Rationalizing the Canadian Income Tax System

The Canadian tax system is based on principles informed by the Carter report, and these principles have been challenged as circumstances have changed and ideas about tax policy have evolved. The personal tax system pays only lip service to the comprehensive income tax ideal, and the corporate tax is designed as a complement to a comprehensive tax system that does not exist. Canadian policy makers face the unprecedented challenges of (1) globalization, (2) an economy increasingly based on services and technology, and (3) growing inequality of income, wealth, and opportunity. Modern principles of tax design are reflected in recent tax reform proposals recommended by the Mirrlees review in the United Kingdom. Major tax reforms have been undertaken in other member countries of the Organisation for Economic Co-operation and Development. Some piecemeal innovations in tax policy have been implemented in Canada, such as registered retirement savings plans, tax-free savings accounts, the goods and services tax/harmonized sales tax, and refundable tax credits, but these measures have not been coordinated. The corporate tax structure has changed only modestly. This paper explores options for feasible reform of the Canadian tax system that might enhance equity and efficiency.
