## Summary

The Foreign Commonwealth and Development Office (FCDO) in the United Kingdom is extending a contract with Cowater International for the Tax Systems Transformation Programme (TSTP) in Ethiopia. This programme focuses on enhancing Ethiopia's tax infrastructure to improve revenue generation in a responsible and equitable manner. The extension, based on regulation 72(1)(b) of the Public Contracts Regulations 2015, will run from 13 March 2026 to 13 March 2028. The original tender was awarded in 2019 through a restricted procedure and will continue with a budget that does not exceed the initial £27,167,193 allocation. This extension aims to support the Ethiopian government's macroeconomic reform efforts and involves foreign economic-aid-related services in the region of Ethiopia. The procurement method used is a limited procedure without prior publication, aligning with GPA standards, and remains within the original value of the existing agreement.

Businesses with expertise in foreign economic-aid-related services or those offering consultancy in tax system reforms will find this tender an opportunity to contribute to significant international development efforts. Given Cowater International's role as the primary contractor, firms looking to subcontract or offer specialist consultancy can explore collaboration, especially specialists with knowledge in administrative capabilities, IT reforms, and policy reformation. This project provides a path for business growth by enabling firms to build a distinguished portfolio in international public service consulting and program delivery in partnership with a major development authority like the FCDO. The programme offers opportunities for embedding technical assistance and knowledge transfer, crucial for firms looking to expand their footprint in the international development sector.

### Lot Information

Lot 1

This notice is to indicate that the Foreign, Commonwealth & Development Office (FCDO) proposes to extend the contract with the named supplier for the Tax System Transformation programme (TSTP) operating in Ethiopia in a manner that is necessary to support Ethiopia's tax reform programme. The contractual extension would run for 24 months from its current proposed end date of 13 March 2026 up to 13 March 2028. The anticipated expenditure in the period between 13 March 2026 and 13 March 2028 will be up to PS4,843,000 (which therefore falls within the contract's financial headroom, with FCDO having spent only PS18,005,643 of the PS27,167,193 value of this contract to date). This notice constitutes a Voluntary ex ante notice under regulation 99 of the Public Contracts Regulations 2015. The Authority considers that the award of this contract modification is permitted under regulation 72(1)(b) of those Regulations, and therefore subject to publication of a notice under that provision, however the Authority also intends to observe a 10 day standstill period under regulation 99(3)(c). Further details are provided later in this notice. 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. A TSTP extension would enable 24 months of continuous outputs/deliverables to existing activities supporting Government of Ethiopia ministries such as the Ministry of Finance and Ministry of Revenue. To continue to assist the Ethiopian Government raise tax revenues in a responsible and equitable way with areas of activity during the extension period will potentially include; Continue embedded technical assistance and specialist consultancy across core MOR Directorates; Implementation of the revenue administration reform roadmap, with monitoring routines institutionalised; Strengthened donor coordination and delivery alignment; Knowledge transfer with phased drawdown of embedded advisers; Transfer of donor coordination responsibilities to create ownership, tools, and coordination structures; Continue systematic monitoring, evaluation and learning to sustain performance and course correction; Plan and deliver a sustained exit strategy aligned with the requirement of NMTRS. Additional information: The extension does not increase the value of the contract.

Options: 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 PS10 million. A contract amendment in February 2024 applied the advertised 2-year extension option and reduced the value of the contract from PS27, 167,193 to PS18,005,643. 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 PS27,167,193

### Procurement Information

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 PS500k 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 is additionally observing a 10 day standstill period 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.
