About us

The CIOT is the leading body in the UK for taxation professionals dealing with all aspects of taxation. Our primary purpose is to promote education in taxation. One of our key aims is to achieve a more efficient and less complex tax system for all. Our comments and recommendations on tax issues are made solely in order to achieve this aim; we are an entirely apolitical organisation.

Membership of the CIOT is by examination; nationally recognised as the gold standard of UK taxation education. We support our 17,000 members and 4,000 students throughout their tax careers, providing assistance through our London-based head office and worldwide network of 40 branches. The CIOT is a registered charity, number 1037771 and a regulatory body for the purposes of Anti-Money Laundering supervision of tax practitioners.

The CIOT is a member of the Confédération Fiscale Européenne (CFE) and is registered under the European Commission's Transparency register, number 91596579174-61.

Equality, Diversity and Inclusion 

We are committed to ensuring that all our members, students and volunteers feel welcomed, valued and supported, regardless of their background or identity.

We have established an Equality & Diversity Working Party to assist us in ensuring we have clear values which can be demonstrated through our behaviours, actions and operations.
