GST Registration for Shop: Limit and Documents
When a shop must register under GST, the documents you need, how to apply online, and what changes in your billing after registration.
Gaddibook Team · · 7 min read
GST registration for a shop is required once your sales cross a turnover limit, and sometimes earlier, depending on how and where you sell. Many small shop owners are unsure whether they need it, what documents to keep ready, and what changes after they register. This guide explains GST registration for shop owners in simple steps.

When is GST registration for a shop mandatory?
The main rule is based on your aggregate turnover in a financial year:
| Business type | Turnover limit for registration |
|---|---|
| Shops selling only goods | ₹40 lakh in most states (₹20 lakh or lower in some special category states) |
| Businesses providing services | ₹20 lakh (₹10 lakh in some special category states) |
| Shops selling both goods and services | Usually the services limit applies; check with your CA |
Aggregate turnover includes taxable, exempt and export sales across all your businesses on the same PAN, but not GST itself. West Bengal, Uttar Pradesh, Bihar and most large states follow the ₹40 lakh limit for goods; confirm your state's limit on the GST portal.
When you must register even below the limit
Registration is compulsory, whatever your turnover, if you:
- sell goods to customers in another state (inter-state supply of goods)
- sell through an e-commerce platform that collects tax at source, except where small intra-state sellers are exempted
- are a casual taxable person, such as a stall at a trade fair in another state
- must pay tax under reverse charge
- act as an agent supplying on behalf of other taxable persons
Should you register voluntarily?
Many shops register before they reach the limit, for good reasons:
- Business customers want GST bills. Contractors, offices and other shops prefer suppliers who give tax invoices, so they can claim input tax credit.
- You can claim input tax credit on your own purchases.
- Bank loans and tenders often ask for a GSTIN.
- Online selling is easier with a GSTIN.
The downside is regular returns and compliance. If most of your customers are consumers and your margins are thin, you may prefer to wait, or register under the composition scheme, which has lower compliance.
Documents needed for GST registration
Keep scanned copies ready before you start:
- PAN card of the business owner (for a proprietorship) or of the firm or company
- Aadhaar card of the proprietor, partners or directors
- Passport-size photograph of the proprietor, partners or directors
- Proof of the shop address: electricity bill, property tax receipt or municipal khata copy
- If the shop is rented: a rent agreement and a no-objection certificate (NOC) from the owner, with the owner's ID proof
- Bank account proof: a cancelled cheque, passbook first page or bank statement showing the account holder's name, account number and IFSC
- For partnerships and companies: partnership deed or certificate of incorporation, and authorisation letter for the signatory
Step-by-step: applying online
- Go to the GST portal and choose New Registration under the Services menu.
- Fill Part A of form REG-01 with your PAN, mobile number and email. Verify with OTPs to get a Temporary Reference Number (TRN).
- Log in with the TRN and fill Part B: business details, promoters, principal place of business, goods and services (HSN/SAC), and bank account.
- Upload the documents listed above.
- Choose Aadhaar authentication. You will receive a link for OTP verification, and in many cases a slot for biometric verification at a GST Suvidha Kendra.
- Submit using an EVC (OTP) or a digital signature. You receive an Application Reference Number (ARN).
- The officer reviews the application. If everything is in order, your GSTIN and registration certificate (REG-06) are issued, usually within a few working days. If the officer asks for clarification, reply within the time given.
There is no government fee for GST registration.
What changes after you register
Once you have a GSTIN, your daily work changes in a few ways:
- Billing: issue tax invoices with your GSTIN, HSN codes and GST for every taxable sale. See how to make a GST invoice.
- Display: show your GSTIN on your signboard and the registration certificate at your shop.
- Returns: file GSTR-1 and GSTR-3B monthly or quarterly, or CMP-08 and GSTR-4 if you chose composition.
- Records: keep purchase bills, sales bills and stock records for at least six years.
- Payments: pay GST before the due date to avoid interest.
A simple example
Sunita runs a stationery and gift shop in Raiganj. Her sales last year were about ₹28 lakh, all to local customers, so she was not required to register. This year, two schools and a coaching centre want to buy from her in bulk, and they ask for GST invoices so they can keep proper accounts. A wholesaler in Siliguri also offers her better rates if she can give her GSTIN.
Sunita decides to register voluntarily. She keeps her PAN, Aadhaar, a photo, the electricity bill of the shop and her bank passbook ready, applies online in about an hour, completes Aadhaar authentication, and receives her GSTIN within a week. She then updates her billing app with the GSTIN, sets HSN codes for her main items, and starts issuing tax invoices.
Her prices to walk-in customers stay almost the same, because she can now claim input tax credit on her purchases. Her new institutional customers are happy, and she files her returns with help from her CA each month.
Choosing between regular and composition after registration
When you apply, you also choose whether to be a regular taxpayer or opt for the composition scheme. Choose regular if you sell to businesses, sell to other states, or want input tax credit. Choose composition if almost all your customers are consumers and you want fewer returns. You can change your choice later, subject to the rules, so pick what fits your business today.
Common mistakes during registration
- Address proof that does not match the address entered in the form.
- A rent agreement without the owner's NOC.
- Choosing the wrong business constitution (proprietorship vs partnership).
- Missing the Aadhaar authentication link, which delays approval.
- Listing too few HSN codes for the goods you sell.
- Using a mobile number or email that belongs to an agent, so you lose access later.
Getting started with GST billing
Once your GSTIN is issued, set up your billing so every bill is right from day one: add your GSTIN and address, enter items with HSN codes and rates, and choose the right invoice format. Gaddibook supports GST and non-GST bills, so you can start before registration and switch on GST the day your GSTIN arrives. See our billing software for retail shops.
