Date from which the amendment option was available on portal

The "amendment option" on the GST portal refers to different functionalities depending on whether you are referring to Registration details or Return filings (such as GSTR-1 or GSTR-1A).

1. Amendment of Registration Details

The facility to amend registration details (Core and Non-Core fields) has been available on the GST portal since the inception of the GST regime in July 2017.

• Core Fields: Require approval from a GST officer (e.g., changes to the business name, address, or partners/directors).

• Non-Core Fields: Updated automatically upon submission without officer approval (e.g., contact details or email IDs).

• Rule: Amendments must generally be filed in Form GST REG-14 within 15 days of the change.

2. Amendment of GST Returns (GSTR-1)

Taxpayers have been able to amend B2B invoice details and other records in GSTR-1 since the early stages of the GST rollout.

• Standard Amendment: Corrections to invoices from previous periods are typically handled in the GSTR-1 of a subsequent month/quarter. This has been a core feature of the portal since the beginning.

• GSTR-1A (The "Newer" Amendment Facility): A more recent functionality is Form GSTR-1A, which allows taxpayers to amend or add supply records for the current tax period after filing GSTR-1 but before filing GSTR-3B. This was introduced to provide immediate flexibility for correcting errors before the tax liability is finalized for the month/quarter.

Summary

• Registration Amendments: Available since July 2017.

• Standard GSTR-1 Amendments: Available since the inception of GST filing.

• GSTR-1A: This specific, newer amendment functionality was introduced to allow for real-time corrections between GSTR-1 and GSTR-3B filing.

If you are looking for a specific Government Notification, the amendment procedures are governed by the CGST Rules, 2017 (specifically Rule 19 for registration and various circulars for return filing).

Summary: Amendment options for GST registration and standard GSTR-1 filings have been available since the portal launched in July 2017. The newer GSTR-1A feature, which allows for immediate corrections after filing GSTR-1 but before GSTR-3B, is a more recent addition to streamline the reconciliation process.
