Overview & Legal Framework
GST is a destination-based, multi-stage tax. Every state and Union Territory is treated as a separate jurisdiction under the CGST Act, 2017. A business operating in more than one state must obtain a separate GSTIN for each state — there is no single "national GSTIN" that covers all states.
One GSTIN per State Sec 25(1)
Every person who is liable to be registered under GST shall apply for registration in every State or Union Territory in which he is so liable. A single PAN entity operating in 10 states must obtain 10 separate GSTINs — one for each state/UT.
Distinct Persons Sec 25(4)/(5)
Where a person has obtained or is required to obtain more than one registration — whether in one state (multiple registrations) or in multiple states — each such registration is treated as a distinct person for GST purposes. All inter-unit transactions are taxable supplies.
No Threshold for Inter-State Supply Sec 24(i)
Any person making inter-state taxable supply must register under GST — regardless of aggregate turnover. Even a business with turnover of ₹1 lakh making inter-state supply is required to register. This is a mandatory registration trigger with no threshold exception.
IGST on Inter-Unit Transfers Sec 7(1)(c) r/w Sch I
Stock transfers, services, and common cost recoveries between establishments of the same entity registered in different states (distinct persons) are treated as taxable supplies under Schedule I, Para 2. IGST is charged on such transactions — even if made without consideration.
ITC Available on Cross-State Transactions
Because inter-unit transactions are taxable, ITC is also available on IGST charged between distinct persons. This preserves the credit chain and avoids cascading. The receiving unit claims ITC; the supplying unit reports output tax liability in its GSTR-1 and GSTR-3B.
Place of Supply Rules Determine IGST vs CGST/SGST
The IGST Act, 2017 (Sections 10–13) determines the place of supply for each transaction. If the place of supply is in a different state from the supplier's state, IGST is charged. If both are in the same state, CGST + SGST apply. Multi-state businesses must evaluate place of supply for every transaction.
When Multi-State GST Registration is Required
Section 24 of the CGST Act lists categories where registration is mandatory irrespective of turnover. Section 22 requires registration when aggregate turnover exceeds the threshold. Both apply across all states independently.
Mandatory Triggers for Each State Sec 24
Inter-State Taxable Supplies — No Threshold
Any person making an inter-state taxable supply of goods or services must register — regardless of aggregate turnover. A manufacturer in Maharashtra selling to a buyer in Karnataka must register in Maharashtra. If the same entity also has a warehouse in Karnataka from which it makes local supplies, it must separately register in Karnataka as well.
Casual Taxable Persons (CTP) — Operating in Multiple States
A Casual Taxable Person — one who occasionally makes supplies in a state where they do not have a fixed place of business (e.g., a Delhi trader supplying at a trade fair in Bengaluru) — must register in that state as a CTP before commencing supplies. CTP registration is state-specific, temporary (valid up to 90 days, extendable once), and requires an advance deposit of estimated tax liability.
Threshold-Based Registration in Each State
Even without inter-state supply, if a business has a branch or office in another state and the aggregate turnover (across all states under the same PAN) exceeds ₹40 lakh (goods) / ₹20 lakh (services) / ₹10 lakh (special states), it must register in every state where it has a business establishment and makes taxable supplies. The threshold is computed on aggregate national turnover, not per-state turnover.
E-Commerce Operators — All States of Operation
Every e-commerce operator must register under GST — without any threshold exemption — in every state from which their platform enables supplies. If an e-commerce operator has sellers in multiple states, the operator must register in all states from which it collects TCS (Tax Collected at Source) under Section 52. This is state-specific registration at the operator's place of business in each state.
Distinct Person Supplies — Factories, Warehouses, Branches
Once a business has separate registrations in two or more states, all supplies between such establishments (stock transfers, manpower, shared services cost recovery, management charges, IT services, marketing support) are taxable supplies — even without consideration (i.e., at cost or below cost). This means every inter-branch invoice must carry IGST, and both units must file returns reflecting these transactions.
Non-Resident Taxable Persons (NRTP)
A Non-Resident Taxable Person — a foreign entity making taxable supplies in India without a fixed establishment — must register in each state where it makes such supplies. Like CTP, NRTP registration is temporary (up to 90 days), requires advance tax deposit, and must be obtained before commencing supply. NRTP registration is state-specific and cannot be used across multiple states under a single registration.
