Overview: The GST registration process has changed from 1st November, 2026. The revised FORM GST REG-01 introduces more specific business and premises details, while the Central Board of Indirect Taxes and Customs (CBIC) has issued a document checklist and instructions for applicants. A substituted Rule 19 also changes how existing registration particulars are amended. Most amendments can now be completed through online validation, although specified changes to the principal place of business continue to require examination by the proper officer.
The GST registration process has undergone key changes From 1st November, 2026. A revised application form, clearer document requirements and changes to the amendment procedure are intended to make registration and subsequent updates more straightforward. The revised framework also sets out which changes can be validated online and which still require scrutiny by the proper officer.
A Goods and Service Tax (GST) registration application can face delays because of incomplete business details, unsuitable premises documents or information that does not match the applicant’s legal records. The latest changes seek to address these problems through a revised application form, clearer document requirements and a more streamlined amendment process.
The changes were notified through Notification No. 05/2026–Central Tax dated 26 October 2026, which introduced the Central Goods and Services Tax (Amendment) Rules, 2026. Most of the amendments came into force on 1st November, 2026. The Central Board of Indirect Taxes and Customs (CBIC) also issued Circular No. 257/03/2026-GST dated 26th October 2026, containing instructions and a detailed checklist for applicants seeking GST registration.
The changes matter to both new applicants and existing registered businesses. They affect the information submitted on the GST portal, the documents required to establish a place of business and the procedure for updating registration particulars.
Revised FORM GST REG-01: What has changed?
FORM GST REG-01 remains the principal application form for a new GST registration in the ordinary course. Its revised version provides more structured fields and document options.
Some important changes include:
- One Person Company: OPC is now expressly listed as a separate business constitution category. Applicants must select the correct constitution and provide the corresponding proof, such as the Certificate of Incorporation.
- SEZ particulars: An applicant seeking registration as a Special Economic Zone (SEZ) unit or developer must provide the relevant approval details, including the SEZ Entity ID, approval order number and date, validity period and designation of the approving authority.
- E-commerce operators: The form separately asks whether the applicant is an e-commerce operator liable to pay tax under Section 9(5) of the CGST Act, 2017. Where applicable, the applicant must provide the required particulars, including details of the representative responsible for paying tax where the operator has no physical presence in the State or Union Territory.
- Existing registrations: The revised form captures details of relevant existing registrations, including GSTIN, Professional Tax registration, CIN, LLPIN, IEC and Shops and Establishment registration, wherever applicable.
- Premises details: Applicants must select the correct nature of possession of the principal place of business. The categories include owned, premises in the name of a deceased ancestor, rented or leased, consent-based, co-working space and SEZ premises. A separate option is available for an e-commerce operator’s warehouse under Rule 14B.
- Business activities: The form provides more specific options for describing the nature of business conducted at the premises. Applicants must select activities that accurately reflect their operations.
- Promoters and authorised signatories: The form requires details and photographs of the relevant persons. It allows details of up to ten authorised signatories, including the primary authorised signatory. An authorisation letter must support the appointment of each authorised signatory.
The revised form also provides for online validation of relevant PAN, Aadhaar, DIN, CIN, FCRN, LLPIN and FLLPIN particulars. The Application Reference Number (ARN) is generated after successful validation of the required information and completion of the applicable authentication process.
New Rule 14B: Registration through an e-commerce operator’s warehouse
The amended rules introduce Rule 14B for certain suppliers of goods using an e-commerce operator’s warehouse in a State or Union Territory where they do not have a physical presence.
A person already registered under Rule 9 in a State or Union Territory where the person has a physical presence may apply for registration against the same PAN in another State or Union Territory by declaring a warehouse of an e-commerce operator as the principal place of business. The e-commerce operator must be one required to collect tax at source under Section 52 of the CGST Act, 2017.
The applicant must intend to supply goods through that operator, obtain the operator’s consent to use its warehouse as the principal place of business and satisfy the prescribed output tax liability condition. The combined output tax liability on supplies to registered persons other than persons registered under the same PAN must not exceed ₹2.5 lakh per month.
The application is made through FORM GST REG-01. The process includes the e-commerce operator’s consent, biometric-based Aadhaar authentication and document verification where required, and physical verification of the applicant’s principal place of business in the home State where the prescribed process has not already been completed.
This facility is distinct from the simplified registration scheme under Rule 14A. Rule 14B concerns eligible suppliers of goods using an e-commerce operator’s warehouse in another State or Union Territory; The ₹2.5 lakh monthly threshold applies specifically to output tax liability on designated supplies made to registered entities. Rule 14A is a separate scheme for eligible small taxpayers.
GST registration: How to file the revised e-application
The registration application is filed online through the GST common portal. For an ordinary registration, the applicant must use FORM GST REG-01.
