Quick answer: The sticker price of a Bengaluru flat is not what you actually pay. On a ₹1.2 crore flat, the real out-the-door cost is 13-16% higher for a ready-to-move or resale property, and around 18-20% higher for an under-construction one (which attracts 5% GST that ready properties don''t). The unavoidable statutory costs in Karnataka now total about 7.6% of the property value for homes above ₹45 lakh: stamp duty of 5% (plus a 10% cess and 2% surcharge on the duty, taking it to an effective 5.6%) and registration of 2% — the registration fee having doubled from 1% to 2% on 31 August 2025, the first revision since 2003. On top of that come Bengaluru-specific setup costs (khata transfer, BESCOM electricity and BWSSB/Cauvery water deposits) and the under-discussed builder charges that catch buyers off guard: covered car parking (₹2-8 lakh, billed separately), advance maintenance and corpus deposits, clubhouse and amenity charges, and brokerage (1-2% on resale deals). The single biggest swing factor is GST: a ₹1.2 crore ready-to-move flat with an occupancy certificate pays zero GST, while the same flat under construction adds ₹6 lakh in GST. Budget for these costs separately and upfront — home loans fund only the property value, not the stamp duty, registration, or extras, so the entire 13-20% comes out of your own pocket.
Key takeaways
- On a ₹1.2 crore Bengaluru flat, total extra costs add about 13-16% for ready/resale properties and 18-20% for under-construction (which attracts 5% GST).
- Karnataka statutory costs above ₹45 lakh total ~7.6%: stamp duty 5% (effective 5.6% with 10% cess + 2% surcharge) plus registration 2% — the registration fee doubled from 1% to 2% on 31 August 2025.
- GST is the biggest swing: a ready-to-move flat with an occupancy certificate is GST-exempt, while an under-construction flat adds 5% (₹6 lakh on a ₹1.2 crore property).
- The under-discussed costs are car parking (₹2-8 lakh, billed separately and which must be named in your sale agreement), maintenance advance and corpus, clubhouse charges, and resale brokerage (1-2%).
- Home loans fund only the property value, not stamp duty, registration, or extras — so the entire 13-20% comes from your own savings and must be budgeted separately.
Buying a home is the largest financial transaction most families ever make, and in Bengaluru — one of India''s most active property markets — the gap between the advertised price and the amount that actually leaves your bank account routinely surprises first-time buyers. A flat marketed at ₹1.2 crore can end up costing ₹1.35-1.45 crore once every statutory charge, government deposit, builder levy, and transaction cost is added in. None of these are optional extras you can negotiate away entirely; most are mandatory, and the few that are negotiable are rarely waived. This guide breaks down every component of the real cost of buying a home in Bengaluru in 2026, with a complete worked example on a ₹1.2 crore flat, so you can budget for the actual number rather than the sticker price.
Use Ganak''s Stamp Duty Calculator to compute the statutory charges on your specific property value, the Property Tax Calculator for ongoing BBMP tax, and the Home Loan EMI Calculator to plan the financing.
Statutory Costs: Stamp Duty and Registration
These are the unavoidable government charges levied on every property transaction in Karnataka, payable at registration. They''re calculated on the higher of your actual sale price or the government''s guidance value (the minimum notified value for the area) — so if you negotiate a price below the guidance value, you still pay these charges on the guidance value.
Stamp duty in Karnataka follows a slab structure based on property value:
| Property value | Stamp duty rate |
|---|---|
| Below ₹20 lakh | 2% |
| ₹20 lakh to ₹45 lakh | 3% |
| Above ₹45 lakh | 5% |
For any home above ₹45 lakh — which covers virtually all of Bengaluru''s apartment market — the rate is 5%. But that''s not the full statutory duty: Karnataka adds a 10% cess and a 2% surcharge (for urban/BBMP areas) on the stamp duty amount itself. So the effective stamp duty works out to about 5.6% of the property value. On a ₹1.2 crore flat, that''s ₹6 lakh base stamp duty plus ₹60,000 cess and ₹12,000 surcharge — ₹6.72 lakh in total.
Registration charges saw the most significant recent change. Effective 31 August 2025, Karnataka doubled the registration fee from 1% to 2% of the property value — the first revision since 2003, applicable across residential, commercial, and plotted transactions. This single change added a full percentage point to the cost of every property purchase in the state. On a ₹1.2 crore flat, registration is now ₹2.4 lakh (versus ₹1.2 lakh before the hike).
Together, stamp duty and registration on a ₹1.2 crore flat come to about ₹9.12 lakh — roughly 7.6% of the property value. This is the irreducible statutory floor; every Bengaluru buyer above ₹45 lakh pays it. Registration is now done through the Kaveri 2.0 online portal, which handles e-stamping, fee payment, and appointment booking.
