Dominica TIN — Tax Identification Number Guide

Tax Identification Number (TIN)​

The Inland Revenue Division (IRD) of the Commonwealth of Dominica issues Tax Identification Numbers to all taxpayers — individuals and legal entities — who have tax obligations within the jurisdiction. The TIN is listed in the worldwide directory of VAT and tax ID names.

TINs are not issued automatically. The IRD assigns a TIN when an individual or business representative applies for registration, or when the IRD receives third-party information indicating a registration obligation. The IRD uses SIGTAS (Standard Integrated Government Tax Administration System), an Oracle-based platform, to generate and manage all TIN records.

TIN Format​

The Dominica TIN is 7 digits: a 6-digit sequential taxpayer number followed by 1 check digit. The 6-digit base number and the full 7-digit TIN are both used in different administrative contexts — for example, registration forms may reference the 6-digit base, while tax return headers show the full 7-digit number including the check digit.

Issuing Authority​

The Inland Revenue Division (IRD) is Dominica's principal tax administration body, responsible for assessing and collecting income tax, VAT, withholding tax, and other levies. The Comptroller of Inland Revenue heads the division.

TIN Registration Process​

All businesses and individuals with a tax obligation in Dominica must register with the IRD. The registration process follows these steps:

  1. Pre-registration (companies): Foreign companies and external entities must first register with the Companies and Intellectual Property Office (CIPO) and obtain a certificate of incorporation or registration before approaching the IRD. [1]

  2. Complete the IRD registration form: The applicant fills out the IRD registration form, signed by the business owner or an authorised representative. The form captures the commencement date of business operations, which is the date from which tax obligations are calculated.

  3. TIN issued immediately: According to the IRD's guidance, the TIN is issued at the time of registration — applicants receive their number on the same visit or submission. [2]

  4. Licence determination: Upon registration, the IRD advises whether the business requires an operating licence and what type applies.

  5. Annual return obligation: All registered taxpayers must notify the IRD in writing of the commencement date of operations and submit annual returns from that point forward.

Individuals who are employed have their TINs registered through their employer's PAYE (Pay As You Earn) filing; self-employed individuals register directly with the IRD.

Key Tax Rates​

TaxRate
Corporate income tax25% on chargeable income
Personal income taxProgressive: 15%–35% (first EC$30,000 exempt)
VAT (standard)15%
VAT (hotels, diving)10%
Withholding tax (non-residents)15% on dividends, interest, royalties, technical fees
Capital gains taxNone

Personal income tax residents benefit from a resident allowance on the first EC$30,000 of annual income. Non-residents are taxed only on Dominica-sourced income. [3] [4]

VAT Registration​

Businesses whose annual taxable supplies exceed EC$250,000 must register for VAT with the IRD. This threshold was raised from EC$120,000 effective 1 September 2016. Zero-rated supplies (exported goods, medical supplies, flour, milk, rice, sugar) count toward the threshold; exempt supplies (financial services, rental payments, property sales) do not. [5]

Frequently Asked Questions​

Does obtaining Dominica citizenship through the CBI programme automatically create a tax obligation or require a TIN?​

No. Dominica's Citizenship by Investment (CBI) programme grants citizenship without requiring a single day of physical presence, and citizenship alone does not create tax residency. Tax residency is determined by a separate 183-day physical presence test under the Income Tax Act. CBI passport holders who spend fewer than 183 days per year in Dominica remain non-resident for tax purposes and are liable only on Dominica-sourced income, not worldwide earnings. A TIN registration with the IRD is required only when a person has an actual tax obligation — for example, rental income from Dominica property or employment income earned locally. [6] [7]

A foreign company wants to do business in Dominica — must it register with CIPO before it can obtain a TIN from the IRD?​

Yes. The IRD registration process requires a certificate of registration as a precondition — the TIN application form cannot be processed without it. External (foreign) companies must first register with the Companies and Intellectual Property Office (CIPO), appoint a local registered agent, and submit the required constitutional documents (Memorandum and Articles of Association or equivalent, plus the certificate of incorporation from the home jurisdiction). Only after receiving the CIPO certificate of registration can the company complete the IRD registration form and receive a TIN. Attempting to approach the IRD before CIPO registration is complete will result in the application being held pending that document. [1] [2]

At what annual turnover must a business register for VAT, and what happens if it misses the threshold?​

Businesses whose annual taxable supplies exceed EC$250,000 are required to register for VAT with the IRD. This threshold was raised from EC$120,000 effective September 1, 2016. Zero-rated supplies (such as exported goods, medical supplies, flour, milk, rice, and sugar) count toward the threshold, while exempt supplies (financial services, rental payments, property sales) do not. A business that crosses the threshold but fails to register becomes liable for VAT on all taxable sales from the date the obligation arose — the tax is owed even if it was not collected from customers — and penalties and interest apply to the shortfall. The standard VAT rate is 15%; hotel accommodations and diving activities attract a reduced 10% rate. [5] [8]

What withholding tax rate applies when a Dominica company pays dividends, interest, royalties, or technical service fees to a non-resident?​

The IRD applies a 15% withholding tax on payments of dividends, interest, royalties, and technical service fees made to non-resident individuals and entities. The payer — the Dominica-resident company or individual making the remittance — is responsible for deducting the tax at source and filing a withholding tax return with the Comptroller of Inland Revenue along with a certificate showing the gross payment and tax deducted. Failure to withhold and remit makes the payer personally liable for the undeducted amount plus penalties. No Dominica tax treaty network currently reduces this rate, so the 15% applies in full to most cross-border payments. [9] [4]

Are former Dominica IBCs (International Business Companies) still exempt from TIN registration and local corporate tax?​

No. Dominica abolished its IBC regime with effect from January 1, 2022. Companies that had been incorporated as IBCs were required to re-register as domestic companies under local legislation by December 31, 2021, or face dissolution. Re-registered companies are subject to a 25% corporate income tax on their chargeable income and must obtain a TIN from the IRD, file annual returns, and comply with economic substance requirements introduced to satisfy OECD and EU transparency standards. The abolishment followed Dominica's placement on the EU's list of non-cooperative jurisdictions in 2019 and its addition to the OECD grey list. Former IBC owners who believed their structure was still tax-free have faced unexpected compliance obligations and back-tax assessments. [10] [11]

How are Dominica TINs used under AEOI/CRS, and what must financial institutions do if an account holder's TIN is missing?​

Dominica enacted the Automatic Exchange of Financial Account Information (Common Reporting Standard) Act No. 6 of 2019, requiring Reporting Financial Institutions (banks, investment entities, insurance companies) to collect TINs for all reportable account holders and report them annually to the IRD for onward exchange with partner jurisdictions. For pre-existing accounts identified as reportable, institutions must use reasonable efforts to obtain TINs and dates of birth by the end of the second calendar year following identification. If a TIN cannot be obtained, the institution must document the reason and still submit the account with other available identifying information — omitting the TIN does not excuse the reporting obligation. Dominica began live CRS and FATCA reporting in the second half of 2021. [12] [13]
