How Tax Brackets Actually Work

The most expensive misunderstanding in personal finance is believing a raise can leave you worse off. It cannot. Here is what really happens when you cross a bracket line, with the 2026 numbers.

The 2026 federal brackets

These are marginal rates. Each one applies only to income that falls inside its band.

RateSingle (taxable income)Married filing jointly
10%$0 – $12,400$0 – $24,800
12%$12,400 – $50,400$24,800 – $100,800
22%$50,400 – $105,700$100,800 – $211,400
24%$105,700 – $201,775$211,400 – $403,550
32%$201,775 – $256,225$403,550 – $512,450
35%$256,225 – $640,600$512,450 – $768,700
37%$640,600 +$768,700 +

Before any of this applies, subtract the standard deduction: $16,100 single, $32,200 married filing jointly, $24,150 head of household.

A worked example: $80,000, single

Gross income $80,000, minus the $16,100 standard deduction, leaves $63,900 of taxable income. That income is sliced across three brackets:

How $63,900 of taxable income is taxed
10%$1,240
12%$4,560
22%$2,970
Total federal tax$8,770

First band$12,40010%$1,240
Second band$38,00012%$4,560
Third band$13,50022%$2,970
Total$63,900—$8,770

The marginal rate is 22%. The effective rate on gross income is 10.96%. Those two numbers describe the same tax bill and differ by more than half.

The raise myth, in dollars

Suppose a raise pushes your taxable income from $50,400 to $50,500 — straight across the 12%-to-22% line. How much extra federal tax do you owe?

$22.00. Only the $100 above the threshold is taxed at 22%. You keep $78 of the raise. There is no version of the US bracket system in which earning more leaves you with less.

Why your effective rate keeps falling behind

Every filer walks up the same ladder from the bottom. A $250,000 earner still pays 10% on their first $12,400 of taxable income, exactly like everyone else. That is why effective rates trail marginal rates at every income level:

Gross (single)TaxableFederal taxMarginalEffective
$52,000$35,900$4,06012%7.81%
$80,000$63,900$8,77022%10.96%
$120,000$103,900$17,57022%14.64%

What actually lowers your bill

This covers federal income tax only. Social Security and Medicare are separate flat payroll taxes that apply from your first dollar — see how they hit your paycheck — and most states add their own income tax on top.

FAQ

Can a raise put me in a higher bracket and lower my take-home pay?
No. Only the dollars above the bracket threshold are taxed at the higher rate. Crossing from the 12% into the 22% bracket by $100 costs $22 on that $100 — the rest of your income keeps its original rates. Your take-home always rises.
What is the difference between marginal and effective tax rate?
Your marginal rate is the rate on your next dollar earned. Your effective rate is total tax divided by total income. A single filer earning $80,000 has a 22% marginal rate but pays about 10.96% of gross income in federal tax — less than half.
What is the 2026 standard deduction?
$16,100 for single filers, $32,200 for married filing jointly, and $24,150 for head of household. It is subtracted from your income before brackets apply, which is why the first chunk of your earnings is effectively taxed at 0%.
Do tax brackets apply to gross income?
No — they apply to taxable income, which is gross income minus the standard or itemized deduction and any pre-tax contributions such as 401(k) or HSA. This is why two people with identical salaries can owe very different amounts.
Should I avoid earning more to stay in a lower bracket?
Never, for income tax purposes. Extra income always leaves you with more after tax. The rare exceptions involve benefit cliffs — subsidies or credits that phase out abruptly — not the brackets themselves.
