Every source we cite

103 distinct sources cited across 35 of Countworthy’s 36 calculators.

How we choose sources

We use the publisher, not a summary of the publisher — Canadian tax figures come from the Canada Revenue Agency's own payroll formulas and the provincial tables, not from an article about them. Every figure is traced to the primary source that publishes it, and the page records the date somebody last read that source: that date is what "Formula last verified" means on every calculator. Where a source could not be reached directly, the calculator's own audit trail says so rather than quietly citing something weaker.

This page lists citations, not endorsements — a source appearing here is the reference a figure was checked against, nothing more. See how we verify every number for the full system this list is one part of.
