EIN Application from Pakistan: 2026 Guide to Form SS-4 for Non-Resident Founders

An Employer Identification Number, or EIN, is a nine-digit federal tax identifier issued by the Internal Revenue Service to identify a business entity. For a Pakistani founder forming a US LLC or corporation, the EIN is the gateway to nearly everything else: opening a US business bank account, registering with payment processors such as Stripe and PayPal, listing on Amazon Seller Central or Etsy as a US seller, hiring contractors, filing federal returns, and meeting state-level licensing obligations. Without an EIN, a US entity exists on paper but cannot transact.

This guide covers the application process from Pakistan in 2026, with attention to the parts that catch non-resident founders out: the responsible party rule, the absence of online filing for non-residents, the choice between phone, fax and mail submission, the relationship between EIN and ITIN, and the documentation banks require once the EIN is in hand.

Who Needs an EIN

The IRS requires an EIN for every entity that has employees, that operates as a corporation or partnership, that is treated as a multi-member LLC, that withholds taxes on income paid to a non-resident alien, or that has Keogh or trust filings. Pakistani founders almost always fall into one or more of these categories the moment they form a US entity, even where the entity has no employees and no immediate revenue. A single-member LLC with a non-resident owner is a disregarded entity for income tax purposes but still needs an EIN for banking, contracting, and information reporting.

Beyond the formation context, EINs are required where the foreign entity is the withholding agent for US-source payments, where the entity is the payer or payee on a 1099 reporting form, or where the entity needs to register with FinCEN under the Beneficial Ownership Information rules. The practical rule is: if a US entity exists or is being formed, an EIN is needed.

The Form SS-4: What the IRS Asks

The application is made on Form SS-4, Application for Employer Identification Number. The current version is the December 2025 revision. The form runs to a single page but each line carries weight, and the responsible party rule introduced in 2014 has reshaped how non-resident applications are completed.

The opening lines establish the entity: legal name, trade name (if any), executor or administrator (for trusts and estates), mailing and business addresses, county and state of principal place of business. Lines 7a and 7b identify the responsible party. This is the natural person who, in IRS terms, ultimately owns or controls the entity, or exercises ultimate effective control over it. For a single-member LLC owned by a Pakistani founder, the responsible party is the founder. For a multi-member LLC, the IRS expects the principal owner to be named.

Line 7b asks for the responsible party's SSN or ITIN. Where the responsible party has neither (which is the typical Pakistani case), the IRS instructions permit the entry of "Foreign" in this field. This is a regularly missed point. Applications that leave 7b blank, or that enter a passport number, are routinely rejected. The correct entry is the literal word "Foreign" (or, where the founder already holds an ITIN, the ITIN itself).

Line 8a asks the entity type. For a Pakistani founder forming a Wyoming or Delaware LLC, the entry is usually "LLC" with the number of members specified at 8c. For corporations, the entries shift to "Corporation" with the relevant tax classification. Line 9a (reason for applying) is "Started new business" in the typical formation case. Line 10 (date business started) should match the formation date on the state filing. Line 11 (closing month of accounting year) is December for most LLCs and corporations defaulting to a calendar year.

The remainder of the form covers expected employees, agricultural employment, principal business activity, and so on. Most non-resident formation applications complete only the parts strictly relevant to the entity.

Why Pakistani Applicants Cannot File Online

The IRS's online EIN assistant is the fastest channel available for US-resident applicants, with EIN issuance during the same session. The system requires the responsible party to authenticate using a valid SSN or ITIN. Because Pakistani founders typically have neither at the point of forming a US entity, the online channel is unavailable to them.

Three offline channels remain available. The international phone line, the fax application, and the mail application. The choice between them is largely about speed.

EIN Application Routes for Non-Resident Founders

Pakistani founders cannot use the IRS online EIN application (which requires a US SSN or ITIN to authenticate). The three remaining channels differ significantly in speed and certainty. The table below summarises which channel suits which situation.

The International Phone Line: The Fastest Route

The IRS operates a dedicated phone line for international applicants at +1-267-941-1099 (this is not a toll-free number, and standard international call rates apply). The line is staffed Monday through Friday, 6:00 AM to 11:00 PM Eastern Time. From Pakistan, this corresponds to 4:00 PM to 9:00 AM the following day, Pakistan Standard Time, depending on the season. Callers should plan around the IRS's hours rather than Pakistan's.

The caller must complete Form SS-4 in advance and have it on hand. The IRS officer walks through the form line by line, asks clarifying questions on the responsible party and entity type, and issues the EIN at the end of the call. The EIN is provided verbally first; a written confirmation (the SS-4 letter, IRS Notice CP575) follows by mail to the address on the form. The verbal EIN is immediately usable for bank account opening and most other purposes.

The phone route is by far the fastest available channel for non-resident applicants. Where it works, it produces a working EIN within a single call. The route can fail where the responsible party's identity cannot be verified to the officer's satisfaction (for example, where the entity name on the SS-4 does not match the state filing record), in which case the application is bumped to fax or mail.

The Fax Application

For non-resident applicants who cannot or do not want to apply by phone, the fax route is the next-fastest option. The signed Form SS-4 is faxed to the international fax number published in the current IRS Instructions for Form SS-4 (the precise number changes occasionally; applicants should always work from the most recent Instructions rather than from older internet sources). The IRS processes fax applications and returns the EIN by fax to a return number on the application, typically within four weeks.

The fax route is the right choice where the founder is in a different time zone or schedule from the IRS phone line, where multiple entities are being applied for at once, or where the application has unusual elements that warrant a written rather than oral explanation. It is also the route used by professional service providers handling multiple non-resident filings in batch.

