GST PORTAL UPDATE | GSTN ADVISORY 674 | MULTI-STATE REGISTRATION

Advisory date: 1 October 2026   |   Facility: Multi-State Registration using a Master TRN

GSTN has introduced a new Multi-State Registration facility on the GST Portal for taxpayers who need GST registration in more than one State or Union Territory under the same PAN.

The new flow uses a Master Temporary Reference Number (Master TRN) so that common registration information can be entered once and then carried into separate State/UT registration applications. At present, the facility is available only for Normal Taxpayers.

What has changed? A taxpayer requiring GST registration in multiple States/UTs can now begin the process through one Multi-State Registration facility. A Master TRN is generated, common information is submitted once, and separate State/UT TRNs are then created for completing the remaining State-specific details.

GSTN states that the facility can be used by taxpayers seeking registration in more than one State/UT under the same PAN. Currently, the facility is available only for Normal Taxpayers.

The new Multi-State Registration tab is available from the GST Portal home page.

Using the Master TRN, the applicant can enter common information including:

• Business Details
• Promoter / Partner details
• Authorised Signatory
• Authorised Representative
• Goods and Services

Important: GSTN says the Master TRN must be submitted within 15 days.

After the CRI is submitted, individual TRNs are generated for each selected State/UT. The common information is auto-populated and remains editable. The applicant must then complete the remaining State-specific information, including:

• Principal Place of Business (PPoB)
• Additional Place of Business (APoB)
• State-specific information
• Aadhaar authentication

The key benefit is reduced repetitive data entry. Common details do not have to be entered separately for every State/UT registration application. The change simplifies the application workflow while still retaining the individual State/UT registration process.

The facility is available through the Multi-State Registration option on the GST Portal home page.
