State income tax is withheld from your paycheck at the same time as federal tax, but they are separate calculations and separate payments to different governments

When you look at your pay stub, you will see federal income tax and state income tax listed as separate line items. Both come out of your gross pay before you see your net amount. The order they appear on your stub does not matter — what matters is that your employer sends federal withholding to the U.S. Treasury and state withholding to your state's tax authority, and you owe both.

The two taxes do not reduce each other. You cannot use a federal tax deduction to lower your state tax bill, and you cannot use a state tax deduction to lower your federal bill. Each government calculates what you owe based on its own rules. Some states do allow you to deduct federal income tax paid when you calculate state tax owed, but that happens only at tax time when you file your return — not on your paycheck.

Key Takeaways

  • Federal and state income taxes are withheld separately from your paycheck and sent to different government agencies.
  • Nine states have no state income tax at all, so residents in those states pay only federal withholding.
  • Some states allow you to deduct federal taxes paid on your state return, but this is a filing-time adjustment, not a paycheck deduction.
  • If you work in one state but live in another, you may owe tax to both, and your employer withholds based on where you work.
  • The amount withheld from each paycheck is an estimate; you settle the actual amount owed when you file your return in April.

Which states have no income tax

Nine states do not tax income at all: Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, Wyoming, and New Hampshire. New Hampshire taxes only dividend and interest income, not wages. If you live in one of these states, your pay stub will show federal withholding but no state withholding.

Some of these states make up the lost revenue through sales tax, property tax, or other fees. The total tax burden varies widely depending on how much you earn, where you spend money, and what property you own. Moving to a no-income-tax state does not automatically mean you pay less tax overall.

How withholding works when you live and work in different states

If you live in one state and work in another, your employer withholds based on where you work, not where you live. For example, if you live in New Jersey but work in New York, your employer withholds New York state tax from your paycheck. You then file a return in both states at tax time.

When you file, you report the taxes withheld in the state where you worked. That state gives you a credit for taxes paid there. You then file in your home state and may owe additional tax if your home state's rate is higher. Some states have reciprocal agreements that prevent you from owing tax to both, but these vary by state pair. Check your state's tax authority website for the specific rule that applies to you.

Federal tax does not reduce what you owe in state tax

On your paycheck, federal withholding and state withholding are calculated independently. The federal amount does not reduce the state amount, and vice versa. Your employer calculates each one based on the W-4 form you filled out and the tax tables for each government.

At tax time, some states allow you to deduct federal income tax paid when you calculate your state tax. This is different from paycheck withholding — it is a deduction you claim on your state return. Only about half the states allow this deduction. Check your state's tax forms or website to see whether you can claim it. If you can, it lowers your state tax bill, but only after you have already paid the federal tax through withholding.

What happens if too much or too little is withheld

The amount withheld from each paycheck is an estimate based on the information you provide on your W-4 form. If too much is withheld, you get a refund when you file your return. If too little is withheld, you owe money. This can happen separately for federal and state — you might get a federal refund but owe state tax, or the other way around.

You can adjust your withholding at any time by submitting a new W-4 to your employer. If you expect a large refund or a large bill, changing your withholding mid-year can help you break even by the time you file. The IRS and most state tax authorities have withholding calculators on their websites to help you figure out the right amount.

Self-employed workers and estimated tax payments

If you are self-employed, you do not have an employer to withhold tax for you. Instead, you make quarterly estimated tax payments directly to the federal government and to your state (if your state has income tax). These payments are due on April 15, June 15, September 15, and January 15. You calculate the estimated amount based on your expected income for the year.

Self-employed workers owe both federal and state estimated tax in the same way as wage earners owe withholding — as a prepayment toward the total tax bill. When you file your return, you report what you paid and settle the actual amount owed. If you underpay, you may owe a penalty in addition to the tax itself.

How to check your withholding on your pay stub

Your pay stub shows gross pay, federal withholding, state withholding (if applicable), and other deductions like health insurance or retirement contributions. The federal and state amounts are listed separately. Add them together to see your total tax withholding for that pay period.

Over the course of a year, add up all the federal withholding and all the state withholding from your pay stubs. When you file your return, you will report these totals. If the total withheld is more than what you actually owe, you get a refund. If it is less, you owe the difference. Keep your pay stubs or read them from your employer's payroll system so you have them when you file.

Frequently Asked Questions

Do I have to pay both federal and state income tax?

You owe federal income tax if you earn above a certain threshold, which changes each year based on your age and filing status. You owe state income tax only if your state has an income tax and you earn above that state's threshold. Nine states have no income tax, so residents there owe only federal tax.

Can I claim state taxes paid as a deduction on my federal return?

You can deduct state and local taxes (SALT) on your federal return, but only up to $10,000 per year. This deduction is available only if you itemize deductions instead of taking the standard deduction. For most people, the standard deduction is larger, so they do not benefit from this deduction.

What if my employer withholds the wrong amount of state tax?

If your employer withholds too much, you will get a refund when you file your state return. If too little is withheld, you will owe money. You can adjust your withholding by submitting a new state W-4 form to your employer. Your state's tax authority website has a withholding calculator to help you figure out the correct amount.

Do I owe state tax if I work remotely in a different state?

Generally, you owe tax to the state where you work, not where you live. If you work remotely for a company in another state, you typically owe tax to your home state. However, some states have special rules for remote workers. Check with your state's tax authority for the exact rule, as it can change based on where your employer is located.

Why is my state withholding different from my federal withholding?

Federal and state tax rates are different, and the deductions and credits available in each system are different. Your employer calculates each withholding separately using the tax tables for that government. The federal amount and state amount will rarely be the same, even if your income is the same.
