Home / GST guide
A practical guide for businesses in Malda and West Bengal: what GST is, the registration limit, the documents required, GST return due dates and the Acts that govern it.
1 · Concept
GST came into force on 1 July 2017 and replaced excise, service tax, VAT, entry tax and several other levies. It is a destination-based tax charged on each supply of goods or services, with credit for tax paid on inputs, so tax is borne only on the value added at each stage.
2 · Requirement & criteria
Registration is required once aggregate turnover crosses the threshold in a financial year (Section 22, CGST Act). Aggregate turnover is counted on an all-India basis for the same PAN and includes taxable, exempt, export and inter-state supplies.
| Type of supplier | Normal states (incl. West Bengal) | Special category states |
|---|---|---|
| Exclusively goods | ₹40 lakh | ₹20 lakh |
| Services, or goods and services | ₹20 lakh | ₹10 lakh |
Special category states include Manipur, Mizoram, Nagaland and Tripura, and some others at the ₹20 lakh level for goods. The ₹40 lakh goods limit does not apply to suppliers of certain notified items such as ice cream, pan masala and tobacco.
A business below the threshold may still register — useful when customers are registered businesses that want input tax credit, or when selling to government departments.
3 · Composition scheme
Under Section 10, small taxpayers pay a fixed percentage of turnover and file fewer returns. In exchange they cannot claim input tax credit, cannot collect GST from customers, and cannot make inter-state outward supplies.
| Category | Turnover limit | Rate |
|---|---|---|
| Manufacturers and traders | ₹1.5 crore (₹75 lakh in special category states) | 1% |
| Restaurants (no alcohol) | ₹1.5 crore | 5% |
| Service providers | ₹50 lakh | 6% |
4 · Documents required

6 · Returns
Small taxpayers with turnover up to ₹5 crore may opt for QRMP — quarterly returns with monthly tax payment. Returns cannot be filed once three years have passed from their due date.

| GSTR-3B | Summary of sales, ITC and tax paid | Regular taxpayers | 20th of next month; QRMP: 22nd or 24th after the quarter (24th for West Bengal) |

| GSTR-7 | GST deducted at source | TDS deductors (e.g. government departments) | 10th of next month |

| GSTR-9 | Annual return | Regular taxpayers (optional up to ₹2 crore turnover) | 31 December after the year |
| GSTR-9C | Reconciliation statement | Turnover above ₹5 crore | 31 December after the year |
