EIN for Peruvian LLC Owners: Complete 2026 Guide

If the phone line is busy, or you'd rather not do a live English-language interview, you can fax Form SS-4 to 855-215-1627 if faxing from within the US, or 304-707-9471 if faxing from Peru or anywhere else outside the US. Expect a 4 to 6 week turnaround for a faxed response with your assigned EIN. Mailing the SS-4 to the IRS's Cincinnati service center works too, but takes the same 4 to 6 weeks and adds international mail transit time on top, so it's rarely the better choice unless fax access is genuinely unavailable to you. Whichever method you pick, keep a copy of the submitted SS-4 and any confirmation number, since IRS staff will ask for these details if you ever need to request a replacement confirmation letter later.

The fastest route for a Peru-based founder is the IRS international phone line: 267-941-1099. This line is reserved for applicants without a US address, so as a Peruvian resident you're exactly who it's built for. It operates Monday through Friday, 6:00 AM to 11:00 PM Eastern Time, which lines up reasonably well with Peru's own time zone (Peru runs one hour behind US Eastern in standard time). Have your completed Form SS-4 in front of you before calling: legal LLC name, formation state, formation date, responsible party's full name and foreign passport number (no SSN or ITIN required), and the business purpose. Realistically budget 45 to 60 minutes for the full call, including hold time and the IRS agent walking through your SS-4 answers live - this is a real jump from the 20-30 minute estimate some older guides still repeat, so plan your morning or afternoon accordingly rather than squeezing it into a short break.

Peru's Controlled Foreign Company (CFC) regime is one of the more direct in Latin America: it applies to individual Peruvian taxpayers who personally own a foreign entity, not just to companies that route ownership through a domestic corporation. You are considered to control a CFC if you hold, directly or indirectly, more than 50% of the capital, profits, or voting rights of the foreign entity - which describes almost every single-member US LLC held by a Peruvian founder. The entity also has to sit in what Peru calls a low-taxation jurisdiction, defined by comparing the foreign entity's effective tax rate against Peru's own corporate rate. Because a single-member US LLC pays no US federal entity-level tax by default, it will typically fail this test and be treated as a CFC for Peruvian purposes.

Once your EIN is issued, the compliance clock starts, not stops. A foreign-owned single-member LLC that's disregarded for US tax purposes still has an annual filing obligation: a pro-forma Form 1120 paired with Form 5472, reporting reportable transactions between the LLC and its foreign owner (capital contributions, distributions, loans, and similar). This is an informational filing, not typically one that creates US tax liability if you have no US-source income - but missing it is expensive: the IRS penalty for a late or missing Form 5472 starts at $25,000 minimum, even when zero tax was actually owed. Mark this filing on your calendar the same day you get your EIN.

Before you start the process, gather: your LLC's Articles of Organization or Certificate of Formation from the state where you formed it; a completed Form SS-4 with every field filled in (not just the ones that feel relevant); your passport as identification for the responsible party field, since no US Social Security Number or ITIN is required for a foreign owner; a clear, one- or two-sentence description of what your business actually does, for the SS-4's business-purpose line; and a US mailing address, which can be your registered agent's address or a virtual mailbox service if you don't have one of your own. Having every field pre-filled before you dial in or send the fax cuts out the most common source of delay - an incomplete SS-4 that has to be corrected and resubmitted.

With an EIN in hand, Peruvian founders typically open a US business bank account remotely through Mercury or Relay, both of which currently accept Peru-based applicants without the account restrictions seen for some other countries. From there, EIN plus bank account unlocks Stripe, PayPal, and most US payment processors. Given the passive-income attribution question and the two-tier CFC nuance above, it's worth a short conversation with a Peru-based tax advisor about how your specific revenue mix (active services versus passive investment income sitting in the LLC) should be reported on your annual Peru return - the EIN process itself is straightforward, but getting the Peru-side classification right is the part worth getting a second opinion on.

Peru taxes resident individuals on worldwide income at progressive rates up to 30%, so many Peruvian founders look for a lean, liability-protected structure to bill international clients or run an e-commerce business - a US LLC fits that need well. It gives you a Delaware or Wyoming entity that US payment processors, Stripe, and marketplaces recognize instantly, plus personal liability separation from your Peru-based assets. But none of that works without an Employer Identification Number (EIN): you need it to open a US business bank account, register with Stripe or PayPal, and file the annual US tax paperwork your LLC is required to submit even with zero US-source income. This guide walks through exactly how the EIN process works for a Peruvian owner, plus the one Peru-side tax rule you actually need to understand before you file anything back home.

The most frequent errors: leaving line 7b of the SS-4 blank instead of writing "Foreign" or "N/A" for the SSN/ITIN field, which can bounce your application; using an outdated IRS fax number found in an old blog post; assuming you need the EIN before your LLC's formation is even approved by the state (you don't, but you do need the approved formation date on hand); and, on the Peru side, quietly assuming that because your LLC pays no US corporate tax, none of this matters back home - when in fact the CFC passive-income attribution rule means you may still owe Peruvian tax on interest or dividend-type income the LLC generates, even without ever transferring a sol to your Peru bank account.

The specific low-tax threshold under Peruvian CFC law is 75% of the applicable Peru income tax rate. With Peru's corporate rate at 29.5%, that works out to roughly 22.1% - any foreign jurisdiction taxing the entity below that line qualifies as low-tax for CFC purposes. Where Peru's rules give real relief compared to broader worldwide-income regimes is in what actually gets attributed: only the CFC's passive income - dividends, interest, royalties, rents, and gains from passive asset sales - is imputed to you annually regardless of whether you distributed it. Active business or services income earned through the LLC (consulting fees, product sales, SaaS revenue) generally is not swept into the CFC attribution mechanism, since it doesn't meet Peru's definition of passive income. SUNAT guidance issued in 2026 also clarified that when a CFC owns another foreign entity that is itself a CFC, the two entities' profits are not automatically consolidated - each layer's passive income has to be assessed independently, which matters if you ever add a holding-company layer above your operating LLC.
