EIN for Saudi LLC Owners: The Question That Doesn't Apply, and the One That Does

This is the section worth reading carefully, because Zakat gets conflated with tax in ways that create real confusion for founders. Zakat exists in two entirely distinct forms in Saudi Arabia. The first is personal religious Zakat -- one of the five pillars of Islam, an individually observed obligation calculated on one's own qualifying wealth wherever it is held, including, in principle, an ownership interest in a foreign LLC. This form of Zakat is not administered, calculated, or enforced by any Saudi government authority; it is a private religious matter between the individual and their own conscience or religious guidance, and no filing obligation attaches to it. The second is mandatory business Zakat, administered by the Zakat, Tax and Customs Authority (ZATCA) under Ministerial Resolution No. 1007 and applicable to companies with Saudi or GCC ownership that hold a Saudi Commercial Registration. This mandatory Zakat is calculated on a business's Zakat base -- broadly, net equity plus long-term liabilities minus long-term assets -- at a standard 2.5% rate, filed annually with ZATCA within 120 days of the fiscal year end, and enforced with real penalties for non-compliance. Your US LLC, having no Saudi Commercial Registration and no legal existence as a Saudi entity, falls entirely outside this mandatory ZATCA regime, regardless of your own Saudi nationality or residency status. Founders sometimes assume that because they are Saudi, some version of mandatory Zakat filing must apply to their foreign business -- it generally does not, as long as the LLC itself remains a purely foreign, non-Saudi-registered entity.

Three things before you apply. First, your LLC needs state approval -- applying before formation is complete is a common, avoidable delay. Second, keep your Saudi national ID (Iqama for residents) or passport accessible in case the IRS requests identity verification during a fax or phone follow-up. Third, settle on a mailing address for the CP 575 confirmation letter -- a Saudi home address works, though many founders use a US virtual mailbox for faster, trackable delivery. Worth understanding early, given the section below: your personal Zakat obligation, if you observe it, is a religious matter you calculate yourself, entirely separate from any government filing tied to the LLC.

The application process itself does not vary by country. Saudi founders use the same three non-resident routes as everyone else, since the IRS's online EIN system requires an SSN, ITIN, or US legal residence most applicants do not have. Fax is the most reliable method: complete Form SS-4 and send it to 855-215-1627 if faxing from within the US, or 304-707-9471 from outside -- i.e., from Saudi Arabia -- with real-world turnaround commonly running one to two weeks despite the IRS's official four-business-day target. Phone, at 267-941-1099, is open to international applicants Monday through Friday, 6:00 AM to 11:00 PM US Eastern Time; Saudi Arabia runs seven to eight hours ahead of Eastern depending on daylight saving, leaving a workable window through the Saudi evening. Mail, at four to five weeks, is the slowest option and rarely worth choosing over fax.

A few fields on Form SS-4 consistently cause delays for non-resident applicants generally, Saudi founders included. Line 7b asks for the responsible party's SSN, ITIN, or EIN -- if you have none of these, the IRS's own instructions say to write Foreign or N/A, not leave the field blank, since a blank Line 7b is one of the most common reasons non-resident applications bounce back for correction. Lines 4a-4b need your full Saudi mailing address spelled out with Saudi Arabia written in full, since that is where your EIN confirmation letter, Form CP 575, will be mailed if you apply by post. Line 9a asks about entity classification -- accepting the default disregarded-entity status is standard for most single-member LLCs, and since Saudi Arabia has no personal income tax framework asking a comparable classification question, this election has no downstream Saudi tax consequence to weigh against.

Funding the LLC from Saudi Arabia is straightforward on the currency side. The Saudi riyal has been pegged to the US dollar at 3.75 riyals per dollar since 1986, one of the longest-standing currency pegs in the world, and the Saudi Central Bank imposes no meaningful exchange controls on individuals moving funds internationally for legitimate business purposes. There is no comprehensive US-Saudi Arabia income tax treaty, but this matters far less here than it does for founders in treaty-less countries with real home-country tax to offset -- since Saudi Arabia does not tax the income in the first place, there is no double-taxation problem for a treaty to solve. The absence of a treaty is a structural fact worth knowing, not a planning obstacle.

