GST on Joint Ventures, Consortiums & AOPs

1. Quick summary: how GST applies to JVs, consortiums and AOPs

A joint venture (JV), consortium or Association of Persons (AOP) is not automatically outside GST merely because its members share costs or profits. The tax result depends on the legal structure, the contractual obligations, who supplies goods or services, who receives them, whether money is a genuine contribution to a common venture or consideration for an identifiable supply, and how the project is actually operated.

2. Legal framework: the GST provisions to read together

The GST analysis usually starts with the definition of “person”, the scope of “supply”, the Schedule I rules for certain supplies without consideration, and the valuation, invoicing and input tax credit provisions. The agreement alone is important, but it must be read alongside actual conduct and statutory requirements.

3. Identify the structure before deciding GST

3.1 Incorporated special-purpose vehicle (SPV)

Where the parties form a company or LLP to execute the project, the SPV ordinarily contracts in its own name and maintains its own books and GST registrations where required. Transactions between the SPV and shareholders/partners must still be examined separately: equity subscription is not the same as a service invoice, while management, leasing, secondment, guarantee, equipment or construction services may raise distinct GST questions.

3.2 Unincorporated JV or AOP

An unincorporated arrangement can be treated as a person for GST purposes. Its constitution, common pool, decision-making, sharing of risks and rewards, rights in project assets, obligations to the customer and ability to make supplies should be reviewed. The label “JV” does not itself settle whether a member is supplying services to the JV.

3.3 Consortium where members have separate scopes

Infrastructure tenders often use a lead member and one or more consortium members. Some agreements assign distinct scopes and prices to each member; others make a consortium the single contracting party and provide for joint and several performance. The GST position must follow the actual contract and supply chain—not only the fact that the customer pays the lead member.

3.4 Practical structure matrix

4. Cash calls and member contributions: the critical distinction

CBIC Circular No. 35/9/2018-GST explains that cash-call taxability depends on the facts and the JV agreement. It reproduces two contrasting situations: pooled contributions used to buy machinery for the JV are treated as capital contribution/transaction in money; where the operating member uses its own machinery and performs exploration or production activities for the venture, the activity may constitute a service.

4.1 Example A — genuine contribution used to purchase a project asset

Four members have equal participating interests. Each contributes ₹25 lakh under the approved work programme. The operating member collects ₹1 crore and purchases machinery in the JV's name for use in the common project. The asset is recorded in the JV's asset register and the money is used to meet the JV's own capital requirement.

4.2 Example B — member uses its own machinery and charges the common pool

The operating member owns a crane and deploys it on the project. It charges the JV ₹12 lakh for use of the crane and operating support, and the JV allocates that cost among members based on their participating interests.

4.3 Example C — operating member pays third-party invoices

The operator pays ₹18 lakh to an independent laboratory for project testing and recovers the same amount from members through cash calls. If the JV is the actual recipient and the operator is merely administering payment under the approved budget, the documentation should show the agency/settlement arrangement. If the operator procures the service in its own name and supplies a bundled project service to the JV, the result may differ.

4.4 Cash-call decision checklist

• Does the agreement describe the amount as a contribution to capital/working funds, or as payment for a defined activity?
• Is there a specific service, equipment use, staff deployment, deliverable or asset transfer from one member to another?
• Who contracts with the third-party vendor and who is named as recipient on the invoice?
• Who owns the asset after purchase, and who bears loss, obsolescence and operating risk?
• Is the amount credited to capital/current account or recognised as service revenue and expense?
• Does the approved work programme and budget support the use of funds?
• Are member invoices issued only where a taxable supply actually exists?

5. Transactions between the JV and its members

Member-to-JV, JV-to-member and member-to-member transactions should be assessed individually. The relevant question is whether there is a supply under the CGST Act and whether any special rule—such as Schedule I, related/distinct-person valuation or a specific exemption—applies.

