The last date for filing income tax returns (ITR) is July 31, 2019. Unlike previous years, this time the income tax (IT) department may not extend the deadline as strict compliance rules are in force. For taxpayers, this is the right time to sit up and start putting in place documents required in filing ITR. Before starting the tax filing process, a big chunk of taxpayers waits till they get Form 16 and then start collecting requisite documents that play key role in the return filing. This leads to delay in filing ITR.
