The Tax Debt That Never Dies: Why Parliament Must Reform Section 160

Canada needs a principled limit on transferee liability without giving tax debtors a road map for avoiding collection

By Amit Ummat, Principal Counsel, Ummat Tax Law PC

A Collection Rule Without an Expiry Date

Most tax disputes begin with the taxpayer whose income, deductions or transactions are under review. Section 160 of the Income Tax Act is different. It permits the Canada Revenue Agency to collect one person’s tax debt from someone else. In broad terms, if a taxpayer transfers property to a spouse, a minor or another person with whom the taxpayer was not dealing at arm’s length for less than fair market value, the recipient may become jointly and severally liable for the transferor’s tax debt. The recipient’s liability is generally capped at the lesser of the transferor’s relevant tax debt and the value transferred in excess of the consideration paid.

The policy is understandable. A taxpayer should not be able to defeat collection by giving assets to a family member and leaving the CRA with an empty shell. The difficulty lies not in the existence of section 160, but in its design. Subsection 160(2) provides that the Minister may assess a transferee “at any time.” There is no ordinary reassessment period. There is no requirement that the transferee knew about the transferor’s tax debt. There is no general due diligence defence. There is no requirement that tax avoidance motivated the transfer. The provision can therefore operate decades after an ordinary family transaction against a recipient who neither intended nor understood that a tax debt was being placed beyond the Crown’s reach.

That is an extraordinary form of liability. It is also increasingly difficult to justify in a tax system that otherwise treats limitation periods, documentary retention rules and certainty as essential features of fair administration.

The Problem Is Not the Anti-Avoidance Purpose

Section 160 serves a legitimate and necessary collection function. The Federal Court of Appeal explained in Canada v. Livingston, 2008 FCA 89, that its purpose is to preserve the value of a tax debtor’s assets for collection. If property is transferred for full fair market value, the Crown has not been prejudiced because equivalent value remains with the debtor. If property is given away, the provision allows the Crown to pursue the value that has left the debtor’s estate.

The statutory conditions are mechanical. They focus on the existence of a transfer, the relationship between the parties, the transferor’s tax liability and the difference between the property’s fair market value and the consideration given. Once those conditions are established, good faith generally does not answer the assessment. A spouse who received funds to pay household expenses, an adult child who received assistance with a home purchase or a family member whose name was added to an account may face a derivative assessment long after the transaction. Whether liability ultimately arises will depend on the precise facts, but the recipient’s lack of knowledge is not itself a complete defence.

The result is that section 160 can treat two fundamentally different cases in substantially the same way. The first is deliberate asset stripping undertaken to frustrate the CRA. The second is an innocent transfer made in the ordinary course of family life when the recipient had no reason to know that the transferor owed, or might later be found to owe, tax. A sound anti-avoidance rule should distinguish between them. Section 160 largely does not.

Why Unlimited Exposure Is Unfair

The absence of any assessment deadline creates three related problems.

First, evidence deteriorates. A transferee assessed many years later may be required to prove what property was received, its value at the time, the consideration provided and the transferor’s underlying tax position. Bank records may no longer exist. Documents may have been destroyed in accordance with ordinary retention practices. Witnesses may have died, become unavailable or simply forgotten the details. Yet the assessment arrives with the usual presumption of validity, leaving the transferee to reconstruct a transaction the Crown was entitled to leave untouched for an unlimited period.

Second, the rule undermines finality. Limitation periods are not technical favours to taxpayers. They reflect a basic legal judgment that potential claims should eventually become settled so people can organize their affairs. Parliament has created normal reassessment periods for direct tax liabilities and time limits for most taxpayer remedies. It is difficult to explain why a person’s exposure to another taxpayer’s debt should remain open forever, particularly where the recipient was not complicit in avoidance.

Third, unlimited strict liability can be disproportionate. The recipient may have spent the funds long ago on family needs, education, housing or medical expenses. The transferred asset may have declined in value or disappeared. The CRA is nevertheless collecting from the recipient’s present assets based on a historic transfer. The provision is described as preserving value, but in a delayed assessment it may operate less like tracing and more like an indefinite personal guarantee that the recipient never agreed to provide.

