Wyoming property taxes by county
Across Wyoming, the median owner-occupied home pays $1,767 a year in real-estate taxes on a median home value of $309,700 — an effective property-tax rate of 0.571%. That ranks Wyoming #38 of 51 states and the District of Columbia (1 = highest). This page carries all 23 Wyoming county-equivalents in the Census data — 23 with a published effective rate — sortable by rate, taxes paid, home value, income, or five-year change. It also sets out how property tax actually works in Wyoming: how property is assessed, which exemptions exist and who qualifies, the deadline and body for an appeal, and the payment schedule and penalties — each hand-sourced from official Wyoming sources. Figures are U.S. Census Bureau ACS 2020-2024 5-year estimates.

How property tax varies across Wyoming
Across Wyoming's 23 county-equivalents with a published rate, the effective property-tax rate runs from 0.681% in Weston County down to 0.443% in Sublette County — a 1.5× spread inside a single state, which is why a statewide average tells a buyer very little.
The largest median real-estate tax bill in Wyoming is $7,267 in Teton County, which ranks #22 of 23 by RATE — while the state's highest rate, 0.681%, is in Weston County, where the median bill is $1,510. Dollars and rate are different questions and rank counties differently.
Measured against the national median effective rate of 0.937%, 0 of Wyoming's 23 ranked counties sit above it and 23 below. Wyoming as a whole ranks #38 of 51 (1 = highest).
Median home value statewide is $309,700, but within Wyoming it ranges from $1,633,900 in Teton County to $206,000 in Washakie County — the denominator of the effective rate, and the main reason two counties with similar bills can show very different rates.
Statewide, the median real-estate tax bill equals about 2.3% of median household income. That share is heaviest in Teton County (5.8%) and lightest in Niobrara County (1.7%).
Comparing the non-overlapping Census periods 2015–2019 and 2020–2024, median real-estate taxes rose by a statistically significant amount in 22 of Wyoming's 23 counties with a comparable trend, fell significantly in 0, and showed no statistically significant change in 1.

How property tax works in Wyoming
Assessment, exemptions, appeals and payment are set by Wyoming law and practice, so they apply to every county in the table above. Each fact is taken from an official government source and linked to it.
- How property is assessed
- Local County Assessor's offices assess property, with the Property Tax Division maintaining a uniform CAMA system in all 23 counties. Wyoming statute requires assessors to annually update property values and to complete a detailed review of real property characteristics at least once every six years. Market value reflects worth as of January 1; residential property is assessed at 9.5% of market value. source →
- Exemptions & credits
- The Veteran's Property Tax Exemption gives $6000 in assessed value to qualifying combat veterans or surviving spouses, applied for by the fourth Monday in May. The Property Tax Refund Program, due the first Monday in June, requires household income below the greater of 145% of the county or state median household income and refunds up to one-half the median residential property tax or 75% of the bill, whichever is less. source →
- Appealing an assessment
- Appeals must be filed with the County Assessor in which the property is located no later than 30 days from the date of the Assessment Notice, must address market value rather than the tax rate, and must include supporting evidence. A County Board of Equalization decision may be appealed to the State Board of Equalization within 30 days of the decision's entry or its mailing postmark, whichever is later. source →
- Payment schedule & penalties
- Taxes are due and payable at the office of the County Treasurer of the county in which the taxes are levied. Fifty percent of the taxes are due by November 10 each year and the remaining fifty percent by May 10 of the succeeding calendar year. If the entire tax is not paid on time, interest may be charged. source →
- Why rates vary within the state
- Tax rates, expressed as mill levies, are set by the various political entities with the legal power to levy taxes: counties, school districts, cities, towns and special taxing districts such as water, sewer and cemetery districts. The tax notice itemizes the amount paid to each taxing entity. Tax due equals taxable value multiplied by the tax rate. source →
- What makes this state's system distinctive
- Wyoming taxes only a small statutory fraction of market value, and the fraction differs by use. Residential and commercial property are assessed at 9.5% of market value while industrial property is assessed at 11.5%. A commercial property with a $100,000 market value therefore carries a taxable value of just $9,500. source →

Frequently asked questions
- What is the average property tax rate in Wyoming?
- Statewide, Wyoming's effective property-tax rate is 0.571% — the state median real-estate taxes ($1,767) divided by the state median home value ($309,700), from the Census ACS 2020-2024 5-year estimates. The national figure is about 0.937%, which puts Wyoming at #38 of 51 (1 = highest). Individual counties vary widely; the table above shows every one.
- Which Wyoming county has the highest property taxes?
- By effective rate, Weston County is highest in Wyoming at 0.681% (median bill $1,510), and Sublette County is lowest at 0.443% (median bill $1,665). Ranked by dollars paid rather than rate the order changes, because home values differ so much across the state — the table above shows both columns and sorts on either.
- What property tax exemptions are available in Wyoming?
- The Veteran's Property Tax Exemption gives $6000 in assessed value to qualifying combat veterans or surviving spouses, applied for by the fourth Monday in May. The Property Tax Refund Program, due the first Monday in June, requires household income below the greater of 145% of the county or state median household income and refunds up to one-half the median residential property tax or 75% of the bill, whichever is less. Eligibility and filing are handled by your county assessor, and the exemption you qualify for changes your bill far more than the county you are in — the rates above are county medians and do not account for any exemption.
- How do I appeal a property tax assessment in Wyoming?
- Appeals must be filed with the County Assessor in which the property is located no later than 30 days from the date of the Assessment Notice, must address market value rather than the tax rate, and must include supporting evidence. A County Board of Equalization decision may be appealed to the State Board of Equalization within 30 days of the decision's entry or its mailing postmark, whichever is later. Missing the deadline usually means waiting a full year, so check the date on your own assessment notice rather than relying on a general figure.
- When are property taxes due in Wyoming?
- Taxes are due and payable at the office of the County Treasurer of the county in which the taxes are levied. Fifty percent of the taxes are due by November 10 each year and the remaining fifty percent by May 10 of the succeeding calendar year. If the entire tax is not paid on time, interest may be charged. If your taxes are paid through a mortgage escrow account, your servicer pays on this schedule on your behalf.
- How is property assessed in Wyoming?
- Local County Assessor's offices assess property, with the Property Tax Division maintaining a uniform CAMA system in all 23 counties. Wyoming statute requires assessors to annually update property values and to complete a detailed review of real property characteristics at least once every six years. Market value reflects worth as of January 1; residential property is assessed at 9.5% of market value. This is why an effective rate computed from market value — as every rate on this page is — will not match the millage rate printed on your bill: the two are applied to different bases.
