Find it yourself

The Form 5472 due date, found, not guessed.

We're not going to hand you a date that might be stale. Here's how to find the one that applies to your company.

a due date is a date that belongs on the calendar, not a marketing page

Why we're not printing a date.

The due date is not a single universal date — it is computed from your company's tax year, and the rules around it have shifted over time. A page that prints one calendar date is only right for some readers, and only until the next change. For a filing where the penalty stacks per form and per year, "close enough" isn't.

The good news is that the source states it plainly. You don't need to decode anything — you just need to know where to look.

The source: the IRS instructions.

The Instructions for Form 5472 are the primary source — the "When To File" section states the deadline in terms of your company's tax return. The About Form 5472 page is the shorter overview.

If you're not yet sure the form applies to you at all, check who must file Form 5472 before you worry about a deadline.

What to look for when you get there.

  1. 01

    The “When To File” section

    The instructions have a section that states exactly when the form must be filed. That section is written to be followed, not summarized — read it directly.

  2. 02

    How the due date ties to your tax return

    Form 5472 is filed with the company's income tax return, so its due date is set relative to that return's due date. If you know when your return is due, the 5472 answer is right next to it.

  3. 03

    Whether your tax year is calendar or fiscal

    The due date is computed from your company's tax-year end. Most companies are on a calendar year, but if you elected a fiscal year, your deadline lands on a different calendar date.

What it depends on in your case.

Your deadline is a function of two things: your company's tax year (calendar or fiscal) and your company's income tax return due date. Once you know those two, the 5472 due date follows from the instructions without any guesswork.

And the flip side of the date is the penalty for missing it — the Form 5472 penalty, looked up properly, so you know what a miss actually costs. We form the entity, but 5472 is a tax filing you'll want a professional to help with — the Form 5472 guide sets out who does what.

Formed right, from day one.

We handle your US formation so the entity and its tax year start off correct — then we point you to the filings that are still yours.
