Plain English

Form 5330 vs Form 5500

Both relate to plans but serve different purposes

Need for attachment

Whether a statement is required

→ Always attach a detailed explanation of the violation

Prior payments

Whether to include prior tax payments

→ Include only payments made toward the same excise tax liability

Electronic filing
