The value-added tax (VAT) is meant to be an efficient and self-enforcing tax on consumption. Yet, being a rather sophisticated tax, the VAT can also be complex and costly to administer. By examining the case of Rwanda, this paper assesses the extent to which the VAT’s potential materialises in the context of a lower-income countries. Using a mixed-methods approach, which combines qualitative information from focus group discussions with the analysis of administrative and survey data, this paper makes two contributions. First, it documents reporting inconsistencies in VAT data, providing new evidence on how weak capacity prevents tax administrations in lower-income countries from reaping the full benefits of the VAT. Second, it shows that the VAT, as applied in practice, differs substantially from its theoretical functioning. This generates differences in tax burdens across firms, despite a proportional tax rate, with important distributional implications. We also document that the VAT chain often breaks down, with implications on the VAT’s efficiency.

The Policy Research Working Paper Series disseminates the findings of work in progress to encourage the exchange of ideas about development issues. An objective of the series is to get the findings out quickly, even if the presentations are less than fully polished. The papers carry the names of the authors and should be cited accordingly. The findings, interpretations, and conclusions expressed in this paper are entirely those of the authors. They do not necessarily represent the views of the International Bank for Reconstruction and Development/World Bank and its affiliated organizations, or those of the Executive Directors of the World Bank or the governments they represent. Policy Research Working Paper 9993Did increases in mask supply slow the spread of COVID-19? Rwanda licensed and incentivized textile manufacturers to produce high-quality masks at the start of the COVID-19 pandemic. This paper exploits spatial variation in exposure to mask manufacturing through textile trade networks within an event-study design using receipt-level tax data. Licensing domestic mask manufacturers conservatively reduced mask prices by 8.8% and reduced monthly growth in COVID-19 infections (proxied by demand for anti-fever medicine) by 12%. The dynamics of the results suggest that increased mask quality explains reduced infections, in a context where there was strict enforcement of mask mandates and informal markets for masks.

It is part of a larger effort by the World Bank to provide open access to its research and make a contribution to development policy discussions around the world.
