Madam,
As per para 2 (II) (a) of Circular No. 1013/1/2016- CX. dated 12.01.2016while filing refund/ rebate claim for the first time, the claimants opting for this facility shall provide one-time authorization in duplicate, duly certified by the beneficiary bank in a prescribed format (enclosed as Annexure-A). One copy shall be retained by the department and one copy shall be sent to the bank with the first refund sanction order of the applicant.
As per para 3 of the above mentioned Circular the facility of e-payment of refunds/ rebate is already operational in certain Central Excise zones such as Mumbai-II, Hyderabad, Chandigarh and Chennai. You can contact central excise assessees in these zones and ascertain from the formalities to be completed by you for availing the facility of e-payment of refunds/ rebate. The Circular directs other Central Excise Zones to contact the above mentioned zones. Therefore you can also follow the same by contacting central excise assessees in Mumbai-II, Hyderabad, Chandigarh and Chennai Zones.
