Between December 2023 and January 2026, Brazil enacted the largest restructuring of its tax system in over thirty years. The reform began with constitutional amendment EC 132/2023, was operationalized through complementary legislation (LC 214/2025 and LC 227/2026), and was supplemented by significant changes to personal and corporate income tax through Lei 15.270/2025.
The reform changes how consumption is taxed (the new IBS and CBS regime), how dividends are treated (the new IRPFM and dividend withholding regime), and how succession and gifts are taxed (mandatory progressive ITCMD and updated valuation rules).
The IBS and CBS framework: Brazil's new dual VAT EC 132/2023 · LC 214/2025
Brazil's previous consumption tax framework — a complex layering of federal taxes (PIS, Cofins, IPI), state tax (ICMS), and municipal tax (ISS) — produced one of the highest tax compliance burdens among major economies. The reform replaces most of this with a dual value-added tax structure:
IBS (Imposto sobre Bens e Serviços) — a state-and-municipal-level VAT, replacing ICMS and ISS. CBS (Contribuição sobre Bens e Serviços) — a federal-level VAT, replacing PIS and Cofins. Both operate on similar principles: tax at destination, full credit for inputs, and elimination of the cumulative cascade that characterized the previous system.
Transition timeline: The transition runs from 2026 through 2033. In 2026, IBS and CBS operate at test rates (0.1% IBS, 0.9% CBS) to allow taxpayers and tax administration to calibrate systems. Through 2032, the new and old systems run in parallel with progressively shifting weights. By 2033, the old taxes are fully extinguished.
Implications for foreign investors: The cash flow profile of investments in many Brazilian sectors will change as the transition progresses. Capital-intensive activities and long supply chains that previously bore the cumulative cascade of the old system will see effective tax burdens shift. Investments in real estate and regulated services receive specific transitional treatment under LC 214/2025 that warrants careful analysis. Foreign capital routing structures established under the previous regime should be reviewed.
IRPFM and the new dividend regime Lei 15.270/2025
For three decades, Brazilian dividends paid by domestic companies to shareholders were exempt from withholding tax at the shareholder level. Lei 15.270/2025 changed this in two ways, effective January 1, 2026:
The IRPFM (IRPF Mínimo). Personal taxpayers with annual income above R$600,000 are subject to a minimum effective income tax rate of up to 10%. The base includes dividends previously exempt. The minimum rate operates as a top-up: if the taxpayer's effective rate from other sources is already at or above 10%, no additional tax is owed.
Dividend withholding for large monthly distributions. Distributions exceeding R$50,000 per month from a single company to a single individual recipient are now subject to 10% withholding at source. Mechanisms prevent double taxation when total tax burden across the entity and individual exceeds defined thresholds.
Implications for foreign investors: The change primarily affects Brazilian-resident shareholders. Foreign-resident shareholders of Brazilian companies remain subject to the previous treaty-based withholding regime. However, the change has indirect implications for mixed Brazilian-international family structures and operational structures that distributed substantially through dividends to Brazilian-resident managers or partners. The structural advantage of Brazilian holding companies has been recalibrated, not eliminated. The arithmetic now requires recalculation under the new framework.
ITCMD: mandatory progressivity and new valuation rules EC 132/2023 · LC 227/2026
EC 132/2023 mandated that all Brazilian states adopt progressive ITCMD (the state-level inheritance and gift tax). LC 227/2026 reinforced this with general federal norms. As of mid-2026, sixteen states have already implemented progressive ITCMD with rates typically ranging from 1% to 8%. Eleven states still operate under fixed-rate regimes while their legislatures process progressivity legislation. The transition is expected to be complete by 2027.
LC 227/2026 also clarified valuation rules: the base for ITCMD calculation must reflect the market value of transmitted assets at the time of the taxable event. For corporate participations in family holdings, valuation must reflect underlying assets at market value. This is a material change — the previous practice of holding Brazilian assets through structures with reduced ITCMD exposure via historical book values may produce different outcomes under the new rules.
What the reform does not change
Foreign capital registration. The Banco Central registration regime continues to apply. The documentary memory of foreign capital — properly registered at entry — remains the basis for clean repatriation, distribution, and exit.
Treaty network. Brazil's double taxation treaties continue to govern the cross-border treatment of dividends, interest, and royalties paid to foreign residents.
Holding company structures. Brazilian holding companies remain a viable instrument for many investment configurations. The arithmetic has changed; the instrument has not.
What this means for capital structure decisions in 2026–2027
The transition period creates a window in which specific planning choices interact in ways that did not exist under either the old or the new system alone.
For new investments, the reform makes structural decisions more consequential. The choice between holding through a Brazilian company versus direct investment, between distributing through dividends versus alternative mechanisms, between holding real assets in personal name versus a configured company — each now has different consequences than in 2025, and different consequences than it will have in 2033.
For existing investments, the reform creates a window for structural review. In most cases, this is a calibration exercise rather than a complete restructuring.
The framework principle from Brazil Market Entry applies here: structural decisions are part of the investment decision, not closing formalities. The cost of leaving structural decisions to default has not decreased with the reform. In several respects, it has increased.

Does the Brazil tax reform affect foreign investors directly?
Selectively. Foreign-resident investors remain subject to the previous treaty-based withholding regime for most cross-border income. They are affected indirectly through the changed economics of Brazilian holding structures, the new consumption tax framework's impact on operating businesses, and the ITCMD changes for any Brazilian-resident family members.
When does the Brazilian tax reform take full effect?
The transition runs from 2026 through 2033. IBS and CBS operate at test rates in 2026, with progressive scaling through 2032 and full implementation in 2033. The IRPFM and new ITCMD rules took full effect in 2026.
Should foreign investors restructure existing Brazilian investments because of the tax reform?
Existing structures should be reviewed against the new framework. In most cases, restructuring is not required, but calibration of distribution patterns, capital routing, and exit mechanisms may improve outcomes. The specific answer depends on the specific structure and investment.
Will Brazilian dividends remain attractive to foreign investors after the reform?
For foreign-resident investors, the dividend treatment under the reform is broadly comparable to the previous regime. The IRPFM affects Brazilian-resident shareholders directly. Brazil's dividend yield environment remains competitive against most major emerging markets, but the calculus is more nuanced than under the previous regime.
