The SPA is signed and the purchase price allocation is complete. The Brazil Pillar Two work is not. For a Brazilian target, Article 21 of RFB Normative Instruction 2,228/2024 generally removes acquisition-method accounting changes from the financial accounting result used under the Brazilian rules, while Article 91 of the original instruction, read with its 2025 amendment, addresses a target joining or leaving an MNE group through a direct or indirect ownership-interest transfer. The first close can fail when accounting, local tax and group tax teams carry one number across those tests without carrying its legal meaning.
Goodwill changes Brazil deal economics only after the team separates three objects: accounting goodwill created by the PPA, Brazilian tax goodwill and the carrying values used for GloBE. Deferred tax requires the same discipline. Articles 49 and 52 filter measurement and recapture; Article 91 can disregard acquisition-related deferred tax in its own fact pattern. A 34% accounting measurement is not automatically a GloBE covered-tax amount.
Start with deal form, not with the PPA label
| Deal path | What usually changes | First GloBE question | Brazil first-close evidence |
|---|---|---|---|
| Share deal | The target changes group; its separate-entity books may not record the consolidation PPA. | Does the target join through a controlling ownership-interest transfer under OECD Article 6.2 and Brazilian Article 91? | Final SPA, before-and-after ownership chart, acquisition date and separate-versus-consolidated ledger map |
| Asset deal | The buyer records acquired assets and liabilities; tax basis may or may not follow accounting value. | Does OECD Article 6.3 govern the transferred assets and liabilities, and what does Brazilian domestic tax law recognise? | Asset schedule, legal transfer documents, tax-basis roll-forward and purchase-accounting entries |
| GloBE reorganisation | Assets and liabilities move in a transaction that may receive continuity treatment. | Do the Article 6.3 reorganisation conditions and any non-qualifying gain or loss apply? | Reorganisation steps, consideration, seller tax treatment and opening carrying values |
| Historical business combination | Old acquisition accounting remains embedded in current reporting packages. | Does the narrow pre-1 December 2021 exception in Brazilian Article 21 apply, with all its conditions? | Acquisition-date file, original PPA, historical ledgers and proof that unadjusted values cannot be reconstructed with reasonable accuracy |
“M&A” is not a tax classification. A share purchase, an asset purchase and a tax-neutral reorganisation can produce similar-looking PPA schedules but different GloBE starting points. The OECD’s 2025 Consolidated Commentary uses Article 6.2 for entities joining or leaving a group and Article 6.3 for transfers of assets and liabilities. That distinction should be documented before the accounting close, not reconstructed during a filing review.
Article 92, as rewritten by RFB Normative Instruction 2,245/2024, adds another boundary. It treats an acquisition or disposal of a controlling interest as an asset-and-liability transfer only when the target’s jurisdiction—or, for a tax-transparent entity, the jurisdiction of the assets—both treats the interest transfer in the same or a similar way and imposes a Covered Tax on the target or the disposing entity by reference to the specified tax-basis difference. Its current sole paragraph then says the article does not apply to Constituent Entities “localizadas no Brasil”; for a tax-transparent entity, it separately refers to assets located in Brazil. That is why a team cannot convert Article 91 into a universal “share deal rule” or Article 92 into a universal “asset deal rule”. Facts, location and domestic treatment still control the path.
Four ledgers must survive the foreign-HQ-to-Brazil handoff
- 1 — Deal and PPA
- Object: consideration, identifiable assets and liabilities, fair-value uplifts and accounting goodwill. Question: where was the price allocated at the acquisition date? Handoff: SPA, valuation report, PPA workbook, policy memo and deferred-tax calculation.
- 2 — Financial reporting
- Object: separate-entity, local-consolidation and group-consolidation entries. Question: which entry reached which reporting package and period? Handoff: trial balance, consolidation journals, account mapping and approved note support.
- 3 — Brazilian domestic tax
- Object: IRPJ/CSLL basis, tax goodwill, attributes and legal deductibility requirements. Question: what consequence does the implemented legal structure support? Handoff: entity-level tax-basis schedule, legal steps, valuation support and tax memo.
- 4 — GloBE and Brazil QDMTT
- Object: GloBE Income or Loss and Adjusted Covered Taxes by jurisdiction. Question: which accounting effects are retained, removed, recast or monitored? Handoff: rule-by-rule bridges, elections, deferred-tax subledger, source trail and reviewer sign-off.