5.1 Cost sharing is not a universal exemption

Shared rent, payroll, insurance, IT systems, consultants and head-office costs are common in project structures. A cost allocation may represent a supply if one entity procures or performs something for another. Conversely, a true joint expenditure paid as agent for the actual recipient may be treated differently if the legal and factual conditions are satisfied.

5.2 Pure agent: apply the conditions, not just the wording

Rule 33 of the CGST Rules excludes qualifying expenditure incurred as a pure agent from the value of a supply only when its conditions are met. These include contractual authorisation, the recipient's liability to the third party, separate indication in the invoice, recovery of only the actual amount, and procurement in addition to the supplier's own service. A “reimbursement” line on an invoice does not independently establish pure-agent status.

6. Consortium and infrastructure project billing

For road, rail, power, water, mining and EPC projects, the agreement must be mapped to the actual supply chain. The customer contract may appoint a lead member, while internal documents allocate separate work packages to members. Neither a lead-member clause nor a profit-sharing ratio alone determines the GST outcome.

6.1 Scenario 1 — separate member scopes and direct customer billing

Member A undertakes civil works worth ₹40 crore and Member B supplies electrical works worth ₹25 crore. The contract/tender and customer approvals permit each member to perform and invoice its own scope directly. In that case, each member's outward supply and tax position should be assessed against its own contractual obligations and invoices.

6.2 Scenario 2 — one consortium contract with a lead member

The employer awards a ₹100 crore contract to the consortium, and the lead member invoices the employer while other members perform defined parts. The analysis must determine whether the consortium/AOP is the supplier to the employer and whether the members are supplying to the consortium, or whether the contractual arrangement supports another supply chain. A tax invoice should not be issued by a member to the employer merely because that member performed physical work if the legal supplier and contractual recipient are different.

6.3 Example — cost allocation is not the same as subcontracting

The figures are illustrative only. They do not establish the GST value or tax rate. The agreement, work orders, invoice chain, ownership of materials, risk allocation and statutory classification must be reviewed before configuring the tax treatment.

6.4 Lead-member checklist

• Identify who is the supplier under the employer's contract and who is the recipient under each member's work order.
• Maintain separate project ledgers for customer revenue, subcontracting, member contributions, common costs and profit allocation.
• Do not issue duplicate invoices for the same underlying work.
• Confirm whether material procurement is made by the lead member as principal or as agent for the JV/member.
• Align GSTIN, place of supply, e-invoice/e-way bill obligations and payment certificates with the actual legal entity.
• Reconcile customer deductions, retention money, advances and milestone certificates to the correct supplier and tax period.

7. GST registration, place of supply and project locations

Registration should be decided for each legal person and State/UT based on the nature and scale of supplies, applicable registration provisions, thresholds and exceptions. A project site in another State does not automatically mean the same legal conclusion for every JV structure. Conversely, a temporary project does not automatically remove registration obligations.

7.1 Questions to resolve before commencement

• Is the JV/AOP itself the supplier under the contract, or are the members contracting directly?
• Does the JV/AOP have a separate PAN and bank account, and how will it apply for registration if required?
• In which State is the supplier located, where is the recipient registered, and what is the place of supply?
• Does the project involve immovable property, construction/works-contract services, goods movement or services connected with a specific site?
• Are multiple GST registrations held by the same legal person, potentially creating distinct-person transactions?
• Who is responsible for returns, tax payment, e-invoicing, e-way bills and notices?

7.2 Registration does not solve supplier identity by itself

A GSTIN is a compliance registration, not a substitute for deciding who actually supplies under the contract. If invoices are issued by one member while the agreement and purchase order identify another supplier, the mismatch may create disputes over tax liability and ITC. Resolve the structure before the first invoice.

8. Input tax credit: who can claim it?

ITC is not automatically available to all members merely because they participate in the project or bear a share of the cost. The claimant must satisfy Section 16 and the applicable rules, including possession of a valid tax invoice/debit note, receipt of goods/services, tax-reporting conditions, filing requirements, payment conditions and restrictions under Section 17.

