Questions Frequentes
Do contractors pay CPP in Canada?
Yes. Self-employed individuals pay both the employee and employer portions of CPP, totalling 11.90% on pensionable earnings between $3,500 and $71,300.
Do self-employed contractors pay EI?
EI is not mandatory for self-employed individuals. You can opt in through Service Canada to access maternity, parental, sickness, and compassionate care benefits.
When must I register for GST/HST?
Registration is mandatory once your revenue exceeds $30,000 in four consecutive calendar quarters. Below that threshold, GST/HST registration is voluntary.
What expenses can contractors deduct?
Common deductions include home office costs, vehicle expenses, professional fees, software, supplies, and a portion of phone and internet bills. Keep all receipts for CRA.
Is it better to incorporate or stay self-employed?
Incorporating can offer tax advantages above approximately $100,000 net income through the small business deduction (9% federal rate). Below that, the administrative costs of incorporation often outweigh the benefits.
How do I pay quarterly tax installments as a contractor?
If you owe more than $3,000 in net tax for the year, CRA requires quarterly installment payments (March 15, June 15, September 15, December 15). Failing to pay installments on time results in interest charges.
