I am a central govt employee.I am residing in a rented house.I have got rs.25404 during the year 2012-13 as HRA.I paid rs.54000@4500/month during the year.The rent receipt signed by house owner,I submitted to my employer.But my employer did not consider and did not deduct from my total salary as a result more tax was deducted as I calculated.Please tell me Is there any new rules for this ?If not, can I file my ITR for refund of tax deducted extra as my calculation?
