Below are the steps to calculate estimated taxes for next year. 

  1. From within your TaxAct return (Online or Desktop), click Federal. On smaller devices, click the Menu icon then click Federal
  2. Click 2020 Estimated Tax Payments in the Federal Quick Q&A Topics menu
  3. Click Yes to review the requirements for making estimated tax payments
  4. Select either Use worksheet calculation or Pay 110% of 2019 tax liability (100% if your adjusted gross income did not exceed the threshold) then click Continue
  5. The program will proceed with the interview questions for you to enter the appropriate information. You must enter your estimated earnings in the 2020 year column (using the 2019 column amounts for reference) in order to calculate the estimated tax amount to pay.

Note: The method of paying 110% (or 100%) of the current year's tax liability is only to avoid the interest penalty for underpaying your taxes in the following year. In the TaxAct program, this amount is calculated on Federal Form 2210, Line 4-Current year tax.  Use the worksheet method to estimate tax for the following year if you wish to cover all of the estimated tax that will be due on that return.

After you have completed the Estimated Tax Payments section of the Q&A, you have the option to print Form 1040-ES, which includes the quarterly vouchers, and mail the payments or electronically pay the amounts due (both methods are outlined below).


Print vouchers and mail payments:
