Property transactions in Tamil Nadu are legally linked to something called the Guideline Value. Whether you are buying land, selling a plot, registering a house, or applying for a bank loan, guideline rates are unavoidable. For the year 2026, the Government of Tamil Nadu has made these values available digitally through TNREGINET, ensuring transparency and accuracy.
1. What Is a Guideline Value?
A Guideline Value is the minimum government-approved value of land or property fixed for a specific area, street, or survey number.
- It is area-specific
- It differs from street to street
- It is not negotiable during registration
- It is fixed by the government, not by buyers or sellers
During property registration, stamp duty and registration charges are calculated based on this value (or the sale value, whichever is higher).
2. Who Fixes Guideline Values in Tamil Nadu?
Guideline values are officially fixed and published by the
Registration Department, Government of Tamil Nadu
- The online access platform is

3. Why Guideline Rates Are Important
Guideline values exist to:
- Prevent undervaluation of property
- Ensure correct stamp duty collection
- Reduce black money transactions
- Standardize property registration values
Without guideline rates, properties could be registered at very low values to avoid tax.
