From 1.9.2014 to 28.2.2015 Time limit for availing (taking) credit was 6 months.
From 1.3.2015 onward Time limit increased to one year vide Notification No.6/2015-CE(NT) dated 1.3.2015
In terms of Rule 4(7) of Cenvat Credit Rules,2004 (as amended) , input service credit shall not be allowed by the department and also no hope of getting the relief through litigation.
Earlier also time limit of taking credit within 6 months was enforced vide Notification No.28/1995-CE (NT) dated 29.6.1995. The Supreme Court upheld such amendment of restriction of taking Cenvat Credit within 6 months in the case of Osram Surya Pvt. Ltd. Vs.CCE Indore reported as 2002 (142) E.L.T. 5 (S.C.).= 2002 (5) TMI 49 - SUPREME COURT OF INDIA The Apex observed as under:-
Modvat - Duty paying documents - Availment of credit within six months of the issue of duty paying documents - Amendment to Rule 57G of the Central Excise Rules, 1944 introduced by Notification No. 28/95-C.E. (N.T.) providing such time limit of six months is prospective in nature - Amendment does not take away any vested right but merely introduces limitations for availment of credit - Amendment is not retrospective in operation since it does not cancel the credit nor does it effect the right of the persons who have already taken credit - In the absence of challenge to the validity of the Rules, the pleas that time limit cannot be applied to credit accrued prior to the amendment and introduction of amendment to rule is arbitrary, not available. [1999 (106) E.L.T. 3 (S.C.)= 1999 (1) TMI 34 - SUPREME COURT OF INDIA (EICHER MOTORS LTD. Versus UNION OF INDIA) distinguished]. [paras 7, 8, 9]
Interpretation of statute - Change in law - Amendment to Rules incorporating time limit for availment of credit - Introduction of time limit does not take away any vested right, it is only the time limit within which said right is to be enforced hence amendment is prospective in effect - Erstwhile Rule 57G of the Central Excise Rules, 1944. [para 7]
Penalty imposed specifically questioned before the Tribunal but it failed to consider - Penalty imposed on similarly placed assessee, however, set aside by the Tribunal - Modvat credit whether can be availed beyond a period of 6 months from the date of issue of duty paying documents issued prior to amendment of Rule 57G of Central Excise Rules, 1944 - Penalty set aside by the Supreme Court - Rule 173Q ibid. [para 10].
Go through the judgement word for word and read between the lines and then decide whether to challenge the validity of restriction of time limit of one year or not. Without challenging the amendment, relief is not feasible. Now it is your option whether to challenge validity of rule of one year limit or not.
As per the present law, you cannot take credit for the past period which is more than one year.
