How Our Content Is Researched and Written
Last reviewed:
How TaxKiln Canada's editorial content is researched, written, and maintained. Every guide is built from primary statute and CRA publications, cross-referenced through structured research synthesis, and reviewed on a defined cycle. Every factual claim in our guides is traceable to a primary source.
Research methodology
**Primary sources first.** Every TaxKiln Canada guide is anchored in primary authority: - The Income Tax Act (ITA). - The Excise Tax Act (ETA). - Canada Pension Plan legislation. - CRA publications including the T4002 (Self-employed Business, Professional, Commission, Farming, and Fishing Income guide), Interpretation Bulletins, Technical Interpretations, Income Tax Folios, and GST/HST Memoranda. - Provincial tax legislation for the 13 provinces and territories. **Secondary sources for cross-reference.** CPA Canada publications, Canadian Tax Foundation research papers and conference reports, and Tax Court of Canada decisions. **Structured research synthesis.** We use structured research synthesis to cross-reference multiple authoritative sources before publishing any guide. Every factual claim in our guides is traceable to a primary source, and every rate, threshold, and statutory citation is verified against at least two independent references before publication.
Review cycle
- All guides carry a 'Last reviewed' date visible on the page. - Tax rate pages are updated when CRA publishes new indexed amounts — typically January each year for the upcoming tax year. - Budget-impacted pages are updated within 30 days of the Federal Budget or the relevant provincial budget. - Trade guides are reviewed annually against provincial licensing changes and trade-specific regulatory updates. - Pages affected by significant Tax Court of Canada decisions are reviewed when those decisions are released.
Canadian professional authorities referenced
- CPA (Chartered Professional Accountant) — the unified Canadian designation, replacing the legacy CA, CMA, and CGA designations after unification. - Provincial CPA bodies including CPA Ontario, CPA British Columbia, CPA Alberta, and the Ordre des CPA du Québec. - The Canadian Tax Foundation, the country's leading independent tax research organisation. - The Tax Court of Canada (TCC), whose decisions are the authoritative interpretation of contested ITA and ETA provisions. Where we signpost professional advice, we direct readers to the relevant provincial CPA body's directory rather than naming specific firms.
Editorial review and corrections
Every page is editorially reviewed for statute accuracy, interaction coverage, and edge-case completeness before publication. If you find content that is inconsistent with current statute or current CRA guidance, please email hello@kilnguides.co.uk.
