G.O. (Ms.) No.89, Amendment to Property Market Value Guideline Rules, 2025

What the government order changes

G.O. (Ms.) No.89 of the Commercial Taxes and Registration (J1) Department, dated 23 June 2025, approves amendments to the rules governing property market value guidelines under the Indian Stamp Act, 1899. The appended notification was directed to be published in an Extraordinary issue of the Tamil Nadu Government Gazette dated 23 June 2025.

The main body refers to the Tamil Nadu Stamp rules framed in 2010, while the appended notification describes the rules being amended as the 2016 rules. The supplied document does not explain this difference.

Who may be affected

The amendments are relevant to registering officers, valuation authorities, property buyers, owners, developers and professionals dealing with guideline values. They are particularly relevant to apartments, flats, villas, vilament or villament properties, and row houses where land and structure are valued together.

New definitions

The appended notification adds the following concepts:

• Composite value means the market value of listed residential property types, including the undivided share of land, calculated using the super built-up area.
• Super built-up area means the total area of the property, including built-up area and common areas such as lifts and staircases.
• Immovable property has the meaning assigned under the Registration Act, 1908.

Changes to valuation and revision

The amendments alter how market value guidelines may be estimated and revised:

• State-level estimation is to reflect increases or decreases in market value for each survey number, subdivision number, street or road, as applicable.
• If no general revision occurred in the preceding year, the Valuation Committee may record reasons and instruct that a general revision be undertaken at any time during the calendar year, from a specified date.
• On receiving estimated or proposed market value guidelines, the relevant authority must publish them.
• Valuation sub-committees may meet as often as required to consider the proposed values.
• The existing procedures for estimating market value guidelines also apply to estimating or revising composite value.

Factors for composite valuation

For covered residential properties to which the Tamil Nadu Apartments Ownership Act, 2022 applies, valuation may consider:

• Amenities provided.
• Nearness to markets, bus stands and railway stations.
• Width of the adjoining road.
• Quality of construction.
• Other special features affecting property value.
