Résidence fiscale en Brazil : le test des 183 jours
Seuil de 183 jours
Comment la règle des 183 jours fonctionne en Brazil
Brazil counts 183 days within any 12 month period. Becoming a resident triggers worldwide income taxation.
Fenêtre glissante de 12 mois. Cela signifie que le décompte regarde en arrière à partir de n'importe quelle date donnée, pas seulement la fin de l'année civile. Une fenêtre glissante est plus difficile à suivre manuellement car le chiffre change chaque jour.
Si vous dépassez 183 jours, Brazil peut imposer vos revenus mondiaux en tant que résident fiscal. Les conséquences exactes dépendent de votre situation personnelle, des conventions fiscales applicables et du type de revenus concerné.
Comment le décompte fonctionne
How residency starts in Brazil depends on your visa. A permanent visa or residency makes you a tax resident from the day you arrive. Anyone on a temporary visa has 183 days of presence within a rolling 12 month window before residency kicks in. Once you are in, you stay in until you formally file the departure paperwork: the Comunicação de Saída Definitiva, followed by the Declaração de Saída Definitiva. Skip those forms and Brazil keeps treating you as resident even after you have left the country for good.
Ce qui compte comme un jour
Both the day you arrive and the day you leave count. The window is rolling rather than tied to the calendar, so Brazil counts any combination of 183 days inside the prior twelve months.
Au-delà du simple décompte
For permanent visa holders the day count is beside the point: you are resident from day one. The thing that catches people leaving Brazil is the departure declaration. Without it, the Receita Federal keeps taxing your worldwide income for as long as the paperwork sits unfiled.
Régimes fiscaux spéciaux
Brazil has no special regime for incoming expats. Residents pay progressive income tax on their worldwide income, topping out at 27.5%, and can credit foreign tax paid under any applicable treaty.
Conventions fiscales
For a country its size, Brazil's treaty network is thin. The most obvious gap is the absence of any income tax treaty with the US. Where treaties do exist, they generally follow the OECD tiebreaker model with some local adjustments.
Questions fréquentes
When does Brazilian tax residency start?
It depends on your visa. A permanent visa makes you resident from your arrival date. With a temporary visa, residency kicks in once you have spent 183 days in Brazil within any 12 month period since you arrived.
What is the departure declaration?
Two forms, filed when you are leaving Brazil for good. The Comunicação de Saída Definitiva is due within 30 days of departure; the Declaração de Saída Definitiva follows in the next year's tax return season. Until both are filed, Brazil keeps treating you as a resident taxpayer.
Is there a tax treaty between Brazil and the US?
Not as of 2026. With no bilateral income tax treaty in place, each side runs its own foreign tax credit, and where the two credits do not line up you can end up paying tax twice on the same income.
