Filing of Final Return GSTR-10

on 1st Sept 2019 we have Applied for cancellation of GST registration and on 04th Sept 2019 got cancellation order from authority and the taxpayable mentioned in the order is Zero . But here we have 23000/- input tax credit in GSTR-2A. We have not utilised this ITC at the time of filing of GSTR-3B. Because we have filled"NIL" returns only.

Now Can we file final return as "NIL Return" or Do we need to reverse this ITC.

One more problem facing in final return that we can reverse the input tax credit on Goods and there is no option for Services. We have received the above mentioned ITC from Services.

please suggest us.
