ZIP doesn't have ACS data — typically because it's a PO-box-only ZIP, a single-business ZIP, or a small area where the Census suppresses small-sample estimates. Try a nearby ZIP.

Wyoming's effective property-tax rate is among the lowest in the country — around 0.57% of value statewide — for two structural reasons. Residential property is taxed on only 9.5% of its fair market value, and the state's mineral and energy production, assessed at 100% of value, carries a large share of the statewide tax base so that less of the burden falls on homes.
Enter a 5-digit Wyoming ZIP to see its median property tax, median home value, and effective rate from the US Census American Community Survey 2020–2024 vintage, plus how it compares to the Wyoming state and US national medians. The explainer below covers the 9.5% residential assessment ratio, the annual January 1 valuation, the new 25% homeowner exemption that took effect for tax year 2025, and the long-term-homeowner, veterans, and income-based refund programs.
How Wyoming property tax works
Wyoming taxes property on a fraction of its market value, not the full value. Each county's elected assessor values all property at fair market value as of January 1 every year, then applies the statutory assessment ratio: residential property is assessed at 9.5% of fair market value under Wyo. Stat. §39-13-103, industrial property at 11.5%, and mineral gross product at 100%. Your bill is that assessed value multiplied by the combined mill levies of the county, school districts, and any special districts that serve your parcel. A November 2024 constitutional amendment (Amendment A) made residential real property its own separate class and authorized a subclass for owner-occupied primary residences — but the Legislature did not lower the 9.5% rate itself.
The biggest recent change for homeowners is the 25% homeowner exemption (Senate File 69, 2025), which exempts 25% of the first $1,000,000 of fair market value on a single-family residence and its improved land. It first applied for tax year 2025 and has no sunset; beginning with tax year 2026 it requires at least eight months of occupancy in the year, with an exception for active-duty military. Owners aged 65 or older who have paid Wyoming residential property tax for 25 or more years can instead claim the Long-Term Homeowner Exemption — 50% of fair market value — which began in tax year 2025 and is set to sunset July 1, 2027; it cannot be combined with the 25% exemption.
Wyoming also runs an income-based Property Tax Refund Program under Wyo. Stat. §39-3-109 for households whose income is below 145% of the county or state median, whichever is greater; the refund is capped at half the median residential tax or 75% of the bill. Veterans can claim an exemption of $6,000 of assessed value under §39-13-105, raised from $3,000 starting in tax year 2025. These programs are enacted, not proposed.
Why your actual bill differs
The numbers above describe a typical homeowner in this ZIP — not your specific bill. A few things move bills away from the median:
- Overlapping mill levies. Your bill stacks county, school-district, and special-district levies, so two similar homes in different districts can owe different amounts even at the same 9.5% assessment ratio.
- Annual revaluation. Because every county assessor revalues property at fair market value each January 1, a rising local market lifts assessed values year to year — so a recent revaluation can push a bill above the ZIP median.
- Exemptions and refunds. The 25% homeowner exemption, the long-term-homeowner exemption for owners 65+, the veterans exemption, and the income-based refund program each pull a qualifying owner's bill below the median.
Wyoming has no single statewide bill lookup — each county treasurer handles billing. Laramie County's iTax portal is a working example; for other counties, search your county treasurer's site.
Methodology
Data on this page comes from the US Census American Community Survey 5-year estimates, 2020–2024 vintage (released January 29, 2026), at the ZIP Code Tabulation Area (ZCTA) level. After filtering ZCTAs the Census suppresses for privacy or small-sample reasons, this page covers 115 Wyoming ZIPs.
Topcoding in Wyoming. The Census caps median property tax at $10,000, reporting anything higher as $10,001. In Wyoming this affects a handful of high-value resort ZIPs — notably around Teton County and Jackson — where the true median is at least $10,000 and the rate is a conservative estimate. Outside those areas the figures here are true medians.

Frequently asked questions
Why is the median tax in my ZIP different from what I pay?
Median is the middle of the distribution, not your bill. Wyoming taxes residential property on just 9.5% of fair market value, but your bill stacks several overlapping county, school, and special-district mill levies. The 25% homeowner exemption, the long-term-homeowner and veterans exemptions, and the income-based refund move qualifying owners further from the median.
Why might my ZIP show $10,001 as the median tax?
That's the Census topcode for privacy. In Wyoming it shows up in a handful of high-value resort ZIPs, notably around Teton County and Jackson; for those the true median is at least $10,000 and the rate is a conservative estimate, while the rest are true medians.
Where do I find my actual Wyoming property tax bill?
Through your county treasurer. Wyoming has no statewide portal; each of the 23 counties bills and collects its own. Laramie County's iTax portal is a working example.
When does Wyoming data update on this page?
Annually, when the Census Bureau releases a new ACS 5-year vintage. The 2020–2024 vintage released January 29, 2026. The next vintage (2021–2025) typically follows the next year, though the Census has not yet posted its release date.
Why don't you cover other states yet?
State-by-state rollout. Each state needs its own context section (assessment method, exemptions, local taxing structure) to be genuinely useful. High-search-volume states are going live first.
