Partner ship nil itr

Respected Sir,

My Question is If a Partnership Firm Apply Pan Card in F/Y 2017-18 and recived Pan Card in same F/Y.  But Partner Ship Firm Registered in GST in April (F/Y 18-19) and After Then Open Firm Current A/c.

Is it Still Compulsary for the Partnership Firm to Submit a Nil Income Tax Return A/y 18-19. and  Sir That is Possible IT Return Submit Without Bank Current A/c Number.
