The variety of approaches to taxation among OECD (Organisation for Economic Co-operation and Development) 37 countries creates a need to evaluate these systems relative to each other. For that purpose, the International tax competitiveness index (ITCI) was developed – a relative comparison of OECD countries’ tax systems with respect to competitiveness and neutrality.
According to research from the OECD, corporate taxes are most harmful for economic growth, with personal income taxes and consumption taxes being less harmful.
Taxes on immovable property have the smallest impact on growth.
There are many factors unrelated to taxes which affect a country’s economic performance. Nevertheless, taxes play an important role in the health of a country’s economy.
Countries that rank poorly on the ITCI often levy relatively high marginal tax rates on corporate income.
