Federal Income Tax = Sum of (Taxable Income × Tax Rate) for each applicable bracket

The calculator uses the official 2024 tax brackets published by the IRS. These brackets are progressive, meaning higher income levels are taxed at higher rates.

The 2024 federal income tax brackets are as follows:

Filing Status	10% Bracket	12% Bracket	22% Bracket	24% Bracket	32% Bracket	35% Bracket	37% Bracket
Single	$0 - $11,600	$11,601 - $47,150	$47,151 - $100,525	$100,526 - $191,950	$191,951 - $243,725	$243,726 - $609,350	$609,351+

These brackets are subject to change each year. Always verify with the IRS for the most current information.

Standard Deduction vs Itemized Deduction

You can choose between a standard deduction or itemizing your deductions:

Filing Status	Standard Deduction (2024)
Single	$14,600
Married Filing Jointly	$29,200
Head of Household	$21,900

Itemizing deductions can be beneficial if your total itemized deductions exceed your standard deduction. Common itemized deductions include:

Mortgage interest
State and local taxes
Medical expenses
Charitable donations
Casualty or theft losses

Common Tax Credits and Deductions

In addition to deductions, there are several tax credits that can reduce your tax liability:

Child Tax Credit ($2,000 per qualifying child)
Earned Income Tax Credit (up to $6,960 for individuals)
American Opportunity Credit (up to $2,500 per eligible student)
Lifetime Learning Credit (up to $2,000 per eligible student)
Child and Dependent Care Credit (up to 35% of eligible expenses)

Credits directly reduce your tax owed, while deductions reduce your taxable income. Credits are generally more valuable than deductions of the same amount.

Example Calculation

Let's calculate the federal tax for a single filer with $60,000 taxable income:

$0 - $11,600 at 10% = $1,160
$11,601 - $47,150 at 12% = $4,125
$47,151 - $60,000 at 22% = $2,855

Total federal income tax = $1,160 + $4,125 + $2,855 = $8,140

Worked Example

For $60,000 taxable income:

First $11,600 × 10% = $1,160
Next $35,550 × 12% = $4,266
Remaining $12,850 × 22% = $2,827
Total = $1,160 + $4,266 + $2,827 = $8,253
