PIS and Cofins will be abolished on 1 January 2027, and the stock of credits your company carries to that date will be frozen as of the December 2026 EFD-Contribuicoes filing — the snapshot that migrates into the new system. That is why 2026 is the last year to review the credit base and recover what was left behind: late credits never taken, inputs reclassified under STJ Theme 779, and balances that lapse month by month. The Federal Revenue Service has already flagged around R$ 44 billion in discrepancies and is telling companies to fix their bookkeeping before the cut-off. A company that reaches 2027 with an incomplete base carries a smaller, more fragile credit into the CBS; one that reviews now turns a right that was about to lapse into cash.
- 2026 is the last window: the balance that migrates to the CBS is the one declared in the December 2026 EFD-Contribuicoes filing.
- Late credits: what was never taken can still be recovered — subject to the five-year statute of limitations, which runs month by month.
- The ruler is STJ Theme 779: an input is defined by essentiality or relevance. That is where most of the recoverable credit lives.
- Not every credit becomes cash: only refundable ones (exports, untaxed revenue, presumed credits); the “ordinary” domestic-market credit only offsets the CBS.
- R$ 44 billion under review: auditing your own base before being flagged is both defence and offence.
Why the deadline is now
The urgency is not rhetorical. It comes from three dates and one number, all converging on the 2026 cut-off.
1 January 2027: the end of PIS and Cofins
The Brazilian tax reform (Constitutional Amendment 132/2023 and Complementary Law 214/2025) abolishes PIS and Cofins on 1 January 2027 and replaces them with the CBS. The credit balance does not vanish (LC 214/2025 preserves it), but the way to build it ends together with the contributions. Anything not correctly assessed and booked by the turn can no longer be assessed under the PIS/Cofins rules.
The December 2026 snapshot
The Federal Revenue Service has confirmed that credit use in the new system will run through PER/DCOMP Web, which automatically pulls the balance reported in the December 2026 EFD-Contribuicoes filing. In other words: the December 2026 bookkeeping is the photograph that crosses over to the CBS. A credit that should be there and is not will not migrate on its own afterwards. That is why the review work has to finish before that period is closed, not in 2027.
The R$ 44 billion the tax authority has already flagged
On 3 June 2026 the Federal Revenue Service published an official note on the transition and disclosed that it had identified discrepancies of around R$ 44 billion in credits declared in EFD-Contribuicoes. The action is guidance, not assessment: taxpayers will be called to regularise their bookkeeping. But the message is clear: the credit base is going under review, and an inconsistent balance is a balance at risk of disallowance.
The credit-stock picture
| Metric (Federal Revenue Service, 3 Jun 2026) | Figure |
|---|---|
| Companies holding PIS/Cofins credits | ~100,000 |
| Total credit stock | ~R$ 140 billion |
| Companies with flagged discrepancies | ~12,000 |
| Value of the discrepancies | ~R$ 44 billion |
| Companies with a balance below R$ 100k | 70% |
| Companies with a balance below R$ 1m | 90% |
The read for the tax decision-maker: there is a huge, scattered stock, and the tax authority is already looking at it. Reviewing your own base before being flagged is the move that is defensive and offensive at once.
What “recovering PIS/Cofins credits” really means
Recovering is not “finding forgotten money”. It is rebuilding, with evidence, credits the company was entitled to and never took — within the rules on deadlines and proof.
Late credits: what was left behind
A late credit is a non-cumulative PIS/Cofins credit that could have been taken in a past period and was not. The tax authority allows it to be taken later, provided the statute of limitations is respected and the bookkeeping is corrected (with an EFD amendment where needed). It is exactly the kind of credit that tends to sit outside the base: an expense classified as “use and consumption” that was actually an input, an item disallowed on a restrictive reading, a poorly apportioned split between taxed and untaxed revenue.
The ruler for what generates credit: the input concept
The question that defines almost every recovery is a single one: what counts as an input. And the ruler is not the restrictive one the tax authority used in the past — it is the Superior Court of Justice’s.
Essentiality and relevance (STJ Theme 779)
In Theme 779/780 (REsp 1,221,170/PR, 1st Section, published 24 Apr 2018), the STJ held that the input concept for PIS/Cofins credit purposes must be measured by essentiality or relevance — the indispensability or importance of the good or service to the taxpayer’s economic activity. It is a broad concept, reaching far beyond what physically touches the product. Most of the recoverable credit lives precisely there: items essential to the operation that were never credited out of a conservative reading.
