Quick answer: GST registration is compulsory once your turnover crosses ₹40 lakh for goods or ₹20 lakh for services in a financial year (Gujarat is a normal-category state — these are the limits that apply here). Below that, registration is optional but sometimes still worth doing. Once registered, monthly or quarterly returns and Vadodara-specific compliance follow — this page covers both.
GST registration is usually the first compliance step for a new business, and the one most often gotten wrong — either registered too late, or registered correctly but with the wrong return frequency or scheme. Here's the factual position on thresholds, documents, and what follows registration.
When GST registration is compulsory
| Business type | Compulsory registration once turnover exceeds |
|---|---|
| Supplier of goods | ₹40 lakh in a financial year |
| Supplier of services (or goods + services) | ₹20 lakh in a financial year |
| Voluntary registration | Allowed below the threshold — some businesses register early to claim input tax credit or because a client requires a GSTIN to pay them |
Some categories must register regardless of turnover — inter-state suppliers, e-commerce sellers, and businesses required to pay tax under reverse charge, among others. If you're not sure which bucket you fall into, that's worth a direct check before assuming the threshold applies to you.
Documents you'll need

Partnership / LLP
- PAN of the firm and all partners
- Partnership deed / LLP registration certificate
- Photographs and address proof for all partners
- Authorised signatory's Aadhaar

Private limited company
- Certificate of Incorporation, MOA/AOA
- Company PAN
- PAN, Aadhaar and address proof for all directors
- Board resolution appointing the authorised signatory
- Bank details and business address proof
Registration is filed on the GST portal; you get an Application Reference Number (ARN) immediately, and the GSTIN follows once the application and documents clear verification — timing depends on how complete the filing is, which is the main thing we control for clients.
What we handle beyond registration
- Return filing on schedule — monthly or quarterly, matched to the scheme you're registered under.
- Input tax credit and reconciliation — checking that credit claimed actually matches what's reflected on the portal, before it becomes a mismatch notice.
- Notice and litigation response — a GST notice carries a fixed response window; reading it correctly before replying matters more than replying fast.
- Registration amendments — address changes, additional places of business, adding partners or directors.
Questions we're asked about GST registration
I'm below the ₹40 lakh / ₹20 lakh threshold — do I still need to register?
Not compulsorily, unless you fall into one of the categories that must register regardless of turnover (inter-state supply, e-commerce, reverse charge, and a few others). Many businesses register voluntarily anyway, usually because a client requires a GSTIN to pay an invoice, or to claim input tax credit on purchases.
What happens if I cross the threshold but don't register?
Operating above the threshold without registration exposes you to penalties and interest on the tax that should have been charged and remitted, backdated to when the obligation started — it's worth registering the moment you're close to the limit, not after crossing it.
How long does GST registration take?
You get an Application Reference Number (ARN) as soon as you submit, and the GSTIN follows once the application and documents pass verification. Applications with Aadhaar authentication are to be decided within 7 working days (others within 30 days), and registration is deemed approved if the officer does not act in time; CBIC Circular No. 257/03/2026-GST (26 October 2026) also fixes the list of documents officers may ask for. Complete and consistent documents on the first submission remain the biggest factor.
