What is a Superseding return?
A superseding return is a replacement tax return filed after the original return but before the original due date (including extensions), allowing taxpayers to make elections or change reporting positions for the same tax period. Under Revenue Procedure 2025-28, the IRS granted automatic six-month extensions for eligible taxpayers to file superseding 2024 returns solely for making One Big Beautiful Bill Act elections or research expenditure method changes. Unlike amended returns, superseding returns completely replace the original filing rather than modifying it, making them valuable for implementing AI-driven R&D tax credits and for optimizing the retroactive treatment of domestic research expenditure.
