Form 5472 deadline reminder

A seasonal reminder for foreign-owned single-member LLCs: Form 5472 obligations, the penalty, and how to file on time in 2026.

This is not a government website. Incorporation Bureau is privately owned and is not affiliated with any state business registry, any Secretary of State, or the IRS. You can file directly with the official registry yourself.

A dated, seasonal nudge — the kind of thing a blog does well and a guide can't. Foreign-owned single-member LLCs must file Form 5472 each year, and the penalty for missing it is severe.

The reminder

If you own a US single-member LLC from abroad and had a reportable transaction, you likely must file Form 5472 with a pro-forma 1120. The penalty for failing to file is $25,000.

Our evergreen Form 5472 guide explains who must file, what triggers it, and how to handle it. This post just exists to remind you as the deadline approaches each year.
