Under U.S. GAAP, the R&D costs that can be capitalized fall into a short list: tangible assets that have a use beyond a single project, certain software development costs incurred after specific milestones, and in-process research and development picked up when you acquire another business. Everything else in ASC 730’s scope gets expensed as incurred, even when the project looks promising.
The Default Rule: Expense as Incurred
ASC 730-10-25-1 is blunt: all research and development costs within the standard’s scope “shall be charged to expense when incurred.”1Financial Accounting Standards Board. FASB ASC Topic 730 – Research and Development That applies whether or not the project eventually succeeds. A pharmaceutical company that spends $200 million developing a blockbuster drug still runs every dollar of that internal R&D through the income statement in the period incurred. The premise behind the standard is that future economic benefits from R&D are too uncertain to record as an asset.
The scope is broad. Salaries for scientists and engineers on R&D work, materials consumed in prototyping and testing, payments to outside contractors for specialized lab work, and a reasonable allocation of indirect costs like utilities and facility depreciation all flow through R&D expense.1Financial Accounting Standards Board. FASB ASC Topic 730 – Research and Development General and administrative overhead not clearly tied to R&D stays out.
One boundary worth noting up front: routine improvements to existing products don’t fall under ASC 730 at all. Ordinary manufacturing tweaks and periodic quality adjustments are operating expenses, not R&D.2KPMG. Research and Development Handbook ASC 730 targets the planned search for new knowledge and the translation of that knowledge into new products or processes before commercial production begins.
Tangible Assets With Alternative Future Use
Physical assets bought for R&D work can be capitalized if they’re flexible enough to be reused. When equipment, a building, or another tangible asset has what the standard calls “alternative future use,” the company puts it on the balance sheet and depreciates it over its useful life like any other fixed asset. Only the depreciation allocated to R&D periods hits the R&D expense line.2KPMG. Research and Development Handbook
Alternative future use means the asset could serve another R&D project, shift into commercial production, or be sold. General-purpose lab equipment is the standard example, as is a testing facility multiple teams can use over several years.
The opposite scenario is where the immediate expense lands. If an asset has no use beyond a single R&D project, its entire cost must be expensed at acquisition.2KPMG. Research and Development Handbook A custom mold built exclusively for one prototype that will be scrapped after testing is the classic example. The judgment rests on the asset’s inherent flexibility and marketability, not on management’s stated plans, and auditors will push back on alternative-future-use claims for assets that realistically have none.
Software Developed for Sale or Lease
Software intended for external markets follows ASC 985-20, which draws a clear line. Costs before technological feasibility are expensed. Costs after that point, up to the date the product is available for general release, are capitalized.
Technological feasibility is established when planning, designing, coding, and testing are complete enough to confirm the product can meet its design specifications. In practice, that means completing either a detailed program design or a working model. The choice isn’t an accounting policy election; it depends on how the company actually develops the product. If the process uses a detailed program design, the company must complete that design, confirm consistency with product specifications, and resolve any high-risk development issues through coding and testing. If no detailed program design exists, the company needs a completed working model that has been tested against the product design.3PwC. Establishing Technological Feasibility
Once that threshold is crossed, the company capitalizes coding costs, testing costs, payroll for the developers doing that work, and outside services directly tied to producing the software. These accumulate on the balance sheet until general release. After release, maintenance and customer support costs are expensed. The capitalized software asset is then amortized using the greater of straight-line amortization over the product’s estimated life or the ratio of current revenue to total projected revenue.4U.S. Securities and Exchange Commission. Note 1 – Summary of Significant Accounting Policies: Software Development Costs
A practical reality: many software companies reach technological feasibility so close to release that the capitalization window is very short. Some effectively expense all software development costs because the period between working model and shipping is measured in days or weeks. That’s a legitimate outcome under the standard, and it explains why major tech companies often show minimal capitalized software on the balance sheet.
Software Developed for Internal Use
Internal-use software follows a separate standard, ASC 350-40, which uses a three-stage framework to determine when capitalization starts and stops.5Crowe LLP. How to Apply ASC 985-20 and ASC 350-40 for Software Costs Under the current rules:
- Preliminary project stage — conceptual planning, evaluating alternatives, and deciding whether to proceed. All costs are expensed.
