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

Brazil is Latin America's largest tech economy. Over 1,500 tech startups raised funding in 2024-2025. Firstbase operates a São Paulo office specifically to serve Brazilian founders forming US entities. But there is a structural gap that most formation guides gloss over: Brazil has no income tax treaty with the United States. Brazil is one of the largest economies in the world without one. Receita Federal (the Brazilian IRS) taxes worldwide income of Brazilian residents at progressive rates up to 27.5%. There is no treaty-based relief, no reduced withholding, and no tie-breaker rule for determining tax residency. Every dollar the US LLC earns is reportable — and potentially taxable — in Brazil, with limited mechanisms for avoiding double taxation.

I have operated US entities as a cross-border founder since 2007, and I have seen this exact structural gap catch founders who assumed the US LLC would be "tax-free" because it is a disregarded entity for US purposes. 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 accordingly.

This guide covers the full formation process and — critically — 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 ($100 formation + $60/year), no member disclosure, no state income tax, and minimal ongoing compliance.

Delaware is the right pick if raising venture capital from US investors. The Court of Chancery and its body of corporate case law are what US investors and their lawyers expect. For a solo founder running a SaaS product or freelance business, this infrastructure adds cost without benefit.

New Mexico is the cheapest option — $50 one-time, no annual reports, no recurring state fees. The trade-off is less established case law and fewer formation services with New Mexico-specific expertise.

No US state restricts LLC formation by nationality. All three accept Brazilian citizens and residents on the same terms as any other non-resident.

Step 2: Form the LLC

Formation requires three components:

1. Registered agent — A US-based person or company designated to receive legal documents on behalf of the LLC. Required by every state. Costs $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 structure, and profit distribution. Single-member LLCs benefit from having one — it establishes the separation between personal and business assets.

A note on the CPF (Cadastro de Pessoa Física): The CPF is Brazil's national taxpayer identification number, issued by Receita Federal. US LLC formation does not require a CPF — the IRS and state filing offices do not ask for it. But the CPF is central to Brazilian tax reporting. When reporting the US LLC's income on the Brazilian IRPF (annual income tax return), the CPF links the foreign entity's income to the Brazilian resident's tax file. Every Brazilian resident already has one.

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

Step 3: Get an EIN

An Employer Identification Number is the LLC's US tax ID. Required for banking, tax filing, and payment processor setup.

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

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 (BRT) is UTC-3. During US standard time (November-March), BRT is ET+2 — when it is 9:00 AM in São Paulo, it is 7:00 AM in Philadelphia. During US daylight saving time (March-November), BRT is ET+1. The IRS international phone line operates Monday-Friday, 6:00 AM to 11:00 PM Eastern at (267) 941-1099. Brazilian founders calling in the morning can reach the IRS during its earliest hours, when hold times tend to be shorter.

The online EIN application does not work without an SSN. Mail submission (IRS, Cincinnati, OH 45999) takes 4-6 weeks. The fax or phone method is significantly faster.

Step 4: Open a US Bank Account

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

Wise is particularly relevant for Brazilian founders. Wise operates extensively in Brazil, holds a license from Banco Central do Brasil, and offers BRL local accounts. A Brazilian founder with a Wise Business account can hold both USD (for the US LLC) and BRL (for Brazilian operations) in the same platform, with competitive conversion rates. This does not eliminate the need for a dedicated US business bank account (Mercury or Relay), but it streamlines cross-border transfers between Brazil and the US.

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 structural choice: A Brazilian founder selling primarily to US or global customers processes payments through Stripe US (via the LLC, with a US EIN and US bank account). A founder selling to Brazilian customers processes through Stripe Brazil, Pagar.me, or MercadoPago (via a Brazilian entity with a CNPJ). Many founders who serve both markets use both — a US LLC for international revenue and a Brazilian LTDA or MEI for domestic revenue.

The Compliance Layers

Everything above — state selection, formation, EIN, banking, payments — is mechanical. The formation services handle it. What follows is where the structural risk sits for Brazilian founders specifically.

Receita Federal: Worldwide Income Taxation

Brazil taxes worldwide income of its tax residents. This is the single most important structural fact for a Brazilian founder operating a US LLC.

How it works:

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. Brazil's 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 Física — individual income tax).

