GST registration is mandatory once turnover crosses the threshold for your state and category of supply, and it is mandatory from day one regardless of turnover for inter-state suppliers, e-commerce sellers, and businesses liable under reverse charge. Registering also lets you claim input tax credit on purchases, which for most B2B businesses is the difference between competitive pricing and losing bids.
Who needs this
- Businesses crossing the turnover threshold for goods or services
- Anyone supplying goods across state lines
- Sellers on e-commerce marketplaces, from the first rupee of supply
- Exporters, who need registration to claim refunds or file a letter of undertaking
- Businesses whose customers insist on a GST invoice
Documents required
This is the usual list. Depending on your state and your specific facts, an authority may ask for more — we tell you at the scope stage rather than midway through.
- PAN of the business and of the proprietor, partners or directors
- Aadhaar of the authorised signatory, for e-verification
- Certificate of incorporation, partnership deed or equivalent constitution document
- Proof of the principal place of business — electricity bill, rent agreement and owner's no-objection certificate
- Bank account details — cancelled cheque or bank statement
- Photographs and a board resolution or authorisation letter for the signatory
How we handle it
1. Applicability and structure
We confirm whether registration is actually required, whether the composition scheme suits you better, and how many registrations you need across states.
2. Application
REG-01 is filed with supporting documents and Aadhaar authentication.
3. Clarifications
Where the officer issues REG-03 seeking clarification, we draft and file the reply within the window — this stage is where most rejections happen.
4. GSTIN and setup
On approval you receive the GSTIN and registration certificate. We set up the return calendar and, where relevant, e-invoicing and e-way bill access.
Fees and timeline
Physical verification of premises is now common where Aadhaar authentication is not completed. Getting the address proof and the no-objection certificate right at the outset avoids a rejection and a fresh application.
We quote after a short conversation rather than publishing a single number, because the honest answer depends on your state, your turnover and your category. Call +91 98999 00300 or send the details through the enquiry form.
Common questions
What is the turnover threshold?
It differs by state and by whether you supply goods or services, and special category states have lower limits. We check your specific position rather than quoting a single number.
Do I need separate registration for each state?
Yes. GST registration is state-specific, and a business operating from premises in more than one state needs a registration in each.
Can registration be cancelled if I stop trading?
Yes, and it should be — an active GSTIN carries the obligation to file nil returns, and late fees accrue whether or not you traded. Revocation is possible if cancellation was ordered by the department.
How long does it take?
Where Aadhaar authentication succeeds and documents are clean, it is quick. Physical verification cases take longer.
