Capital Gains Tax on Property Sale in Tamil Nadu: Complete Guide 2026

Property held for more than 2 years attracts long-term capital gains tax at 12.5% without indexation, plus 4% cess, for sales on or after 23 July 2024. Resident individuals and HUFs selling property acquired before 23 July 2024 may instead compute 20% with indexation and pay whichever is lower. Shorter holdings are taxed at slab rates; Sections 54, 54EC, and 54F can exempt the gain, and buyers must deduct 1% TDS above ₹50 lakh.

Long-term vs short-term — how is your property gain classified?

Capital gains tax on property depends on how long you held the property before selling it. The holding period threshold for immovable property in India is 2 years (reduced from 3 years in Budget 2017).

Calculating the gain: • Sale price minus cost of acquisition and cost of improvement = capital gain • For LTCG, the cost of acquisition is indexed using the Cost Inflation Index (CII) to adjust for inflation • Expenses on sale (brokerage, stamp duty on the new purchase, legal fees) are also deductible

If you are a resident individual or HUF and the property was acquired before 23 July 2024, always calculate both routes (20% with indexation vs 12.5% without) before filing and pay the lower. For property acquired on or after 23 July 2024 — and for companies, firms, and non-residents — only the 12.5% no-indexation rate applies. Not sure what your property would actually fetch?

How is the LTCG tax actually computed? A worked example

Understanding the exact tax computation prevents surprises at the time of filing. Long-Term Capital Gains (held more than 2 years): • Default rate for sales on or after 23 July 2024: 12.5% on the unindexed gain (Finance (No. 2) Act, 2024) • Grandfathering option: resident individuals and HUFs selling land or a building acquired BEFORE 23 July 2024 may also compute tax at 20% on the indexed gain and pay whichever of the two is lower • Plus 4% health and education cess on the tax amount • Surcharge applies for very high income levels (above ₹50 lakh total income) Short-Term Capital Gains (held 2 years or less): • Added to your total income and taxed at your applicable slab rate • 4% cess applies • No indexation benefit available for STCG

LTCG computation example (resident individual, property acquired before 23 July 2024 — so both routes are available): • Purchase price (2015): ₹40,00,000 • CII for 2015-16: 254; CII for 2025-26: 376 • Indexed cost: ₹40,00,000 × (376 ÷ 254) = ₹59,21,260 • Sale price (FY 2025-26): ₹85,00,000 • LTCG (indexed): ₹85,00,000 - ₹59,21,260 = ₹25,78,740 • Tax (20%): ₹5,15,748 + cess ₹20,630 = ₹5,36,378 Without indexation at 12.5%: gain = ₹45,00,000; tax = ₹5,62,500 + cess ₹22,500 = ₹5,85,000. Here the indexation route saves ₹48,622 — but the answer flips for recent purchases with steep appreciation, so always compute both. The CII for each year is published by the Income Tax Department at incometaxindia.gov.in (CII for FY 2025-26 is 376 per CBDT Notification 70/2025; the FY 2026-27 index had not been notified as of July 2026).

Section 54 — how do you avoid tax by reinvesting in a house?

Section 54 is the most commonly used capital gains exemption for property sellers in Tamil Nadu. It allows you to avoid LTCG tax entirely if you reinvest the gains in a new residential property.

Key conditions for the Section 54 exemption: • The property sold must be a long-term capital asset (held more than 2 years) • The seller must be an individual or HUF (not a company or firm) • You must purchase one new residential house in India • Purchase: within 1 year before OR 2 years after the date of sale • Construction: within 3 years of the date of sale • The new property must not be sold within 3 years of purchase — if sold earlier, the exemption is reversed and added back as LTCG in the year of sale

Amount of exemption: • Exempt amount = lower of the LTCG amount or the cost of the new property • If the new property costs more than the LTCG, the entire LTCG is exempt • If LTCG is ₹25 lakh and the new property costs ₹20 lakh, only ₹20 lakh is exempt — you pay tax on the remaining ₹5 lakh • Since Budget 2023, the new-house cost counted for the Section 54 (and 54F) exemption is capped at ₹10 crore Remember to budget stamp duty and registration on the reinvestment purchase — estimate it with the stamp duty calculator; these charges form part of the cost of the new house for the exemption.

Section 54EC — what if you invest in capital gains bonds instead?

Section 54EC offers an alternative exemption route — instead of buying another property, you invest the capital gains in specified bonds. This is ideal for sellers who do not want to buy another property. Eligible bonds (2026): • REC (Rural Electrification Corporation) bonds • PFC (Power Finance Corporation) bonds • IRFC (Indian Railway Finance Corporation) bonds • All are AAA-rated public-sector issuers; NHAI discontinued its 54EC bond issue in 2022 and no longer accepts fresh investments

Key conditions: • Investment must be made within 6 months of the property sale date • Maximum investment: ₹50,00,000 per financial year (not per transaction — the annual cap applies) • Lock-in period: 5 years — you cannot redeem, pledge, or sell these bonds before 5 years • If redeemed or transferred within 5 years, the exemption is withdrawn and the LTCG becomes taxable in that year

Tax treatment of the bonds: • The bonds earn a fixed interest rate (around 5.25–6% p.a. — confirm the prevailing coupon in the issuer's current information memorandum before investing) • Interest income from these bonds is fully taxable as per your income slab • There is no TDS on these bonds if you submit Form 15G/H

Section 54F — selling a plot, shop, or other non-residential asset?

