Investopedia cited below explains it well. Your context speaks explicilty of IFRS and IAS which uses this term. So I would definitely use it here (at least on the basis of what I can see) However it covers two very similar things "where a business has overpaid taxes or taxes paid in advance". In effect it covers any situation where the tax people owe you money which you can recover in a future year. In a different context you might want to talk about prepaid taxes, or explain with deferred tax assets for taxes paid in advance.

A deferred tax asset is an asset on a company's balance sheet that may be used to reduce its taxable income. It can refer to a situation where a business has overpaid taxes or taxes paid in advance on its balance sheet. These taxes are eventually returned to the business in the form of tax relief, and the over-payment is, therefore, an asset for the company.
