State Income Tax Systems in 2026
States use three approaches: progressive brackets (like federal tax — higher income taxed at higher rates), flat tax (one rate for everyone), or no income tax. Nine states have no income tax at all. The variation is enormous — a $100,000 earner pays $0 in Texas but over $6,000 in California.

Frequently Asked Questions
Which state do I file in if I moved?
You typically file a part-year return in each state, paying tax on income earned while a resident. Some states have different rules for remote workers, and a few tax all income if you spent any part of the year as a resident.
Do I pay both state and federal tax?
Yes — state income tax is separate from and in addition to federal tax. However, you can deduct up to $10,000 of state and local taxes (SALT) on your federal return if you itemize.
Which states have no income tax?
Nine states have no state income tax: Alaska, Florida, Nevada, New Hampshire (dividends/interest only until 2027), South Dakota, Tennessee, Texas, Washington, and Wyoming. However, these states often have higher sales or property taxes to compensate. Consider total tax burden, not just income tax, when comparing states.
