iXBRL tagging

We use CoreFiling’s Seahorse tagging software, the same system that is used by HMRC for iXBRL, because we believe it is the best available and is fully compliant with the new FRS and IFRS tagging regimes.

Fully managed IXBRL

Our Fully Managed Service requires only some discussion to approve any potentially contentious tagging and your final sign off. You can be assured that we will manage everything else from tagging your accounts to testing the tagging against HMRC gateway criteria and quality reviews.

iXBRL Quality Review 

Our iXBRL quality review will give you with the confidence that your accounts meet HMRC’s requirements. The quality review will be carried out by our expert iXBRL tagging team. This can be a cost effective was to minimise risks.

iXBRL Direct Access

Our Direct Access Service is our ‘Do It Yourself’ service.  We will provide you with training on the Seahorse software, the iXBRL taxonomies and common pitfalls when tagging. This will enable you to complete the iXBRL tagging yourself. Our training and assistance may be particularly valuable in the first year of tagging under the new FRS/IFRS regime.

Whatever level of iXBRL help you need, our experts can guarantee your accounts are tagged correctly first time and every time.
