Pulse Analysis

The tax landscape for 2025‑2026 has been reshaped by a suite of retroactive provisions that allow taxpayers to revisit already‑filed returns. This unprecedented flexibility stems from legislation that retroactively amends the rules governing superseding returns, business interest expense deductions, and research‑development credits. For preparers, the ability to undo prior elections—often likened to a tax "mulligan"—means that strategic timing and documentation become critical, especially as the IRS tightens its scrutiny of amendment processes.

Key sections of the new law, such as the OBBBA (Obligation‑Based Business Benefit Act), introduce fresh cost‑recovery choices and timing traps that can dramatically alter a company’s depreciation schedule. Simultaneously, the resurgence of COVID‑related ERC litigation and the clarification of the tax benefit rule create both risk and refund potential for firms that over‑claimed wages. Business interest expense deductions are also in flux, with the IRS permitting certain elections to be reversed, thereby unlocking additional deductions for qualifying entities. These changes collectively raise the stakes for accurate, forward‑looking tax planning.
