Tax Calendar · Offshore & Compliance

The invisible calendar of the international investor

Understand the tax and compliance routines that every offshore structure must meet throughout the year.

Investing abroad is no longer a topic reserved for large fortunes and has become part of the wealth planning of Brazilian families of many different profiles. Well structured, this diversification goes beyond preserving purchasing power: it also opens access to more mature markets, sustaining wealth protection and the transfer of a legacy across generations.

However, the step that follows the decision to invest is rarely considered in internationalization processes. Every international structure carries tax and compliance obligations spread throughout the year, under authorities as distinct as the Brazilian Federal Revenue Service, the Central Bank of Brazil, the U.S. tax authorities and the corporate registries of the countries where the structures are based (for example: BVI, Cayman, Bahamas, Panama and Uruguay, among others).

It is what we call the “invisible” calendar. Invisible because these dates come with no automatic reminders — it is up to investors to know them, or to have experienced professionals advising them on the subject.

In this article, we bring together the complete calendar that investors with capital abroad need to know, with the deadline for each obligation and a straightforward explanation of each one (we will publish dedicated articles on the specifics of each obligation throughout the year). Browse the timeline below by date and, right after it, see these obligations grouped by jurisdiction. The dates reflect the most common scenarios — calendar-year financial periods and the most widely used jurisdictions; specific deadlines may vary depending on the U.S. state of incorporation and on each structure’s financial year.

Brazil

Apr 5
DCBE (Declaration of Brazilian Capital Abroad)

Mandatory declaration for investors (individuals or legal entities) who are Brazilian tax residents and hold US$ 1 million or more in assets abroad on December 31 of each year. It is an independent filing, unrelated to the income tax return and with a different reporting format, which causes a great deal of confusion and filing errors.

Important: this declaration is required quarterly from those holding more than US$ 100 million outside Brazil.

May 31
DIRPF (Brazilian Individual Income Tax Return)

Annual return, filed by the last business day of May and required based on certain income and wealth thresholds. In practice, every investor with capital outside Brazil ends up meeting the filing criteria and must observe the tax requirements introduced by Law No. 14,754/2023, which demands an annual assessment of the results of investments and structures abroad.

United States

Mar 15
Tax Return (U.S. income tax filing)

Filing submitted by U.S. taxpayers to the country's federal tax authority (the Internal Revenue Service, IRS) and to state revenue agencies. The first due date is dedicated to companies taxed as Partnerships and S-Corporations.

Varies by state
Annual Report

Filing submitted to the state where the structure is registered, renewing the corporate registration and keeping the company in good standing with the local government. The deadline depends on the state of incorporation: in Florida, it is due by May 1 for LLCs and Corporations; in Delaware, Corporations file by March 1 and LLCs by June 1. Other states have their own rules and dates.

Apr 15
Tax Return: C-Corporations and U.S. tax residents

The specific deadline for companies taxed as C-Corporations and for individuals who are U.S. tax residents.

May 31
Registered agent annual fee

Due date of the registered agent fee — a mandatory, indispensable figure for maintaining companies in the U.S.

Jun 15
Tax Return: non-residents

Deadline for non-residents of the U.S. with U.S.-source income, who must file an income tax return reporting all local income.

Note: for all Tax Return deadlines, it is common to request a six-month filing extension with no late-filing penalty. Even with the extension, the tax itself remains due on the return's original due date.

BVI, Cayman and Bahamas

May 31
Government and registered agent annual fees

Although these countries do not tax the income generated by the companies based there, they require payment of an annual fee and the appointment of a registered agent (a mandatory local firm for maintaining the structures). The annual fee is split into two due dates, depending on when the offshore company was incorporated, with May dedicated to companies incorporated in the first half of the year.

Jun 30
Economic Substance

Annual demonstration that the structure actually operates as it was set up to operate, with possible additional reporting requirements depending on the specific operation of the international structure. The deadline follows each entity's financial period: June 30 applies to financial years ending December 31, which is the most common scenario. Companies that kept their own financial period — generally tied to the anniversary of incorporation — have specific deadlines, counted from the end of their financial year.

Sep 30
BVI Financial Annual Return

Annual financial report, disclosing information related to the structure's Financial Statements. The deadline is nine months after the end of the company's financial year — September 30 for financial years ending December 31.

Nov 30
Government and registered agent annual fees

Deadline for companies incorporated in the second half of the year.

A well-maintained structure runs in silence

The length of this list should not scare anyone away from international investing. It should simply make clear that an offshore structure requires ongoing professional care — not just attention at the moment of incorporation and when the investments are made.

When that care is in place, the result is discreet by nature. Deadlines are met before they become urgent, obligations are resolved without the family having to think about them, and the year goes by without fines, notices or surprises.

Regulatory complexity demands that Brazilian investors treat the maintenance of their international wealth not as an incidental cost, but as an essential part of their strategy for preserving a legacy across generations.
