Step 1 of 6 · Who owes the tax
Form 5330 — Section A: Prohibited transactions and contribution taxes
Nondeductible contributions, excess 403(b)(7)(A) custodial-account contributions, prohibited transactions with a disqualified person, disqualified welfare benefits, ESOP dispositions, and prohibited ESOP allocations.
This return reports Section A taxes only.
A Form 5330 may report the taxes of one section. If you also owe an excise tax from another section, it has its own due date and needs its own Form 5330 — start a second one from the section list.
Due: The last day of the 7th month after the end of the tax year of the employer (or other person who must file this return).
Who owes the tax
Form 5330 is filed by the person or entity liable for the excise tax — which is not always the plan or its sponsor. Give the EIN for an entity, or the SSN if an individual owes the tax.
