- GST Registration is completely free — no government fee is charged. Apply at gst.gov.in.
- West Bengal is not a special category state — thresholds are ₹40 lakh for goods and ₹20 lakh for services. Crossing either limit makes registration mandatory.
- Certain businesses must register regardless of turnover — interstate suppliers, e-commerce sellers, and exporters fall under Section 24 of the CGST Act, 2017, and must register from Day 1.
- In 2026, Aadhaar authentication is mandatory for all GST registrations. Without it, physical verification by a GST officer is triggered, extending the process.
- Penalty for not registering under GST is ₹10,000 or 10% of the tax due, whichever is higher — under Section 122 of the CGST Act. Deliberate evasion attracts up to 100% penalty.
GST Registration in Siliguri is one of the most searched compliance requirements for the city’s traders, wholesalers, retailers, and service providers. Siliguri is North Bengal’s primary commercial hub — home to a dense network of garment markets, electronics shops, hospitality businesses, logistics operators, and cross-border traders serving Nepal, Bhutan, and Bangladesh. For businesses at this scale of commercial activity, GST Registration in Siliguri isn’t optional — it’s the legal foundation of operations.
This guide covers everything specific to Siliguri: the applicable thresholds under West Bengal’s GST jurisdiction, the mandatory registration categories under Section 24 of the CGST Act, the step-by-step online process at the official GST portal, the Composition Scheme for small traders, and the penalties for non-compliance. All information is verified against current law and GST portal guidance as of June 2026.
1 Is GST Registration in Siliguri Mandatory for Your Business?
The answer depends on your turnover and the nature of your business. West Bengal is a regular category state — not a special category state — so the standard national thresholds apply. There are two separate triggers for mandatory GST Registration in Siliguri:
| Business Type | Mandatory Threshold (West Bengal) | Registration Trigger |
|---|---|---|
| Goods Suppliers / Traders / Wholesalers / Retailers | ₹40 lakh annual turnover | Cross the limit → register within 30 days |
| Service Providers (consultants, IT, restaurants, transport, etc.) | ₹20 lakh annual turnover | Cross the limit → register within 30 days |
| Interstate Suppliers (any goods or services sold outside West Bengal) | ₹0 (no threshold) | Mandatory from Day 1 under Section 24 CGST Act |
| E-commerce Sellers (Amazon, Flipkart, Meesho, etc.) | ₹0 for goods sellers | Mandatory regardless of turnover |
| Exporters of Goods or Services | ₹0 (no threshold) | Mandatory from Day 1 |
| Reverse Charge Recipients | ₹0 (no threshold) | Mandatory from Day 1 under Section 24 |
Aggregate turnover is calculated on an all-India basis per PAN — not just your Siliguri location. If you have branches or businesses in other states, all turnover is combined. Exempt supplies and exports are included in the aggregate turnover calculation even though they may not attract GST.
2 Who Must Register for GST Regardless of Turnover — Section 24 Explained
Section 24 of the CGST Act, 2017 overrides all turnover thresholds. These categories of businesses in Siliguri must obtain GST Registration before making any taxable supply — even if their annual turnover is ₹1:

The GST registration process is entirely online at gst.gov.in. You don’t visit any government office. However, all supporting documents must be uploaded in PDF or JPEG format. Here is the complete document checklist based on the most common business types in Siliguri:
📄 For Proprietors / Individuals

4 Step-by-Step Process for GST Registration Siliguri — Online at gst.gov.in
GST Registration in Siliguri is free of charge and processed entirely online. Here is the exact process as it works in 2026:
-
1
Visit the GST Portal and Start New Registration
Go to gst.gov.in → Services → Registration → New Registration. Select “Taxpayer” as the type. Enter your state (West Bengal), district (Darjeeling / Jalpaiguri for Siliguri area), legal name as per PAN, PAN, email address, and mobile number.
-
2
Receive and Use the Temporary Reference Number (TRN)
After OTP verification of your email and mobile, a Temporary Reference Number (TRN) is sent. Log in again using this TRN within 15 days to continue and complete Part B of the registration form. Do not let the TRN expire.
-
3
Complete Part B — Business Details and Document Upload
Fill in full business details: business type, principal place of business address (Siliguri), nature of business activities, HSN/SAC codes for your goods/services, bank account details, and details of promoters/directors. Upload all required documents in PDF or JPEG format.
-
4
Aadhaar Authentication (Mandatory in 2026)
All GST registrations in 2026 require Aadhaar authentication. An OTP is sent to the Aadhaar-linked mobile number of the proprietor / authorised signatory. Complete authentication immediately. If you cannot authenticate via Aadhaar, the application is flagged for physical verification by a GST officer — which adds 7–21 days to the timeline.
-
5
Submit with DSC or EVC
Verify and submit the application using a Digital Signature Certificate (DSC) for companies and LLPs, or Electronic Verification Code (EVC via OTP) for proprietors and partnerships. Receive an Application Reference Number (ARN) on your registered mobile and email.
-
6
GSTIN Issued — Certificate Available for Download
The GST officer reviews the application. If everything is in order, your GSTIN (15-digit Goods and Services Tax Identification Number) is issued and the GST Registration Certificate is available to download via Services → User Services → View/Download Certificates. Processing takes 2–7 working days for clean applications.
5 Composition Scheme — The Right Option for Small Traders in Siliguri?
Many small traders and shop owners in Siliguri’s markets — from garment retailers to grocery dealers — are eligible for the GST Composition Scheme. This scheme significantly reduces compliance burden and tax calculation complexity. Here’s how it compares to regular GST registration:
| Feature | Regular GST Registration | Composition Scheme |
|---|---|---|
| Eligibility Turnover | Any turnover | Up to ₹1.5 crore (traders/manufacturers); up to ₹50 lakh (service providers) |
| Tax Rate | Standard rates (5%, 12%, 18%, 28%) | 1% for traders, 2% for manufacturers, 5% for restaurants, 6% for service providers |
| Tax Base | On taxable value of each supply | On total annual turnover (flat rate) |
| Returns | GSTR-1 (monthly/quarterly) + GSTR-3B (monthly) | GSTR-4 (annual) — significantly simpler |
| Input Tax Credit (ITC) | Can claim ITC on purchases | Cannot claim ITC |
| Interstate Supply | Allowed | Not allowed — only intra-state supplies |
| Tax Invoice | Can issue tax invoice | Must issue Bill of Supply — cannot charge GST separately |
| Best For | Businesses with significant input purchases, interstate trade, or B2B clients | Small local retailers, restaurants, traders with primarily local clientele |
Composition Scheme opt-in deadline: To opt for the Composition Scheme for FY 2026-27, the CMP-02 form must be filed at gst.gov.in by 31 March of the preceding financial year. You cannot switch mid-year. If you crossed the Composition limit, you are automatically shifted to the regular scheme from the date of exceeding the limit.