The handoff breaks when a label travels without its provenance. “Goodwill” may mean the residual asset in consolidated accounts, a domestic tax attribute supported by Brazil-specific requirements, or shorthand for an acquisition adjustment that is absent from the GloBE carrying value. Those are not interchangeable balances.
Foreign headquarters should ask Brazil for both the separate-entity and consolidation views. The 2025 OECD Commentary notes that a share acquisition often leaves the target’s individual position unchanged while fair-value adjustments appear at consolidation. A GloBE bridge built only from the consolidated PPA can therefore import adjustments the rules require the group to remove. TaxUp’s Pillar Two glossary provides the English terminology used across the four ledgers.
Brazilian Articles 21, 49, 52, 52-C, 78, 91 and 92 do different jobs
| Provision | Decision it informs | Condition or exception | Do not conclude | Official text |
|---|---|---|---|---|
| Article 21 | Whether acquisition-method changes are considered in the accounting result used by the Brazilian GloBE rules | The operative anchor is “não serão consideradas, em regra”. The exception requires a pre-1 December 2021 business combination, the changes to be reflected in the Article 10 financial statements for the first fiscal year in which the group enters scope in that jurisdiction, and insufficient information to reconstruct unadjusted values with reasonable accuracy; paragraph 2 addresses related deferred tax. | “PPA never enters Pillar Two.” | Original instruction and 2025 amendment |
| Article 49 | How deferred-tax expense is recast, excluded or otherwise adjusted | Paragraph 1 has two branches: where the applicable tax rate is below 15%, it starts from the deferred-tax expense in the financial statements; otherwise it is “recalculada à alíquota de 15%”. Other paragraphs and Articles 50–51 still apply. The amended paragraph 3 and paragraph 5(I) generally apply from 2026, with a group option for 2025. | “Every Brazilian DTA or DTL enters at 15%” or “34% goes straight into covered taxes.” | Original instruction, IN 2,245/2024 and IN 2,282/2025 |
| Article 52 | Whether a previously included DTL must be recaptured | The liability must have been included in the deferred-tax adjustment, must not fall within the non-recapturable category and “não tenha sido pago ou revertido nos cinco Anos Fiscais subsequentes”. The rewritten Article 52 applies from 2025; Articles 52-A–52-J generally apply from 2026, with a group option for 2025. | “Every DTL is automatically recaptured after five years.” | Original instruction and 2025 recapture amendment |
| Article 52-C | Which items may be combined in a Recapture Aggregate | Non-amortising intangible assets, including goodwill, “não poderão ser incluídos em um Agregado para Recaptura”. This is a tracking-level restriction, not a universal exemption from recapture; Article 91 goodwill receives separate treatment because its related DTA/DTL is already disregarded there. | “Goodwill can never create a recapture issue.” | IN 2,282/2025 |
| Article 78 | How acquisition-method asset values enter the Eligible Tangible Assets component of the substance-based income exclusion | For that specific Article 77 calculation, it considers “alterações nos valores dos ativos decorrentes da aplicação do método de aquisição”. It does not import those changes into every other GloBE calculation. | “Article 21 removes acquisition-method values for every Pillar Two purpose.” | Original Article 78, IN 2,245/2024 caput rewrite and IN 2,282/2025 sole-paragraph amendment |
| Article 91 | How a target joining or leaving the group through an ownership-interest transfer is treated | It starts from “valor contábil histórico”. Specified acquisition adjustments—including “ágio por rentabilidade futura (goodwill)”—and related deferred tax are disregarded. Incisos VI and VII separately govern continuity and recapture tracking for pre-existing deferred-tax balances. | “Article 91 governs every business or asset acquisition” or “every acquired DTA/DTL disappears.” | Original Article 91 and 2025 amendment |
| Article 92 | When an acquisition of a controlling interest in a foreign entity is treated as an acquisition of assets and liabilities | The foreign jurisdiction must both treat the interest transfer in the same or a similar way and impose a Covered Tax on the target or the disposing entity by reference to the stated tax-basis difference. The current sole paragraph says the article “não se aplica a Entidades Constituintes localizadas no Brasil” and separately addresses Brazilian assets of a tax-transparent entity. | “Article 92 applies to the Brazilian target used in the worked example below.” | IN 2,245/2024 rewrite and RFB consolidated text |
Article 2 of Law 15,079/2024 states the objective as “tributação mínima efetiva de 15%”. It does not authorise a shortcut of multiplying ordinary accounting profit by a mechanical rate. The instruction supplies the adjustments, conditions and definitions needed to move from the accounts to the Brazilian minimum-tax calculation.
