IAS 38 Intangible Assets: The Complete Compliance Guide

What Is IAS 38?

IAS 38 Intangible Assets is the International Accounting Standard that governs how entities recognise, measure, and disclose intangible assets on their balance sheets. It sets the bar for when an intangible asset may be recorded as an asset rather than expensed immediately, and prescribes the ongoing measurement and amortisation treatment throughout the asset's life.

The standard applies to all intangible assets not covered by a more specific standard, such as goodwill from business combinations (IFRS 3), financial instruments (IFRS 9), mineral rights (IFRS 6), or insurance contract assets (IFRS 17).

For a broader overview of IAS 38 recognition and measurement principles, see our companion article: IAS 38 Explained: Recognition and Measurement of Intangible Assets. This guide focuses specifically on the compliance requirements, decision frameworks, and practical pitfalls that accountants, auditors, and CFOs encounter when applying the standard.

Recognition Criteria: The Four Tests

For an intangible asset to be recognised on the balance sheet under IAS 38, it must satisfy all four of the following criteria simultaneously. Failure on any single criterion means the expenditure must be expensed.

1. Identifiability

The asset must be identifiable, meaning it is either:

• Separable -- capable of being separated from the entity and sold, transferred, licensed, rented, or exchanged, either individually or together with a related contract, asset, or liability; or
• Arising from contractual or legal rights -- regardless of whether those rights are transferable or separable from the entity.

2. Control

The entity must have the power to obtain future economic benefits from the asset and to restrict the access of others to those benefits. Control is typically evidenced by legal rights (patents, copyrights, trademarks) but can also be established through confidentiality agreements, trade secret protection, or contractual restrictions.

3. Future Economic Benefits

The asset must be expected to generate future economic benefits for the entity. These benefits may take the form of revenue from the sale of products or services, cost savings, or other benefits resulting from the use of the asset.

4. Reliable Measurement of Cost

The cost of the asset must be measurable reliably. For acquired assets, this is straightforward -- the purchase price provides the cost. For internally generated assets, this requires careful tracking of development expenditure from the point at which all capitalisation criteria are first met.

The IAS 38 Recognition Decision Tree

The following decision tree captures the logic that preparers and auditors must apply when assessing whether an intangible item qualifies for balance sheet recognition.

Internally Generated vs Acquired Intangible Assets

This is the most consequential distinction in IAS 38 for practical compliance. The standard treats acquired and internally generated intangible assets very differently.

The Six Development Cost Capitalisation Criteria (IAS 38.57)

Development expenditure may only be capitalised when the entity can demonstrate all six of the following:

This is a critical difference from US GAAP. Under ASC 730, virtually all research and development costs are expensed immediately. Only internal-use software development (ASC 350-40) and software for sale (ASC 985-20) have specific capitalisation provisions under US GAAP. IAS 38's approach can result in significantly higher reported assets and profits for companies with material development programmes.

Measurement: Cost Model vs Revaluation Model

After initial recognition at cost, IAS 38 offers two subsequent measurement models.

Cost Model (Default)

Under the cost model, the intangible asset is carried at cost less any accumulated amortisation and any accumulated impairment losses. This is the model used by the vast majority of entities worldwide.

Revaluation Model (Rare)

Under the revaluation model, the asset is carried at a revalued amount, being its fair value at the date of revaluation less any subsequent accumulated amortisation and impairment losses. However, IAS 38 restricts the revaluation model to intangible assets for which an active market exists.

Comparison of Measurement Models

Useful Life and Amortisation

IAS 38 requires entities to assess whether the useful life of an intangible asset is finite or indefinite. This assessment drives the amortisation treatment.

Finite Useful Life

Assets with a finite useful life are amortised systematically over that life. The amortisation method should reflect the pattern in which the asset's future economic benefits are consumed. If that pattern cannot be determined reliably, the straight-line method is used.

The useful life and amortisation method must be reviewed at least at each financial year end. Changes are accounted for as changes in accounting estimates (IAS 8).

Indefinite Useful Life

An intangible asset has an indefinite useful life when there is no foreseeable limit to the period over which the asset is expected to generate net cash inflows. This does not mean "infinite" -- it means the entity cannot determine a finite life based on analysis of all relevant factors.

Assets with indefinite useful lives are not amortised but are subject to an annual impairment test under IAS 36, and whenever there is an indication of impairment. The indefinite life assessment must be reviewed each period to determine whether events support the continued indefinite classification.

IAS 38 vs IFRS 3: How They Interact

Understanding the interaction between IAS 38 and IFRS 3 Business Combinations is critical for anyone involved in purchase price allocation work.

The Key Relationship

When a business combination occurs under IFRS 3, the acquirer must recognise acquired intangible assets separately from goodwill. IFRS 3 uses a broader recognition gateway than IAS 38 for day-to-day accounting:

This means that an acquirer in a business combination will typically recognise significantly more intangible assets on the balance sheet than the target company recognised itself. Customer relationships, order backlogs, favourable contracts, non-compete agreements, and technology assets that were never on the target's books will be brought onto the acquirer's balance sheet at fair value.