Step 1: Start the application and complete Part A
On the GST portal, select Services, then Registration, and New Registration. Enter the PAN, legal name, State and district of the principal place of business. The legal name must match the PAN records and, for an incorporated company, the incorporation certificate. In a proprietorship, the proprietor’s name is entered as the legal name.
The applicant must verify the mobile number and email address through separate OTPs. After successful verification, the portal generates a Temporary Reference Number (TRN).
Step 2: Complete Part B
Use the TRN to access Part B of FORM GST REG-01. Enter the business constitution, reason for registration, details of promoters or partners, authorised signatories, principal and additional places of business, nature of activities and other applicable particulars.
Applicants should take care when selecting the State and Centre jurisdiction. The principal place of business address must be complete and specific, including the building, flat, shop or premises number, locality, district and PIN code.
Step 3: Upload the supporting documents
Upload the documents relevant to the selected business constitution and premises category. The name and address in the documents should match the particulars entered in the application. Photographs must be recent, clear individual photographs of the relevant persons; group photographs or photographs copied from identity documents are not acceptable.
Step 4: Complete authentication and submit
The application must be digitally signed or verified through the permitted electronic method, as applicable to the applicant. Aadhaar authentication may be required. Some applications are selected for biometric-based Aadhaar authentication, photograph capture and verification of original documents at a designated facilitation centre. Where the applicant receives such an intimation, the prescribed process must be completed within 15 days from receipt of the TRN.
Additionally, site visits to conduct physical premises verification may be required under specific conditions specified by the rules.The application is not treated as complete in cases requiring biometric authentication and document verification until that process has been completed successfully.
After successful submission and completion of the applicable validation and authentication requirements, the portal issues an acknowledgement in FORM GST REG-02. Once registration is approved, the registration certificate is made available electronically in FORM GST REG-06.
The application process is online and faceless, but that does not remove the requirement to visit a facilitation centre or cooperate with physical verification where the rules require it.
Premises documents: The category must be correct
CBIC Circular No. 257/03/2026-GST gives specific guidance on the documents required for different types of premises. This is important because an applicant must not select a premises category merely because a particular document is available.
For an owned premises, the applicant may submit one of the prescribed ownership-related documents, such as a recent property tax receipt, municipal khata, property identification document or latest electricity or water bill. The premises will be treated as owned by the applicant where the applicant himself or herself is the owner.
If the property belongs to a parent, spouse, sibling, partner or director, it cannot automatically be declared as the applicant’s own premises. The appropriate consent, rented, leased or shared category must be selected, depending on the arrangement.
Where the premises are owned by a deceased ancestor and no ownership document is available in the applicant’s name, the applicant must upload the prescribed affidavit, a copy of the ancestor’s death certificate and one of the accepted property or address documents in the name of the deceased ancestor or the applicant.
For rented or leased premises, the documents depend on the agreement and the applicable registration requirement. Where a registered rent or lease agreement is available, a clear and legible copy of the valid registered agreement must be uploaded.
If the lease or rental agreement does not legally require registration, the applicant must submit a copy of the agreement accompanied by a valid proof of address or ownership in the lessor’s or landlord’s name. Alternatively, if the utility connections (such as water or electricity) are registered directly under the tenant’s name, providing the most recent utility bill alongside the valid rent agreement satisfies the documentation requirement without needing the lessor’s ownership proof.
Where no rent or lease agreement is available, the applicant must upload the prescribed undertaking and proof of possession, such as a latest electricity or water bill in the tenant’s name showing the complete premises address.
For consent-based premises, the applicant must upload the prescribed consent letter from the owner and one of the accepted ownership or address documents in the owner’s name. Where the premises are co-owned by more than one owner and are being provided on a consent basis, consent from all such co-owners is required.
For a co-working space, a membership agreement must identify the period of the agreement and the specific suite, cabin or desk allocated to the applicant. It must also state whether the co-working provider owns the premises or has taken them on rent or lease. Where the provider owns the premises, the prescribed ownership proof in its name must be uploaded. Where the provider has taken the premises on rent or lease, the applicant must also upload a copy of the valid registered rent or lease agreement between the provider and the property owner.
An SEZ applicant must provide a clear and legible copy of the valid Letter of Approval or Letter of Permission issued by the Development Commissioner of the SEZ.
The circular also makes clear that an Udyam certificate is not a mandatory GST registration document. Officers should not raise irrelevant queries merely because the applicant’s residential address is in a different city or State, or because the declared business premises are residential. The purpose of the document check is to establish the applicant’s identity, the constitution of the business and the right to use the declared premises.
The same documentary requirements apply when amending the details of the principal or an additional place of business.
Registration applications timeline
The circular also explains the processing timelines and the circumstances in which an officer may seek clarification.
Where the applicant opts for Aadhaar authentication and successfully completes it, the “proper officer” is required to process the application within seven working days from the date of submission.
