Here are key things to know about belated income tax return (ITR):

1.

2. A belated return attracts late filing fees under section 234F of the Income Tax Act.

What are the income tax exemption limits for an individual?

There are three categories of individual taxpayers- individuals (below the age of 60 years) which includes residents as well as non-residents, resident senior citizens (60 years and above but below 80 years of age) and resident super senior citizens (above 80 years of age). Individuals having an annual income of up to Rs 2.5 lakh are not required to file income tax returns. For senior citizens (individuals between 60 years and 80 years of age), the limit is Rs 3 lakh, and for very senior citizens (aged above 80 years), the limit is Rs. 5 lakh, according to the taxman.
