Buying a Bengaluru Site at the BDA Auction, the TDS and Registration Costs You Must Budget

Winning a BDA site at auction feels like the hard part is over. Then the statutory bill arrives, and buyers who budgeted only for the bid discover that stamp duty, registration and tax deducted at source add up fast, and they are due on a tight clock. With the Bangalore Development Authority running its e-auction of about 75 sites from 11 May 2026, getting this math right before you bid is the difference between a smooth registration and a scramble.

The short answer. A BDA auction win in urban Bengaluru carries roughly 7.5 to 7.6 percent in combined statutory cost, made up of slab-based stamp duty, the 2 percent registration fee raised from 1 percent on 31 August 2025, and cess or surcharge, plus a 1 percent tax deducted at source on any property above Rs 50 lakh. Crucially, stamp duty is charged on the higher of your winning bid or the guidance value, so a competitive bid raises your tax base. Stamp duty and registration qualify for Section 80C up to Rs 1.5 lakh.

What taxes apply when I win a BDA site?

Three distinct charges apply. First, stamp duty, a state levy on the transfer document, charged on a slab basis. Second, the registration fee, which Karnataka raised to 2 percent from 1 percent with effect from 31 August 2025. Third, a 1 percent tax deducted at source under the income-tax rules on property purchases above Rs 50 lakh, which the buyer deducts and deposits against the seller's account. On top of stamp duty sit cess and surcharge components, which is why the effective rate runs above the headline stamp-duty number.

How much is stamp duty and registration in 2026?

According to a 2026 cost guide published by Godrej Properties, Karnataka stamp duty is structured in slabs, with higher-value properties attracting up to 5 percent, and lower-value bands attracting 2 or 3 percent. Layered with the 2 percent registration fee and cess or surcharge, the combined statutory cost in urban Bengaluru works out to roughly 7.5 to 7.6 percent of the chargeable value. These are secondary-source summaries of the rate structure, so confirm the exact slab applicable to your site value on the Kaveri 2.0 portal before you finalise your numbers.

When and how do I deduct 1 percent TDS?

If the consideration exceeds Rs 50 lakh, the buyer must deduct 1 percent as tax deducted at source under Section 194-IA and deposit it against the seller's PAN, filing the prescribed form, currently Form 26QB. This is a buyer obligation, not the seller's, and getting it wrong can create compliance headaches later. Reserve this 1 percent in cash separately, because it is over and above your bid and your stamp-duty and registration outlay. Verify the current procedure and threshold before registering, since tax rules are periodically revised.

Is the tax on my bid or the guidance value?

This is the point most auction buyers miss. Stamp duty and registration are charged on the higher of your winning bid or the guidance value for that site. In a competitive auction, your bid can climb well above the guidance value, and when it does, your tax base climbs with it. That means the more aggressively you bid, the more you pay not just in price but in statutory charges. Check the guidance value on Kaveri 2.0 before the auction, and factor the tax consequence into the maximum bid you are willing to place.

Can I claim any deduction?

Yes, within limits. Stamp duty and registration charges paid on a property qualify for deduction under Section 80C of the income-tax rules, subject to the overall annual ceiling of Rs 1.5 lakh that Section 80C shares with other eligible investments. This is a one-time deduction in the year of payment, so keep the official receipts safely. It does not change the cash you pay at registration, but it can reduce your tax for that year if you have headroom under the 80C limit.

How do I pay through Kaveri 2.0?

Karnataka's Kaveri 2.0 portal is the system for stamp-duty and registration payment and appointment booking. Use it to check the guidance value for your site before bidding, compute the duty on the higher of bid or guidance value, and pay the charges as part of the registration workflow. Because the BDA timeline requires 25 percent of the bid within about 72 hours and the balance within roughly 45 days, line up your payment mechanics in advance so the statutory charges do not become a bottleneck at registration.

4. File the tax via Form 26QB against the seller's PAN.
5. Keep stamp-duty and registration receipts for the Section 80C claim.

7. Align payments with the 72-hour and 45-day BDA deadlines.

Frequently asked questions

What is the total statutory cost on a BDA site?

Roughly 7.5 to 7.6 percent in urban Bengaluru, combining slab-based stamp duty, the 2 percent registration fee and cess or surcharge, plus a 1 percent tax deducted at source on properties above Rs 50 lakh. Budget this as cash on top of your winning bid, since it is not financed.

Is tax charged on my bid or the guidance value?

On the higher of the two. Stamp duty and registration are charged on the winning bid value or the guidance value, whichever is greater, so a high winning bid raises your tax base. Check the guidance value on Kaveri 2.0 before deciding your maximum bid.

Can I claim any deduction?

Yes. Stamp duty and registration charges qualify for deduction under Section 80C, subject to the overall Rs 1.5 lakh annual limit and the prevailing rules. Keep the official receipts, since you will need them to claim the deduction when filing your return.

How do I pay the 1 percent TDS?

Deduct 1 percent of the consideration if it exceeds Rs 50 lakh, and file the required form, currently Form 26QB, depositing the amount against the seller's PAN. Verify the current procedure and thresholds before registering, since tax rules can change.
