Your GST registration is supposed to be a live mirror of where your business operates. Open a warehouse, shut a branch, shift your head office, onboard to a new fulfilment centre — each of these events triggers the same legal obligation: an amendment to your registration, filed within 15 days. Miss it, and you’re carrying an outdated certificate that penalties, e-way bill checks, and physical verification drives are increasingly built to catch.
I’m Keshav Sehgal from ComplyLocal Consultants. This guide explains the additional place of business amendment in GST as a complete lifecycle — what counts as an amendment, why APOB is a “core field,” how adding, changing, and deleting a place each work, the forms you’ll encounter from ARN to REG-06, and what late filing actually costs. If you’re only looking for the first-time filing walkthrough, our step-by-step guide on how to add an additional place of business covers every portal screen; this article covers everything around and after it.
What Counts as an APOB Amendment in GST?
An amendment is any change to the places of business recorded on your registration. For the additional place of business under GST, that means three kinds of events:
Adding a new APOB — a warehouse, branch, shop, godown, or marketplace fulfilment centre you’ve started operating from.
Changing an existing entry — correcting or updating the details of a declared place.
Deleting an APOB — removing a place that has ceased to be used for business, with the reason and date of amendment recorded.
All three run through the same route on the portal: Services → Registration → Amendment of Registration (Core Fields), using the Business Details, Principal Place of Business, and Additional Places of Business tabs depending on what’s changing.
Core vs Non-Core Fields: Why APOB Amendment Needs Officer Approval
The GST portal splits registration fields into two classes, and the class decides how your amendment is processed.
Aspect | Core field amendment | Non-core amendment |
|---|---|---|
What it covers | Principal place of business and Additional Place of Business (other than change in State), among other notified core fields | Other registration details outside the notified core list |
Approval | Requires formal application and tax officer approval | Does not go through the same officer-approval process |
Applies to APOB? | Yes — adding, changing, or deleting an APOB is a core field change | No — filing APOB changes through the non-core route is a documented mistake |
Queue rule | Cannot be filed while an earlier core amendment ARN is pending | — |
Why this matters: a recurring misconception is that APOB addition is non-core and auto-approved. It isn’t. It is a notified core field — an officer reviews it, can query it, and can reject it. Plan your timelines around approval, not submission.
When You Must File an APOB Amendment (The 15-Day Rule)
Per the GST Council/CBIC registration guidance, changes relating to the place of business — including additional places — must be applied for within 15 days of the event. In practice, these are the triggers:
You start operations — storage, dispatch, sales, record-keeping — at a new premises in the same State.
A marketplace onboards you to a new fulfilment centre that must appear on your certificate.
You stop using a declared premises — deletion is an amendment too, with the same window.
Your principal place of business itself changes (covered below — same core-field route).
The Central Warehousing Corporation’s GST circular puts the risk plainly for its own units: file the amendment within 15 days of adding or deleting a place, failing which a general penalty of up to ₹25,000 under the CGST Act may be levied.
The Three Amendment Flows: Add, Delete, and Change
Adding a New APOB
Log in → Services → Registration → Amendment of Registration (Core Fields) → Additional Places of Business tab → enter the number of places → ADD NEW → fill the address, nature of possession, and business activity → upload proof → enter the reason and date of amendment → verify with DSC/E-Sign/EVC. If you currently have no APOB, first set “Have Additional Place of Business” = YES on the PPOB tab to unlock the APOB tab. The field-by-field walkthrough, APOB document requirements and filing tips are in the dedicated guides — here, note simply that this is one application, one ARN, one approval.
Deleting an APOB
When a place ceases to be used for business, remove it through the same core-fields route: open the Additional Places of Business tab, delete the entry, and record the reason for amendment and the date of amendment. On approval, the updated REG-06 no longer shows that address. Two practical points:
The 15-day window applies to deletion just as it does to addition — the CWC circular expressly covers places “added or deleted.”
Keep your e-way bill and dispatch practices aligned: once a premises is off the certificate, goods movement shouldn’t show it as a business address.
Changing Your Principal Place of Business
The principal place of business is a core field too, amended through the same application — you simply work in the Principal Place of Business tab instead of (or alongside) the APOB tab. This is how businesses shifting their head office within the State handle it. Remember the boundary: a change of State cannot be done by amendment at all — operating from another State needs a separate registration under Section 25, not an amended one.
