To buy capital gain bonds online, choose one of the four authorized government-backed issuers, open the application on their registrar’s portal, fill in your PAN, bank, and property sale details, and pay through net banking or NEFT/RTGS. Active work takes around 30 minutes. Allotment usually follows 7 to 15 business days after the payment clears. The part that matters more than the clicks is the deadline behind them: your money has to reach the issuer within six months of the date you transferred the property, or the exemption under Section 54EC is gone.
Start With the Six-Month Clock
Section 54EC of the Income Tax Act, 1961 lets you avoid long-term capital gains tax on the sale of land or a building by reinvesting the gain into these bonds. The exemption is proportional. Invest the full gain, up to ₹50 lakh in a financial year, and that portion is fully exempt. Invest less, and only the invested amount is exempt.
The date the clock starts is the date of transfer, which is generally the date on the registered sale deed, not the date the buyer’s money reached you. If the sale proceeds are stuck in escrow or the buyer is slow to pay, the six months keep running anyway. Work backwards from the deadline and give yourself a buffer for allotment, which can take up to 15 business days after payment.
Some quick numbers to keep in mind while you plan the purchase:
- Face value ₹10,000 per bond; minimum investment ₹20,000 (two bonds).
- Maximum ₹50 lakh per financial year across all 54EC bonds combined.
- Fixed interest of 5.25% per annum, paid annually.
- Five-year lock-in. No transfer, pledge, or loan collateral during that period.
- Only long-term gains from land or buildings held over 24 months qualify. Gains from shares, mutual funds, or gold do not.
Get Your Documents Together First
Have all of this ready before you open the portal. Hunting for a document mid-application is how mistakes get typed into forms that later mismatch your tax return.
- PAN card.
- Bank account number and IFSC code for the account where interest should land.
- A scanned cancelled cheque for that account.
- The exact date of transfer, sale consideration, and computed capital gain amount.
- Names of any co-owners if the property was jointly held.
- Address proof (Aadhaar, utility bill, or other government ID).
- Demat account details, if you want the bonds credited electronically.
Get the capital gain figure right. It must match what you will report in your income tax return. A mismatch between your bond application and your ITR invites questions from the assessing officer, and the exemption is proportional to what you actually invested, so a wrong number can cost you real money.
Pick an Issuer
Four entities currently issue Section 54EC bonds: the Rural Electrification Corporation (REC), Power Finance Corporation (PFC), National Highways Authority of India (NHAI), and Indian Railway Finance Corporation (IRFC). The terms are the same across all four: same 5.25% coupon, same five-year lock-in, same tax treatment. The bonds are functionally identical, so the choice usually comes down to which issuer has an open subscription window when you need to invest.
Each issuer routes applications through a registrar. REC’s applications go through KFintech’s portal. PFC hosts its application on pfcindia.co.in. You can also apply through authorized brokers and distributors listed on the issuers’ own sites if you want someone to walk you through it.
The Online Application, Step by Step
Open the Portal and Fill the Form
On the issuer’s bond portal you will usually see two paths: download a physical form, or submit online with electronic payment. Choose the online option. The form asks for your personal details, PAN, contact information, bank account, the property transfer date, and the capital gain amount you’re investing.
Pick your holding mode. Demat is faster and safer than physical certificates, which can be lost in the mail. REC currently offers a ₹500 incentive per investor per financial year for choosing Demat mode.
Complete e-KYC
Once the form is submitted, the portal runs an electronic KYC check. That usually means an OTP to your registered mobile number, and often a real-time cross-check of your PAN against the income tax database. After verification, a summary screen shows your investment amount, payment method, and bond details. Read it carefully before you move to payment.
Pay and Capture the UTR
The portal accepts net banking, NEFT, or RTGS. Net banking is the most direct: the portal redirects you to your bank’s gateway, you authorize the transfer, and you come back with a confirmation. For NEFT or RTGS, you initiate the transfer from your own bank to the issuer’s designated 54EC collection account using the account details and reference number the portal gives you.
Write down the Unique Transaction Reference number your bank issues after the transfer. You’ll enter it on the portal to link the payment to your application, and it is also your evidence of when you invested, which matters if anyone ever questions whether you met the six-month window.
One thing to check twice before you hit send: once money reaches the 54EC collection account, it cannot be refunded for any reason. Confirm the amount and your eligibility first.
Allotment and What to Keep
After payment clears, the issuer verifies your documents and reconciles the funds. Allotment generally takes 7 to 15 business days. If you chose Demat, the bonds are credited to your depository account within a few days of allotment. If you chose physical, the certificate is sent to your registered address by post.
Save the allotment letter and the payment acknowledgment. These are your proof of investment when you claim the Section 54EC exemption on your income tax return, and you’ll want them on hand at maturity as well.
Mistakes That Void the Exemption
The five-year lock-in is absolute. Transferring, converting, or otherwise disposing of the bonds before maturity claws back the exemption entirely, and the previously exempt gain becomes taxable in the year you broke the lock-in rather than the year of the original sale. Using the bonds as loan collateral counts too.
The other common ways people lose the benefit:
- Missing the six-month window because they measured from the payment date instead of the transfer date.
- Investing more than ₹50 lakh in a single financial year. Anything above the cap earns 5.25% for five years with no tax benefit at all.
- Trying to use 54EC bonds for short-term gains, or for gains from shares, mutual funds, or other assets that don’t qualify.
- Entering a capital gain figure on the application that doesn’t match the return.
Have your tax advisor confirm the gain computation before you fill the form. It’s a cheaper conversation than the one you’ll have with the assessing officer if the numbers don’t line up.
Interest and Maturity in Brief
Interest at 5.25% is credited annually to the bank account you gave on the application. On a ₹50 lakh investment that is ₹2,62,500 a year before tax. The interest is fully taxable at your slab rate. No TDS is deducted for resident investors, so you report and pay the tax yourself. NRI investors do have TDS applied. Form 15G or 15H does not apply to these bonds.
At the end of five years the bonds redeem automatically. You don’t need to file a request or surrender any certificate. The principal is credited back to your registered bank account, and the returned amount is not taxable.
