c form

Hi,

I have a query which i hope u can answer. the query is:

During the second quarter of 2008-9 i.e. during the period of 1/7/2008 to 30/9/2009, a machine was purchased from outside Delhi but due to inadvertence, the same was shown as local purchase and 1/3rd 

VAT claim was accordinly calimed in VAT return.

NOW

During the second quarter return of 2009-2010 i.e. 1/7/9 to 30/9/9, again the 1/3rd VAT on same was claimed.

HOWEVER in Mach, 2010, the said mistake has been detected.

MY QUERY NOW IS:

1.  The selling interstate dealer is now asking for C--Form towards the purchase of machinery by me . Can  I apply for issuance of C-Form with VAT Officer?

2.   In case i am not eligible for getting the C-form 

, how much tax and interest I have to pay. the value of machinery was Rs. 8000000/- and tax was paid at the time of purchase @ 2% in the hope that C-form will be issued?

3.   Shall I file revised return for 2nd quarter of 2008-9 rectifying the mistake of claiming 1/3 input VAT? If yes, what will be the tax implications?

With Warm Regards,
