The federal income tax rate for a single person in 2026 runs on a graduated scale from 10% to 37%, spread across seven brackets. Only the dollars inside each bracket are taxed at that bracket’s rate, and a $16,100 standard deduction comes off your gross income before any of the math starts. So the rate on your last dollar earned is almost always higher than the rate you actually pay overall.
2026 Federal Tax Brackets for a Single Filer
The IRS adjusts these thresholds annually for inflation. For the 2026 tax year, single filers fall into one of seven brackets based on taxable income:
- 10% on income from $0 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 everything above $640,600
These figures come from Revenue Procedure 2025-32.1Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026 The rate structure itself is the one originally set by the Tax Cuts and Jobs Act, preserved by recent legislation for 2026.
How the Brackets Actually Apply
Landing in the 22% bracket does not mean 22% of your income goes to the IRS. Each rate applies only to the slice of income that falls inside its range. The first $12,400 is taxed at 10% no matter how much you make. The next slice is taxed at 12%, and so on up the ladder. Your top bracket is simply the rate on your last few dollars.
Take a single filer with $80,000 in taxable income. The first $12,400 is taxed at 10%, or $1,240. The next $38,000 (from $12,401 to $50,400) is taxed at 12%, or $4,560. The remaining $29,600 is taxed at 22%, or $6,512. Total federal income tax: $12,312. That works out to an effective rate of about 15.4%, well below the 22% top bracket. Effective rate is the number that matters for budgeting.
Subtract the Standard Deduction First
Before any bracket math runs, a single filer subtracts the standard deduction from gross income. For 2026, that is $16,100.1Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026 Someone earning $60,000 in gross wages only owes tax on $43,900. That single subtraction often keeps filers a full bracket lower than their salary alone would suggest.
Single filers age 65 or older get an extra deduction. For tax years 2025 through 2028, eligible seniors can claim an additional $6,000, though it begins phasing out at $75,000 in modified adjusted gross income.2Internal Revenue Service. 2026 Filing Season Updates and Resources for Seniors A qualifying 67-year-old with $60,000 in income could subtract $22,100 combined, dropping taxable income to $37,900.
If You Support a Dependent, Check Head of Household
Single people who support a dependent may qualify for head of household status rather than filing as single. Head of household comes with wider brackets and a larger standard deduction. To qualify, you must be unmarried (or considered unmarried by the IRS) on the last day of the year, pay more than half the cost of keeping up your home, and have a qualifying person, usually a child or dependent parent, live with you for more than half the year.3Internal Revenue Service.

Payroll Taxes Come Off Separately
Federal income tax is not the only tax on wages. Every employee also pays FICA: 6.2% for Social Security and 1.45% for Medicare, for a combined 7.65%.5Office of the Law Revision Counsel. 26 USC 3101 – Rate of Tax Your employer matches that amount. FICA applies from the first dollar of wages, with no deduction.
The Social Security portion stops at a wage cap. For 2026, the 6.2% applies only to the first $184,500 of earnings.6Social Security Administration. Contribution and Benefit Base Anything above that is exempt from Social Security tax. The 1.45% Medicare tax has no cap.
Self-employed single filers pay both halves: 12.4% for Social Security and 2.9% for Medicare, totaling 15.3%.7Office of the Law Revision Counsel. 26 USC 1401 – Rate of Tax Half of that self-employment tax is deductible when calculating adjusted gross income.
Extra Taxes Above $200,000
Single filers earning above $200,000 face two surcharges that lower earners never see. The first is the Additional Medicare Tax: 0.9% on wages, compensation, or self-employment income above $200,000, stacked on top of the regular 1.45% Medicare tax.5Office of the Law Revision Counsel. 26 USC 3101 – Rate of Tax The $200,000 trigger is not indexed for inflation.8Internal Revenue Service. Topic No. 560, Additional Medicare Tax
The second is the Net Investment Income Tax: 3.8% on interest, dividends, capital gains, and rental income. It applies to the lesser of your net investment income or the amount by which modified adjusted gross income exceeds $200,000.9Office of the Law Revision Counsel. 26 USC 1411 – Net Investment Income Tax This threshold is also fixed.
Long-Term Capital Gains Use Their Own Rates
Profits from investments held longer than one year are taxed at lower rates than wages. For single filers in 2026, the long-term capital gains rates are:
- 0% on taxable income up to $49,450
- 15% on $49,451 to $545,500
- 20% above $545,500
These thresholds look at total taxable income, not just the gain.10Internal Revenue Service. Revenue Procedure 2025-32 A single filer with $40,000 in taxable income who realizes a $5,000 long-term gain owes 0% on the portion of the gain that keeps total income under $49,450. Short-term gains, on assets held a year or less, are taxed at ordinary income rates.
State Income Tax Adds to the Federal Bill
Federal rates are only part of what a single person owes. Most states impose their own income tax. Eight states charge no individual income tax at all; the rest run from around 2.5% to over 13%. Some use a flat rate; others use progressive brackets. Where you live can swing the combined federal-plus-state effective rate by five or six percentage points on the same income.
Who Has to File
Not every single person needs to file a federal return. Generally, a single filer under 65 must file if gross income exceeds the standard deduction, which is $16,100 for 2026. The threshold is higher for filers 65 and older because of the additional standard deduction. Filing below the threshold is still worthwhile if you had taxes withheld or qualify for a refundable credit.
The 2026 federal return is due April 15, 2027. An automatic six-month extension moves the paperwork deadline to October 15, but any tax owed is still due April 15. Filing late without an extension triggers a failure-to-file penalty, and unpaid tax runs its own interest charges on top.
