How Property Tax Works

Sublette County, Wyoming operates under a property tax system that funds essential local services including schools, county government operations, fire protection, and various special districts. Property taxes in Sublette County are based on assessed value, which is determined by applying Wyoming's assessment ratios to the market value of real property as established by the county assessor.

The effective property tax rate in Sublette County is approximately 0.5% for the 2025 levy year, though actual rates vary significantly by location within the county due to special taxing districts such as school districts, fire districts, and other local improvement districts. Property owners should expect their specific tax rate to differ based on which special districts serve their property location. The county uses these tax revenues to maintain roads, fund emergency services, support the school system, and provide other essential municipal services to residents.

Supplemental Tax Bills

Sublette County issues supplemental tax bills when there are mid-year changes to property ownership or improvements that affect assessed value. The most common triggers include property sales that result in reassessment, completion of new construction, or additions to existing structures that weren't included in the annual assessment.

Supplemental taxes are calculated by applying the current tax rate to the difference between the new assessed value and the previous assessed value, prorated for the portion of the tax year remaining. For example, if a property's assessed value increases by $50,000 due to completed renovations in January, and the tax rate is 0.5%, the supplemental tax would be approximately $250 ($50,000 × 0.005) for that tax year. These supplemental bills are typically issued within 30-60 days of the triggering event and have separate due dates from regular property tax bills.

Section 5

Escrow & Property Taxes

Most mortgage lenders in Sublette County require property tax escrow accounts for borrowers with less than 20% down payment, though some lenders may require escrow regardless of down payment amount. Your lender collects monthly escrow payments equal to 1/12 of your estimated annual property tax bill, plus insurance premiums, and pays these bills on your behalf when due.

Property taxes in Sublette County are due December 1st each year, and lenders typically pay these bills in late November or early December. Your lender will provide an annual escrow statement showing all deposits and payments made from your account. If your property taxes increase due to reassessment or rate changes, your lender will adjust your monthly escrow payment accordingly, though they may require you to make up any shortage over 12 months or in a lump sum, depending on federal escrow regulations and your loan terms.
