Under Section 139(1), Explanation 2 of the Income-tax Act, 1961, where the accounts of a partnership firm are required to be audited under the Income-tax Act or any other applicable law, the partners of such firm are also covered under the corresponding audit-category due date for filing their individual income-tax returns, irrespective of whether their individual accounts independently require an audit.
Accordingly, for AY 2026–27, the original due date of 31 October 2026 has been extended by CBDT to **21 November 2026**.
However, where the partnership firm is not subject to audit, the applicable due date for its partners having business or professional income is generally 31 August 2026, subject to the applicability of other specific provisions.
Therefore, the determining factor is the audit status of the partnership firm and the applicability of Section 92E, rather than whether the individual partner independently qualifies for a tax audit.
