When turnover of agents will be added to that of the principal for registration?

Is there any concept of area based exemption under GST?

Whether a separate GSTIN would be allotted to a registered person for deducting TDS (he has PAN and TAN as well)?

If I register voluntarily though turnover is less than 20 Lakhs, am I required to pay tax from 1st supply I make post registration?

If someone trades only 0% GST items (grains, pulses) then is it necessary to register for GST, if the turnover exceeds ₹20 lacs?

Please tell if rental income up to 20 lacs attracts GST or attracts any other charge?
