I recently recieved this intimation 143 from CPC where i have been asked to pay 618rs.
This is what my situation is:
1) I filed my return online through perfios a finance manager portal.while preparing i got a tax payable of 660 rs which i didnt pay while filing return. I paid 660rs as self assesment tax later.
2) Now it was re-calculated as 618 and i got this intimation.
I called customer care CPC and they said u need to have the xml saved during the return which i dont have and i am not sure as i filed through another website(perfios)
