Processing of tax deduction statements: adjustments, interest and fee computed, intimation and refund determined within statutory period. Processing of tax deduction statements requires adjusting statements for arithmetical errors and incorrect claims apparent from the statement, computing interest and any fee, and determining the net sum payable by or refundable to the deductor after adjusting against amounts already paid. An intimation specifying the payable amount or refund must be generated within one year from the end of the financial year of filing, and refunds determined shall be granted. The Board may make schemes for centralised processing and for processing statements filed by non deductors.
