My rent is 9000/-.I submitted rent receipts  of 6500/-to my company as a part of document submissions for IT Exemptions.upon receeiving my payslip i found out that this slab was the least possible for exempt(Rent-10%).So a sum was taxable and tax was deducted. I still did not not received form16.Can i go ahead changing the rent receipts (Rent receipts have already been provided. I mean to say Revised rent receipts) so as to get my tax back from the company or through ITR.If so how should i proceed with the changes.
