OCTC Effective Life Determination of Effective life of Depreciating Assets

Legislative Instrument

Explanatory Statement

 

General Outline of Instrument

The authority for making an effective life determination is provided by subsection 40-100(1) of the Income Tax Assessment Act 1997.

 

The proposed Income Tax (Effective life of Depreciating Assets) Amendment Determination 2005 (No 2) would be a legislative instrument for the purposes of the Legislative Instruments Act 2003.

 

Date of effect

This Instrument applies from 1 January 2006.

 

What this instrument is about:

The instrument provides taxpayers with effective lives as a basis to calculate the decline in value (depreciation) of an asset for income tax purposes as determined by the Commissioner for the purpose of section 40-95 of the Income Tax Assessment Act 1997

 

What is the effect of this instrument:

It provides taxpayers with a choice under the Income Tax Assessment Act 1997 for the purpose of measuring a decline in value (depreciation) as a taxpayer can use either an effective life determined by the Commissioner or work out (self-assess) their own effective life.

 

By using the effective life determined by the Commissioner it provides what is referred to as a “safe harbour “life for taxpayers as it provides certainty to the taxpayer that these lives will be accepted by the Commissioner.

 

Background:

The policy of effective life depreciation came into effect on 21 September 1999, when accelerated depreciation was removed. 

 

As part of that policy the Government also endorsed the Review of Business Taxation’s recommendation that the Commissioner of Taxation institute an ongoing revision of the effective life schedule (recommendation 8.5 of A Tax System Redesigned).

 

The Tax Office is undertaking a comprehensive review of the Commissioner’s determinations of effective life.  In doing so, it is taking advice from taxpayers, valuers, industry associations, industry engineers and manufacturers of the assets.

 

The current review is the most comprehensive ever undertaken in terms of the information gathered and the consideration given to different factors.

 

Taxation Ruling TR 2000/18 explains the factors the Tax Office takes into account when making effective life determinations.  Those factors include commercial and technical obsolescence, to the extent it is predictable.  The review is not focusing on the physical life of assets to the exclusion of economic influences on effective life.

 

Ultimately, the Commissioner’s determinations must satisfy the question of how long the depreciating asset can be used by any entity for a taxable purpose.

 

The new determinations in this edition of Taxation Ruling TR 2000/18 do not represent any change in policy.  They represent proper administration of the law.

 

The new determinations have been arrived at by a proper process.  An independent Review Panel has confirmed that sufficient consultation was undertaken.  Any comments on the new determinations should be directed to the Commissioner of Taxation.

 

Consultation:

 

Notifications of the various reviews being conducted are listed on the Tax Office website with an invitation for participation in the reviews.

 

Draft effective lives are also published along with requests for feedback and these drafts are also sent to industry participants, associations etc for comment.  After considering any feedback final effective lives are published in TR2000/18 on the Tax Office website.

 

A panel consisting of external representatives from the CPA Australia, the Corporate Taxpayers Association, as well as the Treasury, the Australian Valuations Office, and the First Assistant Commissioner, OCTC who eventually signs the instrument ensures that a full consultative process has been carried out with all stakeholders when conducting effective life reviews.

 

The final effective lives are also sent to all taxpayers that participated in the review and the determination is also published on the ATO website.
