Can the deferral amount used for ADP test be reduced by the available catch up for the year on the front end? For example, have a catch-up eligible participant that deferred $27,000 during 2024. The deferral amount used for the ADP test was $23,000 (401(a)(30) limit for 2024). Since the participant is catch-up eligible can $7,500 of the $23000 be classified as catch-up reducing the amount used for the ADP test to $15,500 ($23000-$7500)?
