Proprietorship firms are required to file income tax return like LLPs and Companies registered in India. Since proprietorship firms are considered to be one and same as the proprietor, the income tax return filing of the proprietorship firm is the same that of the proprietor. Under Income Tax Act, all proprietors below the age of 60 years are required to file income tax return if total income exceeds Rs. 2.5 lakhs. In the case of proprietors over the age of 60 years but below 80 years, income tax filing is mandatory if total income exceeds Rs.3 lakhs.
