Job Title: Expressions of Interest: Individual Consultant to Conduct a Study on “The Potential and Opportunities for Taxing the Informal Sector in Tanzania”.

Location: Dar es Salaam, Tanzania (Remote working is acceptable)
Brief Description of the assignment: Assessment of the potential and options for increasing tax revenues through informal sector taxation in Tanzania
Department making the request: Tanzania Country Office
Period of assignment: 3 months (May 15, 2023 – August 15, 2023)
Expected start date of the assignment: May 15, 2023


  • Tanzania’s tax to GDP ratio stands at about 11.1% (2020/2021), out of which income taxes are 3.9% of GDP, value added tax are 3.2%, excise at 1.8%, other taxes are 1.5%, and import duties are 0.8%. Tanzania’s 11.1% tax to GDP ratio is lower than the sub-Saharan Africa average of 16.3% of GDP, 19.8% of GDP for SADC, and 14.6% of GDP for EAC.
  • While Tanzania’s tax to GDP ratio is low, the country’s financing needs remain enormous but with limited financing options.
  • Tanzania’s financing gap is projected at 1.2% of GDP in 2021/2022, but the option of debt financing is increasingly limited as total debt and debt service obligations rise. Total public debt increased from 38.0% of GDP in 2020 to 42.2% of GDP in 2022. Total public debt service on the other hand increased to 6.3% of GDP in 2022 from 5.0% of GDP in 2021.
  • Tax administration efficiency is touted as one of the main options to increase Tanzania’s tax to GDP ratio. Tax administration measures particularly aimed at bringing the informal sector into the tax bracket could have potentially impactful benefits. The study therefore assesses the potential for informal sector taxation to increase tax revenues.

The Call

  • The purpose of this consultancy is to support in undertaking the study on “The Potential and Opportunities for Taxing the Informal Sector in Tanzania”.

Duties and Responsibilities of the Consultant
Under the overall guidance of the Country Manager, Tanzania Country Office (COTZ) and the immediate supervision of the Task Manager for this assignment, the consultant’s tasks are to, inter alia:

  • Review literature and document some of the best-case studies in informal sector taxation in Africa and globally
  • Recommend actionable policy options to bring the informal sector into the tax net (increase tax compliance). Specifically, the options will include the exploration of the potential, opportunities and challenges of adopting the following approaches:
    • Associational taxation (identifiable grouping taxation)
    • Presumptive taxes
    • Tax administration segmentation
    • Tax-for-service approach
    • Decentralize/delegate informal tax collection to local authorities
    • Auctioning tax collection rights to private entities
  • Disseminate the results at the internal Bank seminar and to stakeholders in Tanzania
