For the large majority of retirees, a Social Security check arrives untouched by any state income tax. Only a small group of states still counts benefits as taxable income, and that group has grown smaller nearly every year as legislatures move to exempt Social Security entirely. The distinction can be worth hundreds or thousands of dollars annually, and it explains why the tax treatment of benefits often ranks alongside housing costs and climate when older Americans decide where to spend retirement.
How state taxation of benefits works
Most states with an income tax choose to exclude Social Security from it, and nine states levy no personal income tax at all, which leaves benefits untaxed at the state level by default. The result is that a clear majority of states never touch the payment. The Social Security Administration notes that whether benefits face any tax depends on total income, and states that do tax them generally build in their own exemptions tied to age or earnings.
The short list of states that still tax benefits has been shrinking for several years running. West Virginia completed a multi-year phase-out that removed its tax at the start of 2026, dropping the count to eight, and other states have advanced similar legislation. Where a tax remains, it rarely applies to everyone: most of these states shield lower- and middle-income retirees through income thresholds that rise over time, so the number of people who actually owe is smaller than the list of taxing states suggests.
Because the rules turn on residency, a retiree’s exposure can change simply by relocating. A move across a state line can eliminate a state tax on benefits entirely, though it may trade one cost for another in the form of property or sales taxes.

The federal tax that applies everywhere
Avoiding a state tax does not mean benefits are always tax-free, because a separate federal tax can apply regardless of where a person lives. The Internal Revenue Service uses a measure it calls combined income, which adds half of annual benefits to other income such as pensions, wages, and taxable withdrawals from retirement accounts. The IRS guidance on Social Security income sets the thresholds where the tax begins.
For an individual filer, up to half of benefits become taxable once combined income passes $25,000, and up to 85 percent become taxable above $34,000. For a married couple filing jointly, those thresholds sit at $32,000 and $44,000. The figures have never been indexed to inflation, so each year rising incomes and cost-of-living adjustments pull more retirees above the lines.
A retiree unsure whether the federal tax applies can work through the IRS interactive assistant on taxable benefits, which walks through the combined-income calculation. Even at the highest tier, no more than 85 percent of a benefit is ever subject to tax, meaning at least 15 percent always arrives tax-free at the federal level.
What the pattern means for retirement location
The steady disappearance of state taxes on benefits reflects competition among states to attract and keep retirees, who bring spending and stable income without adding to school or workforce demands. That trend favors older savers, but it also makes a state’s current status worth confirming rather than assuming, since a tax that existed a few years ago may already be gone.
The state question is only one piece of the picture. A state with no tax on benefits may carry high property taxes or expensive home insurance, while a state that taxes benefits lightly might offset it with a lower overall cost of living. The tax on Social Security is easy to isolate and compare, but it should be weighed against the full slate of levies a household would face.
The interaction between the state and federal rules can produce outcomes that surprise retirees who focus on only one. A person in a state with no income tax still owes the federal tax on benefits if combined income clears the thresholds, while a retiree in a taxing state may owe nothing to that state because its exemption is generous enough to cover a modest benefit. The label a state carries matters less than how its specific exemption applies to a given household’s income.
Provisional income is the lever a household can actually control. Because the combined-income formula counts withdrawals from traditional retirement accounts but not distributions from a Roth, converting some savings to a Roth in lower-income years can hold future income below the taxable thresholds. Coordinating the timing of pension income, part-time earnings, and account withdrawals across the calendar is the practical way to limit how much of a benefit any government, state or federal, ultimately taxes.
The federal tax, by contrast, follows a retiree everywhere and is harder to escape, which makes managing combined income the more durable strategy. Timing withdrawals from tax-deferred accounts, using Roth funds that do not count toward the threshold, and spreading income across years can keep a household below the points where more of a benefit becomes taxable, no matter which state it calls home.
