Tax competition is often discussed through headline rates. For globally mobile investors, entrepreneurs and wealthy families, that is only part of the story. A more revealing measure is the tax-to-GDP ratio: how much a government collects in taxes relative to the size of its economy.
The latest figures show a wide gap between high-tax social democracies, mid-ranking financial centres and jurisdictions whose appeal rests partly on lighter tax treatment, administrative simplicity or business-friendly regimes.
“The lesson is simple: tax-friendly does not always mean low revenue”
Across the OECD, the average tax-to-GDP ratio rose to 34.1% in 2024, its highest recorded level. Denmark remained at the top of the OECD table, followed by France and Austria. Eurostat’s wider European data show a similar pattern, with Denmark, France and Belgium collecting the highest tax and social contribution revenues relative to GDP.
Yet the picture becomes more nuanced when viewed through the lens of wealth mobility. Some jurisdictions widely known for attracting international business and private capital are not especially low-tax in aggregate. Luxembourg, for example, remains high in the European table. Cyprus sits well above Malta. The United Kingdom, including London, is broadly around the OECD average rather than a low-tax outlier.
Malta is more interesting. Its tax burden rose sharply in 2024 to 29.3% of GDP, still among the lowest in the EU, but no longer negligible. The rise was driven mainly by stronger income-tax receipts, including corporate tax. Ireland remains lower, though its ratio is affected by the unusually large GDP denominator created by multinational activity.
At the lower end, Gibraltar and the UAE better illustrate the “tax advantage” proposition. Gibraltar’s tax-to-GDP ratio is estimated at around 18%, while World Bank data place UAE tax revenue at just 0.6% of GDP on a narrower central-government tax measure. The British Virgin Islands are harder to rank cleanly, but official budget figures show a model heavily supported by taxes, fees and financial-services-related revenue rather than broad-based income taxation.
The lesson is simple: tax-friendly does not always mean low revenue. Some centres attract capital through certainty, treaties, lifestyle and specialist regimes rather than a small state take. Others operate a genuinely light-tax model. For wealthy migrants seeking greener pastures, the question is no longer simply “how low is the rate?” but “what does the whole fiscal proposition look like?”
