GST Registration for Traders: Complete 2026 Guide
If you buy and sell goods in India and your turnover has crossed ₹40 lakh (₹20 lakh in a handful of special category states), you need GST registration. If you sell across state lines, sell through Amazon or Flipkart, or make even one interstate B2B sale, you need it regardless of turnover. Registration itself costs nothing on the GST portal, and under the current Rule 14A fast track, an eligible trader with Aadhaar authentication can have a GSTIN in as little as 3 working days.
That's the short version. The rest of this guide covers what actually matters for a trader specifically: the turnover math including the goods-only exception most guides skip, the documents by business structure, the exact online steps, the composition scheme most trader-focused pages don't even mention, and the return-filing and e-way bill obligations that start the day your GSTIN is issued, not after.
Who Counts as a "Trader" Under GST?
For GST purposes, a trader is anyone who buys goods and resells them without changing their form: wholesalers, distributors, retailers, stockists, and resellers of any kind. This is different from a manufacturer (who changes raw material into a new product) or a pure service provider (a consultant, agency, or freelancer). The distinction matters because goods-only traders get a materially higher registration threshold than service providers, which is one of the most commonly misunderstood points in this entire topic.
If your business trades in goods but also earns income from services, even a small amount of commission income, delivery charges billed separately, or installation services, you generally fall under the lower "mixed supplier" threshold rather than the goods-only one. This single detail changes the registration math for a lot of small traders who think they qualify for the higher limit and don't.
What Is GST Registration for Traders?
GST registration is the process of enrolling your trading business under India's Goods and Services Tax law so you can legally charge GST on your sales, claim input tax credit on your purchases, and file GST returns. Once approved, you get a 15-digit GSTIN (GST Identification Number) that appears on every invoice, e-way bill, and return you file from that point onward.

When Is GST Registration Mandatory for a Trader?
Registration becomes mandatory the moment either of these applies:
-
Your aggregate turnover crosses the applicable threshold (covered in detail below), or
-
You fall under one of the categories the law requires to register regardless of turnover.
Categories That Must Register Regardless of Turnover
A trader must register even at zero rupees of turnover if any of the following applies:
-
You make any inter-state supply of goods, even a single sale to a buyer in another state
-
You sell through an e-commerce marketplace such as Amazon, Flipkart, Meesho, or your own e-commerce platform as an operator
-
You are a casual taxable person, for example running a stall at an exhibition or seasonal trade fair outside your home state
-
You are liable to pay tax under reverse charge on any of your inward supplies
-
You are required to deduct or collect tax at source
If none of these apply and you sell only within your own state through your own channels, the turnover threshold is what decides registration.
What Is the GST Registration Turnover Limit for Traders?
This is where traders genuinely get a better deal than service providers, and it's worth understanding the exact conditions rather than just the headline number.
|
Supplier type |
Normal category states |
Special category states |
|
Goods-only trader |
₹40 lakh |
₹20 lakh |
|
Service provider or mixed supplier |
₹20 lakh |
₹10 lakh |
The special category states with lower thresholds include Arunachal Pradesh, Manipur, Meghalaya, Mizoram, Nagaland, Puducherry, Sikkim, Telangana, Tripura, Himachal Pradesh, and Uttarakhand. Assam and Jammu & Kashmir are technically special category states but have opted to use the higher ₹40 lakh goods limit, so treat them as normal-category for this calculation.
The ₹40 Lakh Threshold Has Conditions Attached
To use the higher ₹40 lakh limit, all of these must be true:
-
You supply only goods, no services at all, not even incidentally
-
You are not making intra-state supplies in any of the lower-threshold special category states listed above
-
You do not deal in ice cream, pan masala, or tobacco products, these categories are excluded from the ₹40 lakh benefit and fall back to the ₹20 lakh threshold even for goods-only sellers
If any of these three conditions fails, your goods business registers at ₹20 lakh, not ₹40 lakh.
How Aggregate Turnover Is Actually Calculated
Aggregate turnover is calculated across all your business locations under the same PAN, added together, not state by state. It includes taxable supplies, exempt supplies, exports, and inter-state supplies. It excludes GST itself, compensation cess, and the value of inward supplies you pay tax on under reverse charge.
