You just finished a sixty-hour week. You’re exhausted, your feet ache, but that paycheck looks beautiful. Then you see the withholding. It feels like the government took a massive bite out of your hard-earned extra hours before you even saw a dime. It’s enough to make anyone wonder if picking up that extra shift was even worth it. Honestly, it’s the most common gripe in breakrooms across the country.
There is a persistent myth that overtime pay is "taxed more" than your regular hours. You’ve probably heard a coworker say it. They swear that because they worked ten hours of OT, they got bumped into a higher bracket and actually took home less money than if they had stayed home and watched Netflix.
That’s basically impossible. But the reason people believe it is rooted in how payroll software actually functions.
The Mystery of Overtime Withholding vs. Actual Tax
To answer the big question: will overtime be taxed at the end of the year differently than your normal salary? The short answer is no. At the end of the year, the IRS doesn't care if a dollar came from your first forty hours or your fiftieth. It’s all just "Ordinary Income."
However, your withholding is a different story.
When you work a ton of overtime in a single pay period, your payroll system looks at that specific check and makes a wild assumption. It assumes you are going to make that much money every single week for the entire year. If you usually make $1,000 a week but one week you make $2,000 because of a massive project, the computer thinks you’ve suddenly jumped from a $52,000-a-year salary to a $104,000-a-year salary.
Because we have a progressive tax system in the U.S., higher income is taxed at higher marginal rates. The payroll software panics. It withholds taxes at the rate for someone making six figures. That’s why your check looks so small relative to the effort you put in. But—and this is the crucial part—that money isn't "gone." It’s just sitting with the IRS until you file your return.

The Progressive Bracket Reality
Think of tax brackets like buckets. The first bucket is taxed at 10%. Once that’s full, the next dollar goes into the 12% bucket. Then 22%, and so on.
- 10% Bracket: Up to $11,600 (for single filers in 2024/2025).
- 12% Bracket: Up to $47,150.
- 22% Bracket: Up to $100,525.
If your total annual income—including every bit of overtime—stays within the 12% bracket, then every single dollar of that overtime is eventually taxed at 12%. If the payroll department took out 22% because of a one-time spike, you’ll get that 10% difference back as a tax refund. You aren't losing money to a higher bracket; you're just giving the government an interest-free loan until April.
Why Your Coworkers Think Overtime is a Scam
There is a psychological trap here. We see the "Net Pay" and we feel the sting.
I once talked to a nurse who refused all holiday overtime because she was convinced she was "working for free" after the 45th hour. She wasn't. She was just seeing the results of the IRS Circular E, which provides the withholding tables employers must use. According to the Tax Foundation, the U.S. tax code is over 6,000 pages long. It's no wonder people get confused.
If you are right on the edge of a tax bracket, your overtime might indeed be taxed at a higher rate. But only the extra money is taxed at that rate. If you jump from the 12% bracket to the 22% bracket, only the dollars above the threshold ($47,150 for singles) are taxed at 22%. Your original earnings are still taxed at the lower rates. You always, always make more money by working more, even if the "rate of return" on your time feels slightly lower.
The Year-End Reckoning
When the clock strikes midnight on December 31st, the IRS looks at your total "Adjusted Gross Income."

This is where the will overtime be taxed at the end of the year question gets settled. Your W-2 will show your total earnings. It doesn't break it down by "regular" vs "overtime." The tax software (or your CPA) will calculate your total liability based on that lump sum.
If you worked a moderate amount of overtime and your employer withheld a ton of tax, you’re looking at a nice refund. If you worked consistent overtime all year and adjusted your W-4 to withhold less, you might break even.
Bonuses and "Supplemental Wages"
Sometimes overtime is lumped in with bonuses. The IRS calls this "supplemental wages." Employers have two choices here:
- The Aggregate Method: They add the extra money to your regular pay and withhold based on the total (this is what usually causes the "over-withholding" shock).
- The Percentage Method: They withhold a flat 22% for federal taxes.
If you’re normally in the 12% bracket, a flat 22% withholding feels like a robbery. Again, it’s not a permanent tax increase. It’s a temporary holding.
Strategies to Manage the Overtime Tax Hit
If you know you’re going to be working a massive amount of overtime this year—maybe you're a first responder or you're in seasonal retail—you don't have to just "deal with it."
First, check your W-4. You can use the IRS Tax Withholding Estimator. It’s a surprisingly decent tool. By adjusting your "Extra Withholding" or claiming additional credits, you can tell your payroll department to take less out of each check. This puts more money in your pocket now, though it reduces your year-end refund.

Second, consider the "401(k) Offset." If you're worried about overtime pushing you into a higher tax bracket at the end of the year, increase your pre-tax retirement contributions. Every dollar you put into a traditional 401(k) lowers your taxable income. It’s like a shield against the tax man. You’re essentially moving money from your overtime "spike" into your future "wealth."
Common Myths That Just Won't Die
"I'll make less money if I work OT." No. Mathematically, this only happens in very specific "welfare cliff" scenarios involving government subsidies (like Earned Income Tax Credit or SNAP benefits) where a small increase in income results in a loss of benefits. For 99% of workers, more hours equals more net wealth.
"Overtime is taxed at 40%." Nope. That’s usually a mix of Federal Tax, State Tax, Social Security (6.2%), and Medicare (1.45%) all being taken out at once. It feels like 40%, but the "tax" part is only one piece of that pie.
What You Should Do Right Now
Don't fear the overtime. Seriously.
If you’re worried about how will overtime be taxed at the end of the year, the best thing you can do is keep a running tally. Look at your year-to-date (YTD) earnings on your pay stub. If you’re approaching a new tax bracket, just be aware of it.
- Review your last three pay stubs. Look at the percentage of federal tax being withheld. If it’s significantly higher than your actual tax bracket (e.g., they are taking 22% but you only make $40k a year), go to HR and update your W-4.
- Open a High-Yield Savings Account. If you get a big tax refund because of overtime withholding, don't treat it like "free money." That was your money all along. Put it somewhere it earns 4% or 5% interest.
- Track your expenses. If you're working extra hours, you might be spending more on convenience (takeout, Uber, etc.). Sometimes the "tax" isn't what eats your overtime; it's the "lifestyle creep" that comes with being too tired to cook.
Overtime is a tool. It's a way to fast-track debt repayment or a house down payment. The IRS takes their cut, sure, but they don't take it all. Understand the difference between withholding and actual tax liability, and you'll stop stressing every time you see a "fat" check with a "lean" take-home. Keep your eyes on the total annual income, not the individual weekly spike. That's where the real math happens.