Operating without GST Registration when it’s mandatory is a statutory offence under the CGST Act, 2017. The penalties are set out in Section 122 and are not discretionary — they are applied by the GST officer upon detection.
| Offence | Penalty | Section |
|---|---|---|
| Failure to obtain GST registration when liable | ₹10,000 or 10% of tax due — whichever is higher | Section 122(1) CGST Act |
| Deliberate tax evasion / suppression of turnover | Up to 100% of the tax amount | Section 74 CGST Act |
| Supplying goods / services without an invoice | ₹10,000 or tax involved — whichever is higher | Section 122(1)(i) CGST Act |
| Collecting GST but not depositing with government (beyond 3 months) | ₹10,000 or tax collected — whichever is higher | Section 122(1)(iii) CGST Act |
| Not filing GST returns (GSTR-3B) | ₹50/day (nil return) or ₹100/day (regular), up to ₹5,000 late fee | Section 47 CGST Act |
Practical example: A Siliguri trader with ₹50 lakh annual turnover crosses the ₹40 lakh threshold and fails to register. Tax due at 18% GST on the excess ₹10 lakh = ₹1.8 lakh. Penalty = 10% of ₹1.8 lakh = ₹18,000 — but the ₹10,000 minimum would apply if 10% comes to less. In addition, all the unregistered supply remains taxable, back-dated from the date of exceeding the threshold. This can result in a significant demand notice.
8 Post-Registration GST Compliance for Siliguri Businesses
Obtaining your GSTIN is just the start. Every GST-registered business in Siliguri — whether a regular taxpayer or a Composition dealer — has ongoing filing obligations. Missing them attracts automatic late fees.
| Return | Who Files | Frequency | Due Date |
|---|---|---|---|
| GSTR-1 | Regular taxpayers — outward supplies | Monthly (turnover >₹5cr) or Quarterly (QRMP scheme) | 11th of following month |
| GSTR-3B | Regular taxpayers — summary return with tax payment | Monthly | 20th of following month |
| GSTR-4 | Composition Scheme dealers | Annual | 30 April of next FY |
| GSTR-9 | Regular taxpayers — annual return | Annual | 31 December of next FY |
| GSTR-9C | Turnover >₹5 crore — reconciliation statement | Annual | 31 December of next FY |
For traders under the QRMP (Quarterly Return Monthly Payment) scheme — available to those with aggregate turnover up to ₹5 crore — GSTR-1 is filed quarterly but tax is paid monthly via a challan. This scheme reduces the number of returns significantly and is particularly suited for small and medium traders in Siliguri.

9 Final Word — Getting GST Registration in Siliguri Right in 2026
GST Registration in Siliguri is free, entirely online, and typically completed within a week when documents are in order. For North Bengal’s traders, wholesalers, service providers, and exporters, a valid GSTIN is no longer just a compliance requirement — it’s a business asset that enables interstate trade, ITC claims, bank credit access, and e-commerce participation.
The 2026 Aadhaar authentication mandate has streamlined approvals for most applicants, but created delays for those with Aadhaar-mobile linkage issues. Getting this right before you apply saves significant time. The Composition Scheme remains an excellent option for local retailers and small traders in Siliguri’s markets — significantly simpler returns and a flat tax rate in exchange for not claiming ITC or doing interstate trade.
Whether you’re a first-time registrant crossing the turnover threshold, an e-commerce seller needing a GSTIN before your first order, or an exporter managing cross-border trade through NJP — Validraft’s compliance team handles GST Registration in Siliguri end-to-end with verified accuracy.
