15-G & 15-H

Friends. I have following doubts about form no. 15-G and 15-H. Kindly solve.

1. Only individual tax-payers can submit these forms or non-individuals can also go for it like AOPs or BOIs?

2. These forms can be used to avail non-deduction of TDS in cases where its regarding any interest payments or it can be used for other sorts of payment too?

3. We have to submit it into two copies to the deductor. Am i correct in that?

4. If we receive any of these forms then do we have to forward any copy of it to any ITOs? I am not sure about this.

Kindly reply.

Thanks & regards
