Should you form a US LLC if you live in Brazil?

Changed in 2026 — usually no. Solução de Consulta COSIT nº 56/2026, issued by Brazil's Receita Federal in early 2026, reclassified US LLCs held by Brazilian-resident partners as falling under the Privileged Tax Regime (RFP — regime fiscal privilegiado). The practical consequence: 15% IRPF on the LLC's profits is owed annually by the Brazilian resident regardless of whether profits were distributed. The historic timing advantage — Brazilian residents holding US LLCs without CFC attribution because they were treated as non-resident partners in a transparent US entity — is closed. For most Brazilian residents earning from a US-facing business, the cleaner path is now a Brazilian LTDA or, for early-stage operators, sole proprietorship through MEI or Simples Nacional. The conditional cases where the LLC still makes sense are narrow.

What this verdict applies to: Brazilian tax residents who would own a US single-member LLC or be a partner in a multi-member LLC. Does not apply to former Brazilian residents who have formally exited Brazilian tax residency (saída fiscal definitiva).

Why

For roughly fifteen years, Brazilian residents could hold US LLCs with relative tax efficiency. The IRS treated single-member and partnership LLCs as transparent. Brazil's CFC regime — focused historically on opaque foreign corporations with Brazilian-resident controllers — did not attribute LLC income annually because the LLC wasn't viewed as a CFC for Brazilian purposes. The result: profits accumulated inside the LLC weren't taxed in Brazil until distributed (or until the resident's Brazilian tax position changed).

COSIT 56/2026 closed that route. The ruling treats a US LLC with Brazilian-resident partners as triggering the RFP framework set out in Receita Federal Instrução Normativa 1.037/2010. The RFP designation applies when a foreign entity:

• Operates in a jurisdiction that taxes income at less than 20% (the US treatment of a transparent LLC effectively meets this test from Brazil's view, because the US does not tax the LLC itself).
• Permits structures that produce low or zero effective taxation in the foreign jurisdiction for the foreign owner.

Once the RFP classification attaches, the Brazilian resident owes 15% IRPF (Imposto de Renda da Pessoa Física) on the LLC's accrued profits annually — calculated on the resident's share of net profits, regardless of distribution. The ruling published prospectively from its 2026 issuance date.

This eliminates the structural reason most Brazilian residents formed US LLCs. The remaining motivations — Stripe access, USD revenue capture, US-customer credibility — survive, but they don't require a US LLC; they can be served by a Brazilian operating structure that invoices US clients and uses a multi-currency provider like Wise.

A second wrinkle: the ruling has practical implications for Brazilian residents who formed US LLCs pre-2026. Existing structures are not grandfathered. Profits accruing from 2026 forward attract IRPF. Brazilian advisers (Globalfy, Tellico, Bernhoeft, MRS Advogados, Migalhas commentators) are working through transition guidance, but the conservative read is that pre-existing LLC holders need to recompute their 2026 IRPF position and report accordingly.

When the verdict flips

Four real cases where forming a US LLC can still make sense for a Brazilian resident.

1. You're imminently exiting Brazilian tax residency. If you're executing a saída fiscal definitiva (formal exit from Brazilian tax residency) within 12 months and relocating to a jurisdiction where the LLC works cleanly, the LLC becomes a pre-positioned operating entity for your post-exit life. The pre-exit period requires careful timing.

2. The LLC has genuine US substance. US employees on payroll, US office space, US-based decision-making, US commercial nexus. Real operational substance can support arguments against full RFP attribution in fact-specific cases. Requires specialist analysis and typically only economical at meaningful annual revenue.

3. The LLC is held within a wrapping structure. Some Brazilian cross-border advisers structure the LLC inside a US C-Corp or another vehicle to manage the RFP classification. These are bespoke, expensive, and only worth doing at scale.

4. You're using the LLC strictly for non-business holdings. A specific case: holding a single US rental property or US securities portfolio inside the LLC. The income type matters; income from genuinely-passive US assets may attract a different analysis than active business income. Specialist review required.

Outside these cases, the verdict is don't form one.

What to do instead

For most Brazilian residents earning from a US-facing business, the cleaner path is one of the following.

Sociedade Limitada (LTDA) for the business operation. The standard Brazilian limited-liability vehicle. Tax treatment depends on regime: Simples Nacional for smaller revenue (up to roughly R$4.8M annually), Lucro Presumido or Lucro Real for larger operations. Cross-border revenue from US clients flows through the LTDA cleanly, with appropriate ISS / PIS / COFINS treatment for service exports and standard documentation for goods exports.

MEI (Microempreendedor Individual) or sole proprietorship for early-stage. If your annual revenue is under R$81K (the 2026 MEI cap, subject to change), MEI offers a simplified flat-rate path with monthly contributions and minimal compliance. Above that, sole proprietorship through a CNPJ-MEI graduation or direct LTDA formation is the standard route.

Specialist Brazilian cross-border tax adviser before any structural decision. Globalfy, Tellico, Bernhoeft, MRS Advogados, and Pontal Brazil are the firms documented in the OpenVentro research base as specialists in this niche. A consultation will produce a defensible structure for your specific facts and will account for the COSIT 56/2026 implications for any pre-existing LLC holdings.

Frequently asked

I formed my LLC in 2023. Am I grandfathered? No. COSIT 56/2026 applies prospectively from its 2026 issuance, but existing LLC holdings are not exempted from prospective IRPF on 2026-forward accruals. Recompute your 2026 position with a specialist.

Should I form a US C-Corp instead? Different vehicle, different rules. A C-Corp is opaque on both sides and engages a separate CFC analysis under Brazilian law. For active business income with US substance, it can work; for purely Brazilian-operated income, you're often back at a similar outcome through a different route. Not a guaranteed fix.

Does Form 5472 still apply for a Brazilian-owned US LLC? Yes. Form 5472 is a US-side IRS filing requirement for foreign-owned single-member LLCs. It's separate from the Brazilian IRPF analysis and continues to apply regardless of the COSIT 56/2026 reclassification on the Brazilian side.

Does it matter where I hold the US bank account — Mercury, Wise, US bank? No. The classification is at the entity level, not the bank-account level. The Brazilian Receita's analysis depends on entity classification under IN 1.037/2010, not on banking arrangements.

I'm a digital nomad outside Brazil for most of the year. Same rules? Only if you remain a Brazilian tax resident. Brazilian residency is determined by physical presence, residence intent, and formal status — not citizenship. If you've not executed a saída fiscal definitiva, you're still inside the rules. Confirm your residency status with a specialist before assuming otherwise.
