Here is the scenario. You filed your 1040 on February 1 in the hopes of getting your refund fast. Three weeks later you receive a 1099 in the mail that was not included on your return. Worse, it was for a sizable amount of money that you had assumed was non-taxable since the 1099 was not received in January. Without a doubt, the IRS is going to hit you with a balance due. What’s more, the 20% accuracy penalty is going to be assessed on top of that. Are you up the creek without a paddle?
Not necessarily. The Internal Revenue Manual 21.6.7.4.10 (03-18-2022) refers to “Superseding Returns” and defines these as either an amended return (1040-X) or a corrected (duplicate) return filed after the first return but before the April 15th due date. This IRM requires IRS employees to adjust their databases to reflect the corrected return information. (Hint: It would be a great idea to write “Superseding Return” at the top of the new tax return). The fact that you have correctly filed your return by the due date removes the potential for any penalties other than failure to pay and estimated tax penalties.
This procedure does have an important limitation. While you can correct income and deductions, you cannot modify any irrevocable elections that were made on the first return. Elections such as filing jointly are irrevocable and cannot be reversed with a superseding return.