State-wise Registration Obligation Matrix
| Business Scenario | State A | State B | State C | Trigger |
|---|---|---|---|---|
| HO in Maharashtra, branch office in Karnataka making local sales | Required | Required | Not required | Sec 22(1) — taxable supply in each state |
| Delhi manufacturer selling inter-state to 15 states | Required (Delhi) | Not required* | Not required* | Sec 24(i) — register in state of supply origin; buyer's state not required if no establishment |
| IT company with registered office in Chennai, delivery centre in Hyderabad, client billing from both | Required (Tamil Nadu) | Required (Telangana) | Not required | Sec 22(1) + Sec 25(1) — fixed establishment in each state making taxable supply |
| Retailer with stores in 8 states (all same PAN) | Required | Required | Required (all 8 states) | Sec 25(1) — separate registration in each state of business |
| Consultant in Mumbai with no office elsewhere, serves clients across India via email/online | Required (Maharashtra) | Not required | Not required | For services, place of supply is location of recipient — supplier need not register in recipient's state if no fixed establishment there |
| Marketplace e-commerce operator with fulfillment centres in 5 states | Required | Required | Required (all 5 states) | Sec 24(x) — mandatory registration for e-commerce operators; TCS in each state of operation |
| Pharmaceutical company: manufacturing in Gujarat, CFA warehouses in 10 states, sales from warehouses | Required (Gujarat) | Required (all warehouse states) | Required (all warehouse states) | Sec 25(1) — fixed establishment (warehouse = additional place of business) in each state making supply |
Distinct Persons — Section 25(4) & 25(5)
This is the most critical concept for multi-state businesses. Each GSTIN, whether in the same state or different states under the same PAN, is treated as a distinct legal person for GST purposes — even though it is the same legal entity under company law.
Section 25(4) — Multiple Registrations, Same PAN
Where a person who has obtained or is required to obtain more than one registration — in the same or different states — each such registration shall be treated as a distinct person. This applies even to additional places of business within the same state if registered separately under Section 25(2).
Section 25(5) — Establishments in Different States
Where a person has an establishment in India and also an establishment outside India, the establishment in India and the establishment outside India shall be treated as distinct persons. This is relevant for import of services by the Indian entity from its overseas parent/subsidiary under reverse charge.
Practical Impact — Intra-Entity Transactions
A company with offices in Tamil Nadu and Maharashtra must:
• Issue tax invoices for all transfers of goods or services between the two registrations
• Charge IGST on such invoices
• File GSTR-1, GSTR-3B in each state
• Reconcile ITC between the two units
• Maintain separate books / cost centres per registration
Valuation of Distinct Person Supplies Rule 28
When goods or services are supplied between distinct persons, the value for GST shall be: (a) Open Market Value, OR (b) if OMV is not available — 90% of the price charged to an unrelated buyer, OR (c) as per cost + 10% margin. If the recipient is eligible for full ITC, the value declared on the invoice is accepted as the transaction value without any challenge.
Illustration: Same PAN, Three States
Registration 1: Maharashtra (GSTIN: 27AABCA1234A1ZX) — Head Office + Manufacturing
Registration 2: Tamil Nadu (GSTIN: 33AABCA1234A1ZP) — Regional Office + Warehouse
Registration 3: Delhi (GSTIN: 07AABCA1234A1ZK) — Sales Office
All three are "distinct persons". ABC Maharashtra sending finished goods to ABC Tamil Nadu warehouse must raise a tax invoice and charge IGST. ABC Tamil Nadu must claim ITC on that IGST and can then sell to its customers in Tamil Nadu charging CGST + SGST (Tamil Nadu). The Delhi unit similarly must receive supplies from Maharashtra under a tax invoice with IGST.
Distinct Persons vs Related Persons — Key Difference
| Parameter | Distinct Persons (Sec 25(4)/(5)) | Related Persons (Sec 2(84)) |
|---|---|---|
| Who qualifies | Same PAN entity with multiple GST registrations (branches, warehouses, head office) | Entities with common ownership, control, officers, or family relationships — may have different PANs |
| Legal basis | Section 25(4)/(5) + Schedule I Para 2 | Section 2(84) + Schedule I Para 2 |
| Taxability of supply | Taxable even without consideration — Schedule I Para 2 | Taxable even without consideration — Schedule I Para 2 |
| Valuation rule | Rule 28 (OMV / 90% / cost + 10%) | Rule 28 (same as distinct persons) |
| GST registration | Same PAN, each GSTIN is a separate taxpayer | Usually separate PANs, each is a separate taxpayer |
| ITC chain | IGST charged → Recipient claims ITC | IGST charged → Recipient claims ITC |
State-wise GSTIN Structure & State Codes
Each GSTIN is a 15-digit alphanumeric number. The first two digits represent the state code of the state in which the registration is granted. This is how a single entity's multiple state registrations can be identified from the GSTIN itself.
