Where the 15–25% comes from

Canadian SR&ED consulting firms typically charge a contingency fee — a percentage of the credit they help you recover. The industry range is well established:

  • 15–18% — Larger established firms (Welch LLP, BDO, MNP, RDP) for credits over $500K.
  • 18–22% — Boutique SR&ED specialist firms (most of the market) for $100K–$500K claims.
  • 22–25%+ — Smaller firms for first-time claimants under $250K, sometimes with a minimum fee floor.
  • + Audit defense — Often a separate hourly charge if CRA reviews the claim.

Why the specialist exists today

  • Interviewing your developers (4–8 hrs of their time) to reconstruct what they worked on 6–18 months ago.
  • Writing technical narratives in the language CRA expects, formatted for the T661.
  • Categorizing time and salaries against eligible projects.
  • Producing a binder of supporting evidence the accountant doesn't have time to build.

SR&ED is a tax form documenting a claim of research activity — and the specialist exists because the evidence isn't there to begin with. HammerAI doesn't file your claim. We capture R&D activity at the moment of work — git commits, JIRA tickets, source documents — and structure it into a defensible evidence package with model attribution, human approval gates, and a cryptographic seal. The evidence speaks for itself, and your accountant files the T661 with confidence.

Evidence at the source.
Filed by the accountant you already use.

HammerAI doesn't practice tax law. It produces the evidence package that lets your existing accountant practice it with confidence.

Step 1 — Capture

Developers commit. Tickets close.

HammerCLI scores every git commit. HammerRD scores every JIRA ticket. Silently, in the background — at the moment the work happens, not 12 months later.

Step 2 — Structure & Seal

HammerLedger builds the package.

Source documents go in. AI extracts findings, humans approve every claim, the entire chain — sources, decisions, model attribution — is cryptographically sealed. CRA-ready.

Step 3 — File

Your accountant files the T661.

The evidence speaks for itself. The accountant doesn't need to reconstruct or reinterpret it — they file with the supporting chain attached. If CRA reviews, the seal proves what was claimed and when.

The specialist consultant exists today because most companies can't produce defensible R&D evidence on their own. When the evidence exists, the middleman is optional.
