Thks for Replying Raman....
I read somewere that NSDL was appointed by the GOV. to function til 31st Oct. 2012 and it worked very efficiently till that time.... but after that ITD has appointed TCS for the same or has not renewed the contract of NSDL ...this is wat is causing the delay....
New returns are accepted well and fine its only the correction statements that are delayed....
may be the coz is that the old return lies with NSDL nd the revised return is filed with TCS which is still wanting the old original data that is still with nsdl...