27 AABCA1234A 1 Z 527 = State code (Maharashtra) | AABCA1234A = PAN of entity | 1 = Entity number for same PAN in that state (2nd registration in same state = 2, 3rd = 3, up to 9 then A–Z) | Z = Default alphabet | 5 = Check digit
The same PAN in Karnataka would have GSTIN starting with 29AABCA1234A... and in Delhi with 07AABCA1234A...
GST State Codes — All 36 States & UTs

Documents Required for Each State Registration
While the PAN and entity-level documents remain the same across all state registrations, the proof of business presence (principal/additional place of business) must be separately provided for each state. The authorised signatory for each state may also differ.
| Document | Common to All States | State-Specific | Notes |
|---|---|---|---|
| PAN Card | Same PAN used | — | Same entity PAN; GSTIN prefix changes with state code |
| Aadhaar Authentication | Common for promoters | May differ for state-specific authorised signatory | If adding a new authorised signatory for a specific state, their Aadhaar is required |
| Constitution Proof | Same document | — | COI / Partnership deed — same across all states |
| Principal Place of Business (New State) | — | State-specific required | Electricity bill / property tax receipt / rent agreement for the office/warehouse/factory in the new state. Must be in the applicant's name or with NOC if in owner's name. |
| Rental/Lease Agreement | — | State-specific | If renting premises in the new state — rent agreement + NOC from landlord + landlord's address proof |
| Consent Letter | — | If consent premises | If using another person's premises (e.g., relative's property) — consent letter on ₹100 stamp paper + supporting ownership document |
| Bank Account | — | Can be same account | The same bank account can be used across all state GSTINs. Submit cancelled cheque / passbook first page. Must be submitted within 45 days of GSTIN grant. |
| Authorised Signatory | Can be same person | May appoint a local signatory per state | Board resolution / authorisation letter for signatory of each state registration. For companies: Board resolution on company letterhead. |
| Photograph | Common for directors | State-specific signatory photograph if different | Passport size photographs required for each authorised signatory |
| DSC (Digital Signature Certificate) | Same DSC | — | For companies and LLPs: same Class 2/3 DSC used across all state applications. New DSC not required for each state. |
Registration Process — New State GSTIN
Each new state registration requires a fresh Form GST REG-01 application. The process is identical to the first registration, but since the entity is already known to the system (same PAN), some details auto-populate. Aadhaar authentication and officer verification still apply.

Timeline for New State Registration Rule 9 & 10
Input Service Distributor (ISD) & Cross-Charge
Multi-state businesses incur common expenses (rent for HO, software licences, professional fees, advertising) that benefit multiple state registrations. ISD and cross-charge are two mechanisms to distribute such common ITC and costs across states.
Input Service Distributor (ISD) Sec 2(61) & Sec 20
An ISD is a registered office of a taxpayer that receives invoices for common input services (e.g., software, corporate rent, management consulting, insurance) and distributes the ITC to other registrations (branches/units) in proportion to their turnover. ISD registration is a separate GSTIN — typically for the head office — and requires a separate Form GST REG-01 with "Input Service Distributor" as the registration type.
Cross-Charge Sec 7(1)(c) r/w Sch I
Cross-charge is the mechanism where the head office or one unit "charges" another unit for services rendered to it — e.g., HO providing HR, IT, finance, legal services to branches. Since distinct persons are separate taxpayers, HO raises a tax invoice to the branch for the cost of these services (plus margin if applicable). The branch claims ITC on the IGST charged. Cross-charge and ISD are two different, sometimes overlapping, mechanisms.
ISD vs Cross-Charge — When to Use Which
Use ISD: When the HO receives an invoice for a service that purely benefits branches (no activity performed by HO) — e.g., insurance premium for all branches paid through HO.
Use Cross-Charge: When HO itself performs services for branches and recovers cost — e.g., HO's HR team manages recruitment for all branches; HO IT team provides software support to branches. In such cases, HO must raise a tax invoice for the service.
ISD Distribution Formula Rule 39
ITC to be distributed by ISD is allocated to each recipient unit in the ratio of their turnover in the state during the previous financial year (or, for new units, based on estimated turnover). Separate computation required for IGST and CGST+SGST components. ISD files a special return in Form GSTR-6. Each recipient unit receives ITC in Form GSTR-2B.
