Iron County, Utah property-tax payment and appeal deadlines
Tax bills, payment rules, and valuation-review windows are controlled by the local jurisdiction and the governing state framework. The reviewed record below separates published figures from items that still require confirmation with Iron County Assessor.
Rate context
Confirmno single verified 2026 countywide effective rate; Utah rates vary by tax area and taxing entity, and county/state sources do not publish one countywide effective rate.
Statement mailing
PublishedNovember 1, 2026; Iron County's official assessment schedule states tax notices are sent by the Treasurer on November 1.
Payment deadline
PublishedNovember 30, 2026; Iron County's assessment schedule states property taxes are due and payable by November 30 and become delinquent thereafter.
Valuation protest
Published5:00 p.m. MDT on September 15, 2026 or the later last day of the 45-day period beginning when the Auditor mails the valuation notice, whichever is later; Iron County's BOE page publishes this rule.
Do not assume a grace period.
The reviewed record identifies the payment timing above but does not establish a universal penalty schedule for this page. Late charges, interest, collection costs, tax-sale procedures, and lien or foreclosure timelines can depend on state law and the local collector’s process. If the deadline is close or a balance is delinquent, contact the tax collector directly and request the current payoff amount in writing.
Treat a published payment deadline as a hard operational date and retain your receipt or confirmation number.
From assessment to collection
01Valuation and notice
Review the assessment notice as soon as it arrives. The protest window may run from the notice date rather than from the payment due date.
02Statement and account review
Match the tax statement to the parcel or account number and confirm exemptions, assessed value, taxing units, credits, and balance.
03Payment confirmation
Use the official collector channel, then save the receipt, transaction reference, and date posted. A bank submission is not always the same as a county posting date.
