CAT 2026 Fee Concession: SC, ST, OBC and PwD Guide

You belong to a reserved category, the registration window is open, and you are stuck on one screen: do you pay the full fee or the lower one? A wrong move here feels costly either way. Claim a concession you do not qualify for and your form can be flagged. Pay full when you were entitled to pay less, and you have simply overpaid. The CAT 2026 fee concession exists to remove exactly this guesswork, but it only helps if you know which category it covers and what proof the IIMs expect.

This guide covers who qualifies, the rough fee bands by category, the certificates you need, and what happens if a category claim is found invalid. One caution first: the exact rupee amounts shift from year to year, so treat every number here as a typical band and confirm the live CAT 2026 figure in the official notification on iimcat.ac.in before you pay.

Who qualifies for a CAT fee concession

The fee split follows your category, and the line is simpler than most aspirants assume. SC (Scheduled Caste), ST (Scheduled Tribe), and PwD candidates pay a concessional registration fee. Everyone else, which means General and NC-OBC candidates, pays the standard fee. PwD here covers candidates with a recognised disability, sometimes labelled DAP (Differently Abled Persons) in the official forms; the terminology varies, but the benefit attaches to the same group.

The grouping that trips people up is NC-OBC. Non-Creamy Layer OBC candidates do receive reservation benefits at the admission stage, so it feels natural to expect a fee break too. But the registration fee does not work that way. NC-OBC sits with General at the standard rate, and the concession is built around SC, ST, and PwD status only.

If you are still preparing, the CAT exam overview page lays out the section structure and timeline so registration does not pull focus from your study plan. Getting the category right is a five-minute task if your documents are in order, and a multi-day headache if they are not.

The fee structure by category

The table below shows the two fee bands seen in recent cycles. Read the amounts as typical ranges, not as confirmed CAT 2026 figures.

Two practical points sit behind that table. First, the concessional fee is roughly half the standard, but that is a pattern across years, not a promise for 2026, so confirm the exact CAT 2026 fee in the official notification on iimcat.ac.in. Second, the fee usually rises a little most years, which makes an old screenshot from a senior or a coaching forum a weak reference.

There is no separate partial waiver beyond these two bands, and CAT runs no sliding scale or income-based reduction at the registration stage. You either fall in the concessional group and upload proof, or you pay the standard fee. If you are tracking when this window opens and closes, the CAT 2026 important dates calendar maps the registration period against the rest of the cycle.

The certificates you need, and the format

The concession is only as good as the certificate behind it. Each category has its own document, and the format matters as much as the content: a genuine certificate in the wrong format can still be rejected.

SC and ST candidates need a caste or community certificate issued by a competent authority in the prescribed central-government format. The authority is usually a Tehsildar, SDM, or an equivalent revenue officer. ST candidates follow the same logic with the tribe certificate. These certificates do not expire annually, but the name, photograph linkage, and issuing authority all have to be clean.

NC-OBC candidates need an OBC Non-Creamy Layer certificate, and this one has a catch most people miss: it must be valid for the current financial year. The Non-Creamy Layer status is checked against recent income, so an OBC certificate issued two years ago will not be accepted even if your caste status has not changed. They still upload it for admission reservation purposes, even though they pay the standard fee.

PwD/DAP candidates need a disability certificate from the notified medical authority, usually a government medical board, stating the type and extent of disability. If you intend to use a scribe or request compensatory time on exam day, this certificate feeds into that process too, so getting it right early helps twice.

Common reasons category certificates get rejected

Most rejections are avoidable and come from a short list of recurring problems. None are about whether you genuinely belong to the category; they are about whether the document proves it cleanly.

• An expired NC-OBC certificate. The single most common cause. The Non-Creamy Layer certificate must be current for the relevant financial year, and an older one, even by a year, is treated as invalid.
• Wrong format or wrong authority. A certificate that does not follow the prescribed central-government format, or that was issued by an authority not recognised for this purpose, can be rejected even when the underlying claim is true.
• Name mismatch. If the name on the certificate differs from the name on your application, even by an initial, a middle name, or a spelling variant, the document may not be accepted. Match them exactly.
• An illegible scan. A blurry photo, a cut-off seal, or a low-resolution upload where the signature cannot be read is a frequent reason for a document being returned.
• The wrong category selected on the form. Selecting General when you meant NC-OBC, or ticking a category whose certificate you cannot produce, creates a mismatch between what you claimed and what you uploaded.

If you catch one of these after submission, your options are limited and time-sensitive. Check the CAT 2026 form correction window to see which fields can be edited later, but treat it as a backup rather than a plan, since category and fee-linked fields are not always editable once paid.

What happens if your category claim is found invalid

This part is worth being blunt about. A category claim is not just a fee setting; it feeds into reservation and shortlisting, so the IIMs verify it seriously, often again at the admission stage.

If a claim is found invalid, the benefit attached to it can be withdrawn, and that plays out in a few ways. The difference in registration fee may become due, so a concession claimed wrongly can mean paying the gap later. Your reserved-category status may not be recognised for shortlisting, which moves you to the General pool with its higher cutoffs. And in some cases the application or candidature itself can be rejected, including after you have appeared, if verification fails at a later stage.

None of this should scare a genuine reserved-category candidate. If your certificate is valid and correctly formatted, the concession is straightforward and the check is routine. The risk lives in mismatches, expired documents, and wishful category selection, all of which you control before you pay.

A pre-payment checklist to pay the right fee once

The goal is to get through registration in one clean pass, with the right category, certificate, and fee, so you never have to redo it. Run this sequence before you open the payment screen, not during it.

Build a little buffer into this. If your NC-OBC certificate is from a previous year, apply for a fresh one well before the deadline, since revenue offices can take days to issue it. If your name appears differently across your documents, sort that out first rather than gambling on the verifier overlooking it.

Once the fee is paid, do not assume the category field stays open for edits. Some fields lock after payment, which is why you verify before you pay. If a genuine error slips through, your first stop is the official process, and your second is the CAT 2026 helpline channels published in the notification. With the fee settled, put your energy into the exam itself: work through topic-wise CAT practice questions and use the CAT score predictor to track where your prep stands.
