The Chartered Institute of Taxation (CIOT) is an organisation that helps people learn about the laws around paying and collecting taxes. They provide courses, exams and qualifications to help people become qualified tax professionals. This means that people who have been through the CIOT's courses and exams know how to advise people and businesses on the correct way to pay their taxes. The CIOT also works with governments and other organisations to make sure that tax laws are fair and that they are up to date with the needs of the world.
