What is Accounting Depreciation?

Accounting depreciation is also known as ‘book depreciation’ and is prepared in accordance with the Matching concept (Revenues and expenses generated should be recognised and recorded for the same accounting period). Book depreciation is also subjected to accounting guidelines introduced by theInternational Accounting Standards Board (IASB). Accounting standards governing Accounting Depreciation are IAS 4 – Depreciation Accounting and IAS 8 – Accounting Policies, Changes in Accounting Estimates and Errors.

Accounting depreciation is often significantly different to tax depreciation due to two main factors: method of calculation and accounting the useful lifespan of assets.

Methods to Calculate Depreciations

Many methods are available for companies to calculate depreciation. Some widely used ones are,

  • Straight-line method
  • Reducing balance/ Written down value method
  • Sum of digits method
  • Units of production method

Lifespan of Assets

Companies are responsible for estimating the useful lifespan of its assets.

E.g. XYZ Ltd purchases a machine for $ 60,000 with an estimated salvage value of $10,000. The economic useful life of the machine is 10 years. This makes the annual depreciation amount (assuming a straight-line method of depreciation) as $ 5,000. ($60,000-$10,000/10).

Key Difference - Accounting Depreciation vs Tax Depreciation

What is Tax Depreciation?

Tax Depreciation is calculated for the purpose ofincome tax. The main purpose of this calculation is to reduce taxable income. This is based on the Internal Revenue Service’s rules. Taking the same example, IRS may specify that the useful life of the above machine is 8 years, thus for the purpose of tax depreciation, the calculations should be done for an estimated time period of 8 years.

The IRS rules also allow a company toacceleratethe depreciation expense. This means charging more depreciation in the first few years and less depreciation in the later years of the asset’s life. This saves income tax payments in the first few years of the asset’s life but will result in more taxes in the later years. Companies that are profitable find the accelerated depreciation to be more attractive.

Due to this reason, the company has to maintain two types of records fordepreciation: one for thefinancial reportingpurpose and the other for income tax purposes.

Furthermore, companies may have different depreciation policies, which tax depreciation is treated differently. For example,

  • If the asset is purchased in the middle or towards the end of the year no depreciation will be charged for that year
  • Full year’s depreciation will be charged in the year of purchase
  • No depreciation will be charged on the year of disposing of the asset

Disposing Fixed Tangible Assets

At the end of the economic useful life, the asset can be disposed for a monetary value. The company will either make a gain or a loss upon disposal, which is recognised in theincome statement.
