What is an NTN, and how do you register?

An NTN is your National Tax Number. For individuals, your CNIC number is used as your NTN, but you still need to be registered on FBR IRIS before you can file a return.

What you need to register

  • CNIC copy
  • A mobile number registered in your own name
  • An email address you can access

Businesses and companies

Businesses, AOPs and companies are registered separately and need different documents. Message me with your business type and I will tell you exactly what to prepare.

Registration with me

I register you free when you file your return with me. A stand-alone registration is quoted on request.
