Quick Read

• South Dakota has a cost-of-living index of 89, which is the lowest among no-income-tax states, allowing a middle-earner couple to retire on roughly $600,000 at a 4% withdrawal rate.

• Florida and Texas homeowners insurance can double over five years after a storm cycle, erasing income tax savings no withdrawal-rate calculator captures.

• Tennessee ranks as the runner-up for warmer-climate retirees; Wyoming suits those with large estates who can tolerate limited healthcare access.

The pitch is intoxicating in its simplicity: skip states with an income tax, keep more of your retirement dollars. 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 hit every year, whether markets are up or down.

This piece walks through no-income-tax states, prices the parts most 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 2025 State Tax Competitiveness Index, is Wyoming, South Dakota, Alaska, Florida, Nevada, Tennessee, Texas, Washington, and New Hampshire. Washington taxes certain capital gains, and New Hampshire phased out its interest and dividends tax, but neither imposes a general wage or retirement income tax.

The Bureau of Economic Analysis puts regional price parities in stark relief. Florida sits at a cost-of-living index of 103.414, Washington at 107.013, New Hampshire at 104.165, Alaska at 102.359, and Nevada at 99.979, all at or above the national benchmark of 100. Texas comes in at 97.057, Tennessee at 91.87, Wyoming at 92.691, and South Dakota at 88.586, 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 break offsets that structurally.

Where the Cost Picture Falls Apart

Florida is where most retirees start and, for many, where they should probably stop. 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, with a property tax rank of 40 in the 2025 index, reflecting 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 39th in property tax, and its effective rates are among the highest in the country. Alaska adds the challenges of distance from specialty medical care and a food-import premium. Nevada looks reasonable on property tax, ranking 7th, but it leans hard on sales tax, and its treatment of groceries and prescriptions is not as friendly as retirees tend to assume. Tennessee has a low cost of living and moderate property taxes, but the combined state and local sales tax on nearly every purchase, including groceries, quietly chips away at the income tax savings you thought you were getting.

Wyoming is an interesting near-miss. Real income of $93,438 is the strongest in the no-income-tax group. Groceries are exempt from state sales tax, and they carry no estate or inheritance tax. But a property tax rank of 44 and thin healthcare access in most of the state hurt a retiree whose medical utilization only rises.

Why South Dakota Actually Works

South Dakota stands out as the real winner here. Its cost of living sits at 88.586, the lowest of any state without an income tax and among the lowest in the country. A property tax rank of 10 in the 2025 index reflects a system with meaningful assessment protections and modest effective rates. There is no estate tax and no inheritance tax to worry about. Homeowners insurance is not exposed to hurricane risk or major wildfire danger, so premiums stay in a normal, predictable band year after year.

For a couple spending roughly $78,535, the 2024 national average annual expenditure, adjusted down by South Dakota's cost index, call the working budget $70,000. Housing at $16,000, including property tax and insurance. Groceries at $9,000, with state sales tax on food as the meaningful drawback. Utilities and transportation at $11,000. Healthcare at $10,000, layered on the 2026 Medicare Part A hospital deductible of $1,736 and standard Part B structure. Miscellaneous, home maintenance, replacement vehicles, and federal tax reserves at $24,000.

Subtract two Social Security checks running with a 3.1% COLA tracking for 2027; call it $48,000 combined for a middle-earner couple. The gap is $22,000. At a 4% withdrawal rate, that requires a $550,000 portfolio. At 3.5%, the safer number for a thirty-year retirement is closer to $630,000. Those are livable targets.

Consideration Most Analyses Miss

A retiree in Florida or Texas can budget every category correctly and still watch homeowners insurance double in a five-year stretch after a bad storm cycle. That single line item, uncorrelated with markets and uncontrollable by the household, is the risk that no withdrawal-rate calculator captures. South Dakota does not have that exposure. The insurance line stays flat, the property tax bill grows slowly, and grocery sales tax is the price of admission for structural stability elsewhere.

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 real assets who values estate treatment and doesn't mind driving for care. But if the question is which single no-income-tax state actually 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.
