INTRODUCTIONThe Tanzania Revenue Authority (TRA) is Government Agency established by the TRA Act Chapter 399 and became operational on 1^st July, 1996. Over the years of its existence the Authority has been conducting its business guided by five-years Corporate Plans. The plan has aided the Authority to have a common strategic direction in the course of discharging its mandate. This approach of managing corporate affairs has enabled the Authority to achieve remarkable performance in the mobilization of the Government revenue.The Fourth five-years Corporate Plan (CP4) was implemented for a period of four years in order to be in sync with the UN Sustainable Development Goals adopted in September 2015; National Vision 2015; the second National Five Years Development Plan – FYDP II (2016/17-2020/21); and the zeal of 5^th Phase Government which was launched in June 2016 calls for the need to undertake interventions aimed at the enhancing domestic resource mobilization. The emphasis on revenue from these documents had made it necessary to take them onboard in formulating a new TRA’s strategic plan.Additionally, the IMF’s TADAT Assessment conducted in February 2016 brought up a number of pertinent issues that needed to be addressed by the TRA at the strategic level. Consequently, all these factors necessitated early development of Fifth Corporate Plan (CP5) for another period of five years commencing July 2017
