Get in Touch
We welcome feedback on the calculator — especially if you believe a rate or threshold needs correction, or if you've found a scenario that produces an unexpected result.
You can reach us at: hello@marginaltaxcalc.ca
Rate Corrections
If you believe a bracket, threshold, or rate is incorrect, please cite the official CRA or ESDC source publication so we can verify and update promptly. We take accuracy seriously and aim to correct verified rate errors within 24 hours of notification.
What We Can't Help With
We are not tax professionals and cannot provide individual tax advice. For personal tax planning — RRSP strategy, income splitting, capital gains optimization, business income structuring, or audit support — please consult a Chartered Professional Accountant (CPA) licensed in Ontario.
