5472 Penalties

If you sell to U.S. customers through a U.S. entity, Form 5472 rules may apply to you. Missing this form can trigger a steep penalty. This post explains what is at stake and what recent guidance says about fixing a problem.

What Is Form 5472 and Who Must File It?

Form 5472 reports transactions between certain U.S. businesses and their foreign owners or related parties. A disregarded entity is a business, often a single-member LLC, that the IRS treats as part of its owner for tax purposes.

Under IRC Section 6038A, this filing requirement applies to:

  • U.S. corporations that are 25% or more foreign owned
  • Foreign-owned U.S. disregarded entities engaged in a U.S. trade or business
  • Related parties that had reportable transactions during the year

Many foreign e-commerce sellers use a U.S. LLC to hold a bank account or process payments. That structure can create a Form 5472 filing duty, even with no U.S. tax due. The form is filed with a pro forma Form 1120, a U.S. corporate return used only as a cover sheet for this purpose.

How Much Is the Penalty for Missing Form 5472?

The penalty is significant. Under IRC Section 6038A(d), the IRS can assess $25,000 for a late, incomplete, or missing Form 5472. If the failure continues after IRS notice, an additional $25,000 penalty can apply for each 30-day period, starting 90 days after that notice.

This penalty applies per related party, per year. A business with several related-party transactions can face multiple $25,000 penalties for a single tax year.

Beware of Quick Fixes

Some preparers promise an easy way to remove this penalty. Be cautious of that promise.

The IRS reviews each penalty abatement request on its own facts. A generic explanation rarely qualifies for relief. Filing a late Form 5472 without a specific, documented reason can leave the penalty in place.

What New IRS Guidance Says

The IRS Office of Chief Counsel has issued guidance addressing how it evaluates reasonable cause claims for late Form 5472 filings. The guidance points toward a fact-specific review rather than a standard excuse.

If you missed a filing, gather your specific facts before you respond to any IRS notice. Do not rely on a template excuse letter.

Plan Ahead

Review your U.S. entity structure now, before a filing deadline passes. If you already missed a Form 5472 deadline, document the facts right away.