ISD vs Cross-Charge — Comparison Table
| Parameter | ISD (Sec 2(61) + Sec 20) | Cross-Charge (Sch I Para 2) |
|---|---|---|
| Nature | Mechanism to distribute ITC of common input services | Mechanism to recover cost of services provided by HO to branches |
| When used | Common vendor invoice received at HO for services benefiting all branches | HO's own employees/resources used to serve branches |
| Document raised | ISD Invoice / ISD Credit Note / ISD Debit Note | Tax Invoice by HO to each branch |
| GSTIN required | Separate ISD registration (in same state as HO or a separate state) | No separate GSTIN needed; uses existing HO GSTIN |
| Return filing | GSTR-6 (monthly) by ISD | GSTR-1 (HO reports as B2B supply to branch's GSTIN) |
| ITC in branch's hands | Reflected in GSTR-2B of branch automatically | Branch must reconcile with HO's GSTR-1 filing |
| GST charged | No tax charged — only ITC distributed | IGST at applicable rate charged on the invoice |
| Valuation | Not applicable — ITC distribution, not supply | Rule 28 — OMV / 90% / cost + 10%. If recipient eligible for full ITC, invoice value accepted. |
| CBIC clarification | Circular 199/2023-GST — ISD mandatory for services where ITC needs distribution | Circular 199/2023-GST — Cross-charge for services performed by HO to branches |
(1) Where a common input service invoice is received by the HO and the service benefits only the branches (not HO itself), ISD is the appropriate mechanism — not cross-charge.
(2) Where the HO itself provides services to branches (using its own employees, infrastructure, resources), cross-charge is the appropriate mechanism.
(3) Both ISD and cross-charge can co-exist for the same entity depending on the nature of each expense. Businesses must review their expense categories and route them correctly.
ISD Registration — Additional Requirements
Separate GSTIN for ISD Function
An ISD is registered separately under GST — even if the HO already has a regular GSTIN for the same address. The ISD GSTIN is used exclusively for receiving vendor invoices for common services and distributing ITC to branches. The ISD GSTIN cannot be used for making any taxable supply or claiming ITC for the HO's own use.
Monthly Return for ISD
ISD files Form GSTR-6 monthly by the 13th of the following month. GSTR-6 shows: (a) details of invoices received, (b) total ITC eligible for distribution, (c) ITC distributed to each recipient GSTIN, and (d) ISD invoices/credit notes/debit notes issued. The distributed ITC appears in the recipients' GSTR-2B automatically.
Eligible & Ineligible ITC — ISD Must Segregate
The ISD must distribute only eligible ITC (ITC that would be available to the recipient unit for its own business). ITC blocked under Section 17(5) (motor vehicles, food & beverages, club memberships, etc.) cannot be distributed. ITC attributable exclusively to one unit must be distributed only to that unit — not spread across all units. Pro-rata allocation applies only to common ITC.
Stock Transfers & Branch Billing Across States
Moving goods from one state registration to another — whether to a warehouse, factory, or branch — is a taxable supply under Schedule I. Proper documentation and IGST charging are mandatory.
Step-by-Step: Factory to Warehouse Transfer (Maharashtra → Karnataka)
• Supplier GSTIN: 27AABCA1234A1ZX (Maharashtra)
• Recipient GSTIN: 29AABCA1234A1ZP (Karnataka)
• Place of Supply: Karnataka (29)
• Tax type: IGST (inter-state supply)
• Value: Transfer value as per Rule 28
• IGST amount: Value × applicable rate
State-wise Compliance Obligations
Each state GSTIN is an independent taxpayer. All return filing, tax payment, and reconciliation obligations must be met separately for each GSTIN. There is no consolidated national return or payment under the current GST framework.
