Appendix: 16. This Ruling is issued as part of an ongoing review of the Commissioner's effective life determinations. 17. Tables A and B are periodically updated to incorporate further effective life determinations made by the Commissioner as a result of effective life reviews. We consult industry bodies and interested taxpayers during effective life reviews. In some instances, we use reports prepared by independent consultants. An independent review panel also checks each review process to confirm the level of industry consultation was appropriate. The panel typically comprises representatives from: 18. The Commissioner has made a determination of the effective life of certain depreciating assets in Tables A and B to take effect from 1 July 2022. The Table A assets in the new determination are assets used in the following industries and industry activities: 19. The new determination also amends some entries in Table A and inserts new entries in Table B. These changes are also incorporated into the tables. 20. If a particular asset is not listed in either Table A or B, it means the Commissioner has not made a determination of its effective life; it does not indicate that the asset is not a depreciating asset. In some cases, it is due to the difficulties in determining an appropriate effective life that accurately reflects all the facts and circumstances particular to that asset. In these cases, you need to work out its effective life yourself (see section 40-105 and paragraphs 47 to 50 of this Ruling). 21. An asset that is a depreciating asset for a particular taxpayer or industry may not necessarily be a depreciating asset for another taxpayer or industry. This is typically the case where the asset is an improvement to land. For example, effective lives have been determined for swimming pools in Table B. However, these effective life determinations only apply to the swimming pools that are used as plant in a business. A residential property owner cannot use these effective life determinations because a swimming pool used in a residential rental property setting is not plant (and not a depreciating asset) to which Division 40 applies. | How does the Commissioner determine the effective life of a depreciating asset?: 22. The Commissioner makes a determination of the effective life of a depreciating asset by estimating the period (in years, including fractions of years) the asset can be used by any entity for a specified purpose. If relevant for the asset, the Commissioner: 23. In determining an effective life, the Commissioner considers the factors listed in paragraph 24 of this Ruling. The list is not exhaustive. For example, in determining the effective life of horticultural plants, issues such as crop management techniques (crop regeneration and topworking or reworking where trees are cut back to the stump) were taken into account along with the listed factors. Where appropriate, each factor is considered based on historical information and future expectations. No single factor is necessarily conclusive and the relative importance of each varies depending on the asset. 24. The factors the Commissioner considers include: | Physical life: 25. An asset can be used while it continues to have a physical life; that is, until it is physically exhausted. 26. An effective life determination is an estimate of the period the asset can be used by any entity for a specified purpose. Often an asset is not used for a specified purpose for the whole of its physical life. For example, an asset may be retired from use for a specified purpose but be retained as a source of spare parts. In this instance, the effective life ends when the asset is retired. 27. An asset's physical life can be seen as the outer limit of its effective life. This is a useful starting point for analysing the factors to be considered in determining the effective life of the asset. | Manufacturing specifications and engineering information: 28. The effective life of a new asset cannot be based solely on evidence of past use of the asset. The current design may differ for various reasons including advances in technology and different construction materials. Analysing manufacturing specifications and engineering information for the new asset is important when estimating its effective life. | Use of the asset in a particular industry: 29. How intensively an asset is used in an industry would have a direct impact on the asset's effective life. In establishing the industry norm, the relevant industry is consulted where possible. | Use of the asset in different industries: 30. The use of an asset in different industries is another important factor. For example, using a car in the taxi industry would subject the car to more wear and tear than using a car in another industry. The effective life determined by the Commissioner in each industry would be different, reflecting that different use. | Industry standards: 31. Industry standards and regulations may dictate when a particular asset must be retired from use in an industry. 32. There may also be industry standards and regulations that set the level of repairs and maintenance that must be carried out. | Repairs and maintenance: 33. It might be suggested that the life of an asset can be extended indefinitely if there is unlimited expenditure on repairs and maintenance. However, paragraph 40-100(6)(b) requires the Commissioner to assume that an asset will be maintained only in reasonably good order and condition. Therefore, an asset's effective life is generally limited by the period it is economic to maintain the asset, even though it is still possible to continue repairs and maintenance to keep it operational. 34. An asset can be subject to such a level of repair and maintenance that it has been wholly or substantially physically replaced. In those circumstances, the effective life of the asset is considered to have ended and a new asset to have come into place. | Retention period: 35. The effective life of an asset is the total period it can be used by any entity for a specified purpose. The retention period is the time a particular taxpayer expects to hold a depreciating asset for any purpose. For example, it is common practice in some businesses to dispose of a car after it has been driven a pre-determined number of kilometres. That would be the retention period for that taxpayer. The effective life of the car, however, would end only when the car cannot be used by any taxpayer for a specified purpose. | Obsolescence: 36. The Commissioner considers obsolescence when determining the effective life of an asset. 