The Special Investigation Unit (SIU) was established in 2017, following the restructure of the Internal Affairs Division. Located on the third floor of the Guyana Post Office Corporation Building (GPO), the unit has been divided into two arms to effectively ensure that compliance and integrity are maintained within the Guyana Revenue Authority. In 2018, SIU surpassed its projected goal as a result of assistance (reports) received by staff and external stakeholders, with 90% of reports being addressed within three (3) months.
