(1) Estimated production capacity or physical output of fixed assets.
(2) tangible loss of fixed assets, such as wear and tear in the use of equipment, natural erosion of buildings, etc.
(3) the intangible loss of fixed assets, such as the technical level of existing assets is relatively outdated due to the progress of new technologies, and products are outdated due to changes in market demand. (4) Laws or similar restrictions on the use of fixed assets.
According to the new enterprise income tax law, the depreciation period of fixed assets stipulates:
Article 60 Unless otherwise stipulated by the competent departments of finance and taxation of the State Council, the minimum depreciation period of fixed assets is as follows:
(1) Buildings and buildings are production equipment such as airplanes, trains, ships, machines and machinery for 20 years, appliances, tools and furniture related to production and business activities for 65,438+00 years, vehicles other than airplanes, trains and ships for 5 years and electronic equipment for 4 years. Provisions on the residual rate of fixed assets
Article 31 of the Provisional Regulations of People's Republic of China (PRC) on Enterprise Income Tax and its detailed rules for implementation: If the residual value ratio is less than 5% of the original price, it shall be determined by the enterprise itself. According to Article 2 of the Notice of State Taxation Administration of The People's Republic of China on Doing a Good Job in the Follow-up Management of Cancelled Enterprise Income Tax Examination and Approval Projects (Guo Shui Fa [2003] No.70), the proportion of residual value of fixed assets is unified at 5%.
According to Article 33 of the Detailed Rules for the Implementation of the Income Tax Law for Enterprises with Foreign Investment and Foreign Enterprises, the residual value rate of fixed assets of enterprises with foreign investment is generally 10%. Article 59 of the Regulations for the Implementation of the Enterprise Income Tax Law of People's Republic of China (PRC) (the State Council Order No.512, 2007) is allowed to deduct the depreciation of fixed assets calculated by the straight-line method. The enterprise shall calculate the depreciation from the next month when the fixed assets are put into use; Depreciation of fixed assets that have ceased to be used shall stop from the next month of the month of cessation of use. An enterprise shall, according to the nature and use of fixed assets, reasonably determine the estimated net salvage value of fixed assets. Once the estimated net residual value of fixed assets is determined, it shall not be changed.
Legal basis: Article 32 of the Enterprise Income Tax Law of People's Republic of China (PRC). If it is really necessary to accelerate the depreciation of fixed assets of an enterprise due to technological progress and other reasons, the depreciation period may be shortened or accelerated depreciation may be adopted. It can be seen that the new tax law no longer stipulates the proportion of the residual value rate of fixed assets, but gives the right to determine the residual value rate of fixed assets to enterprises, but emphasizes a rationality, requiring enterprises to reasonably determine the estimated net residual value of fixed assets according to their own production and operation conditions and the nature and use of fixed assets.