Progressive tax rates (2026 IRPF):

At current exchange rates (approximately R$5.0-5.5 per USD), a US LLC generating $2,000/month in profit exceeds the 27.5% bracket. The effective tax rate varies depending on deductions and the specific calculation method, but the marginal rate of 27.5% applies quickly 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. This is accurate for US federal income tax — if the LLC has no US-source income, there is typically no US income tax liability. But "no US tax" does not mean "no tax." Receita Federal treats the LLC's worldwide income as the founder's personal income and applies Brazilian rates accordingly.

No US-Brazil Tax Treaty

This is the structural gap that separates Brazil from most other major economies.

What having no treaty means in practice:

• No reduced withholding rates. If the US LLC receives income subject to US withholding (dividends from US investments, certain royalties), the default 30% US withholding rate applies. Countries with US tax treaties typically negotiate this down to 10-15%.

• No tie-breaker rules. Tax treaties include provisions for determining which country has primary taxing rights when an individual qualifies as a tax resident of both countries. Without a treaty, both countries can assert full taxing rights simultaneously.

• No mutual agreement procedure. Treaties provide a mechanism for the two countries' tax authorities to resolve disputes. Without one, each country's tax authority operates independently.

• Foreign tax credit is available unilaterally, but with limitations. Brazil allows a credit for taxes paid to foreign governments under the principle of reciprocity (Brazil's tax code, Article 26 of Law 9.249/1995). The credit is limited to the amount of Brazilian tax attributable to the foreign income — it cannot reduce Brazilian tax on Brazilian-source income. And it requires documentation that the foreign tax was actually paid.

For comparison: India, China, the UK, Germany, Canada, Australia, Japan, and South Korea all have income tax treaties with the United States. Brazil does not. This means 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)

The Banco Central do Brasil (BACEN) requires Brazilian residents to report foreign assets through the CBE (Declaração de Capitais Brasileiros no Exterior).

Reporting thresholds:

What counts as "foreign assets" for CBE purposes:

• US LLC ownership interest (at fair market value)
• US bank account balances
• Wise, Mercury, Relay, PayPal balances held in foreign currencies
• Foreign investment accounts
• Real property outside Brazil
• Loans to non-residents

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

Penalties for non-filing: BACEN can impose fines of up to R$250,000 for failure to file the CBE or for filing with materially incorrect information, under Resolution BCB 131/2021. The fine amount depends on the severity and duration of the violation.

Carnê-Leão: Monthly Tax Payment

Foreign-source income received by Brazilian residents is subject to Carnê-Leão — a mandatory monthly income tax payment.

How it works:

1. The Brazilian resident receives income from the US LLC (distributions, salary, or service payments)
2. The income is converted to BRL at the exchange rate on the date received (BACEN PTAX rate)
3. The monthly tax is calculated using the progressive IRPF rates above
4. Payment is due by the last business day of the month following receipt

The monthly calculation requirement is not optional. Unlike the annual IRPF return (which reconciles everything), Carnê-Leão is a monthly obligation. Missing monthly payments triggers interest (Selic rate) and a fine of 0.33% per day of delay, up to 20%.

Receita Federal provides the Carnê-Leão Web application for calculating and generating the DARF (Documento de Arrecadação de Receitas Federais) payment slip.

Form 5472: US IRS Filing

A US single-member LLC owned by a non-US person is classified as a "foreign-owned US disregarded entity" by the IRS. This entity is required to file Form 5472 with a pro forma Form 1120 every year — even with zero revenue.

What is reported:

• LLC details and foreign owner identification
• All monetary transactions between the LLC and the foreign owner — capital contributions, distributions, payments for services, loans
• Non-monetary transactions and 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 continuation penalty of $25,000 per 30-day period applies. There is no statutory cap.

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

Many Brazilian founders who form US LLCs through self-service platforms are not informed about this requirement. By the time a CPA or contador identifies the gap, the 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 sitting above a Delaware LLC or C-Corp, with a Brazilian operating company (LTDA or S.A.) below.

Why it exists:

• US investors prefer Delaware entities. Their standard term sheets, SAFE agreements, and investor rights documents are drafted for Delaware law.
• Brazilian founders need a Brazilian entity (LTDA or S.A.) for domestic operations, employment, and BRL revenue.
• The Cayman layer provides a neutral holding jurisdiction that is familiar to international investors, has no corporate income tax, and sits outside both US and Brazilian direct tax reach.

