Outline of the presentation • Main trends in OECD countries • Main types of PIT systems • Issues when choosing a PIT system • Making Work Pay Policies • Conclusion
Main Trends in the OECD • Reduced share of PIT revenues since 1990 • Continued reduction of PIT rates and flatter rate schedules • Move towards semi-dual income tax systems • Increased use of tax credits and “Making Work Pay Policies” • Continued move towards individual taxation, but family benefits deliveredthrough the tax systems in some countries
Main types of PIT systems • Comprehensive Income Tax* Progressive rate schedule on income above basic allowance* Often combined with extensive tax expenditures • Dual Income Tax* Single tax rate on income above basic allowance, combined with progressive taxation of labour and pension income* Combined with a limited number of tax expenditures • Flat Income Tax* Single tax rate on net income above basic allowance* Very limited number of tax expenditures

The choice of a PIT system The key issues are: • Simplicity • Efficiency • Equity • Tax Compliance
Simplicity * Complexities mainly due to definition of tax bases, not rate schedules* Complexities from differences in rate schedules due to income shifting opportunities * Withholding at source reduces actual complexity for personal taxpayers* Compromised by non-tax objectives (e.g., earned-income tax credits)
Efficiency * Tax distortions due to high tax rates and non-neutralities in the tax base* Uncertain effect of move from progressive to single rates schedule, if reform is revenue-neutral* Base-broadening will (normally) increase economic efficiency, and even more so if combined with lower rates
continued 2 Equity - Horizontal equity requires equal treatment of equals- Progressive rates in theory better for vertical equity for a given tax base, but tax expenditures also matter- Base broadening increases horizontal equity, and may also increase vertical equity
Tax Compliance - Incentives for tax avoidance increase with the tax rate- Opportunities for tax avoidance increase with tax expenditures and income shifting possibilities - Withholding at source reduce opportunities for tax avoidance
Making Work Pay Policies Main objectives: • To increase employment • To increase incomes of disadvantaged groups • Positive effects on employment (entrance into the labour market) and incomes of low-income households • Potentially negative effect on the number of hours worked over certain earnings ranges
Conclusion Simplicity, in the form of a broad base with a basic exemption but few other deductions, is the key for any type of income tax system. It promotes: • Efficiency • Equity • Compliance