37. An asset may become obsolete because of commercial or technological reasons. 38. Commercial obsolescence may occur if demand for the goods produced by the asset stops because consumers choose not to buy them or government regulation affects market demand. It may also occur if the raw material the asset processes becomes unavailable. 39. Technological obsolescence may occur when technology advances and another asset becomes better suited for the relevant purpose for which an existing asset is used. Even so, an asset's effective life does not necessarily end with each technological advance. A taxpayer can still use an asset for a specified purpose even though a newer model exists. 40. There are 2 types of commercial and technological obsolescence - one can be predicted at the time the asset is first used and one is unpredictable and emerges later. Unpredictable obsolescence cannot be taken into account when estimating effective life. Predicted obsolescence would only be taken into account if it is expected with a high level of certainty across a majority of users. 41. Taxpayers faced with predicted obsolescence that would arise only because of their particular use of the asset may choose to work out the effective life of the asset themselves, rather than adopt the effective life determined by the Commissioner. | Scrapping or abandonment practices: 42. Once a taxpayer has scrapped or abandoned an asset, it is presumed it can no longer be used by anyone for a specified purpose. The scrapping of an asset can demonstrate that the asset is either physically exhausted or obsolete. The abandonment of an asset can demonstrate that it is too difficult or costly to remove it from its place of operation. 43. This factor is only relevant to the Commissioner's determination of the effective life of an asset if a general scrapping or abandonment practice can be established across users of the asset. | Lease periods: 44. Effective life is the period a depreciating asset can be used by any entity for a specified purpose, so it is unlikely that an asset would be leased for a period greater than its effective life. This generally suggests that the effective life of an asset is no shorter than the period it is leased. | Financial analysis: 45. As with lease periods, economic or financial analysis indicating the period over which an asset is intended for use suggests the effective life is no shorter than that period. In many instances, the analysis may only reflect the capital cost recovery period or the term of a contract, when the asset may in fact be used for a specified purpose by any entity for a much longer time. | Market value: 46. The defining character of a depreciating asset is that its value actually falls, or is expected to fall, over time. Therefore, analysing the decline of market value of an asset class is important to the determination of the asset's effective life. | Working out your own effective life: 47. The Commissioner only takes account of normal industry practice when estimating effective life. Taxpayers who choose to self-assess, however, can take account of their own particular circumstances of use (see section 40-105). 48. The Commissioner only makes determinations of the effective life of new assets. If you purchase a second-hand asset where its condition justifies a shorter life than that determined by the Commissioner, you can self-assess. A taxpayer who self-assesses the effective life of a depreciating asset acquired after 11:45 am, by legal time in the Australian Capital Territory, on 21 September 1999 is no longer required to assume that it is new. 49. Taxpayers can recalculate the effective life of a depreciating asset if the effective life used is no longer relevant because of changed circumstances relating to the use of the asset (see section 40-110). An example could be unpredicted obsolescence or more or less rigorous use than anticipated. 50. For some assets, you do not have a choice to work out the effective life yourself or use an effective life determined by the Commissioner. In addition, the effective life of these assets cannot be recalculated. The choice is not generally available: | Capped lives: 51. Where a capped life for a depreciating asset is available (see section 40-102), the asset is marked in Tables A or B with a hash (#) in the third column. 52. From the 2012-13 income year, a capped life of 10 years is available for eligible shipping vessels but only if certain conditions are met (see table item 10 of subsection 40-102(4) and subsection 40-102(4A)). 53. These conditions mean that not all shipping vessels listed under the Water transport and support services (48100 to 48200 and 52110 to 52190) sub-category in Table A will be eligible for the capped life at any given time. 54. For this reason, no shipping vessels have been marked with a hash (#) in the third column of Table A as would occur with other assets that have no additional eligibility requirements for a capped life. 55. Taxpayers need to determine if a particular shipping vessel they hold meets the eligibility requirements of subsections 40-102(4) and (4A) to determine if the capped life can be applied. | Decline in value calculation: 56. The effective life shown in Tables A or B is a component of the formula under which the decline in value of the depreciating asset is calculated. [5] | New and reviewed effective lives: 57. Assets already reviewed as part of the ongoing review of the Commissioner's effective life determinations are marked with an asterisk (*) in the third column of Tables A and B. | Important terms and definitions in Tables A and B: 58. The terms 'freestanding' and 'fixed' describe certain residential rental property assets listed in Table A. 'Freestanding' is also used in Table B for 'light fittings and freestanding lights'. For the purposes of the determination of the effective life of such assets, the terms have the following meanings: 59. The terms 'environmental control structure' and 'protective structure' are used to describe certain agricultural assets listed in Table A. For the determination of effective life of such assets, the terms have the following meanings: 60. The terms 'including', 'includes' and 'incorporating' have been used in describing certain assets in Tables A and B. Where used, the terms have the following meanings: 61. The terms 'hire cars' and 'rental cars' have been used to describe certain assets in Tables A and B.

