Summary
As part of the implementation of the One Big Beautiful Bill Act (OBBB), the IRS added new fields to form 1040. These changes were implemented in SIPS in Q4 2025. This created a situation where Cashflow and Tax Advisor scenarios for 2025 and all future years in SIPS were created using the previous (now out of date) tax code. This new button in SIPS allows users to easily convert these tax scenarios to the new tax code with minimal effort.
