CSAB Counselling 2026: Special Rounds Expected July, Vacant Seats, Important Dates and Cutoff

CSAB Counselling 2026 is the centralised seat allocation process run by the Central Seat Allocation Board to fill the vacant seats left in the NIT+ system after JoSAA counselling ends. It covers seats in 31 NITs, 26 IIITs and around 45 GFTIs, and admission is based on your JEE Main 2026 rank. The JEE Advanced 2026 result was declared on 1 June 2026 and JoSAA 2026 counselling begins on 2 June 2026, so the JEE-based admission cycle has now started. The CSAB 2026 special rounds will start only after the final JoSAA round is over, which is expected in late July 2026.

• JoSAA 2026 Counselling: JoSAA registration and choice filling have started on 2 June 2026, with Round 1 seat allotment expected on 13 June 2026. CSAB special rounds depend on this; they begin only after the last JoSAA round.
• CSAB Special Registration: Registration is expected to open in late July 2026. Last year, CSAB-Special 2025 registration was open from 30 July to 3 August 2025.
• Vacant Seats: Around 13,000+ seats are expected to be on offer. In 2025, CSAB special rounds filled about 13,727 vacant seats, including around 4,500 in NITs and over 3,000 in IIITs.
• Eligibility: You must hold a valid JEE Main 2026 rank. The Class 12 marks rule stays the same — 75% for General and 65% for SC/ST/PwD candidates (or top 20 percentile).

What is CSAB Counselling 2026?

CSAB Counselling 2026 is conducted by the Central Seat Allocation Board to fill the seats that stay vacant in the NIT+ system after JoSAA counselling is over. The NIT+ system means the National Institutes of Technology (NITs), the Indian Institutes of Information Technology (IIITs) and the Government Funded Technical Institutes (GFTIs). Admission in CSAB is based only on your JEE Main 2026 rank, not JEE Advanced.

Every year, JoSAA runs six rounds of joint counselling for the IITs and the NIT+ system. After these rounds, some seats are still left empty because candidates withdraw, do not report, or upgrade to other institutes. CSAB steps in to fill these leftover seats through its own special rounds. This gives you one more chance to get a seat in a top engineering college if you missed out in JoSAA.

So CSAB is the last counselling stage in the JEE Main admission cycle. It is important because it opens up seats in NITs, IIITs and GFTIs that would otherwise go unused. In 2025, the CSAB special rounds offered around 13,727 vacant seats, which shows how many opportunities open up at this stage.

Here is a quick snapshot of CSAB Counselling 2026:

CSAB 2026: JoSAA to Special Rounds Timeline

The CSAB 2026 timeline is linked directly to JEE Advanced and JoSAA. The JEE Advanced 2026 result was declared on 1 June 2026 by IIT Roorkee. This result kicks off the full NIT+ and IIT admission cycle, and JoSAA 2026 counselling begins right after it.

JoSAA 2026 registration and choice filling start on 2 June 2026. The first round of JoSAA seat allotment is expected on 13 June 2026. JoSAA will then run all six rounds across June and July 2026. CSAB special rounds begin only after this — you cannot register for CSAB while JoSAA is still going on.

CSAB 2026 special round registration has not started yet. The CSAB schedule will be released on csab.nic.in only after the final JoSAA 2026 round is over.

Here is how the cycle flows from JEE Advanced to CSAB:

• JEE Advanced 2026 Result: Declared on 1 June 2026. This starts the IIT and NIT+ admission season.
• JoSAA 2026 Registration: Begins 2 June 2026 for IITs, NITs, IIITs and GFTIs.
• JoSAA 2026 Rounds: Six rounds across June and July 2026.
• CSAB Special 2026: Begins after the last JoSAA round, expected in late July 2026.

So as of today, the JEE Advanced result is out and JoSAA is about to begin. CSAB is still a few weeks away. You should first take part in JoSAA, and then move to CSAB if you do not get a seat you are happy with.

CSAB 2026 Important Dates

The CSAB 2026 important dates have not been released officially yet. Since CSAB depends on JoSAA, the dates below are based on the JEE-JoSAA cycle and last year’s CSAB-Special 2025 schedule. You should treat the CSAB dates as expected, and confirm them on csab.nic.in once the schedule is out.

Types of CSAB Counselling 2026

CSAB Counselling 2026 is not a single process. The Central Seat Allocation Board runs different counselling streams for different types of seats. You should know which one fits your case before you apply.

There are three main types of CSAB counselling:

• CSAB-Special Rounds: This is the most common one. It fills the seats that stay vacant in NITs, IIITs and GFTIs after JoSAA ends. Admission is based on your JEE Main 2026 rank.
• CSAB-NEUT (North Eastern States and Union Territories): This handles seat allocation for candidates from the North Eastern states and Union Territories under special nominee quotas. It covers seats reserved for these regions in NITs and other institutes.
• CSAB Supernumerary: This covers supernumerary seats, such as the female supernumerary seats created to improve gender balance and other extra seats in the NIT+ system.

For most JEE Main 2026 candidates, the CSAB-Special rounds matter the most. The DASA (Direct Admission of Students Abroad) scheme is also handled through the CSAB portal, but that is meant for foreign nationals and NRI candidates, not regular Indian JEE Main aspirants.

