Defered tax

Hi I have a very small question on deferred tax, I’m getting the hang of it….almost.

If an asset has fair value of £1,500 and tax base of £1,000. ( corporate tax rate 30% )

Would this mean that there is a tax deferred liability of 500×30%=£150

My reasoning is that if we sold the asset today at fair value £1,500 we would capitalise a gain vs the tax base (£1,000) of £500×30% = £150 therefore this will become a liability awaiting to arise assuming the sale proceeds.

Thanks alot,
