Someone turns down a promotion because the raise would push them into a higher tax bracket and they would take home less.
This is the most durable false belief in personal finance, and it is worth being precise about why it is false: it is not that this rarely happens. It cannot happen. Not through tax brackets, in any bracket, at any income, under any filing status.
The reason is structural. A bracket taxes only the income that falls inside it, and no bracket rate is anywhere near 100%. So an additional dollar of income produces, at absolute worst, 37 cents of additional federal tax. You keep 63 cents. You cannot end up behind.
What follows is the arithmetic that shows this, the two numbers people are conflating when they believe otherwise, and — importantly — the genuinely real phenomenon that the myth has borrowed its plausibility from.
A note before you start. This is general education, not tax advice. Federal figures are tax year 2026, from IRS Revenue Procedure 2025-32 and the Social Security Administration; every dollar figure is computed by this site's own tax engine on a single filer taking the standard deduction with no dependents or pre-tax deferrals unless stated. State figures come from this site's sourced 50-state dataset. Benefit cliffs, discussed in section 5, are programme-specific and are not modelled by any calculator on this site.
1. The two rates, and which one people mean
Almost every conversation about "my tax rate" involves two different numbers used interchangeably.
Your marginal rate is the rate on your next dollar. It is what "being in the 22% bracket" describes.
Your effective rate is your total tax divided by your total income. It is the average across every dollar you earned.
For a single filer on $85,000 in 2026:
| Marginal federal rate | 22% |
| Effective federal rate | 11.61% |
Both are correct. They answer different questions. The marginal rate tells you what happens if you earn more; the effective rate tells you what you actually paid.
When someone says "I'm in the 22% bracket so I pay 22% of my income in tax," they have taken a marginal number and used it as an effective one. That single substitution generates the myth, and once you separate the two the myth has nowhere to live.
2. The arithmetic, slice by slice
Here is where the $9,870 comes from.
A single filer earning $85,000 first subtracts the 2026 standard deduction of $16,100, leaving $68,900 of taxable income. That amount is then cut into slices, each taxed at its own rate:
| Slice of taxable income | Rate | Tax on that slice |
|---|---|---|
| The first $12,400 | 10% | $1,240.00 |
| From $12,400 to $50,400 — $38,000 | 12% | $4,560.00 |
| From $50,400 to $68,900 — $18,500 | 22% | $4,070.00 |
| Total | $9,870.00 |
Notice what the 22% applies to: $18,500, not $68,900 and certainly not $85,000. It is the last slice only.
$9,870 divided by $85,000 gives the effective rate of 11.61%.
Now give them a raise
Suppose they get a $5,000 raise to $90,000. Taxable income becomes $73,900, still inside the 22% bracket:
- Additional taxable income: $5,000
- Additional federal income tax: $5,000 × 22% = $1,100
- Additional FICA: $5,000 × 7.65% = $382.50
- They keep $3,517.50 of the $5,000.
Less than the whole raise, obviously. But more than zero, which is the only thing the myth requires to be wrong.
And now push them across a bracket line
Suppose instead the raise takes taxable income from $68,900 to $110,000 — through the 24% threshold at $105,700.
The first $105,700 is taxed exactly as it was before. Nothing about crossing the line reaches backwards. Only the $4,300 above $105,700 is taxed at 24%.
This is the crux. There is no mechanism by which entering a bracket changes the treatment of income below it. The brackets are not a lookup table where your income selects a single rate — they are a set of slices, and you fill them from the bottom.
See your own marginal and effective rates side by side3. Why the effective rate is always lower
For anyone with income spanning more than one bracket, the effective rate is necessarily below the marginal rate, because the average of a set of numbers is always below its maximum unless every number is the maximum.
This holds at every income:
| Taxable income | Marginal rate | Roughly what the effective federal rate looks like |
|---|---|---|
| $12,000 | 10% | ~10% — one bracket, so they nearly match |
| $68,900 | 22% | ~14.3% of taxable income |
| $200,000 | 32% | well under 25% |
| $700,000 | 37% | well under 32% |
The gap widens as you climb, because more of your income sits in lower brackets beneath you. A top-rate taxpayer is paying 37% on their last dollar and something substantially lower on average — which is why "the top rate is 37%" tells you very little about anyone's actual bill.
This is what "progressive" means
The gap between marginal and effective is not a loophole, an accounting trick, or evidence that the wealthy avoid tax. It is the mechanical result of taxing slices at rising rates, and it applies identically to everyone. A person earning $85,000 and a person earning $850,000 both pay 10% on their first $12,400 of taxable income.
4. The same thing happens at state level
State income taxes work the same way, with one useful simplification.
