TITLE: United States Securities and Exchange Commission Updates 2026 XBRL Taxonomies
BODY:
On March 16, 2026, the Securities and Exchange Commission (SEC) upgraded its Electronic Data Gathering, Analysis, and Retrieval (EDGAR) system to Release 26.1 to support the 2026 eXtensible Business Reporting Language (XBRL) taxonomies. The 2026 taxonomies are compatible only with other 2026 taxonomy versions and incorporate amendments from draft versions posted for technical feedback between September 12 and November 12, 2025.
Key updates across the 2026 taxonomies include: the Document and Entity Information taxonomy now accepts NYSETX as a value representing NYSE Texas; the Filing Fee Disclosure taxonomy relocates four concepts to a new fees summary role; the Open-End Fund taxonomy requires changes to custom definition arcs targeting extensible enumeration lists; the Resource Extraction Payments taxonomy removes an unused data type declaration; the Self-Regulatory Organizations taxonomy assigns labels to certain elements from the document and entity information namespace; and the Special Purpose Acquisition Company taxonomy adds a new definition and presentation link role for compensation nature axis. The 2026 U.S. GAAP Financial Reporting taxonomy and SEC Reporting Taxonomy reflect versions released by the Financial Accounting Standards Board on December 15, 2025. Additional 2026 taxonomies include those for closed-end funds, countries, currencies, cybersecurity disclosure, executive compensation disclosure, exchanges, funds, industry classifications, security-based swaps, and variable insurance products.
The SEC will not remove 2024 taxonomy versions before June 2026. Although EDGAR accepts both 2026 and 2025 taxonomy versions, the SEC encourages companies to transition to 2026 taxonomies for reporting periods ending on or after March 16, 2026, to benefit from updated tags and improvements.
