How Federal Income Tax Works

The federal income tax is progressive, meaning higher portions of your income are taxed at higher rates. Your tax is not calculated by applying one rate to your entire income. Instead, your taxable income (gross income minus deductions) flows through each bracket sequentially.

Standard Deduction

Before applying the brackets, you subtract either the standard deduction or your itemized deductions (whichever is larger). For 2026, the standard deduction is:

  • Single: $16,100
  • Married Filing Jointly: $32,200
  • Head of Household: $24,150
  • Married Filing Separately: $16,100

Progressive Bracket Calculation

After deductions, your taxable income fills each bracket from the bottom up. The first $12,400 of taxable income (single) is taxed at just 10.00%. The next segment up to $50,400 is taxed at 12.00%, and so on. Your marginal rate is the rate on your last dollar; your effective rate (total tax / gross income) is always lower. To compare the two side by side, with 401(k), HSA and OBBBA deductions, use the effective tax rate calculator.

Worked Examples

Example 1: Single Filer, $75,000 Gross Income

Profile: Single filer, $75,000 gross income, standard deduction

Gross income = $75,000.00
Standard deduction = $16,100.00
Taxable income = $58,900.00
10.00% on $12,400.00 = $1,240.00
12.00% on $38,000.00 = $4,560.00
22.00% on $8,500.00 = $1,870.00
Total tax = $7,670.00 (effective rate 10.23%, marginal rate 22.00%)

Example 2: Married Filing Jointly, $150,000 Gross Income

Profile: Married filing jointly, $150,000 gross income, standard deduction

Gross income = $150,000.00
Standard deduction = $32,200.00
Taxable income = $117,800.00
10.00% on $24,800.00 = $2,480.00
12.00% on $76,000.00 = $9,120.00
22.00% on $17,000.00 = $3,740.00
Total tax = $15,340.00 (effective rate 10.23%, marginal rate 22.00%)

Example 3: Single Filer, $250,000 Gross Income

Profile: Single filer, $250,000 gross income, standard deduction

Gross income = $250,000.00
Standard deduction = $16,100.00
Taxable income = $233,900.00
10.00% on $12,400.00 = $1,240.00
12.00% on $38,000.00 = $4,560.00
22.00% on $55,300.00 = $12,166.00
24.00% on $96,075.00 = $23,058.00
32.00% on $32,125.00 = $10,280.00
Total tax = $51,304.00 (effective rate 20.52%, marginal rate 32.00%)

Frequently Asked Questions

How do federal income tax brackets work?
The U.S. uses a progressive tax system. Your income is divided into segments (brackets), and each segment is taxed at a different rate. Only the income within each bracket is taxed at that bracket's rate, not your entire income. For example, a single filer earning $75,000 doesn't pay 22.00% on all $75,000; instead, the first $12,400 is taxed at 10.00%, the next portion at 12.00%, and so on.
What changed in the 2026 federal income tax brackets?
For 2026, the IRS adjusted all bracket thresholds and the standard deduction for inflation under Rev. Proc. 2025-32. The standard deduction increased to $16,100 for single filers and $32,200 for married filing jointly. The OBBBA (One Big Beautiful Bill Act) preserved the lower TCJA bracket rates (10%, 12%, 22%, 24%, 32%, 35%, 37%) through 2028.
What is the standard deduction for 2026?
The 2026 standard deduction is $16,100 for single filers, $32,200 for married filing jointly, $24,150 for head of household, and $16,100 for married filing separately. Additional amounts apply for taxpayers age 65+ or who are blind.
What is the difference between marginal and effective tax rate?
Your marginal tax rate is the rate applied to your last dollar of taxable income, it determines the bracket you fall into. Your effective tax rate is your total tax divided by your total gross income, representing the actual percentage of income you pay in federal tax. The effective rate is always lower than the marginal rate in a progressive system because lower brackets are taxed at lower rates.
Does this calculator include state income tax or FICA?
No. This calculator estimates federal income tax only. It does not include state or local income taxes, Social Security tax (6.2%), Medicare tax (1.45%), or any credits or additional deductions beyond the standard deduction. Use our state-specific calculators for a more complete picture.
Should I use the standard deduction or itemize?
Most taxpayers benefit from the standard deduction. For 2026, you should itemize only if your total itemized deductions (mortgage interest, state/local taxes up to the SALT cap, charitable donations, etc.) exceed the standard deduction of $16,100 (single) or $32,200 (MFJ). About 90% of filers use the standard deduction.
How is taxable income calculated?
Taxable income = gross income minus deductions. If you take the standard deduction, it's simply your gross income minus $16,100 (single) or $32,200 (MFJ). If you itemize, you subtract your total itemized deductions instead. Above-the-line deductions (like IRA contributions, student loan interest, or the new OBBBA overtime/tips deductions) reduce your gross income before the standard deduction is applied.
