Frequently Asked Questions

How much does TIN registration cost?

TIN registration is free. There are no official charges for obtaining a TIN from JTB or NRS (Formerly FIRS). Be wary of anyone requesting payment for TIN registration.

Can I have more than one TIN?

No, each individual or entity should have only one TIN. If you have multiple TINs, contact the tax authority to harmonize them into one.

Do I need a TIN to start a business?

Practically, yes. While you can register with CAC without a TIN, you'll need one to open a corporate bank account and fulfill tax obligations.

How long is a TIN valid?

A TIN is valid for life (individuals) or the life of the company. It doesn't expire but must be kept active through proper tax compliance.

Can I use my individual TIN for my business?

For sole proprietorships/business names, your individual TIN is linked to the business. For limited companies, a separate company TIN is required.

What if my company TIN application is rejected?

Review the rejection reason, correct any issues, and reapply. Common reasons include incomplete documents or discrepancies in information.
