Anguilla Tax Identification Number (TIN) Guide
Tax Identification Number
Tax Identification Numbers (TINs) are assigned to individuals and entities upon registration with the Inland Revenue Department (IRD), which serves as Anguilla's tax administration authority responsible for tax collection and law enforcement. TINs typically remain unchanged and do not undergo frequent renewal.
There has been a recent modification to the TIN structure concurrent with the introduction of the new tax administration system. In the past, taxpayers were provided with Customer Identification Numbers and Enterprise Numbers for unique identification. The TIN now functions as a singular identifier for all tax types and uniquely identifies each registered individual or entity at the IRD.
The IRD enforces mandatory use of TINs across all commercial transactions. Since October 2022, businesses must include their TIN on all invoices, Customs declarations, banking transactions, and government applications. Missing or mismatched TINs result in rejected claims and enforcement action.
Format
Anguilla TINs are 10-digit numeric codes automatically generated by the tax administration system. The structure is:
| Position | Description |
|---|---|
| Digit 1 | Prefix: 1 = Individual, 2 = Non-Individual (business) |
| Digits 2–9 | Unique sequential identifier assigned by the system |
| Digit 10 | Check digit for validation |
Regex pattern: ^[12]\d{8}\d$ (10 digits, starting with 1 or 2)
Examples:
- Individual TIN:
1000000001— begins with prefix1 - Business TIN:
2000000001— begins with prefix2
The check digit is automatically calculated by the IRD system. There is no publicly documented checksum algorithm (such as Luhn), so external validation should rely on the prefix and length rules, with full validation deferred to the IRD portal.
Issuing Authority
The Inland Revenue Department (IRD) issues and maintains all TINs. TINs are generated automatically when a taxpayer registers for the first time. Registration is required for:
- Any person obtaining a business licence
- Any person applying for a driver's licence
- Any person applying for a Certificate of Good Standing
- Any entity registering for GST
The IRD is located at the Former NBA Building, 1st Floor, The Valley, Anguilla. Phone: +1 264 497 8334. The public register of GST-registered taxpayers (with TINs) is published monthly at ird.gov.ai.
GST Framework
Anguilla introduced Goods and Services Tax (GST) on 1 July 2022 at a standard rate of 13%. Key compliance parameters:
| Parameter | Detail |
|---|---|
| Standard rate | 13% |
| Registration threshold | XCD 300,000 annual taxable turnover |
| Mandatory registration | Accommodation suppliers (regardless of turnover) |
| Return filing deadline | 20th of the month following the tax period |
| Late payment interest | 1% per month on unpaid tax |
Businesses that exceed the XCD 300,000 threshold must register proactively. Operating above the threshold without registration exposes the entire turnover to back-assessed GST plus penalties.
Economic Substance Requirements
Since January 2019, Anguilla companies conducting certain "relevant activities" must satisfy economic substance requirements — regardless of whether Anguilla levies corporate income tax. Relevant activities include: banking, insurance, fund management, financing and leasing, headquarters, shipping, intellectual property, distribution, and service centre business.
Compliant entities must demonstrate:
- Adequate physical presence (office, equipment) in Anguilla
- Sufficient qualified employees in Anguilla
- Core income-generating activities carried out locally
- Mind and management decisions taken in Anguilla
Annual economic substance returns are filed with the Registrar. Non-compliance penalties start at USD 5,000 for a first offence and scale to USD 25,000, with potential strike-off for persistent failure.
Cross-Border and AEOI Obligations
Anguilla participates in the OECD Common Reporting Standard (CRS) and FATCA. Financial Institutions operating in Anguilla must:
- Register on the Anguilla AEOI Portal (one-time, mandatory since 2024)
- File annual CRS returns by 31 May each year for the prior calendar year
- Submit nil returns if no reportable accounts exist — nil filing is mandatory even for zero-account periods
Investment funds, trusts with custodians, and IBCs holding financial assets for third parties are all potential Reporting Financial Institutions and must confirm their classification.
Frequently Asked Questions
My GST input tax credit claim was rejected at Customs — why does the TIN matter on the import declaration?
When goods are imported into Anguilla, GST paid at the border is recoverable as an input tax credit — but only if your TIN appears on the Customs declaration. The IRD updated the ASYCUDA World platform in May 2022 to link TINs across both the Customs and Revenue departments. If your TIN is absent or mismatched on the import entry, the IRD will reject the input tax credit claim outright and you absorb the GST as a cost. [1] [2] Ensure your registered TIN is stored in your customs broker's system before any shipment arrives.
Anguilla has no corporate tax — does my Business Company still need to file anything with the IRD?
The "no tax" reputation is accurate for income and profits, but Anguilla companies conducting relevant activities have been subject to economic substance requirements since January 2019. Every in-scope entity must file an annual economic substance return with the Registrar and demonstrate adequate physical presence, qualified employees, and core income-generating activities conducted locally. Failure to file can result in fines of USD 5,000 to USD 25,000 for a first offence and up to USD 100,000 for each subsequent year of non-compliance, plus potential striking-off. [3] [4]
Does Anguilla's GST registration threshold apply to foreign businesses selling services into Anguilla?
The standard GST registration threshold is XCD 300,000 in annual taxable turnover. Anguilla's GST Act charges GST on supplies made in Anguilla, so foreign suppliers whose services are consumed in Anguilla fall within scope once that threshold is crossed. Accommodation suppliers are mandatorily registered regardless of turnover. The GST rate is 13%, returns are due by the 20th of the month following the tax period, and late remittance attracts penalties plus 1% monthly interest. [5] [6] Foreign businesses approaching this threshold should register proactively — operating unregistered above the limit exposes the full turnover to back-assessed GST plus penalties.
Since 2024, must every Anguilla financial institution register on the AEOI portal even with no reportable accounts?
Yes. The CRS Regulations were amended in 2024 to require every Anguilla Financial Institution — except specifically exempted categories — to register on the Anguilla AEOI Portal. Registration is a one-time obligation, but nil returns are now mandatory annually for each Reporting FI even if no account holder information needs to be exchanged. The annual filing deadline is 31 May for the prior calendar year's reporting period. [7] [8] Investment funds, trusts with custodians, and IBCs holding financial assets for third parties are all potential Reporting FIs and should confirm their classification before the annual deadline.
As an employer in Anguilla, what payroll levy obligations require a TIN and when do penalties start?
Every employer with staff earning more than EC$2,000 per month must withhold and remit the Universal Social Levy (USL) at 3% of the employee's gross monthly salary up to EC$12,000, matched by a 3% employer contribution on the same cap. Self-employed persons pay 6% on gross earnings above EC$2,000 per month. Returns and payments are due within 10 days of the end of each calendar month, and the employer's IRD-registered TIN must appear on all filings. Late filing attracts EC$50 per day up to EC$2,000 per month, plus 1% monthly interest on unpaid amounts. [9] [10]
Can a business operate without a TIN in Anguilla after the October 2022 enforcement notice?
No. The IRD's October 2022 enforcement notice made TINs mandatory for all commercial transactions — including invoices issued to customers, Customs import and export declarations, applications for business licences, and transactions with banks and government departments. Businesses that continue operating without a TIN or that use an incorrect TIN risk having their GST credits denied, business licence applications rejected, and banking transactions flagged. [1] [11] Any business that obtained a licence prior to the new tax system must confirm their TIN has been migrated from the old Customer Identification Number format.
