PIS/COFINS recovery.
5 retroactive years.

Theme 69 — Thesis of the Century (STF RE 574.706)

Decided by the STF on March 15, 2017, with the modulation of effects set on May 13, 2021. Unanimously, the STF held: “ICMS does not form part of the calculation base for the levy of PIS and COFINS”.

Legal logic

PIS and COFINS are levied on gross revenue. ICMS is a tax collected by the seller but belonging to the State — it does not form part of the taxpayer’s assets and is therefore not revenue.

2017 modulation — retroactivity window

The modulation established that the decision produces effects from March 15, 2017 — except for companies that had already filed a lawsuit before that date, which keep the right to recover earlier amounts subject to the five-year statute of limitations.

Typical financial impact

A reduction of approximately 1.5% to 2.5% of gross revenue over the last 5 years. For a company with BRL 100M of annual revenue, the typical recoverable credit is BRL 7.5M to BRL 12.5M over 5 years.

Theme 779 — Essential inputs (STJ REsp 1.221.170)

The STJ, in a 2018 repetitive appeal, held that the concept of input for a PIS/COFINS credit must be interpreted by the essentiality and relevance to the taxpayer’s economic activity. It ended years of restrictive interpretation by the Federal Revenue.

Items creditable today (after Theme 779)

• Fuel in an owned transport/distribution fleet
• PPE (Personal Protective Equipment) mandated by law
• Technical training of the operational team
• Software essential to the operation (not merely administrative)
• Freight between establishments of the same company
• Packaging materials not directly integrated into the product

Companies with a high volume of such expenses that do not yet take the credit have significant recoverable credit — an analysis of SPED-Contribuições over the last 60 months reveals the opportunities.

Unused single-phase credits

Fuels, medicines, cosmetics, auto parts and beverages have a single-phase PIS/COFINS regime — the manufacturer/importer collects the tax for the entire chain, and the following links (wholesalers, retailers) resell at a zero rate.

Frequent errors that generate recoverable credit:

• A wholesaler/retailer paid PIS/COFINS on the resale of a single-phase product (it should have been zero)
• Incorrect tax classification (wrong NCM code, product not classified as single-phase)
• Imported single-phase products with double taxation on entry and exit

For sectors with a high volume of single-phase products, an audit can reveal 1-3% of revenue in recoverable credits over the last 5 years.

Theme 118 — Exclusion of ISS (on trial at the STF)

A direct extension of Theme 69. The STF is deciding whether ISS, like ICMS, must be excluded from the PIS/COFINS base. There are favorable decisions in regional courts, and the scenario at the STF tends to favor the taxpayer (following the logic of Theme 69).

Preventive strategy

Companies that file a lawsuit before the STF’s modulating decision typically preserve the right to amounts prior to the modulation. It is a frequent strategic window in theses still in dispute — filing even before consolidated case law can preserve a retroactivity that a later modulation eliminates.

Benefited sectors

Service providers with a high ISS burden (law, engineering, architecture, pure-service IT, private healthcare, private education) — sectors where ISS of 5% on revenue accumulates significantly over PIS/COFINS.

Critical pre-Reform window (until Dec 2026)

PIS and COFINS will be extinguished in January 2027 for most sectors, replaced by CBS. After the regime ends, recovery is still legally possible (the five-year statute of limitations continues), but operationally more complex because:

• The collection system is different (CBS via the Steering Committee)
• SPED-Contribuições stops being filed
• The conversion of retroactive credits into CBS requires specific regulation from the Steering Committee
• The Federal Revenue will have less infrastructure to process PIS/COFINS PER/DCOMP

It is advisable to accelerate diagnoses and filings during 2026. Each month of delay means losing a full monthly period to the statute of limitations + the risk of post-Reform operational complexity.