IAS 38 vs FRS 102 Section 18: UK Private Companies

UK private companies report under FRS 102 (UK GAAP) rather than full IFRS. Section 18 of FRS 102 governs intangible assets other than goodwill. While conceptually similar to IAS 38, there are several important differences.

Key Differences

Common IAS 38 Compliance Mistakes

Based on audit findings and common practice errors, these are the compliance failures that trip up even experienced practitioners.

Mistake 1: Capitalising Research Costs

IAS 38.54 is unambiguous: all expenditure on the research phase must be expensed as incurred. The most common error is failing to distinguish clearly between research and development activities, leading to premature capitalisation of costs that belong in the research phase.

Mistake 2: Backdating the Capitalisation Start Date

Development costs may only be capitalised from the date on which all six criteria in IAS 38.57 are first satisfied. Entities sometimes capitalise from project inception or from the date of management's decision to proceed, rather than from the date the sixth criterion is demonstrably met.

Mistake 3: Failing to Review Useful Life Annually

IAS 38.104 requires the useful life and amortisation method to be reviewed at least at each financial year end. Many entities set the useful life at initial recognition and never revisit it, even when circumstances change materially.

Mistake 4: Classifying as Indefinite Without Evidence

Indefinite useful life does not mean the entity simply has not decided on a period. It requires a positive analysis demonstrating no foreseeable limit to the period of benefit. Auditors increasingly challenge indefinite classifications that lack documented supporting analysis.

Mistake 5: Ignoring Impairment Indicators Between Annual Tests

Indefinite-life intangible assets require annual impairment testing, but IAS 36 also requires testing whenever there is an indication of impairment. Entities that only test annually and ignore mid-year indicators (loss of a major customer, regulatory change, technology disruption) are non-compliant.

Mistake 6: Recognising Internally Generated Brands

IAS 38.63 specifically prohibits the recognition of internally generated brands, mastheads, publishing titles, customer lists, and items similar in substance. Despite this, some entities attempt to capitalise brand-building expenditure as an intangible asset.

How Opagio Maps to IAS 38 Requirements

The Opagio Growth Platform helps organisations bridge the gap between the intangible assets that IAS 38 recognises and the broader intangible capital that drives business value.

For IAS 38 compliance, Opagio supports:

• Asset identification using the Opagio 12 Value Drivers framework, which maps to both the CHS economic categories and IFRS 3 recognition classes
• Valuation methodologies including Relief from Royalty, MPEEM, and cost-based approaches aligned with IAS 38 measurement requirements
• Portfolio tracking with audit trails for carrying amounts, amortisation schedules, and impairment indicators
• Useful life monitoring with alerts for annual review requirements

Beyond IAS 38, the platform captures the intangible assets that accounting standards exclude -- assembled workforce, customer loyalty without contracts, institutional knowledge, and organisational culture -- giving management teams a complete picture of intangible capital for strategic decision-making.

Explore the Opagio Growth Platform to see how it supports both compliance reporting and strategic intangible asset management.

Frequently Asked Questions

What intangible assets can be recognised under IAS 38?

Intangible assets that meet all four recognition criteria -- identifiability, control, future economic benefits, and reliable cost measurement -- can be recognised. Common examples include patents, copyrights, software, licences, trademarks (when acquired), customer relationships (when acquired in a business combination), and capitalised development costs. Internally generated brands, mastheads, customer lists, and publishing titles are specifically prohibited.

Can you capitalise development costs under IAS 38?

Yes, but only when all six criteria in IAS 38.57 are met: technical feasibility, intention to complete, ability to use or sell, probable future economic benefits, availability of adequate resources, and ability to measure expenditure reliably. Unlike US GAAP (ASC 730), which generally expenses all R&D, IAS 38 requires capitalisation once these criteria are satisfied. This is a significant difference that can materially affect reported assets and profits.

What is the difference between IAS 38 and IFRS 3 for intangible assets?

IAS 38 governs day-to-day intangible asset accounting (recognition, measurement, amortisation, impairment). IFRS 3 governs the recognition of intangible assets acquired in a business combination. IFRS 3 has a broader recognition gateway: the probability and reliable measurement criteria are automatically satisfied for acquired assets. This means more intangible assets are recognised in a purchase price allocation than a company would recognise on its own balance sheet under IAS 38.

How does IAS 38 differ from FRS 102 Section 18?

The most impactful differences for UK companies are: (1) FRS 102 permits but does not require development cost capitalisation, while IAS 38 requires it when the criteria are met; (2) FRS 102 does not permit the revaluation model for intangibles; (3) goodwill is amortised under FRS 102 but subject to impairment-only testing under IFRS; (4) FRS 102 permits impairment reversal for goodwill, while IFRS does not. See our detailed IAS 38 vs FRS 102 Section 18 comparison.

Does IAS 38 apply in the United States?

No. US companies report under US GAAP, where the equivalent standards are ASC 350 (Intangibles -- Goodwill and Other) and ASC 730 (Research and Development). The most significant difference is that US GAAP expenses virtually all R&D immediately, whereas IAS 38 permits capitalisation of development costs. For a detailed comparison, see our IAS 38 vs ASC 350 comparison.