The Mail Application

The slowest channel is mail. The signed Form SS-4 is mailed to the address listed in the current IRS Instructions for international applicants, and the EIN is returned by mail in approximately four to six weeks. The mail route is rarely the right choice for a Pakistani founder unless the phone and fax routes have been exhausted, principally because international mail times alone can add another two to four weeks at each end.

EIN and ITIN: Two Different Numbers

Pakistani founders frequently confuse the EIN with the ITIN. The two are distinct. The EIN identifies the entity. The ITIN identifies the natural person on a US tax return where the person is not eligible for an SSN. A Pakistani founder forming a US LLC needs an EIN for the LLC. The same founder may also need an ITIN if the LLC is taxed as a partnership or S-corporation (where a Schedule K-1 will be issued in the founder's name) or if the founder is otherwise required to file a personal US return.

The sequence matters. The EIN is obtained first because it is needed to register the entity for banking and operations. The ITIN follows only when a US tax filing obligation crystallises. Filing for an ITIN before there is a tax filing reason will produce a rejection, because the IRS issues ITINs only where a Form W-7 is paired with a return or Exception category documentation.

For founders who will themselves be reported on a partnership return or distributing K-1, the ITIN application can be filed alongside the partnership return at year-end. For founders operating a single-member LLC (disregarded entity), no immediate ITIN is needed; only Form 5472 (the foreign-owned disregarded entity reporting form) and a pro forma Form 1120 are filed annually.

After the EIN: Banking and Compliance

The EIN unlocks a defined sequence of next steps. The first is opening a US business bank account. Most US banks now accept remote account opening for non-resident-owned LLCs through fintech-aligned providers (Mercury, Relay, Brex Cash among them) and some traditional banks (such as certain branches of Chase and Wells Fargo) where the founder visits in person. The bank typically requests the SS-4 confirmation letter (CP575), the state formation document, the operating agreement, the founder's passport, and proof of address. Some banks request a US business address, which can be a registered agent address rather than a leased premises.

The second is setting up payment processing. Stripe, PayPal, and Square all require the EIN, the bank account, and identity verification of the founder. Each platform has its own thresholds and ongoing reporting; the EIN appears on Form 1099-K reporting at year-end where transaction thresholds are met.

The third is FinCEN Beneficial Ownership Information (BOI) reporting, which applies to most US LLCs and corporations formed by non-residents. The BOI filing identifies the natural-person beneficial owners of the entity, including their addresses and identification documents. The filing is made directly with FinCEN through its online portal. As of 2026 the obligations and timelines have evolved with court rulings and Treasury guidance; founders should verify the current state of the rule before filing.

The fourth is annual federal and state filings. A foreign-owned single-member LLC files Form 5472 attached to a pro forma Form 1120 each year, even where there is no US-source income. A foreign-owned multi-member LLC files a partnership return on Form 1065 and issues K-1s to the members. Federal and state estimated tax obligations may also apply where the entity has US-source income.

Common Reasons EIN Applications Are Rejected

The most frequent rejection grounds we see on Pakistani non-resident applications are: line 7b left blank or filled with a passport number rather than the literal word "Foreign" or an ITIN; entity name on the SS-4 not matching the state formation record exactly; responsible party identified as the registered agent or the formation service rather than the actual founder; line 9a reason for applying selected as "Banking purpose" when the entity has just been formed (the correct entry is "Started new business"); and applications submitted before the state filing has cleared, with the result that the IRS cannot verify the entity's existence.

An additional issue specific to Pakistani founders is name transliteration. The Pakistani passport's transliteration of an Urdu name should match exactly the name used on the state filing and the operating agreement. Where the name has been recorded in slightly different ways across documents (different order of given names, different transliteration of vowels), the IRS will sometimes pause the application for verification.

A Word on How This Work Should Be Handled

An EIN application is a tax submission to the Internal Revenue Service governed by Treasury Regulation 301.6109-1, the SS-4 instructions, and the responsible party rule introduced in 2014. It is not a clerical task, and the offline channels available to Pakistani founders carry their own procedural rules. A wrongly entered responsible party can produce a rejection. A misaligned entity name between the state filing and the SS-4 can produce a rejection. A "Banking purpose" entry where "Started new business" is correct can produce a rejection. Each rejection adds weeks to the timeline at a moment when the founder is usually trying to coordinate banking, payment processing, and operational launch on a tight schedule.

For Pakistani founders the EIN sits at the centre of a wider compliance picture: state formation, EIN, ITIN where needed, BOI reporting, banking, payment processor onboarding, annual returns, and (where US activity grows) state-level tax registrations. Treating the EIN application in isolation leaves gaps that surface later as banking refusals, processor freezes, or IRS notices. A Pakistani founder who has watched a Stripe account suspended over a misaligned EIN-to-bank-account record knows the cost of these gaps personally.

LexForm prepares EIN applications as legal work and coordinates them with the broader formation and compliance picture. We complete Form SS-4 line by line, file via the international phone line where the founder's circumstances allow it (and via fax otherwise), pair the EIN issuance with operating agreement preparation, registered agent setup, BOI filing, and bank account introductions. Where the founder also needs an ITIN, we sequence the ITIN application after the EIN so that the W-7 is filed at the right point in the year. Our Wisconsin office handles the US-end relationships with banks, registered agents and tax preparers; our Islamabad office handles client-side documentation in Pakistan.

The first step is a short scoping call. We will confirm whether you need an EIN, an ITIN, or both, what state and entity type fits your activity, what the realistic timeline looks like, and how the EIN connects to the banking and operational steps that follow. There is no fee for the initial scoping.
