Lot #1Tax Systems Transformation Programme (TSTP) 7 yrs

The purpose of the Tax Systems Transformation Programme (TSTP)is to assist Government of Ethiopia raising tax revenues in a responsible and equitable manner. The objective of this contract for services is to manage the Accelerated Delivery component of the overall programme on three outcomes: an equitable and business friendly tax environment; improved voluntary compliance; increased GoE

revenues. Accelerated Delivery translates political will at the highest level into coordinated and technically sound reform of Ethiopian tax systems. The TSTP contract brings together ‘delivery’ and technical tax expertise from specialist consultancy, UK HMRC, and other development partners to

support Ethiopia in meeting the financing needs of its 10-year prosperity plan, macroeconomic reforms, and supporting an eventual exit from aid. It provides a blend of long-term embedded advisers and short-term experts to deliver improved business processes, enhanced administrative capabilities, improved IT, reformed tax policy, and lower compliance costs for taxpayers.

Publisher note: Extension of the contract beyond the advertised scope without prior publication of a call for competition The Foreign, Commonwealth & Development Office (FCDO) intends to award a 24 month extension to the TSTP contract with Cowater International. This amendment is made under Regulation 72(1)(b) of the Public Contracts Regulations 2015, which permits modifications because additional services by the original contractor have become necessary where a change of contractor cannot be made for economic or technical reasons and such change would cause significant inconvenience of substantial duplication of costs for the contracting authority. The modification does not exceed 50% of the original contract value. The original contract allowed for a 24 month extension to 13 March 2026 which is currently being used. The extension to 13 March 2028 is necessary to support the Government of Ethiopia to complete its vital macro-economic reform programme and additional services are necessary to ensure continuity of support to deliver its reforms. Delivery of the original contract has been delayed at various points by a number of events beyond control of the Authority, Conflict Covid, & recent disruption to wider reforms. This extension will allow continuity of support to deliver the reforms. The success of this project is a key element of the British Government’s foreign policy in this region. A change of contractor cannot be made for economic and technical reasons related to interoperability with the existing services. The current contractor (Cowater) holds contracts with a number of personnel (embedded advisers) who are indispensable to the success of the programme. There is no guarantee that the embedded advisers would be prepared or obliged to transfer to a new provider, if that were possible, and given their indispensability to the success of the programme that is not a tolerable risk for the Authority. These advisers have in-depth experience and knowledge of the revenue programme to date, and relationships and skills which are indispensable in terms of working on implementation with the national Government and the international financial institutions whose support is key to the programme. The programme has to be delivered at speed, and there is an onerous 3 monthly reporting requirement to the international institutions involved without which the wider funding flow is at risk. It would therefore be wholly unrealistic to attempt to insert new individuals into such roles in the remaining 2 years of the project, given the time required for them to get up to speed on the projects against this background, and inherent risks. This would undermine effective delivery, which is fundamentally important in the particular political context in Ethiopia. A change in contractor would cause significant inconvenience or substantial duplication of costs. Any new personnel would need a substantial handover involving significant knowledge transfer, in particular in a context of running another 2 years (as extended) and given the ongoing 3 monthly reporting regime on top of the need to progress the project itself with speed. That would require the Authority to pay for the existing supplier to handover in parallel with the new contract for some time, which would increase, and duplicate costs, of up to £500k over a significant handover period. The extension does not increase the original contract value by more than 50%. For the reasons above the Authority considers that regulation 72(1)(b) of PCR 2015 applies to this contract modification. Whilst that provision does in fact require publication of a transparency notice, the Authority has additionally observed a 10 day standstill period (ended on 13 October 2025)aligned to regulation 99 (3) before concluding the modification with Cowater, and in the event of a claim under the Public Contracts Regulations 2015 will rely on these circumstances in relation to the first ground of regulation 99, should it be applicable

    • Change The original contract included an option to extend the contract by 2 years to 13 March 2026 and an increase in contract value by an additional £10 million. A contract amendment in February 2024 applied the advertised 2-year extension option and reduced the value of the contract from £27, 167,193 to £18,005,643. The reduction in budget was as a result of FCDO Business Panning adjustments. The scope and objectives remained the same but in line with the flexible and adaptive approach some activities were scaled back. This modification will extend the contract for a further two years from 13 March 2026 to 13 March 2028 but remain within the original contract value of £27,167,193, Need for additional works, services or supplies by the original contractor/concessionaire: This amendment is made under Regulation 72(1)(b) of the Public Contracts Regulations 2015, which permits modifications because additional services by the original contractor have become necessary where a change of contractor cannot be made for economic or technical reasons and such change would cause significant inconvenience of substantial duplication of costs for the contracting authority.
