Why we built this
Most Canadian calculators online either come from banks that route you into a sales funnel, or they reuse US tax logic that misses CPP2, the federal Basic Personal Amount phase-out, Quebec's separate income tax, and the indexation factors the CRA updates each January and July.
We build tools that handle these correctly, cite every source, and show the date each value was last checked. Read the methodology for how we build, test, and maintain each calculator.
