2026 State Income Tax Calculator
Choose where you live and enter projected state taxable income — the amount after that state’s additions, subtractions, deductions, and exemptions. The tool applies the selected 2026 state rate schedule and names important exclusions instead of treating federal income as automatically identical.
Includes all 50 states and the District of Columbia. Residency, part-year, and multistate sourcing rules are not determined by this selection.
Use the schedule shown on your state return. Head-of-household and separate-return schedules require the state form and are not approximated here.
Use the taxable-income line produced by your state worksheet, after state-specific modifications and deductions — not gross freelance revenue.

How this calculator works
- Use the 2026 single or married-joint rate schedule published for the selected state or Washington, D.C.
- Apply each marginal rate only to the portion of entered state taxable income inside that bracket.
- Show the published standard deduction as context, but do not subtract it again because the input is already state taxable income.
- Divide the pre-credit annual estimate by four only as a cash-reserve planning amount, not as a state safe-harbor calculation.
What the result does not include
- The input must come from the selected state’s taxable-income worksheet; gross revenue, Schedule C profit, federal AGI, and federal taxable income are not interchangeable.
- Credits, benefit recapture, alternative taxes, part-year or nonresident sourcing, capital-gains preferences, and state-specific entity taxes are excluded.
- City, county, occupational, and payroll taxes are not calculated. The result warns when a local income-tax layer commonly applies.
- Only the single and married-joint schedules are calculated; other filing schedules must use the current state form.
Common questions
Why does the calculator ask for state taxable income?
States do not all begin with the same federal line, and each has its own additions, subtractions, deductions, exemptions, and conformity rules. Asking for the state taxable-income line prevents the tool from silently applying a deduction twice or assuming that federal AGI equals the state tax base.
Does this include city or county income tax?
No. The result identifies states where a local layer commonly exists, but a ZIP code or city would be needed to calculate it. Maryland counties, New York City, many Pennsylvania municipalities, and numerous Ohio cities are examples where the local amount can be material.
Does the quarterly reserve equal the required state payment?
Not necessarily. It is one fourth of the pre-credit annual estimate. State safe-harbor percentages, withholding, prior-year tax, unequal installment schedules, and payment thresholds vary. Use the selected state’s estimated-tax form to determine the required payment.
Can the result be used to file a state return?
No. It applies the published rate schedule to taxable income for planning. Credits, recapture rules, residency and sourcing, special deductions, alternative taxes, and local taxes can change the filed amount.
