Earned Income Tax: Brackets, Credits, and Payroll Rules

Earned income tax is the combination of levies that apply to money you make from working: federal payroll taxes of 7.65% on wages (15.3% if you’re self-employed), a progressive federal income tax with brackets from 10% to 37% in 2026, and in some places a local flat tax of roughly 1% to 3%. Lower-income workers can claw back a meaningful share of that through the Earned Income Tax Credit, worth up to $8,231 in 2026 for a family with three or more qualifying children.

What Counts as Earned Income

Earned income is money you receive for work you personally perform. That covers gross wages and salaries from an employer, tips, and sales commissions. It also covers self-employment income: freelancing, gig work, independent contracting, and running a small business all generate earned income when you provide goods or services for pay.¹

Several kinds of money you receive don’t count. Interest, dividends, and capital gains are taxable but sit in the “unearned” category with different rules. Retirement distributions from pensions, 401(k) plans, and IRAs are excluded even though the underlying dollars started as wages.¹ Child support, inheritances, and gifts are not earned income. Social Security benefits aren’t either, though a portion may still be subject to regular income tax at higher incomes.

The distinction matters for two reasons. Unearned income isn’t subject to payroll taxes, and it doesn’t count when the IRS calculates your Earned Income Tax Credit eligibility.

Federal Payroll Taxes

Before your paycheck hits your account, your employer withholds taxes under the Federal Insurance Contributions Act. As an employee, you pay 6.2% of wages toward Social Security and 1.45% toward Medicare.² Your employer matches both, so 15.3% of your wages goes into the system in total.

The Social Security portion stops at a ceiling. For 2026, only the first $184,500 of wages is subject to the 6.2% tax.³ Every dollar above that is exempt from Social Security withholding. Medicare has no cap; the 1.45% applies to all wages.

An extra charge lands on high earners. Wages above $200,000 for a single filer, or $250,000 for a married couple filing jointly, trigger an Additional Medicare Tax of 0.9% on the excess.⁴ Your employer does not match this portion. It comes entirely from your pay.

If You’re Self-Employed

With no employer to cover half, you pay the full 15.3% yourself: 12.4% for Social Security and 2.9% for Medicare.⁵ The same $184,500 Social Security wage base applies, and the 0.9% Additional Medicare Tax hits self-employment earnings above $200,000 for single filers.⁴

There is one break. You can deduct the employer-equivalent half (7.65%) when calculating your adjusted gross income, which lowers your income tax bill even though it doesn’t reduce the self-employment tax itself.⁵ You must file Schedule SE with your return once your net self-employment earnings reach $400.⁶

Federal Income Tax Brackets for 2026

On top of payroll taxes, your earned income runs through the federal income tax system. The brackets are progressive, meaning each rate applies only to income within its range, not to your entire earnings. For 2026, single filers face these brackets:⁷

10% on income up to $12,400
12% on $12,401 to $50,400
22% on $50,401 to $105,700
24% on $105,701 to $201,775
32% on $201,776 to $256,225
35% on $256,226 to $640,600
37% on income over $640,600

Married couples filing jointly get roughly doubled thresholds. Their 10% bracket covers income up to $24,800, and the top 37% rate applies only above $768,700.⁷ Bracket boundaries shift each year with inflation.

Local Earned Income Taxes

Some workers face an additional layer at the local level. Municipalities and school districts in several states impose their own earned income tax, usually as a flat percentage of wages rather than a progressive rate. Pennsylvania is the most prominent example: under Act 32, employers withhold a local earned income tax on their employees’ behalf. Various Ohio cities and a handful of other jurisdictions run similar programs.

Rates commonly fall between 1% and 3% of gross wages. If you live in one municipality and work in another, both may claim tax, though many jurisdictions offer a credit for taxes paid to your work location so you’re not fully double-taxed. Your local tax collector’s website is the place to confirm whether a tax applies and at what rate.

The Earned Income Tax Credit

The EITC is refundable, which is what makes it especially valuable. If the credit exceeds what you owe, the IRS pays you the difference. For 2026, the maximum credit amounts are:⁷

No qualifying children: $664
One qualifying child: $4,427
Two qualifying children: $7,316
Three or more qualifying children: $8,231

To claim it, you need earned income under set annual thresholds that vary with your filing status and number of qualifying children. You, your spouse (on a joint return), and every child you claim must have a valid Social Security number.⁸ Your investment income has to stay under a cap: $11,950 for tax year 2025, with a slightly higher figure expected for 2026.⁹

A qualifying child must pass four tests: age, relationship, residency, and joint return. Under 19 at year-end, or under 24 if a full-time student for at least five months of the year; a permanently and totally disabled child qualifies at any age. Relationship covers your son, daughter, stepchild, adopted child, foster child, sibling, or a descendant of any of them. Residency means the child lived with you in the United States for more than half the year.¹⁰

You can still claim a smaller EITC without children, but the age window is narrow: at least 25 and under 65 at year-end, with your main home in the United States for more than half the year, and you can’t be claimed as a dependent on someone else’s return.⁸

The credit doesn’t stay at its maximum across all incomes. It phases in as your earned income rises, holds steady through a middle range, then phases out until it disappears. For tax year 2025, the maximum adjusted gross income to qualify ran from $19,104 (single filer, no children) up to $68,675 (married filing jointly, three or more children).⁹ The 2026 thresholds will be slightly higher after inflation adjustments. Married couples filing jointly get a higher phase-out starting point than single filers, so the credit lasts further up the income ladder.¹¹

Forms You’ll Receive

The paperwork depends on how you earn.

Form W-2 arrives from your employer by the end of January, showing your total wages and the federal, state, and local taxes withheld. Box 1 is your taxable wages; Boxes 15 through 20 cover state and local details. Compare Box 1 against your final pay stub before you file, because discrepancies do happen.¹²

Form 1099-NEC comes from any single payer who paid you $600 or more as an independent contractor. Amounts under $600 are still taxable; the threshold just decides whether the payer has to report them.¹³

Form 1099-K is issued by payment apps and online marketplaces once your payments for goods or services exceed $20,000 across more than 200 transactions in a calendar year. Below that, you still owe tax on the income; the platform just doesn’t file the form.¹⁴

If any form has errors, contact the issuer for a corrected version before filing. Numbers on your return that don’t match what the IRS received from your employer or client are a fast way to trigger a notice or delay a refund.

Estimated Tax Payments if You’re Self-Employed

Employees have taxes withheld each paycheck. Self-employed workers don’t. If you expect to owe $1,000 or more when you file, the IRS requires quarterly estimated tax payments during the year rather than one lump sum in April.¹⁵

The year splits into four payment periods, each with its own deadline. Missing one can bring an underpayment penalty even if you end up with a refund at filing. The penalty depends on how much was underpaid, how long, and the IRS’s published quarterly interest rates.¹⁶ First-year self-employed filers are often caught out by the size of the bill, which combines income tax with the full 15.3% self-employment tax.

Penalties

Filing late and paying late are separate penalties, and they stack. Failure to file is 5% of unpaid tax for each month or partial month the return is late, capped at 25%.¹⁷ Failure to pay runs 0.5% per month, also capped at 25%.¹⁸ If you can’t pay in full, file anyway; the filing penalty is ten times more expensive per month than the payment penalty.

EITC errors have their own consequences. If the IRS finds you claimed the credit through reckless or intentional disregard of the rules, you’re banned from claiming it for two years after the determination. A fraudulent claim extends the ban to ten years.¹¹ Even an honest mistake caught through the deficiency process means you’ll need to submit additional documentation to prove eligibility on any future EITC claim.
