ITR Filing Last-Minute Guide: What to Do Before the Deadline

Running late on your income tax return? Here is a practical step-by-step checklist to file ITR correctly, verify AIS data, and avoid penalties before the due date.

Still haven't filed your ITR?

If the income tax return deadline is approaching and you have not started yet, do not panic — but act today. Filing late can lead to a fee under Section 234F, loss of certain deductions, and delayed refunds.

Step 1: Log in and download AIS & Form 26AS

Before entering any figure, open the AIS (Annual Information Statement) and Form 26AS on the Income Tax e-filing portal. Match salary, interest, TDS, and capital gains with your own records. Discrepancies are a common reason for notices later.

Step 2: Pick the correct ITR form

Choosing the wrong form can invalidate your return. When unsure, get it reviewed by a tax expert before upload.

Step 3: Keep these documents on your desk

Step 4: File, then e-verify the same day

Uploading the return is not enough — you must e-verify within 30 days (Aadhaar OTP, net banking, or DSC). An unverified return is treated as invalid.

When to get professional help
