That's the good news. The bad news is that it taxes most forms of retirement income. 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 There is no general state sales tax, but you will pay 7% in taxes on accommodations and campgrounds and pay a 4% tax on rental vehicles. Montana allows tourism-dependent local communities such as Big Sky and West Yellowstone to impose a local option sales tax. State law limits the rate to no more than 3%, but the rate and taxable items are both set by local ordinance. Income Tax Range Low: 1% (on up to $2,800 of taxable income)High: 6.9% (on taxable income over $17,000) 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 2014, the maximum exemption was $3,980 if federal adjusted income was $35,190 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.
