Last Updated on October 1, 2026
Latest update (1 October 2026): As of 1 October 2026, the GST Common Portal has introduced a “Multi-State Registration” option that allows applicants to initiate GST registration applications for multiple States/UTs through a common flow.
What is Multi-State GST Registration?
Multi-State GST Registration is a new GST Portal facility that lets you start GST registration applications for more than one State or Union Territory through one common flow. The portal issues one Master TRN, and after you submit it, it generates a separate TRN for each selected state. It simplifies how you apply. It does not give you a single all-India GSTIN.
GST Portal Live Multi-State Registration: What has changed?
Until now, GST registration in multiple states meant filing a separate application for each state. Each one began with its own details, OTP verification and TRN.
With the new facility:
- You select multiple States/UTs from a multi-select list.
- You enter the legal name (as per PAN and MCA records where applicable), PAN and email.
- You get one Master TRN for all your selected states.
- After you submit the Master TRN, the portal generates state-specific TRNs.
- The common profile details entered during the initial process are automatically populated into the respective State-specific applications.
Quick Summary
The GST Portal’s Multi-State Registration facility allows businesses to start GST registration applications for multiple States or Union Territories through one common flow, while each state still receives its own GSTIN.
- You can select multiple States or Union Territories during the GST registration process through the new Multi-State Registration option.
- The portal generates one Master TRN for the common application flow.
- After submission, a State-specific TRN is generated for each selected State or Union Territory.
- Each State continues to have a separate GSTIN; the facility does not create one GSTIN for all of India.
- The new process is designed to simplify multi-state GST registration by reducing the need to initiate each application separately.

What is a Master TRN and a state-specific TRN?
A Master TRN is the common Temporary Reference Number generated for all the States/UTs you select. A state-specific TRN is generated for each state after you submit the Master TRN, and you complete that state’s application with it. The Master TRN does not replace the individual state applications.
Is One GSTIN Issued for Multiple States?
No. This is one of the most important points businesses should understand about the new facility. The Multi-State Registration functionality does not mean that one GSTIN will cover all selected States. GST registration remains state/UT specific.
Therefore: One PAN + Multiple State registrations = Multiple GSTINs.
Example: A company has operations requiring registrations in Tamil Nadu, Karnataka and Kerala. The company may use the Multi-State Registration facility to initiate the applications together. Businesses managing several GSTINs can also check GST registration status by PAN number to view registrations associated with the same PAN. The result is not one company → one GSTIN for three States. Instead, the structure remains one company/PAN → Tamil Nadu GSTIN + Karnataka GSTIN + Kerala GSTIN.
Documents Required for Multi-State GST Registration
The common flow needs your PAN, legal name, email, mobile number and list of states.
- Constitution proof (incorporation certificate, partnership deed or LLP agreement)
- PAN and Aadhaar of promoters, partners or directors
- Address proof for the principal place of business in each selected state, plus a rent agreement and consent letter if the premises are rented
- Bank account proof
- Authorisation letter and photograph of the authorised signatory
- Digital Signature Certificate for companies and LLPs
Note: The exact document requirements may vary based on the taxpayer type and State-specific application details. Applicants should verify the requirements shown on the GST Portal before submission.
How to Apply for GST Registration in Multiple States: The New 2026 Process
Select Multi-State Registration → Enter common details → Verify with OTP → Get Master TRN → Submit Master TRN → Receive state-specific TRNs
- Open the option. It appears separately from the regular registration options on the GST Common Portal.
- Enter the common details. These are the legal name, PAN, email and mobile number.
- Select your States/UTs. For example, Tamil Nadu, Karnataka and Kerala.
- Complete OTP verification on the email and mobile number you entered.
- Receive your Master TRN.
- Submit the Master TRN to generate a state-specific TRN for each state.
- Complete each state application and track its status on the portal.
The portal currently allows only one registration per State/UT under one Master TRN.
Under the standard process, the GST Portal purges TRN data if the application is not submitted within 15 days, and the application stays in Draft until then (see the official GST registration manual). Confirm the validity period for a Master TRN on the portal before you start.
GST registration in Tamil Nadu, Karnataka and Kerala: an example
A Chennai company opening branches in Karnataka and Kerala selects all three states in one flow and receives one Master TRN. After submission, it gets three state-specific TRNs, then three GSTINs once each application is approved.
Old vs new: GST registration for multiple states
| Earlier process | New Multi-State process | |
| Starting applications | Separately for each state | Once, with all states selected |
| Common reference | None | One Master TRN |
| State-level references | One TRN per application | State-specific TRNs after Master TRN submission |
| Common details | Re-entered each time | Common profile carried into state applications |
| GSTINs | One per state | One per state (unchanged) |
| Documents and verification | Per state | Still required per state |
What Businesses Can Benefit From the New Facility?
The Multi-State GST Registration facility is useful for businesses expanding or operating across multiple States/UTs. It allows eligible taxpayers to initiate multiple State-wise GST registration applications through a common flow, reducing repetitive initial data entry.
It can be useful for:
- Companies and startups expanding into multiple States
- Manufacturers and distributors with plants, warehouses or branches
- Retail businesses operating outlets across different States
- MSMEs expanding their operations beyond their home State
However, having customers in another State does not automatically mean a separate GST registration is required. The requirement depends on the business’s applicable GST position and activities.
Checklist Before You Apply
- Confirm in which states you actually need registration.
- Match your PAN and legal name exactly.
- Keep state-wise addresses and premises documents ready.
- Remember that a TRN is not approval.
- Review every state application before submitting.
- Watch for GSTN or CBIC advisories.
GST Compliance After Multi-State Registration
Each GSTIN has its own obligations, including separate GST return filing (GSTR-1 and GSTR-3B), tax payment, invoicing and records. Plan a compliance calendar per state. Your income tax return filing is separate and stays PAN-level.
Conclusion
The Multi-State Registration facility on the GST Portal is a significant change to the way businesses can initiate GST registration applications for multiple States and Union Territories. The facility allows applicants to select multiple jurisdictions, generate a Master TRN and subsequently obtain separate State-specific TRNs.
The most important point is that the facility does not create a single GST registration for multiple States. Individual State/UT registrations and GSTINs continue to remain relevant.
Since the functionality is newly visible on the portal as of 1 October 2026, businesses should also watch for detailed official GSTN/CBIC instructions before relying on any assumptions about eligibility, documentation or the complete procedure.