A living ruler, applied case by case
The thesis keeps yielding. Courts apply the Theme 779 input concept case by case, generally requiring technical proof — a report evidencing the item’s essentiality to the activity. It is not museum case law: it is a ruler applied day to day, and the recoverable credit shows up exactly when the conservative accounting classification is tested against operational reality, item by item.
The five-year deadline: the limitation that runs month by month
Recovery has a window. The right to a late credit is subject to a five-year limitation period.
How the five years are counted
The five-year period runs from the first day of the month following the one in which the credit could originally have been assessed — a position consolidated by the tax authority in Cosit Ruling No. 355/2017, based on article 1 of Decree No. 20,910/1932. In practice, this means that with every month that passes the company loses the oldest tip of its recoverable stock. A company that only looks in 2027 will have let almost a full year of credits lapse — and will also have lost the simple PIS/Cofins ruler for building them.
The “until 2031” controversy
There is a reading that the balance could be used “until 31 Dec 2031” (five years counted from the abolition). It is a defensible thesis for part of the balance, but the literal text of article 378, I, of LC 214/2025 preserves “the running of the period” already in course — that is, the five years counted from the original assessment, not from the abolition. We treat this as a thesis, not a fact: planning recovery on the assumption of 2031 is putting the credit at risk. The safe working horizon is the 2026 cut-off.
The three exits for the credit (and the catch)
Once recovered and booked, the credit can leave through three routes, set out in article 378 of LC 214/2025. But not every credit goes through every route, and that is where many companies get the maths wrong.
Offsetting the CBS itself
The most direct route. The PIS/Cofins balance may offset the CBS due from 2027. Article 382 also creates a priority rule: the old PIS/Cofins balance must be consumed before current CBS credits, because it is the closest to lapsing.
Offsetting other federal taxes
The balance may, in theory, offset corporate income tax (IRPJ), social contribution on profits (CSLL), IPI and other federal taxes — but only where the credit is already refundable under the current PIS/Cofins legislation, in the logic of PER/DCOMP offsetting. And here is the part that misleads.
The catch of the “ordinary” balance
Not every credit turns into cash or offsets IRPJ/CSLL freely. The nature of the credit defines what is possible.
Refundable credits: exports, untaxed revenue and presumed credits
Credits tied to export revenue, revenue untaxed in the domestic market and presumed credits are refundable and may offset other federal taxes. Those, yes, can become cash or settle other obligations.
The domestic-market balance that only offsets the CBS
The “ordinary” credit (tied to taxed domestic-market sales), by contrast, generally only serves to offset the contribution itself (and, after 2027, the CBS). It does not become a cash refund and does not offset IRPJ/CSLL freely. Projecting the whole stock as “immediate cash” is the most common reading error. Serious recovery separates, from the outset, what is refundable from what merely reduces a future tax.
Cash refund
For refundable credits, a cash refund can be requested through PER/DCOMP Web.
Monetary restatement: STJ Theme 1,003 and Precedent 411
A book credit is, as a rule, not restated, but there are relevant exceptions. Under Theme 1,003 (REsp 1,767,945/PR, 1st Section, published 6 May 2020), restatement of the refund applies after the 360-day window the tax authority has to analyse the request has run out (article 24 of Law 11,457/2007). And STJ Precedent 411 — established for IPI crediting — guarantees restatement where there is unlawful resistance by the administration to taking the credit, a logic the court extends to non-cumulative book credits. Filing early and tracking the 360 days stops being a detail: it is what preserves the real value of the credit.
Where the hidden credit usually sits
In practice, recovery concentrates in a few recurring spots. Each is worth checking.
Fixed assets and depreciation that crosses 2027
PIS/Cofins credits taken via depreciation or amortisation of fixed assets continue to be taken as a presumed CBS credit after 2027 (article 380 of LC 214/2025). The practical risk: if the asset is sold before the end of the appropriation, the remaining instalments are lost. There is also the case of 2026 invoices whose capitalisation only completes in 2027, a situation that needs case-by-case analysis to avoid losing credit at the turn.
Opening inventory and the 9.25% presumed credit
Article 381 provides a presumed credit on the opening inventory on 1 January 2027 for companies in the cumulative regime, under tax substitution or single-phase taxation. The rate is 9.25% on the inventory value — against the 3.65% of the current regime-change credit (Laws 10,637/2002 and 10,833/2003) — taken in 12 instalments and only against the CBS. It is a credit that is born at the turn and that many companies forget to inventory.
Inputs reclassified under Theme 779
The biggest pocket tends to sit in reviewing conservatively classified expenses. Freight between establishments, packaging, essential services, production-line maintenance items: in light of non-cumulativity and Theme 779, many become credit. It is item-by-item tax-base review work, with documentary support.
