I just discovered I should have filed Form 5472 three years ago — is it too late?

Review the entity's classification, transaction history, filing history, current IRS instructions, and any IRS correspondence promptly. If delinquent filings are required, the appropriate submission and any request for relief depend on the facts and IRS procedures. The IRS determines penalty applicability and relief.

Should I wait to hear from the IRS before filing?

Do not ignore an unresolved filing question or an IRS notice. The appropriate timing and procedure depend on the facts, current IRS guidance, and whether the IRS has already contacted the taxpayer. A qualified professional can help assess the available options; no approach guarantees an outcome.

Can I file all my delinquent years in one submission?

Keep records and forms clearly separated by tax year. The appropriate packaging and submission method depend on the current IRS instructions and the taxpayer's circumstances. Confirm the procedure before sending a multi-year submission.

What if I don't know all the transaction amounts from prior years?

Gather the best available documentation: bank statements, PayPal/Stripe records, invoices, wire transfer records. If exact amounts are unavailable for older transactions, use reasonable estimates and note in your Reasonable Cause statement that you are providing best available estimates. The IRS accepts good-faith estimates when supported by available documentation.
