Generally, the Internal Revenue Service (IRS) requires you to make quarterly estimated tax payments for the current tax year if both of the following apply:

  • you expect to owe at least $1,000 in federal tax for the current tax year, after subtracting federal tax withholding and refundable credits, and
  • you expect federal withholding and refundable credits to be less than the smaller of:
    • 90% of the tax to be shown on your current year’s federal tax return, or
    • 100% of the tax shown on your prior year’s federal tax return (only applies if your prior year tax return covered 12 months - otherwise refer to 90% rule above only).

To calculate your federal quarterly estimated tax payments, you must estimate your adjusted gross income, taxable income, taxes, deductions, and credits for the current year.  Form 1040-ES includes an Estimated Tax Worksheet to help you calculate your federal estimated tax payments.
