Dear Demz
Section 10(1) of the Companies Income Tax Act (as amended by the Finance Act, 2019) provides that:
"Every company shall have a tax identification number (TIN) which shall be displayed by the company on all business transactions with other companies and individuals and on every document, statement, returns, audited account and correspondence with revenue authorities, including the Federal Inland Revenue Service, Ministries and all Government Agencies."
In line with this provision, all entities, including foreign customers engaging in business transactions with Nigerian companies, are required to obtain a Nigerian TIN. Foreign customers who do not currently have a TIN may approach the International Office of the Federal Inland Revenue Service (FIRS) to obtain one.
This ensures compliance with the law and enables their transactions to be validly captured under the e-Invoicing framework.
