Dual Income Taxation: A Promising Path to Tax Reform for Developing Countries

The dual income tax combines a progressive tax on labor income and a lower flat tax on income from capital. Unlike flat tax systems, a dual income tax provides developing countries greater flexibility in addressing tax competition while retaining progressivity. Countries could use the move to a dual income tax system not just as an opportunity to rationalize the taxation of income from business operations and investment but also as a vehicle for broader reform of their tax systems.
