Summary of the VAT Gap Analysis in Estonia

Core Content

This Technical Assistance Report by the International Monetary Fund (IMF) provides an analysis of the Value-Added Tax (VAT) compliance gap in Estonia from 2007 to 2012 using the RA-GAP (Revenue Administration GAP Analysis Program) methodology. The report highlights the performance of Estonia's VAT system, the factors contributing to the compliance gap, and the potential for improvement in tax gap analysis and management.

Main Components of the Report

1. VAT Revenue Performance

• VAT as a % of GDP: Estonia's VAT revenues have been between 8% and 9% of GDP since 2000.
• Trend Analysis: Until 2007, nominal VAT revenues increased, but during the 2008–2009 recession, they decreased.
• Rate Changes: In 2009, the reduced VAT rate for medicines and other products increased from 5% to 9%, and the standard rate increased from 18% to 20%.
• Post-2009 Growth: After 2009, VAT revenues increased, but not as fast as GDP and final consumption growth, indicating a widening compliance gap.

2. VAT Compliance Gap Estimation

• Definition: The VAT compliance gap is the difference between potential VAT revenues and actual collections.
• RA-GAP Methodology: A top-down approach is used, estimating potential VAT using national accounts data and actual collections using tax returns data.
• Period Covered: 2007–2012.
• Compliance Gap Growth: The compliance gap increased significantly between 2008–2011, almost doubling in size, with losses rising by over €150 million.

3. Decomposition of the Compliance Gap

• Assessment Gap: The difference between declared VAT and potential VAT.
• Collections Gap: The difference between declared VAT and actual collections.
• Trends: The assessment gap increased from 2009–2011, while the collections gap peaked in 2009 and then declined, likely due to the introduction of automated debt management in 2010.

4. Sectoral Analysis of the Compliance Gap

• Sectoral Distribution: Over 60% of VAT is collected in the wholesale and retail sector, reflecting the high proportion of imported goods in final consumption.
• High Compliance Gaps: Sectors with significant compliance gaps include Agriculture, Construction, Wholesale and Retail, and Professional Services.
• 2012 Comparison: The size of compliance gaps in 2012 was similar to 2009, but the Manufacturing Sector showed a notable difference.

5. C-Efficiency and VAT Gap Analysis

• C-Efficiency Definition: A measure of VAT generation relative to economic aggregates, taking into account both compliance and policy gaps.
• Trend in C-Efficiency: C-efficiency in Estonia increased from 2005–2007, then decreased after 2008 and remained stable.
• Policy Gap: The policy gap remained relatively constant, while the compliance gap increased, suggesting a growing problem in tax compliance.

6. Comparison with Other Estimates

• Consistency: RA-GAP estimates are generally consistent with those of the Estonian Tax and Customs Board (ETCB) and the Center for Social and Economic Research (CASE).
• Volatility Differences: RA-GAP estimates are smoother than ETCB and CASE estimates due to the use of accrued collections rather than cash-based data.
• Bias Considerations: ETCB's simplified VAT gap model may lead to biases due to the use of the Weighted Average Rate (WAR) and inconsistencies in the tax base and applied rates.

Key Findings

• The VAT compliance gap in Estonia is the largest among all taxes, primarily driven by Missing Trader Intra-Community (MTIC) fraud, which is a form of VAT evasion common in the EU.
• The collections gap decreased after 2010 due to automated debt management systems.
• Sectoral concentration is high, with the wholesale and retail, and construction sectors being the main contributors to the VAT base and compliance gaps.
• The assessment gap increased from 2009–2011, suggesting that more VAT was not being declared or assessed properly.
• The c-efficiency measure shows that the compliance gap has grown relative to policy gaps, indicating a need for improved tax administration.

Recommendations for Further Work

• Improve VAT Gap Estimation: Use RA-GAP's preferred VAT gap model to enhance the reliability of estimates and their year-on-year changes.
• Micro-level Analysis: Conduct a detailed analysis of VAT declarations and adjustments to monitor taxpayer behavior and potential manipulation.
• Longitudinal Risk Profiling: Increase the use of longitudinal data to better assess risks in the context of automated tax administration.
• Annual Publication: Publish non-operationally sensitive tax gap estimates annually to support public debate and policy discussion.
• Qualitative Research: Consider qualitative methods, such as structured interviews with tax experts, to estimate the scale of the dividend tax gap when quantitative data is insufficient.

Conclusion

The report emphasizes that Estonia's VAT compliance gap has been growing, especially from 2008–2011, and that the ETCB's current approach, while useful for strategic risk assessment, could benefit from more accurate and reliable methodologies. The RA-GAP model provides a more consistent and comprehensive way to estimate the compliance gap and should be considered for adoption. The report also highlights the importance of sectoral analysis and the need for continuous improvement in tax administration practices.
