Five lessons from reforming tax administration in East Africa

After years working alongside revenue authorities in Uganda, Tanzania, Madagascar, and Lesotho, we have distilled five lessons that distinguish reform programs that deliver results from those that stall.

Lesson 1: Start with the process, not the technology

The most common and most costly mistake in tax administration modernization is investing in technology before fixing the underlying process. A new VAT system built on top of a broken workflow does not simplify compliance; it automates the complexity. Before any discussion of systems, portals, or digitalization, successful reform programs map what actually happens in practice: how many steps a taxpayer must complete, how many times they interact with officials, how many documents they must provide, and where discretion and bottlenecks accumulate. In our work with Uganda Revenue Authority, this diagnostic phase revealed that the audit function involved 62 separate steps and up to 65 calendar days. The process redesign reduced this to 19 steps and 18 days. In Madagascar, mapping the VAT refund process showed that 27 steps and three taxpayer visits could be eliminated entirely by integrating the refund request into the filing process with risk-based verification. The lesson is consistent: diagnose before you digitize.

Lesson 2: Measure everything at the baseline

You cannot reform what you have not measured. One of the most important contributions any reform program can make is establishing a rigorous, quantified baseline of current performance — steps, time, documents required, taxpayer contacts, and administrative cost — that can then be used to design targeted improvements, track progress, and demonstrate results. In Tanzania, baseline measurement of the registration process revealed that the coexistence of separate TIN and VAT registration systems was creating duplication that added both taxpayer burden and administrative complexity. Evidence gathered at baseline is also a powerful tool for sustaining political momentum: when ministers and donors can see a 45% reduction in processing time, reform ownership deepens.

Lesson 3: Voluntary compliance is a behavioral challenge as much as a procedural one

Much of the tax reform literature focuses on reducing friction, simplifying procedures and reducing compliance costs. This is important, but it is not sufficient. In our work with the Lesotho Revenue Authority, we found that even where taxpayers understood their obligations and had relatively accessible services, compliance was still suppressed by perceived low benefit, misperceived social norms, and a fundamental trust deficit. Individuals in Lesotho spent an average of 22.3 hours on tax payment activities. But when asked why they did not comply more consistently, the most common response was about perceived value, not time or cost. This insight shifted the reform design from purely procedural improvements toward a communications and trust-building agenda.

Lesson 4: Risk-based administration is the key to sustainable efficiency

Many revenue authorities operate on a blanket-check model, every return subject to the same scrutiny. This approach is administratively burdensome, taxpayer-unfriendly, and ineffective at targeting the compliance risks that actually matter. Across our East African engagements, one of the most consistent reform recommendations has been the introduction of risk-based administration: using data and compliance history to differentiate between taxpayers who warrant intensive attention and those who can be served through streamlined, low-touch processes.

Lesson 5: Capacity and change management are as important as technical design

The best process redesign in the world will not deliver results if the people responsible for implementing it do not understand it, do not trust it, or do not have the skills to operate it. In Bangladesh, our work with the NBR's VAT Wing included six structured training sessions on quality assurance, testing protocols, and systems knowledge transfer. Effective tax reform programs treat capacity building and change management not as add-ons but as core deliverables.

Conclusion

Tax administration reform is hard work that unfolds over years, not months. But programs that start with rigorous diagnosis, establish clear baselines, address behavioral as well as procedural barriers, introduce risk-based administration, and invest in institutional capacity are consistently more likely to deliver lasting improvement.
