Edition and the starting point
The third edition was published on 30 January 2026; the first and second editions were dated 2 September 2014 and 8 November 2023. Fixed machinery is machinery attached to land or a building so that it becomes a fixture, often a large machine held by building frames or resting on its own weight.
Fixtures generally form part of the land or building and are subject to property tax under section 6(1). The section 2(3) exclusion applies to specified machinery’s enhancement of annual value. It does not exclude every machine installed in an industrial property.
What section 2(3) excludes
The statutory purposes are making an article or part of it; altering, repairing, ornamenting or finishing an article; and adapting an article for sale. The premises’ enhanced value from qualifying machinery is left out when assessing annual value. Machinery includes the steam engines, boilers and other motive power belonging to it.
The guide notes that the provision was section 2(2) in the 2005 Revised Edition and became section 2(3) in the Property Tax Act 1960 effective from 31 December 2021. The older numbering in case discussions should therefore be read in that context.
Manufacturing context: the First DCS decisions
First DCS Pte Ltd v Chief Assessor and Anor [2007] SGHC 82 distinguishes machines serving manufacturing, processing or industrial purposes from machines serving storage or occupants’ enjoyment of a building. The guide cites escalators, lifts and air-conditioning as examples of the latter. The cited escalator fixture example is People’s Park Chinatown Development v Schindler Lifts [1993] 1 SLR 591.
Chief Assessor and Anor v First DCS Pte Ltd [2008] SGCA 15 endorsed the manufacturing interpretation, tracing the statutory terms to UK textile and factory legislation. The exclusion’s object is to encourage investment in manufacturing machinery, rather than all fixtures.
Direct involvement and expressly included motive power
The First DCS Court of Appeal decision confines the machinery to direct involvement in the specified making or processing activity. Peripheral transportation, distribution and storage of finished goods, raw materials or utilities are outside the exclusion unless expressly included. Treatment of solid, liquid or gaseous manufacturing waste solely for discharge is also peripheral.
Motive power is expressly included by the statutory definition. That inclusion should not be extended into a general assumption that every support component or protective system is exempt.
An article intended for sale: Skyventure
Skyventure VWT Singapore v Chief Assessor and Comptroller of Property Tax [2021] SGCA 40 affirmed the manufacturing-process context. The article must be intended for sale, or be the subject of paid services to make, alter, repair, ornament, finish or adapt it for sale.
The indoor-skydiving wind tunnel altered airflow, but customers paid for an experience; the adapted article remained with the taxpayer. This was not adapting an article for sale within section 2(3)(c). The guide therefore does not equate a paid experience with sale of the processed article.
Buildings and fixtures are a separate category
Buildings and fixtures providing the setting or environment for manufacturing remain taxable. Pan United Marine v Chief Assessor [2008] SGCA 21 held that a structure classified as a building cannot simultaneously be treated as machinery for this exclusion.
Examples include floating dry docks, stacks or chimneys discharging fumes and exhaust from a plant, hoppers, silos and pipe racks. Their presence in a production facility does not alone change their classification.
Non-taxable examples listed in the guide
Direct manufacturing or processing examples include blending tanks; petrochemical or pharmaceutical reactor vessels; milk-powder dryers or drying towers; power-plant turbines, heat exchangers, transformers and switchgear; and district-cooling-plant chillers, condensers and heat exchangers.
Machinery belonging to and supplying motive power to the manufacturing machinery may also fall within the exclusion. The guide gives steam engines, boilers and air compressors performing that role as examples.
Taxable building-service machinery: all listed examples
Service machinery provides essential building safety, occupant enjoyment or proper building operation, and may be reflected in rental value. The list includes lighting; mechanical and electrical installations; electricity generation and supply; air-conditioning, ventilation, cooling or heating; air purification; fire protection; and solar panels.
It also includes lightning protection; security and alarms; pumps and sewage installations; water supply and distribution; and escalators, elevators and other people-moving systems. The guide lists these for their building-service function, not merely because of their equipment names.
Taxable peripheral machinery: all listed examples
Peripheral examples are transportation or distribution systems, including pipelines for finished articles, raw materials, fuel or utilities; weighbridges measuring raw materials or finished articles; and cold rooms preserving those materials or articles.
Other examples are clean rooms providing particle-free, pathogen-free or controlled environments; ventilation, heating or cooling that prevents manufacturing-machine hazards; and overhead or travelling cranes. Protective service machinery for manufacturing equipment can remain peripheral to the direct process.
Function determines the outcome
The guide expressly treats its examples as illustrations. The actual function of a machine or component, rather than its name, label or description, determines whether its enhanced value is excluded or taxable. A cooling device directly performing a manufacturing process is therefore assessed by its function, rather than assumed to have the same treatment as building air-conditioning.
The listed enquiry route is the IRAS website’s Contact Us channel for the Property Tax Division. The article explains this edition and its cases; it does not decide the classification of an unexamined installation.
