Why we publish these
Most Canadian tax questions are not really arithmetic questions. Someone searching "how much tax will I pay on a raise" usually wants to know why the answer is not simply their tax bracket. Someone comparing an RRSP to a TFSA usually wants to know which one their own situation actually favours. A calculator can only give you the output; these guides give you the reasoning, so you can judge whether the output applies to you.
Everything here is written for the 2026 tax year and checked against the body that sets each figure — the Canada Revenue Agency, Revenu Québec, or the relevant provincial budget. Where a rule is genuinely uncertain or commonly misreported, we say so rather than picking a confident-sounding answer. Our full approach is on the methodology page.
