No... how would the software know what was earned when?

You have to do the math, and enter the appropriate info on the penalties screen (Screen 8 - Annualized Income Installment Method tho I find that wording a bit odd).  IF your client has self-employment income, don't miss entering that info too.

Thank you.  I would assume the same way that the underpayment penalty is calculated.  If that information is available based on the income and expenses I inputted, my hope was to find that calculation and adjust it based on when earnings were actually posted during the year.

The underpayment penalty is computed by dividing the liability (or the PR/YR safe harbor) by 4 & then comparing it to payments made and the dates made.

YOU have to tell the software that the income (& therefore liability) isn't earned equally thru-out the year.
