the savings can be substantial. Eligible owners apply through the King County Assessor's office.
Do Sammamish neighborhoods charge HOA fees on top of property taxes?
Many do. Master-planned communities such as Klahanie and Sahalee are managed by homeowner associations, with monthly dues commonly running from about $50 to $300 or more depending on amenities. Those fees are separate from property taxes and belong in your monthly budget, and we confirm the current dues for any home before you make an offer.
