Exemptions & appeals
View exemption application (opens in a new tab)Exemption filing
March 1, 2026 for the 2026 Wyoming 25% homeowner property-tax exemption owner-occupancy application; the 2026 long-term homeowner exemption used the fourth Monday in May (May 25, 2026) under the then-current filing schedule.
Senior relief
Wyoming long-term homeowner relief: an owner or spouse age 65 or older who has paid Wyoming residential property taxes for at least 25 years, owns and occupies the primary residence at least 8 months per year, and applies annually may qualify for the long-term homeowner exemption. Other 2026 relief includes the 25% homeowner exemption for an owner-occupied single-family residence, the veteran exemption, the income/asset-tested property-tax refund, and a county-option low-income senior/disabled deferral program; eligibility and administration are handled by the applicable county assessor or treasurer.
Valuation limits
Wyoming's 4% residential property valuation-increase cap applies statewide rather than as a county-specific rule. It limits qualifying annual increases in residential taxable value, does not cap fair-market-value appraisal, and statutory exclusions apply to items such as new construction and qualifying improvements; the 25% homeowner and long-term homeowner provisions reduce taxable value but are exemptions, not appraisal caps.
For a valuation appeal, use the appeal date in the tax and filing section above. Keep your notice, supporting evidence, and proof of submission.
