The economy has a very competitive tax regime (classified by some as a tax haven). The government derives its revenue from import tariffs, VAT, licence fees, property and stamp taxes, but there is no income tax, corporate tax, capital gains tax, or wealth tax. Payroll taxes fund social insurance benefits and amount to 3.9% paid by the employee and 5.9% paid by the employer. In 2010, overall tax revenue as a percentage of GDP was 17.2%.