For the broader calculation and scope, use TaxUp’s Brazil OECD Pillar Two guide. This article owns the narrower decision: what the deal team must preserve so the buyer can build the first-close bridges without confusing acquisition accounting with domestic tax or GloBE.
The PPA can reconcile while the Pillar Two bridge still fails
| Line | Amount | Equation or role | Boundary |
|---|---|---|---|
| Consideration transferred | 200.00 | Assumed purchase consideration | Not an actual price or transaction |
| Identifiable net assets before PPA | 100.00 | Pre-acquisition accounting amount | Does not determine Brazilian tax basis |
| Gross fair-value uplift | 40.00 | Illustrative acquisition adjustment | Depends on valuation and accounting policy |
| Assumed tax-basis uplift | 0.00 | Model assumption | Actual basis depends on structure and law |
| Temporary difference | 40.00 | 40.00 − 0.00 | Only as sound as the two input bases |
| Accounting measurement rate | 34% | Assumed solely for the accounting DTL | Not a GloBE numerator rate |
| Deferred tax liability | 13.60 | 40.00 × 34% | Illustrative accounting measurement |
| Goodwill before DTL effect | 60.00 | 200.00 − 100.00 − 40.00 | One disclosed accounting view |
| Net assets after DTL | 126.40 | 100.00 + 40.00 − 13.60 | Restricted to model assumptions |
| Goodwill after DTL | 73.60 | 200.00 − 126.40 | Not presented as universal accounting consensus |
| Independent goodwill check | 73.60 | 60.00 + 13.60 | Checks arithmetic only |
| Consideration check | 200.00 | 126.40 + 73.60 | Checks arithmetic only |
This model deliberately adopts the view that recognising the DTL reduces identifiable net assets and increases residual accounting goodwill. Gabriel Bez-Batti analyses that relationship in his 2025 IBDT article, while recording disagreement among accounting authors. The model selects a transparent path so the equations can be checked; it does not declare that path mandatory for every PPA.
The first-close file should retain each input rather than only the final 73.60. If the tax-basis uplift changes, if the accounting rate changes or if the transaction is not the share-deal fact pattern assumed here, both the accounting bridge and the GloBE bridge must be rebuilt.
The first-close GloBE bridge uses a different carrying value
| Line | Amount | Treatment tested | Boundary |
|---|---|---|---|
| Legal assumptions | The target is a Constituent Entity located in Brazil and joins the group through a direct or indirect ownership-interest transfer. The PPA charge and DTL movement arise solely from acquisition-method changes. Pre-existing deferred-tax balances are segregated. Article 92 therefore does not apply to the target in this exercise. Change any fact and the bridge must be rebuilt. | ||
| Pretax result after PPA charge | 80.00 | Deliberately pretax diagnostic starting point | Not net income or GloBE Income |
| PPA depreciation/amortisation charge | 8.00 | Item tested under the acquisition rule | Reversal depends on classification |
| Diagnostic reversal | +8.00 | Removes the charge in the stated scenario | Not valid outside those premises |
| Pretax diagnostic income base | 88.00 | 80.00 + 8.00 | Proxy, not jurisdictional GloBE Income |
| Closing temporary difference | 32.00 | 40.00 − 8.00 | Assumes unchanged tax basis |
| Closing DTL | 10.88 | 32.00 × 34% | Accounting measurement, not automatic GloBE tax |
| Candidate current covered taxes | 10.00 | Simplified current-tax input | Not the complete numerator |
| Acquisition-related DTL movement | −2.72 | 10.88 − 13.60 | Related solely to the same uplift in this model |
| Taxes before Article 91 adjustment | 7.28 | 10.00 + (−2.72) | Not a reportable ETR numerator |
| Adjustment to disregard the benefit | +2.72 | − (−2.72) | Do not apply to every acquisition or pre-existing DTL |
| Candidate covered taxes after adjustment | 10.00 | 7.28 + 2.72 | Other covered-tax adjustments remain omitted |
| Minimum rate in sensitivity | 15% | Mechanical reference | Not an isolated application of the statute |
| Diagnostic ETR | 11.3636% | 10.00 ÷ 88.00 | Diagnostic sensitivity only |
| Mechanical gap | 3.6364 pp | 15% − 11.3636% | Not an Additional CSLL rate |
| Mechanical amount | 3.20 | 88.00 × 3.6364% | Not Additional CSLL payable |
The arithmetic reconciles: the DTL falls from 13.60 to 10.88, producing a −2.72 movement; the model removes that acquisition-related benefit under its stated Article 91 premises, returning candidate taxes from 7.28 to 10.00. The resulting 11.3636% is intentionally labelled diagnostic because the model omits the substance-based income exclusion, safe harbours, elections, allocation rules, other current and deferred-tax adjustments and the full Brazilian jurisdictional perimeter.
