That's the good news. The bad news is that Montana taxes virtually all forms of retirement income, including Social Security. The state allows a pension- and annuity-income exemption of up to $3,980 per person, subject to certain income limitations. Residents 65 and older can exclude up to $800 for single filers (up to $1,600 for married filers) of interest income from state taxes. State Sales Tax No sales tax. Resort areas such as Big Sky, Red Lodge and West Yellowstone have local sales taxes. Income Tax Range Low: 1% (on up to $2,900 of taxable income)High: 6.9% (on taxable income over $17,400). Montana permits filers to deduct some of their federal income tax. Effective income tax rate: 5.4%/individual, 6.5%/joint Social Security Social Security benefits are taxable. The taxable amount may be different from the federally taxable amount because Montana taxes some types of income that the federal government does not, and vice versa. Exemptions for Other Retirement Income The state allows a partial pension exemption adjusted for inflation every year. For 2016, the maximum exemption was $4,070 if federal adjusted income was $33,910 or less. If both spouses are receiving retirement income, each spouse can take up to the maximum exemption if the couple falls under the income threshold. Early distributions from an IRA do not qualify for this exemption. Single residents 65 and older can exclude up to $800 of interest income from state taxes, while married joint filers can exclude up to $1,600.