Section 54F provides capital gains exemption when you sell a non-residential long-term asset (such as commercial property, agricultural land, or gold) and reinvest the proceeds in a residential house. Key differences from Section 54: • Section 54 applies to gains from selling a residential property and buying another residential property • Section 54F applies to gains from selling ANY long-term capital asset (other than residential property) — commercial plot, shop, agricultural land, jewellery, shares, etc. • Under 54F, the exemption is proportional: you must invest the entire net sale consideration (not just the gain) in the new residential property to claim full exemption

Conditions for Section 54F: • The seller must be an individual or HUF • The long-term asset sold must not be a residential house • The new residential property must be purchased 1 year before or 2 years after the sale, OR constructed within 3 years • On the date of sale, the seller must not own more than 1 residential house (other than the one being purchased) • The new property must not be sold within 3 years

Proportional exemption formula: Exempt LTCG = LTCG × (Cost of new house ÷ Net sale consideration) Example: agricultural land sold for ₹80 lakh, LTCG = ₹30 lakh. New house purchased for ₹60 lakh. Exempt LTCG = ₹30 lakh × (₹60 lakh ÷ ₹80 lakh) = ₹22.5 lakh. Tax on the remaining ₹7.5 lakh at 12.5% = ₹93,750 (plus cess). For full exemption: invest the entire ₹80 lakh (full sale proceeds) in the new house.

TDS on property sale — what must the buyer deduct?

When buying a property valued above ₹50 lakh, the buyer is legally required to deduct 1% TDS (Tax Deducted at Source) under Section 194-IA from the payment to the seller and deposit it with the government. This applies to both resident and NRI sellers (different rates for NRIs). Applicability: • Property value above ₹50 lakh — TDS applies on the entire amount, not just the excess over ₹50 lakh; the ₹50 lakh threshold applies to the total consideration even when there are multiple buyers or sellers • TDS is computed on the higher of the sale consideration or the stamp duty value • Applies to all property types: residential, commercial, and plots • Does not apply to agricultural land TDS rate: • Resident seller: 1% of the total sale consideration • NRI seller: TDS under Section 195 at 12.5% plus surcharge and cess on long-term gains for sales on or after 23 July 2024 (covered separately in the NRI guide). Estimate NRI TDS and repatriation with AVnester's tax regime optimizer.

How does the indexation benefit work?

Indexation adjusts your property's purchase cost for inflation, significantly reducing your taxable capital gain. The government publishes the Cost Inflation Index (CII) for each financial year, with 2001-02 as the base year (CII = 100). Since 23 July 2024, indexation survives only inside the optional 20% route — available to resident individuals and HUFs for land or buildings acquired before that date. Indexed cost formula: Indexed Cost of Acquisition = Purchase Price × (CII of sale year ÷ CII of purchase year)

Worked example — Coimbatore property (acquired well before 23 July 2024, resident individual, so both routes apply): • Plot purchased in 2010 for ₹15,00,000 (CII 2010-11: 167) • Villa constructed in 2014 for ₹25,00,000 (CII 2014-15: 240) • Property sold in FY 2025-26 for ₹1,20,00,000 (CII 2025-26: 376) Indexed cost of plot: ₹15,00,000 × (376 ÷ 167) = ₹33,77,246 Indexed cost of construction: ₹25,00,000 × (376 ÷ 240) = ₹39,16,667 Total indexed cost: ₹72,93,913 LTCG: ₹1,20,00,000 - ₹72,93,913 = ₹47,06,087 Tax at 20%: ₹9,41,217 Without indexation (12.5% rate): Gain: ₹1,20,00,000 - ₹40,00,000 = ₹80,00,000; tax: ₹10,00,000 Here indexation (the 20% route) saves ₹58,783. Always compute both to find the lower liability.

What about inherited or gifted property?

Property received through inheritance or gift has special rules for computing capital gains when you eventually sell it. Inherited property: • Inheritance is NOT a transfer under the Income Tax Act — no capital gains tax when you inherit • When you sell inherited property, the gain is computed based on the ORIGINAL purchase cost of the deceased (not the value at the time of inheritance) • The holding period includes the period held by the deceased — so property held for decades by your parent is already long-term in your hands • Cost of acquisition = the price the deceased originally paid (or the Fair Market Value as of April 1, 2001 if purchased before 2001 — you can take the higher of the two)

Gifted property: • Gifts between specified relatives (spouse, parents, siblings, children, etc.) are not taxable in the recipient's hands • When the recipient sells, capital gains are computed the same way as inherited property — using the original donor's cost and original purchase date • Gift from non-relatives: the Fair Market Value at the time of gifting is treated as income and taxed in the recipient's hands at the time of receiving; when sold, the cost of acquisition becomes this FMV