Twelve states charge a single flat rate — Arizona, Colorado, Georgia, Illinois, Indiana, Iowa, Kentucky, Louisiana, Michigan, North Carolina, Pennsylvania and Utah. With one bracket there is essentially no gap between marginal and effective. Pennsylvania is the purest case: 3.07% on essentially all compensation with no standard deduction, so an $85,000 earner pays exactly $2,610, and their marginal and effective state rates are both 3.07%.
Twenty-nine states run graduated brackets, from Hawaii's twelve down to two, and the marginal-versus-effective gap appears there exactly as it does federally.
Nine states charge nothing, so both rates are zero.
One consequence worth noting: your combined marginal rate — federal plus state plus FICA — is what actually determines the value of a pre-tax deferral or an extra hour of work. On $85,000 in Ohio that is 22% federal, plus Ohio's marginal rate, plus 7.65% FICA. It is a considerably larger number than the federal bracket alone, and it is the one to use when deciding whether an additional dollar is worth earning.
5. The real thing the myth is borrowing from
Persistent myths usually have a grain of truth somewhere, and this one does. It is just not tax brackets.
Benefit cliffs are real. Some income-tested programmes end abruptly at a stated income rather than phasing out gradually. Cross the threshold by a dollar and the entire benefit stops. In that situation a small raise genuinely can leave a household worse off — sometimes substantially.
The distinction matters because the two things behave completely differently:
| Tax brackets | Benefit cliffs | |
|---|---|---|
| What crossing costs | A higher rate on the income above the line only | Potentially the entire benefit |
| Can it leave you worse off? | No, ever | Yes |
| Is it worth planning around? | No — there is nothing to plan | Yes, carefully |
Someone who watched a family member lose assistance after a raise has seen something real. They have simply attributed it to the wrong mechanism, and the wrong mechanism is the famous one.
If you are near an income-tested threshold — for healthcare subsidies, childcare assistance, housing support, or similar — that is a genuine reason to model a raise carefully. It is not a reason to believe brackets work that way, and the remedies are completely different: a cliff can sometimes be managed with pre-tax deferrals that reduce countable income, whereas a bracket needs no management at all.
6. Three related confusions worth clearing up
Withholding is not tax
A bonus arriving with roughly a third missing does not mean bonuses are taxed punitively. Supplemental wages are commonly withheld at a flat 22% federal rate, which is a prepayment. At filing, the bonus is added to ordinary income and taxed at your real rates; excess withholding comes back as refund.
If your marginal rate is 12%, flat-22% withholding overpays and the Treasury holds your money until you file. The tax on a bonus is identical to the tax on salary.
The standard deduction is not a bracket
A common muddle: "I earn $85,000 so I'm taxed on $85,000." You are taxed on $68,900 — income after the standard deduction. The brackets apply to taxable income, not to salary, and the gap is $16,100 for a single filer in 2026.
This is also why the effective rate calculated against gross salary (11.61%) is lower than the same tax measured against taxable income (14.3%). Both are used; it is worth knowing which is being quoted.
FICA is flat, and it is not a bracket at all
Social Security at 6.2% and Medicare at 1.45% are charged on gross pay, unaffected by the standard deduction or by brackets. Social Security stops at the wage base ($184,500 in 2026); Medicare never stops.
This produces the one situation that genuinely resembles the myth in reverse: earn past the Social Security wage base and your paycheck gets larger mid-year with no raise at all. It is the closest thing to a bracket discontinuity in the whole system, and it moves in the taxpayer's favour.
7. Where the marginal rate genuinely matters
Having established that the marginal rate does not do the damage people fear, it is worth saying what it is good for — because it is the right tool for several real decisions.
Valuing a pre-tax deferral. A dollar into a traditional 401(k) saves you your marginal rate, not your effective rate. For our $85,000 single filer in Ohio that is 22% federal plus Ohio's marginal rate — so roughly a quarter of every deferred dollar is tax you do not pay this year. Using the 11.61% effective rate would understate the benefit by more than half.
Valuing a deduction. Same logic. A $1,000 deductible expense is worth $220 federally at a 22% marginal rate, not $116 at the effective rate. Deductions are always worth your marginal rate.
Deciding whether extra work is worth it. Overtime, a side project, a second job — the relevant figure is your combined marginal rate: federal bracket, plus state marginal rate, plus 7.65% FICA, plus any local income tax. At $85,000 in Ohio that combination is meaningfully above 30%, which is a legitimate input into whether an extra shift is worth taking. It is not a reason to refuse it — you still keep the majority — but it is the honest number.
