Can I file GSTR1 for the month of July 2017, then file GSTR3B for the month of August 2017

Sir

COMPANY PAID EDUCATION EXPENSE OF ONE THE RETIRED EMPLOYEE'S SON. CAN THIS EXPENSE COME UNDER THE HEAD EXGRATIA.

Are the due dates for gstr1 and gstr2 for august month been announced????

I have already filed NIL gstr3B for July. But after filing I discovered that my gstr2a for july is showing some invoices with gst charged on my bank charges and gst on my telephone bill. CAN I still show it in my gstr2 july return and claim this as eligible ITC for adjusting in future months even though i have filed NIL july GSTR3B ??

reverse charge is applicable on which expenses?

My Cilent is having NA Land on his personal name, now he has created partnership firm with friends to develop the same for bungalows scheme. Now at the time of sale of bungalows if they enter into two separate agreement with buyer one for land and and another for construction of building.Now in this case GST on land agreement is not applicable, but in agreement of building what will be the GST rate 12 or 18 ?

Is there any other way for Tax Planning in such situation to minimize GST tax rate ?