GST: The Biggest Swing Factor
Goods and Services Tax is where the cost of two otherwise-identical flats can diverge by lakhs, depending on one thing: whether the property is under construction or ready to move in.
Ready-to-move-in and resale flats are completely GST-exempt, provided the property has received its occupancy certificate (OC) or completion certificate (CC). Once a building is certified complete, the transaction is treated as the sale of immovable property, which falls outside the GST framework entirely. So a ₹1.2 crore ready flat pays zero GST.
Under-construction flats attract GST, because construction is treated as a taxable service. The rates:
- 5% for non-affordable housing (the standard rate for most Bengaluru apartments), with no input tax credit.
- 1% for affordable housing — units priced at ₹45 lakh or below AND with a carpet area of 60 square metres or less in metro cities like Bengaluru. Both conditions must be met.
The GST is applied after a one-third deduction for land value (land being GST-exempt), but this is baked into the headline rate — in practice, 5% is applied to the agreement value. On a ₹1.2 crore under-construction flat, that''s ₹6 lakh in GST that the buyer of an equivalent ready flat simply doesn''t pay.
One trap to watch: amenity charges (clubhouse, parking, preferential location) bundled into the sale agreement attract GST at the same 5% rate as the flat, but if a builder bills them separately as a distinct service, they can attract 18% GST. Review the builder''s cost sheet carefully to see how these are structured.
This GST difference is a major reason ready-to-move and resale flats often represent better total value than under-construction ones, even at a similar headline price — the 5% GST saving (₹6 lakh on a ₹1.2 crore flat) plus the elimination of construction-delay risk frequently outweighs the typical discount on an under-construction unit.
Bengaluru Setup Costs: Khata and Utilities
Beyond the pan-Karnataka statutory charges, Bengaluru has its own set of municipal and utility setup costs that buyers must budget for.
Khata transfer. The khata is the BBMP record that identifies you as the property owner for property tax purposes. After registration, you must transfer the khata from the seller (or builder) to your name. The fee is roughly 2% of the stamp duty paid, or a flat ₹1,500-5,000 depending on the ward. Critically, you need a valid A-Khata — not a B-Khata — to obtain utility connections, get a home loan smoothly, and resell the property without difficulty. B-Khata properties (common in parts of North Bengaluru, Devanahalli, and Attibele) require a separate, often lengthy, conversion process. Always confirm the khata status before buying.
BESCOM electricity connection. A new electricity connection requires a security deposit based on the sanctioned load, typically ₹15,000-40,000 for a residential flat. For apartments, this is sometimes handled at the building level, but individual meter deposits often fall to the buyer.
BWSSB / Cauvery water connection. The Bangalore Water Supply and Sewerage Board levies pro-rata charges and a connection deposit for water and sewerage, typically ₹25,000-75,000 depending on the property and connection type. In newer peripheral areas not yet on the Cauvery network, water arrangements (borewells, tankers) carry their own cost considerations.
These setup costs total roughly ₹75,000-1.5 lakh for a typical Bengaluru flat — modest relative to stamp duty, but real money that''s easy to overlook in initial budgeting.
The Under-Discussed Builder Charges
This is where buyers are most often blindsided, because these charges appear in the builder''s cost sheet as separate line items rather than being included in the advertised per-square-foot price.
Covered car parking. In Bengaluru, parking is almost always charged separately from the flat — typically ₹2-8 lakh per slot depending on the project and whether it''s covered or stack parking. A crucial legal point: ensure the specific parking slot number is explicitly written into your sale agreement. Without that, the space isn''t legally yours, regardless of what you paid.
Advance maintenance. Builders typically collect 12-24 months of maintenance charges in advance at possession, at roughly ₹4-6 per square foot per month. For a 1,200 sq ft flat, that''s ₹6,000-7,000 per month, or ₹1.4-1.7 lakh for 24 months upfront.
Maintenance corpus / sinking fund. A one-time contribution to the building''s long-term maintenance reserve, typically ₹50-100 per square foot — around ₹60,000-1.2 lakh for a mid-sized flat.
Clubhouse and amenities. Many projects charge a one-time clubhouse or amenities fee, ranging from ₹1-3 lakh depending on the project''s facilities.
Preferential location charges (PLC). Premium floors, corner units, or units with better views often carry a PLC — an extra charge on top of the base price, sometimes 2-5% of the flat value.
