Commit-by-commit AST + LLM consensus across Claude, GPT and Gemini. Every line gets a confidence score.
HMRC Additional Information Form + technical narrative + audit-trail PDF. Ready to file or hand to your accountant.
No email wall. Based on HMRC's own qualification test. Answer honestly — over-claiming is the #1 cause of enquiries.
All four HMRC tests point to a valid R&D claim. The next step is documenting the technical narrative + costs — which is exactly what MergedClaimed does from your GitHub activity.
Start your claim →You answered "no" to at least one core test. That doesn't always rule you out — the boundary can be subtle. A registered R&D adviser can scope this properly. We can introduce you to one.
Talk it through →Based on your answers this likely isn't qualifying R&D under HMRC's definition. Claiming anyway is the fast route to an enquiry. If you think the questions missed something, talk to a registered adviser first.
Ask us anywayThis is a self-assessment guide, not tax advice or a guarantee. Final eligibility rests with HMRC and your adviser.

Both plans are one-off per accounting period — no monthly billing, no auto-renewal, no contingent fees. Future accounting periods are billed separately when you come back next year.
What you don't get from us: we are software, not an HMRC-registered tax adviser. Your accountant or registered R&D adviser files the actual CT600L return using the AIF we produce.
Yes. We generate the Additional Information Form (AIF) in HMRC's required structure and back every claim line with commit/PR/ticket citations — the exact audit trail HMRC has asked for since the 2023 crackdown. The merged scheme rules (April 2024+) are baked into our rules engine.
Every claim we produce carries a SHA-256-fingerprinted AIF, a per-project audit trail of every action taken, and direct citations to the contemporaneous evidence (PRs, issues) that HMRC's GfC3 guidance specifically prefers. That evidence is generally what makes the difference under enquiry. We are not your tax adviser and cannot represent you to HMRC — your accountant or a registered R&D tax adviser handles the enquiry itself.
Advisors charge 15-25% of the credit — typically £5k-£50k per claim — for bespoke interview-driven write-ups. We are software you use yourself: we pull contemporaneous evidence from your GitHub, draft the AIF narratives from real PRs and commits, and produce an HMRC-ready PDF. Total cost £499–£999 flat. Your accountant files the actual return — that part is unchanged from working with an advisor.
Yes — for accounting periods starting on or after 1 April 2024. We handle both RDEC (20% above-the-line) and ERIS (27% for loss-making R&D-intensive SMEs). UK-only subcontractor rules and overseas-EPW restrictions are built into the rules engine.
Yes. You can export the AIF PDF and supporting CSV directly to your accountant for their CT600 submission. Year 2 we'll release an accountant-side workspace with a revenue share.
Private GitHub is fully supported (read-only OAuth, code never leaves the EU, stored encrypted). GitLab and Bitbucket support is on the roadmap for Month 3. Self-hosted? We have an air-gapped scanner for enterprise customers.
