Hra exemption

Hello,

I have a query related to HRA exemption.

I get HRA component as my part of salary. But in my organization, I could not submit rent receipts to claim the HRA exemption. So it is not reflected in my FORM 16 received from my company.

Now is it possible to claim HRA as deduction in my final ITR at the time of filing ITR.

Please let me know if it's possible. If yes, then what all docs are required for it?

Thanks,

Sharad
