Who can claim outsourced R&D? Follow the contract, rights and research risk.

A company hires an engineering studio to solve a difficult technical problem. The studio experiments, delivers working software and sends an invoice. Which business can include the work in its federal research-credit calculation?

The invoice cannot answer that. Start with two different perspectives: the customer paying for research and the contractor performing it. Their rights, obligations and expense populations need separate analysis. A contract heading such as “fixed price” or “R&D services” is a starting point for questions, not a conclusion.

This guide concerns ordinary outsourced engineering arrangements under U.S. federal rules, researched October 7, 2026. The examples are fictional; actual contract interpretation and tax treatment require a review of the full facts.

The customer: paying for research or buying a result?

For the customer's contract-research expense, the governing regulation requires an agreement made before the work, research performed on the customer's behalf and an obligation to bear the expense even if the research fails. A right to the results can be nonexclusive. A success-contingent payment is treated as buying the result rather than paying for research performance; a mixed payment requires separating that contingent portion. Treasury Regulation 1.41-2(e)(2)–(3).

Read the master agreement together with statements of work, acceptance criteria, amendments and termination provisions. Ask what the customer actually owes if an attempted approach does not work. Distinguish an obligation to conduct specified work from an obligation to deliver a successful result. Escalate ambiguous clauses rather than inferring their meaning from the payment schedule.

Even a qualifying arrangement does not turn its whole invoice into qualified research expenses, or QREs. The IRS examination guide explains that mixed services require identifying the attributable qualified portion; an hourly service arrangement requires reviewing the actual work. That guide is examination guidance, not a substitute for the governing law. IRS qualified-research-expense examination guide.

The contractor: was its research funded?

The performer has a different question. Research is excluded to the extent another party funds it. Current regulation expressly incorporates the funding rules in Section 1.41-4A(d), despite that section's historical title. Treasury Regulation 1.41-4(c)(9).

Those rules consider all relevant agreements. Success-contingent payments are not funding under this test. However, a performer retaining no substantial rights has fully funded research; general experience gained is insufficient. If payment depends on success and the performer retains no substantial rights, the rules can exclude both parties. Retained rights also do not erase funding from noncontingent payments. Treasury Regulation 1.41-4A(d).

Avoid reducing this review to “who owns the repository?” The commercial agreement may distinguish reusable methods, customer-specific deliverables, licensing rights and background intellectual property. Put the relevant clauses beside the work description and obtain a considered interpretation.

A fictional contrast: the same technical work, different obligations

Imagine Northbank commissions a retrieval-performance experiment from Cedar Engineering. Both are operating businesses; all work occurs in California. For this illustration, assume an adviser has separately established that the selected activities meet the research tests.

This contrast illustrates the regulatory distinction above. It does not mean every fixed-price contract matches the second row. A price cap, warranty or acceptance clause needs interpretation in the complete arrangement.

Suppose the first engagement costs $120,000. The fictional workpaper supports $90,000 of qualified services and excludes $30,000 of routine deployment work. Applying the ordinary 65% inclusion yields $58,500 of contract-research QREs, not a $58,500 credit or refund. The Form 6765 instructions state that ordinary percentage and identify special research categories with different percentages. The eventual credit needs its own calculation. IRS Form 6765 instructions, line 45.

Build the evidence around decisions

Use one review record for each material arrangement. Our suggested structure pairs commercial facts with technical and financial support:

Also establish where the work occurred. A U.S. vendor address does not establish every engineer's work location. The credit rules apportion cross-border contract research and exclude the portion performed outside the United States, Puerto Rico and U.S. possessions. Treasury Regulation 1.41-4(c)(7).

Record excluded and unresolved amounts alongside proposed amounts. Preserve the agreement version used for each period; a later amendment should not silently replace the evidence of earlier obligations.

Keep AI invoices and deductions in their own analysis

A cloud or model-provider invoice does not establish that the provider performed qualified research for the customer. Computer-use expenses have a separate regulatory route with conditions; classify the actual service before assigning a percentage. Treasury Regulation 1.41-2(b)(4).

Section 174A permits deductions for domestic research or experimental spending in tax years beginning after December 31, 2024. That deduction does not dispense with the credit's additional tests. Keep deduction treatment, QRE inclusion and commercial ROI as separate workpaper conclusions. IRS Form 6765 instructions.

AI can help locate conflicting clauses or draft questions, but a reviewer should verify every interpretation against the agreement. Never let a summary invent rights absent from the contract.

Proforma's initial evidence review can organize supplied agreements, project records and cost evidence into supported notes and visible gaps. Preparation can be manual. Use the first engagement to clarify the decisions and missing records; eligibility, contract interpretation and filing remain matters for the responsible advisers.
