What you get

The forms, and the receipt
that says they arrived.

Form 5472 is never filed alone. It travels attached to a pro forma Form 1120, and it goes to a fax line the IRS keeps for foreign-owned disregarded entities. What comes back is the cheapest proof of timely filing you will ever hold.

Pro forma IRS Form 1120, the return the 5472 is attached to

Behind on years

Every year you missed,
in one submission.

Filing late beats not filing, and filing before the IRS contacts you matters: their notice is what starts the 90-day clock that adds another $25,000 every 30 days.

Select the years you have not filed

Exposure at $25,000 per year$0Every year is a separate form, and a separate penalty.

Multi-year catch-up

Every year from 2019 to 2025, prepared and sent as one package.

Reasonable cause statement

Each late year carries its own explanation, which is the relief route the IRS actually reads.

Extensions and corrections

Form 7004 to extend, and amended filings when a prior year had the wrong numbers.
