Revised GST REG-01 From 1 November 2026: 9 Changes in the GST Registration Form and How to Apply Without Rejection

GST | RegisCorp Team

Short answer: GSTN has revised FORM GST REG-01, the application for new GST registration, to match Notification No. 05/2026-Central Tax and Circular No. 257/03/2026-GST (both dated 26 October 2026). The headline changes are: One Person Company (OPC) is now its own constitution category; SEZ applicants must give an SEZ Entity ID; e-commerce operators under Section 9(5) get a separate section; existing registrations (GSTIN, Professional Tax numbers) must be disclosed; premises are classified into standard categories with matching documents; the business-activity list is longer; up to 10 bank accounts can be reported; LLP applicants must give the DIN of each designated partner; and CIN, LLPIN, FCRN and FLLPIN are validated online before an ARN is generated. Prepare documents to match the category you choose, because a mismatch is now the quickest route to a REG-03 notice.

How to read this post. The nine changes below are as reported from the GSTN advisory dated 1 November 2026 and trade-press summaries of the notification and circular. We could not open the advisory page directly, so we have not copied any wording from it. Read the notification, the circular and the live form on the GST portal before you file. This is general information, not tax advice.

What changed and why it matters

A GST registration application is usually decided on documents, not on the form itself. Officers raise a notice in FORM GST REG-03 when a document does not match what the applicant declared. The revised form is built around that problem: it asks for more structured information up front, validates identity numbers online, and ties each premises category to a specific document. That helps a clean application move faster and makes a careless one fail earlier.

The nine changes

1. OPC is a separate constitution category. A One Person Company no longer needs to be squeezed into "Company" or "Others". Upload documents that match the constitution you select, such as the certificate of incorporation, partnership deed or registration certificate, as applicable.

2. SEZ Entity ID. If you are applying as an SEZ Unit or SEZ Developer, a new field asks for your SEZ Entity ID. Keep the approval or letter of approval handy.

3. A separate section for e-commerce operators under Section 9(5). Applicants in this category must give details of their physical presence in the State or Union Territory and, where applicable, their authorised representative.

4. Existing registrations must be disclosed. The form now asks for your existing GSTIN, Professional Tax Registration Number and Professional Tax Enrolment Registration Number, along with other particulars. If you already run a business elsewhere in the same PAN, fill this part carefully.

5. Standard premises categories. Possession of the principal place of business and additional places of business is classified as: owned; premises in the name of a deceased ancestor; rented or leased; consent-based; co-working space; and SEZ premises. Each category has its own supporting documents, which are set out in Circular 257/03/2026-GST. Pick the category that is true, not the one that looks easiest.

6. A longer list of business activities. Additions reported include factory registration particulars, Authorised Economic Operator details, co-working space, health and fitness clubs, renting or leasing of immovable property, and renting or hiring of motor vehicles, vessels or aircraft. The list is open-ended, so check the live dropdown.

7. Up to 10 bank accounts. You can report up to ten accounts. If you do not have account details at the time of application, they must be furnished within 30 days from the date of issue of the registration certificate in FORM GST REG-06. The clock runs from REG-06, not from filing.

8. DIN of every LLP designated partner. LLP applicants must furnish the Director Identification Number of each designated partner. Check that each DIN is active and matches the name on the LLP records.

9. Online validation of CIN, LLPIN, FCRN and FLLPIN. Where applicable, these numbers are validated online and, as reported, the ARN is generated only after successful validation. A typo here can stop you before you even receive an acknowledgement.

Trade-press summaries of the same notification also report a substituted Rule 19 for amendments and a new Rule 14B that lets a registered supplier of goods use an e-commerce operator's warehouse in another State as a principal place of business, subject to a monthly output-tax limit. They also report that the faster online validation of principal-place-of-business amendments for some Rule 14A taxpayers starts later, on 1 December 2026. These details come from secondary sources only. Treat them as leads and confirm them in the notification before relying on them.

Common mistakes to avoid

Frequently asked questions

Does this apply to my existing registration? The revised form is for new applications. Changes to an existing registration go through the amendment route, and the amendment rules are reported to have changed too. See our guide on GST registration amendment.

Do I need to file anything differently if I only sell on an e-commerce platform? Sellers who supply through an operator still apply for their own registration unless exempt. The new section on Section 9(5) is for the operators themselves.

What if my application gets a REG-03 notice? Reply in FORM GST REG-04 with the correct documents within the time allowed on the notice. Reported timelines are around seven working days. Read the notice carefully and answer each point.

Is a co-working address acceptable? It now has its own category. Attach the co-working agreement and any proof the circular asks for.

Can I cancel and re-apply if I selected the wrong category? If registration has not been granted, you can respond to the notice with corrected details. After grant, use the amendment route or consult your adviser. If the registration is not needed, see GST cancellation.
