The Guyana Revenue Authority (GRA) was established on January 27, 2000, following the merger of the Inland Revenue and Customs & Excise Departments. These changes were as a result of the passing of the legislation in the Tax Act. The transition has allowed the Revenue Body to continue to evolve its operations and administration, increasing its infrastructure and technical capacity over the years. In its continued pursuit to improve our service delivery and tax administration to the Republic of Guyana, and across the global spectrum, Value Added Tax (VAT) and the Taxpayer Identification Number (TIN), were both introduced, paving the way for greater tax control and data monitoring. 

Since the introduction of these two major initiatives, several data management software programmes, including TRIPS followed by the recently introduced ASYCUDA, including several major tax programmes were introduced to further catapult our tax administration organization and initiatives, thereby further improving our revenue targets. Our website provides a plethora of information on these initiatives and tax matters that will aid you in successfully transacting business with the Guyana Revenue Authority (GRA). https://www.gra.gov.gy
