We provide a wealth of publications by PwC Rwanda providing informed commentary on current developments in the tax arena, both locally and internationally. Through analysis and comment on new law and judicial decisions of interest, they assist business executives to identify developments and trends in tax law and revenue practice that might impact their business. In this issue: On 24 December 2020, the Commissioner General (CG) of the Rwanda Revenue Authority (RRA) announced that effective 1 January 2021, all taxpayers must secure invoices/receipts generated by the Electronic Invoicing System (EIS) as documentary evidence to support tax deductions associated with expenses for the years of income from 2021 onwards. This announcement raised a number of concerns amongst the public. Since then, RRA has engaged the private sector on the modalities of implementing this directive and issued a number of clarifying announcements. The following PwC Rwanda Tax Alert summarises some of the important clarifications made by RRA and challenges that taxpayers are still likely to face.
