Ratification of wrong remittances: procedure permits transfer of misapplied tax payments after representation, verification, and PAO action. Procedure for rectifying payments made to incorrect accounting heads or registration numbers: assessees must represent to the Commissioner with certified remittance challans, returns and supporting documents; obtain no-objection certificates and Range Officer certifications where payments are credited to another registration; produce both Central Excise and Service Tax challans when major heads are incorrect; and provide centralized registration and surrender certificates when relevant. Field formations must verify returns, payment authenticity, and incorporate corrected challan details before forwarding corrected ledger entries to the appropriate e-PAO for transfer, with major-head disputes referred to the Principal Chief Controller of Accounts.
