HMRC’s experience with iXBRL data
After four years of successful implementation of iXBRL, HMRC has shared its experience on high quality analysis. The iXBRL has been proven advantageous to HMRC and has provided an improved reporting and analysis capability for tax authorities. It has also helped HMRC to reduce the related costs of recording the data. The primary use of XBRL is to define and exchange financial information, such as financial statements, in a computer readable format. The data available in XBRL can be compared amidst those of thousands of taxpayers who are submitting their accounts in this computer readable format.
HMRC is also planning for significant changes to the iXBRL submission in order to ensure the quality of XBRL fillings is sustained and the basic purpose of XBRL implementation is met. The biggest change is the HMRC’s requirement for detailed level tagging of Profit and Loss Statement where all the expense items need to be tagged with the standard taxonomy element. This requirement will be implemented in the UK GAAP, the IFRS Statutory Accounts and the Corporation Tax XBRL taxonomies. HMRC has also stated that they will be making structural changes to the Corporation Tax XBRL taxonomy.
Some facts related to the HMRC iXBRL submissions received so far:
There are some difficulties highlighted by HMRC which are causing some challenges in using the available iXBRL data. They have pointed out some of the common errors that are found in the iXBRL filings. These include:
- Tagging monetary items as text strings;
- Applying incorrect scale to monetary tags (£10m tagged as just £10);
- Using the incorrect date for a tag;
- Applying an incorrect currency to a value;
- Incorrect use of the negation principle (polarity issues);
- Failing to tag one or more of the Business Mandatory Tags;
- Incorrect tagging and variation in element selection by the filers
HMRC is paying more detailed attention to the returns which appear to lack the expected amount of tagging, filed by the filers. HMRC is also working in close consultation with the software partners to improve their products and services. In order to ensure the complete tagging of data with precise standard elements HMRC has proposed:
- Introduction of new detailed profit and loss account extension taxonomy
- Improvements to the structure of the HMRC computation taxonomy
- New accounts taxonomies (FRS taxonomies)