The part that trips up traders most often: exempt sales still count toward the threshold, even though you don't charge GST on them. If you sell ₹25 lakh of taxable goods and ₹18 lakh of GST-exempt goods in the same year, your aggregate turnover for threshold purposes is ₹43 lakh, past the ₹40 lakh mark, even though a chunk of that never had GST on it.
One narrow exception: if you deal exclusively in goods or services that are wholly exempt from GST, you're not required to register under Section 23, regardless of turnover.
What Documents Are Required for GST Registration for Traders?
Most traders in India operate as sole proprietors or partnerships, so we've split the document list by the structures traders actually use.
If You're a Sole Proprietor (most common for traders)
-
PAN card of the proprietor
-
Aadhaar card, needed for Aadhaar authentication
-
Passport-size photograph
-
Proof of the principal place of business: electricity bill, property tax receipt, or a rent agreement together with a no-objection certificate if the premises is rented
-
Bank account proof: a cancelled cheque, bank statement, or the first page of your passbook
-
HSN codes for the goods you trade in, decided before you start the application, not after
If You're a Partnership Firm
Everything above, plus the partnership deed, PAN of the firm itself, and PAN and address proof for every partner.
If You're an LLP or Private Limited Company
The incorporation certificate, LLP agreement or MOA/AOA depending on structure, a board resolution or authorisation letter naming the signatory, and a Digital Signature Certificate for that signatory, this is mandatory for LLPs and companies, optional for proprietorships.
A detail worth flagging specifically for traders: your address, name, and PAN spelling need to match exactly across every document you upload. Address or name mismatches are the single most common reason GST officers issue a clarification notice on a trading business application, more so than for service businesses, because traders often have separate documents for a warehouse, a shop, and their personal residence, and those three rarely match perfectly on the first try.
How to Register for GST as a Trader Online?
-
Go to gst.gov.in and navigate to Services > Registration > New Registration.
-
Select "Taxpayer," then enter your state, business legal name, and PAN.
-
Complete OTP verification on your mobile number and email to receive a TRN (Temporary Reference Number). The TRN is valid for only 15 days, so don't let a half-finished application sit longer than that.
-
Log back in using the TRN and complete Part B: business details, additional places of business (relevant if you run more than one shop or warehouse), promoter or partner details, the HSN codes for your goods, and bank account information.
-
Opt in to Aadhaar authentication for the authorised signatory. This one decision affects your approval timeline more than anything else in the form, covered in the next section.
-
Upload every document in the specified format and file size.
-
Submit using a DSC (mandatory for companies and LLPs) or EVC, an OTP-based option available to proprietors and partnerships.
-
You'll receive an ARN (Application Reference Number) by SMS and email. This confirms your application has been filed and gives you something to track.
-
Once approved, download your GST Registration Certificate, Form REG-06, from Services > User Services > View/Download Certificate.
The Fast Track Most Trader Guides Don't Mention: Rule 14A
Since 1 November 2025, CBIC's Notification No. 18/2025-Central Tax introduced Rule 14A, a self-declaration route that gets an eligible applicant's GSTIN deemed-approved within 3 working days, against the standard 7 to 30 day timeline. To qualify, your estimated monthly output tax liability on B2B supplies (sales to other registered businesses) must not exceed ₹2.5 lakh, and you must complete Aadhaar authentication for the authorised signatory.
This matters a lot for small and mid-sized traders, since B2C retail sales don't count toward that ₹2.5 lakh cap at all. A trader doing high-volume retail with modest B2B wholesale alongside it can often qualify. The trade-off is that Rule 14A registration is capped at one GSTIN per PAN per state, and if your B2B liability later exceeds the cap, you file Form GST REG-32 to withdraw from the scheme (before 1 April 2026 this requires at least three months of returns already filed; from 1 April 2026 onward, just one tax period's returns).
If you skip Aadhaar authentication entirely, or your application gets flagged for physical verification of your business premises, expect the standard 7 to 30 working day timeline instead, and a visit to a GST Suvidha Kendra for biometric checks in some states.
How Much Does GST Registration Cost for Traders?
The government charges zero rupees for GST registration itself, no matter your business type or turnover. If you file directly on gst.gov.in yourself, that's the entire cost.
What you may pay for is professional help, a CA, tax consultant, or a filing service, to prepare and submit the application, review your documents before upload, and handle any officer query on your behalf. Rates vary by provider and by how complicated your registration is (a proprietorship with one shop is simpler than a partnership with a warehouse in a second state). Ask upfront whether the quoted price covers query handling and the certificate download, or whether those come as extras later.
