Coordinating Tax Reforms in the Poorest Countries - Can Lost Tariffs be Recouped?

This World Bank working paper examines the feasibility of switching from trade taxes to domestic consumption taxes in low-income countries, focusing on Nepal as a case study. The primary concern is whether such a revenue-neutral reform can offset potential losses in tax revenue resulting from reduced tariffs, particularly under regional free trade agreements (RFTAs).

Key Findings:

Mixed Record of Revenue Recovery: Analysis of low-income countries over 25 years shows a mixed record of successfully offsetting reductions in trade tax revenue through such reforms.
Sensitivity to Domestic Tax Enforcement: The effectiveness of a revenue-neutral transition depends heavily on the strictness of enforcement for domestic consumption taxes (like VAT).
Minimizing Revenue Loss Through Sensitive Lists: Intra-regional free trade agreements can lead to significant revenue losses, but these can be mitigated through the judicious use of "Sensitive Lists" that still cover most traded goods as required by GATT Article XXIV.

Case Study: Nepal

The paper uses unique customs data from Nepal to model two scenarios:

1. Proportional Tariff Cuts with Strict VAT Implementation: This scenario explores the impact of coordinated tariff reductions and robust VAT enforcement on revenue and domestic production.
2. Regional Free Trade Agreement (RFTA): This scenario examines potential tax losses resulting from reduced tariffs under an RFTA and the effectiveness of sensitive lists in mitigating these losses.

Key Results:

Nepal's experience suggests that successful coordination between tariff cuts and VAT implementation is crucial for revenue neutrality.
* Even with robust VAT enforcement, significant revenue losses could occur due to RFTAs unless sensitive lists are employed effectively.

Implications:

The study highlights the importance of strong domestic tax administration in ensuring successful revenue-neutral tax reforms. It also emphasizes the need for carefully tailored "sensitive lists" within regional trade agreements to protect revenue bases, especially in low-income countries with large informal sectors.
