Bug Reports
Found a bug or wrong calculation?
Tax calculations are complex and I'm a solo developer — bugs do slip through. If a number looks wrong to you, please email me with the details below.
Please include:
- The calculator page and country / state / province you were using
- The income and settings you entered
- What figure looks incorrect and what you expected to see
Even a short note like “the Ontario effective rate seems too high at $95k” is enough to get me looking into it. I verify everything against official tax authority sources before pushing a fix.

[email protected] — copy this if you prefer a different email client.
I read every email and do my best to respond, though it may take a few days. For official tax advice, please consult a tax professional or your country's tax authority — I can only help with questions about the calculators themselves.
