State Income Tax Overview

Which states have income tax, how rates vary, residency rules, and how to handle multi-state filing.

TL;DR

  1. 01Nine states have no individual income tax, including Florida, Texas, and Nevada.
  2. 02Compare progressive and flat state rates before assuming your tax bill.
  3. 03File returns in both states and claim a credit for cross-state work.

Tips

  1. 01File an exemption certificate with your employer in reciprocity states so they withhold for your home state only.
  2. 02Check whether your new state exempts pension, Social Security, or IRA income before assuming a move will lower your tax bill.
  3. 03Use a resident-state credit to avoid double taxation whenever you work in a state different from where you live.

Warnings

  1. 01Moving to a no-income-tax state doesn't eliminate all tax. Washington's capital gains tax and New Hampshire's investment income tax still apply to certain income types.
  2. 02High-tax states like New York and California aggressively audit people who claim a domicile change. Keep a day count log and document your new ties.

How State Income Tax Rates Work

States use several rate structures. Progressive states have multiple brackets like the federal system; flat tax states apply one rate to all income.

StateStructureTop Rate (2026)
CaliforniaProgressive13.3%
HawaiiProgressive11.0%
New YorkProgressive10.9%
MassachusettsFlat + surtax9.0% on income over $1M; 5% otherwise
ArizonaFlat2.5%
ColoradoFlat4.4%
IllinoisFlat4.95%

Many states start with your federal AGI or taxable income and make adjustments — adding back deductions disallowed at state level or subtracting state-specific exclusions like pension income or Social Security benefits.

Residency and Domicile Rules

States use two concepts to determine your tax obligations: domicile (your permanent legal home) and statutory residency (spending enough days in a state to trigger resident-level tax regardless of domicile).

  • Domicile: The state where you intend to return and remain indefinitely. You can only have one domicile at a time. Changing domicile requires affirmative steps: new driver's license, voter registration, updating estate documents, and spending more time in the new state.
  • Statutory resident: Most states tax you as a resident if you maintain a permanent place of abode AND spend more than 183 days in the state, regardless of where you're domiciled.

Working in Multiple States

If you work in a state other than where you live, you typically owe income tax to both states. To prevent double taxation, your resident state usually allows a credit for taxes paid to the non-resident state.

Travel employee in multiple statesEach state where work performedResident state credits all

Remote work has complicated state taxes significantly. California, for example, taxes income of non-residents who perform services for California-source clients. The rules vary widely by state and should be verified annually for remote workers.

Reciprocity Agreements

Reciprocity agreements between neighboring states allow residents to pay income tax only to their home state even when they work across the border, simplifying filing and avoiding the need to claim cross-state credits.

WisconsinIllinois, Indiana, Kentucky, Michigan

To use a reciprocity agreement, you must file an exemption certificate with your employer so they withhold for your home state only. Without that form, your employer must withhold for the state where work is performed, and you'll need to file for a refund from the work state.
