A Challan Identification Number (CIN) is a unique 17-digit code generated as proof that a tax payment has been successfully deposited in the government’s account. Whether you pay Income Tax, TDS, or Corporate Tax, the bank issues a challan receipt (counterfoil) containing this CIN.
When you ask “what is Challan Identification Number,” you are asking for the transaction receipt that links your payment to the Income Tax Department’s OLTAS (Online Tax Accounting System). Without the CIN, you cannot prove you paid the tax.
What Does CIN Number Mean?
The 17-digit code is not random. It is structured as:
- 7 Digits: BSR Code of the Bank Branch.
- 8 Digits: Date of Deposit (DDMMYYYY).
- 5 Digits: Challan Serial Number.
Example: 05103080104202300012
Why CIN is Important
- Filling ITR: When filling the “Tax Paid” schedule in ITR, you must enter the CIN (BSR + Date + Serial) for Self-Assessment Tax.
- Tracking Status: You can check if the money reached the government using CIN.
- Correcting Errors: If you paid under the wrong head, the bank needs the CIN to correct the challan.
Where is CIN Number Used?
- Form 26AS: The CIN appears in Part C of Form 26AS once the bank uploads the data.
- TDS Returns: Deductors must quote the CIN of the TDS payment in their quarterly returns.

Common Problems or Errors
- CIN Not Found: Banks take 2-3 days to upload data. If you check immediately, it might say “No Record.”

Important Things to Remember
- Always save the PDF of the challan immediately.
- Ensure the CIN in your ITR matches the challan exactly.
- If you are a deductor, use the CIN to file TDS returns linked to your TAN Number.
