Carnê-leão and offshore reporting

Two compliance tools every cross-border investor meets: the carnê-leão and the duty to report foreign holdings. Both are about declaring and paying on time, separate from how much tax is ultimately due. Details below are as of the time of writing — verify.

The carnê-leão

The carnê-leão is the mandatory monthly self-assessment for certain income received from individuals or from abroad that had no Brazilian withholding — classically foreign rent, and income from work abroad. When it applies:

• You compute the tax monthly, applying the progressive table, and pay by DARF by the last business day of the following month.
• It is filled in the Receita's Carnê-Leão program, which then exports into your annual declaration.

Note: under the modernised regime, foreign financial investment income is reported annually, not via carnê-leão — but other foreign income (like rent) still uses the carnê-leão. Confirm which of your income types falls where.

Reporting foreign holdings

Declaring is separate from taxing. Two duties to know:

• IRPF (Bens e Direitos) — you must list all your foreign assets (brokerage balances, shares, property, crypto on foreign exchanges) on the annual declaration, regardless of whether they generated taxable gain.
• Declaração de Capitais Brasileiros no Exterior (CBE) to the Banco Central — a separate filing required when your total assets abroad exceed a threshold (commonly US$1,000,000, with a more frequent filing at a higher threshold — verify current values). This is not a tax; it is a central-bank census, but failing to file carries its own fines.

The takeaway

Even when no tax is due, the reporting obligations stand on their own. Missing the CBE or omitting a foreign account from Bens e Direitos creates penalties independent of any tax. Track your thresholds and let your accountant handle the filings. Educational only — verify all thresholds and deadlines.