Once issued, your EIN arrives with a confirmation letter, Form CP 575, sent by fax, mail, or both depending on your application method -- keep it permanently, since banks and payment processors will ask for it during account opening. A lost CP 575 cannot be reissued, but the IRS will provide an EIN Verification Letter, Form 147C, as a substitute for any future banking or tax need. From here, most Saudi founders move on to opening a US bank account -- Mercury and Relay both work for Saudi-based founders, since Saudi Arabia is not on either provider's restricted list -- and, since almost every non-resident-owned single-member LLC counts as a foreign-owned disregarded entity, filing Form 5472 alongside a pro forma Form 1120 annually, regardless of whether the LLC had US activity that year. The $25,000 minimum penalty for missing that filing applies independently of anything ZATCA separately requires, and it remains the single most important recurring compliance obligation a Saudi founder actually needs to track.

If a formation service is handling your EIN application, confirm that the responsible party listed on Line 7a is you, the actual owner -- not a staff member at the formation company. The IRS defines the responsible party as whoever ultimately owns or controls the entity's funds and decisions, identified by their real name and passport-based nationality. An EIN record that lists someone other than the actual owner creates a mismatch that can complicate matters later if a bank or payment processor needs to verify beneficial ownership, which is the same information reported separately under BOI/FinCEN rules. If a provider suggests listing anyone but you, treat it as a red flag rather than a convenience, regardless of how routine it sounds.

Saudi Arabia occupies a genuinely simple position in this series for one straightforward reason: the Kingdom does not impose personal income tax on individuals, whether Saudi nationals or residents, and this applies regardless of where that income is earned. A Saudi founder who personally receives profits from a US single-member LLC is not filing a Saudi personal tax return on that income, calculating a foreign tax credit against it, or navigating a CFC-style attribution regime the way founders in most other countries covered in this series must. There is no personal income tax base for the profits to enter in the first place. This does not mean there is nothing at all worth understanding -- Saudi Arabia does apply Zakat, an entirely separate wealth-based obligation with its own rules, and getting clear on what Zakat actually covers, and what it does not, is where most of the genuine substance in this page lives. But on the pure income-tax question that dominates most of the other 29 pages in this series, the honest answer for Saudi Arabia is that the question largely does not arise. None of this changes what Form SS-4 asks for -- the IRS has no field for a founder's home-country tax regime -- but it does mean the planning energy that goes into CFC rules, remittance timing, and classification tests elsewhere in this series is better spent, for a Saudi founder, on the Zakat distinction covered below. This puts Saudi Arabia in a similar broad category to a couple of other genuinely simple pages in this series, but it reaches that simplicity through the most direct route possible: not a favorable exemption carved out of an otherwise complex system, but the outright absence of a personal income tax system to begin with.

A few mistakes show up repeatedly. Confusing personal religious Zakat, a private and unenforced obligation, with mandatory ZATCA business Zakat, which is a government-administered levy that only applies to Saudi-registered companies with Saudi or GCC ownership. Assuming a foreign, non-Saudi-registered US LLC has some Zakat filing obligation with ZATCA simply because its owner is Saudi, when the LLC's lack of a Saudi Commercial Registration keeps it outside that regime entirely. Assuming the absence of a US-Saudi tax treaty creates a planning problem, when Saudi Arabia's lack of personal income tax means there is no double taxation to relieve in the first place. Overlooking that adding a Saudi-registered entity to the structure later would bring ZATCA's Zakat rules, transfer pricing documentation, and holding-company registration requirements into play in a way that a purely personal LLC ownership never does. And, as with every non-resident applicant regardless of country, leaving Line 7b of Form SS-4 blank instead of writing Foreign, which remains one of the most frequent reasons the IRS returns a non-resident application for correction.

The picture changes if you later register a Saudi entity alongside your US LLC -- for instance, a Saudi company that holds an investment in the LLC, receives payments from it, or otherwise sits in the same structure. Once a Saudi-registered, Saudi or GCC-owned entity exists, ZATCA's mandatory Zakat rules apply to that entity's own Zakat base, and holdings like an investment in a foreign LLC can factor into that calculation depending on how it is structured and classified on the Saudi entity's balance sheet. ZATCA has also introduced specific holding-company registration procedures and, since 2024, transfer pricing documentation requirements for Zakat payers with controlled transactions, which would become relevant if payments flow between a Saudi holding entity and your US LLC. None of this affects a founder who simply owns the LLC personally with no Saudi entity in the structure -- it is a growth-stage consideration worth raising with a Saudi Zakat advisor specifically at the point you consider adding a local entity, not before. ZATCA has been actively modernizing enforcement across all of its regimes -- e-invoicing, VAT, and Zakat alike -- as part of the Kingdom's broader Vision 2030 tax administration push, so a founder who does eventually add a Saudi entity should expect a genuinely digital, well-documented compliance process rather than an informal one.
