Completing Form 14420, Verification of Reported Income

The IRS provides a new two-page form to reply to Letter 5039: Form 14420, Verification of Reported Income. The form requests:

  • Verification of the accuracy of Forms 1099-K filed under your client’s name
  • Estimates of gross sales by Form 1099-K reportable transaction categories (such as online, phone or catalog, gift cards, lottery tickets) to explain why the portion of gross receipts is higher than expected
  • Information on other individuals or businesses that shared a card terminal with your client and would have received merchant card receipts reported on your client’s account

The IRS estimates that it will take three to six hours to prepare, copy and send Form 14420 to the IRS. The IRS expects to use Letter 5039 and Form 14420 in 5,600 pilot cases for 2011 returns. This could be a costly letter for your clients, when you consider the time needed to analyze your clients’ records used to prepare the return.
