Minnesota
For 2026, Minnesotans with AGIs of up to $86,410 for an individual, and up to $110,780 for a couple filing jointly, do not have to pay state taxes on their Social Security income. Residents with higher incomes — up to $126,410 for a single filer and $150,780 for couples — may qualify for a partial tax break on their benefits. Above those thresholds, all federally taxable benefits are subject to state income tax.
Residents may use an alternative method to determine taxes they owe on Social Security income, based on how the deduction worked for all beneficiaries before 2023, when lawmakers changed the state’s policy. However, doing so is unlikely to benefit taxpayers because the income thresholds for the alternative method are not indexed for inflation, according to the Minnesota House Research Department.
Minnesota taxes income at rates ranging from 5.35 percent to 9.85 percent. For more information, contact the Minnesota Department of Revenue.
Montana
Like the federal government, Montana does not tax Social Security for people with overall incomes of less than $25,000 for a single filer and $32,000 for a couple filing jointly. Residents who make more are liable for tax on their benefits, but the state uses a different method than the feds to determine the taxable amount. The state tax form includes a worksheet for calculating the difference.
Montana’s income-tax rates range from 4.7 percent to 5.9 percent. For more information, contact the Montana Department of Revenue.
New Mexico
Social Security income is fully deductible for New Mexicans with AGIs below $100,000 for individuals and $150,000 for couples filing jointly. Above those limits, you must include the portion of your benefits that is subject to federal income tax in your state taxable income.
New Mexico taxes income at rates from 1.5 percent to 5.9 percent. For more information, contact the New Mexico Taxation & Revenue Department.
Rhode Island
The state does not tax benefits for people who have reached full retirement age as defined by the Social Security Administration (66 and 10 months for people born in 1959, 67 for those born in 1960 and later) and have AGIs below certain levels, which are adjusted annually for inflation. As of April 27, the state had not set the thresholds for the 2026 tax year; for 2025, the thresholds were $133,750 for a couple filing jointly or $107,000 for a single filer or head of household.
If you have not reached full retirement age, or you have and your income exceeds the thresholds, your federally taxable benefits are also taxable at the state rates, which range from 3.75 percent to 5.99 percent. For more information, contact the Rhode Island Department of Revenue’s Division of Taxation.
