Practical guide to a smooth transition to iXBRL
Easy and quick iXBRL filing with Sigma Conso
The European Securities and Markets Authority (ESMA) has made Inline XBRL (iXBRL) format mandatory for consolidated financial statements for groups publishing their accounts under IFRS, from January 1st, 2020 onwards.
In this guide, we will:
- Provide a definition of this publication format
- See how it differs from the XBRL format
- Look at how to implement this new requirement in a simple way.

1. What is iXBRL? How is it different from XBRL?
XBRL (for eXtensible Business Reporting Language) is an open source financial reporting digital format. This format, which has been adopted by more than 100 financial regulators around the world, makes data machine-readable, increases data accuracy, and facilitates comparisons and analysis.
However, the XBRL format has one drawback: it can be interpreted by machines only.
An XBRL document is composed of XML files that require a specific software component (a rendering engine) to present the data in a human-readable format.
*A rendering engine is a software component that translates the markup language in plain text.
About iXBRL (inline XBRL)
The Inline XBRL (iXBRL) format is an “upgrade” of the XBRL specification, to make documents readable for both humans and machines.
iXBRL, also called xHTML, is a format in which XBRL data is embedded in an HTML file. The idea behind the development of iXBRL is to allow companies and people in charge of producing financial statements to keep the layout of the original document, while including:
- XBRL tags, to make the information accessible to machines
- and xHTML tags, to make the information human-readable.
iXBRL was originally developed by XBRL International to meet the requirements of the UK’s HMRC (Her Majesty’s Revenue and Customs).
iXBRL vs. XBRL
|Human & Machine Readability||Machine readable||Human and machine readable|
|File Types/Extensions||Typically has .XML file extension||Typically has .html/.xhtml file extension. XBRL metadata is embedded in the file to facilitate rendering.|
|Encoding Standard||XML||XML and XHTML|
|Output Type||Tabular||WYSIWYG (What you see is what you get)|
|Rendering Options||Special applications (XBRL viewers) required for rendering on display devices||Human Readable layer rendered directly on browsers and printers. XBRL viewer would be needed only to view the XBRL layer.|
|Formatting Options||Limited flexibility||High flexibility to format contents|
|Complexity||Less complex compared to iXBRL||Complex compared to XBRL|
|Filing Process||Multi-step – XBRL (machine-readable) and HTML (human readable) instance documents to be filed separately.||Single step – both human readable as well as machine-readable formats are available in a single instance document|
Implementation of iXBRL around the world, in 7 major steps
- April 2011: companies in the UK started filing their annual accounts and tax returns in iXBRL format with their tax authorities (HMRC).
- Japan’s Financial Services Agency (JFSA) mandated XBRL in 2008, which will be replaced by iXBRL in 2013.
- In 2012, the Revenue Commissioners of Ireland (RCI) offered its taxpayers the option of filing their financial statements in iXBRL format on a voluntary basis. Filing in iXBRL format became mandatory in October 2014.
Other countries will follow suit the following years:
- 2015: Denmark and Australia implemented the iXBRL format.
- 2018: South Africa
- 2019: United States and Malaysia
- Finally, ESMA in Europe makes the iXBRL format mandatory for the filing of consolidated financial statements for groups publishing their accounts under IFRS, for any financial year beginning on or after 1 January 2020.
2. Implementation in Europe: the milestones
In 2017, ESMA (the European Securities and Market Authority) decided to adopt the European Single Electronic Format (ESEF) for the submission of IFRS consolidated statements for accounting periods starting 1st of January 2020 or later.
The purpose of this single European electronic format (ESEF) is to facilitate the accessibility, analysis and comparability of annual financial reports.
The ESEF specify that
- The XBRL ‘tags’ shall be embedded in the XHTML document using the Inline XBRL technology which allows to encapsulate the XBRL tags in the XHTML document within a single document set;
- A set of XBRL tag to be used by is provided by ESMA in a form of an XBRL taxonomy
For the first two years, only the primary financial statements shall be mandatorily marked up; afterwards the entire set of IFRS consolidated financial statements shall be marked with XBRL tags.
3. The 3 benefits of iXBRL
Benefit # 1: A single document to be filed
The digital reporting in iXBRL will allow groups to move away from a dual reporting in HTML and XBRL format to a single reporting in structured format (iXBRL).
With this single format, you no longer have to worry about inconsistencies or differences in the documents you file with the financial authorities.
Benefit # 2: Smoother filing process
With only one document to file, preparation is simpler and quicker, given the iterative nature of the financial statement preparation process, which involves frequent revisions and updates. With the switch to iXBRL, you make all these changes in a single document (iXBRL) instead of two documents in parallel (HTML and XBRL).
Benefit #3: Easier to review
With iXBRL, review is simple and intuitive, since the tagging is in documents familiar to Finance departments. CFOs can easily read and view the tags in the document itself. This process is simpler than reviewing a document in XBRL format, which requires either Excel output or the use of an XBRL reader to review the tags, which are not very explicit out of context.
4. SaaS, a smart way to implement iXBRL
What are the benefits of using SaaS for digital reporting in iXBRL?
This is what SaaS offers:
An efficient process
The overall preparation of the financial statements involves the collaboration of several stakeholders and requires frequent changes and updates, while publication deadlines are tight.
SaaS solutions offer a centralized platform where everyone works transparently and in real time in a collaborative mode. All users, including your external service providers, always have access to the latest version of the document.
By using a SaaS platform, you save time, get streamlined processes and happier teams.
Linked spreadsheets, easy updates and embedded XBRL tags
Most SaaS solutions also allow you to update your figures much more easily, as you work on the project.
You change a figure in one place, and the change is reflected wherever needed in the document. Your figures remain linked at all times, throughout the document, regardless of the output format.
One single filing, a unique source of truth for your stakeholders
Most SaaS platforms allow you to generate multiple output formats from the document you are working on. This means that any changes you make to your source document are instantly reflected in all output formats (XBRL/ iXBRL, HTML, Word, PDF). This allows you to make your filings with the administration, send a communication to shareholders, make your annual report available for download on your site in PDF format (or even better, offer an interactive document in iXBRL), all in near real time.
