To buy a property is one of the most remarkable financial decisions in a person’s life. Whether it’s a plot, apartment or independent house, it’s not just the cost of the property you need to consider; stamp duty and registration charges form a crucial part of your total investment. These charges are mandatory under law to validate ownership and record the transaction officially with the government.
In Tamil Nadu, the Inspector General of Registration (IGR) governs the collection of stamp duty and registration charges. In 2025, the state continues to follow its well-established structure, but with a few key updates, including revised slabs for apartments, a women’s concession and an emphasis on guideline value-based assessments. This blog provides a complete breakdown of the latest rates, calculations and procedural details for property buyers and investors in Tamil Nadu.
What Are Stamp Duty and Registration Charges?
Stamp Duty is a state-imposed tax that makes a legal document, such as a sale deed, gift deed or lease agreement, valid in the eyes of law. It serves as proof of ownership and protects your rights over the property in court.
Registration Charges, on the other hand, are fees paid to record the property transaction in government records under the Registration Act, 1908. Only after registration does the ownership transfer legally from the seller to the buyer.
Together, these two charges ensure that the transaction is transparent, accurate, legally binding and recognized by the Tamil Nadu government.
Current Rates of Stamp Duty and Registration Charges in Tamil Nadu (2025)
As of 2025, the rates applicable in Tamil Nadu may vary, which will be based on the type of property and nature of the transaction.
(A) For Sale/Conveyance of Immovable Property
- Stamp Duty: 7% of the market value or guideline value (whichever is higher)
- Registration Charges: 4% of the market value or guideline value
Total Effective Cost: 11% of the property’s value
(B) For Apartment/Flat Purchases (Composite Value Method)
From 2025 onwards, the Tamil Nadu government applies a slab-based approach to determine the required stamp duty on apartments, considering both the undivided land share (UDS) and constructed area together as a composite value.
- Stamp Duty:
- 4% for properties valued up to ₹50 lakh
- 5% for properties between ₹50 lakh and ₹3 crore
- 7% for properties above ₹3 crore
- Registration Charges: 2% of the composite value
This slab system ensures fair taxation and reduces the burden on middle-income buyers purchasing affordable flats.
(C) For Gift, Exchange, or Family Transfer
- Gift Deed (in favour of family members): 1% stamp duty on market value and 1% registration fee (subject to conditions)
- Partition Deed: 1% stamp duty and 1% registration fee on the market value of the separated share
- Power of Attorney: 1% stamp duty and registration fee, depending on scope (maximum cap applicable)
How Is Stamp Duty Calculated?
Stamp duty in Tamil Nadu is always charged on the higher value between:
- The consideration value (actual sale price mentioned in the document), and
- The guideline (circle) value is fixed by the government for that location.
The Guideline Value reflects the minimum value at which property transactions can be registered in a particular area. You can check the latest guideline value on the official government portal TNREGINET.
For apartments, the composite value (super built-up area + undivided land share) is used to calculate the duty.
Example Calculations
Let’s understand with practical examples: –
Example 1: Sale of a Plot
- Property Value: ₹50,00,000
- Stamp Duty (7%): ₹3,50,000
- Registration Charges (4%): ₹2,00,000
Total Payable: ₹5,50,000
Effective Cost: 11%
Example 2: Sale of an Apartment
- Composite Value: ₹50,00,000
- Stamp Duty (4%): ₹2,00,000
- Registration Charges (2%): ₹1,00,000
Total Payable: ₹3,00,000
Effective Cost: 6%
Example 3: Women’s Concession (New in 2025)
The Tamil Nadu government introduced a 1% concession in registration fees for women buyers purchasing property worth up to ₹10 lakh.
- Property Value: ₹9,00,000
- Stamp Duty (7%): ₹63,000
- Registration Charges (3% after concession): ₹27,000
Total Payable: ₹90,000.
This initiative aims to promote female homeownership and financial independence.