Recent Amendments Make the Imbalance Harder to Defend

Parliament has already strengthened section 160. The current rules contain broad anti-avoidance measures addressing transactions or series designed to avoid transferee liability, including indirect arrangements and attempts to manipulate the relevant consideration. Section 160.01 can also impose a substantial penalty on persons who engage in section 160 avoidance planning and knew, or would reasonably be expected to know but for gross negligence, what the planning sought to accomplish.

Those measures show that the Act can distinguish deliberate avoidance from innocent conduct. They also weaken the argument that an unlimited assessment power is necessary in every case. Parliament now has targeted tools for sophisticated planning and culpable participation. It should use those tools aggressively where appropriate, while narrowing the collateral exposure of ordinary recipients.

A Better Model

The solution is not to repeal section 160 or to make subjective intention an element of every assessment. Either change would invite disputes and could reward carefully concealed avoidance. The better approach is a two-track rule built around finality, knowledge and preservation of the Crown’s collection rights.

First, Parliament should enact a general limitation period. The Minister should be required to assess a transferee within six years after the later of the transfer and the date on which the transferor’s relevant tax liability is assessed. Six years is long enough to accommodate most audits, objections and collection reviews, while still giving families and businesses a point at which ordinary transactions become final. Where the underlying tax liability is changed on objection or appeal, the Minister should retain a defined consequential period to adjust the transferee assessment.

Second, the limitation period should not protect collusion. An extended period, or no limitation period, should remain available where the Minister proves that the transferee knowingly participated in a transaction intended to defeat collection, was wilfully blind to that purpose, or made a misrepresentation attributable to fraud, neglect or wilful default concerning the transfer. The burden for invoking the exceptional period should rest with the Crown. This would preserve a strong remedy for real avoidance without presuming culpability merely from a family relationship.

Third, Parliament should add a due diligence defence for individual transferees. Relief should be available where the recipient establishes that they did not know, and could not reasonably have known, of the transferor’s existing or reasonably foreseeable tax liability or of a purpose to impair collection, and that they acted reasonably in the circumstances. Relevant factors could include the nature of the relationship, the size and character of the transfer, the recipient’s involvement in the transferor’s financial affairs, whether professional advice was obtained and whether the transaction was consistent with an established pattern of family support.

Fourth, the legislation should permit value-based relief where the recipient no longer retains the benefit and did not participate in avoidance. This should not become an automatic exemption whenever money has been spent. It could instead authorize the Tax Court to reduce liability where full enforcement would be manifestly disproportionate, having regard to the recipient’s good faith, the use of the property, the delay in assessment, prejudice caused by lost evidence and the CRA’s collection efforts against the original debtor.

Fifth, a transferee should receive meaningful access to the basis of the underlying tax debt. Although a transferee may challenge the underlying liability when appealing a section 160 assessment, that right is of limited value if the relevant audit records, assumptions and supporting documents are unavailable. The Act should require the Minister, subject to appropriate privacy protections, to disclose the material necessary to understand and contest both the transferor’s liability and the alleged transfer.

The Proposed Balance

The reform can be stated simply. Ordinary cases should have an ordinary end date. Fraudulent or collusive cases should not. Innocent recipients should have a genuine defence. Deliberate participants should remain fully exposed.

This structure would improve administration as well as fairness. A clear deadline would encourage the CRA to identify potential transferee cases while records remain available. A defined culpability exception would concentrate litigation on conduct that actually threatens the tax base. A due diligence defence would give courts a principled basis to separate family members who assisted in avoidance from those who merely received an ordinary benefit without knowledge of a hidden tax problem.

Most importantly, reform would restore proportionality. The state has a legitimate interest in preventing tax debtors from making themselves judgment-proof. That interest does not require every non-arm’s-length recipient to live indefinitely under the possibility of inheriting someone else’s tax debt.

Conclusion

Section 160 addresses a real abuse, but it does so with a rule that is broader and more permanent than necessary. Its unlimited assessment period, coupled with the absence of a general knowledge requirement or due diligence defence, can transform an innocent family transaction into a tax liability many years later. By that point, records may be gone, the benefit may have been consumed and the recipient may have had no connection to the conduct that produced the underlying debt.

Parliament should retain a forceful transferee liability rule. It should also recognize that effective collection and basic fairness are not opposing goals. A six-year limitation period, a robust exception for knowing avoidance, a due diligence defence, limited proportionality relief and proper disclosure of the underlying case would protect the fisc without imposing perpetual liability on the innocent. A tax debt should not become immortal merely because property once passed between family members.
