Input on gst

No you cannot...

ITC on Works Contract is BLOCKED u/s 17(5) of the CGST Act 2017.

you cannot claim ITC on expenses capitalised to Building account, but the expense of Revenue Nature which is not capitalised to building the ITC can be claimed.
(as per explanation under section 17(5))

A straight answer to the question would be 'No'. However there is a double taxation involved in this taxation. Assessee is not allowed to take ITC and liable to Pay GST on output supply.

A similar case was taken up by Orissa High court. You can rely on the same and litigate your stand point as you are suffering double taxation.
