Summary of "Fiscal and distributional implications of VAT reforms in Zimbabwe"

Core Content

This World Bank Working Paper analyzes the fiscal and distributional implications of Value Added Tax (VAT) reforms in Zimbabwe, focusing on the 2024 budget changes. The study combines a VAT tax gap analysis with a partial fiscal incidence framework to assess the impact of the reforms on government revenue and household welfare.

Main Findings

• Fiscal Impact: The 2024 VAT reforms, which reduce the number of zero-rated and exempted goods and services, are expected to increase VAT revenue by 0.88% of GDP.
• Distributional Impact: These reforms are likely to increase poverty headcount by 1.4 percentage points and increase inequality by 0.14 points, aligning with international evidence that VAT reforms can have regressive effects on low-income households.
• Compensation Mechanism: The paper emphasizes that any VAT reform must be accompanied by compensatory mechanisms, particularly targeted or universal cash transfer programs, to offset the negative distributional impact.
• Informal Economy Consideration: Informal vendors, who are not registered for VAT, contribute significantly to the informal economy, and their exclusion from the tax system can lead to cascading VAT on their goods and services.
• Data and Methodology: The analysis uses data from the 2017 Poverty, Income, Consumption, Expenditure Survey (PICES), Supply and Use Tables (SUT), and VAT regulations. It also incorporates an informality database to estimate the share of informal consumption in Zimbabwe.
• Policy Recommendations: The paper suggests that establishing a nationwide social registry and developing an effective targeting mechanism are necessary to implement compensation programs for low-income households affected by the VAT reforms.

Key Points

1. VAT Structure in Zimbabwe

• VAT is an indirect consumption tax applied at various stages of the value chain.
• The tax system includes four categories of VAT rates: standard rate (15%), zero rate (0%), and exemptions.
• In 2024, most basic commodities previously zero-rated were moved to exempt status, and the zero rate was restricted to exports only.
• The VAT threshold was lowered to USD25,000, and a 5% withholding tax was introduced on transactions with non-VAT registered companies (informal sector).

2. Impact of VAT Reforms

• The reforms are intended to increase tax base and revenue by reducing the number of zero-rated and exempted items.
• However, the poor and low-income households may be disproportionately affected, as they are more likely to consume exempt and zero-rated goods.
• The poverty headcount is expected to increase by 1.4 percentage points, and inequality by 0.14 points due to the reforms.

3. VAT Tax Gap Analysis

• The VAT tax gap is decomposed into policy gap and compliance gap.
• The policy gap reflects the difference between the potential revenue under the standard rate and the actual revenue under the current VAT policy.
• The compliance gap is the difference between the potential revenue under the current policy and the actual collections.
• The estimated VAT policy gap for 2024 is significant, indicating potential for increased revenue if the policy is fully implemented.

4. Methodology Overview

• The study uses a fiscal incidence approach to measure the impact of VAT on household welfare.
• It involves:
  • Preparing a household consumption dataset from PICES 2017.
  • Augmenting the dataset with import data and applying VAT rates.
  • Separating market purchases from total consumption.
  • Mapping consumption items to SUT sectors and COICOP categories.
  • Estimating informal consumption using data from nine comparator countries.

5. Informality and Taxation

• Informal vendors are not registered for VAT and therefore cannot reclaim input tax.
• This can lead to cascading VAT, increasing the final price of goods and services.
• The informal share of consumption in Zimbabwe is estimated at 60%, which is used to adjust the VAT gap analysis.

6. Macro-Micro Validation

• The study validates the data by comparing survey-based consumption and VAT revenue with national accounts.
• In 2017, VAT revenue was $1,092 million, while the survey recorded $174.8 million, or 16% of the total VAT.
• Household consumption in the survey was $11,331 million, or 65% of the national accounts estimate.
• The effective VAT rate based on administrative data was 6.2%, while the survey-based rate was 1.5%, highlighting the underreporting of VAT in the informal sector.

Conclusion

The VAT reforms in Zimbabwe aim to enhance domestic revenue mobilization but could exacerbate poverty and inequality if not accompanied by appropriate compensation mechanisms. The study recommends expanding cash transfer programs to offset the negative effects on low-income households, and investing in a nationwide social registry to improve targeting efficiency. Additionally, improving tax administration and addressing informal sector taxation are critical to ensuring the success and equity of the reforms.
