The Income Tax Department on Monday extended the deadlines for corporate income tax returns and tax audit reports by 21 days for assessment year 2026-27. Corporates will now have until November 21 to file their income tax returns, against the earlier October 31 deadline. The deadline for submitting tax audit reports has moved from September 30 to October 21, the Central Board of Direct Taxes (CBDT) said in a statement. The decision follows demands from tax practitioners, who had flagged a compressed audit window after the August 31 deadline for filing returns in non-audit cases.
