How to add Additional Place of Business (APOB) in GST: complete 2026 guide

When a business expands to a new branch, warehouse, showroom, fulfilment centre, or virtual office within a state where it is already GST-registered, it must update its GST registration to include the new address as an Additional Place of Business (APOB). This is not optional. Operating from or storing goods at a location that is not declared on the GST certificate is a compliance violation under the CGST Act, 2017 and can result in penalties, Input Tax Credit (ITC) reversals, and GST audit scrutiny.

The process for adding an APOB is an online core field amendment on the GST portal. It does not require a new GSTIN and there is no government fee. However, because adding an APOB is classified as a core amendment, it requires approval by a GST officer before the change takes effect, and the business must provide address proof documents for the new location. Add Additional Place of Business in GST is a mandatory compliance requirement when a business starts operating from a new branch, warehouse, showroom, or office within the same state. Businesses must update their GST registration through a core amendment to avoid penalties, ITC issues, and audit scrutiny.

In 2026, with the GST portal upgraded and CBIC Instruction No. 03/2025-GST firmly in place, the APOB amendment process has become more structured. Officers are now bound by prescribed document lists and timelines, making approvals faster for well-prepared applications.

What is an Additional Place of Business under GST?

Under Section 2(85) of the CGST Act, 2017, a “place of business” includes any place from which business is ordinarily carried on, including a warehouse, godown, or any other place where goods are stored, supplied, or received. It also includes any place where accounts and records relating to the business are maintained.

An Additional Place of Business is any place of business in the same state as the existing GSTIN, other than the Principal Place of Business (PPOB). The PPOB is the primary address declared at the time of original GST registration. All subsequent locations in the same state are APOBs.

Businesses that commonly need to add APOBs include:

• E-commerce sellers using Amazon, Flipkart, or Meesho whose warehouses or fulfilment centres are in the same state as the registered PPOB.
• Manufacturers with multiple production units, godowns, or storage facilities within the same state.
• Retail and services businesses that open new branches, showrooms, or service centres in the same state.
• Businesses that take on a new virtual office address within the same state to use as a compliance address while the operational PPOB remains unchanged.

APOB vs new GST registration: which applies?

The rule is straightforward: APOB applies only when the new location is in the same state as the existing GSTIN. If the new location is in a different state where the business does not have any existing GSTIN, a fresh GST registration is required in that state, with the new address as the PPOB for that registration.

If the business already has a GSTIN in a state and opens an additional location in the same state, that new location is added as an APOB under the existing GSTIN. The business continues to file returns, issue invoices, and report transactions for the entire state under the single GSTIN, with both the PPOB and APOB addresses reflected in the registration certificate.

Core field vs non-core field amendment

Adding an APOB is classified as a core field amendment under Rule 19 of the CGST Rules, 2017. Core field amendments involve changes to key identity and operational details of the GST registration, as opposed to non-core amendments (such as changing a bank account or email address) which take effect automatically without officer approval.

Core field amendments require: submission of the amendment application on the GST portal; review and approval by the assigned GST officer; and an Application Reference Number (ARN) is generated upon submission. The change becomes effective only after the officer approves it. The officer has 15 working days to approve or reject the amendment from the date of ARN generation. If not acted on within 15 working days, the amendment is deemed approved by operation of law.

Documents required for adding an APOB

The documents required for the new APOB address follow the CBIC Instruction No. 03/2025-GST dated April 17, 2025 and are identical to those required when establishing the PPOB.

For owned premises

Any one of the following: latest property tax receipt, municipal khata copy, or electricity bill in the name of the business or the property owner showing the new address.

For rented or leased premises

A valid rent or lease agreement in the name of the registered business for the new address, along with any one of the following documents of the lessor: property tax receipt, municipal khata copy, or electricity bill. If the rent agreement is unregistered, a copy of the lessor’s identity proof must also be submitted.

For premises used with owner’s consent (including virtual offices)

A consent letter or NOC from the property owner, along with one ownership document of the property owner. For a virtual office, the service agreement from the virtual office provider, a signed NOC from the property owner, and the utility bill for the premises serve as the three required documents.

All documents must be in PDF, JPEG, or PNG format and must not exceed the file size limits prescribed on the GST portal. The address in each document must exactly match the address entered in the APOB amendment form.