The structure looks like this:

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

This is not a solo founder structure. The compliance cost of a Cayman-Delaware-Brazil arrangement — legal setup ($15,000-$50,000), annual maintenance ($10,000-$25,000/year across all three entities), and multi-jurisdiction tax and legal counsel — is justified only when raising significant outside capital (typically Series A or later). For a solo founder or early-stage bootstrapper, the overhead exceeds the benefit.

The structure is well-documented in Brazilian startup ecosystems. Law firms in São Paulo (e.g., Pinheiro Neto, Mattos Filho, TozziniFreire) specialize in assembling these arrangements. Accelerators like Endeavor and Y Combinator's Latin American cohorts commonly use this pattern.

Brazilian LTDA vs US LLC: Structural Comparison

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

MEI (Microempreendedor Individual) is a simplified Brazilian business structure for individuals earning up to R$81,000/year. The monthly tax (DAS-MEI) is approximately R$75.90/month, covering INSS, ISS, and ICMS. It is the lowest-friction option for Brazilian founders with modest domestic revenue. It does not provide US banking or Stripe US access.

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

The US LLC is the right structure when the founder's revenue is primarily in USD, customers are outside Brazil, and US banking or US payment processing is operationally necessary. It is not inherently "better" than a Brazilian entity — it serves a different operational purpose.

The Full Compliance Map

Six separate filing obligations across two countries. This is the structural cost of operating a US LLC from Brazil without a tax treaty to simplify the interaction between the two tax systems.

FAQ

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

Yes. The entire process — state filing, EIN by fax or phone, and bank account opening with Mercury, Wise, or Relay — can be completed remotely from Brazil. No US visa or visit is required for LLC formation. Banking is the step most likely to require additional 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 in another country. A US single-member LLC with no US-source income typically has no US income tax liability — but the same income is fully taxable in Brazil at rates up to 27.5%. The absence of a US-Brazil tax treaty means there is no treaty-based mechanism to coordinate the tax treatment. Brazil allows a unilateral foreign tax credit for US taxes actually paid, but if no US tax is paid, there is no credit to claim.

What is the difference between the CPF and the CNPJ?

The CPF (Cadastro de Pessoa Física) is the individual taxpayer identification number for Brazilian residents — equivalent to the US SSN for tax purposes. Every Brazilian citizen has one. The CNPJ (Cadastro Nacional da Pessoa Jurídica) is the business entity registration number — equivalent to the US EIN. A US LLC does not have a CNPJ; it has a US EIN. The founder's CPF is used for Brazilian personal tax filings (IRPF, Carnê-Leão) that include the US LLC's income.

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

It depends on where revenue comes from. A founder earning exclusively in USD from non-Brazilian customers can operate through a US LLC alone (while reporting the income in Brazil via IRPF). A founder with both US/global and Brazilian domestic customers often maintains both — a US LLC for international operations and a Brazilian MEI or LTDA for domestic BRL revenue. Running both adds compliance overhead but avoids trying to process BRL transactions through a US entity or USD transactions through a Brazilian one.

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

Brazilian tax residency ends when the individual delivers the Comunicação de Saída Definitiva (Definitive Departure Declaration) to Receita Federal and files the final IRPF return (Declaração de Saída Definitiva). After that, Receita Federal no longer taxes worldwide income — only Brazilian-source income. The US LLC continues to operate normally. BACEN CBE reporting obligations cease for non-residents. Carnê-Leão obligations cease. The US-side obligations (Form 5472, state annual report) remain unchanged. The tax residency of the new country of residence then determines how the LLC income is treated.

Key Takeaways

• US LLC formation for Brazilian residents is mechanically straightforward — the formation process is identical to any other non-resident
• Brazil has no income tax treaty with the United States — one of the largest economies without one
• Receita Federal taxes worldwide income at up to 27.5%, and US LLC income is reportable as the founder's personal foreign-source income
• Carnê-Leão (monthly tax payment) applies to foreign-source income — this is a monthly obligation, not just annual
• BACEN requires CBE reporting for Brazilian residents with foreign assets above $100,000 (quarterly) or $1,000,000 (annual)
• Form 5472 is required by the IRS annually, even with zero revenue — $25,000 penalty per missed filing
• The "Cayman Sandwich" (Cayman + Delaware + Brazilian entity) is a VC-backed structure, not a solo founder structure
• Wise has strong Brazilian operations and BRL local accounts, making it particularly useful for Brazilian founders managing cross-border cash flow
• The US LLC is not inherently superior to a Brazilian LTDA — the right structure depends on where customers are and what currency revenue arrives in