The OECD’s 2025 Commentary on Article 6.2.1(c) uses the “historical carrying value” and says the associated acquisition DTL “should be disregarded for GloBE purposes” in that fact pattern. Article 6.3 can lead to a different path for asset transfers or reorganisations. A consolidated PPA schedule therefore cannot serve as the only first-close ledger.
Three acquired deferred-tax buckets need three different treatments
- Acquisition-method DTA/DTL. Article 91(1)(II) disregards deferred-tax balances arising from the accounting changes covered by the acquisition rule.
- Other pre-existing DTA/DTL. Subject to its conditions, Article 91(VI) carries transferred balances into the acquiring MNE Group “da mesma forma e na mesma extensão” as if that group had controlled the Constituent Entity when they arose.
- A pre-existing DTL already included in the deferred-tax adjustment. Article 91(VII) supplies a specific seller-side and buyer-side recapture rule rather than treating the balance as newly created purchase accounting.
Under Article 91(VI)–(VII) of the original instruction, read with the 2025 amendment, the disposing MNE Group treats a previously included target DTL “como revertidos” and does not recapture it in that group. The acquiring MNE Group treats the same liability “como surgidos no ano da aquisição” for recapture tracking. If a later recapture reduces Covered Taxes, the effect belongs in the recapture year; the fifth preceding fiscal year is not recalculated. These are rules for the two MNE Groups, not necessarily labels for the legal seller and purchaser named in the SPA.
The worked model above does not quantify that transferred-balance track. It assumes pre-existing deferred tax has been segregated and models only the −2.72 movement arising from the stated acquisition-method uplift. Applying that adjustment to a transferred pre-existing DTL would violate the model’s own premises.
Accounting goodwill, tax goodwill and GloBE carrying values are not synonyms
| Object | Where it lives | What creates it | What it does not prove |
|---|---|---|---|
| Accounting goodwill | Acquisition accounting and consolidated financial statements | Residual after consideration is allocated to identifiable assets and liabilities under the applicable accounting standard | Brazilian tax deductibility or GloBE carrying value |
| Brazilian tax goodwill | Domestic IRPJ/CSLL tax records | Legal form, allocation support, corporate steps and the domestic rules applicable to the implemented facts | Recognition as accounting goodwill or inclusion in GloBE Income |
| GloBE carrying value | GloBE workpapers and deferred-tax subledger | The Model Rules and applicable domestic QDMTT provisions, including Articles 6.2/6.3 and Brazilian Articles 21/91/92 | The value shown in group purchase accounting |
Calling all three “goodwill” hides the reconciliation the buyer actually needs. In the OECD example supporting Article 6.2.1(c), purchase-accounting adjustments may exist in consolidated statements while historical carrying values continue for GloBE. In Brazilian tax, deductibility follows a separate body of law and evidence. Neither one can be inferred from the other.
A real filing shows why labels are only the beginning. In its 2025 Form 20-F filed with the SEC, Afya presents, in thousands of Brazilian reais, deferred-tax liabilities of R$25.293 million labelled “tax benefit from tax deductible goodwill” and R$28.274 million labelled “fair value remeasurements on business combinations”. The filing is an accounting-label bridge, not a GloBE calculation. It shows why the IAS 12/CPC 32 exception for deferred taxes arising from Pillar Two income taxes cannot be read as a blanket removal of ordinary acquisition DTA/DTL; it does not establish whether either Afya balance is included, recast, excluded or recaptured under GloBE. That conclusion would require asset-level accounting basis, tax basis, GloBE carrying value and movement tracing.
This is also where tax and finance should agree on naming conventions. The PPA workbook should identify each adjustment, the legal entity that owns it, the reporting layer where it appears, the related tax basis and the corresponding GloBE carrying value. A single account code without those fields is not a controlled bridge.
