VAT return filing arrangements centralise receipt and prioritise refund claims to ensure prompt data entry and tracking. Centralised arrangements require designated Front Office counters and extension counters to accept and segregate monthly and quarterly VAT returns, with priority processing for quarterly returns claiming refunds. A colour-coded acknowledgement procedure (pink for refund; green for no-refund) with stamped, serialised portions ensures TIN entry and tracking. All returns must be manually received, bundled, indexed and data-entered at the Front Office; zonal in-charges are accountable for staffing, transport, supervision and forwarding to wards. Returns with incorrect TIN or technical faults are to be sent to the concerned ward for corrective action.
