St. Lucia follows the English common law system, and the tax year is the calendar year. Companies must file annual CIT returns by April 30 of the following year. Filing and compliance guide →

Real-world example: A Castries-based hotel management company with annual taxable profit of XCD 500,000 pays CIT at 30% = XCD 150,000. A small retail business with turnover of XCD 1.5 million may opt for the simplified tax regime, paying 1% of turnover = XCD 15,000 instead of the standard CIT. Compare this to Barbados (CIT 5.5%-28%) or Grenada (CIT 28%). Cross-border taxation →
