Service Tax reconciliation: computerised challan matching required to ensure correct headwise accounting and verification. Computerised reconciliation of Service Tax receipts under Major Head 044 requires duplicate TR-6 challans to be entered sub-heading wise at divisional computer cells, transmitted to Headquarters for compilation into 044 statements, and verified by Range Officers. Payments must be made and recorded using the prescribed Major/Minor/Sub-head accounting codes and Sl. Code so amounts are posted to the correct head of account; assessees must complete challans with required identifiers and verifying officers must certify and return verified statements to the designated accounts authority.
