The Definition of Aggregate Turnover under section 2(6) of the Act provides that all "TAXABLE SUPPLIES" along with exempted and other supplies, except supplies on which tax is to be paid on reverse charge basis, shall be considered for the calculation of the limit of Rs. 20 lakhs.
Does "TAXABLE SUPPLIES" only include Outward supplies, or it may be either outward as well as inward supplies, as the term supply is not defined in the GST law. Also, Taxable supply includes any supply on which tax is chargeable, so does the definition of Aggregate Turnover cover inward supplies also??

I m purchasing milk from doodh sangh and sell to customers.....milk is zero rated supply.....i m purchasing and selling only milk and my turnover is above 1 crore.....shud i file return under gst?......

composition dealer is sales out of state ?

x a dealer in lubricant have closing stock of rs100 as on appointed day, the stock carries excise duty of 14% and stock is fully supported with excisable invoice. my query is whether closing stock @14% will be allowed in GST or Will be limited to the extent of 9% CGST assuming GST rate of 18% in lubricant

Suppose GST Rate for any specific good is 18%(as decided by gst council)

As per GST Act SGST and CGST is applicable to all intra state supply of Goods and Services.

Now i want to know how i should bifurcate SGST and CGST in Invoice?

whether they both should be charged in equal proportion i.e. 9% of CGST and 9% of IGST or there is any other proportion ratio

Please guide me on the same with reference of clause/section/rule of Act.
