FAQ

Do I need an EIN?

Yes. Your LLC needs an EIN before completing the Form 1120 + 5472 filing.

Do I need bank statements if there was no bank account?

No bank account means no LLC bank statements, but you should still gather owner-paid expense records and formation records.

Should I keep proof after filing?

Yes. Keep the signed packet and proof that it was sent.

Can this checklist replace professional advice?

No. Use it to prepare records, but get professional advice for complex facts.
