With the deadline for filing the 2025 Income Tax return approaching, taxpayers with investments need to be aware of the rules. Whether it's fixed income, variable income, or crypto assets, some errors can lead to the taxpayer being flagged for review. Understanding what should be reported and how to correctly fill out each field is essential to maintaining tax compliance.
Fabiano Azevedo, an accounting entrepreneur and ambassador for Omie , a cloud-based management platform, explains that "the obligation is determined by the Federal Revenue Service for: those who had income exceeding the exemption threshold, possess investments and assets that, when added together, exceed R$ 800,000, and those who had tax-exempt and non-taxable income exceeding R$ 40,000." Below, the expert explains how to file the tax return.
1 – Keep an eye on the changes for 2025
It is crucial to pay attention to the changes to ensure the correct fulfillment of your tax obligations. Regarding investments, an annual declaration becomes mandatory for those who earned income abroad from financial investments, profits, and dividends.
"The taxpayer must have the documents from the financial institutions on hand and select the Assets and Rights section in the Annual Income Tax Return program, choosing the option from the Applications and Investments group," explains Azevedo.
2 – Check your investments and pay attention.
It is important to cross-reference all sources of income with the income statements provided by banks, companies, and financial institutions, and carefully check which amounts need to be reported and in which section of the tax return program.
3 – Don't forget about international investments.
Financial transactions in foreign currency must be converted to Brazilian reais using the official exchange rate of the Central Bank on the date of the transaction. "Taxpayers need to understand whether there was income in international currency or just capital gains in order to convert, but it's also possible to declare it directly in foreign currency or crypto," says Azevedo. In the "Assets and Rights" section, it's possible to report balances in foreign currency and declare income or capital gains (if any) in the corresponding section.
4 – And not even cryptocurrencies.
Finally, according to the accountant, the same process for international investments applies to cryptocurrencies, adding information about the type (Bitcoin, Ethereum, etc.) and the exchange used. Gains from the sale of cryptocurrencies must be calculated monthly and reported if the profit exceeds R$35,000 in the month. "The rules may vary depending on the type of asset, but the general principle is proper conversion and precise detailing to avoid inconsistencies," concludes Fabiano.
