Excise Tax on Refund of Match Deposited as a Lump-Sum after the End of the Plan Year

Hello everyone,

Does the 10% excise tax apply to the post March 15th refund of a discretionary match that was calculated and deposited as a lump-sum after the end of the plan year? Thank you all. As always, I appreciate your assitance.

Refunds of excess contributions (deferrals) and excess aggregate contributions (matching) after March 15 are subject to the 10% excise tax.
