How Property Tax Works

Iron County, Utah operates on a property tax system that serves as the primary funding mechanism for essential local services including schools, county government operations, fire protection, and various special districts. Property taxes in Iron County are collected annually with a current tax rate of approximately 0.002010 (or $2.01 per $1,000 of assessed value) for the 2025 tax year, though this rate varies significantly depending on your specific location within the county due to different combinations of special taxing districts.

The actual property tax rate you pay depends on which special taxing districts serve your property, such as school districts, fire districts, cemetery districts, and municipal services. This means two properties of equal value in different areas of Iron County may have different tax bills. Property is assessed at 100% of fair market value in Utah, and while the state has no assessment cap, various tax credits are available to qualifying property owners who submit the required applications.

When Are Property Taxes Due?

For the 2025/2026 tax year in Iron County, property taxes are due in two installments:

Pro tip: If you pay through mortgage escrow, your lender splits these payments across your monthly mortgage. If you pay directly, set calendar reminders to avoid late penalties.
Section 4

Supplemental Tax Bills

Supplemental taxes in Iron County are triggered by changes in property ownership, new construction, or improvements that increase a property's assessed value during the tax year. When these events occur, the county calculates the difference between the old and new assessed values and applies the current tax rate to determine additional taxes owed.

For example, if you purchase a home in Iron County that was previously assessed at $250,000 but sells for $400,000, the assessor will likely increase the assessed value to reflect the sale price. You would then owe supplemental taxes on the $150,000 increase in assessed value, prorated for the portion of the tax year you own the property. These supplemental bills are typically issued within 60-90 days of the triggering event.

Escrow & Property Taxes

Most mortgage lenders in Iron County require property tax escrow accounts to ensure timely payment of property taxes. Your lender collects 1/12th of your estimated annual property tax bill each month along with your mortgage payment. The lender holds these funds in an escrow account and pays your property taxes directly to Iron County when they become due on December 1st.

Lenders typically conduct an annual escrow analysis to ensure adequate funds are collected, which may result in escrow payment adjustments. You'll receive an annual escrow statement showing all deposits and payments. If you pay your own property taxes, you must ensure payment reaches the Iron County Treasurer's office by 5:00 PM on December 1st or is postmarked by that date to avoid penalties.

Frequently Asked Questions

Q: When are Iron County property taxes due? A: Property taxes for FY 2025-2026 are due by December 1, 2025, by 5:00 PM or postmarked by that date. A 1% penalty (minimum $10 per parcel) applies for late payment, with additional interest accruing thereafter.

Q: What tax credits are available and do I need to apply? A: Iron County offers various tax credits including low-income abatements for qualifying seniors and disabled residents. ALL credits require annual applications and are NOT automatic. Applications for most credits are due by March 1st each year.

Q: How does the homestead credit work? A: Utah's homestead credit helps limit assessment increases on your primary residence rather than reducing market value. This credit requires annual application and filing to maintain eligibility. Contact the Iron County Assessor for current application procedures.

Q: How often is my property reassessed? A: Iron County reassesses properties annually, with assessments typically mailed in the summer. The assessment reflects the property's value as of January 1st of the tax year.

Q: How do I appeal my property assessment? A: Assessment appeals must be filed with the Iron County Board of Equalization within 45 days of receiving your assessment notice. Contact the Assessor's office at (435) 477-8338 for appeal procedures.

Q: Can I pay my property taxes online? A: Yes, Iron County typically offers online payment options through their official website. Contact the Treasurer's office for current online payment procedures and any associated fees.

Q: Why do special district taxes vary across the county? A: Different areas of Iron County are served by different combinations of special districts (fire, water, sewer, etc.). Your total tax rate depends on which districts serve your specific property location.

Q: What happens if I don't pay my property taxes? A: Unpaid property taxes become a lien against your property. After the penalty and interest period, the county may eventually initiate tax sale proceedings to collect delinquent taxes.
