Section 12(3): Immovable Property and the Proportionate Rule

Section 12 explained: this guide covers what it means, who it applies to, the step-by-step process, documents required, fees, due dates and penalties in India — so you can stay compliant with confidence and avoid costly mistakes.

The largest of the specific rules, covering everything from an architect's fee to a hotel room — and containing the Act's first apportionment mechanism.

Section 12(3): the place of supply of services (a) directly in relation to an immovable property, including services by architects, interior decorators, surveyors, engineers and other related experts or estate agents, any service by way of grant of rights to use immovable property or for carrying out or co-ordination of construction work; (b) by way of lodging accommodation by a hotel, inn, guest house, home stay, club or campsite, including a house boat or any other vessel; (c) by way of accommodation in any immovable property for organising any marriage or reception, or official, social, cultural, religious or business function, including services provided in relation to such function at such property; and (d) any services ancillary to (a), (b) and (c) — shall be the location at which the immovable property or boat or vessel is located or intended to be located. The proviso: if it is located or intended to be located outside India, the place of supply is the location of the recipient. The Explanation: where it is located in more than one State or Union territory, the supply is treated as made in each, in proportion to the value collected or determined under the contract, or on such other basis as may be prescribed.

The four categories

(a) Directly in relation to an immovable property. The named professionals — architects, interior decorators, surveyors, engineers, other related experts, estate agents — plus grant of rights to use immovable property, and carrying out or co-ordination of construction work.

"Directly in relation to" is the qualifier. A service that merely concerns a business which happens to own property is not within it; the service must relate directly to the property.

(b) Lodging accommodation. By a hotel, inn, guest house, home stay, club or campsite, by whatever name called — and expressly including a house boat or any other vessel.

(c) Accommodation for functions. Accommodation in any immovable property for organising a marriage or reception, or an official, social, cultural, religious or business function — including services provided in relation to such function at such property. So the catering, decoration and other services provided at the venue in relation to the function fall here, not under s.12(4).

(d) Ancillary services to any of the above.

"Located or intended to be located"

The phrase covers property that does not yet exist.

So a service supplied before construction — architectural design, feasibility, site survey, project co-ordination for a building not yet built — has its place of supply where the property is intended to be located.

That is important for pre-construction professional services, because the default rule in s.12(2) would put the place of supply at the recipient's location, and s.12(3) displaces it to the site.

The practical consequence for the professional: an architect in Maharashtra designing a building in Gujarat makes an inter-State supply, with the place of supply in Gujarat — even where the client is registered in Maharashtra. And the client's credit accrues against Gujarat, which it can use only if it is registered there.

Which is why place of supply drives registration decisions for professionals and their clients on project work. When a second State registration becomes mandatory →

The proviso: property outside India

"Provided that if the location of the immovable property or boat or vessel is located or intended to be located outside India, the place of supply shall be the location of the recipient."

So s.12(3) does not export the place of supply. Where both supplier and recipient are in India — as s.12(1) requires for the section to apply at all — and the property is abroad, the place of supply reverts to the recipient's location, keeping the supply within India.

Contrast s.13(4), which applies where the supplier or recipient is outside India: there the place of supply is where the immovable property is located or intended to be located, without a proviso bringing it back. Section 13(4) →

The Explanation: apportionment across States

"Where the immovable property or boat or vessel is located in more than one State or Union territory, the supply of services shall be treated as made in each of the respective States or Union territories, in proportion to the value for services separately collected or determined in terms of the contract or agreement entered into in this regard or, in the absence of such contract or agreement, on such other basis as may be prescribed."

This is the Act's apportionment mechanism, and it recurs in s.12(7) for events, s.12(11) for leased circuits, s.12(14) for government advertisements and s.13(7) for cross-border services in more than one State.

The hierarchy it establishes:

1. Value separately collected under the contract — where the contract prices the work State by State;
2. Value determined in terms of the contract or agreement — where the contract provides a basis for apportionment even if not separately priced;
3. Such other basis as may be prescribed — the rules step in only where the contract is silent.

So the contract controls the apportionment, and drafting it is the cheapest way to fix the outcome.

Where it applies: a pipeline, a transmission line, a highway, a fibre route, a chain of warehouses, or a leased circuit spanning States. In each case the supply is treated as made in each State, with the value split.

The practical drafting point: a contract for multi-State work should state the value attributable to each State, or at least the basis on which it is to be determined. Without it, the apportionment falls to whatever is prescribed, and both parties lose control of where the credit lands.

Where section 12(3) is often got wrong

Renting of immovable property. Squarely within clause (a) as a grant of rights to use immovable property — the place of supply is the property's location, not the landlord's or the tenant's. So a landlord in one State letting property in another makes an inter-State supply.

Hotel accommodation for a corporate customer. Clause (b) puts the place of supply at the hotel's location, whatever the customer's registration. So a Delhi-registered company booking a Bengaluru hotel receives a supply with its place of supply in Karnataka, and the CGST and SGST charged are not creditable to the Delhi registration.

Event venues. Where the service is accommodation in immovable property for a function, clause (c) applies and the place of supply is the venue. Where it is organisation of an event, s.12(7) applies with a different test. The distinction matters. Section 12(6) and 12(7) →

Works contract services. A works contract is a service in relation to immovable property, determined under s.12(3) — not under the goods rules in s.10, even though goods are used. Works contract classification →

Key takeaways

• Section 12(3) covers four categories, all determined by the property's location.
• "Located or intended to be located" reaches services supplied before construction.
• The proviso returns the place of supply to the recipient where the property is outside India.
• The Explanation apportions across States in proportion to the contract value — so the contract controls.
• Renting and hotel accommodation are within it, so credit accrues at the property's location.
• Distinguish accommodation for a function (12(3)(c)) from event organisation (12(7)).
