ITR filing due dates under modified Income Tax Bill 2025: What every taxpayer should know

The Income Tax (No. 2) Bill 2025 has defined the due dates for filing Income Tax Returns (ITR). So, what’s new? Have the deadlines changed? The answer depends on the type of taxpayer.

The ITR filing due dates under the new Income Tax Bill vary based on the type of assessee and their audit requirements.

For most salaried individuals and other taxpayers not subject to audit, the deadline remains July 31. However, those requiring audits, including companies, firms, and their partners, must file by October 31.