Brokerage. On resale transactions, brokerage is typically 1-2% of the property value, paid by the buyer (sometimes split with the seller). On new builder sales, brokerage is usually paid by the builder to the channel partner, so the buyer often doesn''t pay it directly — but always confirm. On a ₹1.2 crore resale flat, 1% brokerage is ₹1.2 lakh.
Together, these builder and transaction charges can add ₹5-10 lakh on a ₹1.2 crore flat — a substantial sum that rarely features in the initial sales pitch.
Home Loan Costs and the Deposit Gap
If you''re financing the purchase, two further cost considerations apply.
Loan processing and associated charges. Lenders charge a processing fee of 0.25-0.50% of the loan amount (plus GST), along with legal verification and property valuation charges. Together these typically come to ₹25,000-50,000.
The deposit gap — the big one. This is the most important financing reality: home loans are calculated on the property value only, and lenders fund a maximum of about 80% of that value (90% for smaller-ticket affordable loans). The stamp duty, registration, GST, and all the builder and setup charges are not covered by the loan. So on a ₹1.2 crore flat:
- The lender funds up to ~₹96 lakh (80% of value).
- You pay the remaining ~₹24 lakh of the property value as down payment.
- PLUS the entire 13-20% of extra costs (₹15.6-24 lakh) from your own pocket.
This means the actual cash you need upfront is far more than the "20% down payment" figure that buyers often plan around. For a ₹1.2 crore flat, realistic upfront cash is in the range of ₹40-48 lakh (down payment plus all extra costs), not the ₹24 lakh that 20% alone suggests. Underestimating this is one of the most common and stressful planning errors Bengaluru buyers make.
The Complete Breakdown: ₹1.2 Crore Flat
Here is the full cost stack for a ₹1.2 crore Bengaluru flat, showing both the ready-to-move and under-construction scenarios:
| Cost component | Ready-to-move / resale | Under-construction |
|---|---|---|
| Stamp duty (5% + 10% cess + 2% surcharge) | ₹6,72,000 | ₹6,72,000 |
| Registration (2%) | ₹2,40,000 | ₹2,40,000 |
| GST (5% under-construction; nil if ready) | ₹0 | ₹6,00,000 |
| Khata transfer | ₹12,000 | ₹12,000 |
| BESCOM electricity deposit | ₹25,000 | ₹25,000 |
| BWSSB / Cauvery water connection | ₹40,000 | ₹40,000 |
| Covered car parking | ₹4,00,000 | ₹4,00,000 |
| Advance maintenance (24 months) | ₹1,44,000 | ₹1,44,000 |
| Maintenance corpus / sinking fund | ₹1,00,000 | ₹1,00,000 |
| Clubhouse / amenities | ₹1,50,000 | ₹1,50,000 |
| Brokerage (1%, resale only) | ₹1,20,000 | ₹0 (builder-paid) |
| Loan processing + legal/valuation | ₹50,000 | ₹50,000 |
| Total extra cost | ₹19,53,000 (16.3%) | ₹24,33,000 (20.3%) |
| Total outlay (price + extras) | ₹1,39,53,000 | ₹1,44,33,000 |
The exact figure varies with your choices — skip the clubhouse charge, take stack parking instead of covered, or buy resale without a broker, and the ready-property total can come down toward 13-14%. But the realistic planning range is 13-16% for ready/resale and 18-20% for under-construction. The single largest variable is GST, which is why the property type matters so much to the total.
Guidance Value: How It Can Raise Your Costs
One Bengaluru-specific factor worth understanding is the guidance value — the minimum property value the Karnataka government notifies for each area for registration purposes. Stamp duty and registration are charged on the higher of your actual sale price or the guidance value, never the lower.
This matters in two ways. First, if you negotiate a genuinely good deal below the area''s guidance value, you still pay statutory charges on the guidance value — you don''t get the benefit of the lower price for tax purposes. Second, Karnataka revised guidance values upward by 25-30% on average in October 2023, and further increases of 10-15% have been proposed for April 2026. Any rise in guidance value flows directly into higher stamp duty and registration, since both are calculated on it. If you''re planning to register a property in 2026, check the current guidance value for your area on the Kaveri portal, and be aware that registering before a proposed hike takes effect can save on statutory charges.
Tax Deductions Available
Some of these costs are partly recoverable through tax deductions, though only under the old tax regime.
Stamp duty and registration: deductible under Section 80C (renumbered Clause 123 in the Income Tax Act 2025) up to the overall ₹1.5 lakh 80C limit, in the financial year of purchase. This applies only to the first residential property, only to individuals, and only under the old regime. For a buyer with ₹9.12 lakh of statutory costs, only ₹1.5 lakh is deductible (and only if not already used by other 80C items), saving up to ₹46,800 at the 30% slab.