The 2026 M&A simplification is a safe-harbour rule, not an automatic Brazilian amendment
| Question | Section 3.4.2 answer | Deal-team consequence |
|---|---|---|
| Where does it sit? | Inside the OECD Simplified ETR Safe Harbour in the January 2026 Side-by-Side Package. | Do not describe it as a freestanding amendment to the full GloBE rules or to Brazil’s instruction. |
| What difference does it address? | The M&A-related difference between accounting carrying values and GloBE carrying values in the tested jurisdiction. | Maintain asset- and liability-level records even if the safe harbour is expected to apply. |
| When can the safe harbour be available? | Paragraph 196 requires implementing and QDMTT-only jurisdictions to make the framework available for fiscal years beginning on or after 31 December 2026. Paragraph 197 permits optional earlier availability for fiscal years beginning on or after 31 December 2025, but only through one of its stated jurisdictional routes. | Verify the fiscal year, Brazil’s domestic adoption and the relevant taxing-rights and election conditions before relying on an early path. |
| What technical conditions apply to the M&A simplification? | Subject to all stated conditions, including unchanged tax basis for the affected assets/liabilities and corresponding deferred tax accrued at no less than the minimum rate; goodwill has a specific treatment. | A tax-basis step-up or missing/low-rate deferred tax can switch the path back to normal adjustments. |
| What happens to initial deferred tax? | The accrual arising from the M&A transaction is not included in Simplified Taxes, while qualifying reversals are treated under the section’s mechanism. | Separate initial recognition from later movement in the subledger. |
| Does it erase the full-rules file? | No. The OECD expressly preserves the need for sufficient records if full GloBE calculations are required in a later year. | Do not discard the historical PPA bridge after a safe-harbour year. |
| Does it automatically change Brazil’s QDMTT? | No automatic domestic-law conclusion follows from the OECD publication alone. | Check the Brazilian text and effective incorporation before using it in an Additional CSLL return. |
The official Side-by-Side Package, sections 3.4.2 and 7.4, labels the measure “M&A Simplification” and can materially reduce adjustments where its eligibility conditions are met. Paragraphs 196–197 place the Simplified ETR Safe Harbour on a general fiscal-year path beginning on or after 31 December 2026, with an optional earlier path beginning on or after 31 December 2025 only where one of the stated jurisdictional conditions is met. Section 3.4.2 also contains a specific treatment for goodwill: under common accounting standards, an initial DTL is not recorded for goodwill arising in a business combination, so impairment or amortisation can otherwise distort the simplified ETR. The section prescribes additions or exclusions depending on whether a corresponding deferred-tax reversal exists at the required rate, while paragraph 69 says it “does not relieve the MNE Group” of the stated recordkeeping obligation.
Two caveats belong in every board memo. First, this M&A simplification is part of the Simplified ETR Safe Harbour. Second, OECD administrative guidance operates within the common approach; it does not rewrite Brazil’s RFB instruction by itself. In the consolidated text currently displayed by the RFB, Article 1(1) refers to OECD documents approved “até julho de 2025” (through July 2025), while Article 1(5) permits subsidiary use of later interpretive materials when “expressamente adotados” (expressly adopted) by the RFB. The January 2026 package postdates that cut-off. A group should therefore document which rule set it is applying, for which fiscal year and on what domestic authority, rather than treating section 3.4.2 as automatically operative for the Additional CSLL.
Deferred-tax recapture needs a subledger, not a year-five surprise
| Check | Evidence | Decision risk |
|---|---|---|
| Was the DTL included? | Prior-year Total Deferred Tax Adjustment / Brazilian equivalent and rule citation | An amount excluded at acquisition cannot be recaptured as though it had been included. |
| Was it transferred with the target? | Article 91(VI)–(VII) classification, disposing-group history and acquisition-year opening record | A previously included DTL is deemed reversed for the disposing group and treated as arising in the acquisition year for the acquiring group’s recapture tracking. |
| Which carrying value created it? | Accounting, tax and GloBE carrying values tied to one asset or liability | Monitoring the book DTL can be wrong where GloBE requires a different carrying value. |
| Did it reverse or get paid? | Annual roll-forward with journal, tax return and settlement support | A balance-only review misses partial reversals and settlement events. |
| Does an exception or aggregation restriction apply? | Classification under OECD Article 4.4.5 and Brazilian Articles 52-A–52-J, including Article 52-C, with supporting facts | A Recapture Exception Accrual can change the result; Article 52-C’s bar on placing specified intangibles in a Recapture Aggregate controls tracking level but is not a blanket recapture exemption. |
| Has five years elapsed? | Relevant inclusion or Article 91(VII) acquisition year, reversal expectation and period-by-period control | Using a generic deal date instead of the legally assigned origin year can misstate timing. |
The 2025 OECD Commentary on Articles 4.4.4 and 4.4.5 makes the logic conditional: recapture applies to a DTL determined by reference to the relevant GloBE carrying value unless an exception or applicable election changes the treatment. The Brazilian text likewise requires prior inclusion, non-payment or non-reversal and absence of the non-recapturable classification. Article 52-C additionally prevents specified items—including non-amortising intangibles and goodwill—from entering a Recapture Aggregate; it does not say every related DTL is non-recapturable.
