Brazil’s Landmark Dual-VAT Reform Begins to Reshape Business Environment

Brazil is beginning the long, phased implementation of a Dual-Value Added Tax (VAT) system, the most significant change to the country’s tax code in decades, in an effort to simplify a tax regime that has long been a major obstacle to business. The landmark reform, established by Constitutional Amendment (EC) 132/2023, is designed to replace five existing federal, state, and municipal consumption taxes with a single, unified VAT structure.

The central goal of the new system is to slash the immense compliance burden on companies and eliminate the inefficient "tax-on-tax" effect, known as cumulatividade. Before the reform, companies in Brazil spent an estimated 1,958 hours a year to pay taxes, compared to a global average of just 206 hours. The new structure seeks to shift taxation to the destination—the location of the consumer—and standardise a system currently fractured by hundreds of different state and municipal rules.

The Dual-VAT Mechanism

The new structure creates two main taxes: the Contribuição sobre Bens e Serviços (CBS), which will be a federal tax, and the Imposto sobre Bens e Serviços (IBS), which will be administered jointly by states and municipalities. These two will gradually replace the five existing levies: the federal PIS, Cofins, and IPI, and the state and municipal ICMS and ISS.

Both the CBS and IBS are designed to be non-cumulative, a key feature of modern VAT systems worldwide. This means businesses will receive full credit for the tax paid on all their inputs—rent, software, equipment, and services—which was restricted and complicated under the old system. While the final combined rate is not yet fixed by law, government estimates for the standard rate circulated in 2026 reached as high as 27.9%, with some projections slightly lower. The high rate, however, is offset by the promise of full credit recovery, which should lower the effective tax burden for businesses that invest heavily.

A Seven-Year Transition

The transition period is designed to be long and gradual, running for seven years to give tax authorities and companies time to adapt their complex electronic invoicing systems. The phased rollout began in 2026 with a "test year," where a token combined rate (0.9% for CBS and 0.1% for IBS) was calculated alongside the existing taxes.

The new federal CBS is scheduled to be fully implemented in 2027, replacing PIS and Cofins. The state and municipal IBS will begin its gradual phase-in from 2029, progressively reducing the old ICMS and ISS taxes until the full dual-VAT system is operational in 2033. This multi-year transition creates immediate, practical compliance challenges for businesses, as they must manage two parallel tax systems—old and new—simultaneously for years.

The reform is viewed by the administration of President Luiz Inácio Lula da Silva and its supporters in Congress as a necessary structural change to unleash Brazil's long-term economic potential by lowering the "cost of doing business." However, the success of the system now depends on the passage and implementation of a long series of complementary laws that will set the final rates, define exemptions, and establish the specific rules of the new tax system.
