IT section 143(1)

correction 1Lakhs for house loan premium

Also please let me know the procedure to file rectification under 154.

What is Home Loan premium, do you mean the principal or is it principal and interest?, Secondly is the home self occupied by you or let out, for the home loan you are claiming as deduction? Thirdly what is the portion of Principal & interest as per the Bank certificate for the home loan repayment. Further you have claiming 1.5 k as medical reimbursement. Reimbursement upto 15000 is allowed as per IT rules. What are the expenses for which you have claimed 1.5 k(150,000).

principal is around 1.2Lakhs  and the interrest is around 1.8 lakhs.  in my form 16, the principal is truncated at 1 Lakhs ( as per the laws )and the interest to 1.5 L  . it is self occupied.  in my form 16, the medical reimbursement 15K is shown , but it is not there as per the AO

Write a detailed letter to the A.O showing him the ommissions committed while completing the assessment and attach a scanned copy of your Form 16 and the Bank certificate in PDF format along with the letter and mail the same to itdcpc@incometaxindia.gov.in since the intimation was received from CPC, further, I suggest that you file a hard copy of the letter and supporting to the Jurisdictional assessing officer also requesting to rectify the intimation and send a fresh copy of the intimation after the rectification.
