Rate Breakdown

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

How Property Tax Works in Teton County

Property taxes in Teton County, Wyoming, are calculated based on the assessed value of your property and the applicable millage (tax) rates. Here’s how the process works:

• Assessment: The Teton 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 determine the taxable value.
• Mill Levy: Tax rates (mill levies) are set by local taxing entities (e.g., schools, county, municipalities). One mill equals $1 per $1,000 of taxable value.

For example, a home with a $1,000,000 market value would have a taxable value of $95,000 (9.5%). At a mill rate of 10 mills, the annual tax would be $950.

Available Exemptions

Wyoming and Teton County offer several property tax exemptions to qualifying owners:

• Homestead Exemption: Reduces taxable value by $3,000 for primary residences (statewide).
• Senior Citizen Exemption: Available to homeowners aged 65+ with income below specified limits. Exempts up to half of the property’s assessed value.
• Veteran Exemption: Disabled veterans may qualify for partial or full exemptions based on disability rating.
• Disability Exemption: Individuals with permanent disabilities may apply for reductions similar to senior exemptions.

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

Payment Schedule & Deadlines

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

• Billing: Tax bills are mailed in October and due by November 10.
• Installments: Taxes may be paid in two installments (November 10 and May 10) if the total exceeds $100.
• Late Payments: Delinquent taxes accrue interest at 1.5% per month (18% annually) and may result in a tax lien or foreclosure.

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

Appealing Your Assessment

If you believe your property’s assessed value is incorrect, you can appeal the assessment:

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

If unsatisfied with the Board’s decision, you may appeal to the State Board of Equalization within 30 days.
