How Property Tax Works

Duchesne County, Utah operates on an ad valorem property tax system that funds essential local services including education, public safety, infrastructure, and county operations. Property taxes are assessed annually as of January 1st and are based on the fair market value of real property within the county. The Duchesne County Clerk/Auditor's Office works in conjunction with the Utah State Tax Commission to establish tax rates and collect revenue for various local government entities.

The effective property tax rate varies significantly by location within Duchesne County due to the overlay of multiple special taxing districts, including school districts, fire districts, water districts, and other municipal service areas. While the county's base certified tax rate is 0.1731% (0.001731), property owners typically pay a combined rate ranging from approximately 0.8% to 1.2% when all applicable district taxes are included. This variation means two similar properties in different areas of the county may have substantially different tax bills based on the services and districts that serve their specific location.

Section 4

Supplemental Tax Bills

Supplemental taxes in Duchesne County are triggered when there are changes in property ownership or improvements made to existing properties after the January 1st assessment date. Common triggers include the sale or transfer of property, completion of new construction, additions to existing structures, or other improvements that increase the property's assessed value mid-tax year.

When supplemental taxes are levied, they are calculated on a pro-rated basis from the date of the change through June 30th of the tax year. For example, if a new home is completed and occupied on April 1st, the supplemental tax would cover the three-month period from April through June. The calculation uses the same tax rate applicable to your property's location, applied to the increase in assessed value. Property owners receive a separate supplemental tax bill that must be paid in addition to their regular annual property tax bill, with payment typically due within 30 days of the bill date.

Escrow & Property Taxes

Most mortgage lenders in Duchesne County require borrowers to maintain an escrow account for property tax payments, particularly for loans with less than 20% down payment. Lenders collect monthly escrow payments as part of your mortgage payment, typically 1/12th of your annual property tax bill plus a small cushion for rate increases. The lender holds these funds in a separate account and pays your property taxes directly to Duchesne County when they become due on November 30th each year.

Property owners with escrow accounts should receive an annual escrow analysis from their lender, usually in late fall, showing the account balance and any adjustments needed for the coming year. If property taxes increase due to higher assessments or rate changes, your monthly escrow payment may increase accordingly. You can verify that your lender has made the payment by checking with the Duchesne County Treasurer's Office or accessing online payment records. If you pay off your mortgage or refinance, remember that the responsibility for paying property taxes transfers back to you directly.

Frequently Asked Questions

Q: When are property taxes due in Duchesne County for the current fiscal year? A: Property taxes for FY 2025-2026 are due November 30, 2025. If not paid by this date, a secondary deadline of February 1st, 2026 applies with additional penalties and interest.

Q: What tax credits are available and do I need to apply? A: Utah offers several tax credits including veteran disability credits (up to $521,620 of taxable value based on disability percentage), homestead credits for primary residences, and senior/disabled person credits. All credits require separate applications and are not automatically applied. Contact your county assessor for specific eligibility requirements and application deadlines.

Q: How does the homestead credit work? A: The homestead credit limits annual assessment increases on your primary residence, not the total market value. You must own and reside in the property for at least 10 months of the year and file an application. This credit caps assessment growth rather than reducing your home's assessed value.

Q: When are properties reassessed and can I appeal my assessment? A: Properties are assessed annually as of January 1st. Assessment notices are typically mailed in the spring. You have the right to appeal your assessment through a formal process with deadlines usually in late spring or early summer. Contact the Duchesne County Assessor's Office for specific appeal procedures and deadlines.

Q: What are the penalties for late payment? A: Properties not paid by November 30th incur penalties and interest. If unpaid by the February 1st secondary deadline, additional penalties apply and properties may be subject to tax sale proceedings.

Q: Can I pay my property taxes online? A: Contact the Duchesne County Treasurer's Office directly for available online payment options and accepted payment methods for property taxes.

Q: Why do property tax rates vary within Duchesne County? A: Different areas of the county are served by different combinations of special taxing districts (school districts, fire districts, water districts, etc.). Each district levies its own tax rate, so your total rate depends on which districts serve your specific property location.

Q: How are special district taxes determined? A: Special districts such as fire protection, water, sewer, and lighting districts each set their own tax rates based on their service needs and budgets. These rates are added to the base county rate to determine your total property tax rate.
