EIN for Israeli LLC Owners: Complete 2026 Application Guide

If you fax Form SS-4, use 855-215-1627 from within the US or 304-707-9471 from outside. Mail goes to the Cincinnati service center. Both fax and mail currently run roughly 4-6 weeks depending on IRS processing workload at the time — this window has been longer in some periods and shorter in others, so don't bank on a specific date. The phone route remains dramatically faster for almost everyone, and is worth the international call cost.

Call the IRS International EIN line at 267-941-1099 (not toll-free — factor in the call cost from Israel, or use a VOIP service). It operates 6am-11pm US Eastern Time, and being outside the US does not disqualify you — this line exists specifically for international applicants who can't use the SSN-gated online tool. Expect the full call, hold time included, to run 45-60 minutes. This remains the fastest of the three official methods by a wide margin.

Without an EIN, your LLC exists on paper in your state's records but can't function as a business. Banks like Mercury and Relay won't open an account for it. Stripe and PayPal Business won't verify it. The IRS won't accept any tax filing tied to it, including the annual Form 5472 that foreign-owned LLCs must file. In practice, the EIN is the single document that turns a formation certificate into a working company — most founders treat it as step two, right after incorporation, rather than something to delay.

Line 7b on Form SS-4 asks for the responsible party's SSN, ITIN, or EIN. As a foreign owner with none of these, you write "Foreign" or "N/A" — this is the standard, expected answer and does not delay or block your application. Some applicants worry that leaving this blank looks incomplete; it doesn't, as long as you write the word rather than leaving the field empty.

An LLC with foreign ownership that fails to file Form 5472 alongside a pro forma Form 1120 faces a minimum $25,000 penalty per missed filing year — and neither form can be filed without an EIN, so this isn't optional paperwork you can defer. The filing deadline is generally April 15 (or the extended October 15 deadline if you file for an extension), and the penalty applies even to LLCs with zero income, since the requirement is about disclosure of foreign ownership, not profitability.

If you have formed a US LLC as an Israeli resident, the IRS will not process your bank account application, file your annual return, or let you claim tax treaty relief until you have an Employer Identification Number (EIN). The good news: EIN issuance has nothing to do with your Social Security Number, your Israeli Teudat Zehut, or your immigration status. It is a nine-digit US federal tax ID issued to the business entity itself, not to you personally — which is why the process works the same whether you're a first-time founder in Tel Aviv or someone who has run three companies before.

The most frequent error is leaving the responsible party's foreign address incomplete or inconsistent with the formation documents — the IRS cross-checks this against your Articles of Organization, and a mismatch can trigger a follow-up letter that delays everything by weeks. The second common mistake is assuming a passport number goes on Line 7b instead of "Foreign." Third, some founders call before their LLC is officially formed with the state — the IRS wants your formation date and state to already exist, so calling a day too early means calling again. Fourth, a number of founders lose their CP 575 in the weeks between the call and actually opening a bank account, then scramble when Mercury asks for it — requesting the 147C proactively once you know the letter is delayed saves this step.

You'll receive an EIN confirmation letter (CP 575) by mail, typically arriving a few weeks after your phone call. Keep the original somewhere safe — banks and payment processors will ask to see it during account opening. If it's lost, the IRS will not issue a replacement CP 575 under any circumstances, but you can call the same EIN line and request an EIN Verification Letter (147C) instead, which every bank, processor, and government agency accepts as a full substitute.

Once you have the EIN in hand — whether verbally from the phone call or via the mailed CP 575 — the next practical steps are: open your US business bank account (Mercury or Relay both work well for non-resident founders), set up your payment processor if you're taking customer payments, and calendar your Form 5472/1120 deadline so it doesn't sneak up on you eleven months from now. Most Israeli founders handle these three in the same week they get the EIN, while the formation process is still fresh.

First, have your LLC's formation documents and EIN application (Form SS-4) filled out before you dial — the agent will read questions from it in order, and having answers ready cuts the call short. Second, call 267-941-1099 during US Eastern business hours (6am-11pm) — calling early in that window (roughly 6-9am Eastern, afternoon/evening in Israel) tends to mean shorter hold times. Third, when connected, you'll confirm the entity name, formation state, formation date, business purpose (a one-line description like 'consulting services' or 'software development' is enough), and the responsible party's name and foreign address. Fourth, the agent assigns the EIN verbally on the same call — write it down immediately, since the mailed confirmation letter can take several weeks to arrive. The full call, including hold time, typically runs 45-60 minutes.

Israeli tax residents who own a foreign LLC sometimes elect under Section 75B of the Income Tax Ordinance to treat that LLC as tax-transparent for Israeli purposes — meaning the LLC's income and expenses flow directly onto your personal Israeli return, similar in spirit to how the IRS already treats a single-member LLC as a disregarded entity for US purposes. This election is entirely separate from getting your EIN. Your EIN application proceeds the same way regardless of how you plan to elect for Israeli tax purposes — but it's worth knowing the election exists before your accountant raises it, since the two filings intersect on your Israeli tax return and getting the sequencing wrong (electing late, or not documenting the US entity correctly) can complicate an otherwise straightforward filing.

Bring your EIN confirmation, LLC formation documents, and a summary of what the LLC earned during the year to whoever files your Israeli return. They'll need all three to properly document the transparency election if you choose to make one, and timing the election correctly from your first tax year avoids a messier retroactive filing later. If you're unsure whether the 75B election benefits your specific situation, this is a conversation worth having before your first Israeli filing deadline rather than after.

The United States and Israel have had an income tax treaty in force since 1975, and while a single-member LLC's default disregarded-entity status can complicate treaty claims (the treaty was written with corporations in mind, not pass-through entities), your EIN is still the identifying number the IRS uses on any treaty-related filing, including Form W-8BEN or W-8BEN-E if a US client or platform asks you to certify your foreign status. Whether treaty benefits apply to your specific structure depends on how your LLC is classified and what income it earns — a question worth raising with your accountant rather than assuming either way.
