RCM on interstate supply where supplier is small

unregiste can't make interstate supply..

threshold limit is not applicable for interstate supply...means dealer making interstate supply has to take reg even if his T.O. is 1rs

MEANS,,I'LL GIVE U EX: ONE OF MY CLIENT PURCHASED FROM MP WORTH RS.2L GST RATE 18 % (UNREGISTER DEALER ). THEY PAY TAX ON RCM ON PURCHASE (WITHOUT CONSULTING US). 

RCM IS NOT THE ISSUE HERE . IMP IS INTERSTATE PURCHASE FROM UNREGISTER DEALER (NOT ALLOWED IN GST )

WHAT GST LAW SAYS PERSON MAKING INTERSTATE SUPPLY HAS TO REGISTER UNDER GST EVEN IF T.O IS BELOW 20L.