Skipping registration when you're required to have it isn't free either. Under Section 122, a business that fails to register when liable, or supplies goods without registration, faces a penalty of 10% of the tax due or ₹10,000, whichever is higher. Where the department finds deliberate tax evasion rather than an honest oversight, the penalty rises to 100% of the tax due.
Should a Trader Use the Composition Scheme Instead of Regular Registration?
This is the biggest thing most GST-for-traders content leaves out entirely, and it's genuinely relevant to a large share of small and mid-sized traders.
If your aggregate turnover in the previous financial year was up to ₹1.5 crore, you can opt for the composition scheme instead of regular GST registration. As a trader, you'd pay a flat 1% GST on turnover (0.5% CGST plus 0.5% SGST) instead of the standard rate on each sale, and your compliance load drops sharply: a single quarterly self-assessed payment through Form CMP-08, plus one annual return, Form GSTR-4, instead of the monthly or quarterly return cycle regular taxpayers deal with.
The scheme comes with real restrictions that suit some traders and rule it out for others:
-
No input tax credit on your purchases, you pay 1% on what you sell but can't offset the GST your suppliers already charged you
-
No inter-state outward supply, composition dealers can only sell within their own state
-
You cannot supply goods through an e-commerce operator required to collect tax at source, which rules the scheme out for anyone selling on Amazon or Flipkart
-
You cannot issue a "tax invoice" showing GST charged separately; you issue a "bill of supply" instead, since composition dealers don't collect GST from customers as a line item
In practice, composition suits a small, purely intra-state trader selling to end consumers who doesn't need to claim ITC and isn't chasing large B2B buyers who expect a GST-compliant tax invoice with credit passed through. A wholesaler supplying other GST-registered businesses almost always does better under regular registration, because those buyers want the input credit that only a regular-scheme invoice provides.
What Happens After GST Registration for a Trader?
Getting the GSTIN is the start of your compliance cycle, not the end of the paperwork. A few things need attention in the first month specifically:
Bank account verification within 30 days. Under a GSTN advisory that took effect in late 2025, you must furnish and verify an active bank account in the business's name within 30 days of registration. This has become one of the more common reasons GSTINs get flagged or suspended in 2026, precisely because it's easy to forget once the GSTIN itself is in hand and the pressure of the application is over.
Display your GSTIN at your place of business. Your registration certificate and GSTIN need to be visibly displayed at your principal place of business and any additional locations.
Start invoicing correctly from day one. Every invoice needs your GSTIN, the buyer's GSTIN if they're registered, HSN codes for the goods sold, and the GST rate and amount charged separately from the price. HSN code reporting requirements get stricter as turnover rises, businesses above certain turnover slabs must report HSN codes at a more detailed digit level, so check the current requirement for your turnover band rather than assuming the same digit count applies at every size.
Know your e-way bill and e-invoicing obligations, covered next, since these apply specifically to businesses that move physical goods, which is every trader.
GST Returns and Compliance for Traders
What you file depends on whether you're under regular registration or the composition scheme.
Regular Scheme
-
GSTR-1 (outward supplies): due on the 11th of the following month for monthly filers, or the 13th of the month after quarter-end for QRMP filers, who can still upload B2B invoices monthly through the Invoice Furnishing Facility.
-
GSTR-3B (summary return and tax payment): due on the 20th of the following month if your turnover is above ₹5 crore. Up to ₹5 crore, you can opt into the QRMP scheme and file quarterly, by the 22nd or 24th depending on your state, while still paying tax monthly through Form PMT-06.
-
GSTR-9 (annual return): filed once a year, consolidating the year's GSTR-1 and GSTR-3B data.
Miss a GSTR-3B deadline and you're looking at a late fee of ₹50 per day (capped at ₹10,000) plus 18% annual interest on the unpaid tax. GSTR-1 late fees run ₹200 per day combined CGST and SGST, with turnover-based caps. A nil return is still mandatory even in a month with zero sales; skipping it isn't an option just because there's nothing to report.
Composition Scheme
-
CMP-08: quarterly self-assessed tax payment
-
GSTR-4: annual return
Composition dealers do not file GSTR-1 or GSTR-3B at all, which is the main compliance-load reduction the scheme offers.
