Stamp duty in India is a state government tax you must pay when registering a property transaction — it typically ranges from 3% to 8% of the property's market value depending on the state, property type, buyer's gender, and location. The Indian Stamp Act, 1899 (Section 3) makes it mandatory to pay stamp duty on every instrument (document) that transfers property rights, and under-payment or non-payment can result in the document being impounded and penalties of up to 200% of the deficit. You calculate stamp duty on the higher of the actual transaction price or the government guideline value — whichever is greater.
Why this matters
Stamp duty is the second-largest cost in any property purchase after the price itself. On a Rs 1 crore property in Maharashtra, stamp duty and registration charges can add Rs 7-8 lakh to your total cost. Getting this calculation wrong means either overpaying (money you cannot recover) or underpaying (which results in penalties, legal complications, and potential registration refusal). Many first-time buyers are shocked by the stamp duty amount because it is not prominently discussed during negotiations. Understanding how stamp duty works also reveals legitimate ways to save — such as registering in a woman's name to claim the female buyer concession available in many states.
Step-by-step: How to calculate stamp duty
1. Determine the property's value for stamp duty purposes
Stamp duty is calculated on the higher of two values:
- The actual transaction value (the price you are paying)
- The government guideline value (also called circle rate, ready reckoner rate, or guidance value depending on the state)
Every state government publishes official guideline values for different areas. These are updated annually or bi-annually and represent the minimum value at which the government expects property transactions to occur.
In practice: Check your state's guideline value online. In Maharashtra, search for the "Annual Statement of Rates" (ASR) or "Ready Reckoner Rate" on igrmaharashtra.gov.in. In Karnataka, check "guidance value" on kaveri.karnataka.gov.in. In UP, check "circle rate" on igrsup.gov.in.
2. Identify the applicable stamp duty rate
Stamp duty rates vary by state, property type, buyer gender, and sometimes by location within the state (urban vs rural). Here are the rates for major states as of 2026:
| State | Male Buyer | Female Buyer | Joint (M+F) | Registration Fee |
|---|---|---|---|---|
| Maharashtra (municipal corp.) | 6% | 5% | 5% | 1% (max Rs 30,000) |
| Maharashtra (Thane, Pune, Mumbai) | 7% | 6% | 6% | 1% (max Rs 30,000) |
| Karnataka (Bangalore urban) | 5% | 3% | 4% | 1% (no cap) |
| Karnataka (rural) | 3% | 2% | 2.5% | 1% |
| Tamil Nadu | 7% | 7% | 7% | 4% |
| Delhi | 6% | 4% | 5% | 1% |
| Uttar Pradesh | 7% | 6% | 6.5% | 1% |
| Rajasthan | 6% | 5% | 5.5% | 1% |
| West Bengal (Kolkata urban) | 7% | 6% | 6.5% | 1% |
| Telangana | 6% | 6% | 6% | 0.5% |
| Haryana | 7% (male) | 5% (female) | 6% | Included in stamp duty |
| Gujarat | 4.9% | 4.9% | 4.9% | 1% |
| Kerala | 8% | 8% | 8% | 2% |
Important: These rates apply to sale deeds for residential property. Commercial property, gift deeds, lease deeds, and other instruments may have different rates. Some states also levy additional cesses — for example, Maharashtra charges a 1% local body tax and a 1% metro cess in Mumbai.
3. Calculate the stamp duty amount
Formula: Stamp Duty = Property Value (higher of transaction price or guideline value) x Applicable Stamp Duty Rate
Example: You are a male buyer purchasing a flat in Bangalore for Rs 80 lakh. The government guidance value is Rs 75 lakh.
- Value for stamp duty = Rs 80 lakh (higher of the two)
- Stamp duty rate = 5% (male buyer in Bangalore urban)
- Stamp duty = Rs 80,00,000 x 5% = Rs 4,00,000
- Registration fee = Rs 80,00,000 x 1% = Rs 80,000
- Total = Rs 4,80,000
If the same property were registered in a woman's name: Stamp duty = Rs 80,00,000 x 3% = Rs 2,40,000. Savings = Rs 1,60,000.
