Background
Brazil’s PIS (Social Integration Program contribution) and Cofins (Social Security Financing contribution) are collected from cigarette and cigarillo retailers through a “forward substitution” mechanism: manufacturers, importers, and wholesalers pay these contributions in advance on behalf of the downstream retailer. The tax base for that advance payment is not simply the retail price but is instead an inflated figure produced by applying a statutory multiplier to the government-set table price — 291.69% of the table price for PIS and a coefficient of 3.42 times the table price for Cofins. The standard rates (0.65% for PIS; 3% for Cofins) are then applied to those inflated bases. The legislature deliberately chose this inflated-base technique, rather than higher rates, as a tool of selective taxation designed to discourage tobacco consumption on public-health grounds.
Petitioner Mercado Derner Ltda., a retail seller of cigarettes and cigarillos, argued that whenever its actual sales price falls below the statutory tax base — which is virtually always the case, since even selling at the full government-mandated table price generates a tax base that is roughly three times that price — it is entitled to a refund of the excess PIS and Cofins paid by its upstream substitutor. It relied on the Supreme Court’s binding precedent under Theme 228 of general repercussion (RE 596.832, decided 29 June 2020), which holds that a refund is due whenever the actual taxable event occurs at a value lower than the presumed base used for advance collection. The Federal Regional Court of the Fourth Region denied relief, holding that the cigarette sector’s regime involves a legally fixed base, not a “presumed” one, and that Theme 228 therefore does not apply.
The Brazilian federal government (União) cross-argued that the multipliers carry an extrafiscal purpose and cannot be stripped out to produce a lower effective base, and that because retail prices are legally mandated retailers have no authority to sell below the table price in any event. The Second Panel of the STJ had already ruled against retailers on identical grounds in REsp 2.135.871 and REsp 2.199.044 (both decided 16 October 2025), holding that a legally fixed base is distinct from a presumed base and that applying Theme 228 would nullify the regime’s public-health objectives.
The Court’s Holding
The First Section of the STJ, acting unanimously on the report of Justice Maria Thereza de Assis Moura, did not resolve the merits. Instead, it designated REsp 2215075 and REsp 2177940 as representative test cases under the repetitive-appeals procedure (arts. 1.036–1.037 of the Code of Civil Procedure and arts. 256–256-X of the STJ’s internal rules), which requires the full First Section — the court’s plenary tax chamber — to issue a single binding ruling applicable to all similar pending cases.
The court defined the precise legal question to be resolved: whether the difference between the amount advanced using the statutory multiplier or coefficient applied to the table price and the amount that would be due based on the price actually charged in the retail transaction must be refunded to cigarette and cigarillo retailers with respect to PIS and Cofins. The First Section simultaneously ordered the nationwide suspension of all pending individual and collective proceedings — at every level of the federal judiciary — that turn on this same question, pending the binding ruling.
The court acknowledged the tension between Theme 228’s refund guarantee and the government’s extrafiscal-purpose arguments but reserved judgment on that tension for the merits phase. It also noted that PIS and Cofins are scheduled for abolition in 2027 under Constitutional Amendment 132/2023, but found the controversy remains live because claims and credits arising under the current regime will continue to be litigated until prescription cuts off further disputes.
Key Takeaways
- The STJ has formally elevated the cigarette PIS/Cofins refund dispute to binding repetitive-case status, meaning the First Section’s eventual merits ruling will be mandatory precedent for all Brazilian courts.
- All pending individual and collective cases on this issue — nationwide, at any court level — are stayed immediately pending that binding ruling.
- The core legal tension is whether the statutory multiplier/coefficient that inflates the PIS and Cofins base constitutes a “presumed” tax base triggering Theme 228 refund rights, or a legally fixed base that forecloses any refund claim regardless of actual sales price.
- A prior Second Panel ruling (REsp 2.135.871, Oct. 2025) already went against retailers; the designation of this issue to the full First Section creates the opportunity to either confirm or overrule that precedent with binding effect.
- Even though PIS and Cofins will be extinguished in 2027, the ruling will govern all claims arising before that date until the five-year prescription period runs.
Why It Matters
The outcome will determine whether every cigarette and cigarillo retailer in Brazil is entitled to recover a portion of the PIS and Cofins prepaid on its behalf through the substitution chain — a potential refund that, given the size of the multipliers (291.69% and 3.42×), could represent a very substantial portion of the taxes collected from the sector over the prescription period. The aggregate fiscal exposure for the government could be significant given the number of tobacco retailers nationwide and years of collection under the inflated-base methodology.
The case also raises a broader structural question about the constitutionality and limits of using an inflated tax base — rather than elevated rates — as an instrument of selective or extrafiscal taxation. If the STJ ultimately holds that Theme 228 applies, it may signal that legislatures cannot achieve unrecoverable selective taxation by manipulating the base rather than the rate. The ruling will be closely watched by practitioners in the tobacco, fuel, and other sectors that use similar substitution-plus-multiplier mechanisms for indirect tax collection.
