Brazil Supreme Court Upholds Key ICMS Tax Credits for Fuel Distributors

The Brazil Supreme Court (STF) has definitively settled a major, multi-billion real tax dispute in favor of the country’s largest fuel distributors, ruling that they can maintain state Value-Added Tax (ICMS) credits generated from internal purchases of petroleum derivatives. The binding decision, concluded on September 8, 2026, provides significant fiscal certainty for the sector after years of legal wrangling with state governments.

The ruling, which resolves General Repercussion Theme 1.258, centered on a case led by Raízen Combustíveis S.A. against the State of Minas Gerais. The dispute was over the ability to claim the ICMS credit—a state-level VAT—paid when a distributor buys fuel within a state (the internal operation). State tax authorities argued that if the distributor later transfers the fuel to another state, the credit should be annulled because the subsequent interstate transfer is immune from ICMS taxation in the state of origin, with the tax instead being paid to the state of consumption.

The core of the matter was the constitutional principle of non-cumulativeness, which allows companies to offset the tax paid on their purchases against the tax collected on their sales, preventing a cascading tax effect. The Supreme Federal Court rejected the states' argument, concluding that the constitutional immunity on the interstate transfer does not retroactively cancel the tax credit legitimately generated during the initial internal purchase. Preserving the credit prevents the ICMS from being transformed into an unrecoverable business cost for the distributors.

The decision prevents the annulment of these accumulated tax credits nationwide and is a massive financial relief for the sector. While the exact total value is debated, a study presented during the case estimated that if the states’ position had prevailed, the additional cost to the fuel chain could have reached R$ 860 million in 2024 alone. The ruling removes a major source of financial uncertainty and reinforces the protection of the non-cumulativeness principle in Brazil’s complex tax code.

What it touches

The resolution of this ICMS dispute directly benefits major fuel distributors and logistics companies operating in Brazil, including publicly listed entities such as Raízen (RAIZ4 on B3) and Vibra Energia (VBBR3 on B3). By maintaining the tax credits, the companies avoid a significant increase in their operating costs, bolstering financial stability for a sector critical to Brazil's logistics and consumer prices.
