Understanding Subcontractor Tax Rules in Canada

In Canada, understanding the tax obligations associated with subcontracting is crucial for both contractors and subcontractors to ensure compliance with the Canada Revenue Agency (CRA) regulations. This guide provides an overview of the key tax considerations for subcontractors operating within Canada.


1. Determining Employment Status

The first step in understanding tax obligations is to determine whether a worker is an employee or a self-employed subcontractor. This classification affects tax responsibilities, including income tax, Canada Pension Plan (CPP) contributions, and Employment Insurance (EI) premiums. The CRA evaluates several factors to make this determination:


  • Control: The degree of control the payer has over the worker's activities.

  • Ownership of Tools: Who provides the tools and equipment.

  • Chance of Profit/Risk of Loss: The worker's opportunity for profit and risk of loss.

  • Integration: The extent to which the worker is integrated into the payer's business.


For detailed guidance, refer to the CRA's publication on Employee or Self-employed.


2. Reporting Payments to Subcontractors

Contractors in the construction industry are required to report payments made to subcontractors using the T5018 slip, known as the "Statement of Contract Payments." This requirement applies if:


  • More than 50% of the business income is derived from construction activities.

  • Payments were made to Canadian resident subcontractors for construction services performed inside or outside Canada.

  • Total payments to a subcontractor in the calendar year exceed $500, excluding GST/HST.


The T5018 slip must include the total amount paid to each subcontractor, including GST/HST and PST where applicable. For more information, consult the CRA's guide on T5018 slip – Statement of contract payments.


3. Subcontractor's Tax Responsibilities

Subcontractors classified as self-employed are responsible for:

  • Income Tax: Reporting all business income and expenses on their personal income tax return.

  • CPP Contributions: Paying both the employer and employee portions of CPP contributions.

  • GST/HST: Registering for GST/HST if annual taxable supplies exceed $30,000 and remitting the collected tax to the CRA.

For comprehensive information, refer to the CRA's resources on Small businesses and self-employed income.


4. Withholding Tax for Non-Resident Subcontractors

When payments are made to non-resident subcontractors for services performed in Canada, the payer is generally required to withhold a 15% tax on the payment. This withholding is mandatory unless the subcontractor obtains a waiver from the CRA. Details are available in the General Conditions of a Service Contract.


5. Record Keeping

Both contractors and subcontractors must maintain detailed records of all transactions, including contracts, invoices, and proof of payments. Proper record-keeping is essential for accurate tax reporting and compliance with CRA requirements.


6. Tax Rules for Freelancers

Freelancers in Canada, much like subcontractors, are considered self-employed individuals under the CRA's guidelines. This means they have specific tax obligations, including:


  • Income Reporting: Freelancers must report all income earned from clients on their personal tax return. This includes payments for services, royalties, and any other business income.

  • Business Expenses: Freelancers can deduct eligible business expenses such as home office costs, software, travel, and professional development. Ensure these expenses are directly related to income generation and keep detailed records.

  • GST/HST Obligations: Freelancers are required to register for and collect GST/HST if their annual taxable revenues exceed $30,000. They must remit the collected tax to the CRA and file regular GST/HST returns.

  • CPP Contributions: As self-employed individuals, freelancers are responsible for both the employer and employee portions of CPP contributions.

  • T2125 Form: Freelancers must complete Form T2125 (Statement of Business or Professional Activities) as part of their tax return to report business income and expenses.


The CRA provides detailed guidance on tax obligations for the self-employed. Proper financial planning and record-keeping are essential for freelancers to meet their tax responsibilities and avoid penalties.
