Why there is no comprehensive treaty
Brazil and the US have negotiated a bilateral tax treaty for decades but it has never been ratified. Some limited information exchange and FATCA-related arrangements exist, but they do not reduce US withholding rates or provide foreign tax credit mechanisms.
Practical consequence: US-source FDAP paid to your Wyoming LLC, when attributable to a Brazilian-resident owner, faces the default 30% US withholding. There is no treaty rate to claim.
What default 30% withholding applies to
| Income type | Default US rate | Brazil status |
|---|---|---|
| US-source dividends | 30% | No treaty relief |
| US-source portfolio interest | 30% | Most exempt under domestic US rules |
| US-source royalties | 30% | No treaty relief |
| Business profits without US PE | Generally not taxed | No US tax regardless of treaty |
| ECI from US trade or business | Graduated US rates | Same regardless of treaty |
Brazilian CFC rules (Lei 12.973/2014)
Brazil's CFC rules under Lei 12.973/2014 are aggressive. Brazilian-resident shareholders of foreign companies are required to report and tax certain foreign-company profits, with limited deferral. The rules can apply to a US Wyoming LLC depending on how Receita Federal classifies it.
Most Brazilian founders we serve work with a Brazilian CPA to structure the LLC so that operating-business income flows through cleanly and CFC adjustments are minimized. The key driver is documenting that the LLC's income is active operating profit, not passive holding income.
Workarounds for Brazilian founders
Operating business profits typically stay outside US tax under non-resident pass-through rules. Brazilian founders running SaaS, agency, services, or e-commerce through a Wyoming LLC face zero US federal tax on operating revenue, plus Brazilian tax on the pass-through income.
For US dividend investments, Brazilian residents typically use other structures (direct Brazilian brokerage holdings, certain holding companies) for better tax treatment. Avoid routing US dividend income through the LLC where possible to skip the 30% FDAP.
Common mistakes by Brazilian founders
- Routing US dividend investments through the LLC and paying 30% FDAP unnecessarily
- Not addressing Brazilian CFC rules with a CPA
- Missing DBE (Declaração de Bens no Exterior) for foreign assets above thresholds
- Not filing Form 5472 + 1120 ($25K penalty)
- Assuming a treaty will be ratified soon (no clear timeline)
