If during the tax year you were a resident or partyear resident of Montana, or if you were a nonresident who received Montana source income and your federal gross income, excluding unemployment compensation, is equal to or greater than the threshold for your filing status as listed in the chart below, you need to file a Montana income tax return.
You are entitled to an additional exemption if you are blind or your spouse is blind. Increase your federal gross income by $2,560 to determine if you are required to file.
