I have made some trick of my own....like 16 yr me contract kiya and profit not credited to p&L account...19 yr me scientific research kiya...21 yr me exp disallow ho gye and 23 year me specified party ko payment kiya...thirty me hundi (focus on tune for it ) 32 me unabsorbed dep and c/f of losses (as section 32 dep ka hai income tax me) 33 tum dono twins ho to tumhe deduction milega...36 me divd distribution tax (chattis ka aankada kehte h na to soch lo ki Co. Ka 36 ka aankada h IT walo se for ddt) and baki sb i think yad ho jayenge easily...agr nahi hote to aisa hi kuch technique use kar skte ho if u like it...
