Rate Breakdown

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

How Property Tax Works in Platte County

Property taxes in Platte 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 Platte County Assessor’s Office determines the market value of your property, which is then adjusted to reflect the taxable assessed value (typically 9.5% of market value for residential properties).
• Mill Levy: Taxing entities (e.g., school districts, counties, municipalities) set mill levies, where 1 mill = $1 per $1,000 of assessed value. The total mill rate is the sum of all applicable levies.
• Tax Calculation: Multiply your assessed value by the total mill rate to estimate your annual tax bill. For example, a $200,000 home assessed at $19,000 with a 70-mill levy would owe $1,330 annually.

Available Exemptions

Wyoming offers several property tax exemptions to qualifying residents. Key programs include:

• 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 home’s assessed value by up to 50%.
• 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 apply for relief, subject to income and eligibility criteria.

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

Payment Schedule & Deadlines

Platte County property taxes are due annually, with the following key dates and options:

• Billing: Tax statements are mailed by November 1 each year.
• Deadline: Full payments are due by December 31. Late payments incur penalties (1.5% monthly interest).
• Installments: Partial payments are accepted, but the full balance must be paid by May 10 of the following year to avoid penalties.
• Delinquency: Unpaid taxes after May 10 may result in a tax lien or eventual foreclosure.

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

Appealing Your Assessment

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

• Review Your Assessment: Check your assessment notice (mailed by April 1) for accuracy.
• File an Appeal: Submit a written appeal to the Platte County Board of Equalization by the deadline (typically within 30 days of the assessment notice). Include evidence (e.g., recent appraisals, comparable sales).
• Hearing: The Board will review your case and issue a decision. If unsatisfied, you may appeal to the State Board of Equalization.
