Rate Breakdown

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

How Property Tax Works in Park County

Property taxes in Park 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 Park County Assessor’s Office determines the market value of your property annually. Wyoming law requires assessments to reflect 100% of market value.
• Taxable Value: The assessed value is multiplied by the assessment rate (9.5% for residential, 11.5% for commercial) to calculate the taxable value.
• Mill Levy: The taxable value is then multiplied by the mill levy (rate per $1,000 of value). Mill rates vary depending on your location and local districts (e.g., schools, counties, municipalities).

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

Available Exemptions

Wyoming and Park County offer several property tax exemptions to qualifying residents:

• Homestead Exemption: Available to homeowners who occupy their primary residence. This exemption reduces the taxable value by up to $3,000 or 50% of the assessed value (whichever is less).
• Senior Citizen Exemption: Residents aged 65+ with limited income may qualify for a reduction in taxable value. Income thresholds apply.
• Veteran Exemption: Disabled veterans or surviving spouses may qualify for partial or full exemptions based on disability rating.
• Disability Exemption: Individuals with permanent disabilities may be eligible for tax relief, subject to income limits.

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

Payment Schedule & Deadlines

Park County property taxes are due annually, with the following key dates:

• Billing: Tax bills are mailed in November and are due in two installments.
• First Installment: Due by December 31. Late payments incur a 2% penalty.
• Second Installment: Due by May 10 of the following year. Late payments incur a 2% penalty plus interest.
• Delinquency: Unpaid taxes after May 10 may result in a lien or tax sale.

Payments can be made online, by mail, or in person at the Park 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 Park 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 at a hearing.
• Step 4: If unsatisfied, you may appeal to the State Board of Equalization within 30 days of the county’s decision.

Deadlines are strict, so act promptly if you disagree with your assessment.
