The most useful message you can send us is a correction.
Send us a message
Corrections are the most useful thing you can send. Tell us the calculator, what it returned, and what you expected — a link to the authority that publishes the right figure turns a report into a fix.
Reporting an error
If a number looks wrong, tell us which calculator, what it returned and what you expected. A link to the authority that publishes the correct figure turns a report into a fix, usually within the same week.
Corrections are verified against the source before anything changes, and the last-verified date on the tool is updated when they are.
Suggesting a calculator
There is a long list of tools waiting to be built, and requests move things up it. The useful details are what you were trying to work out, what you searched for, and what the existing tools got wrong or would not tell you.
We cannot build everything. Anything that needs live market data, a paid data feed or a professional judgement call is out of scope by design — those are the tools that quietly go stale.
What we cannot help with
We cannot answer questions about your own tax, benefit, immigration or academic situation. Those need the body that administers the programme, or a qualified professional.
The sources listed at the bottom of every calculator are the fastest route to the right one — they link directly to the CRA, Service Canada, the provincial ministry or the university registrar that sets the rule in question.
