How to use this state tax calculator
- Enter your annual income and filing status.
- Pick your state from the list.
- The calculator works out a state tax estimate for 2026 and shows the effective rate.
Formula
Taxable income = annual income − the federal standard deduction ($16,100 single / $32,200 married filing jointly / $24,150 head of household in 2026). For California, the estimate uses simplified California brackets on the income left after a $5,700 state deduction ($11,400 married filing jointly). For other states with an income tax, the estimate is a flat rate applied to taxable income — a rough guide, not the real state schedule. The nine states with no income tax — Texas, Florida, Washington, Nevada, Wyoming, South Dakota, Alaska, New Hampshire and Tennessee — come out at $0.
Worked example — $80,000 in California, Texas, Georgia and New York
$80,000 a year, single, leaves $63,900 of taxable income. In California, the simplified brackets give $2,120.80 of state tax (2.65% of income). In Texas and Florida, there is no state income tax, so the answer is $0. In Georgia, the flat-rate estimate at 5.19% is $3,316.41. In New York, the flat-rate estimate at 5.5% is $3,514.50 — state tax only, before any New York City tax. Change the state above to see your own number.

Frequently asked questions
Which states have no income tax?
Nine states have no state income tax on wages: Texas, Florida, Washington, Nevada, Wyoming, South Dakota, Alaska, New Hampshire and Tennessee. Moving to one of them does not remove your federal tax — it only removes the state part.
How much is California state tax on $80,000?
About $2,120.80 a year, single, using the simplified California brackets on this site — 2.65% of income. The real California return uses the full state schedule and your own deductions, so treat this as a rough guide.
Is this state tax figure exact?
No. Outside California it is a flat-rate estimate, and even the California figure uses simplified brackets. Real state tax depends on the state's own brackets, deductions and credits, and on local taxes in some places. Use the number to compare states and to plan, not to file.
Does state tax lower my federal tax?
It can, if you itemize: state and local taxes are deductible on a federal return, capped at $10,000 in most cases. If you take the standard deduction, state tax does not change your federal bill. The standard deduction calculator compares the two.
Do I pay state tax where I live or where I work?
Usually where you live, but it depends on the states involved: some states tax income earned inside their borders, and some have agreements that change the rule. If you live in one state and work in another, ask a tax professional — this calculator cannot cover that case.
