Saint Lucia taxes resident companies and individuals on worldwide income at a standard 30% corporate rate, while non-residents are taxed only on Saint Lucia-source income, administered by the Inland Revenue Department. Saint Lucia's former Foreign Source Income Exemption (FSIE) regime was found to have harmful characteristics by the EU Code of Conduct Group on Business Taxation and was abolished, with amending legislation published December 30, 2020, following a 2019-2021 EU review.
Per the Inland Revenue Department's own official guidance (irdstlucia.gov.lc), the tax year runs 1 January to 31 December; corporate income tax returns are due three months after the end of the company's financial year, and individual returns are due by 31 March of the following year.
Saint Lucia's headline corporate income tax (CIT) rate is 30%.
The headline personal income tax (PIT) rate is 30%.
The standard VAT/GST (or equivalent consumption tax) rate is 12.5%.
An individual is tax resident in Saint Lucia if present for 183 days or more in a calendar year. A company is resident if registered in Saint Lucia or managed and controlled there. Resident companies and individuals are taxed on worldwide income; non-residents are taxed on Saint Lucia-source income only.
A non-resident company or individual is brought within Saint Lucia's tax net on Saint Lucia-source income, generally through a fixed place of business or dependent agent; both resident and non-resident payers must withhold tax on specified payments (royalties at 25%, interest at 15%) made to residents and non-residents alike.
Saint Lucia has no Controlled Foreign Company regime. Note separately that Saint Lucia's International Business Companies (IBC) regime and a former Foreign Source Income Exemption (FSIE) were reviewed by the EU Code of Conduct Group on Business Taxation; the FSIE regime (LC005) was found to have harmful characteristics and was abolished, with amending legislation published December 30, 2020, following a 2019-2021 EU review process.
No statutory thin capitalization ratio or interest-limitation rule was identified in available sources.
Saint Lucia 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 Lucia having no Controlled Foreign Company regime; the abolition of the FSIE regime described above was itself an EU-driven anti-avoidance reform rather than an anti-hybrid measure in the ATAD2 sense.
No domestic FBAR-equivalent regime requires Saint Lucia residents to separately disclose foreign financial accounts. Saint Lucia is a CRS participating jurisdiction, having signed the CRS Multilateral Competent Authority Agreement in October 2015 with exchange beginning September 2018. US persons remain independently subject to FinCEN Form 114 (FBAR) and potentially Form 8938 regardless of Saint Lucia's own rules.
Dividend income, including intercompany dividends, is exempt from taxation in Saint Lucia without a stated minimum-ownership or holding-period threshold; gains from the sale of assets, including shares, are similarly tax-free unless the gains arise from ordinary business activity, in which case they are included in the corporate income tax base as trading profit rather than capital gain.
A dedicated unilateral foreign tax credit mechanism is not confirmed in available primary sources. Saint Lucia's only comprehensive tax treaty is the CARICOM multilateral agreement; outside that relationship, relief from double taxation for Saint Lucia residents with foreign-source income depends on the country's 15 Tax Information Exchange Agreements, which provide for information sharing rather than double-tax relief.
Saint Lucia has one double tax agreement: the CARICOM multilateral treaty. There is no separate bilateral treaty network beyond this multilateral instrument, and no US tax treaty exists.
