AS per the IT act, small contractors i.e turnover bellow 40 Lakhs, can pay the tax on profit of 8% on turnover.  Moreover, if he choose that option, he need not be mantain any books of accounts.

If that contractor is partner ship firm, less than 40 lakhs T.O, he is [b]not maintaining any books as he chooses the presumptive tax option, how can he arrive the fringe benfit to employees?  on those situations, whether he should be pay the FBT / Not?
