Why Deductions Are Necessary


The sole purpose of tax depreciation is to charge to expense a portion of an asset that relates to the revenue generated by that asset. This is called the matching principle, where revenues and expenses both appear in the income statement in the same reporting period, which gives the best view of how well a company has performed in a given reporting period. Tax depreciation is an income tax deduction that allows a taxpayer to recover the cost or other basis of certain property. It is an annual allowance for the wear and tear, deterioration, or obsolescence of the property. Most types of tangible property except land, such as buildings, machinery, vehicles, furniture, and equipment are depreciable. Likewise, certain intangible property, such as patents, copyrights, and computer software is depreciable. Tax depreciation Sydney begins when a taxpayer places property in service for use in a trade or business or for the production of income. The property ceases to be depreciable when the taxpayer has fully recovered the property’s cost or other basis or when the taxpayer retires it from service, whichever happens first.

A taxpayer must identify several items to ensure the proper tax depreciation of a property, including:
  • The depreciation method for the property
  • The class of the asset
  • Whether the property is considered as “Listed Property”
  • Whether the taxpayer elects to expense any portion of the asset
  • Whether the taxpayer qualifies for any “bonus”
  • The depreciable basis of the property
The type of tax depreciation that most closely links the creation of revenue to asset usage is the depletion method, which charges natural resources to expense as they are extracted. Moreover, this option is not available for most types of fixed assets.

The two methods allowed are the Straight Line Method and the Diminishing Method:
Straight Line Method
The straight-line depreciation allows the taxpayers to claim depreciation deduction evenly over the useful life of the asset where the cost of a depreciable asset is deducted evenly over the useful life. In any case the total deductions allowed must not exceed the cost of the asset.

Diminishing Method
The diminishing value depreciation method allows taxpayers to claim the depreciation deduction for a tax year in respect of a depreciable asset and is computed by applying the prescribed depreciation rate against the written down value of the asset at the beginning of the year.

Under no circumstances should we consider depreciation to be an approximation of a decline in an asset's fair value, since fair value can increase or decrease over time and is related to supply and demand, rather than usage. For a depreciation deduction to be allowed, the asset must be used in the business or income-producing activity; the asset must have a determinable useful life; the asset must be used or expected to be used for more than one year.  If we were not to use tax depreciation Sydney at all, then we would be forced to charge all assets to expense as soon as we buy them. This would result in large losses in the months when this transaction occurs, followed by unusually high profitability in those periods when the corresponding amount of revenue is recognized, with no offsetting expense. For this, a company that does not use depreciation will have front-loaded expenses, and will experience extremely variable financial results.