The practical response is an acquisition-specific deferred-tax subledger from day one. At minimum it needs asset or liability ID, legal entity, jurisdiction, origin, accounting basis, tax basis, GloBE carrying value, measurement rate, rule relied upon, inclusion year, expected reversal, actual reversal and owner. If those fields do not exist at first close, the year-five review will become an expensive reconstruction.
Historical acquisitions require proof, not a blanket grandfathering label
- Qualify the event. Preserve the original accounting conclusion and acquisition file; an old asset purchase is not automatically a business combination.
- Prove the acquisition date. Confirm that accounting control transferred before 1 December 2021; signing date alone may not answer that question.
- Locate the first in-scope statements. Show that the acquisition-method changes were reflected in the Article 10 financial statements for the first fiscal year in which the group entered scope in that jurisdiction.
- Attempt the reconstruction. Search historical trial balances, PPA journals, asset and intangible registers and system archives; inconvenience is not insufficient information.
- Document reasonable accuracy. Record the data-gap test, what was searched and the reviewer’s conclusion before invoking the exception.
- Separate the deferred tax. Preserve opening DTA/DTL by source and later movement; do not merge acquisition-created balances with pre-existing balances.
Article 21’s date is a gateway, not the whole test. The exception applies to a business combination with an acquisition date before 1 December 2021 only when the remaining statutory conditions are also satisfied—including reflection of the changes in the Article 10 financial statements for the first fiscal year in which the group enters scope in the jurisdiction. For a foreign buyer acquiring a Brazilian group with a long deal history, the diligence request should therefore cover predecessor systems and archived consolidation entries, not only the current trial balance.
The 2025 OECD Commentary also says Article 6.2.1(c) can reach pre-transition-year transactions. That makes historical carrying values a live compliance issue even when the deal team that produced the original PPA has moved on. Data retention belongs in the purchase agreement and transition-services plan.
The SPA should allocate Pillar Two evidence before closing
- Historical accounting data: require usable separate and consolidated trial balances, PPA journals and account mappings so historical GloBE carrying values and Article 21 can be tested.
- Tax-basis warranty: require asset-level Brazilian tax basis, elections, amortisation history and known disputes to keep domestic tax goodwill separate from the accounting PPA.
- Deferred-tax schedule: require opening DTA/DTL by origin, rate, expected reversal and reporting layer so acquisition-created and pre-existing balances cannot be merged.
- Pillar Two cooperation: allocate reasonable post-close access and support for GIR/QDMTT data requests because a filing cycle can mature after operational control transfers.
- Control of elections and filings: name who decides, reviews and signs straddle-period positions; an election can change both buyer and disposing-group workstreams.
- Change and true-up mechanism: define how measurement-period PPA changes, audit adjustments and later information update the bridge without a silent overwrite.
These are drafting topics, not model clauses. The appropriate language depends on deal structure, governing law, materiality and the allocation of tax risk negotiated by the parties. The decision point is earlier: if the SPA is silent about source data and post-close cooperation, the buyer can inherit a filing obligation without the records needed to defend it.
The same principle applies to transaction models. If a purchase-price model includes a tax benefit from Brazilian goodwill but no cost for maintaining a GloBE carrying-value ledger, the forecast is incomplete. Deal economics include the timing, evidence and reversibility of the benefit, not just the nominal deduction.
Named owners turn the first close into a repeatable control
Corporate / M&A legal
Owns: final form, acquisition date, perimeter and executed steps. Evidence: closing binder and before/after structure chart. Challenge: Brazil tax legal and group tax.
