A Registered Agent Won’t Get You an EIN. Here’s Who Actually Does.

Three different jobs get sold to non-resident founders as one bundle, and untangling them before you sign up saves a lot of confused emails later.

Every few weeks, somewhere on a forum for people setting up US companies from abroad, the same question shows up in a slightly different outfit: is there one service that just handles everything — the LLC paperwork, the EIN, the ongoing IRS filings — so a founder outside the US doesn’t have to juggle five vendors and five time zones. It’s a completely reasonable thing to want. You’re not in the country. You can’t walk into an IRS office. You’d rather pay one invoice than track four.

But here’s the part that trips people up: the words “registered agent” sound like they mean “the company that handles my US business stuff,” and legally they mean something much smaller.

What a registered agent is actually required to do

Every US state that lets you form an LLC requires you to name a registered agent — someone with a physical street address in that state who can be reached during business hours to accept official mail and legal notices on the company’s behalf. That’s the job, defined by statute, not by marketing copy. If your LLC gets sued, or the state sends a compliance notice, the registered agent is the one who has to be sitting there to receive it. It’s an address-and-mailbox function with legal teeth, and non-residents need it because they don’t have a US address to put on file themselves.

Notice what’s missing from that description. Nothing about the IRS. Nothing about tax forms. A registered agent’s statutory job ends at “receive the mail and forward it.” Getting a company an EIN is a completely separate process, run by a completely different federal agency, with its own rules — and for non-residents specifically, those rules get more complicated, not less.

Why the EIN part is where things actually get hard

The IRS’s online EIN application is fast, but it isn’t available to everyone. It requires the “responsible party” listed on the application to already have a Social Security Number, an ITIN, or an existing EIN. Founders who have none of those — which describes a lot of non-resident owners — can’t use the online tool at all. The route that’s left is Form SS-4, filed by fax, by mail, or by phone through the IRS’s line for applicants with no US address, none of which move at online speed.

There’s also a detail buried in that form that matters more than it looks: a “third party designee” section, where you can authorize someone else to submit the application and field the IRS’s follow-up questions on your behalf. That designee’s phone number is what the IRS calls if anything on the form needs clarifying. So the useful question to ask a provider isn’t “do you help with EINs” — almost everyone will say yes to that. It’s who is actually listed as the designee, and whether that’s a real person who picks up an international-looking call and knows the file, or a name on a checkbox that gets forwarded to a template.

And then there’s the part after the EIN arrives

Getting the number is a milestone, not a finish line. A single-member LLC owned by a non-resident is typically treated as a disregarded entity that has to file Form 5472 every year, alongside a pro forma Form 1120, just to report transactions between the company and its foreign owner. This isn’t a formality to skip — the penalty most CPAs cite for a missed or incomplete filing starts at $25,000, which is a serious number for a company that might not have made a dollar in revenue yet. That filing sits closer to tax preparation than to anything a registered agent’s license covers.

So the honest way to think about “one company handling everything” isn’t whether it’s possible — plenty of providers now stack these services together, and that can genuinely save you the headache of managing five relationships. It’s whether you can see, for each of those three jobs, who’s actually doing the work and putting their name on it. A registered agent, an EIN filer, and a compliance preparer can absolutely live under one roof. They just don’t automatically come as one person doing one thing.

Questions Founders Keep Asking Me

Does a registered agent automatically apply for my EIN? No. A registered agent’s legal role is limited to receiving official mail and legal notices at a US address in the state of formation. Getting an EIN is a separate step with the IRS, and some registered agent companies offer it as an add-on — but that’s a business choice on their part, not something the role requires.

Can I get an EIN without a Social Security Number? Yes, but not through the fast online tool, which requires the responsible party to already have an SSN, ITIN, or EIN. Without one, the application goes through Form SS-4 by fax, mail, or the IRS’s international phone line, and it takes noticeably longer than the instant online version.

Once I have an EIN, am I done with IRS paperwork? Usually not, if the LLC is foreign-owned. There’s typically an annual Form 5472 filing (with a pro forma Form 1120) required to report transactions between the company and its owner, and missing it can trigger a penalty that starts at $25,000. It’s worth confirming this with a CPA as soon as the EIN comes through, not a year later.

Not legal or tax advice — confirm with a CPA.
