Transfer pricing in Brazil after Law 14,596/2023: the arm's length principle in domestic law, OECD-aligned methods, R$15m and R$500m documentation tiers, and an enforcement cycle that is only now beginning.
The federal tax and customs administration inside the Ministério da Fazenda. Filings run through the e-CAC portal; normative acts sit in the RFB's own Normas/SIJUT database.
RFB Normas (SIJUT); IN RFB 2.161/2023Converted from Provisional Measure 1.152/2022. It governs the IRPJ and CSLL bases and ended Brazil's fixed-margin regime. Election into 2023 was available and irrevocable.
Lei 14.596/2023, arts. 1º and 47Published 29 September 2023 and amended since, notably by IN RFB 2.246/2024 and IN RFB 2.249/2025 on commodity registration. The annexes carry the working mechanics: country-risk adjustments, multi-year averaging, interquartile computation.
IN RFB 2.161/2023, arts. 1º–81, Anexos I–VIArt. 46 repealed arts. 18 to 23 and art. 24 §2º of Lei 9.430/1996 (item VI) and art. 50 of Lei 8.383/1991 (item V). Of Lei 4.506/1964 it repealed only art. 52 and alíneas d to g of the parágrafo único of art. 71 (item III) — the caput of art. 71 and alíneas a to c survive. The 1%–5% caps fell with art. 74 of Lei 3.470/1958 and arts. 12 and 13 of Lei 4.131/1962 (items I and II). IN 1.312/2012 was revoked from 1 January 2024. Fixed margins survive only in open years and legacy disputes.
Lei 14.596/2023, art. 46, I–III, V–VI; IN 2.161/2023, art. 80, I, alínea aControlled transaction terms must be those unrelated parties would set in comparable transactions; non-compliance triggers the adjustment machinery in IN art. 48.
Lei 14.596/2023, art. 2º; IN 2.161/2023, art. 2ºThey interpret and fill gaps but cannot override the Law, the IN or other RFB acts. Argue OECD paragraphs as persuasive, never as controlling authority.
IN RFB 2.161/2023, art. 1º, §4ºDirect or indirect influence capable of producing non-arm's-length terms, then deemed relationships: control, branches, affiliates, consolidation, 25% profit entitlement, 20% common shareholding, family links to the third degree.
Lei 14.596/2023, art. 4º and §1ºPrivileged tax regimes are caught on the same footing. Law 14.596/2023 art. 40 rewrote arts. 24 and 24-A of Lei 9.430/1996.

Lei 14.596/2023, art. 11, §§1º–2º; IN 2.161/2023, arts. 33–34, 45IN art. 45 §1 points to income-based valuation where no reliable comparables exist; the taxpayer must document valuation criteria and critical assumptions.
IN RFB 2.161/2023, art. 45, §§1º–2ºThe OECD profile records no preference, but the regulation is more directive: search the tested party's own geographic market first and adjust for material differences using the country-risk guidance in Anexo II.
IN RFB 2.161/2023, art. 23, §§1º–4º and Anexo IIApplies to external database sets under PRL, MCL and MLT, and only where relaxation improves range reliability. Related-party transactions are never comparable. Secret comparables may not be used.
IN RFB 2.161/2023, arts. 20 §4º, 21 §3º, 22 parágrafo únicoCurrent or preceding year plus the two before it, entered as a weighted arithmetic mean. Reject comparables with a negative weighted average or losses in more than one period. Generally inappropriate for PIC.

IN RFB 2.161/2023, art. 66; Lei 14.596/2023, art. 35Immaterial means it does not compromise the reliability of the arm's length result. But fail to report or substantiate group consolidated revenue and the R$5m maximum applies automatically.
IN RFB 2.161/2023, art. 66, §§2º, 4º–5ºThe auditor must offer it before assessing. Conditional on cooperation, reasonable efforts and coherent criteria — and late or missing Master or Local File filing is deemed a failure of reasonable efforts.

Lei 14.596/2023, art. 38; OECD profile, January 2026Treaty-agreed outcomes must be implemented even on matters outside the transfer pricing law. Governed by IN RFB 1.846/2018 as amended. Every Brazilian treaty carries a MAP article.
Lei 14.596/2023, arts. 39 and 43; IN 2.161/2023, art. 77Lei Complementar nº 227/2026 cut the impugnação and voluntary appeal deadlines from 30 calendar days and added a 20 December–20 January procedural recess. Judicial review remains available.
