What happens if I miss the Form 5472 deadline?

Missing the Form 5472 deadline triggers an immediate $25,000 penalty per form per tax year under IRC §6038A(d). There is no grace period, and the penalty applies whether the LLC had income or not. After the IRS sends a notice, a continuation penalty of $25,000 per 30-day period begins with no statutory maximum.

Should I still file if I already missed the deadline?

Yes. File as soon as possible. Filing late does not eliminate the initial penalty, but it stops the continuation penalty clock from running further. The IRS views a voluntary late filing more favorably than a complete failure to file when evaluating penalty abatement requests.

There is no “too late” cutoff after which filing becomes pointless. Every day without a filing is a potential additional $25,000 exposure after notice.

Can I get a penalty waiver?

Reasonable cause relief is available under the tax code, but it is not automatic. You must demonstrate that you exercised ordinary business care and prudence but still failed to file. The IRS scrutinizes Form 5472 penalty abatement requests carefully because the form is explicitly an information return with disclosure obligations.

A licensed tax professional must advise on whether a reasonable cause argument applies to your specific facts. This page is educational information only.

How do I file a late Form 5472?

A late Form 5472 is filed the same way as an on-time form: attached to a pro forma Form 1120, mailed to IRS Ogden (or faxed to the IRS fax number for disregarded entities), with the “Foreign-owned U.S. Disregarded Entity” annotation on both forms. The only difference is that the original deadline has passed. For step-by-step guidance, see us5472file.com/late-filing.
