Forming a US LLC from Brazil: Complete Guide (2026)

Brazil has no income tax treaty with the United States. It is one of the largest economies in the world without one. Receita Federal (the Brazilian IRS) taxes worldwide income at progressive rates up to 27.5%, and there is no treaty-based relief, no reduced withholding, and no tie-breaker rule for residency disputes. Every dollar the US LLC earns is reportable in Brazil.

Most formation guides gloss over this. Firstbase has a São Paulo office. Over 1,500 Brazilian tech startups raised funding in 2024-2025. The appetite for US entities is real. But the structural gap between "forming a US LLC" and "operating one compliantly from Brazil" is wider than most founders expect.

I have operated US entities since 2007 and have watched this exact gap catch founders who assumed the US LLC would be "tax-free" because it is a disregarded entity. A disregarded entity in the US does not mean disregarded in Brazil. Receita Federal treats the income as the founder's personal worldwide income and taxes it at Brazilian rates.

This guide covers the full formation process and the compliance layers that apply specifically to Brazilian residents.

Step 1: Choose a State

Three states dominate for non-resident LLC formation. The differences are real but narrower than formation services suggest.

For most Brazilian solo founders, Wyoming is the practical choice. Low fees, no member disclosure, no state income tax. It just works.

Delaware makes sense if you are raising venture capital. US investors and their lawyers expect Delaware law, and the Court of Chancery has the deepest body of corporate case law. For a solo founder running SaaS or freelance work, that infrastructure adds cost without benefit.

New Mexico is the cheapest option at $50 one-time with no annual reports. The trade-off: less established case law and fewer formation services with NM-specific expertise.

No US state restricts LLC formation by nationality. All three accept Brazilian citizens on the same terms as any other non-resident. The full state comparison for non-resident LLCs also covers Nevada and other states where the marketing does not match the structural reality.

Step 2: Form the LLC

Three components:

1. Registered agent — A US-based person or company that receives legal documents on behalf of the LLC. Required in every state. $50-$300/year. More on registered agents.

2. Articles of Organization — Filed with the state. Lists the LLC name, registered agent, and basic structure. Most states process in 1-5 business days.

3. Operating Agreement — Not filed with the state but legally significant. Defines ownership, management, and profit distribution. Single-member LLCs should have one to establish separation between personal and business assets.

A note on the CPF: Your Cadastro de Pessoa Fisica is Brazil's national taxpayer ID, issued by Receita Federal. US LLC formation does not require it. But the CPF is central to Brazilian tax reporting. When you report the US LLC's income on your IRPF, the CPF links the foreign entity's income to your tax file. Every Brazilian resident already has one.

Formation services handle the entire US process for $200-$500. Full cost breakdown.

Step 3: Get an EIN

The EIN is the LLC's US tax ID. You need it for banking, tax filing, and payment processor setup.

Brazilian nationals can get an EIN without an SSN or ITIN. Full EIN guide.

The fax method from Brazil:

1. Download Form SS-4 from IRS.gov
2. On Line 7b (SSN/ITIN of responsible party): write "Foreign"
3. Fax to +1-855-215-1627 (international applicants) or +1-855-641-6935 (domestic)
4. IRS returns the EIN by fax within approximately 4 business days

Timezone note: Brasilia Time is UTC-3. During US standard time (Nov-Mar), BRT is ET+2. During daylight saving (Mar-Nov), BRT is ET+1. The IRS international line operates Mon-Fri 6 AM-11 PM Eastern at (267) 941-1099. Calling early from São Paulo catches the IRS before hold times build up.

The online EIN application does not work without an SSN. Mail submission takes 4-6 weeks. Fax or phone is far faster.

Step 4: Open a US Bank Account

Brazilian nationals face no country-specific restrictions for US banking. Brazil is not on any sanctions list. OFAC screening applies to all non-resident applicants equally, and Brazilian citizens go through standard due diligence, not enhanced country-based screening.

Wise deserves special mention for Brazilian founders. Wise operates extensively in Brazil, holds a Banco Central do Brasil license, and offers BRL local accounts. You can hold both USD (for the LLC) and BRL (for Brazilian operations) in the same platform with competitive conversion rates. This does not replace a dedicated US business bank account like Mercury or Relay, but it makes cross-border transfers between Brazil and the US much simpler. For a full walkthrough of BRL-USD banking options, see the US banking guide for Brazilian founders.

Step 5: Payment Processing

Brazilian founders have more payment processing options than most non-resident LLC owners because Stripe operates both in Brazil and via US entities.

The split is straightforward. Selling to US or global customers? Process through Stripe US via the LLC. Selling to Brazilian customers? Use Stripe Brazil, Pagar.me, or MercadoPago via a CNPJ. Many founders who serve both markets run both: a US LLC for international revenue, a Brazilian LTDA or MEI for domestic.