Step-by-step process for adding an APOB on the GST portal

Step 1: log in to the GST portal. Go to the GST portal and log in using your GSTIN, username, and password. Complete OTP verification if prompted.

Step 2: navigate to Amendment of Registration Core Fields. On the dashboard, click on Services in the top navigation menu. Select Registration from the dropdown. Select Amendment of Registration Core Fields. The system will display the current registration details in edit mode.

Step 3: open the Additional Place of Business tab. Multiple tabs will be visible. Click on the Additional Places of Business tab. If the business has not previously registered any APOB, the option will show Has Additional Place of Business as No. Change this to Yes.

Step 4: click Add New and enter APOB details. Click the Add New button. Enter: nature of premises (owned, rented or leased, or consent based); full address including building number, floor, building name, street, locality, city, state, and PIN code; nature of business activities conducted at the APOB (manufacturing, wholesale, retail, storage of goods, service provision, or office or support function); and date from which the APOB is being added.

Step 5: upload address proof documents. Upload the required documents for the new APOB address in the prescribed format within the file size limits.

Step 6: enter reason for amendment and date. Select Add Place of Business as the reason for amendment. Enter the date of the amendment.

Step 7: save and submit. Click Save after entering all APOB details. Click Submit. The system generates an ARN confirming successful submission. An acknowledgement SMS and email are sent to the registered mobile number and email address within 15 minutes.

Step 8: sign the application. Companies and LLPs are required to sign using a Digital Signature Certificate (DSC). Individual proprietors and partnership firms may use Electronic Verification Code (EVC), which is an OTP sent to the registered mobile number.

Step 9: track amendment status. Track the status using the ARN on the GST portal under Services, then Track Application Status. Status options include Pending for Clarification, Pending for Processing, Approved, and Rejected.

Approval timeline

GST APOB amendments are typically approved within 7 to 15 working days of ARN generation if documents are complete and accurate. The officer has 15 working days from the ARN date to act on the amendment. If the officer does not act within 15 working days, the amendment is deemed approved by operation of law.

Once approved, the GST Registration Certificate (Form REG-06) is updated to reflect the new APOB address. Verify approval by logging in to the GST portal and checking the registration profile, or by downloading the updated REG-06.

What happens during officer scrutiny

After the core amendment is submitted, the assigned GST officer reviews the documents. The officer may issue a query through Form GST REG-03 if additional clarification is required. The applicant must respond within 7 working days using Form GST REG-04. If the officer is not satisfied with the response, the amendment may be rejected via Form GST REG-05. The most common cause of REG-03 queries during APOB additions is an address mismatch between the uploaded documents and the address entered in the form, or a utility bill that is older than two months.

Consequences of not adding an APOB

Failing to declare an APOB when goods are stored or business is conducted from a non-registered location has multiple consequences:

Under Section 125 of the CGST Act, 2017, the general penalty for non-compliance can extend to Rs. 25,000 each for CGST and SGST, totalling Rs. 50,000. Under Section 122(1), specific offences relating to storage of goods without proper registration can attract a penalty of Rs. 10,000 or the tax involved, whichever is higher.

Input Tax Credit (ITC) may be reversed or denied for purchases made at or goods stored from an unregistered location. An unregistered location creates a direct ITC eligibility risk.

If an officer finds goods stored or business conducted from an address that does not appear on the GST certificate, they may issue a demand notice under Section 73 or Section 74 of the CGST Act. Notices that allege deliberate concealment (Section 74) carry a minimum penalty of the tax evaded plus 100% of the tax as penalty.

E-commerce sellers who store goods in Amazon or Flipkart fulfilment centres without declaring those FCs as APOBs may face suspension of their seller accounts in addition to GST penalties. Both Amazon and Flipkart require sellers to confirm that all warehouse addresses are declared on the GST certificate before listing and shipping from those locations.

Adding a virtual office as an APOB

A virtual office address can be added as an APOB under an existing GSTIN using the same core amendment process. This is the most common scenario for businesses that have a physical operational address as their PPOB but want to add a commercial address in a different part of the city or a different business district as a compliance address.

The documents required are the virtual office service agreement, the NOC from the property owner, and the utility bill for the premises, consistent with the PPOB documentation requirements under CBIC Instruction No. 03/2025-GST. The nature of business activity at the virtual office APOB should be declared as an office or support function. This accurately represents the use of the virtual office address for correspondence and compliance purposes.
