2021 XBRL Taxonomies Update

March 23, 2021

On March 22, 2021, the Electronic Data Gathering, Analysis, and Retrieval (EDGAR) system was upgraded to Release 21.1 and now supports the 2021 taxonomies listed below. The 2021 U.S. Generally Accepted Accounting Principles Financial Reporting (U.S. GAAP) Taxonomy and the 2021 SEC Reporting Taxonomy (SRT) reflect the same taxonomies that the Financial Accounting Standards Board (FASB) made available on its website on December 17, 2020.

The other 2021 taxonomies listed below are the final versions of the draft taxonomies posted by Commission staff for public comment on September 1, 2020. Refer to the final 2021 taxonomies’ Release Notes for details of the changes.

  • U.S. GAAP
  • SEC Reporting (SRT)
  • Countries (COUNTRY)
  • Currencies (CURRENCY)
  • Document and Entity (DEI)
  • Exchanges (EXCH)
  • North American Industry Classification System (NAICS)
  • Risk-Return (RR)
  • Standard Industrial Classification (SIC)
  • State and Province (STPR)

The staff does not anticipate the removal of the 2019 U.S. GAAP, 2019 SRT, or any previous year versions of the other taxonomies to occur before June 2021. Please see for a complete listing of supported standard taxonomies.

The staff strongly encourages companies to use the most recent version of taxonomy releases for their XBRL exhibits to take advantage of the most up-to-date tags related to new accounting standards and other improvements. Filers should consider transitioning to the 2021 taxonomies for the earliest reporting period that ends after March 22, 2021, but not for reporting periods that end before March 22, 2021.
