I have a 1 participant 401k/PS (sole prop.) plan that received 100% of excess assets from a terminated DB plan in 2017. Plan was amended as a QRP. The QRP has been funding the ERPS contribution beginning in 2017. The owner/TEE opted to invest these assets as opposed to keeping them in a non-interest bearing account. Year 7 will be 2024 and based on the MV as of today, it looks like there will still be assets remaining in the QRP. Can someone advise me on what the excise tax will be for any remaining assets that revert back to the ER. Is there anything else I should be advising my client on with respect to this situation? Thank you.
