Wyoming Property Tax Law Changes 2026: What Homeowners Need to Know

Updated March 2026

Wyoming Property Tax Snapshot: 2026

• Median home value: $228,900
• Average annual tax: $1,396
• Effective tax rate: 0.61%
• Assessment ratio: 9.5% of market value
• Reassessment cycle: annual

9.5% Residential Assessment Ratio

Wyoming assesses residential property at just 9.5% of fair market value (industrial at 11.5%). A $250,000 home has an assessed value of only $23,750. This low ratio keeps property taxes very manageable. The Department of Revenue sets assessment standards and equalizes across counties.

Mineral Revenue Subsidy

Wyoming's extensive mineral production (coal, oil, natural gas) generates significant tax revenue that subsidizes local government. This mineral wealth is the primary reason Wyoming can maintain low property tax rates without an income tax. However, as energy markets fluctuate, so does the subsidy -- which could put upward pressure on property taxes in low-production years.

Veteran Exemption

Wyoming provides a $3,000 property tax exemption for qualifying veterans. This is applied to assessed value. For a state with a 9.5% ratio, $3,000 of assessed value equals approximately $31,500 of market value exempted. Disabled veterans may qualify for additional benefits.

No Income Tax

Wyoming has no state income tax, making it one of the most tax-friendly states overall. The combination of no income tax, low property taxes (subsidized by minerals), and no corporate income tax makes Wyoming attractive for retirees and businesses alike.

Appeal Deadline

File appeals by June 1 or 30 days from your assessment notice (whichever is later) with the county Board of Equalization. The State Board of Equalization hears appeals from county decisions.
