Amendment of registration and the officer's discretion
Core fields need approval. Everything else does not. Knowing which is which saves weeks.
An amendment of registration particulars is applied for in REG-14 within fifteen days of the change. Amendments to core fields — the legal name of the business, the principal or additional place of business, and the addition or deletion of partners, directors or other persons responsible for the day to day affairs — require the officer's approval, granted in REG-15 or refused after a notice in REG-03. Non core fields are amended on the portal without approval.
Core and non core
Core fields requiring approval: legal name where the permanent account number does not change, principal place of business, additional places of business, and the addition or deletion of promoters, partners, directors, karta, trustee or persons responsible for the day to day affairs.
Non core fields amended without approval: bank account details, mobile and email of the authorised signatory subject to authentication, and other particulars the rules permit.
A change in the constitution resulting in a change of permanent account number requires a fresh registration, not an amendment.
The fifteen day period runs from the date of the change, and delay is a common ground for a query even though the amendment is ultimately allowed.
Where amendments are refused or delayed
A change of principal place of business, where the new premises documents do not agree on the address, or where verification is adverse.
Addition of a director connected with another registration under investigation, which triggers scrutiny.
Deletion of a partner or director where the department suspects it is intended to escape liability, which is a legitimate concern the reply should address squarely.
In each case reply to REG-03 within the period, with documents, and ask for the verification report where it is adverse.
Why this matters more than it appears
Service of notices and orders is on the email and mobile on record. An outdated authorised signatory is how taxpayers lose appeal windows.
An undeclared additional place of business creates detention and credit exposure.
A director who has resigned but remains on the registration remains exposed to proceedings naming officers of the company.
An annual review of the registration particulars against the corporate record is a fifteen minute exercise that prevents years of difficulty.
What to do on Monday
Review registration particulars annually against the corporate record and the actual premises.
Update the authorised signatory's email and mobile immediately on any change; service depends on them.
Apply within fifteen days of any core field change, with documents that agree.
Remove resigned directors from the registration promptly.

Write to the GST practiceQuestions we are asked on this
How long do we have to apply for an amendment?
Fifteen days from the date of the change, in REG-14.
Does a change of business constitution need an amendment?
Where the permanent account number changes, a fresh registration is required, not an amendment.
Can bank details be changed without approval?
Yes, bank account details are a non core field.
Why does a resigned director remain a problem?
Because proceedings naming officers of the company will name whoever appears on the registration. Update it promptly.
Can an amendment be backdated?
The rules provide for the effective date of an amendment; state the date of the change and support it with the corporate document.
