The tax expense is the figure in the annual accounts: tax payable plus the change in deferred tax. It is not the tax actually paid for the year. A low share often has an ordinary explanation: losses from earlier years set against the profit, dividends and gains on shares that are tax-free under the exemption method, changes in deferred tax, or tax paid abroad. Some industries also pay special taxes. The share is therefore a question to ask, not an answer. Source: annual accounts from the Brønnøysund Register Centre, our calculations.
