Processing of fringe benefits returns: centralised computation, intimation, and assessment powers enforcing adjustments and refunds. Returns for fringe benefits are processed by correcting arithmetical errors and apparent incorrect claims, computing tax and interest on the adjusted value, adjusting for taxes already paid, and issuing an intimation specifying tax payable or refund; the Board may implement a centralised processing scheme. The Assessing Officer may, within prescribed time limits, require production of evidence, hold a hearing and make a written regular assessment of fringe benefit value, with amounts paid or refunded under processing treated as paid towards that regular assessment and any excess refund deemed tax payable.
