Wyoming's 2025 Long-Term Homeowner Exemption (HB003): 50% Off for Age 65+ With 25 Years of Wyoming Residential Property Tax Paid, Plus the Property Tax Refund Program for Anyone With 5 Years of Residency

Updated April 2026

Wyoming's senior property tax framework changed substantially in the 2025 legislative session. The new Long-Term Homeowners Exemption (HB003) creates a 50% property tax exemption on the primary residence for homeowners age 65 or older who have paid residential property tax in Wyoming for 25 years or more — a meaningful new benefit for long-tenure WY seniors. Layered alongside the older Property Tax Refund Program, which is broader (5 years of WY residency, lower asset threshold, available to homeowners regardless of age), Wyoming now offers more substantive senior tax relief than it did pre-2025. Both programs operate alongside Wyoming's already-low property tax burden — WY assesses residential at 9.5% of fair market value (one of the lowest residential assessment rates in the country) and has no state property tax above the local levies.

Long-Term Homeowners Exemption (HB003, 2025): The New Senior Headline

Eligibility:

Owner or spouse age 65 or older.
Paid residential property tax in Wyoming for 25 years or more. The 25-year requirement does not have to be on the same property — it tracks total years of WY residential property tax payment.
Owner must reside in the primary residence for at least 8 months of the year.
Property is the owner's primary residence.

Mechanic: provides a 50% exemption of the residential real property used as primary residence. So a senior with a $300,000 home (assessed at $28,500 with WY's 9.5% residential ratio) gets 50% of the assessed value exempted, meaning property tax is computed on $14,250 of assessed value rather than $28,500. At WY's typical millage rates, this often translates to substantial dollar savings for long-tenure WY seniors. Application is filed in person at the County Assessor's Office; deadline is the fourth Monday in May.

Property Tax Refund Program: Broader Eligibility, Asset-Tested

Distinct from the Long-Term Homeowner Exemption, the Property Tax Refund Program is a refund mechanism with broader age eligibility but tighter asset/income tests:

Wyoming resident for at least 5 years.
Occupied the property 9 or more months during the prior tax year.
Total assets less than $163,019 per adult household member (excluding the home itself, one vehicle per adult, and retirement accounts).
Asset requirement is waived if property tax paid exceeds 10% of total household gross income — protecting cash-poor, asset-rich seniors who would otherwise be excluded by the asset test.

Program operates as a refund check from the Wyoming Department of Revenue after the property tax has been paid in full. The 10%-of-income asset waiver is unusual and worth understanding: a low-income senior whose home produces a high property tax bill relative to income gets the refund regardless of asset balance — recognition that asset accumulation doesn't imply current cash-flow capacity.

Is your Wyoming residential assessed value defensible?

Both the Long-Term Homeowner Exemption (50% off) and the Refund Program are computed against your actual property tax bill. If your assessment is too high, the relief shields a smaller proportional share. An assessment review at your county pushes the base down.

Wyoming's Underlying Low-Tax Structure

Even before either senior program, Wyoming's baseline property tax burden is among the lowest in the country. Several structural reasons compound:

9.5% residential assessment ratio — among the lowest residential ratios nationally.
No state property tax above local levies; the state doesn't levy a real property tax of its own.
Mineral severance taxes fund a substantial portion of state government, reducing pressure on local property taxes for general revenue.

For long-tenure WY seniors, the combined effect of the 9.5% ratio + low millage + 50% Long-Term Homeowner Exemption can produce property tax burden well under $1,000/year on homes that would generate $4,000+ in tax in higher-cost-of-living states.

Frequently Asked Questions

I moved to Wyoming 12 years ago at age 60. Do I qualify for the Long-Term Homeowner Exemption?

Not yet. The Long-Term Homeowners Exemption requires both age 65+ AND 25 years of paid Wyoming residential property tax. At 12 years of WY residency you're short by 13 years on the residency requirement, regardless of your current age. The 25-year requirement is statutory and cannot be waived. You may qualify for the broader Property Tax Refund Program once you reach 5 years of WY residency (you would have already met that threshold if you moved 12 years ago) — that program has asset/income tests but no minimum-residency-tenure requirement beyond the 5-year baseline. Run the Refund Program calculation; it may produce meaningful relief while you're working toward the 25-year mark.

My total assets are $200,000 in Wyoming, but my property tax is $1,800 on income of $15,000. Do I qualify for the Refund Program?

Yes — the asset test is waived because your property tax exceeds 10% of household gross income. $1,800 on $15,000 income is 12% — above the 10% threshold. The waiver clause specifically protects asset-rich, cash-poor seniors whose nominal asset base would otherwise exclude them from a program designed for cash-flow relief. File the Property Tax Refund Program application with WY DOR; document the property tax / income ratio. The refund is computed against actual property tax paid, with caps under the program rules. The waiver is one of the more taxpayer-friendly provisions in the WY relief framework.

Can I claim both the Wyoming Long-Term Homeowner Exemption AND the Property Tax Refund Program?

The two programs operate at different levels and may both apply to the same senior. The Long-Term Homeowner Exemption is a 50%-off reduction on assessed value before tax computation; the Refund Program is a post-payment refund based on property tax actually paid. For an eligible senior with 25+ years of WY residency, age 65+, owning a primary residence, and meeting the Refund Program's asset/income tests, both can apply: the exemption shrinks the bill, then the Refund Program partially refunds what was paid. Run both program rules carefully — the WY DOR can confirm what the combined relief looks like for your specific situation.
