Your US LLC is useless until you have an EIN. No Stripe. No Mercury or Wise. No getting paid by US clients through proper channels. Without that nine-digit number, the LLC exists on paper and nothing else. You don't need a Social Security Number to get one. Not an ITIN either. As a founder based in Pakistan, you can get your EIN directly from the IRS through a process built for exactly this situation. This guide covers the whole thing, start to finish.
The EIN is what puts a founder in Lahore or Karachi on the same footing as someone sitting in a Delaware co-working space. The process is old-school - paper-based, fax-dependent - but it's precise. Get it right once and you're done.
Most people assume the EIN process is for US residents only. It isn't. Any non-US person who owns a US LLC can apply. No citizenship requirement. No residency requirement. No minimum time spent in the country.
| LLC Type | Foreign Owner Eligible? | SSN/ITIN Needed? |
|---|---|---|
| Single-Member LLC (1 owner) | ✓ Yes | ✗ No - passport ID is enough |
| Multi-Member LLC (2+ owners) | ✓ Yes | ✗ No - one responsible party needed |
The IRS gives foreign applicants three ways to apply for an EIN. For most Pakistani founders, one method is clearly better than the other two.
Faxing is the fastest method available to foreign applicants in 2026. Fill out Form SS-4, fax it to the IRS international line, and get your EIN faxed back within 4 business days.
The number is +1 304-707-9471. This is the IRS international fax line for applicants outside the US. Don't use domestic IRS fax numbers from older blog posts - those are for US residents and won't route correctly for foreign applications.
From Pakistan, you can send and receive faxes through online fax services like eFax or MyFax. Before signing up, check one thing: make sure the service supports the T.38 protocol. It's a more stable transmission standard for long-distance international faxes, and without it, failed or incomplete transmissions are a lot more likely.
One critical point most guides miss - don't use a one-way outgoing fax service. If your service can't receive incoming faxes, the IRS confirmation has nowhere to go. You need a service with a dedicated receive number.
The "Sign-and-Scan" rule: Print the SS-4, sign it with a physical pen, scan it, and send that version. The IRS has flagged forms with digital-only signatures as potentially invalid. A handwritten signature scanned as a PDF is the safest approach, full stop.
Faxing at 8:00 PM Pakistan time (10:00 AM Eastern) is a reliable window. It hits the IRS queue during active processing hours for the International Department instead of sitting overnight in a backlog.
Mail is slower - typically 4 to 6 weeks for foreign applicants - but it's a solid fallback if fax isn't working.
Send your completed Form SS-4 to:
The IRS mails back the CP 575 confirmation letter once your application is processed. That's the official document confirming your EIN - what you'll use to open bank accounts and register with payment processors. Don't lose it.
If your local postal service is unreliable for international correspondence, use a US-based registered agent or mail scanning service as your mailing address. The CP 575 is too important to risk on an uncertain delivery chain.
Phone is technically available, but for a Pakistani founder it means staying up until 2:00 AM PST to sit on hold for 45 minutes. The IRS international EIN line runs Monday through Friday, 6 AM to 11 PM Eastern Time - which translates to 3 PM to past midnight in Pakistan Standard Time.
If you do call, have Form SS-4 in front of you and answer the agent's questions verbally. Everything checks out, they assign an EIN on the call. It works, but the time zone makes this a last resort for most people here.
Most rejected EIN applications come down to the same handful of errors. Here's what to watch for.
Line 7b is the SSN or ITIN field. If you're a foreign owner without either, write "Foreign" in that box. That's it. This is the IRS-approved instruction, not a trick or a workaround.
Don't leave it blank - blank triggers a rejection or a request for more information. Don't write zeros or make up a number. Both are worse than leaving it blank. Just write "Foreign." That's the signal to the IRS processor that you're a non-resident applicant and the field doesn't apply to you.
This is the single most important line on the form for Pakistani founders.
Form SS-4 uses two separate address fields with different purposes.
This is where the IRS sends the CP 575 letter. Use your actual Pakistan address here - full street address in Lahore, Karachi, Islamabad, wherever you're based.
