Depreciation is calculated using IRD approved rates. The additional depreciation loading of 20% on new assets has been removed for assets acquired from 21 May 2010.
Either the straight line or diminishing value method can be used.
Low value assets (costing $500 or less, GST exclusive) can generally be written off in the year acquired.
From the 2011/12 financial year, no depreciation can be claimed on buildings with a useful economic life of 50 years or more.
