Difference Between Market Value and Guideline Value in Tamil Nadu – What Every Buyer Must Know in 2025

When buying or selling property, two terms often cause confusion among buyers and sellers: market value and guideline value. While they may sound similar, these values serve very different purposes and have distinct implications, especially when it comes to property transactions in Tamil Nadu.

In this blog, we’ll break down the key differences between market value and guideline value, explain how they are determined, and provide insights specific to Guideline Value in Tamil Nadu in 2025.

To better understand how market and guideline values differ in real scenarios, take a look at available property listings from key locations across Tamil Nadu

Understanding Market Value vs Guideline Value

What is Market Value?

Market value refers to the price a buyer is willing to pay for a property in an open and competitive market. It reflects the true value of the property based on factors like:

Location and accessibility
Proximity to schools, hospitals, and transportation
Current demand and supply
Property condition and age
Recent sales of similar properties

Example:

If a flat in Chennai is sold for ₹9,000 per sq.ft due to its premium location and modern amenities, then ₹9,000 per sq.ft is the market value, even if the government’s guideline value is lower.

What is Guideline Value?

Also known as circle rate, guidance value, or ready reckoner rate, the guideline value is the minimum rate set by the government at which a property can be registered.

It serves as the benchmark for calculating stamp duty and registration charges, which makes it crucial for taxation and legal documentation.

How is Guideline Value Determined?

Set by the Tamil Nadu Registration Department
Based on location, type of property, infrastructure development
Revised periodically (usually every few years)
Published on the Tamil Nadu Registration Department website

Example:

If a plot's guideline value in Coimbatore is ₹7,000 per sq. ft, even if it's sold for ₹9,000 per sq.ft (market value), the stamp duty will be calculated on ₹7,000, unless the declared sale value is higher.

Why the Difference Matters

Understanding the difference between market value and guideline value is essential for:

Accurate cost estimation before a purchase or sale
Avoiding legal complications during registration
Budget planning for stamp duty and registration charges
Evaluating property investments

In some cases, if the declared sale price is significantly higher than the guideline value, the difference may trigger income tax scrutiny for both buyers and sellers.
