One of my friend's net taxable income in india for financial year ending in march 06 was less than 1,00,000 as he joined service in November 05. So no tax was deducted from his salary. But he has not filed his returns. Will he be fined for this???

currently he is ion zurich.And another problem is how do he file returns from there???
