Hra exemption with two rent agreement

An employee can submit 2 rent agreements if he has changed the house on rent.......

One question

when first agreement is till 28-2-15 then why rent was increase with revised agreement 01-8-14.

ITO will definetly catch the point that this is only to save tax on increased HRA.

for your question two rent agreement can be given but both dates must not be clashed. in your example dates are clashed so it is not practical