A 30-day processing period applies where the applicant does not opt for Aadhaar authentication or fails to complete it, where the application is identified for physical verification through the common portal’s data analysis and risk parameters, or where the proper officer considers physical verification necessary after obtaining the prescribed approval. In these cases, the application is processed after the physical verification required under the rules.
There are also separate system-based routes. Eligible applicants under Rule 14A and applicants identified for electronic grant of registration under Rule 9A may receive registration automatically within three working days, subject to the conditions of the relevant provisions.
If the application contains incomplete, contradictory or illegible information, the “proper officer” may issue a notice in FORM GST REG-03. Where the application has not been identified for physical verification, the notice may be issued within seven working days from the date of submission. Where physical verification has been identified by the system, or the officer considers it necessary after obtaining the prescribed approval, the notice may be issued within 30 days.
The notice should identify the deficiency. The applicant must submit the clarification, information or documents electronically in FORM GST REG-04 within seven working days of receiving the notice.
The officer must then decide the application within seven working days of receiving the reply. If the reply is satisfactory, the officer must approve the application within that period. If the officer is not satisfied, the application may be rejected through FORM GST REG-05, with reasons recorded in writing. The rules also provide for deemed approval where the officer does not act within the applicable time.
The circular instructs officers not to seek documents that are not part of the prescribed requirements or raise presumptive objections about the suitability of residential premises. To avoid processing delays or rejection, applicants must verify that all submitted documentation and details are legible, consistent, and fully accurate.
GST registration amendments: Revised Rule 19 and FORM GST REG-14
The substituted Rule 19 of the CGST Rules, 2017 changes the procedure for amending existing registration particulars. A registered person must generally submit an application in FORM GST REG-14 within 15 days of the change, along with the documents relating to that change.
The procedure depends on the nature of the amendment.
1. Change in the principal place of business
For an ordinary registered taxpayer, an amendment relating to the principal place of business is forwarded to the “proper officer” for examination. If the application and documents are in order, the officer must approve it within 15 days from the date of submission and issue an electronic order in FORM GST REG-15.
If clarification or further documents are required, the officer may issue FORM GST REG-03 within 15 days of the application. The taxpayer must reply through FORM GST REG-04 within seven working days of receiving the notice. If the reply is satisfactory, the officer must approve the amendment within seven working days of receiving it.
If the officer is not satisfied, the application may be rejected through FORM GST REG-05, with reasons recorded in writing. If the taxpayer fails to respond within the given timeframe, the application will be deemed rejected, and notification will be issued via FORM GST REG-05A.
The rule also provides for deemed amendment if the proper officer fails to act within the prescribed period: 15 days from the application, or seven working days from receipt of the taxpayer’s clarification, as applicable.
2. Other changes in registration particulars
For changes other than those relating to the principal place of business, the certificate of registration stands amended after the application is submitted and the required online validation is completed. The amended certificate is then made available to the registered person on the GST portal, wherever applicable.
Consequently, updates to information like legal name, business constitution, and additional places of business typically undergo automated online validation, bypassing the standard officer-approval workflow required for updates to the principal place of business.
The revised FORM GST REG-14 requires online verification of the mobile number and email address of the primary authorised signatory and one selected promoter, partner, director, Karta, member or trustee, as applicable. For specified other registration forms, verification of the authorised signatory is required. For GST Practitioner enrolment, the practitioner must complete the prescribed verification.
The applicant has three days from submission to complete the required OTP verification. If authentication is not completed successfully within that period, the ARN will not be generated. PAN, DIN and CIN particulars are also subject to online validation. Applicants are not required to pay any government fee when submitting an application for registration amendment.
3. Changes affecting registrations under the same PAN
When updating key registration details – such as the business’s legal name or the composition of individuals managing daily operations (including partners, directors, Karta, managing committee members, trustees, or the CEO) – the modification automatically extends across every GST registration associated with that PAN.
If a corporate restructuring requires obtaining a new PAN, such a modification cannot be processed via a standard amendment. In such cases, the business entity is required to submit an application for a fresh GST registration.
4. Special provision for Rule 14A taxpayers
A separate provision applies to taxpayers registered under Rule 14A who have not opted to withdraw from that scheme. Under substituted Rule 19(3), an amendment to their principal place of business is accepted through online validation rather than the ordinary officer-approval route.
This provision comes into force on 1st December, 2026. Until then, the general officer-approval requirement for a change in the principal place of business continues to apply.
What businesses should do
New applicants should review the revised FORM GST REG-01, confirm the legal name and business constitution, and collect the correct premises documents before starting the application. They should also ensure that the authorised signatory and relevant promoters or partners are available for OTP verification and any Aadhaar or biometric process.
Existing taxpayers should report changes within 15 days, use FORM GST REG-14 and complete the prescribed verification within three days wherever it applies.
A change of principal place of business should be supported by the relevant premises documents and tracked through the officer-approval process. Changes to additional places of business and other registration particulars should also be reported within the prescribed period, even though they follow the online-validation route.
