Tamil Nadu’s Registration Department has ordered a State-wide review of property market-value guidelines used for assessing stamp duty on property transactions. The move follows the identification of several inconsistencies in the way streets, agricultural land and properties in rapidly urbanising areas are currently valued.
The review could lead to higher guideline values in some locations and lower values in others. However, the government has not yet announced a timeline for implementing the revised values.
For property buyers, sellers, landowners and developers, the exercise could become significant because a change in the guideline value can affect the value adopted for property registration and, consequently, the applicable registration costs.
Why is Tamil Nadu reviewing property guideline values?
The review follows a meeting of the State Valuation Committee held on July 15, 2026.
Following the meeting, the Inspector General of Registration, G.K. Arun Sundar Thayalan, issued directions to district collectors on July 18, 2026. Valuation sub-committees have been asked to examine and rectify anomalies identified in the existing guideline-value system.
The State-level review has identified eight categories of inconsistencies relating to the valuation of streets, agricultural land and peri-urban properties.
The exercise is therefore not simply a proposal to increase guideline values across Tamil Nadu. Instead, the objective is to identify locations where the existing values do not adequately reflect comparable road characteristics, land use or the development taking place around them.
Key Issues in Guideline Value Revision
1. Electricity data to be used for street classification
Electricity-connection data from TNeGA, along with property-tax records, will be used to classify streets as commercial, mixed-use, or residential. Streets with 60% or more commercial connections will be marked commercial, 25–59% as mixed-use, and below 25% as residential. This helps identify areas where actual land use has changed but official classification has not yet been updated.
2. Similar roads may be brought under more uniform values
The valuation committee has identified cases where roads with similar physical and usage characteristics have been assigned different guideline values. This includes short connecting roads and cross-roads that do not have any clear basis for variation in pricing. The sub-committees have been instructed to rationalise such discrepancies and adopt more uniform values where justified.
3. Why this matters
Guideline values are assigned based on specific locations, but neighbouring areas with similar development often show large pricing differences. This leads to inconsistencies during property registration and valuation. The current exercise aims to correct such anomalies rather than allowing arbitrary location boundaries to drive major value gaps.
4. Uneven highway valuations
Guideline values along major corridors like the ECR and Poonamallee highways vary widely, ranging from ₹2,000 to ₹500 per sq ft. This is despite similar frontage, connectivity, and development intensity along these stretches. The disparity highlights the need for a more consistent valuation framework.
5. Outdated values in rapidly urbanising areas
In 1,020 villages and town panchayats near municipalities and corporations, guideline values may not reflect recent urban growth. These areas are being reviewed against nearby urban localities with higher property values. The aim is to ensure that rapid development is properly captured in official valuations.
6. Agricultural land within municipal and corporation limits
The review also covers agricultural land located inside urban local-body boundaries. A minimum guideline value is being considered for such land based on nearby residential plot values, rather than outdated agricultural rates. This does not change land use classification but only affects valuation methodology.
7. What about errors in land records?
The exercise also focuses on correcting errors in land records, including missing survey numbers and incorrect classifications. These corrections aim to improve the accuracy of the valuation database used for property registration. The updated system is intended to make guideline values more reliable and consistent across regions.

How will the authorities determine revised values.
The review will not depend on a single source of information.
The valuation process may consider factors such as:
- Recent registered property transactions
- Property advertisements and listings
- Field-level inspections
- Land acquisition compensation data
- Bank auction and sale records
- Electricity consumption patterns of residential, commercial, and industrial establishments
These inputs will be examined by district-level authorities before revised values are finalised.
This is important because a single high-value property transaction should not determine the guideline value of all properties in an entire locality.
Will property guideline values increase all over TN?
Not necessarily.
This is a review of existing guideline values, not a uniform State-wide increase. Values may rise in some areas and even reduce in others based on location, road type, land use, development, comparable sales, street classification, and committee findings.
As a result, property owners should not assume automatic increases.
This review could also affect registration costs—higher revised values may increase charges, while lower values may reduce them. However, no final revised rates or implementation timeline have been announced yet.
What should property buyers and owners do now?
Property owners and prospective buyers should avoid assuming that a guideline-value increase is imminent across the State.
Instead, those planning a property transaction should:
- Check the property’s existing guideline value and classification.
- Check whether the street is currently classified as residential, mixed-use or commercial.
- Pay attention to any proposed changes affecting the particular locality.
- If purchasing property in a rapidly developing peri-urban area, check surrounding guideline values and recent transactions.
- Verify survey-number and land-use details before registration.
Those planning an immediate transaction should also distinguish between the current applicable guideline value and a possible future revision. For the latest updates on guideline value changes, check the Guideline Value Tool on the Verified.RealEstate.
What happens next?
District-level valuation sub-committees will review the identified anomalies across highways, fast-growing peri-urban areas, agricultural land within urban limits, and other inconsistent valuations.
The exercise has begun, but the revised guideline values are not yet in effect, and the government is yet to announce implementation.
Conclusion
This review is a broad correction exercise aimed at fixing uneven valuations between similar roads, outdated rates in rapidly urbanising areas, and inconsistencies in agricultural and peri-urban land pricing. It also uses electricity-connection data to better map actual land use, covering 1,020 villages and town panchayats along with key highway corridors. However, no immediate change applies—final impact will be known only after committee recommendations are approved and officially notified.
