It is mandatory by law that a citizen of India is obliged to file returns to the income tax department at the end of every financial year before the due date arrives. If the citizen misses the due date, then they would have to pay a penalty. The Income Tax Act, of 1961 and Income Tax rules, of 1962 have solidified this in the Indian constitution. Income tax online filing is also becoming quite popular due to its ease of access and convenience.
