Bigger earned income credit in Montana
Beginning January 1, 2026, the Montana earned income tax credit equals 20% of your federal credit. The credit is refundable, so you can get money back even if you owe no state tax. You must be a Montana resident who qualifies for the federal Earned Income Tax Credit. The credit is reduced when earned income is treated as a dividend from an agricultural organization under federal law.
Lower Montana tax rates from 2027
Starting January 1, 2027, Montana sets lower rates and higher brackets. Married filing jointly pay 4.7% on the first $130,000 and 5.4% above; heads of household pay 4.7% on the first $97,500 and 5.4% above; single or married filing separately, estates, and trusts pay 4.7% on the first $65,000 and 5.4% above. Long-term capital gains use the same thresholds at 3.0% in the lower bracket and 4.1% above. Beginning with tax year 2028, the Department updates bracket amounts each year using a modified inflation factor and publishes them by November 1.
One-year lower 2026 Montana tax rates
For tax year 2026, Montana lowers income tax rates and raises brackets. Married filing jointly pay 4.7% on the first $95,000 and 5.65% above; heads of household pay 4.7% on the first $71,250 and 5.65% above; single or married filing separately, estates, and trusts pay 4.7% on the first $47,500 and 5.65% above. Long-term capital gains use the same thresholds and are taxed at 3.0% in the lower bracket and 4.1% above. These 2026 rules end December 31, 2026.
