Every person who earns income chargeable to tax should file its income tax return with the Income-tax Department before the due date and pay the taxes as applicable for the financial year. If any person fails to do so, such person shall be liable to pay interest as imposed by the Income Tax Act. Under the Income Tax Act, interest is imposed under three subsections of Section 234, viz., 234A, 234B, and 234C.
Every time a person files an Income Tax Return, an acknowledgement is generated. This acknowledgement is known as ITR-V. This means Income Tax Return Verification Form. Once the return is filed, it has to be verified either through Adhaar Based OTP or through net banking.
