The Real Cost of Buying a Flat in Bengaluru (2026): Stamp Duty, the 2% Registration Fee, GST

Last updated 16 July 2026 · Facts checked against the sources listed at the end

The brochure quotes one number. The cheques add up to a larger one, by a margin that is mostly statutory and fully predictable. This guide works through every government line on a Bengaluru flat purchase in 2026 (stamp duty, cess, surcharge, the doubled registration fee, GST, TDS) and the khata paperwork that decides whether your sale deed gets registered at all.

What are Karnataka’s stamp duty and registration charges in 2026?

For a flat above ₹45 lakh (which in practice means every apartment in North Bengaluru), Karnataka levies 5% stamp duty, a cess of 10% of that duty, a surcharge of 2% of the duty inside BBMP limits (3% in gram-panchayat areas), and a registration fee of 2% of the property value. Stacked, the government’s take is about 7.6% of the deal value in urban Bengaluru.

The slabs sit below that headline rate only for small tickets: 3% stamp duty between ₹21 lakh and ₹45 lakh, and 2% up to ₹20 lakh, per ClearTax’s 2026 Karnataka guide. Rates are uniform across the state, and Karnataka offers no gender-based concession on duty.

The line that changed recently is registration. Karnataka doubled the registration fee from 1% to 2% of property value with effect from 31 August 2025. It was the first revision since 2003, as Propsoch reported when the change was announced. The higher fee applies not just to sale deeds but also to agreements to sell, lease agreements and mortgage registrations. Arithmetically, that moved the total government charge on an above-₹45 lakh urban flat from roughly 6.6% to about 7.6%: an extra percentage point on every registered sale.

Two mechanics trip up first-time buyers. The cess and the surcharge are computed on the stamp-duty amount, not on the property value, a distinction cost sheets often blur; Godrej Capital’s guide sets the stack out correctly. And the urban–rural gap is smaller than folklore suggests: 5.60% versus 5.65% effective duty, or ₹7,000 on a ₹1.4 crore flat. Jurisdiction matters far more for khata paperwork, covered below.

What do government charges come to on a ₹1.4 crore flat?

₹10,64,000 (call it ₹10.64 lakh, or 7.6% of the price) on a ₹1.4 crore flat registered inside BBMP limits. At ₹1.5 crore the same stack reaches ₹11.40 lakh. Register the identical flat in a gram-panchayat jurisdiction and the bill rises by only ₹7,000, to ₹10.71 lakh.

Computed on the sale value; duty is levied on the higher of agreement value and guidance value. Nominal scanning and e-service fees extra. Rate structure per ClearTax and Godrej Capital guides to Karnataka charges, as of July 2026.

Treat 7.6% as the planning number, applied to the higher of your agreement value or the guidance value, and remember it is paid upfront at registration. Kaveri 2.0 computes the exact figure for your document; confirm it with the jurisdictional sub-registrar before you lock a date.

Does GST apply to your purchase, and did GST 2.0 change anything?

If you buy under construction and the flat costs more than ₹45 lakh, add 5% GST with no input-tax credit: ₹7 lakh on a ₹1.4 crore home. Affordable units, up to ₹45 lakh within carpet-area caps, attract 1%. A ready-to-move flat whose Occupancy Certificate has been issued attracts no GST at all. The September 2025 “GST 2.0” overhaul left all three buyer-side rates untouched.

The 0% line is about timing, not just inventory choice. GST applies to instalments paid before the OC is issued; instalments falling due after the OC sit outside GST, as NoBroker’s comparison guide sets out. The 1%/5%-without-credit regime has been in force since April 2019 and is confirmed as current by 2026 guides, including Razorpay’s.

What GST 2.0 (the 56th Council’s two-slab structure, effective 22 September 2025) changed is the input side: cement dropped from 28% to 18% GST, reported by Business Standard on 4 September 2025. CREDAI welcomed the cut the same day, estimating direct savings of ₹12–15 per sq ft in construction cost; Anarock and CBRE suggested a possible 2–5% price correction if developers pass the benefit through.

GST turns entirely on your payment schedule relative to the OC date. Before you sign a construction agreement, have your CA confirm the treatment of each instalment.

Which guidance value applies in July 2026, old or revised?

The old values, per the most recent reporting available. Karnataka’s Department of Stamps and Registration announced an upward revision (about 10–15% statewide) on 14 April 2026, but it had not been gazette-notified as of late-June 2026 reporting, so the earlier guidance values remained legally operative. That status can change in any given week; check igr.karnataka.gov.in before you register.

Guidance value matters because stamp duty and registration fee are charged on the higher of your declared agreement value and the guidance value for the property. The Kaveri 2.0 portal applies the higher figure automatically when computing your duty. If the revision is notified and the guidance value overtakes your agreement value, your 7.6% is computed on the larger base.

Zone-wise, the revision was reported at roughly 12% in central zones and up to 35% in peripheral ones. If notified in that shape, it lands hardest on the city’s growth fringes, North Bengaluru included. Treat the splits as reported, not final; notification had been anticipated around June–July 2026.

