The Chartered Institute of Taxation (CIOT)

The Chartered Institute of Taxation (CIOT)is a registered charity (number 1037771) and the leading professional body in the United Kingdom concerned solely with taxation. The CIOT deals with all aspects of direct and indirect taxation.

The primary purpose of the CIOT is to promote education in and the study of the administration and practice of taxation. One of its key aims is to achieve a better, more efficient, tax system for all affected by it – taxpayers, advisers and the authorities. The CIOT's comments and recommendations on tax issues are made solely in order to achieve its aims: it is entirely apolitical in its work.

The CIOT administers and awards two qualifications: the CTA (Chartered Tax Adviser) qualification for domestic tax practitioners in the United Kingdom, and ADIT (the Advanced Diploma in International Taxation) for international tax professionals around the world.