- Application development stage — coding, configuration, hardware installation, and testing. Costs directly tied to development work are capitalized, including payroll for internal employees and fees paid to outside developers.
- Post-implementation stage — maintenance, training, and minor enhancements after the software is substantially complete and ready for use. These costs are expensed.
Certain costs are excluded from capitalization even during the application development stage. Training costs, data conversion expenses (other than software purchased specifically for the conversion), and general and administrative overhead all get expensed as incurred.6Financial Accounting Standards Board. FASB ASC Subtopic 350-40 – Internal-Use Software Once the software is operational, the capitalized asset is amortized on a straight-line basis over its estimated useful life.
Cloud Computing and SaaS Implementation Costs
A hosting arrangement where the customer doesn’t have the right to take possession of the software is treated as a service contract, not a software license. Subscription fees and ongoing service payments are expensed as incurred, because the customer doesn’t own or control the underlying software.
Implementation costs are the piece that can be capitalized, and only if they fall within the application development stage under ASC 350-40. Capitalizable implementation costs include custom coding and configuration, system integration, and payroll for employees directly working on the implementation project. Training, data conversion that isn’t essential to the system’s functionality, and ongoing maintenance and support fees stay on the income statement. The capitalized implementation costs are amortized over the term of the hosting arrangement, including any reasonably certain renewal periods.
A common example: a business spending $500,000 to configure and integrate a new cloud ERP system may capitalize those configuration costs, while a $200,000-per-year subscription fee goes straight to the income statement. Getting the classification right depends on whether the contract gives the customer the right to take possession of the software without significant penalty and whether it’s feasible to run the software independently of the vendor.
In-Process R&D Acquired in a Business Combination
When one company acquires another in a business combination, ASC 805 overrides the ASC 730 expensing rule for the target’s in-process research and development. Acquired IPR&D is capitalized at fair value on the acquisition date and recorded as an indefinite-lived intangible asset, regardless of whether it would otherwise have alternative future use.
The IPR&D asset keeps its indefinite-life classification until the underlying project is completed or abandoned. If completed, the company reclassifies it as a finite-lived intangible asset and begins amortizing it. If abandoned, the remaining balance is written off as an impairment charge. While the asset sits as indefinite-lived, it isn’t amortized, but it must be tested for impairment at least annually.
This treatment creates an asymmetry worth understanding. A company developing a drug internally expenses every dollar of R&D along the way; an acquirer buying that same company capitalizes the identical pipeline at fair value. Acquired R&D shows up on the balance sheet, while homegrown R&D never does.
Coming Change: ASU 2025-06 for Internal-Use Software
In 2025, the FASB issued ASU 2025-06, which overhauls the internal-use software model in ASC 350-40.7Financial Accounting Standards Board. Accounting for and Disclosure of Software Costs The standard is effective for fiscal years beginning after December 15, 2027, with early adoption permitted.8Deloitte Accounting Research Tool. FASB Amends Guidance on the Accounting for and Disclosure of Software Costs
The biggest shift is the elimination of the three development stages. Instead of tracking movement from the preliminary stage to the application development stage, capitalization begins when two conditions are met: management has authorized and committed to funding the project, and it’s probable the project will be completed and the software will perform its intended function. The FASB also introduced a “significant development uncertainty” concept. If a project involves that kind of uncertainty, it isn’t considered probable of completion until the uncertainty is resolved, which pushes costs to the income statement for longer.
The ASU also folds the website development cost guidance from ASC 350-50 into ASC 350-40, eliminating the separate standard. It does not change the rules for external-sale software under ASC 985-20.
A Note on Tax Treatment
The tax rules for R&D spending are separate from the GAAP accounting treatment and shouldn’t be conflated. For tax years beginning after December 31, 2024, new Section 174A of the Internal Revenue Code allows immediate deduction of domestic research and experimental expenditures, or at the taxpayer’s election, capitalization and amortization over at least 60 months.9Grant Thornton. Permanent Full Expensing for U.S. Research in OBBBA Foreign R&E costs must still be capitalized and amortized over 15 years, starting at the midpoint of the tax year the costs are incurred.10Office of the Law Revision Counsel. 26 USC 174 – Amortization of Research and Experimental Expenditures The scope of costs covered by Section 174 is also broader than ASC 730, so the GAAP R&D expense figure is a starting point for the tax calculation, not the answer.
