State Income Tax: How Much Depends Entirely on Where You Live
Unlike federal income tax, which applies the same brackets nationwide, state income tax varies enormously depending on where you live and work. Nine states โ including Texas, Florida, Nevada, and Washington โ charge no state income tax on wages at all, while California's top marginal rate reaches 13.3% on the highest earners. Most other states fall somewhere in between, either with a single flat rate (like Colorado's 4.4% or Pennsylvania's 3.07%) or a progressive bracket system similar to the federal structure, where your rate climbs as your income rises. Because bracket structures differ so much from state to state, this calculator uses your state's flat or top marginal rate as a simplified single-rate estimate โ for an exact figure, you'll need your state's specific bracket table or your prior year's effective rate.
Example State Rates
| State | Rate Type |
|---|---|
| Texas, Florida, Nevada, Washington | 0% (no income tax) |
| Pennsylvania | 3.07% flat |
| Colorado | 4.4% flat |
| New York | Up to 10.9% (progressive) |
| California | Up to 13.3% (progressive) |
State income tax is filed on a separate return from your federal taxes, with its own deductions, credits, and filing deadlines โ check your state's department of revenue for the exact rules that apply to you.
