Compliance Warning

Common Form 5472 mistakes that trigger penalties

Foreign-owned single-member LLCs face an automatic $25,000 IRS penalty for failing to file a complete, accurate, and timely Form 5472. Here are the most common errors to avoid.

1. Late Filing and Deadline Mismanagement

The primary trigger for the $25,000 penalty is missing the annual deadline (typically April 15th). The IRS assesses this automatically upon late receipt.

  • Automatic Assessment: It does not require an audit to trigger.
  • Invalid Extensions: Form 5472 is an attachment to Form 1120. To extend the deadline, you must submit a Form 7004 extension for the "parent" Form 1120 by April 15th.
  • Wrong Address: Mailing the form to the standard 1120 address instead of the dedicated Ogden, Utah address for foreign-owned LLCs.

2. Missing Reportable Transactions ("The Dormant Myth")

Many founders believe that if their LLC had no revenue, they don't have to file. This is a critical error. Almost any movement of value is a reportable transaction.

  • Capital Contributions: Using personal funds to pay for state filing fees, registered agents, or initial bank deposits.
  • Owner Draws: Any funds transferred from the LLC back to the owner's personal accounts.
  • Missing Supporting Statements: Failing to attach a "Federal Supporting Statement" that describes these transactions makes the form "substantially incomplete," triggering the failure-to-file penalty.

3. Incorrect Entity Classification & Technical Errors

Even if filed on time, technical inaccuracies or using the wrong forms can invalidate the entire filing.

  • Filling out the entire 1120: Disregarded entities must only file a "pro-forma" Form 1120 as a cover sheet, leaving the income and expense sections blank.
  • Missing Required Labeling: Failing to write "Foreign-owned U.S. DE" across the top of the Form 1120.
  • Inconsistent Reference IDs: If you don't have a U.S. TIN/ITIN, you must use the exact same foreign Reference ID Number consistently every year.
