Setting up a US LLC to run an ecommerce business has never been easier. Pick a state, pay the filing fee, grab an EIN from the IRS, open a bank account, and you’re ready to sell on Shopify, Amazon, or your own storefront. The whole process takes a few days, sometimes less.
But if you’re not American, there’s a compliance step after formation that most LLC services never mention. It’s called Form 5472, and it’s the single most expensive filing mistake a foreign ecommerce operator can make.
The filing nobody tells you about
Every US single-member LLC owned by a non-US person is required to file Form 5472 with the IRS annually. Not once. Every year, for as long as the LLC exists. It doesn’t matter if your store made $500,000 in revenue or $0. It doesn’t matter if you live in Germany, Thailand, or Argentina. If you’re not a US citizen or tax resident and you own a US LLC, this filing is yours to deal with.
Form 5472 is an information return. The IRS isn’t taxing you through it. What it does is report the financial transactions between you (the foreign owner) and your LLC. And the IRS uses a very broad definition of “transaction.” Funding your LLC’s bank account, paying yourself from it, covering business expenses, receiving a loan: all reportable.
The form gets filed alongside a pro-forma Form 1120, which is essentially a shell corporate tax return. Your LLC isn’t actually taxed as a corporation, but the IRS requires this return as a delivery vehicle for the 5472. It’s bureaucratic, it’s confusing, and it’s the kind of thing that falls through the cracks when you’re focused on running your store.
Why the penalty hits so hard
Here’s where it gets serious. The penalty for failing to file Form 5472, or filing it late, or filing it with missing information, is $25,000. Per form. Per year.
Read that again if you need to. If you formed your LLC three years ago to sell products on Amazon FBA and never filed, you’re looking at $75,000 in penalties. For an information return. Not a tax bill, a reporting form.
The IRS has been enforcing this aggressively. The penalty amount was increased from $10,000 to $25,000 specifically to close the compliance gap among foreign-owned LLCs, which have been growing fast in number thanks to the ease of online formation.
How this usually plays out for ecommerce operators
The typical scenario goes like this. You’re based outside the US and you decide to start an ecommerce business. Maybe it’s dropshipping, maybe it’s a private-label brand, maybe it’s a SaaS tool. You form a Wyoming or Delaware LLC because everyone in the forums and YouTube videos says that’s what you should do.
Formation goes smoothly. You get your registered agent, your EIN, your business bank account. Maybe you use Stripe Atlas, Doola, Firstbase, or a similar service. Everything feels handled.
Then a year passes. Maybe two or three. You’re busy growing revenue, optimizing ads, managing suppliers. Nobody sends you a reminder about Form 5472 because your formation service’s job ended when the LLC was created. Your bank doesn’t care. Your payment processor doesn’t care. And the IRS doesn’t send reminder notices. They send penalty notices.
The “no revenue” myth
One of the most common lies I hear is: “My LLC made no money this year, so I don’t need to file anything.”
Wrong. Form 5472 is required regardless of revenue. Even a dormant LLC with zero income needs to file if there were reportable transactions, and there almost always are. Did you put money into the LLC’s bank account? That’s a capital contribution. Did you pay the registered agent fee through the LLC? That’s a transaction. Did you pay for any business tool or subscription through the LLC? Reportable.
The only scenario where you might not need to file is if the LLC had literally zero financial activity for the entire year. No money in, no money out, no expenses paid. In practice, that almost never happens.
What to do if you’re already behind
If you’ve had a US LLC for one or more years and never filed Form 5472, here’s the practical path forward:
Don’t ignore it. The penalties accumulate. Every year you don’t file adds another $25,000 in potential liability. The sooner you file, the stronger your case for getting those penalties reduced or eliminated.
Gather your financial records. Pull your bank statements for each year you missed. You need to know every transaction between you and the LLC: contributions, distributions, expenses, loans. This is the data that goes on the form.
File delinquent returns with a reasonable cause statement. The IRS does grant penalty abatement when the taxpayer can demonstrate reasonable cause for the late filing. This isn’t as simple as writing “I didn’t know.” You need a well-structured explanation backed by documentation. Showing that you acted in good faith, corrected the issue as soon as you became aware, and had no prior history of non-compliance all help your case.
Get help if penalties are involved. If you’ve already received a penalty notice, or if you’re filing multiple years late, working with a Form 5472 specialist is the safest move. The reasonable cause argument needs to be specific to your situation, and the stakes are too high for guesswork.
Staying compliant going forward
Once you’re caught up, keeping compliant is straightforward:
Track your transactions throughout the year. Keep a simple log of every financial interaction between you and the LLC. This makes filing painless when the deadline arrives.
Mark April 15 in your calendar. Form 5472 is due on the same date as corporate tax returns, April 15 of the year following the tax year. You can request an extension to October 15, but the extension itself needs to be filed on time.
Don’t forget state requirements. Form 5472 is a federal filing, but your LLC may also have state-level obligations like annual reports, franchise taxes, or registered agent renewals. These vary by state and have their own deadlines.
Budget for it. Professional filing for Form 5472 typically runs between $100 and $500, depending on complexity. That’s a normal cost of running a US entity, and a lot cheaper than a $25,000 penalty.
So what’s the bottom line?
A US LLC is still one of the best structures for running an ecommerce business as a non-US operator. The banking access, the payment infrastructure, the credibility with American suppliers and customers: none of that changes. What changes is your awareness of what comes after formation.
The ecommerce space moves fast, and it’s easy to focus entirely on revenue and product development while compliance slides into the background. But the IRS doesn’t care how busy your Q4 was. The filing deadline arrives every year whether your store had its best month or its worst.
Now you know about Form 5472. File on time, keep your records clean, and your US LLC stays what it was meant to be.
