Form 5472 for E-Commerce Founders: Complete 2026 Guide

The obligation has nothing to do with which marketplace you use. It depends on two facts: a foreign person owns at least 25% of the US LLC, and the LLC had a reportable transaction with that owner or a related party. Because forming and funding an LLC always moves money from the owner, virtually every foreign-owned single-member LLC has a reportable transaction in its first year, so almost all must file. Read the core obligation on Form 5472 for foreign-owned single-member LLCs.

E-commerce is simply the largest umbrella of founders this hits. A non-resident who opens a Wyoming or New Mexico LLC to sell on Amazon, then wires in startup capital and pays for inventory, has already triggered the requirement before the first sale. The form reports the owner-to-LLC money flow, not the customer-to-LLC revenue.

Founders often assume Amazon FBA is different from a Shopify dropshipping store, or that an Etsy shop is too small to count. The IRS does not look at the storefront. It looks at the entity. If the legal owner of the LLC is a non-US person, the same Form 5472 rule applies across every channel below.

The constant across all five rows is the entity. Whatever you sell and wherever you list it, a foreign-owned single-member LLC reports its owner transactions on Form 5472.

This is the most misunderstood point for e-commerce founders. Your Shopify or Stripe payouts from customers are not what triggers Form 5472. The reportable items are transactions between the LLC and the people who own or are related to it. The most common ones for an online store are below.

Because nearly every store starts with the owner funding it, you are almost always a filer from day one. See how this maps onto the return on the pro forma 1120 page.

A single-member LLC is “disregarded” for tax purposes, meaning the IRS normally looks straight through it to the owner. But for information reporting, final regulations under T.D. 9796 treat a foreign-owned disregarded entity as a corporation for tax years beginning on or after January 1, 2017. That is the disregarded-entity-as-corporation rule. It does not make your store a corporation for tax — it only creates the duty to file Form 5472.

Because the LLC has no real corporate return, you complete a pro forma(skeleton) Form 1120: you fill in the name, address, and EIN at the top, write “Foreign-owned U.S. DE” across the top, and staple Form 5472 to it. No corporate tax is calculated. See pro forma 1120 for a walkthrough.

The deadline is the 15th day of the 4th month after the tax year ends — April 15 for a calendar-year LLC, which describes nearly every e-commerce store. The six-month extension via Form 7004 only extends filing; a disregarded entity has no tax to pay with it, so there is no balance to estimate. Mark the date early, because the proof of timely filing is what protects you from the penalty.

There is no e-file path for a foreign-owned disregarded entity, which surprises founders used to filing everything online. The only two accepted methods are mail and fax, and the filing must be sent by the deadline. From overseas, fax is usually the faster, more verifiable choice because you keep an instant transmission confirmation.

If mailing and faxing from another country sounds risky, we handle the whole filing for you. Start on the apply page.

Form 5472 carries one of the harshest information-return penalties in the tax code, and e-commerce founders are frequent targets because so many open LLCs without realizing the duty exists. Because there is no statute of limitations on an unfiled information return, a year you missed years ago can still be assessed today, and the per-form structure means three forgotten years equals $75,000 before any continuation penalty.

We do not provide penalty-abatement or IRS representation. The reliable fix is to file correctly and on time. Compare the cost of doing that against the penalty on the pricing page.

For a while, founders worried about stacking a FinCEN beneficial ownership information (BOI) report on top of Form 5472. Under the March 2025 interim final rule, a US-formed LLC — even one owned entirely by a non-US person — is exempt from BOI reporting. Only entities formed abroad and registered to do business in the US (foreign reporting companies) file BOI.

That exemption does not touch Form 5472. The two are completely separate obligations under different laws. Your foreign-owned single-member LLC still files Form 5472 with a pro forma 1120 every year. We handle that filing for a flat $299 on the apply page.
