What is it?
The US Income Tax Calculator estimates your 2024 federal income tax using the progressive bracket system for single filers. It shows your effective rate (what you actually pay as a percentage of gross income) vs. your marginal rate (the bracket your last dollar falls into).
How to use
Enter your total gross income and deductions. The default deduction of $14,600 is the 2024 standard deduction for single filers. If you itemize and your itemized deductions exceed the standard, enter that higher amount instead. The calculator computes taxable income and applies each bracket progressively.
Example scenario
With $75,000 gross income and the $14,600 standard deduction, taxable income is $60,400. Federal tax is approximately $8,342. The effective rate is about 11.1% and the marginal bracket is 22%. After-tax income is $66,658 or $5,555/month.
Pro tip
Your marginal rate is not what you pay on all income — only on the last dollars. A 22% marginal bracket does not mean 22% of your income goes to taxes. Maximize pre-tax deductions (401k, HSA, traditional IRA) to shift income out of your highest bracket.
