How to Fill the IITM BS Application Form, Step by Step

The IITM BS application form is filled in two parts. First you fill a short form and pay the application fee. Then, after payment, you fill in further details and upload your documents. Your application counts only when both parts are done. You can edit the form freely until you pay, but not after. So check everything before you press pay.

For the September 2026 term, the last date to apply is 27 September 2026.

Keep these files ready first

The admissions pages set exact formats and sizes. Scan them before you open the form.

For the JEE route, the proof can be your scoresheet, admit card or registration receipt.

Step by step

1. Open the official page of your programme. Go to study.iitm.ac.in and pick DS, ES, AE or MG. Use the "Apply Now" button on that site only.
2. Use an email you will keep. The DS FAQ says the personal email you apply with cannot be changed. It is used for the whole qualifier and for Foundation registration.
3. Enter your name carefully. An August 2025 IIT Madras letter says the name on UG certificates is taken from the Class 10 certificate. Use the same spelling here to avoid problems later. See the name on your IITM BS certificate.
4. Pick your category honestly.
   • Choose OBC-NCL only if your caste is in the central OBC list and you are non-creamy layer. A state BC or OBC certificate is not the same. Other BC and OBC applicants must choose General.
   • OBC-NCL and EWS certificates must be in the official formats, which you can download from the admissions page.
   • Old certificates may not be accepted. The ES FAQ says outdated certificates are rejected.
5. Answer the JEE question. Say yes only if you were eligible to appear for the current year's JEE Advanced, and upload proof. The handbook says that if your proof is not valid, you are moved to regular entry and must do the qualifier.
6. Choose two exam cities. You must give two different cities, in order of preference. Your centre will be in one of them. You cannot change them for the qualifier after submitting, except in an unavoidable situation, and even then a change is not guaranteed. These choices are for the qualifier only. Writing the qualifier outside India adds an exam facilitation fee.
7. Review everything. This is your last chance to edit.
8. Pay the fee. It is Rs 4,000 for General and OBC applicants, Rs 2,000 for SC, ST or PwD, and Rs 1,000 for SC/ST applicants who are also PwD. Payment is online only: credit card, net banking, wallet or UPI. Debit cards and demand drafts are not accepted. You get a confirmation email from Razorpay.
9. Fill the further details and upload documents. Do not stop after paying. The DS, AE and MG admissions pages say an application without these details and documents is not valid, even if the fee was paid.
10. Wait for verification. It can take up to 3 weeks. Updates come by email, SMS or the dashboard.

The questions after payment

After payment, the form asks for "further details". The admissions pages do not list every question. Answer each one truthfully and in line with your documents. The FAQ says being honest and careful, and uploading correct documents in the correct formats, helps get your application accepted.

If something goes wrong

• Error in the form: email support with your registered email ID, a screenshot of the error and a short description.
• Error after payment: forward the Razorpay confirmation email with your email ID, application number and a screenshot.
• Payment failed but money was deducted: the FAQ says it takes 3 to 4 weeks to reach your bank account.
• A document was returned: you get a chance to upload it again before a deadline. See what to do if your application is returned or rejected.

Save your application number, the Razorpay email and screenshots of each page in one folder.

Common questions

Can I change my exam city after paying?

Not normally. The FAQ says you cannot change qualifier exam cities after submitting. In an unavoidable situation you can write to support, but a change is not guaranteed. More in how exam centres are chosen.

Will I get my fee back if I change my mind?

The DS FAQ says the application fee is not refunded once paid, even if you miss or fail the qualifier. The ES handbook mentions a last date for cancellations but does not give it, so ask ES support quickly if you need to cancel. Fee details are in the qualifier application fee.

Can I apply to DS and ES in the same term?

The admissions pages do not say. The MG FAQ says you cannot study two non-campus BS programmes at the same time. Ask support before you pay two fees.

What happens after I submit everything?

Next come the 4 weeks of qualifier content and weekly assignments. For the September 2026 term, the ES, AE and MG pages give 2 October 2026 as the start of week 1 and 15 November 2026 as the exam date. The full order of steps is in the IITM BS admission process.
