How Property Tax Works

Crook County property taxes serve as a vital funding source for essential local services including schools, county operations, roads, fire protection, and other municipal services. The county operates under Wyoming's property tax system with an average mill levy of 65.1 for 2025, which translates to approximately $65.10 per $1,000 of assessed value. Property taxes in Crook County are calculated based on the assessed value of real property, which is determined at fair market value as of the assessment date.

Your actual property tax rate will vary depending on your specific location within Crook County due to special taxing districts such as school districts, fire districts, water districts, and other local improvement districts. Each property may be subject to different combinations of these special assessments, making individual tax bills unique to the property's location and applicable service areas.

When Are Property Taxes Due?

For the 2025/2026 tax year in Crook 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 Crook County are additional property tax bills issued when there are changes to property ownership, new construction, or improvements that increase the assessed value during the tax year. These situations trigger a recalculation of taxes based on the new assessed value, prorated for the remaining portion of the tax year.

For example, if you complete a home addition worth $50,000 in March and your tax rate is 65.1 mills, you would receive a supplemental tax bill for approximately $326 ($50,000 × 0.651 = $3,255 annually ÷ 12 months × 9 remaining months). Supplemental taxes are billed separately from your regular property tax bill and have their own due dates, typically 30 days from the bill date.

Escrow & Property Taxes

Most mortgage lenders in Crook County require property tax escrow accounts to ensure timely payment of property taxes. Your lender collects monthly escrow payments along with your mortgage payment, then pays your property taxes directly to the county when due. The escrow amount is calculated by taking your annual property tax bill and dividing by 12 months, often with a small cushion added for potential increases.

Property tax bills in Crook County are typically issued in October for the current tax year. Your lender should receive the bill directly and make payment by the November 15 deadline to qualify for the 3% early payment discount. If you pay your own taxes, you can pay in full by November 15 for the discount, or split payments with half due November 15 and half due May 15. Verify with your lender that taxes are being paid correctly and on time.
