March 1, 2026 for the 2026 Wyoming 25% homeowner exemption owner-occupancy application.
Senior relief
2026 Wyoming long-term homeowner exemption: an owner or spouse age 65 or older who has paid Wyoming residential property taxes for at least 25 years, occupies the primary residence at least 8 months per year, and applies annually may receive a 50% exemption; the 2026 deadline was May 26, 2026 because the fourth Monday in May was Memorial Day. Veteran exemptions and the Wyoming property-tax refund program may also apply.
Valuation limits
Qualifying single-family homes and associated land receive an automatic 4% cap on annual property-tax increases; new owners, recent construction, major remodels, and additions do not qualify until the applicable following year. The cap does not cap fair-market value.
For a valuation appeal, use the appeal date in the tax and filing section above. Keep your notice, supporting evidence, and proof of submission.
