Any bad debt write allowance come with a trigger.
By the tax case reported at (2017) 54ITR (Trib) (SN) 8 it is by far important that any bad debt write off claim must match the balance shown as payable by the party in its books of account. In the absence of any reconciliation it is likely that unexplained difference may get disallowed during assessment.
In this case the amounts claimed as write off in assessee books exceeded those shown in the respective party books .