CSAB 2026 Eligibility Criteria

The CSAB 2026 eligibility criteria are mostly the same as JoSAA, because both use the JEE Main rank. You must have a valid JEE Main 2026 score and rank to take part. Without a JEE Main rank, you cannot register for the CSAB special rounds.

Here are the main eligibility points you should check:

• JEE Main 2026 Rank: You must have a valid rank in JEE Main 2026.
• Class 12 Marks: You should have at least 75% aggregate marks in Class 12 for the General category. For SC, ST and PwD candidates, the requirement is 65%. As an option, you can also be in the top 20 percentile of your board.
• Number of Subjects: You must have passed Class 12 with Physics and Mathematics as compulsory subjects, along with one of Chemistry, Biology, Biotechnology or a technical vocational subject.
• Age Limit: There is generally no upper age limit for NIT+ admissions, but you should check the latest information bulletin for any change.

One good thing about CSAB is that it is open to many types of candidates. You can register for CSAB special rounds whether or not you took part in JoSAA. This includes candidates who got a seat in JoSAA, those who did not, and those who skipped JoSAA fully. So even if you missed JoSAA, you still get a chance through CSAB.

The Class 12 marks rule is set by the NITs and is the same as JoSAA. Always confirm your category eligibility on the official CSAB portal before paying any fee.

CSAB 2026 Registration Process

The CSAB 2026 registration is fully online and is done on csab.nic.in. You will use your JEE Main 2026 application number and password to log in, so you do not need a fresh account. The registration window will open only after JoSAA 2026 ends.

You should complete each step carefully and within the deadline. Many candidates lose their seat because they forget to lock their choices or miss the reporting date. So keep a close watch on the official schedule once it is out.

CSAB 2026 Choice Filling and Locking

Choice filling is the most important part of CSAB 2026 counselling. This is where you tell the system which institute and branch you want. Your seat is allotted based on these choices, your JEE Main 2026 rank, and the seats available.

Here is how you should approach choice filling:

• Add more choices: Fill in as many genuine choices as you can. More choices give you a better chance of getting a seat.
• Order by preference: Put your most wanted college and branch at the top. The system tries to give you the highest possible choice you are eligible for.
• Check vacant seats: CSAB releases a vacant-seat list before choice filling. Use it to add realistic options based on your rank.
• Lock your choices: Once you are sure, lock the choices. If you do not lock, the system may auto-lock your last saved choices at the deadline.

You should be careful while ordering your choices. If you place a branch high up, you must be willing to join it. Once a seat is allotted in CSAB special rounds and you accept it, you have to follow the rules for upgrade or withdrawal set by the board.

CSAB 2026 Participating Institutes and Seat Intake

The CSAB 2026 participating institutes include all the NITs, IIITs and most GFTIs in the country. These are the same institutes that take part in JoSAA. CSAB only deals with the seats that are left vacant in these institutes after JoSAA ends.

The participating institutes are grouped as follows:

• NITs: 31 National Institutes of Technology across India.
• IIITs: 26 Indian Institutes of Information Technology.
• GFTIs: Around 45 Government Funded Technical Institutes.

The number of vacant seats changes every year and is only known after JoSAA is over. The table below shows the CSAB-Special 2025 vacant seats as a reference for what to expect in 2026.

So around 13,000 to 14,000 seats may open up in the CSAB special rounds in 2026. GFTIs usually have the most vacant seats, which gives you a real chance to get into a government technical institute even with a moderate rank.

Documents Required for CSAB 2026

You should keep all your documents ready before CSAB 2026 counselling starts. Missing or wrong documents can lead to your seat being cancelled at the reporting stage. Keep both soft copies and original documents handy.

Here is the list of documents usually required for CSAB counselling:

• JEE Main 2026 Admit Card
• JEE Main 2026 Scorecard or Rank Card
• Class 10 Certificate (for date of birth proof)
• Class 12 Marksheet and Passing Certificate
• Category Certificate (SC, ST, OBC-NCL, EWS) if applicable
• PwD Certificate if applicable
• Photo ID Proof (Aadhaar, PAN, Passport or Voter ID)
• Passport-size Photographs
• Seat Allotment Letter from CSAB
• Medical Fitness Certificate (if asked by the institute)

You must make sure your category certificate is in the correct format and valid for the current year. The EWS and OBC-NCL certificates often need to be from the latest financial year. So check the validity date carefully to avoid problems during verification.

Tips for CSAB 2026 Counselling

CSAB 2026 is your last chance to get a seat in the NIT+ system through JEE Main. A few smart steps can help you make the most of it. These tips are based on how the CSAB special rounds have worked in past years.

Here are some useful tips for CSAB 2026:

• Take part in JoSAA first: Always go through all JoSAA rounds before CSAB. CSAB only fills what JoSAA leaves behind.
• Check the vacant-seat list: Study the official vacant-seat list before choice filling. It tells you which branches are really open.
• Fill many choices: Add as many genuine choices as you can to improve your chances.
• Be realistic with ranks: Use previous-year closing ranks to pick options that match your JEE Main 2026 rank.
• Keep documents ready: Have all certificates ready in the correct format to avoid last-minute trouble.
• Track every deadline: Note the registration, locking and reporting dates so you do not miss any step.

You should also keep some money ready for the seat acceptance fee, as the deadlines are short. With good planning, CSAB can help you turn a missed JoSAA chance into a confirmed seat in a good government engineering college.
