Tax Reform and Supply Chains: Why Supplier Selection Will Become a Strategic Decision

The new framework established by Constitutional Amendment No. 132/2023 and regulated by Supplementary Law No. 214/2025 is based on the principles of tax neutrality and broad non-cumulativity, aiming to reduce tax distortions in business decision-making. In practice, however, this new framework will require companies to incorporate increasingly sophisticated tax variables into their supplier selection and management processes.

Historically, supplier selection has been driven by factors such as price, quality, delivery time, operational capacity, and service levels. While these considerations remain essential, the post-reform environment will require a broader perspective. The manner in which each supplier is positioned within the new IBS and CBS tax system may directly affect the economic efficiency of the production chain and the acquiring company’s ability to benefit from tax credits. Procurement management will cease to be an exclusively commercial function and will also become a significant tax and financial concern.

In this context, understanding the tax structure of business partners will become an integral component of corporate governance processes. Companies that fail to properly understand the tax dynamics of their supply chains may face decreased competitiveness, reduced margins, and difficulties in capturing the benefits expected from the new tax framework. Supplier selection will no longer have merely operational consequences; it will directly influence an organization’s tax efficiency.

Another important aspect is that Tax Reform is likely to increase the need for ongoing supplier monitoring and qualification. The ability to generate and preserve IBS and CBS tax credits will increasingly depend on the quality of information transmitted throughout the supply chain and on the proper tax compliance of all participants in the system. As a result, companies will need to invest in technology, database reviews, system integration, and stronger tax compliance mechanisms. Supply chain management will therefore begin incorporating controls that were traditionally limited to tax and accounting departments.

The reforms may also influence broader business strategies. Decisions involving outsourcing, production verticalization, centralized procurement, contract negotiations, and group restructuring will require a deeper assessment of their tax implications. In many sectors, long-standing commercial relationships may need to be reassessed to determine whether they remain efficient under the new rules. What currently represents the best operational alternative may not necessarily remain the most efficient solution within a value-added taxation environment characterized by extensive credit recovery mechanisms.

Tax Reform also presents a new challenge for corporate leadership: fostering greater integration among procurement, supply chain, legal, tax, controllership, and finance departments. Decision-making can no longer occur in isolated silos. Corporate competitiveness will increasingly depend on the ability to analyze the supply chain holistically, combining operational, financial, tax, and strategic considerations within a single decision-making process.

More than a legislative change, Tax Reform introduces a new way of thinking about business relationships. Rather than viewing suppliers merely as providers of goods and services, companies will increasingly assess them as essential components of their tax strategy and overall economic efficiency.

In this new environment, organizations that proactively review their supply chains, strengthen governance processes, and incorporate tax considerations into procurement decisions will be better positioned to preserve margins, reduce risks, and build sustainable competitive advantages throughout the transition period and after the full implementation of the new tax system.
