Step‑by‑Step: How to Calculate Stamp Duty
Follow these steps to find out how much stamp duty you need to pay:
Step 1: Find Guideline Value
Open the TNREGINET portal in your browser (mobile or computer).
Go to Guideline Value Search.
Enter the property details:
District
Sub‑Registrar Office (SRO)
Street or Survey Number
Property Type (Residential, Commercial, etc.)
Click Search to see the guideline value per sq ft.
Write down the guideline value.
Step 2: Get the Property Area
You need the total area of the property in square feet.
For example:
Guideline value: ₹3,000 per sq ft
Plot area: 2,400 sq ft
Step 3: Multiply Area by Guideline Value
Multiply the area by the guideline value:
2,400 sq ft × ₹3,000 = ₹7,200,000
This gives you the guideline value in rupees.
Step 4: Compare With Sale Price
If the agreed sale price is higher than the guideline value, the government will use the higher number to calculate stamp duty.
Example:
Government base value: ₹8,000,000 (higher)
Sale price: ₹8,000,000
Guideline value: ₹7,200,000
Step 5: Apply Stamp Duty Percentage
In Tamil Nadu, stamp duty is usually 7% of the base value (may vary with government changes).
Using our example:
= ₹560,000
Base value: ₹8,000,000
Stamp duty: 7% of ₹8,000,000
Step 6: Add Registration Charges
Registration charges in Tamil Nadu are usually 1% of the base value (check the latest rates).
So:
= ₹80,000
Registration charges = 1% of ₹8,000,000
Final Amount to Pay
Total payable = Stamp duty + Registration charges
= ₹560,000 + ₹80,000
= ₹640,000
