Retirement planning used to center on savings rate and investment returns. These days, a growing number of soon-to-retire Americans are asking a different question: which state will actually let them keep more of what they’ve saved. So I put that exact question to ChatGPT, then checked its reasoning against current tax data from the Tax Foundation, SmartAsset, and state revenue departments.
What came back wasn’t a simple “move to Florida” answer. Some of the states on this list are obvious. Others surprised me, especially a couple of income-tax states that quietly protect retirement income better than places with flashier reputations. Here’s how the ranking shook out, and why each state earned its spot.
1. Wyoming
Wyoming sits at the top for a reason that’s almost boring in its simplicity: it just doesn’t ask retirees for much. Wyoming, South Dakota, and Florida lead when retirement tax friendliness is scored across all dimensions, including income tax, Social Security taxation, pension taxation, sales tax, and property tax. There’s no state income tax at all, which means pensions, 401(k) withdrawals, and Social Security checks arrive untouched.
Property taxes stay modest by national standards, and Wyoming has no estate or inheritance tax to worry about later. U.S. News ranks Wyoming among the states with the lowest overall tax burden in the country. For retirees who want predictability more than sunshine, it’s hard to beat.
2. South Dakota
South Dakota rarely gets the glamour of Florida or the mountain views of Wyoming, but its tax structure is just as retirement-friendly. South Dakota ranks alongside Wyoming and Florida when scored across income tax, Social Security taxation, pension taxation, sales tax, and property tax. No state income tax means no state-level bite out of IRA distributions or pension checks.
The state also skips estate and inheritance taxes, which matters more than people expect once they start thinking about what gets passed on. It appears near the top of U.S. News’ list for lowest overall tax burden nationwide. It’s a quiet, practical choice that keeps showing up near the top of every serious ranking.
3. Florida
Florida’s reputation as a retiree magnet isn’t just about weather. Florida is one of the ten most tax-friendly states for retirement according to broad state comparisons. With no state income tax, Social Security, pensions, and retirement account withdrawals all pass through untaxed at the state level.
Property taxes vary by county, and insurance costs have climbed in recent years, so the picture isn’t entirely without tradeoffs. Still, Florida remains one of the states with no individual income tax at all as of 2026. That fundamental advantage keeps it near the front of nearly every retirement tax ranking, ChatGPT’s included.
4. Nevada
Nevada offers the same core benefit as Florida and Wyoming: zero state income tax. States like Florida and Nevada have no state income tax whatsoever. That structural fact means FERS pensions, TSP withdrawals, and Social Security benefits are shielded from any state-level taxation for Nevada retirees too.
Sales tax rates run a bit higher than the national average, which partially offsets the income tax savings for big spenders. Even so, Nevada sits among the eight states with no individual income tax as of 2026. For retirees drawing heavily on 401(k) or pension income, that’s a meaningful head start.
5. Alaska
Alaska rarely comes up in casual retirement conversations, but the tax math holds up. The lack of state income tax in Alaska places the state on the list of tax-friendly retirement destinations, despite otherwise high costs. Every dollar of Social Security, pension, or withdrawal income stays free of state tax.
Property taxes run higher than in many no-tax states. The median property tax bill in Alaska runs around $4,004, similar to nearby Washington. That’s a real cost to weigh, but the absence of any income tax still makes Alaska a legitimate contender for retirees comfortable with a colder, more remote lifestyle.
6. New Hampshire
New Hampshire has quietly become one of the cleanest tax stories in the country. New Hampshire repealed its Interest and Dividends Tax effective January 1, 2025, making it fully income-tax-free. That closes the last gap in what was already a favorable setup for retirees.
There’s no sales tax either, which helps stretch a fixed income further on everyday purchases. New Hampshire stands out for having no income tax alongside a strong rate of primary care need met, an underrated factor for aging residents. It’s a small state that punches well above its weight in retirement tax planning.
