Filing income tax is every citizen’s responsibility. The IT department verifies these declarations of income and if any amount has been paid in excess, the department refunds the amount to the assessee’s bank account. All entities are required to file the taxes on time to avoid penalty. The form that contains information of income and tax paid of an assessee is called Income Tax Return. The Income Tax Department of India has various forms for it such as ITR 1, ITR 2, ITR 3, ITR 4S, ITR 5, ITR 6 and ITR 7.
