How the USA Tax Calculator Works
The USA Tax Calculator estimates your federal income tax based on your taxable income. The calculation follows the progressive tax system used by the Internal Revenue Service (IRS).
Formula Used
The calculator applies the following tax brackets for the 2023 tax year:
- 10% on income up to $11,000
- 12% on income between $11,001 and $44,725
- 22% on income between $44,726 and $95,375
- 24% on income between $95,376 and $182,100
- 32% on income between $182,101 and $231,250
- 35% on income between $231,251 and $578,125
- 37% on income over $578,125
The calculator sums the tax owed in each bracket to determine your total federal income tax. It does not account for state taxes, deductions, credits, or other tax-saving strategies.

Federal Income Tax Brackets
The federal income tax system uses progressive tax brackets, meaning higher income levels are taxed at higher rates. Here are the 2023 tax brackets for single filers:
| Taxable Income Range | Tax Rate |
|---|---|
| $0 - $11,000 | 10% |
| $11,001 - $44,725 | 12% |
| $44,726 - $95,375 | 22% |
| $95,376 - $182,100 | 24% |
| $182,101 - $231,250 | 32% |
| $231,251 - $578,125 | 35% |
| $578,125+ | 37% |
Married filing jointly filers have different brackets, and other filing statuses have their own tax brackets. This calculator uses the single filer brackets by default.
Worked Examples
Example 1: $30,000 Taxable Income
For a single filer with $30,000 in taxable income:
- $11,000 × 10% = $1,100
- ($30,000 - $11,000) × 12% = $2,148
- Total tax = $1,100 + $2,148 = $3,248
Example 2: $100,000 Taxable Income
For a single filer with $100,000 in taxable income:
- $11,000 × 10% = $1,100
- ($44,725 - $11,000) × 12% = $3,646
- ($100,000 - $44,725) × 22% = $12,111
- Total tax = $1,100 + $3,646 + $12,111 = $16,857
