Go deeper+2 deeper insights · +1 point of attention

The tax base is the value of an item 'in the eyes of the tax authority'. For an asset: what will be deductible when the entity recovers its carrying amount (or the carrying amount itself if those benefits are not taxable). For a liability: the carrying amount less what will be deductible later; for revenue received in advance: the carrying amount less what will not be taxable later. Some items have a tax base without being in the statement of financial position; on consolidation, the base is read from the relevant tax return.
