The Income Tax Department on Saturday extended the deadline for individual assessees to file their returns for financial year 2019-20 (assessment year 2020-21) by a month, in a relief to taxpayers on account of COVID-19. Taxpayers now have until December 31 to file their return of income earned between April 1, 2019 and March 31, 2020, instead of November 30. For individuals required to get their accounts audited, a new deadline of January 31 is applicable, instead of December 31.
