This report states the need, definition, details, and advantages & disadvantages of the accounting and administrative lifespan of research equipment. ‘Accounting lifespan’ refers to a length of period under tax laws, which is set based on the ‘standard useful life’ enacted by the decree of Ministry of Strategy and Planning to clarify tax administration. From an accounting perspective, it is needed in handling tax administration by determining the equipment’s life. On the contrary, ‘administrative lifespan’ represents the length of administrative use until the services are no longer provided. In other words, it means the lifespan from the acquisition of the equipment to the time of normal use. It is necessary in establishing the groundwork for the disposal of equipment after determining its useful lifespan or period of durability as regards its disposal or replacement.
- For more information about the lifespan of research equipment, refer to the ‘Review on the Physical Lifespan of R13 Research Equipment’ published in September 2014.
