Key takeaways

  • IAS 16 governs property, plant and equipment (long-term physical assets).
  • Assets start at cost, including the costs to get them ready for use.
  • Their cost is spread over their useful life through depreciation.
  • They can be held at cost or revalued to fair value.

What is IAS 16?

IAS 16, Property, Plant and Equipment, sets out how to account for tangible long-term assets, machinery, vehicles, fixtures, buildings, that a business uses over several years.

Initial cost

An asset is first recorded at cost, which includes the purchase price plus the costs of getting it ready to use, such as delivery and installation.

Depreciation

Because the asset is used up over time, its cost is spread across its useful life as depreciation, an expense each period. This matches the cost to the years that benefit from the asset.

Cost vs revaluation model

A business can keep assets at cost less depreciation, or choose the revaluation model, carrying them at fair value with regular revaluations. Most small businesses use the simpler cost model.

Worked example

You buy a machine for £12,000 with a 5-year useful life:

Annual depreciation (straight line) = £12,000 ÷ 5 = £2,400 per year
After 2 years its book value = £12,000 − £4,800 = £7,200.

Frequently asked questions

What is depreciation?

The way an asset's cost is spread over the years it is used, recognised as an expense each period rather than all at once.

Is depreciation the same as capital allowances?

No. Depreciation is an accounting expense; capital allowances are the tax version HMRC allows. They are calculated differently.

Does IAS 16 apply to small companies?

Full IFRS reporters apply IAS 16. UK GAAP (FRS 102/105) has equivalent rules for fixed assets and depreciation.
