36. Deferred and current tax

(a) Deferred tax

(i) Net deferred tax assets/(liabilities)

Tax recognised in Other comprehensive income is in respect of the remeasurement of post-employment benefit assets and obligations.

(ii) Movements in gross deferred tax assets and liabilities

These movements do not take into consideration the offsetting of assets and liabilities within the same tax jurisdiction. Items classified as Other assets in the above analyses predominantly relate to future tax benefits deferred in line with local tax laws.

(iii) Other information on deferred tax assets and liabilities

As set out in note 5, there are a number of critical judgments in assessing the recognition of deferred tax assets. The Group has not recognised deferred tax on losses of US$641m (2021: US$581m) that could be utilised against future taxable income or on US$265m (2021: US$282m) in respect of capital losses that could be utilised against future taxable gains. While these losses are available indefinitely, they have arisen in undertakings in which it is not currently anticipated that future benefit will be available from their use. The capital losses arising on investments are available for use within five years, and future taxable gains against which the capital losses could be utilised are not currently anticipated.

There are retained earnings of US$9,699m (2021: US$8,980m) in subsidiary undertakings which could be subject to tax if remitted to Experian plc. No deferred tax liability has been recognised on these earnings because the Group is in a position to control the timing of the reversal of the temporary difference and it is probable that such differences will not reverse in the foreseeable future. Given the mix of countries and tax rates, it is not practicable to determine the impact of such remittance.

During the current year the main rate of UK corporation tax was 19% (2021: 19%). Deferred tax is recognised at the rate prevailing when temporary differences are expected to reverse.
