Capital Gains Account Scheme (CGAS): The Parking Lot That Saves Your Section 54 Exemption
TL;DR
- The Capital Gains Account Scheme, 1988 (CGAS) is a government-backed scheme to park unutilised capital gains pending reinvestment.
- It is mandatory if you claim Section 54, 54B, 54F, or 54D exemption but cannot complete the new asset purchase before the ITR due date.
- CGAS accounts can be opened only at notified public sector banks; private banks are excluded.
- Two account types: Type A (savings, withdrawable on demand) and Type B (term deposit, fixed tenure).
- Funds can stay in CGAS for the same period allowed for reinvestment (2 or 3 years), after which any unused balance becomes taxable.
- Withdrawals are restricted and require Form C and Form D for documentation.
What this means in plain terms
You sold a property, made a Rs. 1 crore gain, and plan to use it to buy another house under Section 54. But the ITR due date is 31 July and you only managed to pay Rs. 30 lakhs to the new builder by then. What about the remaining Rs. 70 lakhs of gain?
If that Rs. 70 lakhs is sitting in your savings account on 31 July, you lose the exemption on that portion. The income tax department wants visible commitment to reinvestment, so the rule is: any unutilised portion of the gain must be parked in a CGAS account at a designated public sector bank before the ITR due date. That deposit then earmarks the money for the new property and preserves your full exemption.
How CGAS actually works
The legal foundation
CGAS was notified by the Central Government in 1988 under Sections 54, 54B, 54D, 54F, and 54G of the Income Tax Act. Subsequent additions include Section 54EC (later removed) and Section 54GA. The scheme is administered by the Central Board of Direct Taxes through notified banks.
Where to open a CGAS account
CGAS accounts can be opened only at branches of public sector banks: State Bank of India, Bank of Baroda, Canara Bank, Punjab National Bank, Indian Bank, Union Bank, Bank of India, IDBI Bank, UCO Bank, and Central Bank. Private banks like HDFC, ICICI, and Axis are not authorised to operate CGAS accounts.
Two account types
Type A is a savings account with full liquidity. You can withdraw on demand subject to documentation. Interest is paid at the prevailing savings rate, currently around 2.5-3%. Type B is a term deposit with fixed maturity. The interest rate is the bank's prevailing term deposit rate (5.5-7%) but withdrawals before maturity attract a penalty.
The deadline pressure
The CGAS deposit must be made on or before the ITR due date, typically 31 July following the financial year of the property sale. If the due date is extended (as has happened recently), the CGAS deadline extends with it. Missing this window costs you the exemption.
Operating a CGAS account
Opening the account
Fill Form A at the public sector bank branch with the sale details, exemption section claimed, and amount to be deposited. Provide your PAN, sale deed copy, and KYC documents. The bank issues a passbook for Type A or a deposit receipt for Type B.
Withdrawing for purchase or construction
Use Form C for the first withdrawal and Form D for subsequent withdrawals, attaching invoices, builder receipts, or registration documents as proof of use. Within 60 days of withdrawal, you must show the bank that the amount was used for the intended purpose; otherwise, redeposit is required.
The 2-year or 3-year timeline
The amount in CGAS must be utilised within the same timeline as the underlying exemption: 2 years for purchase of a new house and 3 years for construction or land for agriculture purposes. The clock starts from the date of original transfer, not the date of CGAS deposit.
Taxability of unutilised balance
If the CGAS balance is not utilised within the prescribed period, the unused amount becomes taxable as LTCG in the previous year in which the period expires. For example, if you sold in May 2025 and the 3-year deadline ends in May 2028, the unused balance is taxed in AY 2029-30.
Common pitfalls and best practices
Wrong section claimed at the time of deposit
When opening the account, you must specify whether the deposit is for Section 54, 54B, 54F, or 54D. Switching later is difficult. If you are unsure, get tax advice before opening so the section ties match the exemption you plan to claim in the ITR.
Mixing personal and CGAS funds
Keep CGAS funds strictly separate. Do not deposit non-capital-gains money into the account. The bank treats every credit as part of the exempted corpus and tracks against the original sale amount.
Withdrawal documentation
Each withdrawal needs supporting purchase or construction evidence. The income tax department can verify CGAS withdrawals during assessment and disallow the exemption if the trail is broken.
Closing the account
To close a CGAS account, you need a No-Objection Certificate from the jurisdictional Assessing Officer. The bank cannot close it on your request alone. This is to ensure that the exemption was actually realised and any taxable residue was reported.
A real example
Karthik, 46, Rs. 28L CTC, Coimbatore, sold his Saibaba Colony apartment in November 2025 for Rs. 1 crore. LTCG worked out to Rs. 65 lakhs. He shortlisted a new flat in Race Course for Rs. 1.1 crores with possession in April 2027.
Step 1: Between November 2025 and June 2026, he paid Rs. 35 lakhs to the builder.
Step 2: Of his Rs. 65 lakh gain, he had used Rs. 35 lakhs. Remaining unutilised: Rs. 30 lakhs.
Step 3: On 20 July 2026, he visited his SBI branch and opened a CGAS Type B account, depositing Rs. 30 lakhs as a 24-month term deposit at 6.5% interest.
Step 4: He files ITR-2 for AY 2026-27, reporting full LTCG of Rs. 65 lakhs and claiming Section 54 exemption: Rs. 35 lakhs used plus Rs. 30 lakhs in CGAS.
Step 5: In April 2027, when the new flat is registered, he submits Form C at the SBI branch, attaches the registration documents, and withdraws the Rs. 30 lakhs (plus accrued interest) to pay the builder.
Step 6: He closes the CGAS account after obtaining an NoC from his Assessing Officer. His full Section 54 exemption holds and zero LTCG tax is paid.
What to do this week
- If you sold a property in the last 12 months and plan to reinvest, count how much of the gain is still unutilised.
- Identify a public sector bank branch near you that operates CGAS and check their list of accepted documents.
- Decide between Type A (liquidity) and Type B (better interest rate) based on when you expect to use the funds.
- Mark the CGAS deposit deadline (your ITR due date) on your calendar with at least a 2-week buffer.

FAQ
Can I open a CGAS account at HDFC or ICICI?
No. Only public sector banks notified by the Central Government can operate CGAS accounts. Private banks are not authorised, even if they serve as your regular bank.
What is the interest rate on Type A versus Type B?
Type A pays at the prevailing savings rate (around 2.5-3% currently). Type B is treated as a fixed deposit and earns the bank's term deposit rate (5.5-7% depending on tenure). TDS rules for fixed deposits apply to Type B interest.
Can I convert Type A to Type B or vice versa?
Yes, you can convert between types within the same account by giving a written request to the branch. The conversion does not affect the underlying exemption status.
What if I move cities during the CGAS period?
You can request a transfer of the CGAS account to a branch of the same bank in your new city. Inter-bank transfer is not allowed; you would have to close the account and reopen in a new bank, which is administratively difficult.
What happens if I die before completing the reinvestment?
The CGAS balance is transferred to the legal heir, and the heir must complete the reinvestment within the remaining period. If the heir does not utilise it, the unused balance becomes taxable in their hands as LTCG in the year the period expires.
Can I claim Section 54EC exemption using CGAS?
No. Section 54EC requires actual investment in NHAI/REC/PFC/IRFC bonds within six months. CGAS is not a route for Section 54EC. CGAS applies to Sections 54, 54B, 54D, 54F, and 54G only.
Can a CGAS deposit be used as collateral for a loan?
No. CGAS deposits cannot be pledged, mortgaged, or used as collateral. The Scheme's terms restrict their alienation until the exemption is realised through actual reinvestment.