GST Invoice for Traders: What Every Invoice Needs
A GST-compliant tax invoice from a regular-scheme trader needs your legal business name and GSTIN, the buyer's GSTIN where applicable, an invoice number and date, the HSN code for each item, quantity and unit price, the taxable value, and the CGST/SGST or IGST amount shown separately, not folded into the price. Composition dealers issue a "bill of supply" instead, since they don't charge GST as a separate line item to the customer.
E-Way Bill and E-Invoicing: The Two Rules Unique to Goods Traders
Because traders physically move goods, two GST obligations apply that a services business never has to think about:
E-way bill: mandatory for any movement of goods worth more than ₹50,000, whether that's an interstate dispatch or, in many states, even an intra-state one above the threshold. Generate it before the goods leave your premises, not after.
E-invoicing: mandatory once your aggregate turnover crosses ₹5 crore in any financial year from 2017-18 onward. Once you cross that line, B2B invoices need to be reported to the Invoice Registration Portal and carry an IRN (Invoice Reference Number) and QR code before they're considered valid for ITC purposes on the buyer's side.
Common GST Registration Mistakes Traders Should Avoid
-
Assuming the ₹40 lakh threshold applies without checking the three conditions attached to it, especially the "no services at all" condition
-
Forgetting that exempt sales still count toward aggregate turnover
-
Registering as a goods-only trader while also earning any service income, then getting flagged later for using the wrong threshold
-
Skipping Aadhaar authentication and unknowingly landing in the slower 7 to 30 day track
-
Not verifying the business bank account within 30 days of getting the GSTIN
-
Choosing composition scheme while still planning to sell through an e-commerce marketplace or ship goods interstate, then having to switch out mid-year
-
Address or name mismatches across PAN, Aadhaar, and the rent agreement or electricity bill used as address proof
-
Treating GST registration as a one-time task and not building GSTR-1/GSTR-3B (or CMP-08/GSTR-4) into a monthly or quarterly routine from month one
GST Registration for Traders Selling Online
If you sell through Amazon, Flipkart, Meesho, or any e-commerce marketplace, GST registration is mandatory from your very first rupee of sales through that platform, the usual turnover threshold does not apply to you at all. The marketplace also collects TCS (Tax Collected at Source) on your sales, which you can claim credit for when filing your returns, but that credit only flows correctly if your registration and GSTIN details on the platform match what's on your GST registration exactly.
GST Registration for Traders: FAQs
Is GST registration mandatory for traders?
It's mandatory once your aggregate turnover crosses ₹40 lakh (₹20 lakh in special category states) for a goods-only trader, or immediately, regardless of turnover, if you sell interstate, sell through e-commerce, or fall under any other Section 24 mandatory category.
What is the GST registration turnover limit for traders?
₹40 lakh in most states for a trader dealing only in goods, ₹20 lakh in special category states. That higher limit doesn't apply if you also provide any services, sell in a lower-threshold special category state, or deal in ice cream, pan masala, or tobacco, all of which fall back to ₹20 lakh.
Can a trader register for GST voluntarily?
Yes. Any business can register voluntarily below the threshold, mainly to claim input tax credit, list on e-commerce platforms that require a GSTIN, or look more credible to B2B buyers who prefer GST-registered vendors.
What documents are required for GST registration for traders?
PAN, Aadhaar, a photograph, address proof of the business premises, bank account proof, and business constitution documents (partnership deed, incorporation certificate) if you're not a sole proprietor. Have your HSN codes decided before you start the form.
How can a trader apply for GST registration online?
Through gst.gov.in, Services > Registration > New Registration. You get a TRN after OTP verification, complete Part B with business and bank details, opt into Aadhaar authentication, upload documents, and submit to receive an ARN.
How much does GST registration cost for a trader?
Nothing, if filed directly on the government portal. Professional assistance, if you choose to use it, is billed separately by whoever you hire.
How long does GST registration take for traders? As fast as 3 working days under the Rule 14A fast track if you're Aadhaar-authenticated and your monthly B2B tax liability is under ₹2.5 lakh. Standard Aadhaar-based applications typically take around 7 working days. Cases needing physical verification can take up to 30 working days.
Can a small trader get GST registration below the turnover limit? Yes, voluntary registration is open to any business regardless of turnover, and the application process is identical either way.
