wrong pan no.

The Income tax officer may ask the employee to produce form 16 at the time of processing the return and give credit on that basis. This is one of the possibilities. The other possibility is that the ITO may ask the employee to approach the employer to rectify the mistake by revising the return. Most probable action would be first mentioned.

but for f.y. 2007-08 the time for filing revised return have expired.

Then forget about it. For FY 07-08 there won't be any action on quoting wrong PAN as the software of the department itself was not a fullproof one. Thats why they are now introducing Form No 17 to pay taxes online as the PAN will be verified at the time of payment itself. if u dont have pan of deductee u cannot make payment. This will be applicable for tax deducted on or after 1st july.

but wht abt the refund of the employee? he will ask the company why it has quoted wrong pan in returns due to which he has not been able to get his it refund? can he not ask the employer to compensate his loss?

Only human beings can commit mistakes. The employee should approach the ITO & submit a photocopy of his form 16 stating the the fact that the wrong pan has been quoted in the etds returns and hence the credit on OLTS against his pan did not appear. You can help him out by giving the photocopies of challans of deposit of tax with reconciliation of challan amount in an excel sheet. The Assessing officer will consider the facts of the case and dispose it off giving credit to such employee.
