Many U.S. states rely heavily on residents’ income to meet their government’s revenue needs.
According to the Tax Foundation, individual income taxes comprised 33 percent of all U.S. state tax collections in the fiscal year 2023. Eight U.S. states collect zero personal income taxes, relying instead on property taxes, business taxes, and other levies to fill their coffers, while Washington state only taxes income from capital gains, the Foundation reported, leaving 41 U.S. states that mandate individual tax collection.
In 2025, 9 states will levy taxes on Social Security income. However, that figure is down from 13 states taxing Social Security in 2020, with Nebraska, Kansas, and Missouri ditching the Social Security tax in the last five years.
Here’s a closer look at the nine remaining U.S. states taxing Social Security, and how they’re going about it in 2025.
Colorado
Not every Colorado resident has to pay the 4.25 percent flat rate on Social Security taxes. Citizens aged 55 to 64 may deduct up to $95,000 (married filing jointly) or $75,000 (single filers) of their Social Security income. Any resident above those income levels gains a $20,000 deduction.Connecticut
In Connecticut, residents are taxed on Social Security, but it’s relatively simple to bypass. Married couples can deduct up to $100,000 of Social Security income, while single residents can deduct $75,000.Minnesota
In Minnesota, any resident earning $82,190 or less is exempt from state Social Security taxes. Married couples earning $105,380 or less can do the same. Residents earning more than that can be taxed on Social Security income, with rates ranging from 5.35 percent to 9.85 percent.Montana
In Montana, lower-income residents have a simple path to avoid paying Social Security taxes. Single filers who earn $25,000 or less annually can avoid the tax, while married couples who earn $32,000 or less can do the same.State taxpayers earning more must pay Social Security taxes based on a state tax range of 4.7 percent to 5.9 percent of their annual income.