| Compliance | Frequency | Due Date | Applicable GSTIN | Notes |
|---|---|---|---|---|
| GSTR-1 / IFF | Monthly (or Quarterly under QRMP) | 11th of next month (Monthly) / 13th of month after quarter (QRMP) | Each state GSTIN separately | All outward B2B, B2C, inter-state, and inter-unit (branch transfer) invoices must be reported. The receiving state's GSTIN sees ITC in GSTR-2B. |
| GSTR-3B | Monthly (or Quarterly under QRMP) | 20th of next month (large taxpayers) / 22nd or 24th (others, staggered by state) | Each state GSTIN separately | Separate tax payment for each state. IGST, CGST, SGST ledgers are state-specific. No netting off between states. |
| GSTR-2B Reconciliation | Monthly | Available 14th of next month | Each state GSTIN separately | Each state GSTIN has its own GSTR-2B. ITC from inter-state supplies (including branch transfers from other states) appears here. |
| GSTR-6 (ISD) | Monthly | 13th of next month | ISD GSTIN only | Only if ISD registration obtained. Shows distribution of ITC to recipient branches across states. |
| GSTR-9 / GSTR-9C | Annual | 31st December of next FY | Each state GSTIN separately | Separate annual return and audit certificate for each GSTIN. GSTR-9C (reconciliation statement) required if turnover of a specific GSTIN exceeds ₹5 crore. |
| E-Way Bill | Per transaction (inter-state goods movement) | Before movement of goods | Sending state GSTIN | Mandatory for all inter-state goods movement above ₹50,000 per consignment. Both the supplier's state GSTIN and the recipient's state GSTIN must be reflected in the E-Way Bill. |
| LUT / Bond (Export) | Annual | Before export in each FY | Exporting state GSTIN | If a specific state GSTIN makes exports (zero-rated supply), that state GSTIN must file a separate LUT (Letter of Undertaking) on the GST portal. A single LUT from the HO does not cover exports from other state GSTINs. |
| TDS (Sec 51) / TCS (Sec 52) | Monthly | 10th of next month | State GSTIN where deduction/collection arises | Government entities deducting TDS must register and file separately in each state. E-commerce operators must register and file TCS returns for each state. |
20th of the month: Taxpayers with annual aggregate turnover above ₹5 crore (all states)
22nd of the month: Taxpayers with aggregate turnover up to ₹5 crore — States: Himachal Pradesh, Punjab, Uttarakhand, Haryana, Rajasthan, Uttar Pradesh, Bihar, Sikkim, Arunachal Pradesh, Nagaland, Manipur, Mizoram, Tripura, Meghalaya, Assam, West Bengal, Jharkhand, Odisha, J&K, Ladakh, Chandigarh, Delhi
24th of the month: Taxpayers with aggregate turnover up to ₹5 crore — States: Maharashtra, Karnataka, Goa, Kerala, Tamil Nadu, Telangana, Andhra Pradesh, MP, Chhattisgarh, Gujarat, Dadra & NH, Daman & Diu, Lakshadweep, Puducherry, Andaman & Nicobar
Multi-state businesses with GSTINs in multiple groups must track each state's due date separately.
Special Category States — Different Thresholds & Rules
Eleven states are designated as "Special Category States" under Article 279A(4)(g) of the Constitution. These states have lower GST registration thresholds and may have additional exemptions. A multi-state business must apply the correct threshold for each state.
Amending, Adding, & Surrendering State Registrations
Business expansion and contraction require corresponding updates to multi-state GST registrations. Each state GSTIN can be independently amended or surrendered. Core field amendments require officer approval; non-core amendments are auto-approved.
Adding a New State GSTIN
When expanding to a new state — new warehouse, new branch office, new franchise — file a fresh Form GST REG-01 for the new state. This is a completely new registration, not an amendment of the existing state GSTIN. Register before or within 30 days of commencing taxable supply in the new state. Section 25(1)
Adding More Branches Within the Same State
If a company already registered in Karnataka opens a second warehouse in Karnataka, it does NOT need a second GSTIN for Karnataka. Instead, amend the existing Karnataka GSTIN using Form GST REG-14 to add the new warehouse as an "additional place of business". A single state can have multiple places of business under one GSTIN. Rule 19
Surrendering / Cancelling a State GSTIN
If a business closes operations in a state — warehouse closed, branch shut — apply for voluntary cancellation of that state's GSTIN in Form GST REG-16. All pending returns up to the cancellation date must be filed, all dues paid. A final return in Form GSTR-10 must be filed within 3 months of cancellation. Reverse ITC on closing stock. Section 29(1)
Change of State (Business Relocation)
If a business relocates from one state to another (e.g., shifting registered office from Mumbai to Bengaluru), the old state GSTIN cannot be transferred. A new GSTIN must be obtained in the new state, and the old state GSTIN must be cancelled. Inter-state transfers of closing stock to the new state GSTIN must be treated as taxable supplies (IGST applicable). The new GSTIN effective date should be coordinated with the cancellation date of the old GSTIN.
Core vs Non-Core Amendments — Multi-State Context Rule 19
Principal Place of Business Address Change in a State
If a company moves its warehouse or branch office to a different address within the same state, this is a core field amendment requiring officer approval within 15 working days. File Form GST REG-14 with the new address proof. The officer in the new state jurisdiction may conduct a physical verification before approving the amendment. Critical: Ensure new address is operational before filing the amendment to pass physical verification if ordered.
