Research and development (R&D) activities drive innovation and long-term value creation for many organizations, but they introduce unique challenges in financial reporting. Accounting standards set distinct rules for the recognition, measurement, and disclosure of R&D costs, with significant differences between US GAAP and IFRS, especially regarding internally developed intangible assets.
Definition and Classification of R&D Activities
Research: Original and planned investigation undertaken to gain new scientific or technical knowledge and understanding.
Development: Application of research findings to a plan or design for the production of new or substantially improved products, processes, or services before commercial production begins.
These activities may include laboratory research, prototype design, pilot plants, product testing, and the construction of preproduction models.
US GAAP: Expense as Incurred
Under US GAAP (ASC 730), all research and development costs must be expensed as incurred. There is no provision for the capitalization of internally generated R&D, with a few exceptions for software development (addressed separately under ASC 350-40 and ASC 985-20).
Journal Entry Example:
Dr. Research and Development Expense
Cr. Cash/Accounts Payable
This policy prioritizes immediate recognition of costs due to the uncertainty of future economic benefits from R&D efforts.
IFRS: Capitalization of Development Costs
IFRS (IAS 38) requires a distinction between research and development phases:
Research phase: All costs are expensed as incurred.
Development phase: Costs may be capitalized as an intangible asset only if specific criteria are met, including technical feasibility, intent and ability to complete, probable future economic benefits, availability of resources, and reliable measurement of costs.
Development costs are capitalized once all criteria are satisfied; otherwise, they remain expensed.
Software Development Costs
US GAAP: Internal-use software development costs may be capitalized after the preliminary project stage; costs prior to this stage are expensed.
IFRS: Follows IAS 38 principles for distinguishing research and development phases in software projects.
Disclosure Requirements
Both frameworks require companies to disclose:
Total R&D costs expensed during the period
Accounting policies for R&D and internally generated intangibles
Capitalized development costs, if applicable (under IFRS)
Description of projects if material to the financial statements
These disclosures help users assess the impact of R&D on current earnings and potential future value.
Amortization and Impairment (IFRS Only)
Capitalized development costs are amortized over their useful life, beginning when the asset is available for use. These assets are also subject to impairment testing if indicators of impairment arise.
Relevant Accounting Standards
US GAAP: ASC 730 – Research and Development
IFRS: IAS 38 – Intangible Assets

US GAAP | Expense as incurred | Expense as incurred | Capitalize after feasibility |
IFRS | Expense as incurred | Capitalize if criteria met | Capitalize if criteria met |
