TDS and TCS statement processing requires error adjustments, refund determination, and timely intimation under centralised procedures. Processing of statements of tax deducted at source or tax collected at source, including correction statements, requires adjustment for arithmetical errors and incorrect claims apparent from the statement. Interest and fee are computed on the reflected amounts, and the amount payable or refund due to the deductor or collector is determined after set-off of amounts already paid. An intimation stating the payable or refundable amount must be sent within one year from the end of the tax year, and refunds determined under the process must be granted. The Board may frame a scheme for centralised processing.
