Dear Professional friend,

Can you please help me on the following query :

1. if we sale the goods, where the MVAT is NIL, from Mumbai to Bhopal to an unregistered dealer what rate will be charged as per Maharastra Sales Tax Act.
2. if we sale the goods, where the MVAT is NIL, from Mumbai to Bhopal to an registered dealer against Form "C" what rate will be charged as per Maharastra Sales Tax Act.
