Background
Brazilian federal law imposes PIS (Social Integration Program) and Cofins (Social Security Financing) contributions on the retail sale of cigarettes and small cigars through a forward tax-substitution regime: manufacturers, importers, and wholesalers pay these contributions in advance on behalf of downstream retailers. To achieve heightened taxation of tobacco products for public-health and selective-tax reasons, Congress chose not to raise the contribution rates but instead to inflate the tax base artificially. The base is calculated by multiplying the government-mandated retail list price by a statutory multiplier — 291.69% for PIS and a coefficient of 3.42 for Cofins — so the taxable base is roughly three times the actual shelf price. Retailers are legally required to sell at the listed price and may not deviate from it.
Retail food merchant Loli Comércio de Alimentos Ltda., a cigarette and cigarillo retailer, sought a refund of what it characterized as excess contributions. It argued that the Supreme Court’s binding precedent in Theme 228 of general repercussion (RE 596,832, decided June 29, 2020) — which holds that “the refund is due for PIS and Cofins collected in excess under the tax-substitution regime when the actual taxable base of the transactions is lower than the presumed base” — entitles retailers to recover the gap between the inflated statutory base and either (a) the actual list price itself (eliminating the multiplier/coefficient entirely) or (b) any actual sale price below the list price. The Federal Union opposed, contending the inflated base is a fixed legislative value, not a mere presumption, so Theme 228 does not apply, and that permitting a refund would gut the extrafiscal anti-tobacco policy. The Fourth Regional Federal Court (TRF-4) sided with the Union, and Loli appealed to the STJ.
The STJ’s Second Panel had already ruled against retailers on the identical question in REsp 2,135,871 and REsp 2,199,044 (both decided October 16, 2025, Rapporteur Min. Afrânio Vilela), holding that the tobacco-sector tax base is a “legally fixed value,” not a presumed one, and that applying Theme 228 would undermine the regime’s extrafiscal public-health purpose. Given the breadth of the issue — affecting all cigarette retailers nationwide — Rapporteur Minister Maria Thereza de Assis Moura proposed designating it as a binding repetitive controversy to be resolved by the full First Section.
The Court’s Holding
The First Section, unanimously, designated REsp 2,177,940 and REsp 2,215,075 as representative resources under the repetitive-appeals procedure set out in Articles 1,036–1,037 of the Code of Civil Procedure and Articles 256–256-X of the STJ’s Internal Rules (RISTJ). The court has not yet resolved the underlying merits; this decision is a procedural ruling that formally certifies the question as a binding repetitive issue and assigns it for definitive resolution by the full First Section.
The legal question certified for resolution is: “Whether the difference between the amount prepaid based on the multiplication of the list price by a multiplier or coefficient and the amount calculated based on the actual sale price effectively practiced must be refunded to retail sellers of cigarettes and cigarillos in respect of contributions to the Social Integration Program (PIS) and to the Social Security Financing Fund (Cofins).” This formulation captures both sub-controversies identified by the rapporteur: whether the multiplier/coefficient may be set aside entirely (replacing the inflated base with the retail price), and whether below-list sales trigger a partial refund even though such sales would constitute a legal violation of the price-control rules.
Pending the merits decision, the First Section simultaneously ordered the nationwide stay of all pending individual and collective proceedings addressing this question, whether in lower federal courts or in any court across Brazil, pursuant to Article 1,037(II) of the CPC. The STJ indicated that a broad stay — rather than a stay limited to cases already before the STJ — was warranted given the large number of affected taxpayers, the absence of risk of prejudice to ancillary matters, and the need to prevent unequal treatment among retailers while the binding answer is pending. The Federal Prosecution Service (MPF) was given 15 days to submit a fresh opinion.
Key Takeaways
- This decision does not resolve whether cigarette retailers are entitled to refunds; it certifies the question for a binding ruling by the STJ’s full First Section that will bind courts throughout Brazil.
- All pending lawsuits — individual or class — in which retailers seek PIS/Cofins refunds based on the gap between the inflated statutory base and actual cigarette sale prices are immediately stayed nationwide until the First Section issues its merits decision.
- The STJ’s Second Panel had previously ruled against retailers (REsp 2,135,871 and REsp 2,199,044, Oct. 2025), but that precedent does not bind the First Section, whose forthcoming ruling will supersede it.
- PIS and Cofins are scheduled to be abolished in 2027 under Brazil’s tax reform (Constitutional Amendment 132/2023), but the controversy remains live for existing claims subject to the five-year statute of limitations.
- The central tension is whether the tobacco sector’s inflated tax base — a legislative device used to tax tobacco heavily without raising stated rates — is a “presumed” base subject to Theme 228 refund rights, or a fixed statutory value insulated from those rights.
Why It Matters
The financial stakes are substantial. Brazil’s cigarette retail market is large, and if the First Section ultimately holds that retailers may strip out the statutory multiplier and recalculate contributions using the raw shelf price, nearly every cigarette sale in recent years would generate a refund claim — potentially hundreds of millions of reais. Conversely, a ruling for the government would confirm that Congress can deploy inflated tax bases as a fiscal tool for regulatory (extrafiscal) purposes without triggering constitutional refund guarantees, even when the actual transaction value is far below the base used for collection.
The case also tests the outer boundaries of Theme 228 and of Article 150 § 7 of the Brazilian Constitution. The Supreme Court’s Theme 228 precedent established that tax-substitution overpayments must be refunded when the actual taxable event is smaller than presumed; the STJ must now decide whether that guarantee reaches a sector where the “presumed” base is not an estimate of future retail prices but rather a deliberate legislative amplification of them. The answer will shape how Brazilian courts handle analogous extrafiscal tax schemes going forward.
