San Marino

San Marino applies a top marginal personal income tax rate of 35% and a corporate income tax rate of 17%. The tax burden is moderate-to-high, though various deductions and treaty networks may reduce effective rates. Capital gains are taxed at a relatively low rate of 12%, making San Marino reasonably attractive for investors and those with portfolio income. San Marino taxes residents on their worldwide income, including foreign-sourced earnings. This means income from overseas employment, investments, and business activities is subject to domestic tax rates, though double taxation treaties may provide relief. San Marino does not permit dual citizenship. Individuals acquiring citizenship here may be required to renounce their existing nationality, which has significant implications for tax residency planning and global mobility.
