Is there a US-Uruguay income tax treaty?

No comprehensive income tax treaty is in force, so relief from double taxation depends on Uruguay's domestic rules, not on a treaty article.

Can I form an LLC in New Mexico if I live in Uruguay and have never visited the US?

For a founder in Uruguay, yes. US LLC formation does not require US residency, a US visit or a Social Security Number. Founders based in Uruguay form New Mexico LLCs remotely using a registered agent for the required US address, and they apply for an EIN with "Foreign" or "N/A" in place of an SSN.

Can a Uruguayan resident open Mercury or Relay accounts?

Yes in principle. Uruguay is not on Mercury's prohibited list (residence-based) or Relay's (owners' citizenship/residency), subject to each bank's own review.

How long does a New Mexico LLC take from Uruguay?

For a founder in Uruguay, state approval in New Mexico typically takes a few business days to about two weeks depending on filing volume, and the EIN can often be obtained the same week by phone. Most founders have the LLC, the EIN and a bank application in 2-4 weeks.

What ongoing filings does a Uruguayan founder need for a New Mexico LLC?

For a founder in Uruguay, only the federal one: Form 5472 with a pro forma Form 1120, due every year for a foreign-owned single-member LLC, with a $25,000 minimum penalty if missed. New Mexico has no annual report or fee to add.

What time can I phone the IRS from Uruguay?

The IRS international line is open 6 a.m. to 11 p.m. Eastern. Uruguay stays on UTC-3, so the window is 7 a.m. to midnight in US daylight time and 8 a.m. to 1 a.m. in US standard time.

Does Uruguay tax income from a US LLC?

Historically Uruguay taxed mainly local-source income, but the 2026 reform (Law 20.446 with Resolution 1.517/2026) now taxes foreign income earned through non-resident entities at 12% when it falls outside the exemption regime. Get a current local opinion.

Why New Mexico

Why do Uruguayan founders look at New Mexico? Mostly because the state-level side is predictable. The filing fee is $50 ($50 online), the ongoing requirement is $0 ever — New Mexico is one of the only states with no ongoing annual report or annual fee for LLCs, and the state applies no tax on LLC income earned outside the state for non-resident owners. New Mexico does not publicly disclose member or manager names in its formation records. Keep in mind that the state says nothing about how Uruguay taxes you; that depends on Uruguay law and is covered further down this page. What New Mexico offers is the least ongoing paperwork of any of the five states.

For Uruguayan Founders

Uruguay has long been known for taxing mainly income earned inside its borders, which is why foreign-income structures attract attention there. Freelancers, software developers and online sellers in Uruguay form US LLCs to invoice in dollars and keep a US business bank account. The ground has shifted in 2026: a reform now reaches foreign income held through non-resident entities, so the old assumption that foreign-source income is simply outside the Uruguayan system should be re-tested before you form.

After Formation Checklist

Three things to do straight after formation. First, the paperwork: an Operating Agreement, and a note of the EIN letter's location (if it is lost, ask the IRS for Form 147C). Second, the money side: bank account, then Stripe or PayPal subject to their review. Third, the calendar: there is no New Mexico annual filing to calendar and the federal Form 5472 and pro forma 1120. Federal Beneficial Ownership Information reporting is not something you need to do: FinCEN's rule in force since August 14, 2026 permanently exempts all US-formed LLCs.

Is New Mexico Right For You

The case for New Mexico: minimizing ongoing paperwork is the top priority — no annual report, ever, is unique among these five states — and strict privacy matters more to you than name recognition. The case against is simply that another state may suit your priorities better, and changing states after formation means closing the LLC and starting a new one.

What Changed In Uruguay In 2026

The shift is from a system that largely left foreign-source income alone to one that now reaches foreign income earned through non-resident entities, at 12%, when it falls outside the exemption regime. Law 20.446 and Resolution 1.517/2026 are the texts to ask your adviser about, and the tax-holiday threshold of roughly USD 2 million is the figure that separates smaller structures from larger ones. Guidance written before 2026 should not be relied on without checking.

Forming In New Mexico Step By Step

For a Uruguay-based owner the order of operations is: registered agent first (you need their New Mexico address for the filing), then the Articles of Organization, then the EIN, then the bank account. The EIN application is Form SS-4; leave the SSN field as "Foreign" or "N/A". Calling the IRS international line (267-941-1099) is the fast route at about 45-60 minutes; faxing or mailing the form takes 4-6 weeks. Once you hold the EIN letter, bank and payment applications can begin.

Questions For Your Uruguayan Adviser

Ask your Uruguayan adviser three things before you form. Does your LLC fall within the exemption regime or the roughly USD 2 million tax holiday threshold, or does the 12% rate apply? How does Resolution 1.517/2026 define the non-resident entity and the income it covers? And how will US tax already paid be recognised? Because the reform is new, get the opinion in writing and date it.

New Mexico LLC For Uruguayan Founders

New Mexico means a $50 filing fee and no annual state report, which suits a Uruguayan owner who wants the US side to stay minimal while the 12% question under the new reform is settled.

Five Year State Cost Of A New Mexico LLC

Over five years, the state-level cost of a New Mexico LLC is a $50 filing fee and nothing recurring, so $50 in total, before the registered agent. That makes New Mexico the cheapest of the five states on this measure. The same arithmetic across the five states runs from $50 to $2,110. For a Uruguayan owner, the bigger variable is not this US state cost but whether the 2026 reform's 12% rate reaches your income.

What A New Mexico LLC Costs From Uruguay

Budgeting for a New Mexico LLC from Uruguay? The one-time state fee is $50 ($50 online). Every LLC then needs a registered agent (typically $100-150 a year); the EIN itself costs nothing when you apply to the IRS directly; and Mercury or Relay accounts are usually free. The yearly state-side item is $0 ever — New Mexico is one of the only states with no ongoing annual report or annual fee for LLCs. Bundled, EasyBrise Global Launch costs $295 for year one with a registered agent included and $149 a year to renew.

Your Recurring Dates As A Uruguayan Owner

As a Uruguayan owner, your recurring dates look like this. State: New Mexico adds no state annual filing at all. Federal: Form 5472 with the pro forma Form 1120 is due on the return due date, April 15 for a calendar-year LLC, extendable with Form 7004. For the one-off EIN call, the IRS line (6 a.m. to 11 p.m. Eastern) is open 7 a.m. to midnight Uruguayan time in US daylight time (8 a.m. to 1 a.m. in US standard time). Put the state date and the federal date in your calendar when the EIN arrives, because a missed Form 5472 carries a $25,000 minimum penalty.

Dual Citizenship And The Mercury Relay Rules

Mercury and Relay test eligibility differently, which matters if you hold more than one passport. Mercury's prohibited-countries list is based on country of residence, not citizenship, and a citizen of a listed country who lives elsewhere may still be eligible after review. Relay's list looks at the citizenship or residency of the owners. Uruguay is on neither list. If you hold another citizenship or live elsewhere, check that country against both lists before applying.

Uruguays 2026 Reform And The 12 Percent Rate

Under the 2026 reform (Law 20.446, with Resolution 1.517/2026), foreign income earned through non-resident entities that falls outside the exemption regime is taxed at 12%. The tax-holiday threshold in the regime was raised to roughly USD 2 million. In plain terms, a small LLC may sit inside the exemption or the holiday while a larger one does not, and the answer depends on the entity's income and your residency position. Because the rules are new, ask a Uruguayan adviser for a current opinion rather than relying on earlier guidance. On the US side the LLC files Form 5472 and a pro forma Form 1120 every year, with a $25,000 minimum penalty for a missed or incomplete filing.
