Sir,
Explanation (B) of Section 11 B of Central Excise Act, 1944 defines "relevant date' as
"relevant date" means,-
(a) in the case of goods exported out of India where a refund of excise duty paid is available in respect of the goods themselves or, as the case may be, the excisable materials used in the manufacture of such goods,-
(i) if the goods are exported by sea or air, the date on which the ship or the aircraft in which such goods are loaded, leaves India, or
(ii) if the goods are exported by land, the date on which such goods pass the frontier, or
(iii) if the goods are exported by post, the date of despatch of goods by the Post Office concerned to a place outside India;
(b) in the case of goods returned for being remade, refined, reconditioned, or subjected to any other similar process, in any factory, the date of entry into the factory for the purposes aforesaid;
(c) in the case of goods to which banderols are required to be affixed if removed for home consumption but not so required when exported outside India, if returned to a factory after having been removed from such factory for export out of India, the date of entry into the factory;
(d) in a case where a manufacturer is required to pay a sum, for a certain period, on the basis of the rate fixed by the Central Government by notification in the Official Gazette in full discharge of his liability for the duty leviable on his production of certain goods, if after the manufacturer has made the payment on the basis of such rate for any period but before the expiry of that period such rate is reduced, the date of such reduction;
(e) in the case of a person, other than the manufacturer, the date of purchase of the goods by such person;
(ea) in the case of goods which are exempt from payment of duty by a special order issued under sub-section (2) of section 5A, the date of issue of such order;
(eb) in case where duty of excise is paid provisionally under this Act or the rules made thereunder, the date of adjustment of duty after the final assessment thereof;
1[(ec) in case where the duty becomes refundable as a consequence of judgment, decree, order or direction of appellate authority, Appellate Tribunal or any court, the date of such judgment, decree, order or direction ;]
(f) in any other case, the date of payment of duty.
It is nowhere stated under the above provision that relevant date for calculating the period of one year is from date filing of prescribed return.
It is only under Explanation 1 (b) (1) of Section 11A of Central Excise Act it is provided that relevant date for demanding duty of excise has not been levied or paid or has been short-levied or short-paid, and no periodical return as required by the provisions of this Act has been filed, the last date on which such return is required to be filed under this Act and the rules made thereunder.
Therefore for refund of excise duty /paid /service tax paid the refund claim is to be filed within one year from date of payment of duty/tax.
