Retirees scanning their statements see the numbers clearly enough. A $1 million traditional 401(k) balance represents decades of deferred gratification. Withdraw it in California and the state claims roughly $130,000. Cross into any of 13 other states and that bill reads zero.

Those 13 places have built deliberate exclusions into their tax codes. Nine impose no broad income tax whatsoever. Four others tax wages but spare qualified retirement distributions entirely. And this year Michigan completes a phase-in that brings most retirees under a generous deduction cap, effectively joining the group.

The distinction matters. Federal taxes still apply. Yet state rules can swing annual liability by five figures or more. For households living on fixed incomes, the difference funds travel, healthcare gaps or simply peace of mind.

Michigan’s 2026 completion of its retirement income tax phase-out marks the clearest recent shift in policy.

Start with the cleanest cases. Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington and Wyoming levy no personal income tax. A pension check, IRA distribution or 401(k) withdrawal passes through untaxed at the state level. New Hampshire finished repealing its interest and dividends tax at the start of 2025. Washington imposes a 7% capital-gains tax on long-term gains above an indexed threshold around $270,000 but leaves ordinary retirement income alone.

These nine states recover revenue elsewhere. Texas and Florida rely on property and sales taxes. Property levies in Texas often exceed 1.6% effective. Florida’s insurance market has tightened after repeated storms, driving premiums higher for many coastal homeowners. Yet for retirees whose primary income arrives as distributions rather than wages, the math frequently tilts in their favor.

Illinois, Mississippi and Pennsylvania take a different route. They maintain flat or graduated income taxes but carve pensions, 401(k) withdrawals, IRA distributions and often Social Security out entirely. Illinois applies its 4.95% rate to wages yet exempts qualified retirement income. Pennsylvania follows similar logic and adds a note that early withdrawals before age 59½ can still face tax.

Iowa joined them after lawmakers expanded relief. Residents age 55 or older now shield pension, annuity and IRA income from state tax. The state’s flat rate sits at 3.8% on remaining taxable income.

Michigan’s change proves especially noteworthy. Public Act 4 of 2023 set a multi-year phase-out. By tax year 2026 the deduction reaches roughly $66,000 for singles and $132,000 for joint filers, indexed for inflation. Most retirees drawing typical pension and Social Security amounts now owe nothing on that income at the state level. The provision excludes certain 457 plans but covers standard pensions, 401(k)s and IRAs.

Recent analysis from 24/7 Wall St. published Sept. 19, 2026, framed the stakes plainly. Pull $1 million from a traditional 401(k) in one of these jurisdictions and state tax liability equals zero. The piece highlighted how such policies create quiet advantages that many overlook until filing season arrives.

Data compiled by CountryTaxCalc in its June 2026 update confirms 13 core states deliver full exemption on most retirement income. It lists the nine no-tax states plus Illinois, Iowa (with the age qualifier), Mississippi and Pennsylvania. Michigan’s new deduction effectively adds a 14th for the typical retiree. The guide also notes partial exemptions in another dozen states, though those fall short of outright relief.

Alabama receives honorable mention in several tallies for exempting government and military pensions. Hawaii protects many public pensions. But the clearest, broadest shelter remains concentrated in those 13 to 14 jurisdictions.

Social Security treatment has grown more uniform. Forty-two states and the District of Columbia avoid taxing the benefit. Only eight still impose some form of tax: Colorado, Connecticut, Minnesota, Montana, New Mexico, Rhode Island, Utah and Vermont. West Virginia completed its phase-out effective 2026, according to multiple tax analysts. Income thresholds and credits blunt the bite even in those eight.

Yet income tax represents only one column. Property taxes, sales taxes and estate taxes shape the full picture. SmartAsset’s mid-2026 review, covered by Yahoo Finance on June 28, 2026, ranked Georgia, Wyoming and Nevada ahead of Florida and Texas when all taxes factor in. Wyoming posted the lightest overall burden with its 0.53% effective property rate, low sales tax and absence of estate tax.

South Dakota and Nevada also scored high for combining no income tax with restrained property levies. Florida’s homestead exemption helps, but rising insurance costs linked to hurricane risk have eroded some of its appeal, the Yahoo Finance piece noted.

Advisers caution against chasing tax savings in isolation. Healthcare access, cost of living, climate and proximity to family often outweigh marginal tax differences. Rural states like Wyoming and South Dakota offer low burdens but fewer specialists within easy reach. Florida draws millions precisely because of its established retiree infrastructure despite higher property insurance in vulnerable zones.

Planning adds another layer. Retirees with large traditional balances face required minimum distributions starting at age 73. Those distributions count as ordinary income federally and, in most states, at the state level too. Moving before RMDs begin can lock in years of tax-free growth or withdrawals in a zero-income-tax state.

Roth conversions complicate the math further. Paying federal tax now to shift assets into a Roth account can make sense if the retiree expects to live in a high-tax state later or wants to leave tax-free assets to heirs. But the upfront federal hit requires liquidity many near-retirees lack.

State rules evolve. Iowa’s 2023 expansion for those 55 and older and Michigan’s phased deduction both arrived through targeted legislation aimed at retaining older residents. Pennsylvania and Mississippi have long protected retirement income to attract fixed-income households.

Illinois stands out for its flat rate paired with the full exemption. The policy appeals to pension-heavy public-sector retirees who might otherwise face double taxation on wages earned elsewhere.

Consultants at the Tax Foundation and state revenue departments emphasize one constant. No single list fits every retiree. A couple with $80,000 in annual Social Security and pension income sees different outcomes than one drawing $300,000 from multiple IRAs. Property ownership amplifies differences. A $500,000 home in Texas generates a noticeably higher annual tax bill than the same house in Florida or Nevada.

Still, the directional signal remains strong. States that forgo income tax on retirement distributions give their residents an immediate and visible advantage. For those able to relocate, the decision can preserve hundreds of thousands of dollars over two or three decades.

Planners recommend modeling scenarios with current brackets, projected RMDs and inflation adjustments. Tools from CountryTaxCalc and similar sites let users input specific income sources and home values. The exercise often reveals that total tax burden, not any single line item, determines the winner.

In the end the map shows clear clusters. The Mountain West and South dominate the no-tax list. The Midwest offers targeted carve-outs that rival them for many households. And policy makers continue to tweak incentives as competition for retiree spending intensifies.

Retirees who understand the distinctions hold the upper hand. They convert tax policy from an afterthought into a planning lever. In an era of longer lifespans and rising healthcare costs, every preserved dollar counts.
