---

### 1) Documents required for TIN/CST/GST Registration:

* Proof of Business Address (Electricity bill, rent agreement, etc.)
* Identity Proof of the Proprietor/Partners/Directors (PAN card, Aadhaar, Passport)
* PAN Card of the Business (if applicable)
* Partnership deed / Incorporation Certificate (if applicable)
* Passport size photographs of the applicant
* Bank account details (cancelled cheque, bank statement)
* Copies of invoices or documents related to business (sometimes needed)
* Proof of business constitution (Partnership deed, MOA/AOA for companies)

---

### 2) Where to apply and whom to meet:

* Visit your **State Commercial Tax Department / VAT office** for TIN and CST registration.
* For GST, you need to register online on the **GST Portal** ([https://www.gst.gov.in](https://www.gst.gov.in)).
* In the VAT system (pre-GST), CST is handled by the State VAT department.
* You may approach the local VAT officer or Assistant Commissioner of Commercial Taxes.
* For GST, the entire process is online; you don't need to visit the department physically in most states.

---

### 3) Fees or charges:

* Usually, **TIN/CST registration is free** or nominal fees applicable in some states.
* For GST registration, there is **no fee**.
* Some states may charge a small processing fee for VAT/CST registration.

---

### 4) Time for getting the number:

* TIN and CST number generally issued within **7-15 working days** after application and verification.
* GST registration is usually done within **3-7 working days** after online application.

---

### 5) Prequalification:

* No special qualification is required.
* You must be engaged in taxable goods trading or sale of goods.
* Business premises and documents as proof of existence are essential.
* You should not have any pending tax dues or illegal activities.

---

### 6) Operating without TIN:

* If you don’t have a TIN, you **cannot collect or pay VAT/CST legally**.
* You **may face penalty and legal issues** for not having TIN but continuing business.
* Buyers and suppliers may refuse to deal without valid TIN as it affects their input tax credit.
* It’s advisable to get TIN registration before starting regular trading operations.
