This calculator uses progressive tax brackets and the standard deduction for the current tax year. It does not account for itemized deductions, tax credits, or state taxes.
Federal Income Tax Brackets
The federal income tax is progressive, meaning higher income levels are taxed at higher rates. For the 2023 tax year, the brackets for single filers are:
| Income Range | Tax Rate |
|---|---|
| $0 - $10,275 | 10% |
| $10,276 - $41,775 | 12% |
| $41,776 - $89,075 | 22% |
| $89,076 - $170,050 | 24% |
| $170,051 - $215,950 | 32% |
| $215,951 - $539,900 | 35% |
| $539,901+ | 37% |
The standard deduction for single filers in 2023 is $13,850, which reduces your taxable income.
Standard Deduction
The standard deduction is a fixed amount that reduces your taxable income. For single filers in 2023, it's $13,850. This means your first $13,850 of income is not subject to federal income tax.
For example, if you earn $50,000 and your standard deduction is $13,850, your taxable income would be $36,150.
Example Calculation
Let's calculate the federal income tax for a single filer with $50,000 in gross income:
- Subtract the standard deduction: $50,000 - $13,850 = $36,150 taxable income
- Apply the tax brackets:
- $10,275 at 10% = $1,027.50
- $31,495 at 12% = $3,779.40
- Total tax = $1,027.50 + $3,779.40 = $4,806.90
Therefore, the estimated federal income tax for this example is $4,806.90.