Home loan interest: deductible under Section 24(b) up to ₹2 lakh per year for a self-occupied property (old regime). Home loan principal repayment: deductible under Section 80C / Clause 123 within the ₹1.5 lakh limit. These are ongoing deductions over the loan tenure, not one-time.
Note that from FY 2026-27 the new tax regime is the default, and none of these deductions are available under it — so claiming them requires actively opting for the old regime, which only makes sense if your total deductions exceed the new regime''s benefit. Run both regimes before deciding.
How to Budget and Where to Negotiate
Practical guidance for managing the real cost:
Budget for the total, not the sticker. Plan for 13-16% over the headline price for ready properties, 18-20% for under-construction. For a ₹1.2 crore flat, set aside ₹40-48 lakh in upfront cash (down payment plus all extras), not just the 20% down payment.
Prefer ready-to-move or resale to save GST. The 5% GST saving on a ready property (₹6 lakh on ₹1.2 crore) plus the elimination of construction-delay and developer-default risk often makes ready properties better total value, even at a slightly higher headline price.
What''s negotiable: the base price itself (always negotiate, especially in resale and ready-inventory deals), brokerage (can sometimes be reduced or split), clubhouse and PLC charges (occasionally waived in slow markets), and floor-rise/PLC premiums. What''s not negotiable: stamp duty, registration, GST, and government deposits — these are fixed by statute.
Verify the khata and OC before committing. Insist on A-Khata and a valid occupancy certificate. These affect both your costs (B-Khata conversion is expensive and slow) and your ability to get a loan and resell.
Get every charge in writing. Demand a complete cost sheet listing every line item — parking, PLC, clubhouse, corpus, maintenance advance — before signing. Verbal assurances about "all-inclusive" pricing frequently don''t hold up at possession.
Common Mistakes
Budgeting only for the down payment. The biggest error. Buyers plan for 20% down and are blindsided by the additional 13-20% of costs that the loan doesn''t cover. Plan for the full upfront cash requirement.
Forgetting the August 2025 registration hike. Registration doubled from 1% to 2% on 31 August 2025. Older cost guides and calculators may still show 1% — budget for the current 2%.
Not factoring in GST on under-construction. A 5% GST on a ₹1.2 crore under-construction flat is ₹6 lakh that a ready flat doesn''t cost. Factor this into any under-construction-versus-ready comparison.
Assuming parking is included. In Bengaluru, parking is almost always charged separately (₹2-8 lakh) and must be named in the sale agreement to be legally yours. Never assume it''s bundled.
Ignoring khata status. Buying a B-Khata property without understanding the conversion cost and difficulty can create expensive problems with loans, utilities, and resale. Insist on A-Khata.
Registering on the guidance value when your price is lower — and not knowing it. Statutory charges are on the higher of sale price or guidance value. Check the guidance value before negotiating so you know your minimum statutory cost.
Not checking the occupancy certificate. Without a valid OC, a "ready" flat isn''t legally complete, may attract GST, and can have serious title and utility complications. Always verify the OC.
Frequently Asked Questions
What is the total cost of buying a home in Bengaluru beyond the price?
On top of the headline price, expect to pay about 13-16% extra for a ready-to-move or resale flat, and 18-20% for an under-construction flat (which attracts 5% GST that ready properties don''t). On a ₹1.2 crore flat, that''s roughly ₹19.5 lakh extra for ready (total ₹1.4 crore) or ₹24.3 lakh for under-construction (total ₹1.44 crore). The components are: statutory charges of about 7.6% (stamp duty 5% plus 10% cess and 2% surcharge, taking it to 5.6% effective, plus registration 2%); GST of 5% for under-construction only; Bengaluru setup costs (khata transfer, BESCOM and BWSSB/Cauvery deposits); and builder charges (car parking ₹2-8 lakh, advance maintenance, corpus, clubhouse, and resale brokerage of 1-2%). Critically, home loans fund only the property value, not these extras, so the entire amount comes from your own savings — budget ₹40-48 lakh in upfront cash for a ₹1.2 crore flat.
What are the stamp duty and registration charges in Bengaluru in 2026?
For properties above ₹45 lakh (most Bengaluru apartments), stamp duty is 5% of the value, plus a 10% cess and 2% surcharge on the duty amount, taking the effective rate to about 5.6%. Registration is 2% — having doubled from 1% on 31 August 2025, the first revision since 2003. Together, statutory charges total about 7.6% of the property value. For lower-value properties, stamp duty is 3% (₹20-45 lakh) or 2% (below ₹20 lakh). On a ₹1.2 crore flat, this means ₹6.72 lakh stamp duty (including cess and surcharge) plus ₹2.4 lakh registration, totalling ₹9.12 lakh. Both are calculated on the higher of your actual sale price or the government''s guidance value for the area, and are paid through the Kaveri 2.0 online portal at registration. Karnataka offers no gender-based concession on these charges.
