TF – International Tax Competitiveness Index, 2023

The International Tax Competitiveness Index ranks OECD countries' tax systems based on their competitiveness and neutrality. A well-structured tax code can promote economic development and generate sufficient revenue for government priorities. In recent years, many countries have reformed their tax codes, reducing marginal tax rates on corporate and individual income. However, not all changes have had a positive impact, as some countries have increased corporate income tax rates. Additionally, there have been improvements in corporate tax bases in some countries, while others have become less competitive. Temporary changes to tax systems have also been implemented due to the COVID-19 pandemic. As countries face revenue shortfalls, they need to consider how to structure their tax systems to support economic recovery and raise revenue. The International Tax Competitiveness Index provides a way to compare and evaluate these tax systems relative to each other.