Accounting / valuation
Owns: PPA, useful lives, impairment assumptions and consolidation entries. Evidence: approved valuation report and journal package. Challenge: controller and auditor.
Brazil domestic tax
Owns: tax basis, IRPJ/CSLL treatment, tax goodwill and attributes. Evidence: entity-level legal and tax-basis memo. Challenge: Brazil tax legal.
Group Pillar Two
Owns: article classification, GloBE income and covered-tax bridges, elections and recapture map. Evidence: versioned workpapers with source IDs. Challenge: group tax director and controller.
Data / systems
Owns: entity, account, currency and period lineage. Evidence: frozen extracts, transformation log and total reconciliation. Challenge: controller and group reporting.
CFO or tax governance committee
Owns: materiality, adopted position and residual risk. Evidence: decision memo with assumptions and contrary evidence. Challenge: governance designated by the group.
No single team “owns” the answer by itself. Legal qualifies the transaction. Accounting explains the PPA. Brazil tax supports domestic basis. Group tax applies the GloBE filters. The controller proves that versions and totals reconcile. Governance approves the remaining uncertainty.
A transfer-pricing adjustment can also change jurisdictional profit without automatically becoming the same GloBE adjustment in the same period. TaxUp’s transfer pricing and Pillar Two guide owns that bridge; the acquisition file should cross-reference it rather than blend the two workstreams into one unexplained true-up.
Doctrine identifies the fault lines; official text decides the filing position
| Reading | Useful contribution | Limit | How to use it |
|---|---|---|---|
| Gabriel Bez-Batti, RDTI Atual, vol. 14 (2025) | Connects Brazilian business-combination accounting and tax treatment to ETR effects before and after a critical restructuring event; exposes disagreement over DTL and goodwill. | The conclusions are conditional and the paper predates later Brazilian and OECD developments. | Use it to frame questions and contrary views; verify the current legal answer in the official texts. |
| Guido Vinci, Flávia Cavalcanti and Karolina Rosen, International Tax Journal 51(4) (2025) | Organises the analysis around acquisition, reorganisation and post-reorganisation stages and examines Brazilian goodwill amortisation, purchase accounting and deferred tax. | It is identified doctrine, not Brazilian law or OECD guidance; its discussion of later goodwill-related DTL includes interpretive uncertainty. | Use it as a transaction-stage checklist and disclose where a view remains unsettled. |
| OECD 2025 Consolidated Commentary | Explains Articles 6.2 and 6.3, historical carrying values, acquisition-related deferred tax and recapture mechanics. | It does not replace the enactment and effective-date analysis of Brazil’s QDMTT. | Use it to interpret the coordinated GloBE framework alongside the current Brazilian text. |
| OECD 2026 Side-by-Side Package, sections 3.4.2 and 7.4 | Adds the M&A Simplification within the Simplified ETR Safe Harbour and states the general and optional early applicability dates in paragraphs 196–197. | It is not a freestanding Brazilian domestic rule and does not remove full-rules recordkeeping. | Test safe-harbour eligibility, fiscal-year timing and domestic incorporation separately. |
| Afya 2025 Form 20-F | Shows separate accounting labels and balances for tax-deductible goodwill and business-combination fair-value remeasurements. | Does not disclose an asset-level GloBE treatment for those balances. | Use as a real reporting bridge, never as proof of inclusion, recasting, exclusion or recapture. |
The two articles are valuable because they show where transaction practice creates ambiguity. Bez-Batti highlights a possible ETR reduction after Brazilian tax deductions for goodwill and fair-value surplus under the scenario he studies, while also preserving a contrary accounting view. Vinci, Cavalcanti and Rosen examine whether a DTL connected with later tax amortisation of goodwill can enter Adjusted Covered Taxes and expressly leave room for a restrictive Brazilian tax-authority interpretation.
That uncertainty belongs in the decision memo. A defensible first close should distinguish the official rule, the adopted interpretation, the contrary interpretation, the amount exposed and the evidence that would cause the group to change course. TaxUp’s international tax practice can coordinate that Brazil-to-HQ file with the group’s accounting and tax teams.
