The Central Board of Direct Taxes (CBDT) has said a major compliance change is mandatory disclosure of bank balances under the revised income tax return forms for taxpayers filing ITR-4 for Assessment Year (AY) 2026-27. The government has been gradually increasing the disclosure requirements in ITR forms to bring in more transparency and to have a more data-driven tax administration. CBDT has issued Notification No. 45/2026/F. No. 370142/5/2026-TPL dated March 30, 2026 to provide additional reporting of bank balance in ITR-4 AY 2026–2027. Earlier, the bank account details such as account number, IFSC code and bank name were to be disclosed by taxpayers filing ITR-4, but the disclosure of actual bank balances was optional.
