A 2024 I&D return, or any earlier year’s return that has not been filed, is still required. Periods that started on or before December 31, 2024 also stay open to audit and collection, so keep the workpapers.
Do not send 2025 estimated I&D payments. A client who paid them in error has to ask the department for a refund in writing.
- Remove the I&D return from your 2025 engagement letters.
- Check prior-year client files for unfiled I&D years before closing them out.
- Watch for clients still scheduling estimate payments out of habit.
