Brother first of all you need to register on FBR website.
Up to 2013 FBR registration process run in e.fbr site.
After 2014 FBR introduced new registration site i.e iris.com.
Following is procedure
You enter your some minor details on iris.com site registration page including your email and mobile number, held on your name.
After 2 or 3 minutes 2 codes received at the same time on mobile number and email.
Your enter both code in registration page and your registration process completed.
After that your account in FBR site created and again you fill your complete registration form including your home address etc.
Most Important is
You must start your returns from following years.
2014/2015 financial year.
2015/2016 financial year.
2016/2017 financial year.
2017/2018 financial year.
Means you required to prepared your returns as per above sequence. If you desire to star from 2017 / 2018, it's not possible.