Is GST registration required for traders selling online?
Yes, and it applies from the first sale, not after crossing any threshold, because e-commerce sellers are a mandatory registration category under Section 24.
What happens after a trader gets GST registration?
You need to verify your business bank account within 30 days, display your GSTIN at your place of business, start issuing GST-compliant invoices with correct HSN codes, and begin your return-filing cycle from the very first applicable period, even if that period had no sales.
Do traders have to file GST returns after registration?
Yes. Regular-scheme traders file GSTR-1 and GSTR-3B (monthly or quarterly under QRMP) plus an annual GSTR-9. Composition-scheme traders file CMP-08 quarterly and GSTR-4 annually instead.
Can a trader cancel GST registration?
Yes, through Form GST REG-16, if the business closes, is sold, or drops below the threshold and no longer wants to stay registered voluntarily. A final return and settlement of any outstanding tax liability is still required after cancellation.
Should a trader choose the composition scheme or regular GST registration?
It depends on your buyers and turnover. Composition suits a purely intra-state trader with turnover up to ₹1.5 crore who sells mainly to end consumers and doesn't need input tax credit. Regular registration suits traders who sell interstate, sell through e-commerce, or supply other GST-registered businesses that want ITC passed through on their purchase.
Can a composition scheme trader sell on Amazon or Flipkart?
No. The composition scheme excludes anyone supplying goods through an e-commerce operator required to collect tax at source, which covers every major marketplace. Selling online means regular registration.
What is the penalty for not registering for GST as a trader?
10% of the tax due or ₹10,000, whichever is higher, for a genuine oversight. Where the department establishes deliberate evasion, the penalty is 100% of the tax due.
Do I need a separate GST registration for each state I trade in?
Yes, if you have a place of business in more than one state, you need a separate GSTIN for each state, even under the same PAN and the same business name.
What is an e-way bill and when does a trader need one?
An e-way bill is a document required for moving goods worth more than ₹50,000, generated on the GST portal before the goods leave your premises. It applies to most interstate movement and to intra-state movement above the threshold in many states.
At what turnover does e-invoicing become mandatory for a trader?
Once your aggregate turnover crosses ₹5 crore in any financial year since 2017-18. After that, your B2B invoices need an IRN and QR code from the Invoice Registration Portal to be valid.
Can a trader claim input tax credit on stock purchased before GST registration?
There's a limited provision allowing ITC on inputs held in stock as of the day before registration, subject to conditions and time limits under GST law. This is fact-specific enough that it's worth confirming with a tax professional against your actual stock and invoice dates rather than assuming a blanket answer applies.
What is an HSN code and does every trader need to mention it on invoices?
HSN (Harmonised System of Nomenclature) codes classify the goods you trade for GST rate and reporting purposes. Yes, every registered trader needs to use HSN codes on invoices and returns, though the required number of digits depends on your turnover slab.
Can a trader with only exempt goods skip GST registration entirely?
Yes. Section 23 exempts a person who deals exclusively in wholly exempt goods or services from registration, regardless of turnover, since there's no taxable supply to register against in the first place.
A Note on What This Page Provides
This guide focuses specifically on the goods-only threshold exception, the Rule 14A fast track effective November 2025, the 30-day bank verification requirement, and the composition scheme trade-offs, four areas where trader-specific GST content is either outdated or incomplete on most pages ranking for this topic today. It doesn't replace a conversation with a tax professional about your specific stock, states of operation, or buyer mix, and the composition-versus-regular decision especially benefits from that conversation before you commit.
This page was researched and compiled by Ppsingh, LegalDev's content researcher with 10 years of experience in SEO and compliance content, drawing on the current CBIC notifications and GST portal guidance cited below. It is general information, not a substitute for advice from a chartered accountant or GST practitioner familiar with your specific business.
For the full end-to-end GST registration process covering all business structures, see our GST registration guide. If you've already registered and need help with ongoing compliance, see GST return filing. Traders who haven't yet registered their business structure itself, if you're still operating informally, can also check proprietorship firm registration or MSME/Udyam registration, which pairs well with GST registration for small traders seeking collateral-free loans and other MSME benefits. You can check your application status anytime using our GST ARN status tool, verify any GSTIN using our GST verification tool, or estimate your tax with our free GST calculator.
