What are the federal tax rates for 2018?

Below are the federal tax rate formulas for next year's 2018 returns. Please note that the formulas apply to 2018 taxable income (your gross income minus your standard or itemized deduction, retirement contributions, alimony, student loan interest, and certain other subtractions).

Also note that the formulas don't take into consideration tax credits that can further reduce your tax bill, such as the EITC or the Child Tax Credit. For a more accurate estimate your 2018 tax bill, use TaxCaster.

Tip:  TurboTax 2017 uses the 2018 federal tax rates when generating estimated tax vouchers and W-4 forms.
