Wyoming Property Tax Explained: What Homeowners Need to Know in 2026
Wyoming’s property tax system is one of the most favorable for homeowners in the United States, with an effective rate of about 0.61% — roughly half the national average of 1.1%. This low rate exists because Wyoming funds government services primarily through mineral royalties (oil, gas, coal, and trona taxes) rather than relying heavily on property taxes. The state’s vast energy and mineral wealth generates billions in revenue that subsidizes services other states fund through property and income taxes. But Wyoming’s assessment system has a unique structure that confuses newcomers: residential property is assessed at 9.5% of fair market value, and the mill levy is applied to that assessed value — not to the full market value. Understanding this two-step calculation is essential for anyone who owns or is considering buying a home in Wyoming. This guide explains how Wyoming property taxes work in 2026, what you actually pay, and how the system compares to other states.
How Wyoming Property Taxes Are Calculated
Wyoming’s property tax calculation has three components that multiply together to produce your tax bill.
| Step | What Happens | Example ($300,000 Home) |
|---|---|---|
| 1. Fair Market Value | County assessor estimates market value | $300,000 |
| 2. Assessed Value | Fair market value × 9.5% (state-set ratio for residential) | $28,500 |
| 3. Mill Levy Applied | Assessed value × total mill levy ÷ 1,000 | $28,500 × 64 mills ÷ 1,000 = $1,824 |
The 9.5% assessment ratio is fixed by Wyoming state law for residential property. You cannot change it. Commercial and industrial property is assessed at 11.5% of fair market value. Mineral production and mines are assessed at 100% of gross product value. Agricultural land is assessed at its productive value rather than market value (similar to “current use” programs in other states), which keeps farmland and ranch taxes very low.
The number you can influence is the fair market value in Step 1 (through an appeal if you believe it is too high) and the mill levy in Step 3 (through local elections and budget participation). The 9.5% ratio in Step 2 is non-negotiable.
What the Mill Levy Is and Who Sets It
The mill levy is the tax rate applied to your assessed value. One mill equals $1 per $1,000 of assessed value. Wyoming’s total mill levy for any property is the sum of levies from multiple taxing entities.
| Taxing Entity | Typical Mill Levy Range | Purpose |
|---|---|---|
| County government | 8-15 mills | Roads, law enforcement, courts, county services |
| City/town (if incorporated) | 5-12 mills | Police, fire, streets, parks, city services |
| School district | 25-35 mills | K-12 education (largest single component) |
| Community college | 2-5 mills | Local community college funding |
| Special districts | 1-8 mills | Fire protection, hospital, cemetery, weed/pest |
| State (education) | 12 mills | State foundation for education (fixed statewide) |
| Total Typical Range | 55-75 mills |
The school district levy is the largest component, typically accounting for 40-50% of your total tax bill. Wyoming’s Constitution caps the total mill levy for all local government purposes at 12 mills for counties and 8 mills for cities, with additional limits for school districts and special districts. The state education levy of 12 mills is fixed by the legislature and applies uniformly statewide.
Property Tax Rates by County
| County (City) | Total Mill Levy | Tax on $250K Home | Tax on $400K Home | Tax on $1M Home |
|---|---|---|---|---|
| Laramie (Cheyenne) | 64.3 | $1,527 | $2,443 | $6,109 |
| Natrona (Casper) | 68.5 | $1,627 | $2,603 | $6,508 |
| Albany (Laramie) | 67.0 | $1,591 | $2,546 | $6,365 |
| Campbell (Gillette) | 61.0 | $1,449 | $2,318 | $5,795 |
| Sheridan (Sheridan) | 70.5 | $1,674 | $2,679 | $6,698 |
| Teton (Jackson) | 58.0 | $1,378 | $2,204 | $5,510 |
| Fremont (Lander) | 72.0 | $1,710 | $2,736 | $6,840 |
| Park (Cody) | 66.0 | $1,568 | $2,508 | $6,270 |
| Sweetwater (Rock Springs) | 63.5 | $1,508 | $2,413 | $6,033 |
Teton County (Jackson) has the lowest mill levy despite having the highest property values in the state. The enormous property tax base — driven by multi-million-dollar homes and commercial properties — generates sufficient revenue at a low rate. Campbell County (Gillette) also has a low rate because mineral production taxes supplement property tax revenue significantly. Fremont and Sheridan counties have higher rates because their property tax bases are smaller and mineral revenue supplements are lower.

