Rate Breakdown

Property taxes in Crook County are calculated by multiplying the assessed value (minus exemptions) by the total local millage rate.

How Property Tax Works in Crook County

Property taxes in Crook County are based on the assessed value of your property and the mill levy (tax rate) set by local taxing authorities. Here’s how the process works:

• Assessment: The Crook County Assessor’s Office determines the market value of your property annually. Wyoming law requires assessments to reflect 100% of fair market value.
• Taxable Value: The assessed value is multiplied by the assessment ratio (9.5% for residential, 11.5% for commercial) to calculate taxable value.
• Mill Levy: The taxable value is then multiplied by the mill levy (1 mill = $1 per $1,000 of taxable value). Rates vary depending on school districts, municipalities, and other local entities.

Tax bills are typically mailed in the fall, with payments due the following year.

Available Exemptions

Wyoming offers several property tax exemptions to qualifying residents. Below are key programs available in Crook County:

• Homestead Exemption: Provides a reduction in taxable value for primary residences. Applicants must occupy the home as their primary dwelling.
• Senior Citizen Exemption: Available to homeowners aged 65+ with limited income. This exemption may reduce the property’s assessed value by up to 50%.
• Veteran Exemption: Disabled veterans may qualify for a partial exemption based on their disability rating. Surviving spouses of veterans may also be eligible.
• Disability Exemption: Individuals with permanent disabilities may apply for relief, subject to income limits.

Applications for exemptions must be filed with the Crook County Assessor’s Office by the annual deadline, typically April 1.

Payment Schedule & Deadlines

Crook County property taxes are due annually, with specific deadlines and payment options:

• Payment Deadline: Taxes are due in full by November 10. If this date falls on a weekend or holiday, the deadline extends to the next business day.
• Installment Plan: Taxpayers may pay in two installments: 50% by November 10 and the remaining 50% by May 10 of the following year.
• Late Payments: Delinquent taxes incur interest at 1.5% per month (18% annually). Persistent delinquency may result in a tax lien or foreclosure.

Payments can be made online, by mail, or in person at the Crook County Treasurer’s Office.

Appealing Your Assessment

• Step 1: Contact the Crook County Assessor’s Office to discuss your valuation. Many disputes are resolved informally.
• Step 2: File a formal appeal with the County Board of Equalization by the deadline (typically 30 days after assessment notices are mailed).
• Step 3: Present evidence (e.g., recent appraisals, comparable sales) to support your claim during a hearing.
