What Is Stamp Duty and Who Pays It: Buyer, Seller, or Both?

Overview: Who Pays Stamp Duty, Buyer or Seller?

Buying a property involves more than paying the price negotiated with the builder or seller. Stamp duty and registration charges form a significant part of the final acquisition cost, particularly in Bangalore where most residential properties fall into the higher value bracket. In Karnataka, stamp duty on a sale transaction can range from 2% to 5% depending on the applicable property category and value, while the registration fee is currently 2%.

A common question is: who pays stamp duty, the buyer or seller? In a standard property sale, the buyer generally pays stamp duty and registration costs because the property is transferred and registered in the buyer’s name. But understanding who pays is only the beginning. The amount also depends on the value on which duty is assessed, the nature of the transaction and the applicable Karnataka rules.

This article explains what stamp duty is, how it differs from registration charges, how Guidance Value in Karnataka affects the calculation, what Bangalore buyers should budget for, and what can happen if the required stamp duty is not paid correctly.

Key Takeaways

• In a conventional property purchase, the buyer generally pays stamp duty and registration charges.
• Karnataka currently applies different stamp duty rates depending on the property value and transaction category.
• Karnataka increased its property registration fee from 1% to 2% with effect from August 31, 2025.
• Stamp duty is generally assessed using the applicable value under Karnataka’s valuation rules, so the guidance value can directly affect the amount payable.
• Paying inadequate stamp duty can create legal and registration complications, so buyers should calculate statutory costs before finalising their property budget.

What Is Stamp Duty on Property?

Stamp duty is a tax imposed by the state government on certain legal instruments and transactions. When ownership of an immovable property is transferred through a sale deed, the applicable document must be properly stamped according to the state’s stamp law.

In Karnataka, these requirements are governed primarily by the Karnataka Stamp Act, 1957, along with subsequent amendments and applicable rules.

For a homebuyer, stamp duty is therefore not an optional administrative fee. It forms part of the legal process through which the property transaction is documented.

The amount can depend on factors such as:

• Property value
• Type of instrument or transaction
• Applicable guidance or market value
• Location and applicable statutory additions
• Concessional provisions, if any, that apply to the transaction

This is why a buyer should not estimate the final cost simply by applying a percentage found on an old property blog.

Current rules matter.

Who Pays Stamp Duty: Buyer or Seller?

For a conventional sale of property, the buyer generally pays the applicable stamp duty on the conveyance through which ownership is transferred.

The practical reason is straightforward. The buyer is acquiring the property and needs the transfer instrument properly stamped and registered to establish the transaction in their favour.

The seller still has important financial and legal responsibilities. Depending on the transaction, these can include settling existing liabilities, providing title documents and dealing with applicable tax obligations. But the stamp duty associated with registering a normal purchase is generally part of the buyer’s acquisition cost.

This distinction should be discussed before signing the final agreement so that neither side makes assumptions about who will bear a particular transaction expense.

Can the Buyer and Seller Agree to Share Stamp Duty?

Commercial terms between buyers and sellers can sometimes be negotiated, particularly in resale transactions. A seller could theoretically adjust the property price or agree to bear certain transaction expenses as part of the overall negotiation.

That does not change how the statutory liability attached to the relevant instrument is treated under the applicable law.

From a budgeting perspective, a buyer should therefore assume that applicable stamp duty and registration charges will form part of their purchase cost unless the transaction has been specifically structured and professionally reviewed otherwise.

Stamp Duty and Registration Charges in Karnataka in 2026

One reason buyers become confused about the total registration cost is that stamp duty and registration charges are not the same thing.

Stamp duty is the tax payable on the relevant property instrument. The registration fee is the separate charge associated with registering the document.

Karnataka’s registration fee was increased from 1% to 2% effective August 31, 2025. Buyers relying on older calculators or articles may therefore underestimate their current registration budget.

For property purchases commonly discussed in the Bangalore market, the headline stamp duty structure is often represented as:

• Up to ₹20 lakh: 2% stamp duty for qualifying transactions
• ₹20 lakh to ₹45 lakh: 3% stamp duty for qualifying transactions
• Above ₹45 lakh: 5% stamp duty

Additional cess and surcharge provisions may also apply, which means the final statutory outgo can be higher than simply adding the headline stamp duty percentage and registration fee.

For a typical Bangalore flat above ₹45 lakh, the overall statutory registration-related cost can therefore move materially beyond 7% once the applicable duty, registration fee and statutory additions are considered.

Buyers should verify the exact calculation for their property rather than treating these percentages as a universal quotation.

Stamp Duty vs Registration Charges: What Is the Difference?

The two terms are frequently used together, which makes them sound like one charge. They serve different purposes.

• Stamp duty is the tax imposed on the legal instrument recording the property transaction.
• Registration charges are the fees associated with formally registering that document with the appropriate registration authority.

Both can be payable during the same property purchase, but paying one does not eliminate the other.

This distinction matters when estimating your total acquisition cost. A buyer who budgets only for the headline property price and stamp duty can still be caught off guard by registration fees and other applicable charges.

For example, if you are considering a ₹1 crore apartment, your actual cash requirement is not simply the down payment plus the home loan. You also need to account for stamp duty, registration charges and other applicable acquisition costs that may not be financed in the same way as the property price.

How Does Guidance Value in Karnataka Affect Stamp Duty?

Guidance Value in Karnataka is an important concept for anyone calculating the cost of property registration.

Broadly, it represents the government notified benchmark value used for property registration purposes in a particular area. Guidance values differ across locations and property categories, so two similarly sized properties in different parts of Bangalore can have very different benchmark values.

Stamp duty is not necessarily calculated only on whatever price the buyer and seller decide to write into the transaction.

