Depreciation rates
How depreciation rates are used
Depreciation rates are important for calculating annual or period-by-period adjustments. For more information, see the Depreciation rates (IR265) guide in Forms and guides > .
You can find the depreciation rates for assets acquired:
- after 1 April 1993 in the Depreciation rate finder in Work it out >
- before 1 April 1993 in the Historic depreciation rates (IR267) in the Forms and guides > .
Important
Special rules apply to the depreciation rates for GST adjustments. They are different from the income tax rules explained in Depreciation - a guide for businesses (IR260).
- The date you purchased or used your asset doesn't matter for GST adjustments.
- You can't use the depreciation rates that include either a 20% or 25% loading. These rates are for income tax purposes and don't apply to GST adjustments.
