A widespread misconception exists that capital gains tax remains deferred until funds are physically withdrawn from the Capital Gains Account Scheme (CGAS) account. However, statutory tax provisions offer no such flexibility. Under Sections 54 and 54F of the Income-Tax Act, 1961, exemptions are conditional and if money deposited in a CGAS account remains unutilised for buying or constructing a new home, the tax shelter expires automatically. Taxability kicks in precisely three years after the original long-term asset's transfer date—regardless of whether the original asset was a residential property (Section 54) or a non-residential asset (Section 54F). Consequently, unutilised balances become taxable right when that three-year window closes, even if the money stays locked in the bank. As per Economic Times, many taxpayers who claimed exemption under Sections 54 and 54F in earlier assessment years receive income tax notices because they overlook the three-year rule governing the Capital Gains Account Scheme.
Both provisions offer tax relief for reinvesting in residential property, but under different metrics. Section 54 applies to long-term gains from selling a residential house, requiring the capital gains to be reinvested. Section 54F applies to long-term gains from selling non-residential assets, requiring the net sale consideration (total proceeds minus selling expenses) to be reinvested. Since property acquisitions often take time, buyers frequently miss the standard tax return filing deadline under Section 139(1). To protect the taxpayer's exemption, the law allows unspent amounts to be parked in an official CGAS account before filing. Deposited funds count as temporary 'deemed investments,' preserving the tax exemption provided they are deployed within the statutory period. Under Section 54, the unutilised capital gains are required to be deposited, while under Section 54F, the unutilised net sale consideration (full value of consideration minus expenses connected with the transfer) is required to be deposited.
The tax rules permit strategic timing for property purchases and construction projects. The tax department allows the purchase of a home up to one year before the sale of the existing property or within two years after the transaction. For those opting to build a new residential house, construction must be finished within three years of selling the original property. When claiming exemption under Section 54 by buying or constructing a new house, you must hold the property for at least three years. If you sell it before the three-year period ends, the exemption is withdrawn and the exempted capital gains are added back by reducing the property's cost of acquisition, increasing the taxable gain on the second sale. This rule is designed to prevent taxpayers from repeatedly deferring capital gains tax through frequent property transactions.
With the Assessment Year 2026–27 filing deadline fast approaching, anyone who previously claimed these exemptions must evaluate their past CGAS deposits to report any newly taxable gains. Taxpayers frequently overlook this nuance when filing subsequent returns. The law allows unspent amounts to be parked in an official CGAS account before filing to protect the exemption, but the three-year statutory period remains absolute regardless of whether the money remains in the account or is withdrawn. This means that even if funds are still deposited in the CGAS account after the three-year period, they become taxable once the deadline passes. With the Income Tax Department increasingly relying on data analytics to identify inconsistencies across assessment years, taxpayers should look beyond the current year's transactions while filing their returns. A simple review of capital gains exemptions claimed in earlier years can help taxpayers avoid unnecessary tax liability, interest, penalties and prolonged litigation.