Change in State-Level Authorised Signatory
Adding or changing the authorised signatory for a specific state GSTIN involves a core field amendment (addition/deletion of persons) in that state's registration. File REG-14 with the board resolution / authorisation letter for the new signatory and their Aadhaar details. Each state GSTIN can have its own authorised signatory independent of other states.
Bank Account, HSN/SAC Codes, Mobile/Email Updates
Updating bank account details, adding new HSN/SAC codes, changing mobile number or email address of the authorised signatory for a specific state GSTIN are non-core field amendments — auto-approved without officer intervention. File Form GST REG-14; changes effective on submission. These amendments can be made independently for each state GSTIN without affecting other state registrations.
Penalties for Non-Registration & Non-Compliance — Multi-State
Operating without a required state GSTIN — whether through ignorance or deliberate evasion — attracts severe penalties, back-dated tax demands, and even prosecution. Each unregistered state is treated as a separate violation.
Key CBIC Notifications — Multi-State Registration
The following Central Tax notifications directly affect multi-state registration obligations, inter-state supply rules, ISD mechanism, and compliance requirements for businesses operating across states.
Threshold & Exemption Notifications
Enhancement of Goods Threshold to ₹40 Lakh — Most States
Enhanced the registration threshold for goods suppliers from ₹20 lakh to ₹40 lakh in all states that opted for the higher threshold. Directly impacts whether a warehouse-only presence in a general category state crosses the threshold. States that opted to retain ₹20 lakh: Himachal Pradesh, Uttarakhand, J&K, Puducherry, Arunachal Pradesh, Manipur, Meghalaya, Mizoram, Nagaland, Sikkim, Tripura (special category states retain ₹20L for goods).
Date: 07.03.2019 | Effective: 01.04.2019
View Official Notification ↗₹10 Lakh Services Threshold — Special Category States
Notified ₹10 lakh as the registration threshold for service suppliers in 10 special category states. Critical for businesses providing services from branches in NE states — even a small services revenue stream from an office in Manipur or Mizoram above ₹10 lakh requires separate registration in that state. Effective from 01.04.2019.
Date: 07.03.2019 | Effective: 01.04.2019
Exemption from Mandatory Inter-State Registration — Notified Handicraft Goods
Persons making inter-state supplies of notified goods (handloom products, handicrafts, Khadi, coir, zari items, jute items) are exempt from the mandatory registration requirement under Section 24(i) — provided their aggregate turnover is below the applicable threshold. Relevant for artisans and weavers in special category states who sell to buyers in other states. Amended by Notification 03/2018-IT.
Date: 13.10.2017
ISD & Cross-Charge Clarifications
Comprehensive Clarification — ISD vs Cross-Charge for Multi-State Businesses
The most important circular for multi-state businesses. Clarifies: (1) ISD is appropriate where HO receives vendor invoice for services benefiting only branches. (2) Cross-charge is appropriate where HO itself performs services for branches. (3) Both mechanisms can co-exist. (4) If recipient branch is eligible for full ITC, the value of cross-charge is not challengeable. (5) Salaried employees of HO working for branches — cost must be cross-charged; even if free of cost, Schedule I Para 2 treats it as supply. (6) ISD is not mandatory where full ITC is available at recipient.
Date: 17.07.2023
View on CBIC Portal ↗ISD Made Mandatory w.e.f. 01.04.2025 — Finance Act 2024
The Finance Act 2024 amended Section 20 to make ISD registration mandatory for all taxpayers receiving common input service invoices (like rent, insurance, professional services, software licences) that are used by multiple state GSTINs. W.e.f. 01.04.2025, businesses cannot continue routing all common service ITC through cross-charge alone — they must register as ISD and distribute ITC via GSTR-6. Multi-state businesses need to review their current cross-charge structure and set up ISD by April 2025.
Finance Act 2024 | Effective: 01.04.2025
Clarification on Place of Supply for Services Between Distinct Persons
Clarified the place of supply rules for B2B services between distinct persons (different state GSTINs of the same entity). Place of supply is the location of the recipient's GSTIN. This determines whether IGST or CGST+SGST applies on the cross-charge invoice. For example, HO in Maharashtra providing IT support services to Tamil Nadu branch: place of supply is Tamil Nadu — IGST applies on the HO's invoice to the TN branch.
Date: 2024
Process & E-Way Bill Notifications
E-Way Bill Threshold — ₹50,000 for Inter-State Movement
E-Way Bill is mandatory for movement of goods where the consignment value exceeds ₹50,000 for inter-state supplies. Applies to all stock transfers between distinct persons (branch-to-branch, factory-to-warehouse) across states. No exemption for intra-company transfers — E-Way Bill is required even for own stock movement across state borders.

