This paper investigates the design of tax structures to promote economic growth. It suggests a “tax and growth” ranking of taxes, confirming results from earlier literature but providing a more detailed disaggregation of taxes. Corporate taxes are found to be most harmful for growth, followed by personal income taxes, and then consumption taxes. Recurrent taxes on immovable property appear to have the least impact. A revenue neutral growth-oriented tax reform would, therefore, be to shift part of the revenue base from income taxes to less distortive taxes such as recurrent taxes on immovable property or consumption. The paper breaks new ground by using data on industrial sectors and individual firms to show how redesigning taxation within each of the broad tax categories could in some cases ensure sizeable efficiency gains. For example, reduced rates of corporate tax for small firms do not seem to enhance growth, and high top marginal rates of personal income tax can reduce productivity growth by reducing entrepreneurial activity. While the paper focuses on how taxes affect growth, it recognises that practical tax reform requires a balance between the aims of efficiency, equity, simplicity and revenue raising.
