A ₹1 crore flat never costs ₹1 crore

A ₹1 crore flat touches five distinct tax codes: Stamp duty goes to the state government. GST taxes civil construction. TDS withholds the seller’s income tax. Municipal property tax funds roads and drainage. Capital gains taxes your eventual sale profit.

We organize them into three operational buckets: Acquisition costs that add to the price (GST, stamp duty, registration); Withholding compliance that diverts seller money to the IT department (1% purchase TDS); and Income tax that arrives because you earned rent or realized a gain.

• Transaction cost: GST, stamp duty, registration fees, and municipal tax.
• Statutory withholding: 1% TDS deducted from seller payment above ₹50L.
• Income taxation: Rental income deductions and long-term capital gains.
• Income-tax Act 2025 framework: Form 141 filing within 30 days of deduction.

Rohan earns ₹18 lakh and books a ₹80 lakh flat still being built. Three questions govern his real liability: Is it under construction? What does the state charge for stamp duty? Does Section 194-IA TDS apply?

Under construction implies 5 percent GST without input tax credit (₹4 lakh here). It drops to 1 percent if the flat qualifies as affordable (₹45 lakh with 60 sq m metro carpet). Completed sales with OC carry zero GST. Stamp duty sits apart at 5% to 7% depending on municipality and buyer gender.

TDS is never an additional expense: On a ₹1 crore agreement, you remit ₹99 lakh to the seller and ₹1 lakh directly to the central government. The threshold is ₹50 lakh on the higher of agreement consideration and ready reckoner stamp value.

• GST: 1% affordable, 5% standard under-construction, ₹0 on OC completed sales.
• TDS: 1% on higher of agreement value and circle rate value above ₹50 lakh.
• NRI sellers require separate Section 195 withholding under capital gains slabs.
• File Form 141 within 30 days of the deduction month-end.

The government benchmark rate (known variously as Ready Reckoner, Circle Rate, or Guidance Value) sets mandatory floors everywhere. It determines minimum stamp duty, sets the TDS threshold baseline, and can reset deemed capital gains for the seller and deemed taxable income for the buyer.

If an agreement is signed at ₹60 lakh against an official ready reckoner value of ₹80 lakh, a ₹20 lakh discrepancy arises. Beyond the permitted 10% tolerance band, the seller is taxed on deemed consideration of ₹80 lakh and the buyer faces Section 56(2)(x) income tax on the ₹20 lakh difference. Always check the government reckoner value before finalizing deal terms.

Meera takes possession and rents out her apartment. Municipal property tax is an annual local fee based on built-up area, zone, and age. Group it alongside maintenance and repairs, not transaction taxes.

Her ₹50,000 monthly rent produces ₹6,00,000 in gross annual rent. Gross rent is not taxable rent: Subtract municipal property taxes paid, deduct a flat 30 percent statutory standard deduction on the remainder, and then deduct eligible home loan interest. Tenants deduct 2% TDS only when monthly rent exceeds ₹50,000 to a resident landlord.

Home loan tax deductions depend on regime selection: The old tax regime permits Section 24(b) interest deduction up to ₹2 lakh on self-occupied property, plus Section 80C principal repayment up to ₹1.5 lakh.

• Rental calculation: Gross rent − municipal taxes − 30% standard deduction − loan interest.
• Tenant TDS: 2% threshold applies above ₹50,000/month to resident landlords.
• Loan deductions require checking new vs old tax regime optimization.

Ten years later Rohan sells the flat. The price doubled, but taxable capital gains do not simply double: Acquisition costs, indexed basis options, transfer brokerage, and holding periods determine the taxable amount.

Residential property becomes long-term after 24 months. Long-term sales from 23 July 2024 face a 12.5% rate without indexation. For properties acquired before that date by resident individuals or HUFs, taxpayers can compute tax under 20% with indexation or 12.5% without indexation and pay the lower sum.

Reinvestment windows provide complete relief: Invest capital gains into another residential property within 2 years (or 3 years for construction), or invest up to ₹50 lakh into Section 54EC capital gains bonds within 6 months.

• Long-term holding period: 24+ months at 12.5% without indexation.
• Legacy grandfathering: Pre-23 July 2024 purchases compare 20% indexed vs 12.5%.
• Section 54 reinvestment: 2 years to buy, 3 years to construct, 6 months for 54EC bonds.
• Intra-family gifts may be income-tax exempt but still require state stamp duty.