Why Wyoming Taxes Are So Low
Wyoming’s property taxes are low because the state has alternative revenue sources that most states lack.
| Revenue Source | Annual Revenue (approx.) | Impact on Property Taxes |
|---|---|---|
| Mineral severance taxes | $700M–$1.2B | Funds state services that other states fund via income/property tax |
| Federal mineral royalties | $500M–$800M | 48% of federal mineral royalties return to Wyoming |
| Mineral production tax (ad valorem) | $400M–$600M | Directly reduces local property tax burden |
| State sales tax | $600M–$800M | 4% state rate funds general services |
| Permanent Wyoming Mineral Trust Fund | $25B+ endowment | Investment earnings supplement general fund |
The Permanent Wyoming Mineral Trust Fund is a sovereign wealth fund that has accumulated $25+ billion from mineral royalties since its creation in 1974. Investment earnings from this fund flow into the state’s general fund, reducing the need for taxes on residents. This is similar to Alaska’s Permanent Fund — Wyoming’s mineral wealth, accumulated over decades, subsidizes the cost of living for every resident.
The risk: if mineral production declines significantly (coal consumption has dropped 50% since 2008, and Wyoming produces 40% of U.S. coal), the revenue base that keeps property taxes low could erode. The state has used the Trust Fund’s earnings as a buffer, but a sustained decline in mineral revenue could eventually pressure property taxes upward. For homebuyers, this means Wyoming’s low-tax environment is a current advantage that may moderate over the next 10-20 years as the energy transition continues.
How Wyoming Compares to Other States
| State | Effective Property Tax Rate | Tax on $300K Home | State Income Tax | Total Tax Burden Rank |
|---|---|---|---|---|
| Wyoming | 0.61% | $1,830 | 0% | #1 lowest total |
| Colorado | 0.51% | $1,530 | 4.4% | Moderate |
| Montana | 0.74% | $2,220 | 4.7%–6.75% | Moderate-high |
| Idaho | 0.63% | $1,890 | 5.8% | Moderate |
| Nebraska | 1.61% | $4,830 | 2.46%–6.64% | High |
| South Dakota | 1.22% | $3,660 | 0% | Low (no income tax) |
| New Jersey | 2.23% | $6,690 | 1.4%–10.75% | Highest in nation |
Wyoming ranks #1 in overall tax burden (lowest) when combining property taxes, income taxes, and sales taxes. Colorado has a slightly lower property tax rate (0.51% vs. 0.61%), but the 4.4% income tax more than negates this advantage. South Dakota also has no income tax but charges nearly double Wyoming’s property tax rate (1.22% vs. 0.61%). Wyoming’s combination of zero income tax AND low property taxes is unique among U.S. states. Our affordability calculator shows how this low-tax environment expands your purchasing power.
Assessment and Appeals
Wyoming county assessors are required to value all property at fair market value, with full reappraisals every 6 years and annual market-based adjustments between reappraisals. If you believe your assessment is too high, you can appeal through a structured process:
- Informal review: Contact your county assessor’s office first. Many disputes are resolved informally by correcting factual errors (wrong square footage, incorrect bedroom count) or presenting comparable sales data.
- County Board of Equalization: File a written petition within 30 days of receiving your assessment notice (typically mailed in March-April). The county commissioners hear appeals during their May-June equalization session.
- State Board of Equalization: If the county board rules against you, appeal to the state level within 30 days ($25 filing fee).