If this Ruling applies to you, and you correctly rely on it, we will apply the law to you in the way set out in this Ruling. That is, you will not pay any more tax or penalties or interest in respect of the matters covered by this Ruling. | Date of effect: 15. This Ruling applies from 1 July 2022. However, the Ruling does not apply to taxpayers to the extent that it conflicts with the terms of a settlement of a dispute agreed to before the date of issue of the Ruling. | Freestanding - are items designed to be portable or movable; any attachment to the premises is only for the item's temporary stability. | Fixed - are items annexed or attached by any means (for example screws, nails, bolts, glue, adhesive, grout or cement) but not merely for temporary stability. | Environmental control structure - is a structure designed to provide a protective environment within which the operator is able to monitor and manipulate factors influencing the growing environment. This includes factors such as temperature, humidity, air movement, light, water and pests to enable the greatest efficiency in producing the desired product. | Protective structure - is a structure used primarily and principally for protecting a growing product from one or more natural elements such as sun, hail, birds and wind. | Including or includes - when an entry is described as 'including' or 'includes' other items, these other items are separate assets, each with the same effective life. For example, the entry 'Refrigeration assets (including chillers, compressors, condensers, evaporative coolers and pumps)' indicates that chillers, compressors, condensers, evaporative coolers and pumps are separate assets within the class of refrigeration assets, all of which have the specified effective life. | Incorporating - when an entry is described as 'incorporating' other items, these other items are not separate assets but are merely components of the one single asset being described. For example, the entry 'Conveyor systems (incorporating structures, belts, gearboxes and motors)' indicates that the structures, belts, gearboxes and motors are components of the one asset, the conveyor system. | Hire car - is a passenger car hired with a driver, not being a taxi. | Rental car - is a passenger car hired, leased or rented for short-term use without a driver. | AGRICULTURE,

Previous rulings: 6. This Ruling replaces Taxation Ruling TR 2021/3 Income tax: effective life of depreciating assets (applicable from 1 July 2021), which is withdrawn from 1 July 2022. Where the Commissioner's views in that Ruling still apply, they are incorporated into this Ruling. | Effective life determination | 7. The Commissioner has made a determination of the effective life of certain depreciating assets, which takes effect from 1 July 2022. This determination has been incorporated into Tables A and B of this Ruling. | 8. The date from which an effective life determined by the Commissioner applies is set out in the fourth column of Tables A and B. | Effective life applicable | 9. If you first use a depreciating asset or have it installed ready for use within 5 years of the time (the relevant time): | the effective life that applies is the one in force at the relevant time (see section 40-95). | 10. If you do not start to use a depreciating asset or have it installed ready for use within the 5-year period, the effective life that applies is the one in force at the date you first use the depreciating asset or have it installed ready for use for any purpose (see section 40-95). | How to use Tables A and B | 11. Table A is an industry category table. It lists assets that are specific to a particular industry or for which a particular effective life is appropriate because of the way the asset is used in that industry. Industry headings in Table A are generally drawn from the classification subject categories in the Australian and New Zealand Standard Industrial Classification (ANZSIC) codes. | 12. Table B is an asset category table which covers assets generally. | 13. You must be satisfied that an asset is a depreciating asset [4] before using an effective life determination in either Table A or B. An asset that is a depreciating asset for a particular taxpayer or industry may not necessarily be a depreciating asset for another taxpayer or industry. | 14. If a particular asset is not listed in either Table A or B, it means the Commissioner has not made a determination of its effective life. You will need to work out its effective life yourself (see section 40-105 and paragraphs 47 to 50 of this Ruling). | To find an asset for a particular asset category, go to Effective lives (Industry category) | To find an asset using an alphabetical listing, go to Effective lives (By asset)
