Saint Kitts and Nevis taxes resident companies on worldwide income at a flat 33% corporate rate (increased in recent years), while non-resident companies are taxed only on Saint Kitts and Nevis-source income, administered by the Inland Revenue Department. Saint Kitts and Nevis levies no personal income tax at all, on either residents or non-residents.
Per the Inland Revenue Department's own official guidance, the Corporate Income Tax Return is due 3.5 months after the company's fiscal year-end (for example, 15 April for a 31 December year-end); quarterly installment payments are separately due 15 March, 15 June, 15 September, and 15 December.
33% standard rate on worldwide income for resident companies (non-residents taxed on Saint Kitts and Nevis-source income).
0% - no personal income tax.
17% standard VAT - the highest standard rate in the Eastern Caribbean.
An individual is tax resident in Saint Kitts and Nevis if present for 183 days or more in a calendar year. A company is resident if incorporated in the Federation or centrally managed and controlled there. Resident companies are taxed on worldwide income; non-resident companies are taxed only on Saint Kitts and Nevis-source income. There is no personal income tax for either residents or non-residents, so the residency test primarily matters for corporate tax, withholding tax administration, and Citizenship by Investment (CBI) program purposes rather than for triggering any personal tax liability - CBI passport holders are not automatically tax resident and are not taxed simply by virtue of holding citizenship.
A non-resident company is brought within Saint Kitts and Nevis corporate tax where it derives income from a Saint Kitts and Nevis source, generally through a fixed place of business or dependent agent; payments to non-residents without a qualifying local presence, including dividends, interest, and royalties, are instead subject to a 15% withholding tax.
Saint Kitts and Nevis has no Controlled Foreign Company regime. Tax residents may own offshore companies without those entities' income being attributed back to the resident owner under domestic Kittitian/Nevisian law.
No statutory thin capitalization ratio or interest-limitation rule was identified in available sources.
Saint Kitts and Nevis classifies entities according to its own domestic company and tax law rather than offering an elective check-the-box system, and no anti-hybrid mismatch regime addressing double-deduction or deduction-without-inclusion outcomes has been identified, consistent with Saint Kitts and Nevis having no Controlled Foreign Company regime at all.
No domestic FBAR-equivalent regime requires Saint Kitts and Nevis residents to separately disclose foreign financial accounts. Saint Kitts and Nevis is a CRS participating jurisdiction, having signed the CRS Multilateral Competent Authority Agreement in February 2016 with exchange beginning September 2018, and enacted the Common Reporting Standard (Automatic Exchange of Financial Account Information) Act in December 2016. US persons remain independently subject to FinCEN Form 114 (FBAR) and potentially Form 8938 regardless of Saint Kitts and Nevis's own rules.
No participation exemption regime for dividends or capital gains from a qualifying subsidiary was identified in Saint Kitts and Nevis tax law, confirmed directly by a primary tax-guide source stating the jurisdiction has 'no participation exemption' and no holding company regime, though International Business Companies benefit from a special separate tax regime rather than the general corporate rules.
Foreign tax credits are generally not applicable in Saint Kitts and Nevis unless the counterparty jurisdiction has a tax agreement with Saint Kitts and Nevis (through the CARICOM multilateral treaty or one of the country's bilateral treaties), or the taxes were paid in a British Commonwealth country that provides reciprocal relief; outside those relationships, foreign tax paid generally does not generate a credit against Saint Kitts and Nevis tax.
Saint Kitts and Nevis has double tax agreements with fellow CARICOM members (Antigua and Barbuda, Belize, Dominica, Grenada, Guyana, Jamaica, Saint Lucia, Saint Vincent and the Grenadines, and Trinidad and Tobago) via the CARICOM multilateral agreement, plus separate bilateral treaties with Denmark, Norway, Sweden, San Marino, and the United Kingdom. No US tax treaty exists. Customs duties do not apply to goods imported from other CARICOM member states.
