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.