The Compliance Layers

Everything above is mechanical. Formation services handle it. What follows is where the real risk sits for Brazilian founders.

Receita Federal: Worldwide Income Taxation

Brazil taxes worldwide income of its tax residents. This is the single most important fact for a Brazilian founder operating a US LLC. For a deeper look at how Receita Federal treats US LLCs in the absence of a tax treaty, see the Receita Federal compliance guide for Brazilian LLC founders.

A US single-member LLC is a disregarded entity for US federal tax purposes. The IRS treats its income as the owner's personal income. Receita Federal does the same thing, but for the opposite reason: it does not recognize the US LLC as a separate taxable entity, so the income flows through to the Brazilian resident's IRPF (Imposto de Renda Pessoa Fisica, individual income tax).

Progressive tax rates (2026 IRPF):

At current exchange rates (roughly R$5.0-5.5 per USD), a US LLC generating $2,000/month in profit already exceeds the 27.5% bracket. The marginal rate hits fast for any meaningful LLC income.

The "disregarded entity" trap: Many Brazilian founders hear that a US LLC is "tax-free" because it is a pass-through entity. For US federal income tax, that can be true if the LLC has no US-source income. But "no US tax" does not mean "no tax." Receita Federal treats the same income as the founder's personal worldwide income and applies Brazilian rates.

No US-Brazil Tax Treaty

This gap separates Brazil from most other major economies in practice:

• No reduced withholding rates. If the US LLC receives income subject to US withholding (dividends, certain royalties), the default 30% rate applies. Treaty countries typically negotiate 10-15%.

• No tie-breaker rules. Without a treaty, both countries can assert full taxing rights simultaneously when a founder qualifies as a tax resident of both.

• No mutual agreement procedure. Each country's tax authority operates independently. There is no mechanism to resolve disputes between them.

• Foreign tax credit exists, but with limits. Brazil allows a credit for taxes paid to foreign governments under reciprocity principles (Article 26 of Law 9.249/1995). The credit cannot exceed the Brazilian tax attributable to the foreign income, and it requires documentation that the foreign tax was actually paid.

India, China, the UK, Germany, Canada, Australia, Japan, and South Korea all have income tax treaties with the US. Brazil does not. Brazilian founders face structurally higher cross-border tax friction than founders from nearly every other major economy.

BACEN: Declaração de Capitais Brasileiros no Exterior (CBE)

BACEN (Banco Central do Brasil) requires Brazilian residents to report foreign assets through the CBE.

Foreign assets for CBE purposes include: US LLC ownership interest (at fair market value), US bank balances, Wise/Mercury/Relay/PayPal balances in foreign currencies, foreign investment accounts, real property outside Brazil, and loans to non-residents.

The US LLC itself counts. The ownership interest, valued at fair market value (typically the LLC's net asset value), goes toward the threshold. Combined with US bank balances, a founder with even a modest US business can reach the $100,000 quarterly threshold faster than expected.

BACEN can impose fines up to R$250,000 for failure to file or for materially incorrect information, under Resolution BCB 131/2021.

Carnê-Leão: Monthly Tax Payment

Foreign-source income received by Brazilian residents is subject to Carne-Leao, a mandatory monthly income tax payment. Not annual. Monthly.

1. You receive income from the US LLC (distributions, salary, or service payments)
2. Convert to BRL at the BACEN PTAX exchange rate on the date received
3. Calculate monthly tax using the progressive IRPF rates above
4. Pay by the last business day of the following month

Missing monthly payments triggers interest at the Selic rate plus a fine of 0.33% per day of delay, up to 20%. Receita Federal provides the Carne-Leao Web application for calculating and generating the DARF payment slip.

Form 5472: US IRS Filing

A US single-member LLC owned by a non-US person must file Form 5472 with a pro forma Form 1120 every year, even with zero revenue.

The form reports: LLC details and foreign owner identification, all monetary transactions between the LLC and the owner (capital contributions, distributions, service payments, loans), and non-monetary transactions or transfers below fair market value.

Penalty for not filing: $25,000 per form, per year. If the IRS issues a notice and the form is not filed within 90 days, an additional $25,000 per 30-day period applies. There is no statutory cap.

Due April 15 for calendar-year filers, with a 6-month extension via Form 7004.

Many Brazilian founders who form through self-service platforms never learn about this requirement. By the time a CPA or contador identifies the gap, accumulated penalty exposure can exceed $50,000. More on Form 5472 penalties.

The "Cayman Sandwich"

For VC-backed Brazilian startups, a common multi-entity structure has emerged: a Cayman Islands holding company above a Delaware LLC or C-Corp, with a Brazilian operating company below.

Why it exists is simple. US investors want Delaware law for their term sheets, SAFEs, and investor rights documents. Brazilian founders need a local entity (LTDA or S.A.) for domestic operations and employees. The Cayman layer sits between them as a neutral holding jurisdiction with no corporate income tax, familiar to international investors.

