Itr hra, medical, lta ay 2014-15

Dear Experts,

My name is Nikhil Nair working with KPIT - Pune.

Due to some family problems I could not submit investment proofs (FY 2013-2014) and file ITR (AY 2014-2015).

So the tax deducted was a lot because I failed to submit investment proofs and file ITR.

I did not get exemptions on HRA, Medical Reimbursement, LTA, LIC, Home Loan Interest + Principal etc.

I have all the proofs for the exemptions.

We have a help desk in our company now for filing ITR and the tax consultant said that I cannot claim exemption on section 10 (HRA, LTA, Medical Reimbursement) for AY 2014-2015.

Is this true? Why is it that if I delay ITR by one year they wont take them? I thought there was a penalty for the same and I would still get returns.

Kindly advice.

Thanks,
Nikhil Nair
