Salary vs. hourly taxes work the same way at the federal and state level: the IRS and state tax agencies apply identical rates to both, because a dollar of wages is a dollar of wages regardless of how it was earned. What differs is how much your employer withholds from each paycheck along the way. Salaried checks are steady, so withholding tracks your real tax bill closely. Hourly checks fluctuate, and the payroll formula reacts to each check as if that pace will hold all year, which can make the tax bite look uneven even though the underlying rate never changed.
The Rates Are Identical
The IRS does not have a separate schedule for hourly workers. Both salary and hourly earnings show up as “wages” on your W-2 and flow through the same brackets on your return. For 2026, a single filer’s taxable income is taxed at 10% on the first $12,400, 12% up to $50,400, 22% up to $105,700, 24% up to $201,775, 32% up to $256,225, 35% up to $640,600, and 37% above that.1Internal Revenue Service. Rev. Proc. 2025-32 A single filer with $80,000 in taxable income lands in the 22% bracket whether that came from a fixed salary, hourly shifts, or a mix.
FICA works the same way. Every employee pays 6.2% toward Social Security on wages up to the $184,500 wage base for 2026, and 1.45% for Medicare with no ceiling.2Internal Revenue Service. Topic No. 751, Social Security and Medicare Withholding Rates Wages above $200,000 in a calendar year ($250,000 for married filing jointly) trigger an additional 0.9% Medicare tax on the excess.3Social Security Administration. FICA and SECA Tax Rates Employers withhold these amounts identically for salaried and hourly workers.
States that impose an income tax follow the same principle. Your annual earnings and filing status drive the bill, not your pay schedule. What you owe at year-end depends on how much you made, not how you made it.
Why Hourly Paychecks Look Taxed Differently
If the rates match, why does an hourly coworker’s stub sometimes show a much heavier tax bite than yours on a similar-sized check? It comes down to how payroll software calculates withholding.
Employers use the IRS percentage method in Publication 15-T. The software takes your taxable wages for the current pay period, multiplies by the number of pay periods in a year, applies the annual brackets to that projection, then divides the result back down to the current check.4Internal Revenue Service. Publication 15-T, Federal Income Tax Withholding Methods Every paycheck is treated as if you’ll earn that same amount every period for the entire year.
For a salaried employee earning $60,000 on a semi-monthly schedule, each check is $2,500. The projection ($2,500 × 24) equals the actual salary of $60,000, so withholding lines up with the real tax liability.
Hourly math gets bumpier. Say you normally work 40 hours a week at $25 per hour, or $1,000 gross. The system projects $52,000 for the year and withholds against that. The next week you pick up 20 hours of overtime and gross $1,750. The system now projects $91,000 for the year and pulls withholding based on that higher bracket, even though your actual annual pace hasn’t moved. Slow weeks work in reverse: a short check gets under-withheld because the software assumes you’ll stay slow.
The Overtime Tax Myth
This is where the persistent belief that overtime is “taxed more” comes from. It isn’t. Overtime wages hit the same brackets as regular wages. What changes is the withholding on the bigger check, because the payroll system briefly assumes the higher pace will last all year. The extra amount pulled is the system overshooting, and you generally get it back as a refund when you file.
If you earn $55,000 in regular wages and $8,000 in overtime, your income is $63,000. The IRS taxes that $63,000 the same way it taxes $63,000 earned entirely from a salary. There is no separate overtime bracket and no penalty for earning some income at time-and-a-half. Only the timing of withholding shifts.
Where Pay Structure Does Affect Your Total Tax
Pay structure doesn’t change tax rates, but it does interact with overtime eligibility, which can change how much income you earn in the first place. Under the Fair Labor Standards Act, employees are either exempt (no overtime pay) or non-exempt (entitled to 1.5 times the regular rate beyond 40 hours per week).
The federal salary threshold for the executive, administrative, and professional exemptions is $684 per week, or $35,568 annually. Employees below that line must be treated as non-exempt regardless of duties.5U.S. Department of Labor. Earnings Thresholds for the Executive, Administrative, and Professional Exemptions
A non-exempt hourly worker who puts in 50 hours gets paid for 50, with 10 at time-and-a-half. An exempt salaried worker at 50 hours earns the same flat salary. More gross income means more taxable income for the hourly worker when overtime is available. That is an income difference, not a rate difference, but it matters when you’re planning your withholding.
Keeping Withholding Accurate When Hours Vary
Salaried employees can often set the W-4 once and leave it. Hourly workers with fluctuating schedules usually can’t, at least not if they want to avoid a surprise at filing time.
Step 4(c) of the W-4 is labeled “Extra withholding.” It lets you request a flat dollar amount pulled from every paycheck on top of the formula-based figure.6Internal Revenue Service. Form W-4, Employee’s Withholding Certificate If you tend to owe at filing, adding $20 or $50 per check here can smooth the year out. The IRS Tax Withholding Estimator can help you set the number based on year-to-date earnings and expected income.7Internal Revenue Service. Tax Withholding
Publication 15-T also describes a “cumulative wages method” that averages earnings across all pay periods so far in the year instead of annualizing each check on its own. It produces much more accurate withholding for variable-hour workers, but you have to request it in writing and your employer has to agree.4Internal Revenue Service. Publication 15-T, Federal Income Tax Withholding Methods Most large payroll systems support it; not every employer will use it.
Revisit your W-4 midyear if your hours shift meaningfully. A second job, lost overtime, or a move to part-time all change how well your withholding tracks reality.
Avoiding an Underpayment Penalty
If withholding falls short and you owe more than $1,000 at filing, the IRS may add an underpayment penalty, which is essentially interest on what should have been paid throughout the year.8Office of the Law Revision Counsel. 26 USC 6654 – Failure by Individual to Pay Estimated Income Tax You avoid it by meeting any one of these safe harbors:
- You owe less than $1,000 after withholding and refundable credits.
- Your withholding and estimated payments covered at least 90% of this year’s tax.
- Your withholding covered at least 100% of last year’s total tax liability (110% if last year’s adjusted gross income was over $150,000, or $75,000 if married filing separately).
The prior-year safe harbor is the easiest target for hourly workers because it’s a fixed, knowable number. Pull last year’s tax liability from your return, divide by the number of paychecks you expect this year, and make sure at least that much is being withheld per period. If your hours drop and withholding falls behind, raise the amount in Step 4(c) or send a quarterly estimated payment directly to the IRS to close the gap.9Internal Revenue Service.

Whatever happened with withholding during the year gets reconciled on Form 1040. Two people with the same filing status, income, and deductions owe the same tax, whether one earned it on salary and the other on the clock.10Internal Revenue Service.