How to recover and protect before December 2026
Recovery done right is a methodical project, not an isolated request in the system. There are five fronts.
Step 1 — Map the stock and the running of the deadlines
Map the entire credit balance and, for each block, identify the original assessment date and how long is left before it lapses. That is what sets the order of priority: the oldest credit first.
Step 2 — Review the base under Theme 779
Re-analyse expenses and contracts to identify uncredited inputs, applying the essentiality-or-relevance test. This is where most of the recoverable credit sits, and where the need for proof is greatest.
Step 3 — Correct the EFD-Contribuicoes
Amend the bookkeeping to incorporate the identified credits and cure the inconsistencies (the same ones the tax authority is flagging in the R$ 44 billion). It is the step that makes the credit formally exist before the December 2026 photograph, connected to digital bookkeeping (SPED/EFD).
Step 4 — File and monitor
Formalise the requests through PER/DCOMP Web and track the tax authority’s 360-day window, the trigger for monetary restatement under Theme 1,003. A credit filed and monitored converts; a credit merely booked may sleep.
Step 5 — The tax decision-maker’s checklist
| Front | Control question | Why it matters |
|---|---|---|
| Stock | Do I know the total balance and the age of each block? | Sets priority and limitation |
| Inputs | Have I reviewed the base under the essentiality test (Theme 779)? | Where the biggest credit is |
| EFD | Does the Dec 2026 bookkeeping reflect the real credit? | It is the photo that migrates |
| Nature | Have I separated what is refundable from what only offsets the CBS? | Avoids a wrong cash forecast |
| Fixed assets | Have I mapped the depreciation crossing 2027? | Avoids loss on disposal |
| Risk | Do I have documentary support for each credit? | Shields against disallowance |
The risks of doing nothing (and of doing it wrong)
Inaction has a cost, but haste without method does too.
Disallowance of inconsistent credits
The R$ 44 billion already flagged shows the path of the audit. A balance without support is the first to fall. Reviewing before being questioned is what separates a solid credit from a fragile one.
Lapse of old balances
Every month without action is a tip of credit that lapses. There is no retroactive recovery of what passed the five-year mark.
Structures without documentary support
Recovering credit without proof of essentiality (no report, no traceability in the bookkeeping) is building a liability, not an asset. The favourable case law (Theme 779) is precisely the one that demands technical evidence case by case.
How TaxUp runs the recovery
The work starts with mapping the stock and reading the limitation, moves through reviewing the base under Theme 779 with documentary support, corrects the EFD before the 2026 cut-off and ends in a monitored filing through PER/DCOMP Web. It is the junction of tax-credit recovery with a reading of the tax reform, because the same credit recovered today is the one that will offset the CBS tomorrow.
“Recovering PIS/Cofins credit in 2026 is not hunting for lost money. It is recognising, with evidence, a right the company already held and carrying it intact into the new system. What lapses this year does not come back, and what is not in the December EFD does not migrate on its own.”

Frequently asked questions
Do PIS/Cofins credits end together with the contributions in 2027?
No. LC 214/2025 (article 378) preserves the credit balance: it remains valid and may offset the CBS, offset other federal taxes or be refunded, depending on the nature of the credit. What ends is the way to build it under the PIS/Cofins rules, from 1 January 2027.
Why recover now and not later?
Because the balance that migrates to the CBS is the one declared in the December 2026 EFD-Contribuicoes filing, and because a late credit lapses five years from the original assessment. Every month of 2026 that passes without review is credit that lapses and that may fall outside the photograph crossing into the new system.
What is a late PIS/Cofins credit?
It is a non-cumulative credit that could have been taken in the past and was not. It can be recovered later, subject to the five-year period and to amending the bookkeeping.
How do I know what counts as an input?
By the test the STJ set in Theme 779: essentiality or relevance of the good or service to the economic activity. It is a broad concept, reaching items essential to the operation even if they do not physically form part of the product, and it usually requires technical evidence.
Can I turn the whole credit balance into cash?
Not necessarily. Only refundable credits (tied to exports, untaxed revenue and presumed credits) become cash or offset other federal taxes. The “ordinary” domestic-market balance, as a rule, only offsets the contribution itself and, after 2027, the CBS.
How long can I use the balance after 2027?
There is controversy. The literal text of article 378 preserves the original period (five years from the assessment); part of the doctrine argues five years from the abolition (2031). To be safe, treat the 2026 cut-off as the working deadline and do not plan recovery on the assumption of 2031.
