The Property Tax Assistance Program (PTAP) helps citizens on a fixed or limited income by reducing the property tax rate on their home.

The PTAP benefit only applies to the first $200,000 of your primary residence’s market value. Your income and marriage status determine the reduction.

For homes on agricultural or forest land, the benefit applies to the home and one-acre home site.

Eligibility

To qualify you must:

  • Own or currently be under a contract to purchase a home or mobile/manufactured home
  • Live in the home as your primary residence for at least seven months of the year
  • Have a 2016 Federal Adjusted Gross Income (FAGI), excluding capital and income losses, less than:
    Single
    $21,607
    Married or Head of Household
    $28,810
  • Include your spouse’s income in your FAGI regardless of whether they are a co-owner of the home.

If you are a new Montana resident, include a copy of your 2016 federal income tax return with your completed application.

If your only income is from social security, veterans’ benefits and/or other nontaxable sources, include a copy of your social security statement and/or other income documentation with your completed application.

Benefit

Depending on your marital status and income, the reduction is 80%, 50%, or 30% of the normal tax rate. The income ranges are updated each year for inflation.
