The U.S. federal income tax system is progressive, meaning you pay higher rates on higher portions of income. But it works in layers, not as an all-or-nothing switch. Moving into a higher bracket doesn’t mean the government suddenly taxes all of your income at that higher rate. It only means you pay the higher rate on the additional income that falls within that higher bracket. You keep paying the lower rates on everything below it, the same as before.

This single misunderstanding causes a lot of unnecessary anxiety around raises and bonuses. Nobody actually takes home less money overall by earning more. You only ever pay each bracket’s rate on the income within that specific bracket.

For 2026, single filers face rates of 10% on income up to $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. Married couples filing jointly have wider brackets at each level, roughly double the single-filer thresholds at the lower rates, with the top 37% rate beginning above $768,700.

The IRS adjusts these thresholds annually for inflation. That’s why the exact dollar cutoffs shift slightly from year to year, even when the percentage rates themselves stay the same. The 2026 brackets specifically reflect this year’s inflation adjustment. They apply to income you earn throughout the calendar year, and report on the return you file the following spring.

Consider a single filer earning $70,000 in taxable income in 2026. They pay 10% on the first $12,400, 12% on the next portion up to $50,400, and 22% on the remaining income from $50,400 to $70,000. Adding those layers together produces a total tax bill of about $10,112, an effective tax rate of roughly 14.5%, even though this person sits in the 22% marginal bracket.

That gap (a 22% marginal bracket producing a 14.5% effective rate) is the whole point of understanding brackets correctly. The marginal rate tells you the rate on your next dollar of income. The effective rate tells you what you actually paid as a percentage of your total income. The two are almost never the same number.

Your marginal tax rate is the rate that applies to your last, highest dollar of income: the bracket you’re technically “in.” Your effective tax rate is what you get by dividing your total tax bill by your total income: a blended average across every bracket your income passed through. The marginal rate is the more useful number for decisions about additional income, like whether a raise or extra freelance work is worth taking, since it tells you what rate applies to that specific additional income. The effective rate is the more useful number for understanding your overall tax burden.

The effective rate is always lower than the marginal rate under a progressive system with more than one bracket, since it blends in the lower rates that apply to earlier portions of income. Comparing your effective rate year over year is a more accurate way to track how your overall tax burden is changing than comparing marginal brackets alone, which only tell part of the story.

A common fear is that accepting a raise that pushes income into a new bracket will result in a net pay cut. The worry usually sounds like this: “the government taxes the whole raise at the new rate.” That’s never actually true under a progressive bracket system. Only the portion of income that falls within the new, higher bracket faces that higher rate. Every dollar you earn below that threshold keeps facing the same rate as before. A raise might mean the government taxes your extra income at a higher marginal rate than your previous earnings, but it never results in less total after-tax income than before the raise.

Employers sometimes withhold bonuses at a flat rate that can look higher than expected on the paycheck itself. That fuels the same misconception. The withholding rate is not the same as your actual tax liability on the bonus. The IRS reconciles and refunds any over-withholding when you file your annual tax return, the same way it does for regular paycheck withholding.

This misunderstanding is common enough that it has a name, “bracket creep anxiety,” and it occasionally leads people to turn down raises or extra work out of a mistaken belief that it isn’t worth it. Understanding that only the marginal slice faces the higher rate removes that concern entirely. More gross income always means more net income under a progressive system, never less.

Brackets apply to taxable income, not your gross salary. Pre-tax deductions like traditional 401(k) contributions, along with the standard deduction or itemized deductions, reduce your taxable income before the IRS ever applies brackets to it. This is part of why a pre-tax retirement contribution offers a real, immediate tax benefit. It can reduce the portion of your income that faces your highest marginal rate first, since brackets fill from the bottom up.

For 2026, the standard deduction is $16,100 for single filers and $32,200 for married couples filing jointly. That much income escapes federal income tax entirely, before any bracket calculation even begins, regardless of how you spend or save it afterward.

The exact effective tax rate for your income depends on your filing status, deductions, and total taxable income. Our Take-Home Pay Calculator estimates your net paycheck after typical federal, state, and payroll tax withholding, giving you a realistic number based on how brackets actually apply.
