Two retirees with identical Social Security checks can end up with different amounts of spendable income for one reason that has nothing to do with their work history: the state they live in. Most states leave Social Security benefits untouched, but a small group still taxes some of that income, quietly trimming the monthly check. For anyone weighing a move in retirement, the difference can add up to real money over the years.
The Federal Tax Comes First
Before any state gets involved, the federal government already taxes Social Security for many recipients. Depending on total income, up to 85 percent of benefits can be counted as taxable at the federal level, which catches far more retirees than the state rules do. The Social Security Administration’s own benefits planner explains how combined income determines whether a portion of the check is federally taxable.
State taxation is a separate and much narrower question. A large majority of states either have no income tax at all or specifically exempt Social Security, so most retirees never owe a state a dime on their benefits. The issue only arises in the shrinking number of states that still reach for a share.

Which States Still Reach for a Share
The list of states that tax Social Security has been getting shorter for years as legislatures phase the tax out. As of the current tax year, about eight states still tax some benefits: Colorado, Connecticut, Minnesota, Montana, New Mexico, Rhode Island, Utah and Vermont. West Virginia recently finished phasing its tax out, and Kansas, Missouri and Nebraska dropped theirs in recent years, a trend that keeps the roster in motion from one year to the next.
Being on the list does not automatically mean a tax bill. Most of these states shield lower- and middle-income retirees through income-based exemptions, age deductions or credits, so many residents owe little or nothing even where the tax technically exists. The bite tends to fall on retirees with higher total income from pensions, withdrawals or investments stacked on top of their benefits.
How the Exemptions Actually Work
The mechanics vary from state to state, which is why two neighbors in the same state can be treated differently. Minnesota, for example, offers a Social Security subtraction that fully or partly removes benefits from state taxable income once a filer’s income falls below a set threshold, as its Department of Revenue lays out in its benefit subtraction rules. Colorado takes a different path, allowing older residents to deduct qualifying retirement and Social Security income under its pension and annuity subtraction. Because those thresholds and deductions are adjusted over time, the only reliable figure is the one on a state’s current-year instructions, not a number remembered from an earlier filing season.
Checking a Household’s Own Exposure
Because the rules turn on total income and vary by state, the only way to know whether benefits will actually be taxed is to run the numbers against a specific state’s current forms. A retiree in a state that taxes benefits can often shrink or erase the bill by managing when income is realized, for instance by spreading out retirement-account withdrawals or timing a large capital gain so that total income stays under an exemption threshold in a given year. Two households with the same benefits can land on opposite sides of that line depending on how the rest of their income is arranged.
The stakes also shift over time as legislatures act. Several states have phased out their Social Security tax entirely in recent years, and others have raised their exemption thresholds, so a tax that applied a while ago may no longer bite. A retiree working from an old memory that benefits were taxable, or safe, can be relying on a rule that has since changed, which is why the current-year instructions from a state’s revenue department are the figure that actually counts.
What the Location Choice Is Worth
The gap matters most for retirees who are already deciding where to spend their later years. A move across a state line can change whether benefits are taxed at all, and for a household drawing heavily on pensions or retirement accounts, that can be worth hundreds of dollars a year. State income tax on benefits is also only one piece of the puzzle, sitting alongside property taxes, sales taxes and how a state treats pension and withdrawal income, so a state that spares Social Security can still be costlier overall.
The practical takeaway is to treat the benefit-tax question as one factor among several and to confirm it against a state’s revenue department rather than a general reputation. The Social Security Administration notes that whether benefits are taxed, and how much, depends on total income and the rules where a person files — which is why the same check can stretch further in one state than in another.
