Regarding the control of Accountant certification the General Secretariat for Information Systems created "Search of Accountant's Personal Information". This service is available to all citizens and no access codes are required in order to use it.
With this service all tax payers can enter the Accountant's TIN and check the personal information thereof as it was received by the GSIS from the Economic Chamber. This service allows citizens to certify that the Accountant with whom they collaborate or will collaborate has all necessary certifications-licenses by the state authorities.
