Tax experts advise to avoid mistakes and delay in filing of ITR, individuals should opt for online income tax filing process as, according to them, e-filing helps in correcting mistakes on a real-time basis. Besides, there are a number of online portals that make the process hassle free. According to Vikas Dahiya, CEO, All India ITR, it is important for the taxpayer to choose the correct ITR form based on his or her known sources of income. For example, salaried individuals also having income from property and other sources like interests amounting to a total income of up to Rs 50 lakh can use the one-page ITR 1 or the Sahaj form. The Income Tax Department has already released seven forms, ITR 1 to ITR 7, for different types of taxpayers. This year the IT department has made certain changes in ITR 1 and ITR 2. For example, for FY2018-19, taxpayers having below Rs 5 lakh income cannot be filed ITR 1 in paper format with no refund. Now, only super senior citizens of age 80 years and above can file ITR 1 and ITR 4 in paper format.
