We received email from CPC banglore about arrear demand of Rs. 787060 After that we received notice for Demand of Rs.787060 from Income tax Department for A.Y.-2008-09 dated 07/08/2012 & 03/09/2012. We have submitted Rply of all that notices that we have submitted ITR for A.Y. 2008-09 as on 03-10-2008 & submitted tax of Rs. 652880 for A.Y. 2008-09 by challan Dated 23-05-2008. Now the AO says that the amt. we paid as tax is recorded in his records as paid in A.Y. 2009-10 & this is the mistake of bank. When we went to bank bank says that they sent all the challan at the same day the challan received to jaipur & the mistake can now be corrected by ITO. Please advice on the matter.
