What we assumed

Effective tax rate here means total tax divided by gross pay, not by taxable income. Dividing by taxable income gives a higher number and is not what most people mean.
The federal bracket shown is the rate on your last dollar of taxable income. It is a rate on part of your income, never on all of it.
The next-$1,000 figure is measured by running the whole calculation again $1,000 higher, so it accounts for state credits and phase-outs rather than assuming a flat bracket. It is an effective marginal rate across that $1,000, not a statutory marginal rate: if the interval crosses the Social Security wage base it averages both sides of it, which is what actually happens to the money.
This estimate uses tax year 2026.
Federal filing status: Single.
Federal income tax uses the IRS standard deduction of $16,100.00. Itemized deductions are not used.
Federal tax credits, capital gains, self-employment tax and AMT are not included. State exemption credits are included where this snapshot carries them.
What a dependent is worth depends entirely on the state, and in several it is worth nothing. The dependents field says so beneath itself when that is the case.
Employer benefits and pre-tax payroll deductions are not included.
This is an estimate, not a tax return or employer withholding notice.
Federal source: IRS Revenue Procedure for tax year 2026.
Texas does not levy a wage income tax in this snapshot. The state tax line is $0.
This state levies no local income tax on wages, so nothing is omitted on that account.

Why your tax rate is lower than your tax bracket

CostAnswer editorialIndependent calculator publisher

Being "in the 22% bracket" does not mean 22% of your pay goes to federal tax. It means the last slice of it does. This page separates the two numbers and shows the gap between them.

What the bracket actually applies to

US federal income tax is charged in bands. The standard deduction comes off first, and what is left is taxed a slice at a time: the lowest band at its rate, the next band at its rate, and so on. Your bracket is the rate on the final slice, never on all of it.

That is why someone on $100,000 sits in the 22% bracket while paying about 13% of their pay in federal income tax. Nothing has been avoided; the lower bands were charged at their own rates and the deduction was not charged at all.

The number that matters for a raise

Neither figure answers "what happens if I earn more". The effective rate is an average of everything already earned, and the federal bracket ignores Social Security, Medicare and state tax.

The rate on your next $1,000 is the one that answers it, and this page measures it by running the whole calculation again a thousand dollars higher. In a state with no wage tax that comes to your bracket plus 7.65%. In a state with its own brackets it is higher, and above the Social Security wage base it drops, because that part of FICA has stopped.

Effective against gross, not against taxable income

There are two ways to write an effective rate and they give different answers. Dividing by taxable income produces a bigger number, because the standard deduction has already been taken out of the denominator.

This page divides by gross pay, which is what people mean when they ask what share of their money goes to tax. If you compare against a figure published elsewhere, check which denominator it used before concluding one of them is wrong.

Questions about this calculator

Why is my effective tax rate so much lower than my bracket?

Because the bracket only applies to your top slice of income. The standard deduction is taxed at nothing, and every band below your bracket is charged at its own lower rate.

The gap widens as income rises through a band and narrows as you approach the next one.

Does a raise push all of my income into a higher bracket?

No. Only the part above the threshold is taxed at the higher rate. Crossing into a new bracket never reduces your take-home pay.

The next-$1,000 figure on this page is what the extra money is actually taxed at, including FICA and state tax.

Why does the next-$1,000 rate fall at high incomes?

Social Security stops at the yearly wage base, so once your pay is past it that 6.2% is no longer charged on additional earnings. Medicare continues, and an extra 0.9% starts once you pass its threshold.

Is this what I will owe on my return?

No. This is wage income under the published schedules. Credits, itemised deductions, retirement contributions and any income that is not salary all change the answer, and none of them are modeled here.

Terms used here

Effective tax rate: Total tax divided by gross pay. An average across everything you earned.
Marginal rate: The rate charged on the next dollar you earn. Higher than the effective rate whenever the brackets are progressive.
Tax bracket: A band of taxable income and the rate charged on the part of your income inside it.
Taxable income: Gross pay less the standard or itemised deduction. What the brackets are applied to.

Practical tips

Compare two states on the same salary to see how much of the difference is state tax rather than pay.

If you are deciding whether extra work is worth it, the next-$1,000 rate is the number to use, not the effective rate.

A traditional 401(k) contribution reduces taxable income, so it comes off at your bracket rate rather than your effective rate.

Limits and caveats

Wage income only. This is not a tax return and not tax advice.

Local income taxes are named where a state has them but never estimated, so real take-home in those places is lower.

Where a state has not published its current schedule, the page uses the latest one it did publish and says which year that is.

Engine notes

Rounding, versioning, and omissions that sit beside the guide rather than repeating it.

Effective rate is measured against gross pay. Total tax divided by gross pay, not by taxable income. Dividing by taxable income gives a higher number (the $16,100 standard deduction has already come out of it), and it is not what people mean when they ask what share of their pay goes to tax.
The bracket is a rate on your last dollar. Your federal bracket is read from the rate schedule for your filing status, using taxable income. It applies to the slice of income inside that band and nothing below it, which is the whole reason the effective rate comes out lower. The gap between the two is stated on the page rather than left to be noticed.
The next $1,000 is measured, not assumed. The rate on additional pay is found by running the entire calculation again a thousand dollars higher and taking the difference. That is slower than reading a bracket off a table, and it is the most reliable general method over a combined federal, payroll, and state engine; states that phase a credit out, subtract federal tax, or switch schedules have no single published marginal rate to read. It is an effective marginal rate across that $1,000, not an instantaneous one: where the interval crosses a boundary such as the Social Security wage base, the figure is the weighted average of both sides. That is the right answer to what happens to your next $1,000, and it is deliberately not labelled a statutory marginal rate.
What is left out. Credits, itemized deductions, retirement contributions, self-employment tax and income other than wages are not modeled. Local income taxes are named where a state has them but never estimated. Where a state schedule in this snapshot is a year behind, the page says so.
