The Central Government has notified significant amendments to the Central Goods and Services Tax (CGST) Rules, 2017, through Notification No. 05/2026–Central Tax dated October 26, 2026. Separately, Notification No. 04/2026–Central Tax expands the specified categories of transactions covered by the e-invoicing framework from January 1, 2027.
The amendments introduce a new registration option for eligible e-commerce sellers, revise procedures for GST registration amendments and cancellation, and provide for changes in the e-invoice schema. These measures are relevant for businesses, GST practitioners, tax professionals and e-commerce sellers preparing for upcoming compliance requirements.

1. E-Invoicing Scope Expanded from January 1, 2027
Notification No. 04/2026–Central Tax amends Notification No. 13/2020–Central Tax dated March 21, 2020, under Rule 48(4) of the CGST Rules, 2017.
The amended provision specifically covers the following categories:
- Supply of goods or services or both to a registered person.
- Supply of goods or services or both for exports.
- Supplies received from an unregistered person where the recipient is liable to pay tax under the reverse charge mechanism (RCM).
- Import of services.
The amendment expressly brings domestic supplies received from unregistered persons under reverse charge and imports of services within the specified categories.
The notification will come into force on January 1, 2027.
Businesses should review their invoicing systems, transaction classifications and compliance processes ahead of the effective date. The actual applicability of e-invoicing to a particular taxpayer must also be assessed against the relevant eligibility conditions and exemptions.
2. New GST Registration Option for E-Commerce Sellers
One of the key changes under Notification No. 05/2026–Central Tax is the insertion of Rule 14B into the CGST Rules, 2017, effective November 1, 2026.
The new rule provides an option for eligible suppliers selling goods through electronic commerce operators required to collect tax at source under Section 52 of the CGST Act.
Under this mechanism, a person registered in one State or Union Territory may obtain registration in another State or Union Territory where the person has no physical presence by declaring an eligible e-commerce operator's warehouse as the principal place of business.
The key conditions include:
- The supplier intends to sell goods through an eligible electronic commerce operator.
- The specified monthly output tax liability on supplies to registered persons, subject to the rule's conditions, must not exceed ₹2.5 lakh.
- The e-commerce operator must consent to the declaration of its warehouse as the principal place of business.
The application must be filed in Form GST REG-01. The process also includes prescribed authentication, document verification and physical verification requirements.
The e-commerce operator may communicate its consent within seven working days. If consent is not received within the prescribed period, the application will not be processed further.
This provision offers an additional registration route for qualifying sellers seeking to operate through e-commerce platforms in States where they do not have a physical establishment. Eligibility and procedural requirements must be checked before applying.
3. GST Registration Amendment Procedure Revised
The notification substitutes Rule 19, which governs amendments to GST registration particulars.
Under the revised provision, an application in Form GST REG-14 is generally required within 15 days of a change in the relevant particulars, along with supporting documents.
For changes involving specified principal place of business details, the application is subject to scrutiny by the proper officer. Where the application and documents are in order, the officer is required to approve the application within the prescribed period.
The amended procedure also provides for:
- A notice seeking clarification or additional documents, where required.
- A prescribed period for the applicant to respond.
- Rejection where deficiencies remain unresolved or a required response is not furnished.
- Deemed approval in specified circumstances where the proper officer does not act within the prescribed timeline.
The notification also specifies separate commencement provisions for certain amendments. Taxpayers should therefore identify the effective date applicable to the particular change rather than assuming that every amendment takes effect on the same day.
4. Revised Rules for Cancellation of GST Registration
The amended Rule 20, effective November 1, 2026, revises the procedure for taxpayers seeking voluntary cancellation of GST registration.
An application in Form GST REG-16 is generally required within 30 days of the event necessitating cancellation. The application must include relevant details of stock, inputs contained in semi-finished or finished goods, capital goods and associated liabilities, as applicable.
The revised rule also links the cancellation process with return filing and payment compliance. Relevant pending returns must be furnished, and applicable tax, interest, fees, penalties or other amounts must be paid.
Depending on the circumstances and fulfilment of prescribed conditions, cancellation may be processed electronically through the common portal or referred to the proper officer for examination.
The amendment also provides timelines for scrutiny, responses to notices and orders concerning cancellation. Taxpayers should review their outstanding returns and liabilities before submitting a cancellation application.
5. Changes Relating to Suspension and Cancellation for Non-Compliance
The notification revises provisions dealing with suspension and cancellation of GST registration in specified cases of non-compliance.
The amended framework addresses situations involving prolonged non-filing of returns and non-compliance with prescribed bank-account-related requirements.
Under the provisions scheduled to take effect from April 1, 2027, specified cases may result in suspension of registration, with a notice requiring the taxpayer to furnish pending returns or comply with the applicable requirement within the prescribed period.
The rules also provide for cancellation in specified circumstances if the taxpayer does not address the identified non-compliance within the applicable timeline.
Businesses should monitor GST portal notices, maintain valid registration particulars and ensure timely filing of returns to reduce the risk of disruption to taxable operations.
6. E-Invoice Schema to Be Updated to Version 1.2
Notification No. 05/2026–Central Tax also provides for an update to Form GST INV-01 from January 1, 2027.
The e-invoice schema reference will change from Version 1.1 to Version 1.2. The revised supply-type codes include:
- B2B – Business to Business
- B2C – Business to Consumer
- SEZWP and SEZWOP – Supplies to Special Economic Zones with or without payment
- EXPWP and EXPWOP – Exports with or without payment
- DEXP – Deemed exports
- SEZWPA and SEZWPNA – Supplies to SEZs with payment for authorised and non-authorised operations
- RCMDOM – Domestic supplies from unregistered persons under RCM
- RCMIMP – Import of services
The addition of RCMDOM and RCMIMP provides specific supply-type identifiers for domestic reverse charge transactions involving unregistered suppliers and imports of services.
Businesses and software providers should review the updated schema and assess whether their invoicing and accounting systems require changes before implementation.
7. Effective Dates: What Businesses Should Know
The amendments have different commencement dates, making it important for taxpayers to plan their compliance activities accordingly.
| Effective date | Key change |
|---|---|
| November 1, 2026 | CGST Amendment Rules, 2026 generally come into force; new Rule 14B and revised cancellation provisions become applicable. |
| December 1, 2026 | A specified amendment concerning Rule 19(3) takes effect. |
| January 1, 2027 | Notification No. 04/2026–Central Tax takes effect; e-invoice schema Version 1.2 and related supply-type code changes apply. |
| April 1, 2027 | Specified amendments relating to registration suspension and cancellation procedures, along with related provisions and forms, take effect. |
Conclusion
The October 26, 2026 notifications introduce important changes to GST invoicing and registration compliance. The expanded specified scope of e-invoicing, the new Rule 14B registration option for eligible e-commerce sellers, and revised registration amendment and cancellation procedures require businesses to review their existing processes.
Taxpayers should identify the provisions applicable to their operations, note the relevant commencement dates and coordinate with their accounting and technology teams to prepare for the changes.
