Plain-language guide
Who needs GST registration?
GST registration is mandatory in some situations however small your business is, and in others only once your turnover crosses a limit. Here’s how it works in plain language. We’ll confirm what applies to you on the free call.
When your turnover crosses the threshold
Every business that supplies taxable goods or services has to register once its aggregate turnover in a financial year crosses the registration threshold. The limit is different for businesses that supply goods and businesses that supply services, and it is lower in some states.
Aggregate turnover means the total value of all your taxable, exempt and export supplies made across India under the same PAN — not just one branch or one product line. Once you cross the limit, the law gives you 30 days to apply, so if you’re getting close it’s usually worth starting early.
Selling goods to other states
If you sell goods to a customer in another state — for example, from a shop or warehouse in Chennai to a buyer in Bengaluru — you generally need GST registration from the first sale, whatever your turnover. Inter-state supply of goods is one of the cases where the turnover limit doesn’t apply.
Businesses that supply only services across states are treated differently: in most cases they don’t have to register until they cross the threshold. A few exceptions also exist for specific goods, such as some handicrafts, so we check your products before advising.
E-commerce sellers
Selling goods through an online marketplace — any platform that lists your products and collects payment from buyers for you — has usually required GST registration before you list, because the marketplace has to report your sales against your GSTIN.
Since October 2023, small sellers who supply goods only within their own state through a marketplace can, subject to conditions, sell without registering. Many marketplaces still ask for a GSTIN during onboarding. If you sell services through a platform, you usually don’t need to register until you cross the threshold. Selling through your own website, with your own payment gateway, is assessed like any other business.
Other cases where the law requires it
Some businesses have to register regardless of turnover, including:
Casual taxable persons — for example, if you sell at a trade fair or exhibition in a state where you have no fixed place of business.
Businesses that have to pay GST under reverse charge on what they buy.
Non-resident taxable persons making supplies in India.
Agents and brokers who supply on behalf of other registered businesses.
Input service distributors, which share the GST credit on common services across branches.
Suppliers outside India selling online information or database services to consumers in India.
Choosing to register voluntarily
You can register even if the law doesn’t require it yet. Businesses often do this to claim input tax credit on the GST they pay on purchases, to work with larger business clients who prefer GST-registered suppliers, or to be ready before they cross the threshold or start selling to other states.
Once registered, GST rules apply for as long as the registration is active — including in months with no sales — so voluntary registration makes sense when those benefits outweigh the extra compliance. We’ll talk it through honestly on the free call.
One GSTIN per state — and who usually doesn’t need one
GST registration is state-wise. If you have a place of business in more than one state, each state needs its own GSTIN under the same PAN; additional places of business within a state are added to that state’s registration.
Businesses that supply only goods or services that are fully exempt from GST, or only items outside GST, generally don’t need to register — and neither do farmers selling produce from their own cultivation. If you’re not sure where your products fall, we’ll check.
In detail
How it works, what goes wrong, and what comes next
How GST registration works, step by step
Part A on the GST portal: the PAN, mobile number and email of the business are verified by OTP, which generates a Temporary Reference Number (TRN).
Part B (Form GST REG-01): business and promoter details, the authorised signatory, the principal and any additional places of business, the goods and services you supply (HSN / SAC codes) and bank details, with the supporting documents uploaded.
Verification: the application is signed with a digital signature — mandatory for companies and LLPs — or through EVC, with Aadhaar authentication if you opt for it.
Processing: an Application Reference Number (ARN) is generated and an officer reviews the application. If they need anything more, they raise a REG-03 query, which must be answered in REG-04 within 7 working days.
Approval: once approved, your GSTIN is issued and the registration certificate (REG-06) is available on the portal.
Common reasons GST applications are rejected — and how we avoid them
The address proof doesn’t match the premises, or is in someone else’s name without a consent letter or NOC. We check that every address document lines up before filing.
Names differ between the PAN, Aadhaar and bank proof. We compare them line by line.
Uploads are unclear or incomplete — cropped bills, unsigned rent agreements, missing pages. We review every page.
The wrong constitution of business is chosen, or the authorised signatory has no authorisation letter or board resolution. We prepare the right authorisation for your structure.
A physical verification can’t locate the business — no name board, or an incomplete address. We tell you exactly what the officer will look for.
A REG-03 query goes unanswered within 7 working days. We draft and file the reply in time.
After you get your GSTIN
Download your registration certificate (REG-06), display it at your principal place of business, and show your GSTIN on the name board at your premises and on every invoice. If any registration detail changes — address, partners or directors, business activity — the change has to be filed as an amendment (REG-14), within 15 days of the change.
GST compliance applies for as long as the registration is active. Need help after registration? Ask us.

5 to go. Scanned copies are fine — we review everything before filing.
No. BuzyPro TaxCloud Private Limited is a private professional services firm in Chennai. We are not a government website or agency, and we are not affiliated with GSTN, CBIC, DGFT or any government body. You can apply directly on the GST portal at https://www.gst.gov.in yourself; we prepare and file the application on your behalf for a professional fee, and the registration itself is always issued by the department.
Can I apply for GST registration myself?
Yes. GST registration can be done directly on the GST portal at https://www.gst.gov.in, and there is no government fee. We handle it for businesses that want it done right the first time — choosing the right category and HSN / SAC codes, preparing documents that match, filing, and replying to any REG-03 query.
Is there a government fee for GST registration?
No. There is no government fee for GST registration. Our professional fee is shared with you as a clear written quote before you pay.
Can I register with a home address?
Yes. A residential address can be your principal place of business. You need an address proof such as a recent electricity bill or property tax receipt and, if you don’t own the property, a rent agreement or a consent letter / NOC from the owner. The department may verify the address, so the name board and documents should match. Working from home is common for consultants, freelancers and online sellers — we’ll check your documents on the free call.
Do I need GST if I sell online?
Often, yes. Selling goods through online marketplaces has usually required GST registration, though since October 2023 small sellers supplying only within their own state can, under conditions, sell without it. Service providers on platforms usually don’t need to register until they cross the threshold. We’ll confirm on the free call whether it’s mandatory for you.
What is a REG-03 query?
After you apply, the GST officer may need more information or documents before approving your registration. They raise this as a notice in Form GST REG-03, and the reply has to be filed in Form GST REG-04 within 7 working days. Common reasons are an unclear address proof, a mismatch between documents, or a missing authorisation. We draft and file the reply for you — an unanswered query can lead to the application being rejected.
What happens after I get my GSTIN?
Your registration certificate (Form GST REG-06) can be downloaded from the GST portal. You need to display the certificate at your principal place of business, show your GSTIN on the name board at your premises and on your invoices, and keep your details on the portal up to date. GST compliance applies from then on, for as long as the registration is active. Need help after registration? Ask us.
Can I register voluntarily if my turnover is below the threshold?
Yes. Voluntary registration lets you claim input tax credit and issue tax invoices to business clients. In return, GST rules apply for as long as you stay registered, even in months with no sales. The registration can be cancelled later, subject to the conditions in the law. We’ll help you decide whether it’s worth it for your business.
Do I need Aadhaar authentication?
You can opt for Aadhaar authentication while applying. When it succeeds, approval is usually quicker. If you don’t opt for it, or the application is flagged for checks, the department may physically verify your premises, and in some states it asks for biometric verification at a GST Suvidha Kendra. We guide you through whichever applies.
Can one business have more than one GSTIN?
Yes — one for each state where it has a place of business, all under the same PAN. Additional shops, offices or warehouses within the same state are added to that state’s registration rather than getting a new GSTIN.
