Short answer: both structures give the landowner a share of the same project, and they are taxed differently. Area sharing delivers units — with the capital gains deferral, a prescribed GST valuation, and a funding problem at completion. Revenue sharing delivers cash — which solves the funding problem, may forfeit the deferral, and runs into a valuation rule that was never written.
This page is about the choice between the two, while the terms are still open. For how a JDA is taxed once the structure is settled — both parties, both taxes, scenario by scenario — see how income tax and GST apply to a JDA.
Units or cash: what each structure delivers
Area sharing. The landowner receives a defined share of the constructed project — so many units, or a percentage of built-up area. The developer constructs and hands over. The landowner ends up holding property.
Revenue sharing. The landowner receives a defined share of the proceeds of sale. The developer sells the whole project; receipts are split. The landowner ends up holding cash.
Commercially they can be calibrated to the same value. For tax they are not the same transaction.
Income tax: which structure keeps the deferral
The deferral is written around area sharing
The capital gains deferral for an individual or HUF landowner is written for a specified agreement — one in which the landowner allows development in consideration of a share, being land or building or both, in such project.
That description fits area sharing exactly. The landowner's consideration is a share of the project.
Revenue sharing is the harder case. Where the landowner receives only a share of receipts and no share of the project itself, the arrangement may not answer that description — and if it does not, the deferral does not apply. The gain then falls in the year the development rights are transferred, which is usually the year of signature.
This turns on the drafting, not on the label. Agreements described as revenue sharing sometimes give the landowner an entitlement to units that are then sold on their behalf; agreements described as area sharing sometimes settle in cash. What the document actually confers is what matters, and it is a reason to have the draft read before execution rather than the executed copy read afterwards.
The funding problem, and which structure creates it
Area sharing produces the classic squeeze. At the completion certificate the landowner faces a capital gains charge measured on the stamp duty value of their share — a tax bill on property, with no cash from the transaction to pay it. The units may be sellable, but selling them promptly triggers a short-term gain, because the holding period restarts at the certificate.
Revenue sharing largely dissolves that problem: the landowner receives cash, and the cash is available when the tax falls due. The trade is that the charge may arrive earlier — at signature rather than at completion.
That is the real decision. Deferral with a funding problem, or an earlier charge with the cash to meet it.
