Rate Breakdown

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

How Property Tax Works in Natrona County

Property taxes in Natrona 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 Natrona 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: Taxes are calculated by applying the mill levy (1 mill = $1 per $1,000 of taxable value) to your property’s taxable value. Rates vary by district (e.g., school, city, county).

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

Available Exemptions

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

• Homestead Exemption: Reduces taxable value by up to $3,000 for primary residences. Applicants must occupy the home as of January 1.
• 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: Veterans with service-related disabilities may qualify for partial or full exemptions based on disability rating.
• Disability Exemption: Individuals with total and permanent disabilities may be eligible for exemptions similar to seniors.

Applications for exemptions must be filed with the Natrona County Assessor by April 1.

Appealing Your Assessment

If you believe your property’s assessed value is incorrect, follow these steps to appeal:

• Informal Review: Contact the Natrona County Assessor’s Office before May 1 to discuss discrepancies.
• Formal Appeal: File a written appeal with the County Board of Equalization by June 1. Include supporting evidence (e.g., recent appraisals, comparable sales).
• State Appeal: If unsatisfied, you may appeal to the Wyoming State Board of Equalization within 30 days of the county’s decision.

Appeals are more likely to succeed with documented proof of overvaluation. Deadlines are strict, so act promptly.
