Will a raise push me into a higher bracket and cost me money?
Brackets tax layers of income, not all of it. A worked example of what a raise really costs, plus the two places where extra income genuinely does bite.
Quick answers
- Can earning more leave me with less take-home pay?
- Not from the rate brackets. A higher rate applies only to the income above the line, so more pay always means more after tax. Losing a credit is a separate question, and that one can bite.
- What is the difference between my bracket and my tax rate?
- Your bracket is the rate on your last dollar of income. Your effective rate is the total tax divided by total income, and it is always lower because the earlier layers were taxed less.
- Should I turn down overtime to stay in a lower bracket?
- No. Extra hours are taxed at your top rate only on the extra pay, and you keep the rest. The only reason to weigh it is a credit or subsidy that phases out at your income level.
A higher bracket applies only to the income above the line, so a raise never leaves you with less take-home pay. The places where more income genuinely costs you are credits and subsidies that phase out, not the rate tables.

Brackets are layers
Income tax is charged in layers. For a single filer the first layer of taxable income is taxed at ten percent up to $11,925, the next layer at twelve percent up to $48,475, the next at twenty-two percent up to $103,350, and so on up the table.
Crossing a line moves only the layer above it. The IRS puts it the same way: when income reaches a higher bracket, the higher rate applies to the part of the income inside that bracket, not to the whole of it. Nothing that was taxed at twelve percent yesterday is taxed at twenty-two percent today because you earned more.
A worked example
Take a single filer whose taxable income, after the standard deduction of $15,750, sits exactly at the top of the twelve percent band, $48,475. Every dollar earned up to that point has already been taxed at ten or twelve percent, and a raise does not disturb any of it.
Now add the raise. The first dollar above the line is taxed at twenty-two percent, so it leaves seventy-eight cents in your pocket instead of the eighty-eight cents a dollar below the line leaves. That is the whole of the effect. The band above is wide, running all the way to $103,350, so a raise would have to be many times the size of a normal one before any of it met the next rate.
You keep less of each new dollar than you kept of the old ones, and you still keep most of it.
Marginal rate versus effective rate
Your marginal rate is the rate on your last dollar. It is the number people mean when they say what bracket they are in, and it is the right number for deciding whether extra work is worth it.
Your effective rate is the total tax divided by total income. It is always the lower of the two, because the standard deduction came off before any tax was charged and the earlier layers were taxed at ten and twelve percent. Someone in the twenty-two percent bracket usually pays an effective rate well under that.
Where extra income really does bite: credit phase-outs
Credits are where more income can genuinely cost you something. The child tax credit begins to fade once income passes $200,000, or $400,000 for a couple filing jointly, and it comes down gradually rather than stopping at once. The child tax credit covers how far it falls.
The education credits do the same across a narrower range. For a single filer they shrink from $80,000 and are gone by $90,000, which makes that band the one place a modest raise can cost real money in a year with tuition. Education credits has the detail.
Even here the raise is worth taking. You lose part of a credit, not the whole of the extra pay.
Where extra income really does bite: the marketplace cliff
The genuine cliff is health coverage bought through the marketplace. For a year after 2025, household income above four hundred percent of the federal poverty line ends eligibility for the premium tax credit outright, and there is no cap on repaying what was already advanced to your insurer during the year.
That is a real edge rather than a slope: crossing it can turn a year of subsidized premiums into a balance due on the return. If you buy coverage that way and a raise puts you near the line, report the change to the marketplace during the year rather than discovering it in April, and read Form 1095-A before you file.
Other edges worth knowing
The deductions for qualified tips and overtime start to phase out above $150,000 for a single filer. The extra deduction for seniors phases out above $75,000. And long-term capital gains and qualified dividends are taxed at nothing at all until taxable income reaches $48,350, above which the rate steps to fifteen percent.
What to do with a raise
Check your withholding after it lands rather than before. Payroll adjusts the tables to the new salary automatically, but anything you set by hand on a Form W-4, and any second job or freelance income, is still sized for the old number. A withholding checkup for 2026 is the short version, and Form W-4 is where the change is made.
The short answer
At the federal level, rate brackets alone never leave you with less take-home pay after a raise. Weigh a credit or a subsidy that phases out at your income; do not turn down money over the rate tables.
