How Property Tax Works

Property taxes in Uinta County, Wyoming fund essential local services including public schools, county operations, fire protection, and various special districts. The county follows Wyoming's assessment system where all real property is assessed at 9.5% of fair market value, with tax rates applied to this assessed value rather than the full market value.

Your actual property tax rate depends on your specific location within Uinta County, as different areas are served by various special taxing districts such as school districts, fire districts, and improvement districts. These overlapping jurisdictions each levy their own rates, which combine to determine your total property tax obligation. Most tax credits and exemptions require annual application and are not automatically applied to your property.

When Are Property Taxes Due?

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 are additional property tax bills issued when there are mid-year changes to your property's assessed value. Common triggers include change of ownership, completion of new construction, or significant improvements to existing property. When these events occur, the county assessor determines the new assessed value and calculates the difference between the old and new tax obligations.

For example, if you complete a $100,000 home addition in March, the supplemental tax would be calculated on the increased assessed value ($100,000 × 9.5% = $9,500 additional assessed value) multiplied by your area's total tax rate, prorated for the remaining months in the tax year. This supplemental bill is separate from your regular property tax installments.

Escrow & Property Taxes

Most mortgage lenders require property tax escrow accounts, where you pay 1/12 of your annual property tax with each monthly mortgage payment. Your lender collects these funds and pays your property taxes directly to Uinta County on your behalf. Lenders typically pay the first installment by the November 10 deadline and the second installment by the May 10 deadline.

Your lender will analyze your escrow account annually and may adjust your monthly payment if tax amounts change. You'll receive an escrow analysis statement showing any shortage or surplus. If your taxes increase due to reassessment or rate changes, your monthly escrow payment will increase accordingly. Always verify that your lender has made the payments on time, as you remain ultimately responsible for ensuring taxes are paid by the due dates.

Q: How do special districts affect my tax bill? A: Your property may be located within multiple special districts (fire, water, school, etc.), each with their own mill levy.
