September 15 Deadline: What You Need to Know for ITR Filing

The income tax return (ITR) due date for assessment year 2025-26 is set for September 15, 2025. If you’re still waiting for an official extension from the CBDT, here’s the practical info you can act on right now.

Why the Deadline Matters

Missing September 15 means you’ll face a late filing fee of Rs 1,000 to Rs 5,000 plus interest on any tax due. The fee isn’t a flat amount – it climbs the longer you wait. Getting your return in on time saves money and keeps you clear of notices.

Possible Extension Scenarios

In the past, the CBDT pushed the deadline from July 31 to September 15 because of major form changes and system upgrades. If they decide to extend again, they’ll announce it on the income‑tax portal. Until then, treat September 15 as the hard deadline.

Here’s a quick checklist if the deadline slips:

• Watch the official portal for any new notification.
• Keep your documents ready – Form 16, bank statements, investment proofs.
• Use the ‘Belated Return’ option if you file after September 15. You can still submit until December 31, 2025, but the penalty still applies.

How to Avoid Penalties

Start early. Gather all your salary slips, interest certificates and rent receipts by early August. File a draft return on the portal, even if you need to make corrections later. A draft lets you see the tax computation and catch mistakes before the final submission.

Use the pre‑filled ITR form that the portal generates from your PAN. Verify each entry – mismatches trigger notices that can cost you time and money. If you have capital gains or foreign income, double‑check the schedule sections; these are common error spots.

What to Do If You Miss September 15

Don’t panic. Log in to the e‑filing portal, select ‘Belated Return’, and upload the final ITR. Pay the late fee online; the system will calculate the exact amount based on how many days you’re late. After payment, keep the receipt as proof – you’ll need it if the tax department asks.

Remember, interest on any tax due continues to accrue until you clear the amount. Paying the tax liability early, even if the return is late, reduces the interest burden.Finally, set a reminder for next year. Filing before the deadline each year builds a habit and keeps your compliance clean.

Stay on top of the September 15 deadline, watch for any CBDT updates, and follow these steps to keep penalties at bay. With a bit of organization, you’ll breeze through the filing process and avoid unnecessary costs.
