Property-tax appeals in Wyoming
Deadlines, evidence, and a packet you file yourself — for homes, multifamily, and commercial property in Wyoming.
State rules verified from public sources| Deadline rule | File a written statement with the county assessor specifying why the assessment is incorrect not later than 30 days after the date the assessment schedule was properly sent (postmark or electronic transmission date controls) (W.S. 39-13-109(b)(i)). Assessment schedules are mailed on or before the fourth Monday in April (W.S. 39-13-103(b)(vii)). |
|---|---|
| First hearing body | County Board of Equalization (the county commissioners), which must issue written findings by October 1; then the Wyoming State Board of Equalization on notice of appeal within 30 days after the county decision is entered or mailed, whichever is later; then district court. |
| Who may represent you | The contestant may act through an agent — the assessor and the person contesting, or his agent, must disclose witnesses and exchange evidence no later than 30 days before the county board hearing (W.S. 39-13-109(b)(i)). |
Wyoming assesses annually at fair market value as of January 1 — there is no multi-year cycle to ride. Build the evidentiary record at the county hearing: the State Board reviews the county record rather than re-trying the facts, and the pre-hearing exchange deadline is statutory. Hearing dates vary by county (often June); the 30-day objection clock is the hard one.
What wins in Wyoming
Homes are argued on comparable sales and uniformity. Income property is argued on the income approach — rent roll, expenses, and a supported cap rate. The packet builds the argument that matches your property type, with your evidence organised as exhibits.
