A raise adds income on top of what you already earn, and you can work out how much of it you keep in about ten minutes. The trick is to stop asking “which bracket am I in?” and start asking “what happens to this specific extra slice of money?” Once you split the raise into pieces, the answer is a number you can plan around.
This post gives you a six-step method, two made-up examples with the arithmetic shown, and a prompt that does the math for you.
Why a Raise Never Shrinks Your Paycheck
Federal income tax is built in layers. Each layer of income has its own rate, and a raise only adds income on top of the stack. The part of your income that was already taxed stays taxed at the same rates it was before.
For 2026, Revenue Procedure 2025-32 sets the single-filer brackets this way: 10% on taxable income up to $12,400, 12% up to $50,400, 22% up to $105,700, and 24% up to $201,775. The standard deduction for a single filer is $16,100, and it comes off before any of those rates apply.
So the useful question is how much of a raise you keep, and that depends on three layers of tax: federal income tax, payroll tax, and your state’s tax.
The Six Steps
Here’s the method, in order. You’ll need your salary, your raise, your filing status, and a rough idea of your deductions.
- Find your taxable income now. Take your pay, subtract the standard deduction (or your itemized total), and subtract any pre-tax contributions such as a traditional 401(k).
- Find the top of your current bracket. The IRS table tells you where your current rate ends.
- Split the raise. The part that fits under the top of your current bracket is taxed at the current rate. Anything beyond is taxed at the next rate.
- Add payroll tax. According to IRS Publication 15, Social Security tax is 6.2% of wages up to $184,500 in 2026, and Medicare tax is 1.45% with no wage cap. Together that’s 7.65% on a raise that stays under the Social Security cap.
- Add your state. Use your state’s rate on the raise, or zero if you don’t have a state income tax.
- Subtract it all from the raise. What’s left is your gain.
A Made-Up Example: Alex Gets $5,000
Alex is single, earns $70,000, and gets a $5,000 raise. Alex takes the standard deduction and has no other adjustments. These are invented numbers.
Taxable income before the raise is $70,000 minus $16,100, which is $53,900. After the raise it’s $58,900. Both amounts are above $50,400, so the whole raise lands in the 22% bracket.
| Piece of the raise | Amount |
|---|---|
| Federal income tax (22%) | $1,100 |
| Payroll tax (7.65%) | $382.50 |
| Left over | $3,517.50 |
Check the federal number two ways. Tax on $53,900 is $6,570 ($1,240 plus $4,560 plus $770). Tax on $58,900 is $7,670. The difference is $1,100, which is exactly 22% of $5,000. Alex keeps $3,517.50 of the $5,000, about 70%, or roughly $293 more per month before state tax. If Alex’s state takes 4% of the raise (an assumed rate), that’s another $200, leaving $3,317.50.
That’s a gain you can see before you accept the offer.
A Raise That Crosses a Line
Now the case people worry about. Say taxable income is $48,000 and the raise is $6,000. The 12% bracket ends at $50,400, so only $2,400 of the raise fits under it. The other $3,600 spills into the 22% bracket.
The tax on the raise is $2,400 times 12%, which is $288, plus $3,600 times 22%, which is $792. The total is $1,080. That’s 18% of the raise, a blend of the two rates. The $48,000 you were already earning didn’t get taxed any differently.
That’s the whole mystery of “getting pushed into a higher bracket.” Only the spill-over pays the higher rate, and the spill-over still arrives in your pocket after tax.
Four Ways to Keep More of It
Once you know the number, you can improve it. These are my suggestions.
Send part of the raise to a pre-tax account. The IRS says traditional 401(k) deferrals are not subject to federal income tax until distributed. At a 22% marginal rate, each $100 you route there lowers your federal income tax by $22 for the year. Payroll tax still applies, because the same IRS guide says deferrals are included as wages subject to Social Security and Medicare taxes.
Claim your match first. In my view, if your employer matches contributions, directing enough of the raise to the plan to get the full match comes before anything else, because the match is extra money on top of the tax savings.
Update your withholding. Your employer withholds based on the Form W-4 you submit, and IRS Publication 15 says employees who want to change their federal income tax withholding should submit a new Form W-4. I’d file a new one after a raise.
