What do audited Brooklyn plans report?

40% of the 129 audited Brooklyn 401(k) plans that answered the question reported employee contributions reaching the plan late on Schedule H. Late deposits are one of the things an auditor tests; what else a first auditor looks at.

On fees: New York plans that paid their audit from plan assets reported a median of $18,630 in 2024, and half paid between $12,376 and $30,527, across 667 filings. Plans that pay from company funds report no fee, so this is the going rate among plans that pay from the plan. The full fee index.
