*This calculator estimates the non-refundable tax credit for eligible donations based on your province or territory of residence and donation amount. It does not account for all tax situations, including higher rates for top income brackets or recent tax changes. Since calculations depend on the accuracy of your entries, please ensure they are correct. As a non-refundable credit, it reduces tax owed but does not result in a refund if no tax is due. Additional restrictions may apply based on income and provincial considerations.