Decreto 70.235/1972 (as amended by LC 227/2026)IN SRF 243/2002 art. 12 §11 held unlawful for inventing PRL-60 concepts absent from Lei 9.430/1996 art. 18(II). It concerns the repealed regime but shows the STJ policing regulatory overreach — a template for challenging IN 2.161/2023.
STJ, AREsp 511.736-SP, Informativo nº 754Outside the interquartile range and median, alternative statistics are available when implementing treaty-agreed results and in the specific consultation process.
IN RFB 2.161/2023, art. 47, §7º; Lei 14.596/2023, art. 16, §5ºNo provision in the Law or the IN, and no RFB act adopting it identified as at August 2026. Brazil has nonetheless indicated it will respect covered-jurisdiction outcomes.

IN RFB 2.228/2024 regulates it; IN RFB 2.319/2026 reportedly requires DCTFWeb reporting by the sixth month after fiscal year end — verify before relying on the date.
Lei 15.079/2024, arts. 2º, 4º and 43It does not amend the transfer pricing rules, but it sharpens the tension IN 2.161/2023 art. 51 already flags: adjustments do not flow automatically to import tax bases.
IN RFB 2.326/2026; IN 2.161/2023, art. 51CY2024 was the first mandatory year and documentation first fell due in late 2025. The RFB's 2026 plan leans on data cross-referencing, alerts and self-regularisation, with commodities and supply chains an early focus.
RFB Relatório Anual da Fiscalização 2025-2026The RFB consulted publicly on both drafts in August 2024 with an announced 1 January 2025 effective date. Further rules for TPG Chapters VII–X special transactions are also in preparation.
RFB public consultation, August 2024; OECD profile, January 2026Art. 44 catches amounts also deductible for another related party, amounts not taxable to the recipient, and funding arrangements producing either result.
Lei 14.596/2023, art. 44; IN 2.161/2023, art. 78Brazil spent a quarter of a century as the world's most conspicuous transfer pricing outlier. Fixed statutory margins, formulaic import and export price ceilings, and an explicit refusal to run comparability analysis put the country outside the OECD consensus and generated chronic double taxation for inbound groups. Lei nº 14.596 of 14 June 2023 ended that. Article 2º writes the arm's length principle into domestic law in terms recognisable in any OECD jurisdiction: the terms and conditions of a controlled transaction must be those unrelated parties would establish in comparable transactions. Article 47 brought the statute into force on 1 January 2024, with an irrevocable election available for 2023, and article 46 dismantled the old machinery — articles 18 to 23 and article 24 §2º of Lei nº 9.430/1996, article 50 of Lei nº 8.383/1991, article 52 of Lei nº 4.506/1964 together with alíneas d to g of the parágrafo único of its article 71, and the 1% to 5% royalty and technical assistance deduction caps in article 74 of Lei nº 3.470/1958 and articles 12 and 13 of Lei nº 4.131/1962. Note the precision of the repeal: the caput of article 71 of Lei nº 4.506/1964 and its alíneas a to c remain on the statute book.
The detail sits in Instrução Normativa RFB nº 2.161 of 28 September 2023: eighty-one articles and six annexes, since amended, most notably by IN RFB nº 2.246/2024 and IN RFB nº 2.249/2025 on commodity registration. Read the annexes. They are not appendices in any decorative sense — Anexo II carries the country-risk comparability adjustment guidance, Anexo III the multi-year averaging mechanics, Anexo V the computation of the median and interquartile range. Much of what practitioners will actually argue about is buried there rather than in the operative articles.
The status of the OECD Guidelines is precisely calibrated and worth understanding before an audit rather than during one. IN article 1º §4º makes the 2022 Guidelines a subsidiary source for interpretation and gap-filling. Later OECD amendments count only once the RFB expressly approves them, and the Guidelines cannot be applied where they conflict with the Law, the IN or other RFB normative acts. A Chapter I paragraph is therefore persuasive when the domestic text is silent or ambiguous, and worthless when the domestic text says otherwise. Counsel who lead with the Guidelines rather than with the statute will be corrected.
