How Property Tax Works

Sheridan County, Wyoming operates on a property tax system that funds essential local services including schools, law enforcement, road maintenance, and county government operations. The county uses a tax rate of 0.20% applied to assessed values, with residential and commercial properties assessed at 9.5% of their market value. Property taxes constitute a significant portion of local government revenue, with projections showing increases of 5.5% to 18% in recent years.

Your actual tax rate may vary depending on your specific location within Sheridan County due to special taxing districts such as school districts, fire districts, and municipal improvements. These additional assessments are layered on top of the base county rate. The county assessment system is administered by the Sheridan County Assessor's Office, which determines property values and processes exemption applications.

Section 4

Supplemental Tax Bills

Supplemental taxes in Sheridan County are triggered by changes in property ownership, new construction, or significant property improvements that occur after the annual assessment date. When these events happen, the county assessor calculates the difference between the old and new assessed values and applies the current tax rate to determine supplemental taxes owed.

For example, if you complete a home addition worth $50,000 in market value after the assessment date, the county would assess this at $4,750 (9.5% assessment ratio) and apply your local tax rate to determine the supplemental tax. These taxes are prorated based on the number of months remaining in the tax year and are billed separately from your regular property tax bill.

Escrow & Property Taxes

Most mortgage lenders in Sheridan County require property tax escrow accounts for borrowers with less than 20% down payment. Your lender collects monthly payments equal to 1/12 of your annual property tax bill plus a small cushion as allowed by federal law. The lender pays your property taxes directly to the county when due.

Property taxes are due in two installments: 50% by September 1st (payable by November 10th) and 50% by March 1st of the following year. If you pay the full amount by December 31st, no interest is charged. Your lender will typically pay the September installment from your escrow account and the March installment from continued monthly collections. You should verify with your lender that payments are made timely and review your annual escrow analysis for accuracy.
