Filing your income tax return on time is necessary because all the welfare schemes and institutions run by the government are fuelled by direct and indirect taxes paid by the general public. The Income Tax Act (1961) under section 139 (1) makes it clear that individuals with an income exceeding the stipulated amount must pay a decided percentage of income tax every year. The last date for filing your income tax is July 31, although the Income Tax Department might allow a grace period ranging between 15 and 30 days to complete the necessary steps. Let us now look at the steps you need to follow for filing your income tax yourself.
