Let’s Be Real. For Most Retirees, Only One No Income Tax State Actually Works

The pitch is intoxicating in its simplicity: skip states with an income tax, keep more of your retirement dollars. But a state with no income tax still funds schools, roads, and Medicaid somewhere else. For retirees living on Social Security and moderate portfolio distributions, that somewhere else is usually a property tax bill, homeowners insurance premium, or sales tax on groceries. Those costs hit every year, whether markets are up or down.

This piece walks through every no-income-tax state, prices the parts most retirement calculators ignore, and identifies which one actually works.

Nine States, One Real Answer

The current list of states with no broad individual income tax, per the 2026 State Tax Competitiveness Index, is Wyoming, South Dakota, Alaska, Florida, Nevada, Tennessee, Texas, Washington, and New Hampshire. Washington taxes certain capital gains. New Hampshire completed the full repeal of its interest and dividends tax on January 1, 2025, which vaulted it to third overall on the 2026 index, but neither state imposes a general wage or retirement income tax.

The Bureau of Economic Analysis puts regional price parities in stark relief using its 2024 data. Florida sits at a cost-of-living index of 103.4, Washington at 107.0, New Hampshire at 104.2, Alaska at 102.4, and Nevada at 100.0, all at or above the national benchmark of 100. Texas comes in at 97.1, Wyoming at 92.7, Tennessee at 91.9, and South Dakota at 88.6, the lowest of the group. A retiree in a 103-index state pays more for the same basket of goods than a retiree in an 88-index state, and no income tax savings offset that structural gap over a multi-decade retirement.

Where the Cost Picture Falls Apart

Florida is where most retirees start, and for many, it is where the math first breaks down. Homeowners insurance in both coastal and inland Florida has become the decisive line item, with hurricane deductibles functioning like a second annual bill. Texas has a similar problem: a property tax rank of 38 in the 2026 index reflects effective rates near the top of the country, so even a paid-off Texas home still comes with a substantial annual bill.

Washington and New Hampshire fail the cost-of-living test outright. New Hampshire ranks 44th in property tax on the 2026 index, and its effective rates are among the highest in the country, a burden that no income tax exemption can fully offset. Alaska adds the challenges of distance from specialty medical care and a food-import premium that inflates the grocery bill year-round. Nevada looks reasonable on property tax, ranking 7th, but it leans heavily on sales tax, and its treatment of groceries and prescriptions is less friendly to retirees than it first appears. Tennessee has a genuinely low cost of living and moderate property taxes, but the combined state and local sales tax on nearly every purchase, groceries included, quietly erodes the income tax savings.

Wyoming is an interesting near-miss. Real per-capita income is the strongest in the no-income-tax group. Groceries are exempt from state sales tax, and the state carries no estate or inheritance tax. A property tax rank of 37 on the 2026 index is a genuine improvement from prior years. The remaining obstacle is healthcare: thin access to specialty care across most of the state is a real cost for any retiree whose medical utilization only rises with age.

Why South Dakota Actually Works

South Dakota stands out as the clear winner. Its cost-of-living index sits at 88.6, the lowest of any state without an income tax and among the lowest in the country. A property tax rank of 8 in the 2026 index reflects a system with meaningful assessment protections and modest effective rates. There is no estate tax and no inheritance tax. Homeowners insurance carries no hurricane or major wildfire exposure, so premiums stay in a normal, predictable band from one year to the next.

For a couple spending roughly $78,535 (the 2024 national average annual expenditure), adjusting down by South Dakota’s cost index puts the working budget around $70,000. Housing runs about $16,000, including property tax and insurance. Groceries come to roughly $9,000, and state sales tax on food is the meaningful drawback here. Utilities and transportation total around $11,000. Healthcare lands at about $10,000, layered on top of the 2026 Medicare Part A hospital deductible of $1,736 and the standard Part B structure. Miscellaneous spending, home maintenance, eventual vehicle replacement, and federal tax reserves account for the remaining $24,000.

Subtract two Social Security checks, with the SSA’s official 2027 COLA set at 3.6%, and a middle-earner couple can reasonably count on around $48,000 combined. The gap is $22,000. At a 4% withdrawal rate, covering that gap requires a $550,000 portfolio. At 3.5%, the safer number for a thirty-year retirement stretches closer to $630,000. Both are achievable targets for a household that planned consistently.

The Consideration Most Analyses Miss

A retiree in Florida or Texas can budget every category correctly and still watch homeowners insurance double over a five-year stretch after a bad storm cycle. That single line item is uncorrelated with markets and entirely outside the household’s control. No withdrawal-rate calculator captures it. South Dakota does not carry that exposure. The insurance line stays flat, the property tax bill grows slowly, and grocery sales tax is simply the price of admission for structural stability everywhere else.

Tennessee is the clear runner-up for retirees who want a warmer climate and better access to major medical systems. Wyoming works for someone with meaningful assets who values estate treatment and does not mind driving for care. But when the question is which single no-income-tax state holds up once the full carrying cost of retirement is priced in, the answer is South Dakota. A portfolio in the $550,000 to $650,000 range, two Social Security checks, a paid or nearly paid home, and a 3.5% withdrawal rate make the scenario real for a wide band of middle-income retirees.
