23 July 2019
All elements of the Check Employment Status for Tax service (CEST) were thoroughly tested.
In a series of workshops, officials and external experts, including lawyers, tax and IT professionals, developed the set of rules that underpin the tool. The workshop participants agreed the key relevant facts and points of law and then tested the rules that went into the tool to ensure it gave the correct answer. Those rules were then tested against live and settled cases.
