Centralized processing of withholding statements enables automated determination and intimation of amounts payable or refundable.
Centralized processing creates an automated, unified mechanism for TDS and TCS statements, including correction statements, requiring rectification of arithmetical errors and apparent incorrect claims, computation of interest and fees on adjusted amounts, adjustment against prior payments, issuance of an intimation within one year from the end of the tax year, and grant of refunds; the Board may establish a centralized processing scheme and must address interpretive gaps such as the undefined scope of "incorrect claim apparent" and the tax year/financial year distinction.

Centralised TDS/TCS processing: automated, time bound framework mandates intimation within a year and covers correction statements.
Clause 399 creates an automated framework for processing TDS and TCS statements, including correction statements, requiring rectification of arithmetical errors and adjustment of apparent incorrect claims, computation of interest and fee, determination of net payable or refundable amounts after adjusting prior payments, issuance of a formal intimation to the deductor/collector, and grant of any refund due; it also mandates that intimations be sent within a year from the end of the tax year and empowers the Board to make a centralised processing scheme.
