<h1>EASIEST System Streamlines Central Excise and Service Tax Payments with PAN-Based Registration and Assessee Codes.</h1> The Electronic Accounting System in Excise and Service Tax (EASIEST) facilitates the payment of Central Excise duties and Service Taxes. Assessee codes, a 15-character identification number, are mandatory for transactions and are based on the PAN number. Location codes specify jurisdictional divisions. PAN-based registration is essential for e-payments, and banks must ensure the validity of assessee codes. EASIEST simplifies the payment process by requiring only one GAR-7 challan copy. Errors in assessee codes or payment details necessitate contacting banks or jurisdictional officers for resolution. E-filing and e-payment options are available, with specific procedures for non-assessees.
