GST on House Rent + Commussion

1) Assuming your commission income is not exempted under GST, you are required to take registration.

2) On commission income you have to pay GST.

Thanks for reply.
can u please explain few points.
i am showing this rental income under the head Income From House Property since Renting a house is not my business turnover and not a supply for me..
still it will be added in turnover??

Under GST the term "business" includes admission, for a consideration, of persons to any premises.Thus,  though the income from Renting of Residential dwelling is reported under the head Income from House property under Income Tax Act,1961, renting of residential dwelling will be considered as business.Further, if renting of residential dwelling is not to be considered as business , there was no need for govt to exempt renting of residential dwelling from GST.

Ok got it
thanks for reply.
one last query

my monthly rent 66k is fixed per month but commission depends on business.
so if i get the commission of 15 lacs in April and every month only rent income of 66k then i will cross the threshold limit of 20 Lacs in October.
i need to register under GST in October and from October to march only rent income will come which js exempt so don't need to pay GST in that case.

m i right???

Yes you are right 

Thanks Alottt
