R&D tax credit documentation and engineering project analysis

Your R&D Investment
Documented for the Credit

Technology companies spend real money on qualifying research and development — and the IRC §41 credit exists precisely for that. Synthfin works with your engineering and product teams to identify qualifying activities, calculate creditable expenditures, and build the contemporaneous documentation that supports the credit on your return.

What this engagement delivers

The R&D tax credit is one of the more valuable credits available to technology companies — and also one of the more documentation-intensive. The IRS expects contemporaneous records, a clear four-part test analysis for each qualifying activity, and a credible calculation of qualified research expenditures. When that documentation isn't in place, the credit becomes difficult to defend on examination.

When this engagement is complete, you have a credit supported by a complete documentation package — one that holds up under review and gives your tax preparer a clear basis for the claim.

Qualifying projects and activities identified through structured interviews with your technical team

Four-part test analysis documented for each activity claimed

Qualified research expenditures calculated from wages, contractor costs, and supply expenses

Contemporaneous documentation package prepared and organized for your tax return and any future examination

// identified.challenge

Where R&D credit claims run into difficulty

problem_01

Activities identified too broadly

Not every development activity qualifies. Routine bug fixes, post-release maintenance, and work that doesn't involve technological uncertainty generally don't meet the four-part test. Overclaiming without documentation creates examination exposure that can exceed the value of the credit itself.

problem_02

Documentation assembled after the fact

The IRS expects contemporaneous records — documentation created at or near the time the qualifying work was performed. Records assembled months later in response to a tax filing, or years later in response to an audit, carry less weight and are harder to defend.

problem_03

QRE calculation gaps

The qualified research expenditure calculation requires allocating wages, contractor costs, and supply expenses to qualifying vs. non-qualifying activities. Without a consistent methodology for this allocation, the credit number is difficult to support on examination — even when the underlying activities genuinely qualify.

// our.approach

How we handle it

activity_identification

Structured technical interviews

We work directly with your engineering and product teams to identify qualifying projects and activities. These interviews are structured around the four-part test — technological in nature, elimination of uncertainty, process of experimentation, qualified purpose — so the output maps directly to the credit requirements.

qre_calculation

QRE calculation and allocation

We calculate qualified research expenditures from your payroll data, contractor agreements, and supply records — applying a consistent allocation methodology that separates qualifying from non-qualifying time and costs. The calculation is documented at the activity and employee level.

documentation_package

Contemporaneous documentation

The documentation package we prepare includes project-level descriptions, four-part test analysis for each activity, employee interview summaries, time allocation support, and the QRE calculation workbook. This is organized for your tax preparer and structured to respond to examination requests without additional reconstruction.

tax_coordination

Coordination with your tax preparer

We hand off the completed documentation package to your CPA or tax preparer with a summary memo explaining the credit calculation and methodology. We're available to answer their questions and to provide additional support if the return or credit is examined.

// what.to.expect

How the engagement runs

phase_01

Scoping

We review your product roadmap, project history, and org structure to identify which teams and projects are candidates for the credit. This shapes the interview schedule and the scope of QRE documentation.

phase_02

Technical interviews

We conduct structured interviews with engineers, product managers, and technical leads. Sessions are focused, usually thirty to sixty minutes per person, and coordinated around your team's schedules to minimize disruption.

phase_03

Calculation and documentation

We build the QRE calculation from your payroll and contractor data, apply the allocation methodology, and prepare the full documentation package. Drafts are reviewed with your team before finalization.

phase_04

Delivery and handoff

The completed package — QRE workbook, project descriptions, interview summaries, and methodology memo — is delivered to you and your tax preparer with a walkthrough call to address any questions before filing.

Get Started

// pricing.note

The fixed fee covers a standard engagement. Companies with a high volume of qualifying projects, multiple legal entities, or complex contractor arrangements may require additional scope, which we'll identify and agree on upfront. We don't adjust the fee after work has begun without a written change in scope.

// designed.for

This service fits well if you are a

— Technology company investing in product development, process improvement, or experimentation

— Business that has been claiming the credit without formal documentation behind it

— Company approaching the credit for the first time and wanting a clean starting point

— Team whose existing credit study needs to be rebuilt or updated

// methodology.framework

The standard we work to

IRC §41 — Four-Part Test

01

Technological in nature

The activity must fundamentally rely on principles of physical, biological, computer, or engineering science

02

Elimination of uncertainty

The activity must be intended to discover information to eliminate technical uncertainty about capability or method

03

Process of experimentation

The activity must involve evaluation of alternatives through modeling, simulation, systematic trial, or similar processes

04

Qualified purpose

The activity must be for a new or improved business component — function, performance, reliability, or quality

// recent.work

April 2026

Delivered an IRC §41 documentation package covering three qualifying development projects for a product-led growth company, including full four-part test analysis and QRE calculation from payroll and contractor records.

March 2026

Completed a credit study for a developer tooling company claiming the credit for the first time — interviews with six engineers, documentation of nine qualifying projects, and a methodology memo prepared for their external CPA.

// typical.timeline

Most engagements run four to six weeks from kickoff to final delivery, depending on the number of technical interviews required and the availability of payroll and contractor data. We work around your team's schedules.

// our.commitment

How we approach the relationship

conservative_claims

We document what qualifies — not everything possible

Our goal is a defensible credit, not the largest possible number. If an activity doesn't clearly meet the four-part test, we'll tell you — and explain why — rather than stretch the claim and create examination exposure.

examiner_ready

The package is built for examination

Everything we prepare is organized as if an examiner might request it. That means no gaps in the documentation trail, no conclusions without support, and no numbers that can't be traced back to source records.

initial_conversation

Start with a conversation

If you're not sure whether your activities qualify or whether the credit makes sense for your situation, reach out. We can give you a read on your activities before you commit to an engagement — no obligation attached to that conversation.

// next.steps

Getting started is straightforward

step_01

Send a message

Describe your development activities, your team size, and the tax year you're looking to document. That context helps us give you a useful response quickly.

step_02

Qualification review

We'll have a call to assess your activities against the four-part test criteria and give you an honest view of what's likely to qualify before any engagement begins.

step_03

Written scope and kickoff

We'll send a written scope confirming the fee, deliverables, and interview schedule. Once agreed, we coordinate directly with your technical team to get started.

// take.action

Your development work may already qualify. Let's find out.

If your engineering team is building new features, improving performance, or working through technical problems without a clear solution in sight, the credit is worth a closer look. Reach out and we'll help you figure out whether it applies.
