Why Is Your Tax Software Still Computing Indexation? It May Actually Be Saving You Tax
If you have recently sold a plot of land or a building acquired many years ago, you may have noticed something rather puzzling while preparing your Income Tax Return. Your tax software is still calculating the Indexed Cost of Acquisition using the Cost Inflation Index (CII), even though indexation was withdrawn by the Finance (No. 2) Act, 2024 for transfers made on or after 23rd July 2024.
Naturally, many taxpayers wonder: “Has my software not been updated?”
The answer is No. Your software is doing exactly what the law requires.
Indexation is Gone… But Not Completely
The Finance (No. 2) Act, 2024 brought a major overhaul in the taxation of long-term capital gains on land and buildings. For transfers on or after 23rd July 2024, the law generally provides:
Long-Term Capital Gains (LTCG) Tax Rate: 12.5%
Indexation Benefit: Withdrawn
At first glance, it appears that indexation has disappeared altogether.
However, there is an important exception hidden in the Second Proviso to Section 112(1)(a) of the Income-tax Act, 1961.
This proviso preserves indexation—not for computing capital gains—but only for determining the maximum tax payable in certain cases.
Why Your Software Computes Indexation
Suppose a resident individual purchased a plot in 1998 and sold it after 23rd July 2024.
The software performs two separate tax calculations:
Calculation 1 – Under the New Regime
Capital Gain = Sale Price – Actual Cost
Tax = 12.5% of the unindexed gain
Calculation 2 – Under the Protective Provision
Capital Gain = Sale Price – Indexed Cost
Tax = 20% of the indexed gain
The law then compares both tax figures.
If the tax under the old indexed method is lower, the taxpayer is not required to pay the excess tax under the new method.
In other words, the software is not applying indexation to reduce your capital gain. It is using indexation only to ensure that you do not pay more tax than the law permits.
Indexation Now Works Only as a Tax Ceiling
This is perhaps the most important conceptual change introduced by the amendment.
Earlier, indexation reduced the capital gain itself.
Now, indexation merely limits the amount of tax payable.
The capital gain legally remains the unindexed gain.
This distinction may appear technical, but it has significant practical consequences.
Who Gets This Benefit?
The relief is available only to:
Resident Individuals
Hindu Undivided Families (HUFs)
The benefit does not extend to:
Companies
Partnership Firms
LLPs
Trusts
Associations of Persons
Non-Residents, including NRIs
This means that two taxpayers selling identical plots acquired on the same date may pay completely different taxes simply because of the legal form in which the property is held.
For example, a family that transferred ancestral land into an LLP for succession planning will not get this protection, whereas another family member holding similar land personally may continue to enjoy the benefit.
The difference can run into several lakhs of rupees.
The Capital Gain Remains Unindexed
Many taxpayers mistakenly assume that once the indexed computation produces a lower tax, the indexed capital gain also becomes the official capital gain.
That is incorrect.
The law only compares the tax liability.
For every other provision of the Income-tax Act, the capital gain continues to be the unindexed gain.
This affects several important provisions.
For example:
Exemption under Section 54
Exemption under Section 54F
Investment under Section 54EC
Set-off of capital losses
Carry forward of losses
All these continue to be determined with reference to the unindexed capital gain, not the indexed figure.
A Hidden Relief That Many Taxpayers Miss
The software’s indexed computation often surprises taxpayers because they believe indexation has vanished entirely.
In reality, the law has not abolished indexation completely—it has merely changed its role.
Instead of reducing the capital gain, it now functions as a protective mechanism, ensuring that eligible resident individuals and HUFs are not worse off because of the shift to the new 12.5% tax regime.
Final Thoughts
When your tax software displays an indexed cost despite the withdrawal of indexation, it is not following outdated law—it is faithfully implementing one of the most nuanced transitional provisions introduced by the Finance (No. 2) Act, 2024.
The message is simple: Indexation may no longer reduce your capital gains, but for eligible resident individuals and HUFs, it still plays an important role in reducing the tax payable.
So, the next time your software computes both indexed and unindexed gains, don’t assume it has made a mistake. It may actually be ensuring that you pay exactly what the law requires—and not a rupee more.
