The Brazilian tax reform, currently in the process of being regulated after the approval of Constitutional Amendment No. 132/2023, promotes structural changes in the consumption tax system, with the replacement of taxes such as PIS, Cofins, ICMS, and ISS with new modelsbased on the IBS (Tax on Goods and Services) and the CBS (Contribution on Goods and Services). Although these changes are concentrated in indirect taxation, many companies have questioned whether there will be impacts or interactions with the Transfer Pricing rules recentlyadopted in Brazil. In general, Transfer Pricing rules — reformulated by Law No. 14,596/2023 and aligned with the OECD’s arm’s length principle — continue to focus on the correct allocation of results between related parties in different jurisdictions, with direct effects on the calculation of IRPJ and CSLL. The tax reform, on the other hand, has as its main objective the reorganization of taxation on consumption. Thus, under a strictly normative analysis, the two topics remain in different fields of tax legislation. However, from an economic and operational perspective, some interactions may arise. The adoption of a dual VAT system (IBS and CBS) tends to increase transparency and tax neutrality in value chains. This can influence the structuring of operations between companies in thesame group, especially in distribution models, service provision and centralization of functions in certain entities. Changes in the form of consumption taxation may lead multinational groups to review operational flows, which can indirectly impact transfer pricing policies. In addition, companies that carry out intra-group imports and exports may need to assess whether any changes in tax costs or price formation in the domestic market alter the economic assumptions used in their comparability studies. While transfer pricing methods remainfocused on analyzing margins and market conditions between independent parties, structural changes in the economy may require updates to benchmarking analyses and domestic policies. Given this scenario, it is recommended that multinational companies follow the discussions on tax reform and transfer pricing in an integrated manner.
