EIN for Dominican LLC Owners: Complete 2026 Guide

With an EIN in hand, Mercury and Relay both currently accept Dominican Republic-based applicants for remote US business bank account opening. From there, EIN plus bank account unlocks Stripe, PayPal, and most US payment processors for a Dominican-owned LLC. Given how recently Law 30-26 changed the definition of taxable foreign income, it's worth a fresh conversation with a Dominican tax advisor about how your specific LLC income - distributions, financial gains, or technical services fees - is classified under the new rules.

The most common issues: leaving line 7b of the SS-4 blank instead of writing 'Foreign' or 'N/A' for the SSN/ITIN field; assuming the Dominican Republic's traditionally territorial-leaning approach to foreign income still applies unchanged after Law 30-26's July 2026 expansion; and using an outdated IRS fax number pulled from an old article.

Before applying, gather: your LLC's Articles of Organization or Certificate of Formation, a fully completed Form SS-4 addressing every applicable field, your passport to identify the responsible party (no SSN or ITIN required), a US mailing address (a registered agent or virtual mailbox works fine), and a short description of what the business does. An incomplete SS-4 remains the most common reason applications get sent back for correction.

If a live call doesn't fit your schedule, fax your completed SS-4 to 304-707-9471 (the line for applicants outside the US) and expect your EIN confirmation in 4 to 6 weeks. Mail to the IRS's Cincinnati processing center is also available but adds international transit time on top of the same 4-6 week window, making it the slowest realistic option.

The fastest EIN route from the Dominican Republic is the IRS's international applicant line, 267-941-1099, open Monday through Friday, 6:00 AM to 11:00 PM Eastern Time - which lines up closely with the Dominican Republic's own time zone, one of the more convenient calling windows in this guide series. Have your completed Form SS-4 ready before calling: LLC legal name, formation state and date, responsible party's name and passport number (no US SSN or ITIN needed), and a short business-purpose description. Budget 45 to 60 minutes for the full call including hold time and the live SS-4 walkthrough with the IRS agent.

Once your EIN is issued, a foreign-owned single-member LLC that's disregarded for US federal tax purposes must file an annual pro-forma Form 1120 together with Form 5472, disclosing transactions between the LLC and its Dominican owner - capital contributions, distributions, and intercompany loans included. This is purely informational when there's no US-source income, but the penalty for a missed or late Form 5472 starts at $25,000 minimum, regardless of whether any actual US tax was due.

The Dominican Republic has no controlled foreign company legislation - there's no rule requiring a Dominican resident to currently include a foreign entity's undistributed profits in their taxable income the way classic CFC regimes elsewhere in this guide series do. The traditional tax event for foreign business income has simply been whatever you actually bring into the country or receive as a distribution, not what the foreign entity retains.

The same reform raises the standard corporate income tax rate structure (a temporary 30% band for the largest companies through 2028, with the general rate remaining 27%), introduces a new 15% withholding tax on cross-border payments for software licenses, online advertising, and data storage or hosting services, and updates personal income tax brackets effective 2027 with a higher tax-exempt threshold and a new top 27% bracket. None of these directly change the CFC picture, but they reshape the broader compliance environment a Dominican founder with international income now operates in.

That relatively simple picture is part of why a US LLC appeals to Dominican founders selling internationally, running a SaaS product, or freelancing for US clients - a widely recognized entity type paired with a home tax system that historically didn't reach undistributed foreign profits. But the LLC only becomes functional once it has an Employer Identification Number (EIN): without one, you can't open a US bank account, can't onboard Stripe or PayPal, and can't file the annual US paperwork the LLC owes regardless of US-source income.

Here's what's genuinely new: Law 30-26, enacted in June 2026, explicitly broadens what counts as taxable foreign-source income for individuals, adding investments, financial gains, and technical assistance services to the categories now covered, effective July 2026, described in official guidance as a broad and illustrative definition. This is a meaningful shift from a system that had leaned more territorial in practice for individuals - a Dominican founder receiving distributions from a US LLC, or providing technical/consulting services billed internationally, should treat this as a live question worth confirming with a Dominican tax advisor rather than assuming the old, narrower picture still applies.