If local postal delivery is inconsistent, use a registered agent's address that offers mail scanning. A lost CP 575 is a completely avoidable problem.
If your LLC has a US registered agent, use that address here. It's your LLC's official US address on record.
No US address? Your Pakistan address works, but a registered agent address adds credibility to the filing.
Before you send your application, have these ready.
Your primary identification as a foreign applicant. You don't need to include a copy with the fax unless the IRS follows up, but keep it accessible.
RequiredDownload the current version from irs.gov. Fill every field. Line 7b says "Foreign." Sign with a real pen - digital signatures have been flagged as invalid.
RequiredProof the LLC exists. Have these available in case the IRS has follow-up questions about your entity.
Have ReadyFor the business address field on the form (Line 3). If applicable, use your registered agent's US address here for official filings.
If ApplicableBoth inbound and outbound capability are essential. Verify T.38 protocol support before signing up. Without incoming fax, you'll never receive the IRS response.
Required for Fax MethodRun through this checklist before faxing. Every item matters - a single missing piece can delay your EIN by days.
Getting your EIN is the first step. Once your foreign-owned LLC is active, the IRS has ongoing filing requirements that most new founders don't find out about until it's too late.
The most important one is Form 5472. Single-member LLCs owned by foreign individuals must file Form 5472 each year if there are any reportable transactions. That includes capital contributions, owner withdrawals, intercompany loans - basically any money moving between you and the LLC.
Form 5472 is filed alongside a pro forma Form 1120, which acts as a placeholder corporate return for the LLC. The penalty for missing this filing starts at $25,000 per violation. That's not a typo. It's one of the steeper IRS penalties in the foreign-owned entity space, and it applies even if the LLC had minimal or no income.
The penalty for missing the Form 5472 filing starts at $25,000 per violation. That's not a typo. It's one of the steeper IRS penalties in the foreign-owned entity space, and it applies even if the LLC had minimal or no income.
This guide covers the EIN step specifically. Form 5472 is a separate annual obligation. If you're unsure about your compliance requirements, speak with a US tax professional who works with foreign-owned entities before you start moving money in or out.
You now know exactly how the process works. We handle the paperwork, the fax, and the follow-up - so your EIN arrives correctly the first time. No rejections. No delays.
No. An ITIN and an EIN are completely separate tax IDs for different purposes. An ITIN is for individuals filing US personal tax returns - your LLC doesn't need that. Writing "Foreign" on Line 7b of Form SS-4 is the only step required for foreign owners.
No, you can't. The IRS online EIN application is only available to applicants with a valid SSN or ITIN. Without one, the online portal won't let you complete the process. Your options are fax (fastest), mail (slowest), or phone - which, from Pakistan, means a very late night.
Typically 4 business days. The IRS faxes the EIN back to the same receive number you sent from, which is why your fax service must support incoming faxes. If you have downstream deadlines like a bank account opening, build in a full week as a buffer.
Nothing. Applying directly through the IRS is free. Third-party services that handle the application for you do charge a fee - and they can be worth it if you'd rather not deal with the process yourself - but the IRS charges nothing.
Some do offer EIN filing as an add-on service, yes. If you go that route, make sure the person listed as Responsible Party on the SS-4 is a real individual, not the registered agent company itself. An entity listed as Responsible Party is grounds for rejection.
Section 9 of the form lets you name a Third-Party Designee - someone in the US or elsewhere who's authorized to receive the EIN and discuss the application with the IRS on your behalf. If you have a trusted contact in the US, this can sometimes speed up delivery and cut out international mailing delays entirely.
Everything you need to go from zero to EIN - in order, without missing a step.
Check your receive inbox first. No response at all? Send again. International fax lines occasionally drop transmissions. If fax keeps failing, switch to the mail method.
Don't risk a $25,000 compliance error on Form 5472 by figuring it out after the fact. If you want someone to handle both the EIN setup and the 5472 filing properly, an EIN service that covers foreign-owned LLCs is worth every cent.
You have everything you need. Form SS-4, Line 7b, fax number, timing. We handle the full process for Pakistani founders - correctly, the first time - so you can get on with building.
