The short version
A joint development (JD) is a transfer of your land, paid for in built units instead of cash. Income tax treats it as a sale, and the gain is a capital gain. The question is when it is taxed and on what value.
The Income-tax Act 1961 has a special rule for this, in section 45(5A), added from the 2017 Finance Act. The Income-tax Act 2025, in force from 1 April 2026, carries the same rule into its capital gains provisions with new section numbers. Commentators describe the substance as unchanged. Ask your chartered accountant (CA) to confirm the current section reference for your return.
Tax can fall due before you have sold a single unit. Plan the cash to pay it from the start of the deal.
Who the special rule covers
The rule applies only when all of these are true:
- You are an individual or a Hindu undivided family (HUF). Companies, firms and LLPs that own land fall outside it.
- The land or building is a capital asset for you. If you hold land as stock in trade, the income is business income, not a capital gain.
- You have signed a registered agreement letting the developer build a project on your land, in exchange for a share in that project, with or without some cash.
If any condition fails, the timing follows the general rules. When a transfer happens under those rules has been argued in the courts for years and can turn on when possession was given and whether the agreement was registered. Take advice before you sign, not after.
When the tax falls due
Under the special rule, the capital gain is taxed in the year the certificate of completion is issued by the authority that approves the building plan, for the whole project or for part of it. In Karnataka this is usually the completion or occupancy certificate issued by the planning authority or local body.
If completion is certified in parts, your CA should work out how much of the gain each part certificate brings in. For a plotted layout, confirm with your CA which document the tax department will treat as the certificate of completion, because layouts are released in stages in many areas.
If you sell your share before completion, the special rule stops applying. The gain is taxed in the year of that sale, under the normal rules for working out the sale value.
How the gain is worked out
| Item | Under the special rule |
|---|---|
| Sale value | The stamp duty value of your share on the date the completion certificate is issued, plus any cash or other payment you received |
| Cost | What you paid for the land, or its value on the date the law allows for very old land, plus improvements |
| Holding period | Land held for more than 24 months gives a long-term gain |
| Rate | Set by the law in force for that year; see below |
Stamp duty value means the government's guidance value for your units, the figure on the Kaveri portal, not the price you or the developer expect to get. If guidance values rise during construction, your taxable gain rises with them. If the market price at completion is lower than the guidance value, raise it with your CA early. Our article on guidance value and market price explains the gap.
Since July 2024, long-term gains on land and buildings are taxed at 12.5 per cent without indexation. A resident individual or HUF who bought the land before 23 July 2024 can instead compute the tax at 20 per cent with indexation and pay the lower of the two. Ask your CA to run both for your land.
Selling your units later
When you later sell the flats or plots you received, that is a second sale. The cost of those units, for working out the second gain, is the value that was taxed under the special rule at completion. So the gain is not taxed twice, but the second sale has its own tax, holding period and rate.
Exemptions
The law allows a capital gain on land to be reduced or exempted if the money, or the gain, is invested in a residential house or in certain notified bonds within set time limits. Whether and how these apply to a JD, where you receive units instead of cash, depends on the facts and has been disputed. Discuss it with your CA before you sign the JDA, because the choices you make then can decide what you can claim later.
TDS on cash you receive
If the developer pays you any money under the JDA, such as a non-refundable deposit or a cash part of the price, it must deduct tax at source (TDS) at 10 per cent, with no minimum amount. A higher rate applies if you do not give the developer your PAN. The rule continues under the Income-tax Act 2025.
A refundable deposit that the developer gets back when your share is handed over is treated differently from a non-refundable one. The JDA should say clearly which kind it is.
GST on a joint development
For residential projects since 1 April 2019, the GST on the development rights you give and on the construction of your units is in most cases the developer's liability, not yours. The details turn on how much of the project is residential, how many units are sold before completion, and the value of similar units sold to buyers.
Two points matter to you:
- If you sell your own units before completion, you may owe GST on those sales yourself, with credit for the GST the developer charged on building them. Selling after the completion certificate is generally outside GST.
- Commercial space in the project is taxed differently from residential.
Ask the developer, in writing, what GST it will charge you and why. Have a CA check it.
What to settle in the JDA
- That the agreement will be registered, and who pays stamp duty and registration.
- Whether any money paid to you is a refundable or a non-refundable deposit.
- The date by which the completion certificate must be applied for, since it fixes your tax year.
- Who bears GST on your units.
- That you get copies of the completion certificate and each part certificate as soon as they are issued.
The tax department matches registered JDAs with landowners' returns. In September 2025 it issued internal instructions for officers to trace JDAs from RERA records and check that the gains were reported. Report the gain in the right year.
You can read the department's own guidance on the Income Tax Department website. For the rest of the deal, start with our landowner's guide to joint development, and see JDA, GPA and the sale deed for the papers and what share a landowner should get for the split.
How we help
We are not your tax adviser, but we build the JD around the tax. We model when tax falls due and what cash you will have then, keep the deposit and completion terms clear in the JDA, and work with your CA so the deal you sign is one you can pay tax on.
