Carlos worked the line at a food processing plant in San Antonio. Steady work, predictable schedule, decent hourly rate. When overtime became available — usually four to six hours on Fridays — his supervisor would post a sign-up sheet on the break room door.
For almost a year, Carlos didn't sign it.
The reason came from a coworker named Pete, who'd been at the plant for eleven years and spoke about money with the confidence of someone who had figured things out. "Overtime's not worth it," Pete told him one afternoon. "The government takes so much more that you barely bring home anything extra. I ran the numbers once. It's basically free work."
Carlos trusted Pete. Pete was older, had a house, seemed like someone who understood how things worked. So Carlos spent his Fridays at home while other people picked up the extra hours.
Then his brother-in-law — an accountant — came to visit for the holidays. Carlos mentioned the overtime thing over dinner. His brother-in-law put down his fork.
"That's not how taxes work," he said.
Here's what Pete got wrong — and what a lot of people get wrong about overtime and taxes. Overtime hours are taxed at your marginal rate, not some special punitive overtime rate. There is no overtime tax. The IRS does not care whether your hours were regular or overtime — it only sees your total income. If you're in the 22% federal bracket, every dollar above that threshold gets taxed at 22% — whether it came from a regular Tuesday or a Friday overtime shift.
| Regular Hours | With 6 OT Hours | |
|---|---|---|
| Gross pay (weekly) | $840 | $1,029 |
| Federal tax (est.) | $118 | $160 |
| FICA (7.65%) | $64 | $79 |
| Net take-home | $658 | $790 |
| Extra take-home from OT | — | +$132/week |
Six overtime hours, after taxes, put $132 more in Carlos's pocket every week. Over 48 weeks of declining the sign-up sheet, that's roughly $6,336 he left behind.
What sometimes confuses people is withholding. When you work overtime, your employer may withhold more federal tax from that paycheck because the payroll system sees a larger-than-usual check and calculates withholding as if you earned that amount every pay period. That can make an overtime paycheck look like it got "taxed more." But it didn't — it just had more withheld. The true-up happens at tax time, when your actual annual income determines what you owe. Any over-withheld amount comes back as a refund.

Carlos ran the numbers with his brother-in-law at the kitchen table that night. He signed up for every available Friday shift starting in January.
Pete still doesn't sign up. Some lessons take longer than others.
The rule is simple: overtime is always worth it financially, because more gross income always means more net income. The tax system is a staircase, not a cliff. You can never take home less by earning more.
