About the Canada Bonus Tax Calculator

What Is This Calculator?
A Canada Bonus Tax Calculator reveals why your performance bonus or commission check seems so much smaller than your regular pay. The CRA uses the "bonus method" which annualizes the payment for tax purposes, often pushing you into a higher marginal bracket temporarily. The formula is Tax on Bonus = (Tax on Annualized Income) - (Tax on Regular Annual Income).
