On 1 October 2026, GSTN introduced a "Multistate Registration" facility on the GST portal. A business that needs GST registration in more than one State or Union Territory under the same PAN can now enter its common details once and use them for every State it applies in.
The facility saves typing, not compliance. Each State still needs its own application, its own place-of-business details and its own Aadhaar authentication, and each State registration remains separate.
At a Glance
| Point | Position |
|---|---|
| What's new | A "Multistate Registration" tab on the GST portal homepage to apply in several States/UTs together |
| Announced | GSTN advisory dated 1 October 2026 |
| Who can use it | Normal taxpayers only, for now |
| Key feature | Common details entered once (Common Registration Information), auto-filled into each State's application |
| Time limit | Master TRN must be submitted within 15 days |
| Still required per State | Principal and additional places of business, State-specific information, Aadhaar authentication |
| Legal change | None — this is a portal facility; registration remains State-wise |
How the Facility Works
The applicant fills the common part once, and the portal then opens a separate application for every State selected.
- Select the States/UTs. Use the new "Multistate Registration" tab on the GST portal homepage and choose every State/UT where registration is needed.
- Get a Master TRN. The portal generates one Master Temporary Reference Number covering the selected States.
- Submit the Common Registration Information (CRI) once. Using the Master TRN, enter details that are the same for every State: business details, promoters or partners, authorised signatory, authorised representative, and goods and services. The Master TRN must be submitted within 15 days.
- Receive individual TRNs. After the CRI is submitted, the portal generates a separate TRN for each selected State/UT. The common details are auto-filled in each and can still be edited.
- Complete each State's application. In each TRN, add the Principal Place of Business, any Additional Places of Business, State-specific information, and complete Aadhaar authentication.
In GSTN's words, the facility "reduces repetitive data entry and facilitates ease of doing business."
What Has Not Changed
The new tab changes how you apply, not what the law requires. GST registration remains State-wise.
- Registration in every State where you are liable. Section 25(1) of the CGST Act requires a person to register in each State or Union Territory in which they are liable to registration. Applying through one Master TRN does not create a single "national" registration.
- One GSTIN per State. Each completed application results in its own registration in that State. Under section 25(4), each such registration is treated as a distinct person.
- Each application is verified on its own. Each State's application still has its own TRN, its own place-of-business details and its own Aadhaar authentication, and is processed for that State.
- Ongoing compliance stays per GSTIN. Returns, invoices and records are maintained separately for each registration. Supplies between your own registrations in different States can be taxable, since Schedule I of the CGST Act treats supplies between distinct persons as supplies even without consideration.
- Other taxpayer types. The facility is currently open only to normal taxpayers. Casual taxable persons, non-resident taxable persons, TDS/TCS deductors and other special categories should continue to apply through their regular routes.
Who Benefits, and Practical Tips
The facility is most useful for a business opening in two or more States at the same time, for example:
- a company setting up branches or warehouses in several States;
- an e-commerce seller adding fulfilment-centre locations in other States;
- a contractor starting projects in a new State alongside its home State;
- a new business that will operate from more than one State from day one.
Practical tips
- Finalise the common details before you start. Promoter details, authorised signatory, and goods and services codes flow into every State, so an error in the CRI repeats across all applications.
- Watch the 15-day window. The Master TRN must be submitted within 15 days. Keep documents for all States ready before generating it.
- Collect State-specific documents in advance. Each State needs proof of its own place of business (rent agreement or ownership proof, consent letter, utility bill) and its own Aadhaar authentication.
- Review the auto-filled data in each TRN. The details are editable, so confirm what applies to each State, such as the goods or services dealt in there.
- Plan for separate compliance. Each new GSTIN brings its own returns and, where applicable, e-invoicing and e-way bill obligations from its effective date of registration.
Common mistakes to avoid
- Assuming one application means one GSTIN for all States.
- Using the facility when registration is needed in only one additional State — the regular route works just as well.
- Forgetting that Aadhaar authentication is required separately in each State's TRN.
Frequently Asked Questions
What is GST Multistate Registration? A facility on the GST portal, announced by GSTN on 1 October 2026, that lets a business apply for GST registration in several States/UTs together under the same PAN, entering common details only once.
Will I get one GSTIN for all States? No. GST registration remains State-wise. You get a separate registration, and a separate GSTIN, for each State, and each is treated as a distinct person.
Who can use the facility? For now, only normal taxpayers. Other categories continue to use the regular registration routes.
What is a Master TRN? The single Temporary Reference Number generated when you select multiple States. You use it to submit the Common Registration Information, and it must be submitted within 15 days.
What is Common Registration Information (CRI)? Details that are the same across States: business details, promoter or partner details, authorised signatory, authorised representative, and goods and services.
What do I still fill separately for each State? The Principal Place of Business, any Additional Places of Business, State-specific information, and Aadhaar authentication.
Is the multistate route compulsory? No. It is an optional facility. You can still apply State by State through the regular registration form.
Conclusion
The Multistate Registration facility is a welcome ease-of-doing-business step for growing businesses. It cuts the repeated data entry of applying State by State, but every State registration is still separate, still needs its own place-of-business proof and Aadhaar authentication, and brings its own GST compliance.