8.1 Example — invoice issued to the JV, cost allocated to members

A vendor issues an invoice for ₹10 lakh plus GST to the registered JV. The JV records the service and allocates ₹4 lakh to Member A and ₹6 lakh to Member B in management accounts. The members cannot assume they can claim their allocated portion of the vendor's GST simply because the expense is shared. Determine the actual recipient, applicable GST registration and lawful invoice chain. If the JV is the recipient and eligible claimant, the JV's own ITC position must be tested.

8.2 Example — vendor invoice issued directly to a member

A supplier invoices Member A for project materials, but the materials are delivered to the JV site and ultimately used for a contract performed by the JV. The recipient, contractual purchase, delivery, ownership and actual use must be reconciled. A delivery address alone does not automatically make the JV the invoice recipient; equally, an invoice in a member's name should not be claimed without satisfying the statutory conditions.

8.3 ITC controls for JV projects

• Maintain invoice-level matching between purchase register, GSTR-2B, supplier GSTIN and the entity claiming credit.
• Check blocked credits under Section 17(5), including restrictions relevant to motor vehicles, works contract/construction of immovable property, personal consumption, gifts/free samples and lost/destroyed/written-off goods, as applicable.
• Separate taxable project inputs from exempt/non-business use and apply common-credit apportionment where required.
• Do not distribute an input tax credit through a cost-allocation journal entry unless the statutory mechanism permits it.
• Reconcile reversals, reclaim, credit notes, retention and advances to the correct GSTIN and return period.
• Review whether an Input Service Distributor (ISD) mechanism is mandatory/applicable for common input-service credits under the law effective for the relevant period.

9. Accounting entries and GST documentation

Accounting treatment is evidence of the transaction but does not independently decide GST. The books should distinguish member capital/current-account contributions, vendor payments, member-provided services, loans, reimbursements, profit allocation and recoveries.

9.1 Illustrative entry — cash contribution to common pool

This is an illustrative accounting format only. The correct ledger depends on the agreement and applicable accounting framework. The entry should be supported by a cash-call notice, contribution calculation, approval and bank evidence.

9.2 Illustrative entry — taxable service supplied by a member

The 18% rate is only an assumed illustration, not a rate conclusion for any specific service. Confirm classification, rate, place/time of supply, invoice and ITC eligibility before posting.

9.3 Minimum document pack

• Executed JV/consortium agreement and all amendments.
• Customer contract, tender, work orders and scope/value allocation.
• Approved work programme, project budget and cash-call approvals.
• Member contribution notices, bank statements and capital/current-account reconciliation.
• Asset register showing purchaser, owner, custodian, project use and disposal.
• Third-party vendor invoices, goods receipt, service completion and payment evidence.
• Member invoices for actual taxable supplies and the corresponding GSTR-1/3B/GSTR-2B trail.
• Monthly reconciliation between project accounts, GST returns and member ledgers.

10. Returns, invoicing, e-invoicing and project reconciliations

Once the supplier/recipient chain is established, build compliance around that chain. Do not create invoices simply to make the ledger balance, and do not omit a taxable service because it was settled through a cash call or a net-off.

10.1 Suggested monthly reconciliation

Keep separate exception categories: unexplained cash-call balance, missing supplier invoice, duplicate billing, wrong GSTIN, ITC claimed by wrong entity, taxable member service not invoiced, unallocated common expense, mismatch between contract revenue and GSTR-1, and credit notes not reflected in project accounts.

11. Industry-specific examples

11.1 Road / HAM / EPC project

A consortium wins a road project. One member provides equipment, another undertakes civil works, and a lead member handles employer billing. The team must decide whether the equipment and civil work are supplies to the JV/consortium, whether the lead member acts as principal or agent, who owns materials and who is the supplier to the authority. Retention, mobilisation advances, milestone bills and O&M services should be mapped separately.

