When are property taxes due in Iron County?

The county has not yet posted its 2026 date; last year's taxes were due Monday, December 1, 2025, because November 30 fell on a Sunday. Last year the county required mailed payments to be postmarked by the due date, in-person payments by 5:00 p.m., and online payments before 11:59 p.m. Mountain time. Taxes not paid or postmarked by the due date are charged a penalty of 1% or $10 per parcel, whichever is greater. If the taxes and penalty are not paid in full by January 31, 2027, the penalty becomes 2.5% or $10, whichever is greater, and interest is charged back to January 1, 2027 at a yearly rate set by state law of no less than 7% and no more than 10%.
