TDS shall be made at the time of payment or credit to the account of the payee whichever is earlier.Since you are reversing the entry you are not required to deduct TDS on monthly provision entries.

why are you doing this. if for MIS or monthly b/s then no need to enter these entries. only ficticious entry can be made. no need to deduct TDS as you are reversing entry next month. But it can create problem in income Tax. because it is difficult to explain them the nature of entries.
