📌 Quick Answer
If you sold or bought property in FY 2024-25, you must report capital gains in your ITR by the due date. Common ITR mistakes on property sale include filing the wrong form (ITR-1 instead of ITR-2), skipping the CGAS deposit, missing the indexation choice, and not filling Schedule CG. Each error can attract a tax notice, a penalty of up to 300%, or the loss of valuable exemptions under Section 54 or 54F.
Selling or buying a house feels like the finish line. You sign the papers, transfer the money, and breathe a sigh of relief. For thousands of Indian taxpayers, however, the real challenge begins during ITR filing. Even a single reporting mistake in a property transaction can trigger a tax notice, wipe out a valid exemption worth lakhs, or result in a penalty ranging from 100% to 300% of the tax evaded.
How the Tax Department Already Knows About Your Property Transaction
The stakes are especially high for FY 2024-25 (AY 2025-26) because capital gains rules changed mid-year. In addition, property sale information flows directly to the Income Tax Department through stamp duty records, Form 26QB filings, and the Annual Information Statement (AIS). As a result, the department already has visibility into your transaction whether you report it correctly or not.
Why Property Sale ITR Filing Is Trickier Than Ever in 2025–26
Union Budget 2024 introduced a major change effective 23 July 2024: the Long-Term Capital Gains (LTCG) tax rate on property dropped from 20% to 12.5%, while indexation benefits were removed for properties acquired after that date. Consequently, sellers now face a dual-option regime based on their purchase date. Choosing the wrong option can significantly increase the tax payable.
[KEEP THE TABLE EXACTLY AS IT IS]
This flexibility is genuinely valuable, but only when applied correctly in your ITR filing. A wrong calculation can cost lakhs through unnecessary tax payments or missed exemptions.
Mistake 1 — Filing ITR-1 or ITR-4 Instead of ITR-2
This is the most dangerous ITR mistake on a property sale, yet it happens every season. If you have any capital gains — short-term or long-term — you cannot use ITR-1 (Sahaj) or ITR-4 (Sugam). Instead, you must file ITR-2 (or ITR-3 if you also have business income). Filing the wrong form means your return is technically defective, which can trigger a notice and delay your refund.
⚠️ Fix: Check your AIS on the Income Tax Portal before filing. If any property transaction appears there, switch to ITR-2 immediately.
Mistake 2 — Skipping Schedule CG Entirely
Many salaried taxpayers assume their employer’s Form 16 covers everything. However, capital gains have a separate reporting requirement in the ITR. Schedule CG must be filled with the sale price, indexed cost of acquisition, transfer expenses, reinvestment details, and CGAS deposit information (if applicable). Leaving Schedule CG blank while the department’s AIS already shows a property transaction is a direct invitation for scrutiny.
Mistake 3 — Missing the CGAS Deposit Deadline
If you have sold a property and plan to reinvest the gains under Section 54 (residential property) or Section 54EC (bonds), but the reinvestment is still pending at the time of filing — you must deposit the uninvested amount in the Capital Gains Account Scheme (CGAS) at an authorised bank before the ITR filing due date. Missing this step means losing the exemption altogether for that financial year.
Additionally, if the CGAS funds remain unused after three years, the amount automatically becomes taxable LTCG in the year the deadline lapses. Therefore, open the account early and plan your reinvestment timeline carefully.
✅ Fix: Open a CGAS account at SBI, PNB, or any authorised bank well before the ITR due date. Keep the deposit receipt; you will need it while filling Schedule CG.
Mistake 4 — Not Choosing Indexation When It Can Save You More
For properties purchased before 23 July 2024, you can choose between paying 20% tax with indexation or 12.5% without indexation. Many taxpayers automatically select the lower-looking 12.5% rate without actually running the numbers. In contrast, a property bought in 2010 and sold in 2025 may show a much smaller indexed gain, making 20% with indexation the cheaper option in rupee terms. Always calculate both scenarios before filing.
Mistake 5 — Misclassifying STCG as LTCG (or Vice Versa)
A property held for less than 24 months generates Short-Term Capital Gain (STCG) and attracts tax according to your applicable income slab. Once the holding period crosses 24 months, the gain qualifies as LTCG. Many taxpayers miscalculate the holding period and report the gain under the wrong category. Such mistakes either increase the tax burden or attract penalties for under-reporting.
Mistake 6 — Ignoring TDS Deducted Under Section 194-IA
When you sell a property worth ₹50 lakh or more, the law requires the buyer to deduct 1% TDS under Section 194-IA and deposit it through Form 26QB. Sellers can view this TDS credit in Form 26AS. Failure to claim the credit results in excess tax payment. On the other hand, if the buyer has not submitted Form 26QB correctly, the credit may not appear and should be followed up before filing the return.
Mistake 7 — Selling the New Property Within 3 Years of Claiming Section 54
Section 54 includes a three-year lock-in period for the replacement property purchased to claim the exemption. Selling the new property before completing that period reverses the benefit. The tax department then treats the previously exempt gain as taxable income in the year of sale. Many investors discover this condition only after receiving an unexpected tax liability.

How the Tax Department Detects Property Sale Reporting Errors
Property sale transactions rank among the most closely monitored transactions by the Income Tax Department. Officers automatically cross-check TDS records, stamp duty filings, and AIS disclosures. Therefore, hiding or under-reporting capital gains rarely goes unnoticed. The consequences include:
• Section 234F: Late filing penalty of ₹5,000 (₹1,000 if total income is below ₹5 lakh)
• Section 234B: Interest at 1% per month on unpaid advance tax
• Section 271(1)(c): Concealment penalty between 100% and 300% of the tax evaded
• Lost CGAS window: Missing the filing deadline permanently removes the option to deposit funds into CGAS for that year, resulting in the loss of the Section 54 exemption
3 Myths About Property Sale and ITR — Busted
❌ Myth: “I reinvested the money, so no tax applies.”
Reality: Claiming a Section 54 or 54F exemption requires more than reinvestment. Taxpayers must also disclose the exemption correctly in Schedule CG before the due date.
❌ Myth: “The buyer deducted TDS, so the tax is already paid.”
Reality: TDS under Section 194-IA serves only as a tax credit. You still need to calculate the actual capital gain, report it in ITR-2, and pay any remaining tax liability.
❌ Myth: “I can file a revised return to add the capital gain later.”
Reality: Although revised returns are permitted, taxpayers cannot restore a missed CGAS deposit opportunity or reclaim a Section 54 exemption after the original deadline expires.
Frequently Asked Questions
Q: Which ITR form should I use if I sold property in FY 2024-25?
Taxpayers reporting capital gains from a property sale must file ITR-2. ITR-1 (Sahaj) and ITR-4 (Sugam) do not contain Schedule CG and therefore cannot report capital gains. Choose ITR-3 only when business or professional income is also involved.
Q: What is the CGAS and why do I need to deposit capital gains in it?
CGAS stands for Capital Gains Account Scheme. Taxpayers planning to claim Section 54 or 54F exemptions must deposit uninvested gains into a CGAS account if they have not yet completed the purchase or construction of the new property before the ITR due date. This step preserves eligibility for the exemption. Any unused balance becomes taxable LTCG after three years.
Q: Should I choose 12.5% without indexation or 20% with indexation?
Only properties purchased before 23 July 2024 qualify for this choice. Calculate the tax liability under both methods and select the lower amount. Long-held properties often benefit more from the 20% with indexation option because inflation adjustment reduces the taxable gain significantly.
