Filing your return and expecting a refund, only to receive a Notice of Assessment showing the money was applied to an old debt instead, is a common and frustrating surprise. This is usually the result of set-off — the CRA's authority to apply a refund or certain benefit payments against an outstanding debt instead of sending you the money.
Set-off isn't limited to the CRA's own tax debts. In some cases, it can be used to collect other amounts owed to the federal or provincial government, depending on the program involved. Understanding how it works helps you figure out whether what happened was routine or worth pushing back on.
This article explains what set-off means, what it commonly applies to, and what to do if you think it was applied in error.
What "Set-Off" Actually Means
Rather than paying out a refund and then separately trying to collect an outstanding debt, the CRA can apply the refund against the debt first and pay out only the difference, if any. The same idea can apply to certain government benefit payments, not just tax refunds. From the government's perspective, this avoids paying money out with one hand while trying to collect it back with the other.
What Can Be Applied This Way
| Type of debt | General likelihood of set-off |
|---|---|
| Outstanding personal income tax balance | Commonly applied against a current-year refund |
| Outstanding corporate tax or GST/HST balance | Commonly applied against related refunds or credits |
| Other federal government debts, such as certain benefit overpayments or student loan debts | Can be applied, depending on the specific program and its rules |
| Some provincially administered benefits | Treatment varies by program — don't assume set-off automatically applies or automatically doesn't |
Some benefit payments receive more protection from set-off than others under the rules governing that specific program. Because this varies and changes, don't assume a particular benefit is either fully protected or fully exposed without checking the current rules for that program.
How Set-Off Compares to Other CRA Collection Tools
Set-off is generally a lighter-touch tool than the more aggressive collection mechanisms the CRA can use once a debt has escalated — a Requirement to Pay sent to your bank or employer, or a lien registered against real property. Set-off only intercepts money the government already owes you through a refund or benefit; it doesn't reach into an account or property you already hold. That said, it can still be the first sign that a larger collection problem exists, and it's worth treating it as a prompt to check the full picture of what you owe rather than as a one-off inconvenience.
Notice and Explanation
When a refund is applied against a debt, the resulting Notice of Assessment, or a separate CRA notice, will generally show the set-off: the refund amount you expected, the amount applied, and what's left, if anything. If you weren't previously aware you had an outstanding balance, this can be the first real notice you get of it, which understandably catches people off guard.
What to Do If You Think It Was Applied in Error
- Read the notice carefully. Confirm exactly which debt the CRA says the refund was applied against, and the amount.
- Check your CRA online account for the underlying balance the set-off relates to, if you have access.
- Call the CRA to ask for the specific basis for the set-off if it isn't clear from the notice.
- If you dispute the underlying debt, not just the fact that a refund was applied to it, pursue that through a Notice of Objection if it relates to an assessment you disagree with.
- Get legal advice if a set-off was applied to a debt you believe is wrong, already paid, or someone else's.
Frequently asked questions
Can the CRA apply my refund to a debt I'm actively disputing?
It depends on the type of debt and where the dispute stands. Some disputes limit standard collection action on the disputed amount, but the rules differ for individuals, corporations, and GST/HST debts — confirm the specific treatment for your situation rather than assuming either way.
Can my spouse's tax debt be taken from my refund?
Generally, set-off applies to debts owed by the person whose refund it is, not automatically to a spouse's separate debt, but joint filings, joint benefit calculations, and shared accounts can create situations worth checking carefully with a tax professional.
If the CRA takes my refund, does that mean the debt is fully paid?
Only if the amount applied covers the full balance, including any accrued interest. A partial set-off reduces the debt but doesn't necessarily eliminate it.
Can I stop future refunds from being applied to an old debt?
Not generally, if the debt remains outstanding. The more direct path is to resolve the underlying debt itself, whether by payment, a payment arrangement, or successfully disputing it.
Does set-off apply to a business's corporate tax refund the same way it applies to an individual's?
The same basic idea applies — an outstanding balance can be applied against a refund the corporation would otherwise receive — but which debts and which refunds get matched up can involve more moving pieces for a business with multiple accounts and filings. Confirm the specifics with the CRA or a tax professional rather than assuming it mirrors the personal-tax situation exactly.
