Summary of the Philippines: Selected Issues

Core Content

This document is an IMF staff report analyzing tax collections and foreign workers and remittances in the Philippines. It provides empirical evidence on the evolution of tax revenue, the factors influencing its growth, and the implications of the country's tax system and remittances on the macroeconomy.

Main Findings on Tax Collections

1. Fiscal Challenges and Reforms

• The Philippines faces significant fiscal challenges due to a low revenue-to-GDP ratio.
• The government has implemented a fiscal strategy focused on revenue mobilization.
• Key reforms include:
  • Alcohol and tobacco excise reforms (approved in 2012, effective in 2013), which are expected to increase tax collections by 0.3% of GDP.
  • Internal tax administration reforms, which have made progress.
• The goal is to increase the revenue-to-GDP ratio from 14.3% in 2012 to 18% by 2016, and the tax ratio from 12.8% to 16%.

2. Historical Tax Collection Trends

• Tax-to-GDP ratio increased from 12.1% in 2009 to 12.8% in 2012.
• This increase was driven by higher collections of CIT, PIT, and VAT, which offset declines in excises and import duties.
• The ratio still lags behind the pre-global recession level of 13.5% of GDP.

3. Composition of Tax Revenue

• CIT and VAT are the two largest components of tax revenue, each accounting for about 30%.
• PIT accounts for 16%, excises for 7%, and import duties for 4%.
• The "other taxes" category includes various levies such as taxes on interest income.

4. Impact of Economic Conditions

• Tax collections are closely tied to economic growth and tax administration improvements.
• During 2011–12, 80% of tax collection increases were attributed to the tax base (economic growth), while the residual component (unrelated to base) was estimated at 0.3% of GDP annually.
• The residual may reflect improvements in tax administration, as there were no major policy changes during this period.

5. Decomposition of Tax Collection Increases

• Tax collection growth is decomposed into:
  • Tax base component: related to economic conditions.
  • Residual component: attributed to policy and administrative changes.
• For CIT, the residual component was negative in 2012, possibly due to tax incentives.
• For PIT and VAT, the residual component was positive, likely due to tax administration efforts.

6. Sensitivity of Residual Estimates

• The residual component is highly sensitive to tax elasticity assumptions.
• If tax elasticity is greater than 1.6 for CIT and PIT, and 1.5 for VAT, the residual would be zero.
• Using OECD average elasticities, the residual component was estimated at 0.27% of GDP.
• The VAT elasticity estimate of 0.95 is consistent with a single tax rate and OECD values.

Key Observations

• CIT elasticity with respect to GDP is ~1.9, indicating a strong responsiveness to economic conditions.
• PIT elasticity is ~0.7, lower than 1, possibly due to tax base elasticity being less than 1 (labor income is more stable than GDP).
• VAT elasticity with respect to private consumption ranges from 0.8 to 1. The use of private consumption as the tax base makes the estimate more reliable than using GDP.

Foreign Workers and Remittances

1. Overview

• The document also examines the role of foreign workers and remittances in the Philippines.
• Overseas Filipino Workers (OFWs) are a significant part of the economy, with a large number working abroad.
• Remittances are a major source of foreign exchange and contribute to domestic consumption and investment.

2. Characteristics of OFWs

• Stock of OFWs has been increasing over the years.
• Age distribution and income levels of OFWs vary by region.
• Occupational distribution shows a shift over time, with more OFWs in service and professional sectors.

3. Macroeconomic Implications

• Remittances have a positive impact on consumption and economic stability.
• They may help mitigate consumption volatility.
• However, remittances can also affect the capital account balance and exchange rates in the region.
• Remittances and GDP have shown a positive correlation, suggesting a supporting role in economic growth.

4. Impact on Business Cycle

• The impact of OFWs on the business cycle is analyzed, suggesting that remittances may act as a stabilizing force.
• There is a correlation between remittances and net capital inflows.
• The growth volatility of the Philippines is compared with other ASEAN countries, showing a lower volatility in the presence of remittances.

Methodology and Elasticity Estimates

• The analysis uses a decomposition approach to separate the effects of economic growth and tax administration on tax collections.
• The elasticity of tax collections with respect to the tax base is calculated using dynamic OLS and cointegration tests.
• For CIT, PIT, and VAT, the tax base is defined as:
  • CIT and PIT: GDP
  • VAT: Private consumption
• The elasticity estimates are:
  • CIT: ~1.89
  • PIT: ~0.72
  • VAT: ~0.95
• These estimates are sensitive to assumptions, particularly for CIT and PIT, and should be interpreted with caution.

Conclusion

The document highlights the importance of tax revenue in the Philippines' fiscal strategy and the role of OFWs and remittances in the macroeconomic landscape. It emphasizes the need for structural reforms in the tax system and the impact of economic cycles on tax collections. The decomposition analysis provides insights into the drivers of tax revenue growth, while the elasticity estimates underscore the complexity of tax policy effects and the sensitivity of results to assumptions.
