How Property Tax Works

Washakie County's property tax system is the primary funding source for essential local services including schools, county operations, fire protection, and various special districts. Property taxes in Washakie County are calculated using Wyoming's assessment ratio system, where residential properties are assessed at approximately 9.5% of fair market value, with commercial properties assessed at 11.5%. The county's effective tax rate typically ranges from 0.65% to 0.85% of market value, though this varies significantly based on your specific location within the county.

Your actual property tax rate depends on which special taxing districts serve your property, including school districts, fire districts, library districts, and other local improvement districts. This means two properties with identical market values in different parts of Washakie County may have substantially different tax bills. The county assessor determines property values, while various taxing entities set their individual levy rates that combine to create your total tax rate.

When Are Property Taxes Due?

For the 2025/2026 tax year in Washakie 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 Washakie County are additional property tax bills issued when there are mid-year changes to property ownership, value, or use. The most common triggers include new construction completion, property sales that trigger reassessment, and changes in property classification (such as agricultural to residential use). These supplemental bills represent the difference between taxes already paid and what should have been paid based on the updated assessment.

Supplemental taxes are calculated by determining the new assessed value, applying the current tax rate, and prorating the amount based on the number of months remaining in the tax year. For example, if you complete a $100,000 home addition in March, and your combined tax rate is $65 per $1,000 of assessed value, you would owe approximately $62 in supplemental taxes ($100,000 × 9.5% assessment ratio × $65 rate ÷ $1,000 × 10 months remaining ÷ 12 months).

Section 5

Escrow & Property Taxes

Most mortgage lenders in Washakie County require borrowers to maintain an escrow account for property taxes when the loan-to-value ratio exceeds 80%. Your lender estimates annual property tax costs and collects 1/12 of that amount with each monthly mortgage payment. The lender pays your property tax bills directly to the county when they become due, typically in two installments during the fiscal year.

Property tax bills are generally mailed to your lender if an escrow account exists. It's important to verify that your lender receives the bills and makes timely payments, as you remain ultimately responsible for the taxes even when using escrow. Review your annual escrow analysis statement carefully, as property tax increases or decreases may require adjustments to your monthly escrow payment. If your property taxes increase significantly due to reassessment or new special district levies, you may face an escrow shortage requiring either a lump sum payment or increased monthly payments.
