Nigerian Tax Research Network Library

Nigeria’s tax to GDP ratio is one of the lowest in the world. At under 6%, it is far below the sub-Saharan African average of 20%, and the 15% considered to be necessary to fund adequate public services. Nigeria has long relied on revenues from oil, but there is now widespread recognition of the need to diversify the sources of the government budget, and build a more sustainable revenue base for inclusive growth.

Key to raising increased tax revenue in an equitable manner, and without impeding economic growth, is rigorous research that can inform both tax policy and practice. To this end, the Nigerian Tax Research Network was launched in September 2017.

The NTRN is coordinated by the International Centre for Tax and Development (ICTD) and funded by the Bill and Melinda Gates Foundation. The NTRN is dedicated to enhancing the generation and exchange of tax knowledge in Nigeria. It is concerned with all topics related to taxation, ranging from tax policy to tax administration, and from academic papers to practical case studies. This library is intended to be of use to members of the NTRN, including tax practitioners and researchers from both Nigerian and international organisations.

  • Tax structures and economic growth in Nigeria: disaggregated empirical evidence