Cayman Holdings (Exempted Company)
    └── Delaware LLC or C-Corp (US operations, IP holder)
    └── Brazilian LTDA or S.A. (local operations, employees)

Solo founders should not bother with this. Legal setup runs $15,000-$50,000. Annual maintenance across all three entities costs $10,000-$25,000/year. Multi-jurisdiction tax and legal counsel on top. It only makes sense when raising significant outside capital, typically Series A or later.

If you are raising: São Paulo firms like Pinheiro Neto, Mattos Filho, and TozziniFreire specialize in assembling these structures. Y Combinator's Latin American cohorts and Endeavor-backed startups commonly use this pattern.

Brazilian LTDA vs US LLC: Structural Comparison

Not every Brazilian founder needs a US LLC. The choice depends on where your customers are, where payments are processed, and what the operational footprint looks like.

MEI (Microempreendedor Individual) is the simplest Brazilian business structure: up to R$81,000/year, R$75.90/month tax covering INSS, ISS, and ICMS. Lowest friction for modest domestic revenue. No US banking or Stripe US access.

LTDA (Sociedade Limitada) is the Brazilian equivalent of an LLC. Limited liability, flexible management, no minimum capital. For a founder serving only Brazilian customers in BRL, a LTDA is simpler and avoids cross-border compliance entirely.

The US LLC makes sense when revenue is primarily in USD, customers are outside Brazil, and US banking or payment processing is operationally necessary. It is not inherently better than a Brazilian entity. It serves a different purpose.

The Full Compliance Map

Six filing obligations across two countries. That is the structural cost of operating a US LLC from Brazil without a tax treaty to simplify things.

FAQ

Can I form a US LLC without visiting the United States?

Yes. State filing, EIN by fax or phone, and bank account opening with Mercury, Wise, or Relay can all be done remotely from Brazil. No US visa or visit required. Banking is the step most likely to require extra documentation, but Brazilian nationals are not subject to enhanced country-level restrictions.

Is US LLC income taxable in Brazil even if I pay no US tax?

Yes. Receita Federal taxes worldwide income of Brazilian tax residents regardless of whether that income is also taxed elsewhere. A US single-member LLC with no US-source income typically owes no US income tax, but the same income is fully taxable in Brazil at rates up to 27.5%. Brazil allows a unilateral foreign tax credit for US taxes actually paid. If no US tax is paid, there is no credit to claim.

What is the difference between the CPF and the CNPJ?

CPF (Cadastro de Pessoa Fisica) is your individual taxpayer ID, equivalent to the US SSN for tax purposes. Every Brazilian citizen has one. CNPJ (Cadastro Nacional da Pessoa Juridica) is the business entity registration, equivalent to the US EIN. A US LLC does not have a CNPJ; it has a US EIN. Your CPF is what links US LLC income to your Brazilian personal tax filings (IRPF, Carne-Leao).

Do I need both a US LLC and a Brazilian entity?

Depends on where revenue comes from. Earning exclusively in USD from non-Brazilian customers? A US LLC alone works (while reporting income in Brazil via IRPF). Serving both markets? Many founders maintain both: a US LLC for international operations and a Brazilian MEI or LTDA for domestic BRL revenue. Running both adds compliance overhead but avoids the headache of processing BRL through a US entity or USD through a Brazilian one.

What happens to my US LLC if I leave Brazil and become a non-resident?

Brazilian tax residency ends when you deliver the Comunicacao de Saida Definitiva (Definitive Departure Declaration) to Receita Federal and file the final IRPF return. After that, Receita Federal no longer taxes worldwide income, only Brazilian-source income. BACEN CBE reporting and Carne-Leao obligations both cease. The US LLC continues operating normally, and US-side obligations (Form 5472, state annual report) remain unchanged. Your new country of residence then determines how LLC income is treated.

Key Takeaways

• Formation is mechanically identical to any other non-resident. The compliance afterward is not.
• Brazil has no income tax treaty with the US. One of the largest economies without one.
• Receita Federal taxes worldwide income at up to 27.5%. US LLC income is reportable as personal foreign-source income.
• Carne-Leao is a monthly obligation, not just annual. Miss it and penalties accrue daily.
• BACEN requires CBE reporting for foreign assets above $100,000 (quarterly) or $1,000,000 (annual)
• Form 5472 is required annually, even with zero revenue. $25,000 penalty per missed filing.
• The "Cayman Sandwich" is a VC-backed structure. Solo founders should skip it.
• Wise has strong Brazilian operations and BRL local accounts, which simplifies cross-border cash flow
• The US LLC is not inherently better than a Brazilian LTDA. The right structure depends on where customers are and what currency revenue arrives in.
