Plz help- idt amendment query

I have a question- amendments upto 30/4/16 are applicable for nov 16. But what about amendment effective from 1/4/16 will be applicable for AY 16-17

Eg. Service tax returns will be filed on 30th nov wef 1/4/16

So for AY 16-17 what will be applicable half yrly returns or a yrly return? Since amendment applicable till 30/4/16 applies but AY 16-17 is applicable for nov 16 exams.

Please help
