Across R A Puram, Mylapore, Adyar, Gopalapuram and Alwarpet, many families who own an old bungalow on a ground or two of land choose to redevelop rather than sell outright. The usual structure is a joint development agreement (JDA): the family gives the land to a builder, the builder constructs an apartment block, and the family receives a share of the flats, sometimes with a cash payment. The tax consequences span income tax, GST, TDS and stamp duty, and the family usually has several co-owners, some of whom may live abroad. This guide sets out how the landowner side is taxed.
When does a Chennai landowner pay capital gains tax under a JDA?
Direct answer: For an individual or HUF who signs a registered JDA, capital gains are taxed in the tax year the completion certificate is issued for the project (or part of it), not the year of signing. The sale value is the stamp duty value of the owner's share on that date plus any cash received. Transferring your share before completion loses this deferral.
This rule was introduced as section 45(5A) of the Income-tax Act, 1961 for agreements from tax year 2017-18 onwards, and is explained on the Income Tax Department's page on joint development agreements. It continues under the Income-tax Act, 2025, whose TDS provisions refer to the same specified agreement. Before 2017, the tax department often argued the gain arose when possession was handed to the builder, and older Chennai cases turn on that question; if your agreement predates April 2017, the analysis is different.
The holding period runs from when you acquired the land up to the day before the completion certificate. For land held for decades, the gain is almost always long-term. A resident individual or HUF whose land was acquired before 23 July 2024 can compare 12.5% without indexation with 20% on an indexed gain and pay the lower amount, exactly as for an outright sale (see our guide to capital gains on selling Chennai property). For inherited property, the previous owner's cost and holding period carry over.
How is the landowner taxed at each stage of redevelopment?
| Stage | Income tax | TDS and GST |
|---|---|---|
| JDA and power of attorney signed and registered | No gain yet for individuals and HUFs with a registered JDA | Stamp duty and registration on the JDA under Tamil Nadu stamp law |
| Cash or non-refundable deposit received from the developer | Forms part of the consideration, taxed in the completion year | Developer deducts 10% TDS on monetary consideration |
| Construction period | No tax event; do not sell or transfer your share | Developer manages GST on the project |
| Completion certificate issued (whole or part) | Capital gain taxed: stamp duty value of your share plus cash, less cost | Developer pays GST on the flats built for you; TDS credit claimed in this year |
| You sell a flat received | Fresh gain: sale price less the value taxed for that flat | Buyer deducts 1% TDS if the price is ₹50 lakh or more; no GST on sales after completion |
How does the stamp duty value work in Tamil Nadu?
Stamp duty value means the value adopted or assessable by a government authority for stamp duty. In Tamil Nadu, that follows the guideline value for the land and the value adopted for the building when a flat is registered. For a JDA, the question is what your share of the developed project would be valued at for registration on the date the completion certificate is issued. Guideline values change, so the figure cannot be known when you sign; it is worth checking the current values for your survey number on the Tamil Nadu Registration Department portal (tnreginet.gov.in) at signing and again close to completion. Stamp duty on the JDA itself and on any sale of undivided share to the builder's buyers depends on how the documents are structured, and should be confirmed with your documentation lawyer.
What GST applies to development rights and the landowner's flats?
Under the residential real estate scheme in force since 1 April 2019, the GST Council's FAQs on the real estate sector describe three pieces:
- Development rights: supply of development rights for residential apartments is exempt to the extent the flats are booked before the completion certificate. For flats still unbooked at completion, the developer pays tax under reverse charge, capped at 1% of value for affordable housing and 5% for others.
- Construction of the landowner's flats: the developer supplies construction service to the landowner and pays GST on it, valued with reference to similar flats sold to independent buyers. The liability arises at completion or first occupation, whichever is earlier.
- Landowner selling flats: if you sell your flats before the completion certificate, that sale is taxable and you can take credit for the GST the developer charged you. Sales after completion are outside GST.
Whether development rights are taxable at all has been litigated before High Courts, and the treatment of commercial projects differs. Check the current position for your project type before signing, and make sure the JDA states clearly who bears GST.
What does a worked example look like?
A resident individual bought a house on a ground of land in 2005-06 for ₹50 lakh. In 2024 she registers a JDA giving her four flats plus a non-refundable ₹30 lakh, from which the developer deducts ₹3 lakh TDS. The completion certificate is issued in September 2026, when the stamp duty value of her four flats is ₹6.00 crore. Figures in ₹ lakh, before surcharge and cess.
| Step | 12.5% without indexation | 20% with indexation |
|---|---|---|
| Stamp duty value of share plus cash | 630.00 | 630.00 |
| Cost (indexed at CII 384 ÷ 117) | 50.00 | 164.10 |
| Long-term capital gain (tax year 2026-27) | 580.00 | 465.90 |
| Tax | 72.50 | 93.18 |
| Payable (lower), less TDS credit of 3.00 | 69.50 | Not chosen |
If she sells one flat in 2027-28 for ₹1.70 crore, her cost is ₹1.50 crore (one quarter of the stamp duty value already taxed), giving a ₹20 lakh gain. Because she has held that flat for less than 24 months, it is short-term and taxed at slab rates. Note that the tax on the main gain falls due in the completion year even though she received flats rather than cash, so advance tax planning matters; a family may sell one flat early in the following year to fund it, or plan an exemption.
What should families check before signing a JDA?
- Register the JDA; the completion-year rule depends on a registered agreement.
- Record each co-owner's share and each one's PAN; NRI co-owners face different TDS and repatriation rules (see NRI property sale TDS).
- Collect cost evidence: original purchase deed, or the previous owner's deed for inherited property, and improvement bills.
- Agree in writing who pays GST and when the developer will hand over the completion certificate.
- Plan the reinvestment exemption and its timelines before completion, not after.
- Avoid transferring your entitlement before completion unless the tax cost of doing so has been worked out.
