	According to Section 44AB of the Income Tax (IT) Act, 1961, tax audit applies if turnover exceeds the limit of Rs 60 lakh from assessment year (AY) 2011-12 (up to AY 2010-11 it was Rs. 40 lakh). 
	For calculation of turnover for tax audit, the aggregate amount of positive and negative differences arising from dealing in such transactions is the turnover for speculative transactions.
	
	For F&O the above rule should be applied.
	For non-speculative business, i.e., delivery-based transactions, the turnover is calculated as total amount of sales.