Comparing traditional against Roth contributions. The comparison turns on your marginal rate now against your expected marginal rate in retirement. Effective rates are the wrong tool for this entirely.
Notice what all four have in common: they are questions about the next dollar, which is exactly what a marginal rate describes. The myth arises from using it for a question about all your dollars, which is what the effective rate is for.
8. Three more numbers people quote as "my tax rate"
Beyond marginal and effective, several other figures circulate, and they are all different.
Your withholding rate. What your employer actually takes, driven by your W-4 rather than by the brackets. If you get a large refund every year your withholding rate exceeds your real tax rate; if you owe every April it is below it. A refund is not a bonus — it is the return of an interest-free loan you made to the Treasury.
Your effective rate on taxable income versus on gross. These differ by the standard deduction. Our $85,000 earner pays 11.61% measured against gross salary and about 14.3% measured against the $68,900 of taxable income. Both get quoted, and the smaller one is more common in consumer writing while the larger is more common in policy writing.
Your all-in rate. Federal income tax plus FICA plus state — 21.17% for our Ohio example. This is arguably the most honest "what do I actually lose" figure, and it is almost never the one people mean when they name a bracket.
The practical upshot: when someone tells you their tax rate, they could mean any of five things. It is worth asking which.
9. Why the myth survives despite being easy to disprove
The arithmetic here fits on one screen and anyone can check it. It is worth asking why the belief persists, because the answer changes how to correct it.
The word "bracket" implies a container. Everyday usage — an age bracket, a weight bracket — describes a category you fall entirely inside. Tax brackets do not work that way, and the vocabulary actively suggests they do. Nothing in the name hints at slices.
Nobody watches the arithmetic happen. Withholding is invisible and the annual return is prepared by software or an accountant. Most people never see their own tax computed slice by slice, so the correct model has no opportunity to form.
It has an adjacent true version. Benefit cliffs are real and do exactly what the myth describes. Someone who watched a relative lose assistance after a raise has seen the effect; they have attached it to the famous mechanism rather than the actual one.
Withholding on bonuses appears to confirm it. A bonus arriving with a third missing looks exactly like punitive taxation of extra income. That it is a prepayment, reconciled at filing, is not visible in the moment.
The practical consequence: correcting it works better with the slice table than with the assertion. "A raise cannot cost you money" is a claim people have heard and disbelieved. Showing that the 22% applies to $18,500 rather than $68,900 is something they can check for themselves.
10. Where to see your own numbers
Two places, and they will not agree, which is itself informative.
Your pay stub shows withholding, not tax. It reflects your W-4 elections rather than your actual liability, and the gap between them is what produces a refund or a bill.
Your tax return shows the real figures. Your total tax divided by your total income is your effective rate; the rate applying to your last dollar of taxable income is your marginal rate. Both are derivable from the return, and neither is printed on it as a headline.
If your refund is large every year, your withholding rate exceeds your tax rate and you have been lending money to the Treasury at zero interest. Adjusting the W-4 moves that money into your paychecks. If you owe every April, the reverse — and a large enough shortfall can attract an underpayment penalty, which is worth avoiding by adjusting withholding rather than saving up for it.
Frequently asked questions
Can a raise ever reduce my take-home pay? Not through tax brackets — a bracket applies only to income above its threshold and no rate approaches 100%, so an extra dollar always leaves you with more. Income-tested benefit cliffs are a separate mechanism that genuinely can, and they are worth modelling if you are near one.
What is the difference between marginal and effective rate? Marginal is the rate on your next dollar; effective is your total tax divided by your total income. At $85,000 a single filer has a 22% marginal federal rate and an 11.61% effective one. Both are correct, and confusing them is what creates the bracket myth.
Why is my effective rate always lower than my bracket? Because your income fills the lower brackets first and each is taxed at its own lower rate. The average of a rising set of rates is always below its top value. That is what graduated taxation means.
Does crossing into a higher bracket retax my earlier income? No. Income below the threshold is taxed exactly as it was before. Only the portion above the line is taxed at the higher rate.
Why did my bonus get taxed at 22% when my bracket is 12%? It was withheld at 22% under the flat supplemental-wage method, not taxed at it. At filing the bonus is treated as ordinary income and the over-withholding comes back as refund. The money is early, not lost.
What is my real marginal rate? Federal bracket plus state marginal rate plus 7.65% FICA, and plus any local income tax. That combined figure is what determines the value of an extra hour's work or a pre-tax deferral, and it is meaningfully higher than the federal bracket alone.
Do flat-tax states avoid this confusion? Largely. In the twelve flat states there is one rate, so marginal and effective are essentially the same at state level. The federal graduated brackets still apply on top, so the confusion can still arrive from that direction.
