Federal vs State Income Tax
Understand the difference between federal income tax and state income tax in a simple paycheck estimate.
Quick answer
Use this guide as a simple starting point, then compare your numbers with the related TaxMaster calculators below. Calculator results are educational estimates and may differ from your actual tax, payroll, or financial result.
Federal income tax is collected by the U.S. federal government. State income tax, when it applies, is collected by the state where you live or work. Both can affect your paycheck and your estimated salary after taxes.
Federal income tax generally applies nationwide, but state income tax rules vary widely. Some states use progressive tax brackets, some use flat rates, and some do not have a broad wage income tax.
A person earning the same gross salary can have different take-home pay depending on their state. That is why it is useful to compare federal tax separately from state tax.
Payroll taxes such as Social Security and Medicare are different from income tax. They can still reduce your paycheck even if your state has no broad wage income tax.
Use the federal income tax calculator, state income tax calculator, and paycheck calculator together to compare your estimate from multiple angles.
