Yes. A GST registration can cover both goods and services supplied by the same registered person; you do not need one GSTIN for goods and another for services merely because their nature differs. Update the registration’s goods/services details as needed and classify each supply correctly. Separate registrations may arise because of different States, legal entities/PANs or specific structural choices—not simply because you sell both a product and a service.

The return/application history and underlying source records should tell one consistent story before any correction, payment or clarification is submitted.
Who should use this guide
This guide is for taxpayers facing the exact fact pattern in the title. It is especially useful when the portal and your books/documents do not agree, when another person handled the original filing, or when a current application/return deadline is approaching.
Why this problem usually happens
Founders confuse GSTIN with product-category registration and fear adding software consulting to a product business requires another tax number.
What should be checked immediately
Do not start with a correction entry. First collect the minimum evidence needed to prove what actually happened.
| Fact | Result |
|---|---|
| Goods + services, same entity/state | Can generally use same GSTIN |
| Different State branch | Separate State GSTIN may be needed |
| Different PAN/entity | Separate registration |
| Different activities | Different classification/rates still apply |
What to do now
List each revenue stream, HSN/SAC, place of supply, location and invoice type. Amend registration details where needed and set accounting/tax codes per activity.
Before submission, the client should receive a concise summary of the problem, the proposed tax/ITC/registration treatment, payment impact and any unresolved item. After submission, keep the ARN/order/acknowledgement and filed copy.
The 2026 legal and portal position
GST registration application includes both goods/HSN and services/SAC details and allows multiple entries.
GST Portal workflows, notifications and due-date extensions can change. The official sources below were checked for this article on 19 August 2026; recheck them immediately before filing if the matter is time-sensitive.
A realistic hypothetical
A Kerala company sells apparel and also provides software implementation. One Kerala GSTIN can generally report both, while each supply uses its own classification/rate/place-of-supply analysis.
What happens if the problem is ignored
Using one generic tax rate or wrong supply classification creates liability and customer issues.
What TargoLegal checks before filing or responding
TargoLegal checks supply categories, State registrations, HSN/SAC and accounting setup before amendment/filing.
Before filing
Documents received, missing items, reconciliation difference, legal/portal route, payment impact and client approval.
After filing
Filed copy, ARN/acknowledgement, payment proof and a short open-items list for the next period.
What to send for a first review
Selling goods and services together? Send the activities and State(s).
Related questions
What should I send first?
Send the GSTIN/ARN, the exact period or application stage, and the document that shows the problem. For this topic, the most useful starting point is: Legal entity/PAN, GSTIN/State, Goods categories.
Can I fix this by making an adjustment in the next return?
Not automatically. A later adjustment is appropriate only when the GST law and current portal workflow allow it and the original error has been reconciled.
Should I rely only on what the GST Portal auto-populates?
No. Portal data is essential evidence, but the taxpayer remains responsible for reconciling it with books, invoices and the applicable legal conditions.
What should I keep after the correction or filing?
Keep the filed return/form, ARN or acknowledgement, payment evidence, reconciliation working and any supplier/customer correspondence that explains the change.
When should professional review be considered?
Use professional review where the issue affects material tax or ITC, several periods, a registration notice, refund, e-invoicing, cancellation/revocation or a customer’s credit.
