10 Essential Questions About TIN in Antigua and Barbuda
Common Questions
1. What is a TIN in Antigua and Barbuda?
In Antigua and Barbuda, the Tax Identification Number (TIN) is the fundamental unique identifier used by the Inland Revenue Department (IRD) to track all tax obligations, including Corporate Income Tax, ABST, and Property Tax.
It is often used in conjunction with a Tax Account Number (TAN), which acts as a sub-identifier linking the entity to a specific tax type (e.g., an ABST account vs. an Unincorporated Business Tax account). Without a valid TIN, a business cannot legally issue tax invoices or interact with the ASYCUDA customs system.