Deemed Registration in 7 Working Days — Aadhaar Authenticated Applications
Amended Rule 9 to provide that if no action is taken by the proper officer within 7 working days on an Aadhaar-authenticated application, registration is deemed granted. This 7-day deemed approval applies to each new state registration as well — beneficial for businesses rapidly expanding to new states and needing quick GSTIN activation to commence operations and billing.

Bank Account Details — 45-Day Rule for Each New State GSTIN
The 45-day bank account submission rule (Rule 10A) applies independently to each state GSTIN at the time of its grant. For multi-state businesses, each new state registration starts its own 45-day clock. Failure to submit bank details for a specific state GSTIN — even if other state GSTINs have bank details — results in a Form GST REG-31 notice for that specific GSTIN and potential suspension of returns filing for that state.

Multi-State GST Compliance Checklist
Use this checklist when expanding to a new state, reviewing existing multi-state compliance, or during annual GST audit. Each point applies per state GSTIN.
- Identify all states where the business has a fixed establishment (office, warehouse, factory, depot, CFA) making taxable supplies — each requires a separate GSTIN.
- Verify that the registration in each state was obtained within 30 days of commencing taxable supply or reaching the threshold in that state — avoid back-dated liability.
- Ensure the principal place of business address document (rent agreement / electricity bill / property tax) for each state is current, in the company's name, and matches the GST registration records.
- Confirm that each state GSTIN has an active authorised signatory with valid Aadhaar — if the DSC of the signatory has expired, renew it to maintain filing capability.
- Verify that bank account details have been submitted for every state GSTIN within 45 days of grant (Rule 10A) — non-submission leads to GST REG-31 notice and suspension.
- Set up GSTR-1 and GSTR-3B filing calendar for every state GSTIN — different due dates apply based on the state and turnover category.
- Ensure all inter-state stock transfers (factory to warehouse, HO to branch) are supported by IGST tax invoices, E-Way Bills, and reflected in GSTR-1 of the sending state and ITC claimed in GSTR-3B of the receiving state.
- Review whether the business needs an ISD registration — especially after the Finance Act 2024 making ISD mandatory w.e.f. 01.04.2025 for common input services distributed across multiple state GSTINs.
- Ensure cross-charge invoices are raised by the head office to each branch for employee costs, management charges, IT support, and other HO services — Schedule I Para 2 requires this even without consideration.
- Validate that the valuation of inter-unit (distinct person) supplies follows Rule 28 — OMV, or 90% of selling price to unrelated buyers, or cost + 10% markup where applicable.
- Reconcile GSTR-2B of each receiving state GSTIN against GSTR-1 of the supplying state GSTIN monthly — any mismatch must be resolved before annual return filing.
- File separate GSTR-9 (and GSTR-9C if applicable) for each state GSTIN by 31st December — GSTR-9C required where the specific state GSTIN's turnover exceeds ₹5 crore.
- If any state has LUT/Bond for exports, ensure it is renewed annually for that state's GSTIN — a single LUT filed at one state GSTIN does not cover exports from other state GSTINs.
- For warehouses in special category states (NE states, Himachal Pradesh, Uttarakhand, J&K), apply the lower threshold (₹20 lakh goods / ₹10 lakh services) — registration obligations arise earlier than in general states.
- If any state GSTIN is no longer active (warehouse closed, branch wound up), file voluntary cancellation in Form GST REG-16, file GSTR-10 (final return) within 3 months, and reverse ITC on closing stock.
- Maintain state-wise profitability statements aligned with GSTIN-wise turnovers — GSTR-9 annual return must match the financial accounts for that state's GSTIN; a consolidated P&L is insufficient.
Frequently Asked Questions
The most common questions from businesses with multi-state operations, answered with legal references.
No. Under Section 25(1) of the CGST Act, every person liable to be registered must apply in every State or Union Territory from which they make taxable supplies. There is no concept of a "national GSTIN". Each state is a separate jurisdiction. A business making supplies from Tamil Nadu and Maharashtra must have separate GSTINs for both states — 33XXXXXX... and 27XXXXXX... respectively. Using only one state's GSTIN for pan-India supplies constitutes non-registration in the other states and attracts penalties.