11.2 Oil, gas and mining JV

Members contribute according to participating interests to fund an approved exploration programme. A cash call used to pay third-party drilling invoices may differ from a member charging for its own rigs, technical personnel or operating services. Keep the approved programme, cash-call workings, ownership of equipment and vendor invoices. Circular 35/9/2018-GST and the relevant facts must be considered; do not treat a result from one production-sharing contract as automatic for every JV.

11.3 Real estate development JV

A landowner and developer collaborate to construct and sell units. The GST analysis must distinguish development rights/land-related arrangements, construction services, consideration in cash or kind, supplies to landowner/allottees, registration structure and time-of-supply rules. This is a separate specialised area; do not rely only on the general cash-call principles in this guide.

11.4 Power, water and industrial utilities

Members pool funds to build a common facility, then the facility supplies electricity, water, steam or maintenance to the members. Contributions for project funding must be separated from recurring utility charges, operation and maintenance fees, equipment rentals and recoveries for actual consumption. Apply the relevant rate/exemption entry and valuation to each outward supply.

11.5 IT, engineering and professional consortium

Two firms jointly bid for an engineering or technology project. One supplies design and the other software implementation. If each has a direct customer contract, the invoice chain may be different from a structure where the AOP is the single supplier and members subcontract to it. Define deliverables, acceptance, IP ownership, support obligations and customer liability in the agreement.

11.6 Manufacturing / procurement consortium

Members bulk-purchase materials to obtain better pricing. Establish whether the lead member buys and resells goods, acts as agent for disclosed principals, or merely coordinates procurement for a jointly owned venture. Ownership, risk, title transfer, vendor invoice recipient, stock records and any onward supply must be consistent.

12. Case law and official clarification: what they actually establish

JV disputes are highly fact-sensitive. The following decisions are useful for framing arguments, but they should not be presented as a blanket exemption for all member-to-JV transactions. Several decisions arose under the former service-tax regime, and their application to GST must be considered alongside the CGST Act and Circular No. 35/9/2018-GST.

13. GST departmental audit: common JV red flags

13.1 Audit-ready reconciliation pack

1. JV/consortium agreement and all supplementary agreements.
2. Customer contract and a map of each member's scope and billing rights.
3. Cash-call register tied to approved budgets and bank receipts.
4. Member-wise service invoices and reconciliation to GSTR-1/3B.
5. Purchase register-to-GSTR-2B reconciliation by actual recipient GSTIN.
6. Asset register and evidence for equipment/vehicles deployed across members.
7. Common-cost allocation methodology and pure-agent support, if applicable.
8. ITC eligibility note, reversal/reclaim history and reviewer sign-off.
9. Written explanation of material differences between books, returns and project certificates.

14. Common mistakes to avoid

• Assuming “JV”, “consortium”, “AOP” or “cash call” is a tax exemption category.
• Assuming every payment between members is taxable—or assuming none is taxable because the parties share profits.
• Issuing invoices that do not match the contracting supplier and actual recipient.
• Claiming ITC based only on internal cost allocation when the invoice is addressed to another entity.
• Calling every recharge a pure-agent disbursement without satisfying Rule 33.
• Using a member's equipment, staff or technical resources without evaluating a possible service supply.
• Failing to distinguish capital contribution, loan, interest, profit share, management fee, rental and subcontracting revenue.
• Applying a tribunal ruling under service tax as if it automatically overrides the GST Act or the specific terms of another JV.
• Changing GST treatment based only on accounting nomenclature or an ERP ledger description.
• Ignoring e-invoice, e-way bill, RCM, GST TDS or return obligations that apply to the relevant entity and transaction.

15. Implementation checklist for finance and tax teams

Suggested internal approval note

“The proposed JV/consortium transactions have been mapped to the underlying agreement, supplier-recipient relationship and actual flow of goods/services. Cash calls, capital contributions, member-provided services, common-cost allocations, ITC and invoicing have been reviewed separately. The finance team will not treat a payment as exempt or non-taxable solely on the basis of its ledger description; material treatments will be supported by a written GST analysis and approved documentation.”
