Canadian Self-Employed Tax Calculator
Work out income tax and CPP on your profit as a self-employed person, and how much to set aside.
Quebec self-employed (QPP, QPIP) is not included yet.
Self-employed people pay both the employee and employer CPP (11.9%, plus 8% CPP2). The employer half is deductible. EI is optional and not included. Enter profit after business expenses.
Your take-home pay · per month
$51,912 a year from $70,000 gross, you keep 74.2%
You pay both halves of CPP
Self-employed people pay the employee and employer portions of CPP: 11.9% on profit between $3,500 and $74,600, plus 8% CPP2 up to $85,000.
What is deductible
The employer half of CPP, the enhanced portion of the employee half and all of CPP2 are tax deductions. The base employee portion earns a credit.
No EI by default
Self-employed people can opt in to EI special benefits but do not pay EI premiums by default, so none are included here.
