ITR Filing 2025: Does Extended Deadline Of September 15 Also Cover Advance Tax? | Tax News

Last Updated:June 25, 2025, 15:40 IST

The income tax department has extended the ITR filing deadline for AY 2025-26 to September 15, 2025. This extension does not apply to advance tax deadlines, which remain unchanged.

ITR Filing 2025: The income tax department has extended the last date to file Income Tax Returns (ITR) for the assessment year 2025-26 from July 31 to September 15, 2025, for individuals and taxpayers not requiring a tax audit. This extension offers much-needed relief to crores of salaried taxpayers, pensioners, and small businesses.

But, as the filing deadline is pushed ahead, does this extension apply to advance tax as well? And what about interest penalties under Sections 234A, 234B, and 234C? Here’s all you need to know.

What Has Been Extended?

The ITR filing deadline for AY 2025-26 is now September 15, 2025, instead of the earlier July 31.

This applies to individual taxpayers not subject to audit (i.e., salaried employees, pensioners, freelancers, etc.).

It also applies to those filing self-assessment tax — provided they pay it before the extended deadline.

Does the Extension Apply to Advance Tax Too?

No. The advance tax schedule remains unchanged.

Advance tax payments are governed by Sections 208 to 219 of the Income Tax Act and are due on a quarterly basis, as follows:

The September 15 deadline for filing ITR does not affect the advance tax deadlines. If you fail to pay advance tax on time, interest under Section 234B and 234C will be levied as usual.

“The ITR extension does not shift the advance tax calendar. Interest under Sections 234B and 234C will still apply if advance tax is short or delayed,” said a a Delhi-based chartered accountant.

If you’re a salaried individual and your tax is fully deducted at source (TDS), you usually don’t need to pay advance tax unless you have other income (like rent, capital gains, F&O trading, or interest) exceeding Rs 10,000 in tax liability.

What About Self-Assessment Tax?

If you owe tax while filing your ITR (after adjusting TDS and advance tax), that is considered self-assessment tax. For non-audit cases:

If you pay self-assessment tax and file ITR by September 30, interest under Section 234A (for late filing) will not apply.

However, Sections 234B and 234C (related to advance tax defaults) may still apply.

Extra Refund Interest for Taxpayers

There’s good news for those expecting refunds. With the filing date pushed to September 30, taxpayers may receive more interest on refunds under Section 244A.

According to estimates, this could lead to up to 33% more refund interest, especially for early TDS credit claimants and those whose refunds are substantial.

Checklist for Taxpayers

• Pay advance tax installments on or before their original due dates
• Pay self-assessment tax by September 30 to avoid 234A interest
• File ITR by September 30, 2025 to avoid late-filing penalties
• Keep Form 26AS and AIS updated before filing
• Reconcile TDS credits and bank interest in Form 16/Form 16A

While the extension of the ITR filing deadline to September 15 is a welcome breather, taxpayers must not confuse it with other compliance deadlines. Advance tax dues remain unchanged, and failing to pay them on time will attract interest as usual.
