Frequently Asked Questions
Which states have no income tax?
Nine states have no individual income tax: Alaska, Florida, Nevada, New Hampshire (taxes only interest and dividends, being phased out), South Dakota, Tennessee, Texas, Washington (no wage tax), and Wyoming.
Does state income tax reduce my federal taxable income?
If you itemize deductions on your federal return, you can deduct state and local taxes (SALT) โ but only up to $10,000 total. This cap was established by the Tax Cuts and Jobs Act and remains in effect for 2025.
Are state tax rates the same for all income levels?
It depends on the state. Some states like Illinois and Pennsylvania use a flat rate for all income. Others like California and New York use progressive brackets similar to the federal system.
Do I pay state income tax in the state where I live or where I work?
Generally both โ you owe tax to your resident state on all income and to your employer state on income earned there. Many states have reciprocal agreements that prevent double taxation for cross-border workers.
Is this state tax estimate accurate for my situation?
This calculator provides a simplified estimate based on each state's top-level rate structure. Actual state taxes may vary due to state-specific deductions, credits, exemptions, and local taxes. Always verify with your state's official tax authority.
