Tips for Great Falls Homeowners
- •Appeal your assessment: If your home is assessed higher than its market value, you can file a property tax appeal. Studies suggest 30–60% of properties are over-assessed. Most counties offer a free informal review process.
- •Check your exemptions: Homestead exemptions can reduce your taxable value and are available to primary residents in most states. Senior, veteran, and disability exemptions may also apply. Exemptions must typically be applied for — they are not automatic.
- •Know your assessment cycle: Montana reassesses properties periodically. After buying a home, your next tax bill may reflect a new assessment based on your purchase price. Budget accordingly, especially if you bought above prior assessed values.
- •Compare ZIP codes before buying: Even within Great Falls, effective tax rates can vary significantly across ZIP codes due to different school district overlays. Use PropertyTaxByZip to compare specific ZIPs before choosing a neighborhood.
