Extended Your Form 5472? October 15 Is the Real Deadline
If you filed Form 7004 back in April, your foreign-owned LLC’s Form 5472 with the pro forma Form 1120 is due October 15. Two things make this deadline different from the one you already moved:
- There is no second extension. Form 7004 grants one six-month extension per year. October 15 is the end of the road.
- The submission is physical. For a foreign-owned disregarded LLC this package cannot be e-filed — it goes by fax or mail to the IRS in Ogden, Utah. That adds real transmission time you need to plan for.
The timeline, worked backwards
The return has to be prepared, reviewed, signed, and transmitted by October 15. Working backwards from that:
| If your documents are complete by | You are |
|---|---|
| October 7 | Comfortable — standard preparation (5 business days) finishes with room to spare |
| October 13 | Still fine with express preparation (+$149) — 48 hours, subject to available slots |
| After October 13 | Cutting it close — talk to us the same day |
“Complete documents” for most single-member LLCs means: the EIN letter, formation documents, owner identification, and a record of the money that moved between you and the company during the tax year — contributions, draws, and company costs you paid personally. Bank or platform statements are enough to start. Our Form 5472 service covers the rest.
If October 15 passes without a filing
The return becomes delinquent and the exposure is the $25,000 penalty under IRC §6038A — the same one that applies to an unfiled return with no extension at all.
Two facts should shape what you do next:
- The escalating penalty has not started yet. The continuation penalty — another $25,000 per 30 days — only begins 90 days after the IRS sends a notice. Before any notice, the clock is not running.
- Filing before the IRS contacts you is the single strongest fact in a reasonable cause request. It is the difference between correcting something yourself and being caught.
That is exactly what our past-due Form 5472 service is for: the complete filing with a written reasonable cause statement, $449 per tax year. We prepare and submit the request properly; whether the IRS grants relief is the IRS’s decision — be wary of anyone who promises otherwise.
If you never filed Form 7004
Then the April deadline already passed, and October 15 is not your date — you are in past-due territory now. The good news is the same as above: before an IRS notice, acting first is what matters.
