Rate Breakdown

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

How Property Tax Works in Cascade County

Property taxes in Cascade County are based on the "ad valorem" system, meaning taxes are levied according to the assessed value of the property. The process begins with the County Assessor, who determines the fair market value of all real estate. This value is then multiplied by an assessment ratio (typically 100% for most properties in Montana) to determine the taxable value.

The actual tax amount is calculated using millage rates. A "mill" represents one-tenth of one percent (0.001) of the property's taxable value. These rates are determined annually by local taxing jurisdictions, including the county, city, school districts, and special districts. To calculate your estimated tax, multiply the taxable value by the total millage rate and divide by 1,000.

Available Exemptions

Montana offers several tax relief programs to reduce the financial burden on eligible homeowners. These exemptions typically lower the taxable value of the property:

• Homeowner’s Property Tax Credit: Provides relief for primary residences based on income levels.
• Disabled Veteran Exemption: Significant tax relief or full exemptions may be available for veterans with a 100% service-connected disability.
• Senior Citizen Credits: Low-income seniors may qualify for specific credits to help maintain homeownership.
• Agricultural Deferral: Land used primarily for agricultural purposes may be taxed at a lower rate based on its productivity rather than market value.

Payment Schedule & Deadlines

In Cascade County, property taxes are typically billed annually, though some jurisdictions may offer installment plans. It is critical to monitor the deadlines provided on your official tax statement to avoid penalties.

• Due Date: Taxes are generally due by a specific date in the fall (often October), though specific dates can vary by taxing district.
• Late Penalties: Payments made after the deadline are subject to interest charges and penalties, which accrue monthly until the balance is paid in full.
• Tax Sales: Properties with long-term delinquent taxes may be subject to a public tax sale to recover owed funds.

Appealing Your Assessment

If you believe your property has been overvalued, you have the right to appeal the assessment. The process generally begins with an informal review with the Cascade County Assessor's office to discuss discrepancies in property data.

If a resolution is not reached, you may file a formal appeal with the Montana Department of Revenue. This process requires submitting a written request within a specific timeframe following the notice of value. You will be expected to provide evidence, such as recent appraisals or sales data of comparable properties in your neighborhood, to support your claim for a lower valuation.
