On January 26, 2026, the Brazilian Association of Technical Standards (ABNT) published ABNT NBR 17301 – Tax Compliance Management Systems: Requirements with Guidance for Use, establishing a national technical framework for organizations seeking to structure tax compliance practices based on reliability, transparency, and accountability. The standard represents a significant milestone in Brazil by aligning corporate governance and tax compliance with international standards and providing objective guidelines for the systematic fulfillment of tax obligations.
Background and Development
The standard was developed at the request of the Brazilian Federal Revenue Service (RFB) within the context of the Confia Program and resulted from a collaborative effort led by ABNT Commission CEE-309 (Governance of Organizations), the Brazilian counterpart to the international ISO/TC 309 – Governance of Organizations committee.
The project began in November 2024 and was developed throughout 2025 during 25 technical meetings involving representatives from ABNT, the Federal Revenue Service, private companies, and institutional and industry associations, including Abrasca, Febraban, and Getap, as well as invited specialists.
The initiative is based on a key distinction: governance relates to direction, oversight, and accountability, while management concerns day-to-day operations and controls. This distinction is particularly relevant because effective tax compliance systems require both clearly defined responsibilities and governance structures, as well as robust operational processes and controls.
Regulatory Foundations and International Alignment
ABNT NBR 17301 was structured based on three principal references:
Structure and Guidelines
In practical terms, ABNT NBR 17301 describes how an organization should establish, develop, implement, evaluate, maintain, and continuously improve an effective tax compliance management system.
The standard focuses on the development of policies, processes, and internal controls designed to ensure accuracy, completeness, and accountability in tax compliance. It connects three core elements:
(i) Tax obligations (what must be complied with);
(ii) The standard’s requirements and guidelines (how the system should be structured); and
(iii) Internal policies and procedures (how compliance should be implemented and operated within the organization).
The framework follows the PDCA (Plan-Do-Check-Act) methodology and includes the following stages:
Plan: Establish policies, roles, responsibilities, and compliance criteria aligned with the organization’s governance structure;
Do: Implement the defined processes and controls to support compliance with tax obligations;
Check: Monitor and evaluate the performance of the management system, identifying risks and opportunities for improvement; and
Act: Address nonconformities and promote continuous improvement initiatives to strengthen the system.
Integration with ISO Standards, Auditing, and Future Certification
The standard is aligned with Annex SL, the common framework adopted by ISO management system standards. This facilitates integration with existing management systems, including quality and compliance frameworks such as ISO 9001, ISO 37001, and ISO 37301, helping organizations reduce duplication of efforts, costs, and operational complexity.
Because it establishes verifiable requirements, the standard is auditable and supports first-party (internal), second-party (customer or stakeholder), and third-party (independent certification body) audits.
There is also an expectation that the ecosystem surrounding the standard will continue to evolve through the training of implementation professionals and the accreditation of certification bodies, paving the way for future certification programs.
Expected Benefits
For businesses, ABNT NBR 17301 is expected to deliver benefits that extend beyond formal compliance, including:
For tax authorities, the standard contributes to greater transparency, legal certainty, consistency of practices, and the creation of a common language for controls and evidence, fostering a more predictable and collaborative business environment.
Recommended Actions
Organizations are encouraged to assess the maturity of their current tax compliance processes and evaluate the extent to which their internal controls align with the requirements of ABNT NBR 17301, particularly with respect to risk management, documentation and evidence, monitoring activities, and continuous improvement mechanisms.
Our firm remains available to provide guidance on ABNT NBR 17301, clarify its requirements, and assist organizations in implementing robust and effective tax compliance practices.
