A tax return is defined as a form or different types of forms filed with a taxing authority which reports income, expenses, and other pertinent tax information. Tax returns make it simple for taxpayers to calculate their tax liability, schedule tax payments and request refunds for the overpayment of taxes. All taxpayers who are filing their income tax returns are required to determine the type of income tax return (ITR) form they need to fill before actually filing their returns. The form to be filled is solely dependent on the income that the taxpayer earns, or in certain cases if the taxpayer holds assets in a country other than India or earns any form of income from a country other than India.
