Foundational Understanding: When to Expense vs. Capitalise R&D Costs

For an early-stage biotech, your lab is where value is created, but your profit and loss statement (P&L) often just shows a growing burn rate. This creates a disconnect: you know you’re building a valuable asset, yet the financials only reflect expenses. The question of how to capitalize R&D costs in biotech startups is not merely an accounting exercise; it is a strategic decision that impacts how you report progress to investors, plan for taxes, and tell your company’s financial story. Getting it wrong can lead to costly restatements and missed opportunities. This guide provides a practical framework for navigating the rules in both the US and UK, helping you determine when your lab work transforms from a simple expense into a balance sheet asset. For more context, see the hub on capex, depreciation and intangibles.

At its core, the choice between expensing and capitalising determines where a cost appears in your financial statements. Understanding this distinction is the first step in managing your biotech R&D accounting effectively.

What is Expensing?

Expensing means the cost hits your P&L immediately in the period it is incurred. If you spend $100,000 on early-stage discovery salaries and materials, your net loss for that period increases by $100,000. This is the default treatment for most business costs and is mandatory for all pure research activities.

What is Capitalising?

Capitalising is different. Instead of appearing on the P&L as an expense, the cost is recorded on your Balance Sheet as an “Intangible Asset”. This improves your P&L in the short term because the expense is removed. Later, this asset's value is gradually reduced over its useful life through a non-cash expense called amortisation. A critical distinction here is P&L burn versus cash burn. Capitalising reduces your accounting loss but doesn't change the cash leaving the bank. Sophisticated investors will look at both.

Consider the impact of handling $500,000 in development costs. If you expense the full amount, your R&D expense on the P&L increases by $500,000, directly reducing your net income by that same amount. If you capitalise it, your R&D expense for the period is $0, and an intangible asset of $500,000 is added to your balance sheet, boosting your total assets.

The Core Challenge for Biotech Financial Reporting: When Does Research Become a Capitalisable Asset?

This is the most critical question in biotech R&D accounting and where startups face the biggest pain point: determining the exact point when research activities shift to capitalisable development. The rules and interpretations vary significantly between the United States and the United Kingdom, so understanding your local requirements is essential for compliance.

For US Companies (US GAAP)

The rules are governed by ASC 730, which is prescriptive and strict. First, “Under US GAAP (ASC 730), all research costs must be expensed as incurred.” This is a non-negotiable rule. Research is defined as the search for new knowledge, the exploration of new ideas, and lab work without a specifically defined commercial product in mind.

Development is the application of that research to a specific product plan. According to the standard, development costs can be capitalised only after 'technological feasibility' has been established. This is the trigger point. To meet this high bar, a company must demonstrate all of the following criteria for a project:

  1. The project is clearly defined with specific objectives.
  2. The underlying technology is clearly defined and understood.
  3. Management is committed to funding the project through to completion.
  4. The company has access to adequate technical and financial resources.
  5. A clear market for the end product exists.
  6. The product is demonstrated as commercially viable and technologically feasible.

For a biotech, proving this can be abstract. In practice, the interpretation is often tied to regulatory milestones. Therefore, “In biotech, the 'trigger point' for capitalisation is often considered the start of formal IND (Investigational New Drug)-enabling studies or upon acceptance of an IND application by the FDA.” This provides a clear, externally validated milestone that satisfies the stringent criteria of ASC 730.

For UK Companies (FRS 102)

The UK framework under FRS 102 is more principles-based and may allow for earlier capitalisation if specific criteria are met. Like US GAAP, it distinguishes between a 'research phase' (always expensed) and a 'development phase' (potentially capitalised). The guidance is broadly similar to international standards; compare with IAS 38 for IFRS guidance on capitalisation conditions.

Under FRS 102, development costs can be capitalised if the company can demonstrate all of the following:

  • Technical feasibility of completing the intangible asset.
  • Its intention and ability to complete the asset for use or sale.
  • How the asset will generate probable future economic benefits.
  • Availability of adequate technical and financial resources to complete development.
  • Its ability to measure the expenditure attributable to the asset reliably.

The definition of technical feasibility is not as rigidly tied to a specific regulatory event as it often is in US practice. This gives UK companies potentially more leeway to begin capitalising once a project is well-defined and on a clear path to commercialisation, even before formal regulatory submissions.

Building Your Audit-Ready Documentation for Development Costs Capitalization

Compiling and maintaining rigorous documentation is essential to substantiate capitalised R&D costs and satisfy auditors. The reality for most startups is more pragmatic: you do not need a complex ERP system. Good habits in QuickBooks or Xero are sufficient, as long as they are applied consistently.

  1. Isolate Projects: The first step is to separate general research from specific, capitalisable development projects. In QuickBooks, use the Classes feature to tag every relevant transaction (bills, salaries, expenses) to a project, like "Project Alpha - IND-Enabling Studies." In Xero, you can achieve the same with Tracking Categories. This creates a clear audit trail.
  2. Track Time Diligently: Employee salaries are often the largest R&D cost. You must be able to allocate time spent between general research and a specific development project. A simple spreadsheet is often enough to start. For each relevant employee, log the hours spent on general research versus a capitalisable project, including a brief description of the activity, such as "Exploratory assay development" (research) or "CMC scale-up for IND batch" (development).
  3. Code Invoices Correctly: When you receive an invoice from a Contract Research Organization (CRO), it needs to be coded properly in your accounting software. If a single CRO invoice covers both expensed and capitalised work, you must split it. For example, a $50,000 invoice could be recorded as two line items: $20,000 coded to the "R&D-Discovery" expense account and $30,000 coded to the "Capitalisable Development" asset account, tagged to the appropriate project class.

