Why State Taxes Matter for Retirement and Relocation
State taxes can make a six-figure difference in your lifetime wealth. A couple earning $150,000 in retirement income could pay anywhere from $0 to over $12,000 per year in state income tax alone — depending entirely on where they live. Over a 25-year retirement, that difference compounds to $150,000-$300,000 in purchasing power.
But income tax is only part of the equation. States that charge no income tax often compensate with higher property taxes, sales taxes, or both. A comprehensive comparison must account for all three.
Income Tax Is Not Everything
Nine states charge no income tax: Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming. This makes them magnets for retirees and high-income earners. However, the total tax picture is more nuanced:
- Texas has no income tax, but its median effective property tax rate is 1.68% — one of the highest in the nation. On a $400,000 home, that is $6,720 per year.
- Washington has no income tax but charges a 6.5% state sales tax plus an average 2.37% local rate, totaling 8.87% — among the highest combined rates.
- New Hampshire has no income tax and no sales tax, but its property tax rate of 1.86% is the third-highest in the country.
- Florida is often the best overall option for retirees — no income tax, moderate property taxes (0.89%), and a reasonable combined sales tax rate (7.05%).
Social Security Exemption: 42 States + DC Do Not Tax It
For 2026, the vast majority of states (42 plus the District of Columbia) do not tax Social Security benefits from state income tax. For a retiree collecting $30,000 per year in Social Security, living in an exempt state means that income is entirely state-tax-free.
The eight states that still tax Social Security in 2026 — Colorado, Connecticut, Minnesota, Montana, New Mexico, Rhode Island, Utah, and Vermont — typically offer partial exemptions, and most exempt benefits entirely for lower- and middle-income retirees. Kansas, Missouri and Nebraska stopped taxing benefits in 2024, North Dakota in 2021, and West Virginia completed its phase-out for 2026. The calculator does not model those partial exemptions, so when you enter Social Security it marks the eight taxing states' income tax as not estimated rather than taxing the full benefit. Pensions and IRA withdrawals are excluded where we have read the state's rules (Illinois, Pennsylvania, Mississippi and Iowa so far); for other income-tax states they make the income tax not estimated.
No-Income-Tax Gotchas: Property Tax Offsets
The most common mistake in state tax planning is comparing income tax alone. Consider these examples:
- A homeowner with a $500,000 house in New Jersey (income tax state) pays about $10,900 in property tax. In Texas (no income tax), that same home costs $8,400 in property tax. The income tax savings may be partially eaten by higher property taxes.
- Oregon charges no sales tax, which can save a family spending $40,000 per year on taxable goods roughly $3,820 compared to Tennessee at 9.55%, the Tax Foundation's 2024 average combined rate, which this calculator uses (food is taxed at a lower rate there). But Oregon has a top income tax rate of 9.9%.
Timing Your Move: Tax Year Boundaries
If you are planning a state-to-state relocation, timing matters. Most states tax you as a resident for the portion of the year you lived there. Moving on January 1 gives you a clean break. Moving mid-year means filing part-year returns in both states — manageable but more complex.
Some high-tax states (notably California, New York, and New Jersey) are known for aggressive residency audits of high-income departures. Keep meticulous records: update your driver's license, voter registration, and mailing address. Spend the majority of the year in your new state. Document your physical presence with cell phone records, credit card statements, and travel logs.
Frequently Asked Questions
Which states have no income tax?
Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming — nine states total. New Hampshire eliminated its interest and dividends tax effective 2025.
Which states tax Social Security benefits?
For 2026, eight states: Colorado, Connecticut, Minnesota, Montana, New Mexico, Rhode Island, Utah, and Vermont. Most offer partial or full exemptions for lower-income retirees.
How much can I save by relocating?
It depends on your income, income type, home value, and spending. Use the calculator above to model your specific scenario. With a pension or IRA withdrawals, it estimates income tax for 13 of the 50 states and DC so far; it names any other state as not estimated and shows no saving against it.
Do I need to establish residency?
Yes. You must establish domicile in the new state: update your driver's license, voter registration, and mailing address. Spend the majority of the year in the new state. High-tax states audit departing residents, so maintain documentation.
Does this calculator include federal taxes?
No. This calculator focuses exclusively on state-level taxes (income, property, and sales). Federal taxes are the same regardless of which state you live in. For federal tax planning, see our Roth Conversion Calculator and Retirement Calculator.
