Wyoming has among the lowest effective property tax rates in the nation, in large part because residential property is assessed at just 9.5% of fair market value. A 2025 law also added a 25% homeowner exemption on owner-occupied primary residences.
Wyoming assesses residential property at 9.5% of fair market value (industrial at 11.5%, mineral production at 100%), a major reason its effective rates are among the lowest. County assessors determine fair market value (physical inspection at least every six years, valued as of January 1), and rates are set in mills from local budget requests, with state caps on mill levies.
| Home Value | Estimated Annual Tax | Monthly (Escrow) |
|---|---|---|
| $250,000 | $1,425 | $119/mo |
| $286,000 (median) | $1,630 | $136/mo |
| $600,000 | $3,420 | $285/mo |
Effective rates vary within Wyoming. These figures are median-tax-to-median-value estimates from U.S. Census ACS data (2019–2023 ACS 5-year (SmartAsset)) for some of the most populous counties:
| County | Effective Rate |
|---|---|
| Laramie County | 0.58% |
| Natrona County | 0.57% |
Among these counties, effective rates range from about 0.57% in Natrona County to 0.58% in Laramie County. Your actual rate depends on the local mill/millage set by your county, city, and school district.
A 2025 law (Senate File 69) provides a 25% homeowner exemption on the fair market value of an owner-occupied single-family primary residence and its land, applied to the first $1,000,000 of value. For tax year 2026 it requires an application filed October 1, 2025–March 1, 2026, and the owner must occupy the home at least eight months of the year. A household may use either this exemption or the long-term homeowner exemption, not both.
The Long-Term Homeowner Exemption gives a 50% assessed-value exemption on the primary residence (and up to 35 acres) to owners 65+ who have paid Wyoming residential property taxes for 25+ years and occupy the home at least eight months a year, due by the fourth Monday in May. The Veterans Exemption reduces assessed value by $6,000 for qualifying resident veterans, and a Property Tax Refund Program runs in years the legislature funds it.
Bills are generally issued by September 1. Taxpayers may pay in full by December 31, or in two installments with the first half due November 10 and the second half the following May 10. Late payments accrue interest.
A homeowner who disputes the assessor's fair market value must contest it within 30 days of the assessment notice mailing. The appeal goes to the county assessor and, if unresolved, to the county board of equalization, with further appeal to the State Board of Equalization and district court.
Wyoming's average effective property tax rate is about 0.57% of home value, among the lowest in the nation. A key reason is that residential property is assessed at only 9.5% of its fair market value before mill levies apply.
Under a 2025 law (SF 69), owner-occupied primary residences receive a 25% exemption on the first $1 million of fair market value. For 2026 it must be claimed by application filed between October 1, 2025 and March 1, 2026, and the owner must live in the home at least eight months of the year.
Yes. Long-term homeowners 65+ who have paid Wyoming property taxes for 25+ years can get a 50% exemption on their primary residence, and qualifying resident veterans receive a $6,000 assessed-value exemption. A state Property Tax Refund Program is also available in years the legislature funds it.
