Filing Tax Returns For Previous Years

Question: IT returns of previous years?

hai,
It so happened that my friend worked in a small company before he left India in April. That year being first to for him with taxes, he did not file any return as he had already left. His PAN arrived after he left India. He have not been filing taxes since then as he is outside India. Is it possible to file previous year returns this late? Is there any penalty for that?
Thought will clarify more on this. It seems that the taxes have been paid for the year he worked with the help of a professional consultant by the company for all its employees. But he has not been filing returns for the year since he left. He left for higher studies and there is no income from his previous company nor is he working abroad. So does he still have to file the returns. The questio arose because, he has a PAN number and if so is it compulsory to file returns every year irrespective of income status.

Answer: If your friends income is less than taxable, he can forget filing. Or he may thing about it when he returns to India.
