Unlock Your 2026 Tax Returns: Crucial Updates for US Investors Declaring Foreign Income & Capital Gains

The 2026 tax season brings significant changes for Brazilian residents investing abroad, fundamentally altering how foreign income and capital gains are reported and taxed. These updates, driven by Law No. 14.754/2023, aim to simplify the process while establishing a new, unified tax framework for international assets.

For individuals residing in Brazil with investments outside the country, understanding these new rules is paramount to ensure compliance and optimize tax liabilities. Key among the changes is the introduction of a flat 15% tax rate on all foreign earnings, replacing the previous complex system of monthly declarations and varying rates.

This shift eliminates the monthly ‘carnê-leão’ and GCAP declarations, consolidating the tax assessment into a single annual calculation. Furthermore, the exemption for monthly sales of assets up to R$ 35,000 has been abolished, meaning all profits are now subject to the new tax regime. As reported by Avenue, these adjustments are designed to align with the growing trend of Brazilians diversifying their portfolios internationally.

Understanding the New Tax Framework for Foreign Investments in 2026

The year 2026 marks a pivotal moment for Brazilian residents with international investments, as the directives established by Law No. 14.754/2023 are now fully integrated into the annual tax declaration process. This legislation has reshaped the landscape of reporting and taxing income and capital gains derived from assets held outside of Brazil, creating a more streamlined yet distinct approach for taxpayers.

Loss Compensation: A Strategic Advantage for Investors

One of the significant provisions benefiting investors under the new tax regime is the enhanced ability to offset losses. Under the 2026 tax declaration, individuals who incurred losses on their foreign investments during the 2025 tax year (ano-base 2025) can now officially report these deficits. This reporting allows for the compensation of these losses against future capital gains, potentially reducing or even eliminating the tax burden in subsequent years, such as the 2027 tax declaration.

This mechanism extends to losses previously declared in earlier tax filings. For instance, any documented losses from the 2025 tax year (ano-base 2024) can be used to offset gains realized in the 2025 tax year (ano-base 2025), provided these losses are of the same nature and were duly reported to the tax authorities. This provision is crucial for managing investment portfolios and mitigating the impact of market volatility on tax liabilities.

Unified 15% Tax Rate on Foreign Earnings

The core of the tax reform for foreign investments in 2026 is the implementation of a flat 15% tax rate applied uniformly across all types of foreign earnings. This consolidated rate simplifies the calculation and payment of taxes, eliminating the complexities previously associated with different income streams.

Previously, income such as dividends and rental income from foreign properties were subject to monthly declarations via the ‘carnê-leão’ system. Similarly, capital gains from financial instruments and other assets were taxed through the GCAP program. The new law consolidates these, meaning that all earnings from foreign investments – whether they are dividends, interest, rental income, or capital gains – will be subject to a single, annual 15% tax rate.

The tax calculation and payment process are now integrated into the official tax declaration software provided by the Receita Federal (Brazilian Federal Revenue). The ‘Programa Gerador de Declaração do IRPF 2026’ (PGDIRPF) will automatically generate a report titled ‘Demonstrativo de Apuração – Lei nº 14.754/2023’. This consolidated statement will detail the total tax due on foreign earnings, with a single payment guide issued for the annual tax liability. This shift signifies a major simplification, moving away from the monthly reporting burdens.

Rodrigo Poveron, founder of myProfit, a platform specializing in tax solutions for investors, notes the significance of these changes. He stated, “The recent changes made by the Federal Revenue regarding the taxation of foreign investments reinforce the natural path investors are taking by allocating their capital into foreign currency for greater diversification.” This perspective highlights how regulatory adjustments are often in sync with evolving investment strategies.

End of the R$ 35,000 Monthly Exemption for Asset Sales

A significant departure from previous regulations is the elimination of the monthly exemption for sales, liquidations, and redemptions of foreign assets valued below R$ 35,000. Under the previous rules, investors could realize profits up to this threshold monthly without incurring immediate tax liability. However, for the 2026 tax year, this exemption is no longer in effect.

Every dividend and profit generated from the sale or liquidation of foreign assets, regardless of the amount, will now be subject to the standard 15% tax rate. It is important to note that during the sale of an asset, there is no withholding tax at the source. The full transaction value is transferred to the investor, and the tax obligation arises only in the following year’s income tax declaration, based on the realized gains.

Abating US Taxes: Avoiding Double Taxation

For Brazilians investing in U.S. stock markets, a common concern is the potential for double taxation. The U.S. imposes taxes on dividend payments, which can be as high as 30% and are typically withheld at the source. However, a reciprocal tax agreement between Brazil and the United States prevents this double taxation.

This agreement allows for the abatement or credit of taxes paid to the Internal Revenue Service (IRS) against the tax liability owed to the Brazilian Receita Federal. When filling out the 2026 IRPF declaration (PGDIRPF), specific fields are available for ‘Imposto Devido’ (Tax Due), ‘Imposto Pago no Brasil / Exterior’ (Tax Paid in Brazil / Abroad), and ‘Saldo’ (Balance).

The system automatically calculates the balance due by comparing the tax paid in the U.S. with the 15% rate mandated by Brazilian law. If the U.S. tax rate paid on dividends is equal to or higher than the 15% Brazilian rate, no additional tax will be due in Brazil. If the U.S. tax paid is lower, the investor will be liable for the difference, effectively paying the higher of the two rates.

Accessing Organized Income Reports

To facilitate compliance with these new regulations, financial institutions like Avenue are providing clients with organized income reports in Portuguese. These reports are updated to reflect the current tax directives and are accessible through the client’s online account or application.

These reports consolidate all necessary information required by the Receita Federal for the 2026 tax declaration, simplifying the process of inputting data into the PGDIRPF software. Additionally, tutorials and guides are often available from financial service providers to assist investors in correctly filling out their tax forms, ensuring accuracy and adherence to the latest tax laws.
