What's my 2018 federal income tax bracket? How much income tax will I need to pay this tax year? TaxAct's free tax bracket calculator is a simple, easy way to estimate your federal income tax bracket and total tax.

How to calculate my tax bracket?

Follow these steps to calculate your federal income tax bracket:

  1. Select your federal tax filing status (most married couples benefit by filing jointly)
  2. Enter your total, gross income (TaxAct will automatically estimate the taxable portion of your income)
  3. Add any 401(k) and IRA pre-tax contributions (employer-sponsored retirement plan)
  4. List any pre-tax childcare contributions
  5. If you expect your total itemized deductions to total an amount larger than the standard deduction, replace the standard deduction amount with your total itemized deductions
