can any one tell ITC-4 in gst applicable to whom?

Hi,
I own a newly founded company (LLP) which offer IT services.
Should I charge my client GST for 18% or Can I skip?
I read somewhere that GST is applicable if the annual turnover is Rs. 20 Lac or above.
Please guide me.

Thanks

i m a woman enterprenuer, but now my business is closed due to the industry operations closed where my work order was given to my firm. There is a dispute between service tax department and my firm about the amount paid to department by me after receiving it from my principal industry where i was regd to execute their work order. The s tax deptt says that amount deposited in govt treasury is less than required amount which i had to deposit. I have statement from the closed industry accounts office to pay as 55000/= rupees to pay by me as on closure date but the department says it is about more than 3 times of that figure. What to do now? What legal relief i can get from indian law prevailing as on date?
