You need to take registration if you cross the threshold of Rs. 150 lacs. After crossing 90 lacs you just need to intimate the department. If your turnover will cross 150 lacs in the first quarter of the year only, then take a registration before hand. But if it will cross after 6-7 months then it is better to wait. Because the moment you take the registration, whether you are liable to duty payment or not, you will have to file the return, even if it will be a nil return.
