The GST Portal has launched a 'Multi-State Registration' facility effective from October 1, 2026, allowing eligible businesses to apply for GST registration in multiple states or union territories through a single application flow. Common details such as business name and PAN are entered once, generating a Master Temporary Reference Number (Master TRN), which then creates state-specific TRNs, reducing repetitive data entry.

Separate GSTINs will still be issued for each state or union territory after individual applications are processed. The facility is currently available only for Normal Taxpayers. Applicants must submit the Master TRN within 15 days and carefully verify common information, as errors may lead to repeated corrections.
The new facility reduces paperwork for businesses operating in multiple states, but compliance remains state-specific. The Master TRN simplifies the initial application, not the ongoing filing. Users must still provide state-specific details like principal place of business and undergo Aadhaar authentication separately. The 15-day submission window for the Master TRN adds a new deadline that businesses must track.
