Understanding R&D Capitalization for Tech and Startup Founders

R&D capitalization is the process of recording research and development costs as a long-term asset instead of expensing them immediately. Under post-2022 IRS rules, all R&D costs must be capitalized and amortized over five years for U.S. development and fifteen years for foreign development.

R&D accounting rules changed in 2022, and they now affect your runway, burn rate, and tax bill in ways most founders don’t expect. If you build software, ship fast, or run a product‑heavy roadmap, you need to understand how R&D capitalization works and when it makes sense to use it.

This guide breaks down the rules without jargon. You’ll see how capitalization affects your financials, how amortization works, and when founders should (and shouldn’t) capitalize costs.

What Is R&D Capitalization?

R&D capitalization means recording research and development expenses as an asset instead of taking a full expense on your P&L today. For startups investing heavily in product, this changes how profit, EBITDA, and investor-facing metrics appear.

When you capitalize R&D:

• The cost goes on your balance sheet.

• You amortize it over several years.

• Your P&L shows higher near-term profitability.

• Investor metrics become smoother and more comparable over time.

When you expense R&D:

• You deduct everything immediately.

• Profit drops in the current year.

• Metrics look more volatile.

For software companies, this choice affects everything from burn-rate reporting to fundraising decks.

Why Capitalize R&D?

Capitalizing development costs spreads the expense over time. Instead of taking the full hit today, you amortize the cost across future years—the same years the product generates revenue. 

For early-stage teams, capitalized R&D can:

• Reduce volatility in EBITDA

• Present cleaner, more consistent margins

• Reflect the long-term value of product investment

• Improve comparability across reporting periods

This is why many tech companies adopt a capitalization strategy once engineering spend grows.

How R&D Capitalization Works for U.S. Tax Purposes (Post-2021 Rules)

In 2022, tax treatment changed across the board. Regardless of GAAP or IFRS, the IRS now requires all R&D costs—U.S. and foreign—to be capitalized for tax purposes.

This applies to:

• Software development

• Engineering work

• Product iteration

• Testing and QA

• Domestic and international R&D efforts

Even if you want to expense the work for bookkeeping, tax rules force capitalization.

Five-Year vs. Fifteen-Year Amortization

The IRS requires different amortization schedules depending on where the work is done:

• U.S.-based R&D: amortized over five years

• Foreign R&D: amortized over 15 years

This creates a major cash-flow impact. Instead of deducting 100% in year one, you deduct only a fraction.

The result: phantom income

You can owe taxes even while operating at a loss because the deduction is spread over future years. This surprises many founders during their first post-2022 tax season.

Capitalized vs. Non‑Capitalized Costs

Capitalizable:

• Software development after feasibility

• Engineering work tied to a specific product build

• Patent application costs

Expensed:

• Early research

• Market testing

• Surveys

• General admin or overhead

What Might Change in 2025?

Legislators have proposed restoring full expensing for U.S.-based R&D through 2025.

Nothing is final yet, so model both outcomes until guidance is official.

GAAP vs. IFRS Treatment of R&D (Side-by-Side Comparison)

Founders often assume all accounting frameworks treat R&D the same way. They don’t. GAAP is strict. IFRS is flexible. Startups with global operations or international subsidiaries may report very different metrics depending on the framework.

R&D Accounting: GAAP vs. IFRS

Why GAAP Is Stricter

GAAP wants to avoid overstating a startup’s assets. Under U.S. rules, you must prove software is “technologically feasible” before capitalizing development costs — and in fast-moving environments, feasibility can last only a few days or weeks.

That’s why most U.S. startups default to expensing nearly everything.

Why IFRS Is More Flexible

IFRS focuses on whether:

• the product will generate future economic benefits

• the team can reliably measure development spend

• the technology is feasible

If those conditions are met, IFRS allows capitalization far earlier than GAAP. This can materially change profitability, EBITDA, and valuation optics.

How R&D Capitalization Works

Capitalization affects both tax strategy and budgeting. You spend the same cash, but the tax deduction spreads out.

Real‑World Example

A startup with $1M revenue and $1.5M R&D spend:

• Old rules: full $1.5M deduction → no tax owed

• New rules: only $300K deduction (one‑fifth) → $147K tax bill despite a $500K economic loss

Budget and Runway Impact

Capitalization changes how your burn rate appears on paper and can shorten runway if you’re not modeling amortization correctly.

Benefits for Startups & Tech Companies

More Accurate Profitability

Capitalizing R&D aligns spend with future revenue, reducing noise in investor‑facing metrics.

Higher EBITDA and Cleaner Ratios

Shifting early R&D off the income statement boosts:

• Net income

• EBITDA

• ROA and ROE

Smoother Cash Flow Planning

Amortization helps founders forecast margins and model long‑term ROI more accurately.

GAAP Requirements for Software R&D

Internal‑Use Software (ASC 350)

• Planning stage: Expense

• Development stage: Capitalize qualifying costs

• Post‑implementation: Expense again

External (Marketed) Software (ASC 985)

• Planning: Expense

• After technological feasibility: Capitalize

• Post‑release: Expense

Capitalization windows for startups are short. If you ship fast, feasibility‑to‑release may be only a few weeks.

Should You Capitalize R&D Costs?

Capitalize when:

• The project is large, structured, and easy to track

• You want cleaner EBITDA or investor optics

• You have a clear feasibility window

Expense everything when:

• Tracking costs adds operational friction

• The development cycle is rapid

• The amortization benefit isn’t worth the bookkeeping overhead
