Dear Expert


This year there was refund of 40,000 from income tax department.  But  today I received 154 notice from IT that there was  outstanding demand from  100900 in AY 2010-11 and they will adjust refund w.r.t. outstanding demand .  I am salary person and all TDS was detected from my salary. ITR and Form 26AS matches for A.Y 2010-11.  So far I have not received any demand  for A.Y. 10-11  I filed  ITR manually in AY 2010-11  I am not sure how can demand will be Rs. 100900.
Can some one guide me how should I proceed future.  I am sure there is some mistake some where . since i dont have any letter i can not guess what went wrong. I am now not leaving for CITY where I filed return 2010-11.  Please help and guide me.
