GST Portal Multi-State Registration from 1 October 2026: what changed

The GST Common Portal introduced a Multi-State Registration facility from 1 October 2026. It is designed for normal taxpayers under the same PAN who need to start registration applications in more than one State or Union territory. The facility reduces repeated data entry by using a common starting workflow and a Master Temporary Reference Number (Master TRN). GST Portal — Multi-State Registration

The change is procedural, not a single nationwide registration. It does not create one GSTIN for all of India and does not remove State-wise legal requirements.

1. Open the Multi-State Registration option on the GST Portal.
2. Enter the PAN-based applicant details and select the States/UTs for which registration applications are required.
3. The portal generates a Master TRN for the multi-state workflow.
4. Use the Master TRN to enter the common registration information once, including the business, promoter/partner, authorised-signatory, authorised-representative and goods/services details requested by the portal.
5. After common information is submitted, the process creates separate State/UT application flows and State-wise TRNs.
6. Complete the State-specific information and supporting documents for each application.
7. Each application is processed separately and, if approved, results in a separate State/UT GSTIN.

The exact fields, authentication steps and supporting-document requirements shown by the live portal should be followed. Do not rely on screenshots or third-party summaries if the current portal differs.

• It does not decide whether the applicant is legally liable to register in a selected State/UT.
• It does not merge the resulting registrations into one GSTIN.
• It does not create one combined return, electronic ledger or notice record for all States.
• It does not remove State-specific scrutiny, place-of-business evidence or jurisdictional processing.
• It does not cancel the distinct-person treatment of separate registrations under the same PAN.

Section 25 of the CGST Act continues to require registration in every State or Union territory where the person is liable, and separate registrations under the same PAN continue to be treated as distinct persons. CBIC — CGST Act, section 25

• Legal name, PAN, constitution and contact details.
• Promoter, partner, director and authorised-signatory information.
• State-by-State principal and additional place-of-business details.
• Nature of possession and supporting address documents for each State/UT.
• Goods and services classifications requested by the portal.
• State-specific bank, jurisdiction, professional-tax or other particulars where applicable.
• A written liability analysis explaining why registration is required or sought in every selected jurisdiction.

• Maintain a registration master for every GSTIN, State, effective date and authorised signatory.
• Keep invoice series, returns, ledgers, notices and reconciliations identifiable by GSTIN.
• Document supplies between distinct persons under the same PAN.
• Review common input-service distribution or cross-charge treatment using current law and the actual facts.
• Do not assume that input-tax credit can be freely cross-used between separate GSTINs.
