Most paychecks have federal income tax withheld, but not all

Whether your paycheck has federal income tax taken out depends on two things: whether you are an employee (not a contractor), and whether you meet the income and filing status thresholds set by the IRS each year. Most W-2 employees do have federal tax withheld. However, some people — typically those with very low annual income — do not owe federal tax and can request that their employer stop withholding it.

The IRS publishes a worksheet each year called the IRS Form W-4, which you fill out when you start a job. This form tells your employer how much federal tax to withhold from each paycheck. If you claim enough allowances or dependents on the W-4, you can reduce or eliminate withholding. But the real question — whether you actually owe federal tax at all — depends on your total income for the year and your filing status.

Key Takeaways

  • Federal income tax withholding is based on the W-4 form you submit to your employer, which estimates your annual tax liability.
  • You do not owe federal income tax if your total income falls below the standard deduction for your filing status, which changes each year.
  • Self-employed people and independent contractors do not have federal tax withheld automatically and must pay estimated taxes quarterly.
  • You can request zero withholding on your W-4 if you expect your income to fall below the standard deduction, but you must update it if your situation changes.
  • The IRS publishes updated standard deduction amounts each year, so the income threshold that determines whether you owe tax shifts annually.

How the standard deduction determines whether you owe federal tax

The standard deduction is the amount of income the IRS allows you to earn tax-free each year. If your total income is below this amount, you do not owe federal income tax. The standard deduction varies by filing status (single, married filing jointly, head of household, and so on) and changes each year.

For example, if you are single and your total income for the year is below the standard deduction, you do not owe federal tax — even if your employer withheld money from your paychecks. In that case, you would file a tax return and receive a refund of the withheld amount. The IRS publishes the current year's standard deduction amounts on its website and updates them annually.

W-4 withholding versus what you actually owe

Your W-4 form is an estimate. It tells your employer how much to withhold based on the information you provide — your filing status, number of dependents, and expected income. But withholding is not the same as what you actually owe in taxes.

If you claim zero allowances on your W-4, your employer withholds the maximum amount. If you claim more allowances, less is withheld. You can also claim "exempt" on the W-4 if you expect to owe no federal tax for the year, which stops withholding entirely. However, if you claim exempt and then earn more than the standard deduction, you will owe tax when you file your return — and you will have no withholding to cover it.

Self-employed and contractor paychecks

If you are self-employed or work as an independent contractor, your paychecks (or invoices) do not have federal income tax withheld at all. Instead, you are responsible for paying estimated quarterly taxes directly to the IRS four times per year. These payments are due on April 15, June 15, September 15, and January 15.

Self-employed people also owe self-employment tax, which covers Social Security and Medicare. This is in addition to federal income tax. You calculate both based on your expected annual income and pay them in quarterly installments. If you do not pay enough throughout the year, you may owe a penalty when you file your annual return.

When to claim exempt or zero withholding

You can request zero withholding on your W-4 if you expect your income to fall below the standard deduction for your filing status. This means no federal tax will be taken from your paychecks. However, the IRS requires you to update your W-4 if your situation changes — for example, if you get a second job or your income increases.

Claiming exempt is different from claiming zero allowances. If you claim exempt, no federal tax is withheld at all. If you claim zero allowances, the maximum amount is withheld based on your income and filing status. You should only claim exempt if you are certain you will owe no federal tax for the year.

Multiple jobs and withholding

If you work more than one job, each employer withholds federal tax based on the W-4 you give them. The problem is that each employer thinks you are earning only from that job, so they may under-withhold when your combined income is higher. This can leave you owing tax at the end of the year.

To fix this, you can claim fewer allowances on one or both W-4 forms, or you can request an additional flat amount be withheld from each paycheck. The IRS Form W-4 includes a line for "other income" and a line for "deductions" that can help you account for multiple jobs. You can also use the IRS withholding calculator on its website to estimate the correct withholding for your situation.

Bonuses, commissions, and supplemental pay

Bonuses and commissions are subject to federal income tax withholding just like regular wages. However, employers have some flexibility in how they withhold on supplemental pay. Some employers withhold a flat 22 percent on bonuses under $1 million. Others withhold based on your W-4 as if the bonus were a regular paycheck spread across the year.

The amount withheld on a bonus is not necessarily the amount you will owe in taxes. If you receive a large bonus, your total income for the year may push you into a higher tax bracket, which means you could owe more than what was withheld. Conversely, if you have other deductions or credits, you might owe less. You will find out the exact amount when you file your tax return.

Frequently Asked Questions

Can I stop federal tax withholding if I do not think I will owe taxes?

Yes, you can claim exempt on your W-4 if you expect your income to fall below the standard deduction. However, you must update your W-4 if your situation changes during the year. If you claim exempt but then earn more than the standard deduction, you will owe tax when you file your return.

What happens if my employer withholds too much federal tax?

If too much federal tax is withheld, you will receive a refund when you file your tax return. The refund is the difference between what was withheld and what you actually owe. You can also adjust your W-4 during the year to reduce withholding if you expect a large refund.

Do I have to file a tax return if no federal tax was withheld?

If your income is below the standard deduction, you are not required to file a federal tax return. However, you may want to file anyway if you had taxes withheld, because you could receive a refund. You may also be may have access to to refundable credits like the Earned Income Tax Credit.

How do I know what the current standard deduction is?

The IRS publishes the standard deduction amounts each year on its website. The amounts depend on your filing status (single, married filing jointly, head of household, and so on) and whether you are 65 or older. You can find the current year's amounts on IRS.gov or ask your tax preparer.

What if I am a contractor — do I need to have federal tax withheld?

No, contractors do not have federal tax withheld by the company that pays them. Instead, you are responsible for paying estimated quarterly taxes to the IRS. You will receive a Form 1099-NEC or 1099-MISC from each client instead of a W-2, and you must report this income on your tax return.
