GST registration and return filing
Getting the GSTIN is the easy part. Staying compliant month after month — matching input credit, filing on time, answering notices — is where businesses actually get into trouble. We do both.
What the engagement includes
- Threshold and liability assessment
- GSTIN application and Aadhaar authentication
- Correct HSN / SAC classification
- Composition scheme evaluation
- LUT filing for exporters
- Monthly or quarterly return filing
- Input tax credit reconciliation
- Notice and query response

When GST registration is required
Registration under the Goods and Services Tax is compulsory once your aggregate turnover crosses the prescribed threshold, and in a number of cases regardless of turnover at all.
| Type of supply | Normal states | Special category states |
|---|---|---|
| Goods | ₹40 lakh | ₹20 lakh |
| Services | ₹20 lakh | ₹10 lakh |
Registration is mandatory regardless of turnover if you
- Make inter-state taxable supplies of goods
- Sell through an e-commerce operator, or are an e-commerce operator
- Are liable to pay tax under the reverse charge mechanism
- Are a casual taxable person or a non-resident taxable person
- Are required to deduct TDS or collect TCS under GST
- Supply on behalf of another registered person as an agent
- Are an input service distributor
Documents required
| Document | Notes |
|---|---|
| PAN of the business or proprietor | Mandatory in all cases |
| Aadhaar of the authorised signatory | Used for authentication, which speeds up approval |
| Photograph of proprietor / partners / directors | Passport size |
| Constitution proof | Incorporation certificate, partnership deed or LLP agreement |
| Principal place of business proof | Electricity bill, property tax receipt, rent agreement plus NOC |
| Bank account proof | Cancelled cheque or first page of the passbook or a statement |
| Board resolution / authorisation letter | Appointing the authorised signatory |
| Digital Signature Certificate | Mandatory for companies and LLPs |
How registration works
- Liability assessmentWe confirm whether you are required to register, in which states, and whether the composition scheme is worth considering.
- Application filingPart A establishes the PAN, mobile and email; Part B carries the business details, place of business, bank account and authorised signatory.
- Aadhaar authenticationCompleting authentication materially speeds up processing. Where it is not completed, the department may require physical verification of the premises instead.
- ClassificationCorrect HSN codes for goods and SAC codes for services. Getting this wrong causes invoice and return mismatches later.
- Query responseIf the officer raises a query, we respond within the time allowed — an unanswered query results in rejection.
- GSTIN issuedYour registration certificate is issued with the fifteen-digit GSTIN.
Straightforward applications with Aadhaar authentication are usually processed within three to seven working days.
Ongoing return filing
Registration creates an obligation to file, whether or not you had any sales. Nil returns still have to be filed, and late filing attracts a daily late fee plus interest on any tax due.
| Return | What it covers | Frequency |
|---|---|---|
| GSTR-1 | Details of outward supplies | Monthly, or quarterly under QRMP |
| GSTR-3B | Summary return and tax payment | Monthly, or quarterly under QRMP |
| CMP-08 | Statement for composition dealers | Quarterly |
| GSTR-9 | Annual return | Annually, above the prescribed turnover |
| GSTR-9C | Reconciliation statement | Annually, above the higher turnover threshold |
Input tax credit is where money is lost
Credit can only be claimed on invoices your supplier has actually reported. If a supplier does not file, your credit is denied and the cost lands on you. Monthly reconciliation between your purchase register and the auto-populated data is the only way to catch this early enough to chase the supplier. It is a routine part of the filing work we do.
Exporters
A Letter of Undertaking lets you export without paying IGST up front and then claiming a refund. It has to be filed at the start of each financial year. Missing it means blocking working capital in refund claims unnecessarily.
Frequently asked questions
Short answers to what clients ask most often about GST Registration.
Not necessarily — but consider registering anyway if your customers are businesses. Registered buyers want an input tax credit against your invoice, and many corporate and government buyers will not onboard an unregistered supplier. If you sell inter-state goods or through an e-commerce platform, registration is mandatory regardless of turnover.
GST is state-specific. You need a separate registration in each state from which you make taxable supplies. A single office serving customers across India needs only one registration in that state; a business with warehouses in three states generally needs three.
It lets small taxpayers pay tax at a flat rate on turnover with far simpler filing. The trade-off is real: you cannot claim input tax credit, you cannot pass credit to your customers, and you cannot make inter-state outward supplies. It suits a B2C business with mostly local customers, and rarely suits a B2B supplier.
A late fee accrues for each day of delay for each return, along with interest on any unpaid tax. Persistent non-filing leads to blocking of e-way bill generation and eventually to cancellation of registration. Reinstating a cancelled registration is considerably more work than filing on time.
Yes, either voluntarily when you cease business or fall below the threshold, or by the department for non-filing or non-compliance. Note that cancellation does not erase past liability, and final returns still have to be filed. We handle both voluntary cancellation and revocation of a department-initiated one.
Yes. Most notices arise from return mismatches, a gap between GSTR-1 and GSTR-3B, or input credit claimed against invoices the supplier never reported. The important thing is to respond within the time given — an unanswered notice becomes a demand. Send it to us and we will tell you what it actually says.
Get registered, then stay compliant
We handle the GSTIN application and, if you want, the monthly filing that follows — so returns do not become somebody's weekend job.
