When Income Tax Return Filing is Mandatory Even if Income is Below Exemption Limit
Legal Basis
Section 139(1) of the Income Tax Act, 1961 lays down the requirement for furnishing the return of income. While ordinarily individuals are not required to file returns if their income is below the basic exemption limit, the following specific scenarios override that exemption.
Situations Where Filing ITR is Mandatory (Even Below Basic Exemption Limit):
Sr. No. | Condition (Even if Income is Below ₹2.5L / ₹3L / ₹5L) |
1 | Deposit of ₹1 crore or more in current account during the year |
2 | Expenditure of ₹2 lakh or more on foreign travel |
3 | Expenditure of ₹1 lakh or more on electricity consumption |
4 | If TDS/TCS of ₹25,000 or more has been deducted (₹50,000 for senior citizens) |
5 | If total business turnover/gross receipts exceed ₹60 lakh |
6 | If gross receipts from profession exceed ₹10 lakh |
7 | If the individual is a beneficial owner/signatory in a foreign account or foreign entity |
8 | If claiming refund of TDS, even with nil taxable income |
9 | If filing is required for carrying forward losses (capital loss, business loss, etc.) |
10 | If income is taxable under section 11 (Trust/Institution) or other specific conditions |
11 | If income is claimed as exempt (like agriculture income), but gross income exceeds exemption limit before such exemption |