Scope is broad. The rules reach Brazilian legal entities on the real, presumed and arbitrated profit regimes, and extend to branches and business units constituting an economic or professional unit even where not formally incorporated. The related-party test in article 4º begins with substance — direct or indirect influence capable of producing terms that diverge from arm's length — then deems relationships by control, consolidation, a 25% entitlement to profits or liquidation assets, 20% common shareholding, and family links to the third degree by blood or affinity. Separately, the rules apply to any counterparty, related or not, resident where income is untaxed or taxed at a maximum rate below 17%, or operating under a privileged regime.
Article 11 provides the five OECD methods under Portuguese acronyms — PIC, PRL, MCL, MLT and MDL — plus a residual category for other methodologies producing an arm's length result. There is no formal hierarchy, but the most appropriate method standard carries a heavy thumb on the scale: where reliable price information from comparable uncontrolled transactions exists, PIC is treated as most appropriate unless another method is demonstrably better suited. That is not a neutral tie-break. A taxpayer running TNMM on a transaction where quoted or internal price data exists should expect to defend the choice on the record, and should build that defence into the Local File rather than improvising it later.
The other-methods route carries a double burden under IN article 34: document why none of the five prescribed methods applies or yields reliable results, and why the alternative is more appropriate. IN article 45 §1 then names income-based valuation, and discounted cash flow in particular, as generally most appropriate for hard-to-value intangibles and equity interests without reliable comparables — a useful concession, but one requiring the valuation criteria and critical assumptions to be set out in full.
On benchmarking, the domestic regulation is more directive than the OECD profile suggests. The profile records no preference between domestic and foreign comparables. IN article 23 says something firmer: comparables should normally be identified in the tested party's own geographic market because economic circumstances differ materially between markets, with non-domestic sets permitted where no reliable domestic information exists and reasonably accurate adjustments can be made. Where the two readings diverge, follow the regulation. In practice a pan-Latin American or European set imported wholesale into a Brazilian file needs an articulated reason and a country-risk adjustment referenced to Anexo II.
Three screening rules repay attention. First, the independence filter runs at 20% shareholding, relaxable to 25% where fewer than four comparables survive all filters under PRL, MCL or MLT and only where relaxation improves range reliability; related-party transactions are never comparable, and secret comparables cannot be used against a taxpayer. Second, multi-year data is standard for MLT with external comparables — three years, entered as a weighted arithmetic mean, with comparables rejected where the weighted average is negative or losses appear in more than one period — but generally inappropriate for PIC. Third, the interquartile range is not automatic. Under article 47 it applies only where comparability uncertainties remain that cannot be precisely identified, quantified or adjusted; where none remain, the full range governs, and a single comparable of the highest reliability rules the interquartile range out altogether. Land outside the appropriate range and the median is imposed.
Documentation is tiered on the value of controlled transactions in the preceding calendar year, measured before transfer pricing adjustments. At R$500,000,000 or more, a full Local File under IN articles 59 and 60. From R$15,000,000 to just under R$500,000,000, a simplified Local File under article 61, covering the entities involved, the type and value of each transaction, the method used, the comparables and resulting ranges, the reasons for those choices, and any adjustments made in the year. Below R$15,000,000, no Local File — and no Master File either. Article 57 §3º states the trap plainly: exemption from filing is not exemption from applying the rules.
The Master File, the Arquivo Global, follows Annex I of Chapter V in substance: organisation chart with geographic locations, the group's principal profit drivers, functional analysis, supply chain for the five largest products or services plus anything above 5% of group turnover, intragroup service arrangements, restructurings and acquisitions, intangibles strategy and key contracts, financing policy and treasury centres, a list of unilateral APAs and rulings affecting cross-border income allocation, and the latest consolidated statements.
Within the Local File, the 80% coverage rule applies separately to four categories — imports of goods, exports of goods, imports of services, exports of services — with commodities, intangibles, business restructurings, cost sharing and financial operations reported in full whatever their size. Filing is by Digital Process in the e-CAC portal, one process per calendar year, with corrections attached to the existing process rather than filed fresh, 15 MB per PDF and 150 MB per compressed file. The deadline is three months after the ECF transmission deadline, which for calendar-year taxpayers lands on the last business day of October; for CY2024 a transitional rule pushed it to the last business day of 2025.
