January 1: Property Value Date

Your property’s market value is determined as of January 1 of the tax year. County assessors estimate what your property would likely have sold for on this date, using recent market sales and other valuation data. Later changes to the housing market generally do not affect that year’s assessment.

July: Assessment Notices

Most homeowners receive a Notice of Property Valuation and Tax Changes during July. Utah law requires counties to mail valuation notices no later than July 22.

Your notice typically includes:

  • Your property’s estimated market value
  • Your projected property taxes
  • Information about Truth in Taxation hearings
  • Instructions for filing an appeal

Review this notice carefully as soon as it arrives. This is the starting point for both the appeal process and Truth in Taxation hearings.

Appeal Deadline: September 15

Sep 15

Valuation Appeal Deadline

If you believe your property’s market value is incorrect, you generally must file your appeal by September 15, or within the alternative time allowed after your notice. Always verify the deadline printed on your assessment notice – filing periods can vary in limited circumstances. Waiting until your tax bill arrives is usually too late.

Truth in Taxation Hearings

During the summer, cities, counties, school districts, and other taxing entities may hold public Truth in Taxation hearings before increasing property tax revenue. Your valuation notice generally lists the dates, times, and locations of hearings affecting your property. These hearings give residents an opportunity to comment before tax increases are adopted.

Tax Bills

After local tax rates have been finalized, counties prepare and mail annual property tax bills – typically in October or November. Your bill reflects your property’s assessed market value, applicable exemptions, local tax rates, and any special district assessments.

Payment Deadline: November 30

Nov 30

Property Tax Payment Deadline

Annual property taxes are due on November 30. If November 30 falls on a weekend or legal holiday, the due date moves to the next business day. Unpaid balances may become subject to penalties and interest after this deadline.

Many homeowners pay through an escrow account maintained by their mortgage lender. Even so, it is worth verifying that your payment was made and that your exemptions are correctly reflected on your bill.
