Taxpayers must depreciate all depreciable property, other than "excluded depreciable property", by applying the "basic economic depreciation rates" (or general depreciation rates). These rates are set out in Determination DEP1, which was issued in 1993. Since DEP1 was issued, we have issued further general determinations amending DEP1 and setting new asset classes and general depreciation rates.