4. Pay the stamp duty
You can pay stamp duty through one of these methods:
- E-stamping: Purchase an e-stamp certificate through SHCIL (Stock Holding Corporation of India Limited) at shcilestamp.com or at authorised bank branches. This is the most common and convenient method.
- Franking: Get the deed franked at an authorised bank. The bank prints a franking impression on the deed indicating the stamp duty has been paid.
- Physical stamp paper: Purchase non-judicial stamp paper of the required denomination from an authorised vendor. This method is becoming less common as states move to e-stamping.
In practice: E-stamping is recommended because it is difficult to forge, can be verified online, and is accepted across all Sub-Registrar offices. Keep the original e-stamp certificate safe — you will need it during registration.
What if things go wrong
If you underpay stamp duty
Under Section 33 of the Indian Stamp Act, the registering authority can impound the document if it is not properly stamped. You will need to pay the deficit stamp duty plus a penalty. Most states charge a penalty of 2% per month of the deficit amount, subject to a maximum of 200% of the deficit (Section 35-40 of the Indian Stamp Act). Some states have different penalty structures.
If you disagree with the guideline value
If you believe the government guideline value for your property is too high, you can apply for "adjudication" under Section 31 of the Indian Stamp Act. The Collector will determine the correct market value and the stamp duty payable. This process takes 1-3 months.
If you paid stamp duty but registration fails
If the registration is cancelled or the transaction falls through, you can apply for a refund of stamp duty in most states. The process varies — in Maharashtra, you must apply to the Collector within 2 years. Typically, a small deduction (1-5%) is retained as processing charges.

Common myths
Myth: Stamp duty is the same across India. Reality: Stamp duty is a state subject. Each state sets its own rates, and rates can vary even within a state (urban areas often have higher rates than rural areas). Always check the specific rate for your state and location.
Myth: You can save stamp duty by showing a lower transaction price. Reality: Stamp duty is calculated on the higher of the actual price or the government guideline value. Showing a lower price does not reduce stamp duty if the guideline value is higher. Moreover, declaring a lower value is a criminal offence under the Benami Transactions (Prohibition) Act and the Income Tax Act, and can result in penalties, prosecution, and the transaction being declared void.
Myth: Stamp duty is a one-time cost — you never pay it again. Reality: Stamp duty is payable on every property transaction. If you sell the property later, the new buyer pays stamp duty again. You also pay stamp duty on gift deeds, lease deeds, and mortgage deeds — though the rates are usually lower than for sale deeds.
Myth: Registering property in a woman's name is just a stamp duty trick. Reality: When you register property in a woman's name, she becomes the legal owner. This is a genuine transfer of ownership, not just a tax-saving strategy. Ensure both parties understand and agree to the ownership implications.

Frequently asked questions
Can I get a stamp duty concession if I am a first-time buyer? Some states offer concessions for first-time buyers, but this is not universal. The most widely available concession is the reduced rate for women buyers, offered in states like Maharashtra, Karnataka, Delhi, Haryana, and Rajasthan. Check your state's current notification for other concessions.
Is stamp duty different for flats versus independent houses? The stamp duty rate is typically the same for all residential properties in a state. However, the calculation base differs — for flats, stamp duty is calculated on the agreement value or the guideline value per square foot multiplied by the carpet area. For independent houses, it is calculated on the land value plus construction value.
When must stamp duty be paid? Stamp duty must be paid before or at the time of executing the sale deed. You cannot register the deed without paying the full stamp duty. The e-stamp certificate or franked stamp paper should be ready before you visit the Sub-Registrar's office.
Can NRIs pay stamp duty in foreign currency? No. Stamp duty must be paid in Indian rupees. NRIs can pay from their NRE/NRO bank account in India through the normal e-stamping or franking process.
