"Majority of the supplies would be of exempted catagery. so if I go for composition scheme I have to pay GST for aggregate turnover."
It is not very much clear from the wordings, whether the composition tax shall be levied on taxable turnover only or over aggregate turn over.
Read: == The taxable persons having Aggregate annual turnover of Rs. 50 lakhs are proposed to be made eligible for Composition levy. ==The amount payable in lieu of tax payable will not be less than 1% of the turnover during the year.
+++ Not less than 1% of the turnover will be payable in lieu of GST.
a. From the wording in section it is not clear that whether amount will be calculated on aggregate turnover or taxable turnover.
b. In case it is calculated on aggregate turnover than it will be a non workable proposal for a taxpayer having exempt and non taxable income.
In second case it would be advisable, not to opt for composition scheme, and charge normal GST.