Two further obligations run in parallel. Controlled commodity transactions must be registered in the Registro de Transações com Commodities by the tenth day of the month after the contract is executed, whatever form the contract takes, whether or not PIC is used, and again on renegotiation or extension — the operative wording of IN article 64 is that given by IN RFB nº 2.249/2025, which also carried a transitional §6º allowing contracts signed in January and February 2025 to be registered up to 31 March 2025. And the ECF itself carries dedicated transfer pricing records in Bloco X — X360 through X375E — which must be completed by every taxpayer with controlled transactions, including those exempt from the Local File entirely; record X370 must capture all controlled transactions, including those the 80% rule leaves out. Country-by-country reporting rides in Bloco W of the same return, at R$2,260,000,000 for a Brazilian ultimate parent and EUR 750,000,000 where the parent is abroad. Master files in English or Spanish need translating only on request; other languages need a simple Portuguese version.
The penalty architecture in IN article 66 is calibrated to compel filing rather than to raise revenue. Late Master or Local File filing costs 0.2% per calendar month or fraction of gross revenue for the period. A filing that fails the prescribed requirements costs 3% of gross revenue — striking, since a defective file is punished far more heavily than a merely late one. Inaccurate, incomplete or omitted Master File information costs 0.2% of the group's prior-year consolidated revenue. Obstruction, or failure to produce requested information during an audit, costs 5% of the transaction value as priced by the authority. All are floored at R$20,000 and capped at R$5,000,000, and the CbC penalties in IN 1.681/2016 article 11 mirror the same grid.
There is genuine relief for immaterial defects: the Master File penalty does not apply to duly evidenced formal errors or to information whose absence does not compromise the reliability of the arm's length result. The converse is unforgiving — fail to report or substantiate the group's consolidated revenue and the R$5,000,000 maximum applies automatically.
The most valuable provision in the regime is IN article 67. Where the auditor disagrees with the taxpayer's computation, the auditor must, before assessing, serve a Termo de Constatação giving thirty days to amend the ECF and DCTF for the transfer pricing adjustments alone. Pay the resulting tax with late charges inside that window and no ex officio penalty attaches. The conditions are behavioural: no action against binding administrative guidance, cooperation, reasonable efforts to comply, and coherent, reasonably justifiable criteria. Critically, late or missing Master or Local File filing is itself deemed a failure of the reasonable efforts condition. A group that files late has not merely bought a fine; it has forfeited its penalty shield for the whole audit.
Article 34 §1º supplies the enforcement backstop. Where the taxpayer does not supply the information needed to delineate the transaction or run the comparability analysis, the authority may allocate to the Brazilian entity every function, asset and risk attributed to the foreign party for which there is no reliable evidence of actual performance, use or assumption, and may adopt reasonable estimates. Thin documentation of an overseas principal does not produce a stalemate; it produces a Brazilian principal.
Timing matters for where we now stand. CY2024 was the first mandatory year and the first documentation packages fell due in late 2025. The RFB reported roughly R$233 billion of assessments in 2025 and framed its 2026 plan around data cross-referencing, alerts and self-regularisation. The first genuine audits of the new regime are only now beginning, with commodities and multinational supply chains flagged early.
Advance certainty is the weakest limb of the regime. Article 38 authorises a specific transfer pricing consultation covering method and financial indicator selection, comparables and comparability adjustments, significant comparability factors and critical assumptions. The commercial terms are set: R$80,000 for an accepted request, payable within fifteen business days of acceptance or the request lapses; R$20,000 to extend; validity up to four years, extendable by two; rollback available where facts and circumstances were the same. Annulment is retroactive where the request rested on erroneous, false or misleading information, and a change in critical assumptions invalidates the ruling from the date of change.
Two caveats matter. The mechanism is unilateral only — the statute makes no provision for bilateral or multilateral APAs, notwithstanding that the OECD profile records them as available through the treaty network. Advisers should treat bilateral certainty as something to be negotiated under a treaty, not claimed under domestic law. And the implementing Normative Instruction, consulted on publicly in August 2024 with an announced 1 January 2025 start, could not be confirmed as published as at August 2026. The programme is statutorily authorised and operationally unproven.
MAP is in better shape. Article 39 requires the authority to revise an assessment ex officio to implement a treaty-agreed result, including on matters outside the transfer pricing law, and IN article 77 amended IN RFB nº 1.846/2018 to make that revision mandatory and to disapply the general 360-day administrative response deadline. Statistical measures beyond the interquartile range and median are permitted when implementing treaty outcomes and in the APA process. Since downward adjustments are otherwise prohibited outright, MAP is the only route to relief where Brazil has over-taxed.
