The CAT 2026 form correction window lets registered candidates edit their photograph, signature, and test city preference on iimcat.ac.in after the CAT registration deadline closes on September 15, 2026.
CAT 2026 correction form window is expected to open around late September to early October 2026, open for 3-4 days, ahead of the exam on Sunday, November 29, 2026. No fee is charged for corrections, and fields like name, date of birth, email, and mobile number cannot be edited.

What Is the CAT 2026 Form Correction Window?
The correction window is a limited-duration facility on iimcat.ac.in that opens only after registration closes. It exists because CAT receives lakhs of applications in a short window, and a percentage of candidates inevitably upload the wrong photo, misspell a test city preference, or submit a signature that doesn’t meet specifications.
Why IIMs Open a Correction Window
Once the admit card generation process begins, no further changes are possible. The correction window is IIM’s built-in buffer to reduce last-minute helpdesk chaos and ensure candidates aren’t penalised for a fixable, minor error.
Who Should Use CAT 2026 Form Correction Window
Not every candidate needs to log back in. If your form was accurate at submission, you can skip this step entirely. It’s meant specifically for candidates who spot an error in their photograph, signature, or city preference after payment.

What Can You Edit in the CAT 2026 Correction Window?
This is the part candidates get wrong most often: the correction window is not a full form re-edit. It’s a narrow, specific fix.
| Editable Fields | Not Editable |
| Photograph | Full Name |
| Signature | Date of Birth |
| Test City Preference (order/choice) | Mobile Number |
| — | Email ID |
| — | State / Category |
| — | Work Experience |
If you’ve made an error in a locked field like your name or category, the correction window won’t help; you’ll need to contact the CAT helpdesk directly and follow their specific escalation process, since these fields carry legal and eligibility weight.
How to Correct Your CAT 2026 Application Form – Step by Step
- Visit iimcat.ac.in and log in using your registered User ID and password.
- Open your submitted application and review each section carefully.
- Locate the correction/edit link, active only during the correction window.
- Re-upload your photograph or signature if either doesn’t meet specifications, or update your test city preference order.
- Accept the declaration checkbox and submit the corrected form.
- Download or print the updated application for your records.
Keep a fresh photograph and a clean signature scan ready in advance, don’t wait for the window to open before sourcing these files, since it stays live for only a few days.
Common Mistakes to Avoid During the Correction Window
- Ignoring photo/signature specifications: A photo older than 6 months, one with sunglasses, or a signature in capital letters will be rejected even during correction.
- Waiting until the last day: With traffic spiking as the deadline nears, the portal can slow down significantly.
- Assuming everything is editable: Attempting to “fix” your name, category, or work experience here wastes time, these fields are locked.
- Not saving a confirmation copy: Always download the updated form after submitting.

What Happens After the Correction Window Closes?
Once the correction window shuts, no further edits are allowed under any circumstances. The information as it stands becomes final for your CAT 2026 admit card, and eventually for shortlisting at IIMs and other CAT-accepting institutes. Admit cards are expected to be released in early-to-mid November 2026, giving you roughly two to three weeks before exam day on November 29.
