Payment of pre-GST taxes(Central Excise & service tax) is revised by the Commissioner of Indirect Tax & Customs through a circular. The portal for making payments has also been changed. The website migrated from ACES to CBIC-GST portal post the implementation of GST law. Due to this change, the payment of arrear taxes of central excise and service tax will now undergo change. The challan will be created on CBIC-GST portal and the payment will be made on the ICEGATE portal. The change will be effective from 1 July 2019.
