What State Tax Withholding Is
State tax withholding is money your employer takes from your paycheck and sends to your state government on your behalf. It is an advance payment toward the state income tax you will owe when you file your tax return at the end of the year. Most states that have an income tax require employers to withhold it, just as the federal government requires federal withholding.
The amount withheld depends on three things: your gross pay, the tax rates in your state, and the information you provide on a form called a W-4. Your employer does not decide how much to take—you tell them through that form, and they follow your instructions. If you withhold too much, you get a refund when you file. If you withhold too little, you may owe money.
Not all states have income tax. Nine states—Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, Wyoming, and New Hampshire (which taxes only dividends and interest)—do not withhold state income tax at all. If you live or work in one of those states, you will not see state withholding on your pay stub.
Key Takeaways
- State tax withholding is money your employer removes from your paycheck and sends to your state, not money you pay directly.
- You control how much is withheld by filling out a W-4 form when you start a job or whenever your situation changes.
- Nine states do not have income tax and do not require withholding, though some tax specific types of income.
- If too much is withheld, you receive a refund when you file your state return; if too little, you may owe the state money.
- Your pay stub shows the state withholding amount separately from federal withholding and other deductions.
How Your Employer Calculates State Withholding
Your employer uses the W-4 form you completed to calculate withholding. The form asks for your filing status (single, married, head of household), the number of dependents you claim, and whether you have other income or jobs. Based on those answers and your state's tax tables, the employer's payroll system calculates what percentage of your pay to withhold.
The calculation is straightforward: if your state's tax rate is 5 percent and you earn $2,000 in a pay period, the withholding would be roughly $100 (before any deductions or credits are applied). Your employer sends that $100 to your state revenue department, along with withholding from all their other employees. The state holds the money until you file your return and either applies it to what you owe or refunds the overage.
Some states have local income taxes in addition to state tax. Cities in Ohio, Pennsylvania, Kentucky, and a few other states impose local withholding on top of state withholding. Your pay stub will show both separately. Local withholding goes to your city or county, not to the state.
When to Update Your W-4 Form
You fill out a W-4 when you are hired, but you can change it anytime your situation changes. Common reasons to update it include getting married or divorced, having a child, taking a second job, or your spouse starting work. If you do not update it when circumstances change, you may withhold the wrong amount for months or even years.
You should also update your W-4 if you received a large refund or owed a large amount when you filed your last return. A big refund means you withheld too much; a big bill means you withheld too little. Adjusting your W-4 lets you spread the correct amount across your paychecks instead of waiting until tax time to settle up.
Ask your employer's payroll or human resources department for a new W-4 form. Many employers now offer online portals where you can update your withholding without printing anything. The change usually takes effect on your next paycheck, though some employers process changes on a schedule.
Reading Your Pay Stub
Your pay stub breaks down every deduction from your paycheck. Look for a line labeled "state tax," "state withholding," or "ST" (the exact label varies by employer and state). That number is what your employer withheld for state income tax that pay period. Below it, you should see a year-to-date total showing how much has been withheld since January 1.
Do not confuse state withholding with federal withholding—they are separate lines. Federal withholding is usually larger because federal tax rates are higher. You may also see lines for Social Security, Medicare, local tax, and voluntary deductions like health insurance or retirement contributions. Each one comes out before you receive your net pay (the amount you actually take home).
If you notice state withholding is missing from your pay stub and you live in a state with income tax, contact payroll when ready. It may be an error, or it may mean your W-4 was not processed correctly when you were hired.
What Happens at Tax Time
When you file your state income tax return, you report all the state withholding your employers took during the year. The state compares that total to what you actually owe based on your income, deductions, and credits. If you withheld more than you owe, the state refunds the difference. If you withheld less, you pay the remaining balance.
The refund or bill appears on your state return. Some states allow you to have a refund deposited directly to your bank account, just like federal refunds. Others mail a check. If you owe, you can usually pay online through your state's revenue website, by mail, or through your tax software.
Keep in mind that state withholding is not the only thing that determines whether you owe or get a refund. Your total tax bill depends on your income, filing status, dependents, deductions (standard or itemized), and any tax credits you are may have access to to. Withholding is just the down payment.
States Without Income Tax and Special Cases
If you live in Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, or Wyoming, your employer will not withhold state income tax because those states do not have one. You will not see a state withholding line on your pay stub. New Hampshire does not tax wages, but it does tax dividends and interest income, so if you have investment income, you may owe New Hampshire tax even though nothing is withheld from your paycheck.
If you work in one state but live in another, withholding rules depend on where you work. Most states withhold based on the state where the job is located. However, some states have reciprocal agreements that let you withhold for your home state instead. If you commute across a state line, ask your employer's payroll department which state they withhold for and whether you can request a change.
Remote workers should also check their state's rules. Some states withhold based on where the employee lives, not where the company is located. If you moved during the year or took a remote job in a different state, you may need to update your W-4 or file a return in a state where you did not work.
Common Mistakes and How to Avoid Them
The most common mistake is not updating your W-4 when your life changes. People get married, have children, or take second jobs and forget to tell their employer. Months later, they discover they are withholding the wrong amount. Update your W-4 within a few weeks of any major change—do not wait until tax time.
Another mistake is claiming too many allowances or dependents on your W-4 to reduce withholding. While you can adjust your withholding, claiming dependents you do not have is tax fraud. Claim only the dependents you actually support. If you want to reduce withholding for a legitimate reason (like having a spouse who works), adjust your filing status or other entries instead.
A third mistake is ignoring a large refund or bill. If you got a $3,000 refund last year, that means you gave the state an interest-free loan all year. Adjust your W-4 to withhold less so you keep more of your paycheck. Conversely, if you owed $2,000, you withheld too little and should increase your withholding to avoid owing again.
Frequently Asked Questions
Can I claim zero withholding on my W-4 to take home more money?
You can adjust your withholding, but claiming zero when you actually owe tax means you will owe a large bill at tax time—possibly with penalties. If you want more money in each paycheck, adjust your W-4 to withhold less, but make sure you are still withholding enough to cover what you will owe. Your state's revenue website usually has a withholding calculator to help you get it right.
What if I work in one state but live in another?
Your employer typically withholds for the state where you work. However, some states have reciprocal agreements that allow you to withhold for your home state instead. Contact your employer's payroll department to ask whether your situation qualifies. You may also need to file a return in your home state even if you did not work there.
Do I get a refund if I withheld too much state tax?
Yes. When you file your state return, the state compares your total withholding to what you owe. If you withheld more, you receive a refund. The refund is usually deposited to your bank account or mailed as a check, depending on your state's process and how you filed.
Why is my state withholding different from my federal withholding?
State and federal tax rates are different, and some states have lower rates than others. Additionally, some deductions and credits explore to federal tax but not state tax, or vice versa. Your W-4 controls both, but the calculations are separate, so the amounts will rarely match.
What happens to my state withholding if I get a refund on my federal return?
State and federal withholding are completely separate. A federal refund has no effect on your state withholding or your state return. You file both returns independently, and each one calculates whether you withheld enough based on that state's or the federal government's tax rules.
