Frequently Asked Questions

Form 5472 is an IRS information return required for any U.S. corporation or foreign-owned U.S. disregarded entity that had a reportable transaction with a foreign related party. If you are a non-U.S. person and you own a U.S. single-member LLC, that describes you: the LLC is a disregarded entity and you are a foreign related party. The form is due for any year in which such a transaction occurred, whether or not the LLC had any revenue. In practice that is most years, because the act of forming the LLC and making a capital contribution is itself a reportable transaction, and so is money moving between you and the LLC in either direction.

The requirement is triggered by reportable transactions, not by revenue, so a year with no reportable transactions at all does not require the form. The thing to be careful about is that such a year is rarer than it sounds, and most owners who believe they had one are counting only revenue. Three things to check before you conclude a year was genuinely dormant. First, if you provide management or other services to the LLC, or charge it for anything, that is reportable. Second, state annual fees and registered agent charges paid by the owner on the LLC's behalf are themselves reportable transactions. Third, the downside is lopsided: filing a form you did not strictly need costs you very little, while not filing one you did need means arguing your way out of an automatic $25,000 penalty after the IRS has already sent a notice. If any of the three apply, you had a reportable transaction and the form is due. If after checking you are still unsure, that uncertainty is worth resolving with a tax professional before you decide not to file. The formation year is not in doubt either way, since the initial capital contribution is always reportable.

Reportable transactions include any monetary or non-monetary exchange between the foreign-owned LLC and a foreign related party. This includes capital contributions, distributions, loans, payments for services, rents, royalties, and the LLC formation itself. Even a $1 contribution at formation is reportable.

The IRS imposes an automatic $25,000 penalty for each failure to file or maintain required records for Form 5472. This penalty applies per form, per tax year. A company with two reportable foreign relationships missing three years of filings could face $150,000 in penalties. The penalty is automatic. There is no minimum revenue threshold.

A Pro Forma 1120 is a corporate tax return that a foreign-owned single-member LLC uses solely as a transmittal document for Form 5472. The LLC is a disregarded entity not otherwise required to file a corporate return, so the Pro Forma 1120 exists only to give Form 5472 a vehicle for submission. The IRS requires them to be attached together. Form 5472 cannot be filed on its own.

For a calendar-year LLC, which is almost all of them, the deadline is April 15 of the year following the tax year being reported. If your LLC uses a fiscal year instead, the deadline is the 15th day of the 4th month after your tax year ends. If the date falls on a weekend or holiday, it shifts to the next business day. If your deadline has already passed, filing as soon as possible with a Reasonable Cause Letter gives you the best chance of penalty abatement. A 6-month extension is available with Form 7004 if filed before the original deadline.

Yes. Filing Form 7004 grants an automatic 6-month extension, moving the deadline to October 15. The extension must be filed before the original April 15 deadline. Note that this is an extension to file, not an extension to pay. Form 5472 itself does not have a tax payment component.

File the past-year Form 5472 and Pro Forma 1120 as soon as possible, along with a reasonable cause statement explaining the facts and circumstances and requesting penalty relief. The IRS processes late filings and decides case by case whether relief applies. Each additional unfiled year adds another penalty, so the exposure grows while the filing is outstanding.

A reasonable cause letter is a written argument submitted to the IRS alongside a late filing, requesting that the $25,000 penalty be waived. The IRS may grant relief if the failure was due to reasonable cause and not willful neglect. Whether it applies depends on the specific facts and circumstances of your case, and the decision is the IRS's alone: no preparer can promise an outcome. The letter is generated from a framework written by a practising U.S. CPA and structured to align with IRS reasonable cause standards. You select the situation that fits your case from a set of structured categories, and the system populates the letter with your filing details. It does not include an individual CPA review of your filing, and it is not tax advice. The result is included in your download alongside the completed forms.

Form 8832 is an entity classification election that changes how the IRS treats your LLC for tax purposes. By default, a single-member LLC is treated as a disregarded entity. If you want to be taxed as a C-Corporation instead, you file Form 8832 to elect that status. It is separate from the Form 5472 filing requirement, and electing C-Corporation treatment does not remove that requirement. People often ask about Form 2553, the S-Corporation election, at the same time. That one is not available here: an S corporation cannot have a nonresident alien as a shareholder, so an LLC owned by a non-U.S. individual cannot elect S status at all.

No, and this is a hard rule rather than a limitation of our service. An S corporation cannot have a nonresident alien as a shareholder, so an LLC owned by a non-U.S. individual cannot make the election at all. No preparer can file it for you. This is also why the S-corp advice you may have read elsewhere, which is usually written for U.S. owners, does not apply to you. If your circumstances have changed, for example you are now a U.S. resident or a U.S. person is joining the ownership, speak to a CPA about whether an S election has become available. Form 8832, electing C-Corporation treatment, is a different election and is open to you.
