So tell me Antitax Man or anyone else. Is the 2019 form 6252 wrong in Part I where it says to "Complete this part for all years of the installment agreement"?  Every other year of form 6252 says  "Complete this part for the year of sale only."  It appears the 2019 form is an IRS typo!!

I thought I was supposed to get a Gross Profit Percentage based on Part I in the YEAR OF SALE ONLY.  Then use that same GPP for all remaining years of Installment sale that I receive payments.

Unless... the IRS wants you to keep the original sale info. in Part I for all years???

Please clarify and Thank you!
