Understanding 2024 Federal Income Tax

Calculating your federal income tax involves understanding tax brackets and your filing status. The U.S. uses a progressive tax system, meaning higher portions of your income are taxed at higher rates. For the 2024 tax year, the IRS has updated tax brackets and standard deduction amounts.

How Federal Income Tax is Calculated:

The basic formula is:
Taxable Income – (Deductions & Exemptions) = Adjusted Gross Income (AGI)
AGI – Standard Deduction (or Itemized Deductions) = Your Taxable Income
Your Taxable Income is then applied to the relevant tax brackets for your filing status to determine your tax liability.
