Wyoming taxes homes on 9.5% of their fair market value [1], and over the last few years the Legislature has stacked several breaks on top. The biggest is a 25% homeowner exemption for people who live in their home [2][3]. Longtime owners 65 and older can take 50% instead [2][3], every home gets an automatic 4% cap on yearly increases [2][3], and qualifying veterans get $6,000 of assessed value off [3][4].

The 25% homeowner exemption
Wyoming exempts 25% of the fair market value of a single-family home and the land that goes with it, applied to the first $1 million of value [2]. That covers houses, modular and mobile homes, townhouses and condos that are privately owned single-family dwellings [2]. Starting with tax year 2026, you have to live in the home at least eight months of the year, with an exception for active-duty service members whose service keeps them away from their legal domicile [2].
The Department of Revenue says owners have to notify the assessor that the home is owner-occupied, and that the notification for the 2027 tax year is due by March 1, 2027 [3]. You can file it through the Department of Revenue’s website [3].
Long-term homeowners 65 and older
If you or your spouse is 65 or older and has paid residential property tax in Wyoming for 25 years or more, on any home, you can exempt 50% of the fair market value of your primary residence, on up to $3 million of value [2]. The home has to be where you actually live at least eight months of the year, and the exemption covers the dwelling and up to 35 acres of land you own with it [2]. If you sold one Wyoming home and bought another, the time in both counts [2].
- How to claim: file a sworn claim with your county assessor by March 1 [2]. After that, you stay qualified by contacting the assessor’s office by phone, mail or another method by March 1 each year to confirm you still qualify [2].
- Surviving spouses of someone who qualified keep the exemption [2].
- One or the other: you can’t take this exemption and the 25% homeowner exemption on the same home in the same year [2].
The automatic 4% cap
Every single-family home gets a built-in limit on yearly increases: any assessed value of the house, and of the improved land under it, that’s more than last year’s value plus 4% is exempt [5][3]. There’s no application [3].
The cap doesn’t apply, and the home is valued in full, if the increase comes from new construction or an addition, or if you bought the home during the prior calendar year [5]. Transfers between spouses, by divorce decree, into your own trust or into a company you own don’t count as a purchase [5].
Veterans
Qualifying veterans get an exemption of $6,000 of assessed value a year [4]. Because homes are assessed at 9.5% of value [1], that’s roughly the tax on about $63,000 of a home’s market value. To qualify, you have to have been a Wyoming resident for at least three years and be one of these [4]:
- An honorably discharged veteran of World War I, World War II, Korea or Vietnam during the dates the law lists.
- An honorably discharged veteran awarded the armed forces expeditionary medal or another campaign medal for service in an armed conflict in a foreign country.
- A disabled veteran with a compensable service-connected disability certified by the VA or a branch of the armed forces.
- A surviving spouse, or surviving parents if there’s no spouse; the Department of Revenue notes Gold Star parents became eligible July 1, 2025 [3].
File a sworn claim with your county assessor by the fourth Monday in May [4]. After the first year, you stay qualified by contacting the assessor each year [4][3]. The exemption applies to your principal residence, and the Department of Revenue says it can also be used against vehicle registration fees [4][3].
The income-based refund program
Wyoming’s Property Tax Refund Program pays back part of last year’s tax on your home if your household income is no more than 145% of the median for your county or the state, whichever is higher [6]. You have to have lived in Wyoming at least five years and occupied the home at least nine months of the tax year [6]. The refund is up to 75% of last year’s property tax, but no more than half the median residential property tax in your county [6].
There’s also an asset test unless your property tax is more than 10% of your household income: for 2025, the Department of Revenue lists a limit of $169,866 per adult, not counting your home, one car per adult, household goods and retirement accounts [3][6]. Apply to your county treasurer or the Department of Revenue by the first Monday in June [6].
Teton County residents have one more option: a property tax deferral program for owners over 62 or disabled with limited income, which can put off up to half the tax on a qualifying home [3].
When taxes are due
Half the year’s tax is due from September 1 and payable by November 10, and the other half is due from March 1 and payable by May 10 of the next year [7]. If you pay the whole year by December 31, no interest or penalty is charged [7].

What is the Wyoming homeowner property tax exemption?
An exemption of 25% of the fair market value of a single-family home and its land, applied to the first $1 million of value. Starting with tax year 2026, you have to live in the home at least eight months of the year. For the 2027 tax year, the Department of Revenue says the owner-occupied notification is due by March 1, 2027.
Is there a property tax break for seniors in Wyoming?
Yes. The long-term homeowner exemption takes 50% off the fair market value of a primary residence, on up to $3 million of value, if the owner or spouse is 65 or older and has paid Wyoming residential property tax for at least 25 years. You claim it with the county assessor by March 1. You can't take it and the 25% exemption on the same home in the same year.
Do Wyoming homeowners get a cap on assessment increases?
Yes, automatically. For a single-family home and its land, any increase in assessed value above last year's value plus 4% is exempt. It doesn't apply to new construction or additions, or if you bought the home during the prior calendar year.
What property tax help do Wyoming veterans get?
An exemption of $6,000 of assessed value each year for qualifying honorably discharged veterans, certain disabled veterans and surviving spouses who have lived in Wyoming at least three years. The claim is due to the county assessor by the fourth Monday in May, and it can also be used against vehicle registration fees.
