Mvat input tax criteria

Dear All,

Suppose for July to Sep 14 My INPUT TAX ( local purchase ) is Rs. 6 lacs whereas OUTPUT TAX ( local sales +CST sales ) is  Rs.5 lacs ( 4 lac local + 1 lac CST ) ,

Hence , my query is while claiming INPUT , am i allowed to adjust the CST OUTPUT TAX of Rs.1lac against my INPUT .......? 

i.e. my INPUT c/f for JULY to SEP 14 will be Rs.2 lacs ( excluding CST TAX ) or Rs. 1 lacs ( Including CST TAX ) ??

Please suggest

Regards
