Rent Receipts

Hi all

Just wanted to inquire. I have a case come up to me. In that the client had claimed HRA deduction. He had a house in delhi and had shown that he paid rent in Gurgaon. So he got a deducton of HRA, Housing loan repayment and interest paid deduction. Now the problem is that his case is in scrutiny and rest everything is perfect except that his rent receipts were false.

So what should be done????

To what extent does the income tax officer generally enquires.

Please advise.

Thanks