Yes, almost certainly. If your warehouses receive goods (via inter-state transfers from Delhi) and then dispatch goods to local buyers in each state, those warehouses are making taxable supplies in those states — triggering Section 22(1) registration requirements in each state. Even if the billing happens from Delhi, the actual supply (delivery of goods) happens from the warehouse state. Additionally, the stock transfer from Delhi HQ to each warehouse is itself an inter-state supply (Section 24(i)) requiring Delhi registration — which you already have. Register in all 8 warehouse states before or within 30 days of commencing local deliveries from each warehouse.
Yes. Under Schedule I, Para 2 of the CGST Act, supplies between distinct persons (different state GSTINs of the same entity) in the course of business are taxable supplies — even without consideration (even at zero value or cost price). IGST must be charged at the applicable rate on the value determined under Rule 28. The receiving warehouse claims ITC on the IGST charged. This was a major change from the pre-GST regime where inter-branch stock transfers were often treated as non-taxable. Failing to charge IGST on inter-state stock transfers is a common audit trigger and results in demands plus penalties.
Both mechanisms handle the distribution of costs/ITC from the head office to branches, but they work differently. ISD (Input Service Distributor) is used when the head office receives a vendor invoice for a service that benefits the branches — the HO does not "perform" the service itself. The HO distributes only the ITC (tax credit) to the branches in proportion to their turnover via Form GSTR-6. No GST is charged by HO to branches. Cross-charge is used when the HO itself performs services for branches (using its own employees, infrastructure) and recovers the cost — HO raises a tax invoice to the branch charging IGST. CBIC Circular 199/2023 clarified this distinction comprehensively. From April 2025 (Finance Act 2024), ISD registration is mandatory for eligible entities. Use ISD for external vendor costs; use cross-charge for intra-company service recovery.
If the ₹8 lakh from Meghalaya is for services and the aggregate national turnover is ₹30 lakh, then: Meghalaya is a special category state with a ₹10 lakh threshold for services. The Meghalaya-specific turnover is ₹8 lakh — below the ₹10 lakh special state threshold. However, aggregate national turnover of ₹30 lakh exceeds ₹20 lakh (general services threshold). The question is whether the threshold comparison is done on aggregate national turnover or state-specific turnover. Under Section 22(1), registration is required where aggregate turnover (all-India, all-PAN) exceeds the threshold applicable in the state. Since ₹30 lakh exceeds ₹10 lakh (Meghalaya's threshold), registration in Meghalaya is required. Importantly, if no fixed establishment exists in Meghalaya and you're only receiving orders from there without a local presence, registration in Meghalaya may not be needed. Consult a GST advisor for your specific structure.
Yes. Under Section 25(2) of the CGST Act, a person having multiple business verticals (distinct business lines) in the same state may obtain a separate registration for each business vertical. This is optional — the default is one GSTIN per state. The "separate business vertical" is defined in Section 2(18) as a distinguishable component of an enterprise that is engaged in providing individual goods or services. Examples: A conglomerate having an IT services division and a manufacturing division in Tamil Nadu can have two separate GSTINs for Tamil Nadu (33XXXXX...1... and 33XXXXX...2...). Each vertical then maintains separate compliance, returns, and ITC. However, all these are treated as "distinct persons" under Section 25(4), so transfers between them within the same state are taxable supplies attracting CGST + SGST.
When closing operations in a state, follow these steps: (1) File all pending GST returns (GSTR-1, GSTR-3B) for the GSTIN up to the date of closure. (2) Reverse ITC on unsold closing stock, capital goods, and inputs on hand as on the cancellation date — reverse under Section 18(4) / Rule 44. Pay the reversed ITC or the tax on the goods (at fair market value), whichever is higher. (3) Apply for voluntary cancellation in Form GST REG-16. (4) After cancellation order is issued, file GSTR-10 (Final Return) within 3 months of the cancellation order / date of cancellation. (5) Transfer remaining ITC (if any) to another state GSTIN is not possible — ITC is GSTIN-specific and lapses on cancellation. (6) If physical assets are transferred to another state GSTIN of the same entity, charge IGST on the fair market value at the applicable rate.
Yes. E-Way Bill is mandatory for all inter-state movement of goods where the consignment value exceeds ₹50,000 — regardless of whether it is a sale to an unrelated customer or an internal branch transfer to your own warehouse. Since factory and warehouse in different states are "distinct persons", the movement is an inter-state supply (IGST applies), and E-Way Bill is mandatorily required. The E-Way Bill must be generated on the E-Way Bill portal before the goods commence movement. The vehicle number must be updated. Penalty for movement without E-Way Bill: ₹10,000 or the tax amount, whichever is higher, plus the goods can be seized and detained. There is no exemption for intra-company inter-state transfers.
