What double taxation is
Double taxation is when the same income is taxed in two countries at once. For Brazilians who receive, invest or work with abroad, it is a real risk, and understanding it helps you avoid paying tax twice on the same amount.
Why it happens: residence vs source
- Residence taxation: Brazil taxes the worldwide income of its tax residents, no matter where the money was earned.
- Source taxation: the country where the income is generated or paid also wants to tax it, often via withholding.
Where it shows up for Brazilians
- Income from abroad: contractors and/or freelancers and businesses paid by foreign clients; there may be withholding there and taxation here.
- Imported services: software, ads and tools, with PIS/COFINS-Importação, ISS and sometimes IRRF.
- Foreign investments: income and capital gains that also enter the Brazilian return.
Double-taxation treaties
- Define which country may tax each type of income — salary, dividends, royalties, services.
- Reduce or zero withholding in some cases.
- Set the relief method: usually a credit for tax paid in the other country.
Brazil and the US: reciprocity, not a treaty
This is the most relevant case for those working with the US, with a catch: there is no broad treaty between Brazil and the United States. Instead, Receita Federal recognizes reciprocity of treatment: within legal limits, US federal income tax paid can be credited against Brazilian IRPF (US state tax generally does not count). In 2025, the government signaled interest in advancing a formal treaty.
How to reduce it in practice
- Credit the tax paid abroad: offset in Brazil what was already paid there (via carnê-leão or the return), within the limits.
- Use the treaty, where one exists, applying the agreement’s rates and rules.
- Classify income correctly: receiving as an individual or business, and service exports, change the math considerably.
Where Ruvo helps, and where it doesn’t
- What Ruvo reduces: IOF (0%) and FX — from 0.3% to convert dollars to reais and 0.5% to 1% to convert reais to dollars — the financial cost of receiving, holding and spending.
- What Ruvo does not do: reduce income tax, ISS or PIS/COFINS, or replace tax planning.
