What these bonds do
Capital-gains bonds are a way to make a long-term gain on land or a building tax-free without buying another property. You take the gain and invest it in bonds issued by specified public-sector entities, and to the extent you do so within the rules, that gain is exempt under Section 54EC.
The bonds are plain, low-risk instruments from AAA-rated government-backed issuers. They pay a modest fixed rate of interest. That interest is itself taxable, and return your capital at maturity. The point is not the yield; it is parking the gain to shelter it from a far larger capital-gains tax.
The window, the ceiling and the lock-in
Three rules govern the relief, and all three are firm.
| Rule | What it means |
|---|---|
| Six-month window | Invest the gain in the bonds within six months of the sale |
| ₹50 lakh cap | At most ₹50 lakh of investment counts per financial year |
| Five-year lock-in | The bonds cannot be sold or pledged for five years |
The ₹50 lakh ceiling is the one that surprises sellers of larger properties: it limits the investment recognised across financial years for a single transfer, so you cannot shelter, say, an eighty-lakh gain entirely through 54EC alone. If you redeem or borrow against the bonds before five years, the exemption you claimed is withdrawn and that gain becomes taxable in the year you broke the lock-in.
Bonds, a new house, or both
Section 54EC is one of two main shelters for a property gain; the other is buying a new residential house under Section 54. They are not mutually exclusive. A seller with a large gain often uses both, bonds for up to ₹50 lakh and a new house for the rest, because each has its own separate limit.
Which mix is right depends on whether you actually want another property, how much the gain is, and how soon you need the money back. Bonds tie up capital for five years at a low return but ask nothing of you beyond the investment; a house is a bigger commitment with its own two- and three-year deadlines. The choice is a planning decision made against your specific numbers, not a default.
A worked example: Meera's plot in Jaipur
Meera, an NRI in London, sells an inherited plot in Jaipur in 2026 and makes a long-term gain of seventy lakh. She has no wish to buy another property in India.
Within six months of the sale she invests fifty lakh. The most Section 54EC allows, in REC capital-gains bonds. That fifty lakh of gain is exempt. The remaining twenty lakh has no bond shelter left, so it is taxed as a long-term gain at the flat 12.5% NRI rate, roughly two and a half lakh before surcharge and cess.
If she had wanted to shelter the whole seventy lakh, she could have paired the fifty-lakh bond investment with a Section 54 house purchase for the balance. The bonds then sit locked for five years and return her capital in 2031; the interest they pay along the way is taxable in her hands each year.
