What Is the Form 5472 Filing Deadline?

The form 5472 filing deadline generally follows the due date of the U.S. income tax return with which Form 5472 is required to be filed. For a foreign-owned U.S. disregarded entity, Form 5472 is generally filed with a pro forma Form 1120. The standard due date is generally the 15th day of the fourth month after the end of the entity's tax year. The final short-year return's due date is generally the 15th day of the fourth month after the dissolution date.

For a calendar-year foreign-owned LLC, this generally means the filing is due on April 15 of the following year. If April 15 falls on a weekend or legal holiday, the deadline moves to the next business day.

Knowing the deadline matters because failing to file Form 5472 when required can result in significant penalties. Planning ahead gives you time to collect your records, complete the forms, review the information, and submit the filing correctly.

Who Needs to Know the IRS Form 5472 Deadline?

The deadline is especially important for foreign-owned U.S. businesses that have a Form 5472 reporting requirement. You may need to track the deadline if you:

  • Own a U.S. single-member LLC from another country
  • Have a foreign-owned U.S. disregarded entity
  • Had reportable transactions with a foreign owner or related party
  • Operate an online or e-commerce business through a U.S. LLC
  • Run a consulting, marketing, software, or other business through a U.S. LLC
  • Are preparing your first Form 5472 filing

Your exact filing obligations depend on your entity classification, ownership, transactions, and tax year. If your business has a different tax year or unusual circumstances, confirm the applicable due date with a qualified tax professional.
