GST Registration Online
Get your GSTIN without the back and forth. We check what applies to you, file the application, and follow it through to approval.
Goods and Services Tax applies at every step of the supply chain, with full set-off of the tax you have already paid on your purchases. Registration is entirely online, and once you hold a GSTIN you can charge GST on your invoices, claim input tax credit, and pass that credit to your customers. Whether you need to register depends on your turnover, what you supply, and where you supply it, and a few categories have to register from the very first rupee. AMpuesto works out which applies to you, files the application, and stays with it through to the certificate.

What you will get

- Application filed and followed through to approval
- Support with any clarification the department raises
- Advisory on your return filing obligations once registered
Who needs GST registration?
You must register once your aggregate annual turnover crosses the threshold for your supply type and your state:
| What you supply | Most states | Special category states |
|---|---|---|
| Goods only | ₹40 lakh | ₹20 lakh |
| Services, or goods and services | ₹20 lakh | ₹10 lakh |
Aggregate turnover here means all taxable supplies, exempt supplies, exports, and inter-state supplies made under the same PAN across India, calculated from 1 April of the financial year up to the date you become liable. It excludes inward supplies on which you pay tax under reverse charge, and it excludes the GST and cess itself. Job-worked goods are not counted in the job worker's turnover.
When registration is compulsory regardless of turnover
Some businesses have to register from day one, whatever their turnover:
- Anyone making an inter-state supply of goods
- A person liable to pay tax under reverse charge
- Casual taxable persons without a fixed place of business
- Non-resident taxable persons
- Anyone supplying on behalf of another registered person, such as an agent
- E-commerce operators required to collect tax at source under Section 52
- Persons liable to pay tax under Section 9(5)
- Persons required to deduct tax at source under Section 51
- Input service distributors
- Suppliers of online information and database access services from outside India to an unregistered person in India
Voluntary registration
You can register voluntarily at any turnover, and many small businesses do. A GSTIN lets you claim input tax credit on your purchases, and most corporate clients and e-commerce platforms will not onboard a vendor without one. The trade-off is that once registered you must file GST returns whether or not you trade in a given period, so the decision is worth taking deliberately rather than by default.
The simplified scheme under Rule 14A: registration in three working days
The change most businesses have not heard of
Rule 14A of the CGST Rules introduced an optional Simplified GST Registration Scheme with effect from 1 November 2025, aimed at small and low-risk taxpayers who were previously waiting weeks behind the anti-fraud checks introduced after 2023.
You can opt in if, on your own assessment, your total monthly output tax liability on supplies to registered persons stays within ₹2.5 lakh, counting CGST, SGST or UTGST, IGST, and compensation cess together. You select the Rule 14A option in Part B of Form GST REG-01, and Aadhaar authentication becomes mandatory for the primary authorised signatory and at least one promoter or partner. Where that authentication succeeds, the GSTIN is granted electronically within three working days of your ARN being generated.
Two limits are worth knowing before you opt in. You cannot hold more than one Rule 14A registration in the same state or union territory against the same PAN. And if your B2B output tax later exceeds ₹2.5 lakh a month, you move to normal registration by filing Form GST REG-32, with withdrawal subject to having filed the prescribed returns. We assess whether the simplified route fits you rather than defaulting to it.
How long GST registration takes
| Route | Approval time | Condition |
|---|---|---|
| Rule 14A simplified scheme | 3 working days from ARN | Aadhaar authentication, B2B output tax within ₹2.5 lakh a month |
| Standard registration | 7 working days | Aadhaar authentication successful, no risk flag |
| Where physical verification applies | Up to 30 days | Aadhaar not done, or the application is flagged |
The single biggest cause of delay is a mismatch between the name on your PAN and your Aadhaar, which can send an otherwise clean application into manual review. We check that before filing.
The registration process
Part A of Form GST REG-01
We submit your PAN, mobile number, and email, which are verified by OTP, and the portal issues a Temporary Reference Number.
Part B and documents
Using the TRN we complete the application with your business details and upload the supporting documents, selecting the Rule 14A option where it suits you.
Aadhaar authentication
The authorised signatory and a promoter or partner complete OTP-based Aadhaar authentication, which is what unlocks the faster timelines.
ARN generated
The portal issues an Application Reference Number, and the clock on the approval timeline starts here.
Departmental review
The officer either approves, or raises a query in Form GST REG-03, to which we respond in Form GST REG-04 within the time allowed.
Certificate issued
On approval you receive Form GST REG-06 with your GSTIN, and you can begin charging GST on your invoices.
Registration is PAN-based and state-specific
GST registration is tied to your PAN and to the state where you operate. If you supply from more than one state, you need a separate registration in each. You can also hold more than one GSTIN within the same state against the same PAN where you run separate places of business, though this is not available under the Rule 14A simplified route. Once you become liable to register, you have thirty days from that date to apply.
The composition scheme
Small businesses may prefer the composition scheme, which replaces regular GST with a flat rate on turnover and quarterly filing instead of monthly returns.
Who it suits
Goods up to ₹1.5 croreOpen to suppliers of goods with turnover up to ₹1.5 crore, and to service providers up to ₹50 lakh. It works best for small businesses selling within one state to customers who do not need to claim credit.
What you give up
No input tax creditYou cannot claim input tax credit or collect GST from your customers, and you cannot make inter-state supplies. We run both options against your numbers before you decide.
Benefits of registering
- Legal recognition: you are recognised as a supplier of goods or services, which matters to corporate buyers and platforms.
- Input tax credit: you claim credit for the GST you pay on purchases and set it against the GST you collect.
- Passing credit on: your registered customers can claim credit on what they buy from you, which makes you easier to deal with.
- Wider market: registration is what allows you to sell across state lines and on e-commerce platforms.
- A uniform structure: one indirect tax framework applies across the country, so compliance is easier to plan around.
What happens if you do not register
Operating without registration when you are liable attracts a penalty under Section 122 of ₹10,000 or the tax due, whichever is higher.
You also cannot claim input tax credit for the period you were unregistered, and clients who need your GSTIN for their own credit may simply take their business elsewhere. Registering on time is far cheaper than any of that.
Compliance after registration
A GSTIN brings ongoing obligations, and they apply whether or not you trade in a given period. You file GSTR-1 for your outward supplies and GSTR-3B for your summary and payment, either monthly or quarterly under the QRMP scheme, and GSTR-9 annually where it applies to you. Composition taxpayers file quarterly in CMP-08 with an annual GSTR-4. Your certificate stays valid for the life of the business unless it is cancelled, suspended, or surrendered, except for casual and non-resident taxable persons, whose registration runs for a fixed period. We handle your GST returns too.
What it costs
Government fee: nilThe government charges no fee for GST registration. What you are paying for is getting the application right: the correct classification, a place of business that will survive verification, and a PAN and Aadhaar that match. A rejected or queried application costs weeks.
Why register through a Chartered Accountant
Most GST registration delays are avoidable: a name mismatch between PAN and Aadhaar, an address proof the officer will not accept, or the wrong choice between the simplified route, normal registration, and the composition scheme. Getting those right at the application stage is the difference between three working days and thirty.
If you are still deciding how to structure the business, we also handle proprietorship, LLP, and private limited company registration, and your income tax return and TDS returns alongside GST.
