How TNREGINET Handles Guideline Value Discrepancies (2026)
When buying or selling property in Tamil Nadu, the guideline value is the government-set minimum value used to calculate stamp duty and registration fees. Sometimes, property buyers, sellers, or banks notice that the market value of a property is higher or lower than the TNREGINET guideline value. This can create confusion or discrepancies during registration.
TNREGINET has processes to handle such situations and ensure proper registration while following government rules.

What Causes Guideline Value Discrepancies
Discrepancies usually occur due to:
Market fluctuations:
The property’s actual selling price may be higher than the guideline value in the portal.
Different property zones:
Guideline values are set per zone or area and may not reflect unique characteristics of the property.
Old data updates:
Guideline values are updated periodically, so older values may not match current market rates.
Input errors:
Mistakes in entering survey numbers, sub-division, or area size can show incorrect guideline values.
Understanding why discrepancies happen helps buyers and sellers plan their registration correctly.

Automatic Alerts:
The portal may flag properties where the entered market value is below the guideline value, prompting the user to check details.

Document Review:

The final stamp duty is usually calculated based on the higher of the market value or guideline value, ensuring compliance with legal requirements.
Correction Requests:
If the portal shows an incorrect guideline value due to input errors or zone misclassification, users can request correction through TNREGINET’s helpdesk or the local sub-registrar office.
