The 2025 International Tax Competitiveness Index (ITCI), published by the Tax Foundation and based on data from the Organisation for Economic Co-operation and Development (OECD), provides a comprehensive look at how 38 OECD member countries design their tax systems to attract investment and support economic growth.
In a world where capital and business operations move across borders faster than ever, the structure of a tax system—not only its rate—has become a key factor for competitiveness. For international companies and financial operators, tax policy affects where to locate, reinvest, and manage cross-border cash flows efficiently.
According to the Index, Estonia retains the world’s most competitive tax system for the 12th consecutive year. Its 22 percent corporate tax applies only to distributed profits, it maintains a flat personal income tax, and exempts 100 percent of foreign profits.
The other top performers are:
1️⃣ Estonia
2️⃣ Latvia – which follows Estonia’s model of taxing distributed profits only.
3️⃣ New Zealand – simple, broad-based taxes and no capital-gains, inheritance or financial-transaction taxes.
4️⃣ Switzerland – low corporate and consumption taxes and efficient cross-border tax rules.
5️⃣ Lithuania – a 17 percent corporate rate and strong cost-recovery provisions for investment.
At the other end of the spectrum, the least competitive tax systems belong to:
The average combined top corporate income-tax rate across OECD countries stands at 24.2 percent in 2025.
The lowest statutory rates are found in Hungary (9 percent), Ireland (12.5 percent), and Lithuania (15 percent).
Countries that combine moderate tax rates with simple structures and effective cost-recovery rules tend to perform best in the Index.
Tax competitiveness influences where companies establish headquarters, hold treasury functions, and reinvest capital.
For globally oriented firms, understanding tax design is essential for maintaining operational efficiency and sustainable growth.

Afraid your money might disappear into a black hole? Sent, and then… silence. No confirmation, no way to know where it is. When a transfer crosses borders, that silence shouldn’t be part of the deal. International payments. Nothing left in the dark. Few paintings have unsettled and fascinated in equal measure like Kazimir Malevich’s Black […]
Cross-border payments across Africa are being reshaped in real time. And ahead of the Africa Fintech Summit in Kigali, one question moved to the centre of the conversation: not whether stablecoins will play a role in moving money across the continent, but under whose rules they will do it. In a pre-summit discussion, industry leaders […]
