An Assesse is registered in work contract as a civil contractor at delhi, he gots a contract for construction in some other state for construction. He is registered as a work contractor (composition Scheme) Delhi, if he is doing inter state work which act will apply to him.
CST OR WCT OF RESPECTIVE STATE IN WHICH WORK IS CARRIED ON, MEANS WILL HE HAVE TO APPLY FOR TIN NO. OF RESPECTIVE STATE.
AS PER MY KNOWLEDGE CONTRACTOR GETS REGISTERED THEM SELVES FOR WORK CONTRACT IN THE RESPECTIVE STATE .
BUT WHY NOT CST. I THINK CST IS GOOD OPTION.
