IAS 8

Overview and Scope

International Accounting Standard 8: Accounting Policies, Changes in Accounting Estimates and Errors (IAS 8) is an international financial reporting standard adopted by the International Accounting Standards Board (IASB).[1] The standard prescribes the criteria for selecting and changing accounting policies, along with the accounting treatment and disclosure of changes in accounting estimates and corrections of prior period errors.[2] IAS 8 is designed to enhance the relevance and reliability of an entity's financial statements and the comparability of those statements over time and with the financial statements of other entities.[3]

Accounting Policies

Accounting policies are the specific principles, bases, conventions, rules, and practices applied by an entity in preparing and presenting financial statements.[4] When an IFRS specifically applies to a transaction, the accounting policy for that item must be determined by applying the relevant standard.[5] In the absence of a specific IFRS, management must use judgment to develop a policy that results in relevant and reliable information.[6] Such judgment should consider the requirements in IFRSs dealing with similar issues and the definitions and recognition criteria in the Conceptual Framework.[7]

Changes in accounting policies are generally applied retrospectively by adjusting the opening balance of each affected component of equity for the earliest prior period presented.[8] An entity shall change an accounting policy only if the change is required by an IFRS or results in the financial statements providing more reliable and relevant information.[9]

Changes in Accounting Estimates

A change in accounting estimate is an adjustment of the carrying amount of an asset or liability resulting from new information or developments.[10] These changes are recognized prospectively by including them in profit or loss in the period of the change and future periods.[11] Unlike accounting policies, changes in estimates do not require the restatement of prior periods because they do not relate to errors.[12]

Prior Period Errors

Prior period errors are omissions from, and misstatements in, an entity's financial statements for one or more prior periods.[13] Material prior period errors must be corrected retrospectively in the first set of financial statements authorized for issue after their discovery.[14] This involves restating the comparative amounts for the prior period(s) presented in which the error occurred.[15]

Booking Examples for IAS 8

The following examples illustrate the difference between prospective and retrospective adjustments.

1. Change in Accounting Estimate (Prospective)

IAS 8 requires prospective application: the new rate applies from the date of change without restating prior years.[16]

Scenario: Cost: $100,000 (Jan 1, 2021) | Original Life: 10 years ($10k/yr) | Revision: On Jan 1, 2024, life reduced to 5 years total (2 years remaining).

Calculation: Carrying Amount (2024): $100,000 - $30,000 = $70,000.[17] | New Depreciation: $70,000 / 2 years = $35,000/yr.[18]

Journal Entry (Dec 31, 2024):

Account Debit Credit Rationale
Depreciation Expense (P&L) $35,000 Applied to remaining book value.[19]
Accumulated Depreciation $35,000 No restatement of 2021–2023.[20]

2. Correction of a Prior Period Error (Retrospective)

Scenario: In 2024, a company discovers it failed to record $50,000 of expenses in 2023.

Event Debit Credit Rationale
Error Correction Retained Earnings (Opening Balance) Accrued Liabilities / Cash The opening balance of equity is adjusted to reflect the error as if it had never occurred.[21]
