Enter income, a U.S. state and filing status to view estimated tax, monthly amount and income after state tax.
Choose the state and income basis
Enter annual income, then select the state and filing status used by the planning model. Residency, work location, and reciprocity require separate review.
How the estimate is produced
For progressive states, the calculator applies one simplified top marginal rate to all entered income. It does not calculate brackets, deductions, credits, surtaxes, or local taxes and is not an effective-rate estimate.
Reading the result
The result shows annual tax, a monthly equivalent, the effective modeled rate, and income after only this modeled state tax. It is not a complete take-home-pay calculation.
Important limits
Progressive brackets, deductions, credits, surtaxes, local taxes, federal tax, payroll tax, and reciprocity are excluded. Use current official state guidance before making filing decisions.
Frequently Asked Questions
Which state determines my state income tax?
Residency, work location, income source, and reciprocity agreements can all matter. This calculator uses the state you select and does not determine legal filing obligations.
Which states have no individual wage income tax?
States marked as no-wage-income-tax in the centrally dated 2026 dataset produce a zero estimate. Other state taxes and filing duties may still apply.
How do progressive state brackets work?
For progressive states, the calculator applies one simplified top marginal rate to all entered income. It does not calculate brackets, deductions, credits, surtaxes, or local taxes and is not an effective-rate estimate.
Are local income taxes included?
No. City, county, school-district, and other local income taxes are excluded, as are federal income tax and payroll tax.
How do filing status and deductions affect the result?
