Frequently Asked Questions
Which states have no income tax?
As of 2025, nine states have no state income tax: Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming. New Hampshire taxes only interest and dividend income, though this is being phased out. Residents of these states still pay federal income tax and may face higher sales or property taxes.
What is the highest state income tax rate?
California has the highest top marginal state income tax rate at 13.3%, which applies to income over $1 million. Other high-tax states include Hawaii (11%), New Jersey (10.75%), and Oregon (9.9%). These top rates only apply to income above their respective thresholds, similar to how federal brackets work.
Do I need to file state taxes if I work remotely?
Generally, you owe state income tax to the state where you physically perform work, which may differ from where your employer is located. Some states have reciprocity agreements that simplify this, while others like New York apply a "convenience of the employer" rule that can tax remote workers. Check your specific state's rules if you work remotely across state lines.
How do state taxes affect my total tax burden?
State income taxes are added on top of your federal tax liability and can significantly increase your overall tax burden. However, you can deduct up to $40,000 in state and local taxes (SALT) on your federal return if you itemize deductions for 2025 ($10,000 for 2024). Your total effective tax rate combines federal, state, Social Security, and Medicare taxes.
