Form 5472 Penalty Reality Check
  • Automatic $25,000 Fine: The IRS assesses an automatic initial penalty of $25,000 per unfiled Form 5472 per year.
  • Applies to $0 Income LLCs: Fines apply regardless of revenue or profit. $0 revenue does NOT exempt you.
  • 90-Day Continuation Penalties: An additional $25,000 fine is added for every 30-day period the failure continues after IRS notification.
  • Abatement Relief Available: Taxpayers can submit a formal Reasonable Cause statement under Treas. Reg. 1.6038A-4(b) to request penalty cancellation.

1. The IRS $25,000 Penalty Structure Explained

In 2018, the US Congress increased the base penalty under Internal Revenue Code Section 6038A(d) from $10,000 to $25,000 per violation.

Because foreign-owned single-member LLCs are treated as reporting entities, failing to submit Form 5472 by April 15 results in an automatic system-generated penalty notice sent to the company.

2. What Is IRS Notice CP215 / CP15?

Notice CP215 is the official penalty assessment letter mailed by the IRS to inform the LLC that a $25,000 penalty has been charged to its account.

The notice specifies a payment due date and outlines your right to appeal or submit a written request for penalty relief.

3. The 90-Day Escalation Clause ($25,000 / 30 Days)

If you ignore Notice CP215 for more than 90 days after issuance, the IRS imposes an additional $25,000 continuation penalty for every 30 days the return remains unfiled, with no upper cap.

4. How to Claim Reasonable Cause Penalty Abatement

Under Treasury Regulation Section 1.6038A-4(b), the $25,000 penalty will be canceled if you demonstrate that the failure was due to Reasonable Cause and not willful neglect.

Reasonable Cause arguments include:

  • Honest misunderstanding of complex US international tax laws by a first-time foreign founder.
  • Reliance on incorrect advice from a certified tax professional.
  • Serious illness, natural disaster, or severe international mail disruption.
