CAT 2026 Form Correction: Window Closed on Oct 6, Editable Fields and How to Make Changes

The CAT 2026 Form Correction Window was open from October 5 to October 6, 2026, allowing students to fix specific errors in their submitted application. Conducted by IIM Indore, the Common Admission Test (CAT) 2026 is scheduled for November 29, 2026. The correction window has now closed; students who missed it cannot make further changes to their application through the portal.

IIM Indore permitted edits to photograph, signature, and test city preferences only during the window. Critical fields such as name, date of birth, category, and registered email ID were permanently locked. No correction fee was charged — eligible changes were free during the active window.

What is CAT Correction Window 2026?

The CAT Correction Window is a short, one-time facility provided by the conducting IIM that lets students fix specific errors in their submitted CAT application. It is announced after the registration deadline closes and typically stays open for 24–48 hours only. The CAT 2026 correction window was provided by IIM Indore and ran from October 5 to October 6, 2026.

The correction window exists to address genuine upload mistakes — such as a blurry photograph, an incorrectly scanned signature, or a test city entered in error. It is not a channel for changing identity-critical or reservation-related data. Fields such as name, date of birth, and category are verified against official documents at IIM interview stages; IIM policy permanently locks these at form submission to prevent misuse.

The correction window is your only opportunity to fix errors — no changes are possible after it closes. IIM Indore does not offer a second correction window, and the CAT 2026 window has now closed as of October 6, 2026.

How to Edit the CAT Application Form?

During the correction window, students could log in to the CAT 2026 portal at iimcat.ac.in and follow the steps below to make permitted changes. Although the window is now closed, the process is documented here as a reference for future CAT cycles.

1. Visit the official CAT website at iimcat.ac.in.
2. Click on the "CAT 2026 Login" or "Edit Application" link displayed on the homepage during the correction window.
3. Enter your registered email ID and password to log in to your account.
4. Navigate to the "Application Form" section and click "Edit Form" or "Application Correction".
5. Make the required changes — update your photograph, signature, or test city preferences as needed.
6. Review every change carefully before submitting — the portal may not allow re-editing after submission.
7. Click "Save and Submit" to confirm your corrections.
8. Download and save the updated application confirmation page for your records — you may need it at the exam centre.

Always log out after submitting changes and keep a screenshot or PDF of the corrected form.

Fields You Can Change

IIM Indore permitted the following edits during the CAT 2026 correction window:

Fields You Cannot Change

Name, date of birth, and application number cannot be changed under any circumstances. The following fields were locked from the moment registration was submitted:

CAT Form Correction 2026: Fee

IIM Indore did not charge any additional fee for changes made during the CAT 2026 correction window. Students could update photograph, signature, and test city preferences at no extra cost. This is consistent with IIM’s practice across several recent CAT cycles — the correction facility is provided as a goodwill measure at no charge.

Pay the correction fee within the window — unpaid corrections will not be saved. Since CAT 2026 carried no correction fee, students needed only to click "Save and Submit" after making changes — no payment step was required. Had a fee applied, any unsaved or unpaid correction would have been discarded automatically when the window closed.

For context, the one-time CAT 2026 application fee paid at the time of registration was:

CAT Correction Window 2026: Errors & Problems

Students sometimes encounter technical or procedural issues on the CAT correction portal. The table below covers the most common problems and their solutions — useful during future CAT correction windows:

CAT Helpdesk

Students facing issues with their CAT 2026 application form, correction portal access, or admit card can reach the official helpdesk through the channels below. For CAT 2026, the helpdesk is operated by IIM Indore — the conducting body. Always keep your application number and registered email ID ready before contacting the helpdesk.

The helpdesk does not process corrections on behalf of students — it provides guidance on portal access and technical issues. Form changes can only be made by the student through the correction portal during the active window. IIM does not dispatch admit cards by post or email; all students must download their own admit card from iimcat.ac.in.

CAT Form Correction 2026: Important Tips

1. Act on the first day the window opens. The CAT correction window is typically open for only 24–48 hours. Waiting until the final hours risks losing access if the portal experiences high traffic or downtime near the deadline.
2. Check photo and signature specifications before uploading. The photograph must be recent, passport-size (30 mm × 45 mm), with a white background and no cap or spectacles — file below 80 KB in JPG format. A photo that fails these checks will be rejected and must be re-uploaded before the window closes.
3. Think carefully before changing test city preferences. Opting for an uncommon city may seem strategic, but IIM Indore allocates centres based on availability — your first preference is not guaranteed. Choose cities that are genuinely accessible to you.
4. Save a copy of the corrected application immediately after submission. Download the updated confirmation page as a PDF and store it. The exam centre may ask for it alongside your admit card.
5. Use a desktop or laptop with a stable internet connection. Uploading files on a mobile browser over cellular data increases the risk of incomplete submissions. A wired or stable Wi-Fi connection on a computer is far more reliable for file uploads.
6. Edit only what genuinely needs to be corrected. Changing test city preferences without a good reason may result in an inconvenient centre. Do not modify fields unless there is an actual error to fix.
7. Contact the helpdesk while the window is still active if you encounter a technical issue. The toll-free number 1800 210 0175 can guide you through upload errors or login problems — but helpdesk support for correction portal issues is only meaningful while the window is open.
