Your take-home pay depends heavily on where you work — state income tax ranges from 0% in nine states to over 10% at the top in California, New York and New Jersey. Pick your state for a paycheck calculator pre-loaded with its 2025 income-tax rules, plus federal tax, Social Security, Medicare and 401(k).
Two people earning the same salary can take home very different amounts depending on the state they work in. Federal income tax, Social Security and Medicare are identical nationwide, but state income tax is not. Nine states — Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington and Wyoming — levy no income tax on wages at all, so workers there keep more of every paycheck. Most other states use either a single flat rate (like Pennsylvania's 3.07% or Illinois's 4.95%) or graduated brackets that rise with income (topping out above 10% in California, New York, New Jersey and Hawaii). On a typical salary that difference can be worth several thousand dollars a year.
Each calculator on this page is pre-loaded with that state's 2025 income-tax structure and combines it with current federal brackets, the $184,500 Social Security wage base and Medicare rates to show your real net pay per paycheck and per year. Adjust your salary, pay frequency, filing status and 401(k) rate to match your situation. These tools are ideal for comparing job offers across states, planning a move, or simply understanding the gap between your gross salary and what actually hits your bank account. They cover state-level taxes only — local city or county income taxes, which exist in places like New York City, Philadelphia and parts of Ohio, are not included, so always confirm your exact withholding with your employer.

The states do not share a single approach to taxing wages, and the calculators here reflect three genuinely different regimes. Nine states levy no tax on wage income at all; fifteen apply a single flat rate to everything above their thresholds; and twenty-seven, along with the District of Columbia, run graduated brackets. Which category a state falls into changes not just how much is withheld but how the amount responds to a raise.
That distinction matters most at the margin. Under a flat rate, an extra dollar earned is taxed exactly like the first; under graduated brackets it is taxed at the top rate you reach, which at the upper end means 12.3% in California, 11% in Hawaii and 10.9% in New York. The frequent misunderstanding is that crossing a bracket re-taxes everything below it — it does not, since only the income inside each band is taxed at that band's rate, which is why a raise can never reduce take-home pay.
Federal payroll deductions behave the same way in every state, which is what makes the state layer the interesting variable. Social Security is withheld at a fixed rate up to an annual wage base and stops for the rest of the year once that ceiling is passed; Medicare has no ceiling and adds a surcharge above a threshold. Because those rules are national, two people on identical salaries in different states differ in take-home pay almost entirely because of state income tax and any local tax on top of it.
These calculators are deliberately simplified, and the simplifications are worth knowing before relying on a figure. They model state income tax on wages using published state parameters and do not attempt local or city income taxes — which are significant in places such as New York City and Philadelphia — nor credits, phase-outs, or the many pre-tax deductions an individual payslip may carry. The result is a sound planning estimate and a good way to compare states; it is not a substitute for your actual withholding or for advice on your own return.
