Income tax return last date: Assessees are required to file the ITR for FY2018-19 by August 31

The Income Tax Department has extended the due date for assessees to file their income tax return for financial year 2018-19 (assessment year 2019-20). Now, those originally required to file their income tax returns by July 31 will have to do so by August 31. "The Central Board of Direct Taxes (CBDT) extends the 'due date' for filing of Income Tax Returns from July 31, 2019 to August 31, 2019 in respect of the said categories of taxpayers," the Ministry of Finance said in a statement on July 23. This gives the income tax assessees an extra month to file their income tax return. The Income Tax Department has, on its website (incometaxindia.gov.in), laid out a step-by-step guide for assessees to prepare and submit their income tax return (ITR) online.

In this case, the user can proceed by clicking on the link and downloading the ITR-V form. The ITR-V is also sent to the registered email of the user. Uploading the ITR with the DSC completes the return filing process.

In case the return is not uploaded with the DSC, the ITR-V form should be printed, signed and submitted to the Centralized Processing Centre (CPC) within 120 days from the date of e-filing. The return is processed only upon receipt of a signed ITR-V, according to the taxman.
