How to pay an independent contractor in Canada (Without triggering a CRA audit)

Paying an independent contractor feels simple. Agree on a rate, do the work, send payment. Done.

Except it’s not. In Canada, how you pay contractors, what you document, how you classify the working relationship and whether you’re issuing the right tax slips all sit firmly in the CRA’s line of sight. Get it wrong and you’re not just looking at an awkward conversation. You’re looking at reassessments, penalties and back-payments that can stretch years into the past.

This guide cuts through the noise so you can pay contractors confidently and cleanly.

Why contractor payments carry real audit risk

The CRA doesn’t take your word for it when you say someone’s a contractor.

They look at the actual working relationship. How much control do you have over how the work gets done? Does the worker operate their own business? Are they financially at risk? Do they work for other clients?

If the facts don’t line up with the “independent contractor” label, the CRA can reclassify the worker as an employee. When that happens, you’re on the hook for the CPP contributions, EI premiums and income tax that should have been withheld from day one, plus interest and penalties on top.

And it’s not a hypothetical risk. Misclassification is one of the most common payroll compliance issues the CRA investigates, particularly in industries where project-based and flexible work is common.

Beyond classification, there are other tripping points:

• Not issuing T4A slips when you’re required to
• Paying without collecting proper invoices or business numbers
• Handling GST/HST incorrectly (or not at all)
• Weak payment records that can’t survive an audit

Most of these mistakes are entirely avoidable. That’s exactly what this guide is for.

What’s inside the guide

We built this resource for Canadian employers, founders, finance leads and HR operators who are working with contractors and want to get the process right from the start.

Inside, you’ll find:

• The CRA’s worker classification test explained in plain language—what factors the CRA uses, what signals indicate an employee vs. a contractor and how to document the distinction clearly
• When and how to collect invoices—what a proper contractor invoice needs to include and why a paper trail matters more than you think
• GST/HST explained for payer businesses—when contractors need to charge GST/HST, when you need to collect it and how to handle payments correctly
• T4A obligations—when you’re required to issue a T4A, what to report in Box 048 and Box 020 and the $500 threshold rule
• Payment record-keeping best practices—what to keep, how long to keep it and what the CRA expects to see if they come knocking
• Red flags that attract CRA scrutiny—the common patterns that move your business up the audit priority list and how to avoid them
• A practical contractor payment checklist—a step-by-step framework you can use every time you bring a new contractor on
