2019 Federal Quarterly Estimated Tax Payments

Generally, the Internal Revenue Service (IRS) requires you to make quarterly estimated tax payments for calendar year 2019 if both of the following apply:

  • you expect to owe at least $1,000 in federal tax for 2019, 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 2019 federal tax return, or
    • 100% of the tax shown on your 2018 federal tax return (only applies if your 2018 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 calendar year 2019.  Form 1040-ES includes an Estimated Tax Worksheet to help you calculate your federal estimated tax payments.
