El Salvador optimizes its immigration policy, allowing temporary residents to enjoy a 0% tax rate on Bitcoin earnings and overseas income.

According to Mars Finance, El Salvador is continuously optimizing its immigration system to attract high-net-worth foreign talent and capital (including families). Under Decree No. 531, which came into effect on March 31, 2026, the residency requirement for temporary residents has been reduced from nine months of residence per year to only 90 days cumulatively or continuously per year. This adjustment primarily targets entrepreneurs, investors, and remote workers who require frequent cross-border travel. El Salvador offers one of the most attractive tax systems in Latin America for individuals with overseas income. The country operates on a territorial tax system, meaning that only income generated within El Salvador is taxable. A significant income tax reform in 2024 further clarified this: overseas income is exempt from income tax for both residents and non-residents. This means that freelancers and remote workers (such as content creators, developers, and entrepreneurs with overseas income) can enjoy a 0% Salvadoran income tax on their overseas income, with no limit on the amount. Furthermore, under El Salvadoran law, capital gains related to Bitcoin are not taxed, and the country also does not levy wealth tax, inheritance tax, or gift tax. The real focus is on whether the individual's country of origin recognizes this arrangement; because most countries do not usually give up their right to tax their tax residents easily and often conduct rigorous reviews and pursuits on tax attribution issues.