- District Court: Final appeal option for complex cases.
At Wyoming’s low effective rate, the annual savings from a successful appeal are modest in dollar terms — a $30,000 reduction in fair market value saves approximately $175-$200 per year depending on your county’s mill levy. But over a 10-year ownership period, even modest savings compound to $1,750-$2,000. For high-value properties (Jackson, Sheridan luxury), the savings scale proportionally and can be $1,000-$5,000 per year.

Special Programs and Exemptions
| Program | Eligibility | Benefit |
|---|---|---|
| Property Tax Refund Program | Age 65+ or disabled; household income under $33,300 | Refund of portion of property taxes paid |
| Veterans Exemption | Veterans with service-connected disability | Exemption on portion of assessed value |
| Agricultural Land Assessment | Land used for agricultural production | Assessed at productive value, not market value |
| Mineral Assessed Valuation | Mineral production on property | Mineral value assessed separately at 100% |
The Property Tax Refund Program is the most broadly applicable. Qualifying seniors and disabled residents with household income under $33,300 can receive a refund of a portion of their property taxes. The refund is calculated on a sliding scale based on income — lower income households receive larger refunds. Applications are filed annually with the Wyoming Department of Revenue. Contact the department or your county treasurer for current application forms and deadlines.

Frequently Asked Questions
How much are property taxes in Wyoming?
The statewide average effective rate is approximately 0.61% of fair market value. On a $300,000 home, expect roughly $1,700-$2,050 per year depending on your county’s mill levy. On a $500,000 home, $2,800-$3,450 per year. On Jackson’s median of $2.2 million, approximately $12,100 per year. These are among the lowest property taxes in the nation — a $300,000 home in New Jersey would pay $6,690 per year for the same value. Our property tax calculator gives exact estimates for any value and county.
Why is Wyoming’s assessment at 9.5% instead of 100%?
Wyoming’s Constitution allows the legislature to set different assessment ratios for different property classes. Use our rent affordability calculator for detailed numbers. The 9.5% ratio for residential property was established to keep residential taxes low relative to commercial (11.5%) and mineral (100%) property. The ratio does not make your taxes lower in itself — the mill levy is adjusted to generate the needed revenue regardless of the ratio. But the different ratios shift more of the tax burden onto commercial and mineral properties, which effectively subsidizes residential owners. This is a policy choice that benefits homeowners.
Will Wyoming property taxes increase if mineral revenue declines?
Possibly, over the long term. Wyoming has avoided property tax increases for decades because mineral severance taxes, federal mineral royalties, and the Permanent Mineral Trust Fund have funded services without relying heavily on property taxes. If coal and oil production decline significantly, the state may eventually need to increase property taxes to maintain service levels. The $25+ billion Trust Fund provides a substantial buffer, but it is not infinite. For homebuyers, this is a 10-20 year risk, not an immediate concern — Wyoming’s tax structure is secure for at least the medium term.
How does Wyoming property tax compare to neighboring states?
Wyoming has the lowest combined tax burden (property + income + sales) of any state that borders it. Colorado’s property taxes are slightly lower (0.51%) but its 4.4% income tax makes the total burden higher. Montana charges 0.74% property tax plus up to 6.75% income tax. Idaho charges 0.63% property tax plus 5.8% income tax. Nebraska and South Dakota both charge significantly higher property tax rates. Wyoming’s zero income tax combined with low property taxes creates the most favorable tax environment in the Mountain West and Great Plains.
When are Wyoming property taxes due?
Wyoming property taxes are due in two installments: the first half is due by November 10, and the second half is due by May 10 of the following year. Late payments incur a penalty of 3% in the first month and 18% per year interest thereafter. If your mortgage includes an escrow account, the lender collects taxes monthly as part of your mortgage payment and pays the county directly. If you pay taxes yourself (no escrow), set calendar reminders for both due dates — the penalties for late payment are steep. Our mortgage calculator includes property taxes in the monthly payment estimate.
