Best SR&ED Software for Canadian Startups (2026)

"Best SR&ED software" is not about flashy dashboards — it is about whether you can produce a defensible T661, accurate financial schedules, and audit-ready documentation without rebuilding everything in Excel every April.

Our SR&ED software comparison guide lists evaluation criteria; here is what matters in practice.

1. Eligibility screening before you invest

Good platforms screen projects against CRA's framework before you spend weeks on data entry. A readiness score against the five-question test saves founders from filing weak claims.

2. Document intelligence

Invoices, payroll, and contractor records should flow into categorized expenditures — salaries, materials, subcontractors — with human review before import. Manual re-keying is where errors and audit flags start.

3. T661 narrative structure

Lines 242, 244, and 246 have specific purposes. Software should guide you through technological objectives, uncertainties, and systematic investigation — not produce generic marketing copy.

See writing the technological narrative for what strong content looks like.

4. Financial engine depth

Minimum capabilities:

• Proxy vs traditional method toggle with live ITC estimates
• Contractor 80% rule and unpaid salary rules
• Grant offsets and government assistance
• Provincial grind-down awareness (federal vs provincial)

5. Export and accountant handoff

CRA-ready PDF schedules (T661, provincial forms where applicable) should export without a week of reformatting. Your accountant should receive consistent numbers, not a second parallel model.

6. Path to expert review

Software-only works for many first claims. The best tools let you add engineering-led expert review when complexity or refund size warrants it — without switching systems mid-year.

Province and industry context

• SR&ED by province — Ontario, Quebec, BC, and all Canadian jurisdictions
• SR&ED by industry — software, manufacturing, biotech, and more

Bottom line

The best SR&ED software combines accurate math, structured narratives, and optional expert backup. Evaluate tools on audit outcomes and time saved — not feature count alone.
