which states have no income taxes at all?

Direct answer: As of 2025, nine U.S. states do not impose a personal income tax: Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming. Note that some of these states still collect other taxes (like sales or property taxes) to fund government services, and in Washington there is a capital gains tax on certain high-end gains. Results may vary slightly depending on whether you count New Hampshire’s interest and dividend tax changes that phased in earlier years; in 2025 New Hampshire generally treats interest and dividends differently than earned wages. The list below reflects the states with no broad personal income tax in 2025.
