IFRS® Accounting Standards

Deferred Tax Related to Assets and Liabilities Arising from a Single Transaction (Amendments to IAS 12)


The Accounting Standards Board (AcSB) is participating in the International Accounting Standards Board’s (IASB) project to amend IAS 12 Income Taxes.

The proposed amendment relates to the recognition of deferred tax when an entity accounts for transactions, such as leases or decommissioning obligations, by recognizing both an asset and a liability. The objective of this amendment is to narrow the initial recognition exemption in paragraphs 15 and 24 of IAS 12, so that it would not apply to transactions that give rise to both taxable and deductible temporary differences, to the extent the amounts recognized for the temporary differences are the same.

The AcSB’s due process includes:

  • ensuring that Canadian entities’ financial reporting needs are considered by the IASB; and
  • issuing the AcSB’s own exposure draft on each IASB proposal.

Subject to the responses to the AcSB’s exposure draft on whether the IASB’s proposals are appropriate for application in Canada, the AcSB expects that the amendments will be incorporated into Canadian GAAP in accordance with the AcSB’s strategy of adopting IFRS® Standards for publicly accountable enterprises.

AcSB Response – Deferred Tax Related to Assets and Liabilities Arising from a Single Transaction (Amendments to IAS 12)

On November 12, 2019, the AcSB submitted a comment letter responding to the IASB’s Exposure Draft issued in July 2019. The letter agrees with the intent of the proposals, but recommends that the drafting of the amendments should be revised to better communicate the guidance to stakeholders. Due to the complexity of this topic, the AcSB also recommends that illustrative examples be provided in IAS 12 to demonstrate the application of the proposed guidance.