The timing rule is the practical takeaway: the value table in force on the date of registration applies, not your agreement date, and registrations completed before a notification stand valid at the old values, per PropNewz’s May 2026 buyer playbook. Sign this month and register after a notification lands, and your duty base may rise in between. Budget for that gap, and re-confirm the operative table with the sub-registrar in the week you register.

Is e-khata mandatory to register a flat now?

Yes. Inside BBMP/Greater Bengaluru limits, Kaveri 2.0 will not process a sale deed without a verified e-khata reference number drawn from the e-Aasthi system. The requirement arrived in phases (property registrations from 1 October 2024, BBMP-wide approvals from 1 July 2025, khata conversions from 1 November 2025) and is now simply how registration works.

Build the paperwork into your timeline rather than discovering it at the sub-registrar’s office. Digitising an existing A-khata into e-khata runs about 7–14 working days, and a fresh e-khata roughly 14–30 working days, per 2026 guides. Ask the seller or developer for the e-khata extract before you pay any token amount.

Two 2026-specific wrinkles. For B-khata properties, the conversion charge to A-khata drops from 5% to 2% of guidance value for a 100-day window running 15 May to 23 August 2026, per NoBroker’s coverage, with about five weeks left as this piece goes up. And outside BBMP limits (much of the Sathanur–Bagalur belt along the airport corridor), the documents differ: gram-panchayat properties run on e-Swathu, where Form 9 (the property record) and Form 11 (the demand-register extract) are mandatory for registration, per the official district services listing. Since e-Swathu 2.0 went live in late 2025, both forms issue only after GPS geo-referencing ties the record to the physical plot.

The question to ask of any project: which khata regime does this survey number fall under, and can you show me the current extract? If the answer is vague, the jurisdictional sub-registrar’s office can tell you exactly what it will demand.

What is the 1% TDS a buyer must deduct above ₹50 lakh?

Where the sale consideration or the stamp-duty value is ₹50 lakh or more, the buyer must deduct 1% tax at source, computed on the higher of the two, and deposit it against the seller’s PAN. The provision is Section 194-IA of the 1961 Act, now Section 393(1) of the Income-tax Act 2025, effective 1 April 2026. Practically every North Bengaluru apartment crosses the threshold, so treat this as a standard step, not an edge case.

The mechanics are deliberately light: no TAN is required (the buyer’s PAN suffices), and rural agricultural land sits outside the net, per TDSMAN’s May 2026 explainer. The filing changed with the new Act: Form 26QB served until 31 March 2026; transactions on or after 1 April 2026 file Form 141. On a ₹1.4 crore flat the deduction is ₹1.4 lakh: not an extra cost, since it comes out of the agreed price, but a compliance duty that sits on you, the buyer, with interest and penalties for missing it.

One boundary worth flagging: all of this assumes a resident seller. Buying from an NRI seller triggers a different provision (TDS on the entire consideration at capital-gains-linked rates), ground our NRI guide covers in detail. The TDS procedure has changed twice in two years; confirm the current form and rate with your CA before the first payment leaves your account.

What else lands on the developer’s cost sheet?

Beyond taxes, a primary-sale cost sheet typically itemises preferential location charges, floor-rise charges, covered car parking, clubhouse membership, corpus fund contributions, maintenance advances, and legal or khata-transfer charges. None of these are statutory, their pricing varies project to project, and most are billed with GST on top as services. The discipline that protects you is simple: itemise the cost sheet line by line before signing anything.

These are the “hidden charges” buyers search for, except they are not hidden once you insist on the full cost sheet. Ask which lines carry GST and at what rate, so the quoted figure is genuinely all-in. Distinguish the corpus fund (a reserve that notionally stays with the future owners’ association) from maintenance advances, which are consumed from day one. Ask what happens to each line if you exit before registration. We have deliberately not quoted typical percentages here: these charges are set by each developer, not by law, and any average would mislead.

When you request pricing, ask for the full cost sheet rather than the base rate. If you are evaluating TVS Emerald Altura, you can request the current cost sheet and read these lines yourself.

What does a ₹1.4 crore flat actually cost, all-in?

About ₹1.58 crore before a single developer extra: ₹1.4 crore of base price, ₹7 lakh of GST if bought under construction, and ₹10.64 lakh of stamp duty, cess, surcharge and registration. That is 12.6% above the sticker. Buy ready-to-move with an OC and the GST leg falls away, leaving the government add-on at about 7.6%.

Indicative stack on a BBMP-area, under-construction purchase at ₹1.4 crore, July 2026. Each levy has its own base: GST on the sale consideration, duty on the higher of agreement and guidance value. Developer cost-sheet items (PLC, parking, corpus, advances) sit on top. Verify line by line.

Two closing disciplines. Compare projects on this all-in number, never the brochure rate. Our North Bengaluru price tracker and the under-₹2 crore shortlist label base versus all-in figures for exactly this reason. And run the document checks yourself before money moves.
