The tax calculator is based on ESTIMATES of how the passage of the bond could impact individual property taxes. There are other factors that may influence the actual impact: 
  1. This is a re-assessment/reappraisal year for Gallatin County, so individual market values/taxable values may change. Assessments are completed by the Department of Revenue. The market value of all residential, commercial, and industrial real property is determined every two years. January 1, 2020 is the valuation date for the 2021-2022 appraisal cycle. Please see the Montana Reappraisal Plan.
  2. The District's overall taxable value will likely change, impacting the total number of mills the District would need to assess to make the annual payment for the bond. The District will receive the new taxable value for the District the first Monday in August. This is determined and issued by the Department of Revenue.
  3. The interest rates of the bond sales.The District will not have a firm interest rate until the bonds are issued (sold). The Bond Counsel at DA Davidson has provided the District with conservative estimates and have indicated that interest rates are currently low and favorable for the District.
This tax calculator is not intended to provide the actual dollar amounts for increases, but is a tool and starting point to estimate the financial impact based on information available at this time.  
If you have questions about how the re-assessment could impact your property please contact the Department of Revenue at (406) 582-3400.
