As the income tax filing season gathers momentum, taxpayers must keep a close watch on several important statutory deadlines throughout the financial year. Whether you are a salaried employee, self-employed professional, business owner, or tax deductor, meeting these due dates is essential to remain compliant with the Income Tax Act, 2025.
Failure to comply with prescribed timelines can result in interest, late filing fees, and unnecessary tax disputes. Planning your tax obligations well in advance can help you avoid last-minute complications and ensure seamless compliance.
Taxpayers whose estimated tax liability requires payment of advance tax must ensure timely payment in four instalments during the financial year.
Advance Tax Schedule
Missing or delaying any instalment may attract interest under the Income Tax Act, 2025.
Interest may be levied when the total advance tax paid is less than 90% of the assessed tax. The interest is calculated at 1% per month or part of a month on the outstanding amount until the liability is discharged.
Where taxpayers fail to pay the prescribed instalments or pay a lower amount than required on each due date, interest for deferment of advance tax may also become applicable at 1% per month for the prescribed period.
These provisions broadly correspond to Sections 234B and 234C of the Income-tax Act, 1961.
For most salaried individuals, pensioners, and other taxpayers who are not required to get their accounts audited, the due date for filing the Income Tax Return (ITR) for Assessment Year 2026-27 is 31 July 2026.
Filing the return before the due date offers several benefits, including:
Missing this deadline may lead to additional compliance costs and restrictions under the Act.
Certain taxpayers having business or professional income and filing ITR-3 or ITR-4, who are not subject to tax audit, may have a filing due date of 31 August 2026.

Taxpayers whose accounts are required to be audited under the Income Tax Act should complete the audit process well before the filing deadline.

Before filing the return, taxpayers should reconcile:
Proper reconciliation helps minimize notices and processing delays.
If a taxpayer misses the original due date for filing the Income Tax Return, a Belated Return may generally be filed up to 31 December 2026, subject to the provisions of the Income Tax Act, 2025.

A significant relief under the Income Tax Act, 2025 is the extension of the time limit for filing a Revised Return.
For Assessment Year 2026-27, taxpayers may revise an already filed return up to 31 March 2027, which marks the end of the relevant assessment year.
This extended timeline enables taxpayers to:
However, taxpayers should avoid unnecessary delays and revise the return promptly after identifying any mistakes.
Income tax compliance is not limited to filing the Income Tax Return alone. Taxpayers should monitor the entire compliance calendar, including advance tax payments, audit reporting, and return filing deadlines.
Maintaining proper books of account, reconciling tax records in advance, and filing returns within the prescribed timelines can significantly reduce compliance risks while avoiding interest, penalties, and unnecessary litigation.
A proactive approach towards these important dates will ensure smooth tax compliance throughout Assessment Year 2026-27.
