On June 28, 2018, the Commission adopted amendments requiring the use, on a phased in basis, of Inline XBRL for operating company financial statement information and fund risk/return summary information. See Release No. 33-10514 for details.
What is Inline XBRL?
Inline XBRL is a structured data language that allows filers to prepare a single document that is both human-readable and machine-readable, so that filers need only prepare one Inline XBRL document rather than generate an HTML document of their financial statement information or risk/return summary information and then tag a copy of the data to create a separate XBRL exhibit.
For data users, Inline XBRL provides an easier way to view, access, and explore the contextual information of the underlying data. For example, users can click on individual tagged data points in the filing to find more information about the data, such as citations and hyperlinks to the relevant accounting guidance, narrative definitions for the values, and reporting period information associated with each value.
How are Inline XBRL filings viewed?
The short video below describes some of the features and capabilities of the open source Inline XBRL Viewer.

When must filers begin filing using Inline XBRL?
Operating Company Financial Statement Information
There is a three-year phase-in for U.S. GAAP filers to comply the Inline XBRL requirements, beginning with fiscal periods ending on or after:
- June 15, 2019 for large accelerated filers
- June 15, 2020 for accelerated filers
- June 15, 2021 for all other filers
For IFRS filers, compliance is required beginning with fiscal periods ending on or after June 15, 2021.
Domestic form filers, however, will not become subject to the requirement until their first Form 10-Q filed for a fiscal period ending on or after the applicable compliance date, as opposed to the first filing for a fiscal period ending on or after that date.
Fund Risk/Return Summary Information
Funds have a two-year phase-in to comply with the Inline XBRL requirements as follows, beginning with any initial registration statement (or post-effective amendment that is an annual update to an effective registration statement) that becomes effective on or after:
- September 17, 2020 for large fund groups (with net assets of $1 billion or more as of the end of the most recent fiscal year)
- September 17, 2021 for small fund groups (with net assets of less than $1 billion as of the end of the most recent fiscal year)
Can all forms subject to the Inline XBRL requirements be voluntarily filed using Inline XBRL in the EDGAR system now?
The EDGAR system was modified on March 11, 2019 to accept in Inline XBRL all forms subject to the Inline XBRL requirements.
Operating companies that are not currently subject to the Inline XBRL requirements may voluntarily file in Inline XBRL the forms that will be subject to the Inline XBRL requirements.
Where can I find filings submitted using Inline XBRL?
Inline XBRL filings are available in the EDGAR system alongside other company filings.
Is the Inline Viewer software source code available for download?
The Inline Viewer software is freely available to the public in an effort to facilitate the creation of cost effective Inline XBRL viewers and analytical products.
Where can I find the technical requirements related to filing using Inline XBRL?
The EDGAR Filer Manual provides the technical requirements needed for filers to use Inline XBRL.
