Penalty for missing ITR filing last date: Who has to pay and who doesn't

Penalty for belated ITR filing: Under the Income-tax Act, 1961, a penalty or a late filing fee is levied when a taxpayer misses the last date to file income tax return. The late filing fee must be paid or else final submission of income tax return form cannot happen. However, not all taxpayers are required to pay penalty for filing belated ITR.
