Intimation u/s 144B

The thread already answers about how to deal with intimation u/s.144B.  I however put some additional comments with regard to s.148A/s.148 which you can think over.

Pursuant to any s.148A is a procedural safeguard for benefit of assessee which must be followed by assessing officer before issuing a notice u/s.148. In your case, since you file a reply to 148A notice(presumably objecting to reopening of assessment) and the same got rejected.  As far as department is concerned, the decision is final and you need to file a return etc. 

However, on various grounds including an order having been passed on non existent/ perverse reasons or presumptions, 148A order not dealing with your reply properly, absence of nexus between material available on record and formation of reason to believe that any income escaped assessment, you may be able to successfully challenge the order reopening the assessment itself before jurisdictional High Court.

While each case depends on facts, in my experience, I have seen that majority of orders suffer from one or the other lacunae and can be challenged before High Court to avoid assessment in toto; at occasion courts have also intervened even if assessment orders were passed.

For any proceedings before amended section 148A came in force, similar safeguards were available in form of different judicial pronouncements.

Good luck!
