Alaska, Florida, Nevada, New Hampshire (dividends and interest only), South Dakota, Tennessee, Texas, Washington, and Wyoming have no state income tax on wages. Enter 0% for these states.
Is this calculator accurate for progressive state tax brackets?
This tool uses a flat rate approximation. States with graduated brackets (e.g., California, New York) have multiple rates. Use your effective state rate for the best estimate, or the top marginal rate for a conservative figure.
Can I deduct state taxes on my federal return?
Yes, if you itemize. The SALT (state and local tax) deduction is currently capped at $10,000 per year for federal purposes under the Tax Cuts and Jobs Act provisions.
