The quick answer
A GST registration decision cannot be made from one monthly sales figure. Identify your supplies, state, PAN-based aggregate turnover and whether a compulsory-registration rule or exemption applies. Turnover is not the same as profit, bank credits or cash collected.
The applicable threshold and any enhanced threshold depend on the law and notifications for your circumstances. Verify those conditions with CBIC and your accountant. A statement that all shops below one amount never need registration can miss important exceptions.
Before you begin
- Goods, services and exempt activities actually supplied.
- Turnover records across relevant establishments under the PAN.
- States of operation and interstate, marketplace or export arrangements.

Activity
Classify the business’s real supplies.
Turnover
Calculate the statutory aggregate turnover.
Conditions
Check state, compulsory rules and exemptions.
Decision
Record the basis and monitor changes.
Work through the steps
Describe goods and services separately
Write down whether you sell goods, provide services or do both. A retailer offering repairs may need a different analysis from a goods-only shop. Include exempt activities rather than omitting them from the description.
Calculate the relevant aggregate turnover
Use PAN-based records and the statutory definition across relevant locations. Do not use net profit or money collected as a substitute. Keep evidence for sales, returns and adjustments.
Identify the applicable threshold
Check Section 22 and current notifications for your activity and state. An enhanced goods threshold has conditions; it is not a universal threshold for every business or every kind of supply.
Check compulsory-registration provisions
Review Section 24 together with exemptions or notifications affecting your transactions. Interstate supplies and marketplace sales need accurate classification. Avoid assuming every online seller follows the same registration rule.
Evaluate voluntary registration
It may suit some B2B businesses, but also creates ongoing compliance responsibilities. Compare customer needs, eligible credits and filing work. A software GST field is not a reason on its own to register voluntarily.
Record the decision and review triggers
Save the rule, assumptions and records used. Monitor turnover and changes in state, services or sales channel. Apply when required and seek timely advice if the business crosses a trigger or changes its activity.
A worked example
Different shops need different first checks
This table illustrates the analysis, not a legal determination for a particular taxpayer.
| Situation | First record | Additional check |
|---|---|---|
| Local goods retailer | PAN-based turnover | Enhanced-threshold conditions and state |
| Retailer with repair services | Goods and services turnover | Applicable mixed-activity treatment |
| Marketplace seller | Supply and platform arrangements | Compulsory rule or exemption |
Identify the correct legal rule before choosing a turnover threshold. Similar-looking shops may have different registration obligations.
Common mistakes to avoid
- Treating cash receipts or net profit as aggregate turnover.
- Ignoring other relevant establishments under the same PAN.
- Assuming voluntary registration removes filing duties in quiet months.
- Using a threshold without checking its activity, state and exception conditions.
Questions you might have
Can an unregistered shop collect GST from customers?
An unregistered person cannot collect an amount as GST simply because the product is taxable. Use the correct ordinary billing treatment and seek advice if registration liability has arisen.
Does Dukanam require every shop to have a GSTIN?
No. Ordinary billing and registered GST-aware billing are different workflows. Enter the actual status and choose features appropriate to the business and plan.
Dukanam
A smart, low-cost choice for small-business GST billing
Dukanam brings billing, purchases, stock, customer balances, payments and reports together. It is built for Indian small businesses that want clear records without a complicated setup.
Best suited to shops that want connected everyday billing and bookkeeping, web and mobile access, and nine product languages. Choose the plan that includes the features you need.
GST-aware billing and preparation depend on your plan. Review records before filing on the GST portal; Dukanam does not directly submit GST returns, government e-invoices or e-way bills.