Frequently asked questions on Brazil Pillar Two acquisitions
| Question | Short answer | Next proof |
|---|---|---|
| Does every PPA adjustment disappear? | No. Start with Article 21 and its historical exception, but preserve Article 78’s specific tangible-asset rule and then test Articles 91/92 and OECD Articles 6.2/6.3. | Deal form, acquisition date, calculation purpose and reporting layer |
| Is a 34% accounting DTL included at 34%? | Not automatically. Article 49 applies recasting, exclusions and other adjustments. | Tax rate, basis, origin and applicable branch of Article 49 |
| Is every DTL recaptured after five years? | No. Prior inclusion, reversal/payment, Article 52-C tracking limits, exception status and Article 91(VII) acquisition-year treatment must be tested. | Deferred-tax subledger and Articles 52–52-J / 91(VII) / OECD 4.4 analysis |
| Does the 2026 M&A Simplification amend Brazil automatically? | No. It sits inside the Simplified ETR Safe Harbour; domestic incorporation must be checked. | Fiscal year, safe-harbour election and current Brazilian authority |
| Is 3.20 in the model the tax due? | No. It is a mechanical sensitivity on an incomplete hypothetical base. | Full jurisdictional calculation and all omitted adjustments |
| Can the PPA workbook be the GloBE ledger? | No. It is a source, but GloBE carrying values and rejected adjustments need their own controlled bridge. | Separate GloBE ledger with source and rule IDs |
Does every PPA adjustment disappear from the Brazil Pillar Two calculation?
No. Article 21 provides a general rule for acquisition-method changes and a narrow exception for qualifying pre-1 December 2021 business combinations. For the specific Article 77 Eligible Tangible Assets calculation, Article 78 considers acquisition-method asset-value changes. Articles 91 and 92 address different transaction fact patterns, while OECD Articles 6.2 and 6.3 distinguish entity acquisitions from transfers of assets and liabilities.
Is a deferred tax liability measured at 34% included in GloBE at 34%?
Not automatically. The accounting rate measures the book balance. Article 49 of RFB Normative Instruction 2,228/2024 applies its own branches, recasting, exclusions and related adjustments before a deferred-tax amount can affect Adjusted Covered Taxes.
Is every deferred tax liability recaptured after five years?
No. The liability must first have been included in the relevant deferred-tax adjustment, remain unpaid or unreversed for the applicable period and fall outside the non-recapturable or Recapture Exception categories and any applicable election. Article 52-C limits which items may enter a Recapture Aggregate; it is not a blanket exemption. For a previously included target DTL, Article 91(VII) treats it as reversed for the disposing MNE Group and as arising in the acquisition year for the acquiring MNE Group’s recapture tracking.
Does the OECD 2026 M&A Simplification automatically apply to Brazil’s Additional CSLL?
No automatic conclusion follows from the OECD publication alone. Section 3.4.2 is part of the Simplified ETR Safe Harbour. Paragraph 196 provides the general fiscal-year path beginning on or after 31 December 2026; paragraph 197 allows an optional earlier path beginning on or after 31 December 2025 only through one of its stated jurisdictional conditions. The group must establish eligibility and verify how and when the guidance has effect under the current Brazilian QDMTT framework.
Is the 3.20 amount in the model the Additional CSLL payable?
No. It is a diagnostic sensitivity on a hypothetical, incomplete pretax base. The model omits safe harbours, the substance-based income exclusion, elections, allocation rules, other tax adjustments, recapture and the complete jurisdictional perimeter.
Can the group use the PPA workbook as its GloBE acquisition ledger?
No. The PPA is an essential source, but it does not identify every GloBE carrying value or document every excluded adjustment. The group needs a separate, versioned bridge that maps each PPA line to accounting layer, Brazilian tax basis, GloBE treatment and rule citation.

The Brazilian rule set was reconciled against the original instruction and five amending instructions: 2,245/2024, 2,259/2025, 2,282/2025, 2,319/2026 and 2,329/2026. Only NIs 2,245/2024 and 2,282/2025 affect provisions used in this acquisition cut. NI 2,245/2024 rewrote the Article 78 caput and Article 92; NI 2,282/2025 amended the Article 78 sole paragraph and added Articles 52-A–52-J. The OECD and doctrinal materials were used for their stated functions; doctrine never substitutes for the official text.
The numerical model contains no client or public-company data. Its falsification condition is explicit: if the target does not join through the ownership-interest transfer assumed, Article 92 applies, the tested DTL does not arise solely from acquisition accounting, the Article 91(VI)–(VII) pre-existing-balance track is not segregated, or any omitted item changes the numerator or denominator, the 2.72 adjustment and 3.20 sensitivity must not be reused.
