What You Need to Know About iXBRL Tagging
Her Majesty’s Revenue and Customs (HMRC) is just one body that requires companies to file their corporation tax returns and accounts in iXBRL format.
This requirement has been in place for several years – specifically, since 1 January 2010, when the legislation came into force that required most companies’ corporation tax returns and accounts to be iXBRL tagged in respect of any returns filed on or after 1 April 2011.
As a result of this legislation, you must understand your responsibilities regarding iXBRL tagging if you are required to submit a company tax return to HMRC.
What is iXBRL tagging?
Let’s deep dive into “what is iXBRL Tagging.” The vast majority of companies that file a corporation tax return with HMRC will have to ensure that their company tax return (also known as a CT600), along with their accompanying accounts, are tagged in iXBRL format before filing with HMRC.
There are a limited number of cases where iXBRL tagging isn’t required. In such instances, other file formats, such as pdf, should be accepted by HMRC. Given the relatively small number of companies that fall into the exemption, it’s highly likely that your company’s return and accounts will have to be iXBRL tagged.
Luckily, if you have to comply with HMRC’s tagging requirements, it’s worth noting that the process of tagging your company’s accounts shouldn’t interfere with the presentation of the accounts. This means you can continue using the same layout and style as you have always done.
In essence, a taxonomy operates in a similar way to a dictionary. According to XBRL International, taxonomies “define the specific tags that are used for individual items of data (such as “net profit”), their attributes, and their interrelationships.”
HMRC accepts several taxonomies for filing, a list of which is available to view here.