7. Tennessee
Tennessee combines no state income tax with a cost of living that still feels reasonable compared to many coastal retirement hubs. Everyday expenses such as utilities and groceries are budget-friendly, and housing is affordable, with options ranging from suburban homes to retirement communities priced below the national average. That combination of tax policy and everyday affordability matters just as much as the sticker price on a state’s tax code.
Beyond the numbers, retirees get real lifestyle variety. Retirees will find plenty to love about Tennessee, from the rich cultural scene, especially in cities like Memphis and Nashville, to the many outdoor activities in the mountains and along the Mississippi River. It’s one of those states where the tax advantage and the quality of life reinforce each other rather than competing.
8. Texas
Texas belongs on this list for the same structural reason as Florida and Nevada. Texas is among the states with no individual income tax as of 2026. Pensions, 401(k) withdrawals, and Social Security income all avoid state taxation entirely.
The tradeoff shows up in property taxes, which run higher than the national average in many Texas counties, funding schools and local services in the absence of income tax revenue. Retirees who plan to downsize or rent rather than hold onto a large home often come out ahead here. For those with substantial retirement account balances, the income tax savings alone can outweigh a higher property tax bill.
9. Delaware
Delaware doesn’t get talked about enough, and that might be its biggest advantage. Delaware may be small in size, but it offers big advantages for retirees, thanks to favorable tax policies, a serene environment, and proximity to major metropolitan areas. It’s an easy state to overlook precisely because it doesn’t market itself the way Florida or Arizona do.
The specifics back up the reputation. Delaware has no state or local sales tax, and residents over 60 can exclude up to $12,500 of investment and qualified pension income, including out-of-state government pensions, from state taxes. For retirees who split time near the Mid-Atlantic corridor, that combination is hard to replicate elsewhere.
10. Mississippi
Mississippi surprises people because it does have a state income tax, yet it exempts nearly all retirement income from it. Mississippi exempts retirement income, though early withdrawals may not qualify for the exemption. That means pensions, Social Security, and most qualified retirement withdrawals pass through tax-free even though the state technically taxes wages.
The remaining income tax rate is also shrinking fast. The Mississippi tax rate is set to be reduced gradually to 3% by 2030, with the rate falling to 4% in 2026, and further decreases planned until the tax is eliminated entirely. Combined with a low cost of living, Mississippi is turning into one of the more underrated retirement tax destinations in the South.
11. Pennsylvania
Pennsylvania is another state that taxes income generally but carves out a clear exception for retirees. Pennsylvania is among a handful of states that charge income taxes to residents but exempt retirement income from that tax. Pensions, 401(k) distributions, and Social Security benefits are generally excluded from the state’s flat income tax.
That exemption matters more in Pennsylvania than in many states because the flat tax rate applies to nearly everyone else. Retirees relying primarily on retirement accounts and Social Security effectively sidestep the tax altogether. Combined with reasonable property taxes in many counties outside Philadelphia, it’s a practical option for retirees who want to stay in the Northeast without a Northeast-sized tax bill.
12. Illinois
Illinois rounds out the list as the most surprising entry, and the one most likely to raise eyebrows. Illinois has a flat income tax of 4.95%, but retirement income is exempt from that tax. That exemption covers pensions, Social Security, and most qualified retirement account withdrawals, which puts Illinois retirees in a similar position to those in true no-tax states, at least on the income side.
The catch is property tax. Illinois features a high property tax rate that partially offsets its retirement income exemptions. Retirees who own a home outright, or who rent instead of buy, tend to benefit the most from Illinois’s approach, while those with expensive real estate may find the savings eaten up elsewhere.
The pattern across all twelve states is consistent even when the paths differ. Some states skip income tax altogether. Others tax income broadly but carve out retirement income specifically, which can end up mattering more than the headline tax rate suggests. What ChatGPT’s ranking got right is something the Tax Foundation and SmartAsset data both confirm: the real cost of retiring somewhere depends on the full picture, income tax, property tax, sales tax, and how a state treats Social Security, not any single number in isolation. For retirees weighing a move, that combination is worth running through a calculator before packing a single box.
