just loaded 8.3 and the adp test is applying CUD's to nhce's adp % when the adp test fails(deferred $2800 and is only using $800 in the test). there is no other limit the nhce is exceeding(402g, 415 or plan limit). The effective date for CUD's is in census but i don't understand why it affects the nhce?

check the compensation you have entered for the participant. i have had pay issues( eligible pay incorrect, etc.) that affect the deferral amount and create catch ups

there was no computed comp int he deferral field --that was the cause. thanks
