Question about tax charge

Dear all,
Could u help me, please?

In Promugate’s trial balance as at 31/12/2015 there is a liability in respect of deferred tax of $38.4 million and current liability in respect of current tax $5.4 million

During the year Promugate’s taxable temporary timing differences increased by $20 million of which $12 million related to the revaluation of Promugate’s property. The deferred tax relating to this revaluation shoul be charge to P/L. The income tax rate 20%

No provision has not been made for the income tax liability based on this year’s profits not including the revaluation mentioned above. The directors have estimated the liability to be region of $22.8 million.

What will be tax charged in the P/L for year ended 31/12/2015?
