10 lakh limit.

But this is the unjustified with the recipient of those areas because their already low purchasing power if tax imposed on supply then reduce the purchasing power and then supplier also face the struggle for sale goods and state are not developed I think government requires to increase limit above 20 lakh so more suppliers are supply more in those area and develop the state. And recipients get goods or services at lower rate so increased their purchasing power and develop the overall recipient, supplier and state.

Ha Ha Ha.... Dear this our thoughts...

But, Rule is different between Normal category and Special category Before and After GST...

 

Why not You think about Govt's view...? Think Only Business peoples view...

Govt will collect Tax and serve to Peoples. Bcoz, Lesser value of Transactions...
