Overtime is taxable income from your first hour worked
There is no threshold at which overtime suddenly becomes taxable. Every dollar of overtime pay is subject to federal income tax, Social Security tax, and Medicare tax the moment you earn it. Your employer withholds taxes on overtime the same way they do on regular pay — based on the tax bracket you fall into and the W-4 form you filed.
The confusion often comes from overtime thresholds themselves. The Fair Labor Standards Act requires employers to pay overtime (time-and-a-half) after 40 hours per week, but that rule is about when you must be paid more per hour, not when that pay becomes taxable. Once overtime pay hits your paycheck, it is treated as ordinary income.
Some workers think overtime is tax-free because they hear about tax-free income in other contexts — gifts, certain scholarships, workers' compensation for injury. Overtime is not in that category. It is wages, and wages are taxed.
Key Takeaways
- Overtime pay is taxable from the first hour you work it; there is no dollar amount or hour threshold that makes it tax-free.
- Your employer withholds federal income tax, Social Security tax (6.2%), and Medicare tax (1.45%) on overtime at the same rates as regular pay.
- The tax you owe depends on your total income for the year and your filing status, not on how many overtime hours you worked.
- Overtime pay may push you into a higher tax bracket, meaning some of your overtime is taxed at a higher rate than your regular hours.
How overtime affects your tax bracket
Overtime can change how much federal income tax you owe because the U.S. uses a progressive tax system. Your income is taxed in layers: the first portion at one rate, the next portion at a higher rate, and so on. When you add overtime hours, you are adding income to the top of that stack, which may push some or all of it into a higher bracket.
For example, if you are single and earn $35,000 in regular pay, you fall into the 12% federal bracket for 2024. If you then earn $5,000 in overtime, that $5,000 is added on top. Part of it may still be taxed at 12%, but the portion that crosses into the next bracket (22%) is taxed at that higher rate. Your employer cannot know this in advance, so they withhold based on what you told them on your W-4.
This is why some workers are surprised at tax time: they expected their overtime to be taxed at one rate, but the actual tax owed is higher because the overtime pushed them into a new bracket. This is not a penalty — it is how the tax system works for all income.
What your employer withholds on overtime
Your employer withholds three types of tax on overtime pay: federal income tax, Social Security tax, and Medicare tax. The Social Security and Medicare portions are fixed percentages that do not change. Social Security is 6.2% of your gross pay (up to a wage cap that changes yearly), and Medicare is 1.45% of all your gross pay with no cap.
Federal income tax withholding is more complicated because it depends on your W-4 form. When you filled out your W-4, you told your employer how many dependents you have, whether you have a second job, and whether you want extra withheld. Your employer uses that information to calculate how much federal tax to take from each paycheck, including overtime.
If your employer withholds too little, you will owe money at tax time. If they withhold too much, you will get a refund. The only way to adjust this during the year is to file a new W-4 with your employer and change your withholding.
Overtime and self-employment versus W-2 work
If you are a W-2 employee, your employer handles all withholding and you do not have to think about it until tax time. If you are self-employed or a contractor, you are responsible for setting aside money for taxes yourself — there is no employer withholding. This means you need to estimate your tax liability and make quarterly payments to the IRS.
Self-employed workers also pay both the employee and employer portions of Social Security and Medicare tax, which totals 15.3% instead of the 7.65% a W-2 employee pays. This is a significant difference and is one reason self-employed income often feels like it is taxed more heavily.
If you have overtime as a W-2 employee and also do self-employed work on the side, you will owe tax on both. The overtime is handled through payroll withholding, but the self-employed income requires you to file Schedule C and pay estimated taxes quarterly.
Bonuses and overtime: how they are taxed differently
Overtime is regular wages and is taxed as such. Bonuses — including holiday bonuses, performance bonuses, and signing bonuses — are also taxable, but employers sometimes withhold at a flat 22% federal rate instead of calculating your actual bracket. This is called the supplemental wage withholding method.
The flat 22% rate is often higher than what you actually owe, which is why many workers get a refund after receiving a large bonus. It is not that bonuses are taxed differently in law; it is just that employers use a simpler withholding method for them.
Overtime, by contrast, is withheld using the same method as your regular pay. There is no special bonus treatment. This means your withholding on overtime is more likely to match what you actually owe, though it still depends on your W-4 accuracy.
What to do if too much or too little is withheld
If you work significant overtime and suspect your withholding is wrong, you can adjust it by filing a new W-4 form with your employer. You do not need to wait until tax time. The form asks you to estimate your total income for the year and tells your employer how much to withhold going forward.
If you are consistently getting large refunds, you are having too much withheld. If you owe money at tax time, you are having too little withheld. Either situation can be fixed by updating your W-4. Some workers use the IRS withholding calculator on irs.gov to estimate what they should claim.
Keep in mind that withholding changes take effect on the next paycheck after your employer processes the new W-4. If you are near the end of the year, there may not be enough time for the adjustment to matter for that tax year.
State and local taxes on overtime
In addition to federal tax, most states tax overtime as ordinary income. A few states have no income tax at all (Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, and Wyoming), so residents of those states owe only federal tax on overtime.
States that do tax income generally use the same progressive bracket system as the federal government, so overtime can push you into a higher state bracket as well. Some cities also tax income — notably New York City and Philadelphia — and overtime is subject to those taxes too.
Your employer should be withholding state and local taxes on your overtime if you live in a state or city that has them. If you work in one state but live in another, the rules become more complex and may require you to file returns in both places. This situation is common for people who live near state borders or work remotely.
Frequently Asked Questions
Is there a dollar amount of overtime that is tax-free?
No. Every dollar of overtime is taxable income. There is no threshold — whether you earn $100 or $10,000 in overtime, all of it is subject to federal income tax, Social Security tax, and Medicare tax. The only income that can be tax-free is money that falls into specific categories like gifts or certain types of scholarships, and overtime does not may have access to.
Why does my overtime paycheck have so much tax taken out?
Overtime often appears to be taxed heavily because it pushes your total income higher, which can move you into a higher tax bracket. Additionally, if your W-4 is not accurate for your situation, your employer may be withholding more than necessary. You can adjust your W-4 to change your withholding, or you may receive the difference back as a refund at tax time.
Do I have to report overtime separately on my tax return?
No. Overtime is included in the total wages your employer reports on your W-2 form in Box 1. You do not itemize overtime separately. You straightforward report the total wages from Box 1 on your tax return, and the IRS taxes it as ordinary income based on your bracket.
What if my employer does not withhold taxes on overtime?
This is illegal. All employers are required to withhold federal income tax, Social Security tax, and Medicare tax on all wages, including overtime. If your employer is not withholding, contact your state labor department or the IRS. You will still owe the tax at the end of the year, and your employer may face penalties.
Can I claim overtime as a deduction?
No. Overtime is income, not a deductible expense. You cannot reduce your taxable income by claiming the hours you worked. The only deductions available to most workers are the standard deduction or itemized deductions, neither of which relates to overtime hours.
