Selling a Bengaluru House? How Capital Gains Tax Works (and How to Check It in 2 Minutes)

1. Start with the free calculator, then read this page

If you are selling a flat, site or commercial unit in Bengaluru, the tax question is usually the same: how much of the profit does the government take? Open the PE Realtors Capital Gains Calculator first, then use this article as the plain-English map of what the numbers mean.

The tool is built for Indian residential and commercial property. It uses CBDT Cost Inflation Index values from FY 2001-02 through FY 2026-27, compares the new 12.5% rate with the older 20% indexed rate when you are eligible, adds 4% cess, and lets you download a one-page report. It is a planning tool, not a filed return.

2. Two clocks: how long did you hold it?

Think of two boxes. Hold the property for 24 months or more and the profit is generally long-term capital gains (LTCG). Hold it for less than 24 months and it is short-term (STCG). Short-term gain is added to your other income and taxed at your slab. The calculator uses 30% as a simple stand-in for that slab so you can see a number quickly. Your real slab may be lower or higher.

The tool counts holding time from the purchase financial year to the sale financial year. For filing, a CA will use the exact dates on the sale deed. If you are close to 24 months, do not guess — check the dates.

3. The July 2024 change, in one paragraph

The Income Tax Department’s capital-gains page now states the default clearly: long-term capital gains are taxable at 12.5% without indexation. There is one important door still open. Resident individuals and HUFs who acquired land, a building, or both before 23 July 2024, and transfer it on or after that date, can instead choose 20% with indexation — and pay whichever is lower.

Indexation is just inflation math. The government publishes a Cost Inflation Index (CII) each year. You scale the old purchase price (and any capital improvement) to today’s rupees, so you are not taxed on inflation that was never real profit. CBDT still notifies a fresh CII — including for FY 2026-27 — because that grandfathered 20% option is still in use.

4. What to type into the PE Realtors calculator

Open the PE Realtors Capital Gains Calculator and fill only what you actually have:

• Purchase price — what you paid (or the 1 April 2001 fair value if the property is older than that).
• Sale price — agreement value. If Bengaluru guidance / stamp-duty value is higher, Section 50C can tax you on that higher number. Type the real tax base, not the hopeful one.
• Purchase and sale financial years — the tool loads CII automatically.
• Cost of improvement — only capital work (an extra floor, a structural remodel). Society bills, paint, property tax and home-loan interest usually do not count.
• Selling expenses — brokerage, legal fees, directly tied to the sale.
• 20% indexation option — tick this only if you are a resident individual or HUF and the land/building was acquired before 23 July 2024. The tool then picks the cheaper of 12.5% and 20%.

5. A simple Bengaluru-style example

Suppose you bought at ₹50 lakh in FY 2018-19 and sell at ₹90 lakh in FY 2026-27, with no extra improvement and no brokerage. Gain without indexation is ₹40 lakh. Tax at 12.5% is ₹5 lakh, plus 4% cess, about ₹5.20 lakh. With indexation the same purchase becomes about ₹68.57 lakh in today’s rupees, the gain shrinks to about ₹21.43 lakh, and 20% plus cess is about ₹4.46 lakh. If you are eligible for the old option, the calculator will prefer that lower bill. Type the same figures into the PE Realtors Capital Gains Calculator to see the charts and download the report.

6. How people legally reduce the tax — and what the tool does not do

Three sections come up in almost every Bengaluru sale conversation. Section 54: you sold a residential house and buy or build another house in India (buy one year before or two years after, or construct within three years). Exemption is on the gain you reinvest, with a ₹10 crore cap. Section 54F: you sold something that is not a residential house (a site, a shop) and put the net sale money into one house. Section 54EC: you put up to ₹50 lakh into notified bonds (NHAI, REC and others) within six months. Sell the new house within three years and the exemption can unwind.

The capital-gains calculator does not apply those exemptions automatically. Use it to see the raw tax, then use the Section 54 reinvestment planner on the same tools list if you are buying another home. NRIs should also check TDS and FEMA paperwork separately — the on-screen 12.5% is not the last word for a non-resident seller.

Surcharge (when total income crosses ₹50 lakh) is not inside the calculator. Neither is a 50C stamp-duty uplift. If those apply, the real bill is higher than the screen. Keep the sale deed, payment proofs, improvement invoices and a CA in the loop before you commit the sale proceeds.
