How it works

The Federal Tax Bracket Finder calculates your federal income tax based on the income you provide and your filing status. The calculator uses the current tax brackets set by the IRS to determine your marginal tax rate, effective tax rate, and total federal tax owed. For example, if you input an income of $85,000 and select 'single' as your filing status, the calculator applies the 2023 tax brackets. The first $10,275 is taxed at 10%, the income from $10,276 to $41,775 is taxed at 12%, and income from $41,776 to $89,075 is taxed at 22%. This results in a marginal rate of 22% for the portion of your income above $41,775. Your effective tax rate is calculated by dividing the total tax owed by your total income, providing a clearer picture of your overall tax burden. In this case, your total federal tax would be approximately $14,179, leading to an effective tax rate of around 16.7%.

Tips

  • Keep track of any deductions or credits you may qualify for to reduce your taxable income.
  • Consider adjusting your withholding if you find you owe a lot at tax time or receive a large refund.
  • Review your filing status each year, as changes in your life situation can affect your tax bracket.
  • Stay updated on tax law changes, as brackets and rates can shift annually.
