Saint Lucia TIN number guide
Tax Identification Number (TIN)
The Tax Identification Number (TIN) is a numerical code allocated to individuals and entities upon request. These codes are systematically generated in sequential order and serve as universal identifiers for all tax obligations. Each TIN is combined with a two-digit tax type ID to form a unique tax account number for every entity. For instance, if a corporation holds TIN 1234, its VAT account number would be 123427, and its corporate tax account number would be 123402.
Changes in business circumstances may prompt a TIN alteration. For example, if a business transitions from a sole proprietorship to a corporation, a new TIN would be issued. However, TINs assigned to individuals remain unchanged under normal circumstances. The TIN consists of a maximum of six (6) digits

Frequently Asked Questions
Does holding Saint Lucia citizenship through the CBI programme make me a tax resident?
No. Saint Lucia citizenship acquired through the Citizenship by Investment (CBI) programme does not automatically confer tax residency. Tax residency is determined by physical presence: an individual becomes a Saint Lucia tax resident only by spending 183 days or more in the country during the tax year, or by maintaining their permanent place of residence there across consecutive years. CBI investors who do not meet these thresholds remain non-residents and are not taxed on worldwide income — only on income with a Saint Lucia source. Confirm residency status with the IRD before making any filings. [1] [2]
At what turnover must a foreign business register for VAT, and is there a separate threshold for digital services?
Any person conducting a taxable activity in Saint Lucia must register for VAT with the IRD within ten working days once taxable supplies meet or are reasonably expected to meet EC$400,000 in any 12-month period. Saint Lucia's VAT Act does not currently carve out a separate lower threshold for digital or electronic services supplied by non-residents — the same EC$400,000 standard applies. Businesses supplying only exempt goods or services do not need to register regardless of turnover. Voluntarily registered businesses below the threshold are still bound by all VAT filing obligations once registered. [3] [4]
What withholding tax rate does a foreign supplier face on royalties, fees, and interest paid from Saint Lucia?
Payments of royalties and management fees from a Saint Lucia payer to a non-resident are subject to 25% withholding tax. Interest paid to a non-resident is withheld at 15%. Both rates drop for residents of other CARICOM member states: 15% on royalties/management fees and 10% on interest. Dividends paid to non-resident shareholders carry no withholding obligation. The payer is responsible for deducting and remitting the tax to the IRD; failure to withhold makes the payer liable for the undeducted amount. No withholding tax treaty network currently reduces these rates further for most trading partners. [5] [6]
What is the difference between a TIN and a Tax Account Number, and which one do I quote on invoices?
A TIN is the core six-digit identifier assigned once to a taxpayer and never reused. A Tax Account Number is the TIN concatenated with a two-digit tax-type suffix that identifies a specific obligation: suffix "02" for corporate income tax, "27" for VAT. When invoicing for VAT purposes, you must quote your VAT Tax Account Number (e.g., 00123427), not the bare TIN, because the IRD links payments and returns to the full account number. Quoting only the TIN on a VAT invoice can cause the IRD's system to fail to match the return, leading to apparent non-filing notices even when you have filed and paid. [7] [8]
Why is a tax clearance letter required before collecting government contract payments, and how quickly can I get one?
Saint Lucia's public procurement rules require contractors and suppliers to produce an IRD tax clearance letter confirming they are registered with the IRD, have filed all required returns for the past six years, and owe no outstanding tax before government entities will release payments. Without a current clearance letter, payment can be withheld indefinitely even after work is completed. Requests must be submitted on company letterhead signed by an authorised officer. The IRD processes clearance letters within 48 hours once all conditions are met — meaning any arrears or unfiled returns must be resolved first, which is the most common cause of delay. [9] [10]