Domestically, transfer pricing assessments follow Decreto nº 70.235/1972: impugnação to a DRJ, voluntary appeal to CARF, special appeal to the Câmara Superior on divergent decisions, with judicial review beyond. Lei Complementar nº 227/2026 tightened the clock materially — twenty business days for both the impugnação and the voluntary appeal, replacing thirty calendar days — and introduced a procedural recess between 20 December and 20 January. Diarise accordingly. On limitation, the general CTN five-year rules apply, with a live and unresolved question whether article 150 §4º runs from the taxable event or article 173(I) from the first day of the following year. The leading judicial authority remains the STJ's decision in AREsp 511.736-SP, which struck down article 12 §11 of IN SRF nº 243/2002 for inventing PRL-60 concepts absent from the statute. It concerns the repealed regime, but the principle travels: a Normative Instruction that adds to the Law is vulnerable.
Brazil enacted Pillar Two through Lei nº 15.079 of 27 December 2024, creating an Additional CSLL designed as a Qualified Domestic Minimum Top-up Tax delivering a 15% minimum effective rate for constituent entities of groups at EUR 750,000,000 or more in two of the four preceding fiscal years. It took effect from 1 January 2025 and is regulated by IN RFB nº 2.228/2024, with an August 2025 public consultation to internalise the June 2024 and January 2025 Administrative Guidance and further updates announced in June 2026; IN RFB nº 2.319/2026 reportedly requires the Additional CSLL to be reported in DCTFWeb by the sixth month after the jurisdiction's fiscal year end, which should be verified before diarising.
The interaction with transfer pricing is direct. A QDMTT computed on GloBE income makes the Brazilian effective rate sensitive to every transfer pricing adjustment, and a primary adjustment increasing Brazilian taxable income may change the top-up calculation as well. Groups modelling the two regimes in separate spreadsheets will find their transfer pricing planning producing unintended Pillar Two consequences.
The customs interface is the second pressure point. IN article 51 confirms that spontaneous and compensatory adjustments do not automatically flow through to other tax bases, including import taxes, which are determined under their own legislation. IN RFB nº 2.326/2026, published 20 May 2026, does not amend the transfer pricing rules but incorporates World Customs Organization valuation materials into Brazilian law, making the tension more visible. In practice a customs auditor can read the importer's transfer pricing study and use it to challenge declared import values, while the taxpayer cannot symmetrically use a downward transfer pricing adjustment to reduce them.
Two gaps remain open. Brazil has not implemented Amount B — nothing in the Law or the IN adopts the simplified and streamlined approach, though Brazil has indicated it will respect the outcome where a covered jurisdiction applies it, and the RFB holds a general simplification power under article 37 that it has so far used only for low value-adding services. And further regulation is pending for the special transactions in TPG Chapters VII to X, alongside the APA instruction.
Start with the filing calendar, because the penalty regime punishes lateness structurally rather than proportionately. Three dates drive everything: the tenth of each month for commodity registrations in the RTC, the last business day of July for the ECF carrying Bloco X and Bloco W, and roughly the last business day of October for the Master and Local Files. Miss the third and the article 67 self-correction shield goes with it — a consequence that dwarfs the fine.
Second, build the file to survive reproduction. IN articles 62 and 63 require documents to be organised contemporaneously and, on request, require the taxpayer to rerun its comparable searches on its own systems in the presence of the auditor. That means preserving search strategies, date-stamped screens, filter logs and, above all, the reasons for each manual rejection. A benchmarking study whose search cannot be replicated two years later is a study the auditor is entitled to disbelieve.
Third, write the method narrative defensively. Given PIC's presumptive status, any file using a margin-based method on goods, and especially on commodities, should state affirmatively why reliable comparable price information was unavailable or inferior. Where an other method or a DCF is used, meet the double test in IN article 34 in terms.
Fourth, treat compensatory adjustments as a documentation project rather than a year-end entry. They must be symmetric and definitive in both sets of books, evidenced by debit or credit notes stating nature and amount, ratified by a declaration from the foreign counterparty's legal representative and attested by the Brazilian representative, booked permanently for the transaction year, and completed by the ECF filing date. They are unavailable entirely for counterparties in low-tax jurisdictions or privileged regimes. Since downward adjustments are otherwise prohibited outside MAP, the compensatory route is the only self-help available — and it fails on paperwork more often than on substance.
Fifth, evidence the foreign side of the transaction. Article 34 §1º allocates unevidenced functions, assets and risks to Brazil.
