<h1>Automation of indirect tax administration enables centralized e-registration, e-filing, and electronic processing of refunds and disputes.</h1> Automation of Central Excise and Service Tax establishes a centralized web-based system that enables electronic registration, filing and scrutiny of returns, electronic processing of refund claims and permissions, maintenance of assessee running accounts, automated reporting, risk-based audit selection, export processing, and dispute-resolution workflows. The registration regime distinguishes new, existing, non-assessee and LTU clients with email-based TPIN/password procedures and mandatory PAN for certain refunds. Operational controls require permanent usernames, periodic password changes and validated email records; the system provides offline utilities, helpdesk support and specified technical requirements for access.