Do I have to pay GST on a flat in Bengaluru?
Only on under-construction flats. Ready-to-move-in and resale flats with a valid occupancy certificate (OC) or completion certificate are completely GST-exempt, because they''re treated as the sale of immovable property rather than a construction service. Under-construction flats attract 5% GST for non-affordable housing (no input tax credit), or 1% for affordable housing (units priced at ₹45 lakh or below AND with a carpet area of 60 square metres or less in a metro like Bengaluru — both conditions required). On a ₹1.2 crore under-construction flat, 5% GST is ₹6 lakh — a cost the buyer of an equivalent ready flat doesn''t pay at all. This is a major reason ready and resale flats often offer better total value than under-construction ones. Watch for amenity charges (clubhouse, parking) billed separately as a service, which can attract 18% GST rather than the 5% flat rate.
How much cash do I need upfront to buy a ₹1.2 crore flat in Bengaluru?
Substantially more than the 20% down payment most buyers plan for. Home loans fund a maximum of about 80% of the property value (₹96 lakh on a ₹1.2 crore flat), and crucially, they fund only the property value — not stamp duty, registration, GST, or any builder and setup charges. So your upfront cash requirement is the ~20% down payment (₹24 lakh) PLUS the entire 13-20% of extra costs (₹15.6-24 lakh), totalling roughly ₹40-48 lakh for a ready property. For an under-construction flat with 5% GST, it''s toward the higher end. Underestimating this — planning for just the ₹24 lakh down payment — is one of the most common and stressful errors Bengaluru buyers make. Always budget for the down payment plus all extra costs as your true upfront cash requirement.
What is khata and why does it matter when buying in Bengaluru?
The khata is the BBMP (municipal) record identifying you as the property owner for property tax purposes. After registering a property, you must transfer the khata to your name, at a fee of roughly 2% of the stamp duty paid or a flat ₹1,500-5,000 depending on the ward. The critical distinction is between A-Khata and B-Khata. An A-Khata signifies a fully legal, compliant property and is required to obtain utility connections, secure a home loan smoothly, and resell without difficulty. A B-Khata indicates a property with some regulatory non-compliance (common in parts of North Bengaluru, Devanahalli, and Attibele) and requires a separate, often lengthy and expensive, conversion process to A-Khata before you can do those things. Always confirm the khata status before buying — purchasing a B-Khata property without understanding the conversion cost and difficulty can create serious problems with financing, utilities, and future resale.
Is it cheaper to buy a ready-to-move or under-construction flat in Bengaluru?
Ready-to-move (or resale) is often better total value, primarily because of GST. An under-construction flat attracts 5% GST (₹6 lakh on a ₹1.2 crore property), while a ready flat with an occupancy certificate is GST-exempt. On top of that, ready properties eliminate construction-delay risk and developer-default risk, and you can see exactly what you''re buying. Under-construction flats sometimes have a lower headline price or attractive payment plans, but the 5% GST plus the risk premium frequently outweighs that discount. The total extra cost is about 13-16% over the headline for ready/resale versus 18-20% for under-construction, with the GST being the main difference. That said, under-construction can make sense if the price discount is genuinely large, the builder is highly reputable with a strong delivery track record, and you don''t need to move in immediately. Run the full cost comparison including GST before deciding — the ready flat''s GST exemption is a real ₹6 lakh advantage on a ₹1.2 crore purchase.
Can I claim tax deductions on stamp duty and registration in Bengaluru?
Yes, but only under the old tax regime and within limits. Stamp duty and registration charges are deductible under Section 80C (renumbered Clause 123 in the Income Tax Act 2025) up to the overall ₹1.5 lakh 80C limit, in the financial year of purchase. This applies only to your first residential property, only to individuals (not businesses), and only if you opt for the old tax regime. For a buyer with ₹9.12 lakh of statutory costs, only ₹1.5 lakh is deductible — and only to the extent your 80C limit isn''t already used by other instruments like EPF, PPF, or ELSS — saving up to ₹46,800 at the 30% slab. Separately, home loan interest is deductible under Section 24(b) up to ₹2 lakh per year, and home loan principal under 80C, both as ongoing deductions over the loan tenure. Note that from FY 2026-27 the new tax regime is the default and offers none of these deductions, so claiming them requires actively choosing the old regime — worthwhile only if your total deductions exceed the new regime''s lower-rate benefit.
