    EIN for Uruguayan LLC Owners: Complete 2026 Application Guide

    How Uruguayan founders get a US tax ID without a cédula, and what Uruguay's 2026 tax reform means for income from your US LLC

    Quick Summary

    Country
    Uruguay

    Fax and mail as slower alternatives

    Fax goes to 855-215-1627 from inside the US or 304-707-9471 from outside; mail routes through the Cincinnati service center. Both currently run roughly 4-6 weeks depending on IRS workload — useful as a backup, but the phone route saves you a month of waiting in almost every case.

    The phone application, step by step

    Have your LLC's formation documents on hand, then call the IRS International EIN line at 267-941-1099. It operates 6am-11pm US Eastern Time, and calling from Uruguay is fully expected — this line exists for exactly this situation. Budget 45-60 minutes for the full call including hold time. The agent will ask for your entity name, formation state and date, a one-line business purpose, and your name and Uruguayan address as the responsible party. You'll be given the EIN verbally before the call ends — write it down immediately, since the mailed confirmation letter takes weeks longer to arrive.

    What an EIN is and why you need one

    An EIN (Employer Identification Number) is the nine-digit federal tax ID the IRS assigns to your US LLC. Without it, you can't open a US business bank account, verify a Stripe or PayPal Business account, or file the annual paperwork the IRS requires of foreign-owned LLCs. It has nothing to do with your Uruguayan cédula de identidad — it identifies the company, not you.

    The exemption regime still on the table

    Uruguay's long-standing tax holiday lets new tax residents elect exemption from IRPF on foreign-source income for up to 11 years, though the 2026 reform raised the investment threshold to qualify (roughly $2 million in real estate, up from around $590,000) and removed the lower-presence 60-day pathway. If you already hold this exemption or qualify under it, your LLC's income may fall outside the new 12% rule — this is worth confirming with a Uruguayan tax advisor given how recently the regulations changed.

    Line 7b: what Uruguayan applicants write

    Form SS-4's Line 7b asks for the responsible party's SSN, ITIN, or EIN. As a foreign individual you have none of these, so you write "Foreign" or "N/A" — this is the standard, expected answer and won't slow your application down.

    Coordinating your US and Uruguayan filings

    Bring your EIN confirmation, LLC formation certificate, and a summary of what the LLC earned during the year to your Uruguayan accountant well before the DGI's filing window (June 29 to August 31, based on the last digit of your taxpayer ID). Given how new the 2026 foreign-income rules are, this is a year where getting professional input early matters more than in a typical year.

    What this means practically for your US LLC

    If you're a Uruguayan tax resident without the exemption, income you earn through your single-member US LLC — treated as passing directly to you for Uruguayan purposes much as it does for US purposes — is likely now subject to the 12% IRPF rate under the 2026 rules, with a foreign tax credit generally available for any US tax paid on the same income. The mechanics (payment schedule, withholding agent involvement) are still being finalized via DGI resolutions issued through mid-2026, so treat this as an evolving area to revisit with your accountant each filing period rather than a settled rule.

    The $25,000 filing requirement you can't skip

    Every foreign-owned single-member LLC must file Form 5472 alongside a pro forma Form 1120 annually, generally due April 15 (or October 15 with an extension). Missing this filing triggers a minimum $25,000 penalty regardless of whether the LLC made any profit — and you need the EIN before either form can be filed, which is why this isn't a step to defer.

    The IRS confirmation letter and what to do if it's lost

    You'll receive a CP 575 confirmation letter by mail a few weeks after your call. If it's misplaced, the IRS won't issue a replacement CP 575, but calling the same EIN line gets you a 147C verification letter instead — functionally identical for any bank or processor that asks to see it.

    Uruguay's 2026 tax reform and why it changes the calculus

    Budget Law 20.446, effective January 1, 2026, significantly broadened what foreign-source income Uruguay taxes for resident individuals. Before this reform, Uruguay's territorial system mainly reached foreign dividends and interest (taxed at 12% since 2011) while largely leaving other foreign income alone. The 2026 law extends that 12% tax to foreign capital gains, rental income, and — specifically relevant here — income received through non-resident entities, which under implementing Resolution 1.517/2026 (effective June 30, 2026) now captures income you earn through your US LLC if you're a Uruguayan tax resident outside the exemption regime.