Where the applicable guidance or market value is higher than the declared consideration, the higher applicable value can affect the duty calculation.

How to Calculate Stamp Duty on a Flat in Bangalore

A stamp duty calculator for Bangalore can give you an initial estimate, but the result is only useful when the correct property value and current rates are used.

A practical calculation starts with three questions:

1. What is the agreed consideration for the property?
2. What value is applicable under Karnataka’s guidance and valuation framework?
3. Which current stamp duty, cess, surcharge and registration rates apply to this transaction?

Assume, purely for illustration, that a Bangalore flat is valued at ₹80 lakh for duty purposes and attracts the standard 5% headline stamp duty applicable to that category.

The base stamp duty alone would be:

₹80,00,000 × 5% = ₹4,00,000

The current 2% registration fee, if calculated on the same ₹80 lakh base for the transaction, would be:

₹80,00,000 × 2% = ₹1,60,000

That already produces ₹5.6 lakh before accounting for applicable cess, surcharge or other charges.

This is why buyers should calculate registration-related expenses before deciding how much property they can afford.

A buyer with an ₹80 lakh total cash budget should not automatically shortlist an ₹80 lakh flat.

Are There Karnataka Stamp Duty Exemptions for Homebuyers?

Buyers often search for a Karnataka stamp duty exemption expecting a broad exemption for first-time buyers, women buyers or particular home loan categories.

That assumption can be risky.

Karnataka does have different duty provisions and concessional treatment for certain transaction types and property values, but buyers should not assume that a general exemption applies to an ordinary residential purchase simply because they fall into a particular demographic category.

What Happens If Stamp Duty Is Not Paid?

Failing to pay the required stamp duty is not comparable to forgetting a small processing fee.

An instrument that is insufficiently stamped can face legal and procedural consequences. Depending on the circumstances and applicable law, authorities may require payment of the deficient duty along with penalties before the document can be properly acted upon.

Improper stamping can also create problems when the document later needs to be relied upon in legal proceedings or during another property transaction.

This becomes especially important when buyers attempt to reduce registration costs by understating the transaction value.

If the declared consideration is lower than the value applicable under Karnataka’s valuation framework, the authorities can examine the valuation rather than automatically accepting the number written into the sale document.

Saving money through artificial undervaluation can therefore create a much larger problem than the amount initially avoided.

How Stamp Duty Changes Your Real Property Budget

Stamp duty becomes particularly important because it sits outside the headline price used to market a property.

Suppose you have decided that your maximum property budget is ₹1 crore.

A project priced at exactly ₹1 crore may already be above your real affordability once you include:

• Stamp duty
• Registration charges
• Applicable cess and surcharge
• Home loan-related charges
• Legal verification
• Brokerage where applicable
• Maintenance or corpus-related payments
• Interiors and moving costs

The smarter approach is to work backwards.

First determine your total acquisition budget. Then subtract the statutory and transaction costs. What remains is closer to the property price you can realistically afford.

This sounds like a minor budgeting adjustment, but on a Bangalore property it can involve several lakh rupees.

A Common Stamp Duty Mistake Buyers Should Avoid

One of the most common mistakes is using an old stamp duty calculator for Bangalore without checking when its rates were last updated.

This is particularly relevant in 2026 because Karnataka’s registration fee changed from 1% to 2% in August 2025. An outdated calculator can therefore understate registration cost by 1% of the applicable property value.

On a ₹1 crore property, that difference alone can be ₹1 lakh.

Another mistake is assuming that stamp duty will always be calculated using the negotiated purchase price. Guidance and applicable market valuation rules can affect the taxable value.

The final mistake is treating stamp duty as something to calculate after negotiating the property.

It belongs in the affordability calculation from the beginning.

Final Thought: Calculate the Full Cost Before You Commit

So, who pays stamp duty, buyer or seller? For a conventional property purchase, the buyer generally bears the applicable stamp duty and registration expenses. But the more useful lesson is that these costs should be understood before you decide what property price you can afford.

Stamp duty, registration fees, guidance value and other transaction expenses can add several lakh rupees to a Bangalore purchase. A property that fits your budget on the listing page may look very different once the complete acquisition cost is calculated.

At Brickfi, we help buyers evaluate a property beyond its advertised price. Looking at pricing, project characteristics, builder history and other decision factors alongside transaction costs gives you a more realistic picture of what you are actually committing to.

The goal is simple: know the full cost before the property becomes an emotional decision.

FAQs: Who Pays Stamp Duty, Buyer or Seller?

1. Who pays stamp duty when buying property in Bangalore?

In a conventional property sale, the buyer generally pays the applicable stamp duty because the property is being transferred and registered in the buyer’s name.

2. What are the stamp duty and registration charges in Karnataka in 2026?

The applicable stamp duty depends on the transaction and property value. Commonly cited headline rates range from 2% to 5%, while Karnataka’s property registration fee is currently 2% following the increase effective August 31, 2025. Applicable cess and surcharge can increase the final amount.

3. What is Guidance Value in Karnataka?

Guidance value is the government-notified benchmark used in property valuation and registration. If the applicable guidance or market value exceeds the declared transaction price, it can affect the value on which stamp duty is calculated.

4. Is stamp duty different from property registration charges?

Yes. Stamp duty is a tax imposed on the relevant legal instrument, while the registration fee is charged for formally registering the document. Buyers need to account for both when estimating the cost of purchasing a property.

5. What happens if stamp duty is not paid correctly?

An inadequately stamped document can face registration, evidentiary and legal complications. Authorities may require payment of deficient duty and applicable penalties. Buyers should therefore verify the current amount before completing the transaction.
