GST Name Change & Mobile Number Change in GST Registration Online

What is GST Amendment?

GST amendment means making changes or corrections in your existing GST registration details. After your registration is done, if any information changes — like business address, business type, contact details, authorized signatory, etc. — then you have to update those changes on the GST Portal using amendment application.

Types of GST Amendments:

• Core Field Amendment: Like legal name of business, principal place of business, addition/deletion of partners/directors, etc.
• Non-Core Field Amendment: Contact details, bank account info, etc.
• Amendment in Business Details due to Errors: If wrong information is filled by mistake then correction is required.

Important: Some fields require approval of tax officer (core fields), and some get auto-approved instantly (non-core).

Why is GST Amendment Important

Imagine your business shifted from Mumbai to Delhi, and you did not change the address in your GST profile. What will happen when the department inspects? Or when your invoice is made, it will be made at the old address – which is non-compliance.

GST amendment is necessary:

• For legal compliance
• For proper invoicing
• To avoid problems in departmental verification
• To avoid refund claim rejection
• For business credibility

Another example – if your bank account details are wrong on GST, then the refund can go to the wrong account. So keeping every detail updated ensures smooth operation of the business.