Compare offers on the same footing. If you’re weighing two job offers, run the six steps on each. A higher salary with a higher state tax can leave you with less than a smaller one without it, and the arithmetic shows it.
Where the Simple Method Can Be Off
The six steps handle the standard case. Two things can make your real number different.
First, some benefits and credits shrink as income rises. For example, the IRS describes the premium tax credit as available between 100% and 400% of the federal poverty line, so crossing the top line ends the credit. When that happens, the extra income is effectively taxed at more than the bracket rate. For what happens when withholding falls short of the tax you owe, see Safe Harbor Rule Underpayment Penalty.
Second, the IRS sets a 22% withholding rate on supplemental wages (37% above $1 million in a year). Where a payment is withheld at that flat rate, the amount withheld can differ from the tax you actually owe on it, and the difference settles when you file.
Let AI Run the Six Steps
Put your own numbers in, or invented ones if you prefer. I’ve included the 2026 federal figures in the prompt so the assistant doesn’t guess.
Calculate my take-home gain from a raise using ONLY these facts.
2026 single-filer brackets (taxable income): 10% to $12,400; 12% to $50,400; 22% to $105,700; 24% to $201,775; 32% to $256,225; 35% to $640,600; 37% above.
2026 standard deduction (single): $16,100.
Payroll tax: Social Security 6.2% up to $184,500 of wages; Medicare 1.45% with no cap.
My details:
- Current salary: [amount]
- Raise amount: [amount]
- Pre-tax deductions (such as traditional 401k): [amount]
- State income tax rate on the raise: [percent, or 0]
Show every step:
1. Taxable income before and after the raise
2. Federal tax before and after, bracket by bracket
3. Federal tax on the raise alone
4. Payroll tax on the raise
5. State tax on the raise
6. Net gain per year and per month
Rules:
- Show all arithmetic.
- Do not assume credits or deductions I did not list.
- If something is missing, ask instead of guessing.
- This is an estimate, not tax advice.
If the numbers look off, compare the assistant’s federal tax to the bracket table yourself. Catching an arithmetic slip takes two minutes.
Check Your First Paycheck After the Raise
The plan on paper is only half the job. The first new paycheck is where you compare it with your estimate.
Open the pay stub and find three lines: gross pay, federal income tax withheld, and the Social Security and Medicare lines. Gross pay should have gone up by your raise divided by the number of pay periods. Payroll tax should have gone up by 7.65% of that increase, if you’re under the Social Security cap. Federal withholding is an estimate based on your W-4, so compare it with your marginal rate times the increase.
If your take-home pay is below your estimate, here is what I’d check: a benefits premium that changed at the same time, a higher 401(k) percentage, or a state tax you hadn’t counted. If it’s above the estimate, check whether withholding is lower than the tax you’ll owe, because the gap shows up when you file.
Write the result next to your estimate, and the next negotiation gets faster.
My Take: Negotiate With the Net in Mind
I’d negotiate using the after-tax number, not the headline. A $5,000 raise sounds like $5,000, but knowing it’s closer to $3,500 in your pocket helps you compare it with the cost of a commute, a move, or a different offer. Knowing your take-home pay after a raise before you answer is, in my view, a real advantage.
Questions People Ask Before a Salary Talk
Can a raise ever reduce my take-home pay? Through the income tax brackets alone, no: each extra dollar is taxed at your bracket rate and you keep the rest. Lines like the 400% poverty-line limit on the premium tax credit work differently, because crossing them ends a benefit, so it’s worth checking whether one applies to you.
Does the 22% apply to my whole salary? No. It applies only to the portion of taxable income in that range. The lower portions are taxed at 10% and 12%.
Do I include the standard deduction? Yes. It reduces taxable income before the bracket rates apply, which is why your overall rate is lower than your bracket rate.
What about overtime? Overtime is part of your pay. The IRS has published Schedule 1-A for the new deductions that include one for overtime, and that deduction has its own rules.
How often should I redo this? My suggestion is whenever your pay changes, and each January when the new brackets and limits come out.
A Ten-Minute Habit
Next time someone mentions a raise, work out the take-home pay after a raise with the six steps. Write down the net amount, the monthly gain, and the date you reviewed your W-4. A number you’ve calculated yourself is a lot more comfortable than one you’ve heard secondhand.