Remember what cannot be included in your intangible assets biotech calculation. Per the rules, “Capitalised costs that cannot be included are: General and administrative overhead, sales and marketing expenses, and routine maintenance of lab equipment.” Stick to direct costs like team salaries, contractor invoices, and specific materials consumed by the project.

The Strategic Impact: How Capitalisation Shapes Your Financial Story

Choosing to capitalise R&D is not just about compliance; it's a strategic decision that directly impacts your financial narrative and cash planning. Founders need to understand the trade-offs before committing to a path.

Improved P&L vs. Unchanged Cash Flow

First, capitalisation improves your P&L. By moving significant costs from the P&L to the Balance Sheet, you report a lower net loss or higher net income. For a pre-revenue biotech, this can make key metrics look stronger in board and investor reports. However, sophisticated investors will always look at your cash flow statement, which remains unchanged. Your cash burn is the same regardless of the accounting treatment.

Future Amortisation Expenses

Second, capitalisation introduces a future expense: amortisation. The capitalised asset does not stay on your books forever. It gets expensed over its estimated useful life once commercialisation begins. For example, an “Amortisation example: $5M in capitalised development costs with a 10-year useful life results in a $500k annual non-cash amortisation expense on the P&L during commercialisation.” This future expense will reduce your profitability once your product is generating revenue.

The R&D Tax Credit Trade-Off

Finally, there is a crucial strategic trade-off with R&D tax credits. This is where US and UK approaches diverge significantly, creating a tension between near-term cash and long-term P&L appearance.

  • In the US: The decision has a direct cash impact. “Costs that are capitalised under US accounting rules are generally not eligible for the R&D tax credit in the year they are incurred; they must be amortised for tax credit purposes.” This means you get a much smaller tax credit now, delaying the cash benefit. For a cash-constrained startup, expensing everything to maximise the immediate tax credit refund is often the preferred path.
  • In the UK: The impact on HMRC's R&D tax relief scheme is also significant. For the widely used SME scheme, the relief is calculated based on qualifying expenditures that are recorded as an expense in the P&L. Capitalising development costs removes them from this calculation, reducing the immediate cash benefit or payable credit. This creates the same tension: a better-looking P&L today versus more non-dilutive cash from tax relief.

Practical Takeaways: A Stage-Specific Action Plan

How you approach R&D capitalisation should evolve with your company's maturity. A thoughtful, phased approach ensures you are prepared for increasing complexity without over-investing in systems too early.

Pre-Seed & Seed Stage

Your focus should be 100% on diligent tracking, not capitalisation. At this stage, virtually all your activities will be considered 'research'. The most valuable thing you can do is set up your accounting system correctly from day one. Use project codes or classes in QuickBooks or Xero to track spending related to specific discovery programs, even if it is all expensed. This builds the data foundation you will need for future audits, diligence, and strategic decisions.

Series A Stage

The conversation should begin. As your lead candidate moves toward pre-clinical and IND-enabling studies, the line between research and development starts to clarify. Start modelling the financial impact of both scenarios: expensing everything versus capitalising post-feasibility. Discuss the criteria with your accountants and auditors to align on what your company’s ‘trigger point’ will be. This proactive alignment can prevent major headaches later.

Series B and Beyond

The decision becomes real and material. You likely have a well-defined development project that meets the capitalisation criteria. Now, robust documentation is mandatory. Work closely with your fractional CFO, accountants, and tax advisors to ensure your systems for time and expense tracking are audit-ready. The choice becomes a key part of your financial strategy, balancing P&L appearance with immediate cash flow from tax credits.

Conclusion

Navigating the rules of R&D capitalisation is a core financial competency for any growing biotech startup. It is not an abstract accounting theory but a practical discipline that shapes your investor narrative, tax strategy, and runway. By understanding the fundamental difference between expensing and capitalising, the specific trigger points in the US and UK, and the long-term strategic trade-offs, you can make informed decisions. The key is to start with good tracking habits today, preparing your company for the financial complexity that comes with scientific success.

Frequently Asked Questions

Q: What are the biggest risks of incorrectly capitalizing R&D costs?

A: The primary risk is a financial restatement. If auditors find that costs were capitalised too early or without sufficient evidence, they may require you to reverse the entry and expense the costs. This can damage investor confidence, trigger loan covenant violations, and be a costly, time-consuming process to correct.

Q: When should a biotech startup start talking to auditors about R&D capitalization?

A: The conversation should begin as you approach the Series A stage, well before you plan to capitalize any costs. Proactively discussing your interpretation of "technological feasibility" and your documentation process with auditors ensures alignment and reduces the risk of future disagreements or restatements. It is much easier to build the right process from the start.

Q: How do you determine the 'useful life' of a capitalized biotech asset for amortization?

A: The useful life is an estimate of the period over which the asset will generate economic benefits, typically tied to patent life or market exclusivity. For a therapeutic, this might be 10-15 years from the expected launch date. It requires significant judgment and should be determined with input from your technical and commercial teams and documented carefully.

Q: Can costs from a Contract Research Organization (CRO) be capitalized?

A: Yes, direct costs from CROs and other third-party contractors can be capitalized, provided they are directly attributable to a specific development project that meets the capitalization criteria. You must maintain detailed invoices and statements of work that clearly separate capitalisable development activities from general research or administrative tasks.