Forms and Orders in the Amendment Lifecycle
From submission to updated certificate, these are the references you’ll see:
Stage | Form / reference | What it means for you |
|---|---|---|
Submission | ARN (Application Reference Number) | Generated on filing with acknowledgment; use it under Track Application Status |
Clarification | REG-03 | Officer seeks more information or better documents |
Your reply | REG-04 | Must be filed within 7 working days of REG-03, or the application can be rejected automatically |
Decision | REG-15 | The approval order, communicated via SMS/email |
Updated certificate | REG-06 | Download the refreshed certificate showing the amended places of business |
Timelines: Filing Window and Approval Duration
Filing: within 15 days of the change in place of business.
Approval: the officer typically acts within internal timelines of around 15 days, though actual duration varies by jurisdiction and whether a REG-03 round is raised.
Clarification: a REG-03 adds the 7-working-day REG-04 reply window plus fresh processing time.
Queue: a new core amendment cannot be filed while an earlier core amendment ARN is pending — batch related changes into one application instead of filing serially.
What Late or Missed Amendment Actually Costs
There is no dedicated “late APOB amendment” penalty section. Enforcement runs through the general and movement provisions — and real-world practice is graduated:
Situation | Documented consequence |
|---|---|
Amendment not filed for a place of business added or deleted | General penalty up to ₹25,000 under Section 125 CGST Act (expressly cited in the CWC circular) |
Recent rental agreement, APOB simply not yet updated (Tamil Nadu guidance) | Minor penalty of ₹5,000 |
No ARN or proof of amendment produced (Tamil Nadu guidance) | Penalty of ₹25,000 |
Repeated offences; goods moving to/from undeclared premises | Maximum penalties under Section 129 (detention on movement) |
Undeclared premises found in verification drives | Clarification notices; in serious cases suspension or cancellation of the GSTIN |
The pattern to notice: an amendment filed late but filed is treated far more leniently than an amendment never filed. If you’ve missed the 15-day window, the right move is still to file now — an ARN in hand is exactly what the graduated Tamil Nadu approach rewards.
Amendment Rules That Trip People Up
The pending-ARN block. One core amendment at a time — a second filing is impossible until the first is decided. Bundle your changes.
The non-core shortcut. APOB changes filed through the non-core route don’t register the change — a documented mistake that leaves your certificate unamended while you believe you’ve complied.
Geocoding expectations. The portal now uses map-based address selection with automated warnings where the locality or PIN doesn’t match, and geocoded addresses may be required for core amendments. Geo-tagging is a one-time activity per address — place the pin correctly the first time.
Operating before approval. Billing or dispatching from a premises that isn’t yet on your certificate can be treated as operating from an undeclared location. The amendment protects you only once REG-06 reflects it.
Trying to amend across States. APOB amendment works only within the State of the GSTIN; another State means a fresh registration, not an amendment.
Expert Tips from ComplyLocal Consultants
Treat every lease signing, branch closure, and FC onboarding email as the start of a 15-day countdown — put the amendment task in the same workflow as the business event.
Batch changes: adding one warehouse and deleting another can travel in a single core-field application, avoiding the pending-ARN trap.
Save every ARN and REG-15/REG-06 in a compliance folder — producing the ARN is precisely what separates a ₹5,000 outcome from a ₹25,000 one in graduated enforcement.
After approval, re-download REG-06 and update marketplaces, transporters, and your e-way bill practices the same day.
If amendments keep slipping through the cracks — common once you’re juggling several FCs — our APOB registration service handles filings, REG-03 replies, and certificate updates end to end.

Conclusion
An APOB amendment isn’t a form — it’s a discipline. Every change on the ground gets mirrored on the certificate within 15 days, through one core-field application at a time, and nothing operates from a new address until REG-06 says so. Adding, changing, and deleting all run the same track: application, ARN, possible REG-03, decision in REG-15, updated certificate.
The businesses that get amendments wrong aren’t usually careless — they’re busy, and the 15-day window closes while the warehouse is being racked. Build the amendment into the expansion checklist itself, and the compliance takes care of itself.
