When the Canada Revenue Agency cannot reconcile a taxpayer's lifestyle with the income reported on their returns, it frequently abandons the books and records altogether and rebuilds income using the net worth method. The decision in Halls v. The Queen, 2022 TCC 14, is a useful, recent illustration of how the Tax Court of Canada handles these appeals and, just as importantly, what a taxpayer must actually do to knock down the assessment. The taxpayer in Halls lost, and the reasons she lost are precisely the lessons every taxpayer facing an indirect-income reassessment needs to understand before walking into Court.
This article looks at what the net worth method is, what happened in Halls, and the practical steps that separate a successful challenge from an unsuccessful one.
The facts
Ms. Halls operated a barbecue restaurant. The CRA reviewed her affairs and concluded that her records were not adequate to verify the income she had reported. Where a business co-mingles personal and business funds and does not keep complete, reliable books, the CRA is left without a dependable way to confirm reported income directly. In that situation the Agency turned to the net worth method.
The net worth method is an indirect way of estimating income. Instead of adding up sales from the books, the auditor measures the increase in a taxpayer's net worth (assets minus liabilities) from the beginning to the end of a year, adds back personal expenditures and non-deductible outlays, and then subtracts amounts the taxpayer can show came from non-taxable sources. The figure that remains is treated as income for the year. If that figure exceeds what the taxpayer reported, the difference is assessed as unreported income.
On that basis, the CRA reassessed Ms. Halls to add unreported income for the years under review and initially levied penalties. By the time the matter reached the Tax Court, the disputed amounts had already been adjusted at the objection stage based on additional information she had provided, and the penalties had been reconsidered. What remained was her challenge to the net worth assessment itself.
The issue
The core question was straightforward: had the CRA been entitled to use the net worth method, and had Ms. Halls shown that the resulting assessment was wrong?
That framing reflects a feature of Canadian tax litigation that surprises many taxpayers. In an income tax appeal, the Minister's assessment rests on assumptions of fact, and the taxpayer bears the initial onus of demolishing those assumptions. The Supreme Court of Canada described this allocation of the burden in Hickman Motors Ltd. v. Canada, [1997] 2 S.C.R. 336: the taxpayer must first make a prima facie case displacing the Minister's assumptions, and only then does the onus shift to the Crown. A net worth appeal does not change that starting point. The CRA does not have to prove the taxpayer earned the income; the taxpayer has to prove the CRA's reconstruction is incorrect.
This is why the net worth method is so difficult to attack with generalities. The courts have long acknowledged that net worth is a rough tool. In the often-cited words of the Tax Court in Ramey v. The Queen, the net worth method is "an unsatisfactory and imprecise way" of determining income and "a blunt instrument" of last resort. But being imprecise is not the same as being wrong in a way the taxpayer can demonstrate. Establishing that the instrument is blunt does not, by itself, establish that the number it produced is too high.
What the Court decided (and why)
Justice Masse dismissed the appeal and upheld the CRA's use of the net worth method.
The Court accepted that the method was appropriately resorted to because Ms. Halls had not maintained adequate or complete records and had co-mingled her personal and business finances. Where reliable books do not exist, the CRA is justified in turning to an indirect method; the taxpayer cannot create a records gap and then complain that the CRA filled it.
On the substance, the decision turned on what Ms. Halls did not do. Courts have recognized that a taxpayer can attack a net worth assessment in essentially three ways, a framework reflected in cases such as Truong v. The Queen, 2017 TCC 22:
- Challenge the use of the method itself — argue that the CRA had no proper basis to abandon the books and resort to an indirect approach.
- Challenge specific components of the calculation — show that a particular asset, liability, personal-expenditure estimate, or opening net worth figure is wrong, and by how much.
- Prove non-taxable sources — produce evidence that an identified part of the increase in net worth came from non-taxable sources such as gifts, inheritances, loans, or accumulated savings, so it should be removed from income.
Ms. Halls challenged the assessment in a general way rather than dismantling specific figures. She did not establish that the method should not have been used, given her poor record-keeping. She did not point to particular line items in the auditor's calculation and show they were mistaken. And she did not identify any significant non-taxable source that should have reduced the assessed amount. Many of the specific concerns she had raised earlier had already been addressed at the objection stage, where the appeals officer adjusted the disputed amounts on the strength of the further information she supplied. What was left before the Court was a broad objection to the methodology, which is not enough to meet the taxpayer's onus.
Because she had not demolished the Minister's assumptions, the burden never shifted to the Crown, and the assessment stood.
Why this decision matters / practical takeaways
Halls is not a dramatic change in the law. Its value is that it shows, in one compact set of reasons, the exact ground on which net worth appeals are won and lost. The practical lessons are concrete:
- Records are the first battle. The single most common reason the CRA can resort to the net worth method is inadequate books. Maintaining complete records, and keeping business and personal funds separate, removes the Agency's justification for an indirect assessment in the first place.
- Generalities do not win. Arguing that the net worth method is "unfair" or "imprecise" restates settled law that the courts already accept — and lose on. A successful appeal attacks specific numbers: a wrong opening net worth, a double-counted asset, an inflated personal-expenditure estimate, a liability the CRA ignored.
- Non-taxable sources must be proven, not asserted. Claims that a deposit was a gift, an inheritance, a loan from family, or drawn-down savings are powerful — but only with documentation. Bank records, loan agreements, gift letters, and a traceable money trail are what move the number, and the taxpayer who can identify and substantiate a non-taxable source can have it removed from income.
- The burden is on the taxpayer. Because the taxpayer carries the initial onus, preparation and evidence-gathering are decisive. A net worth file is built on documents and a coherent narrative, not on cross-examination of the auditor alone.
- Penalties are a separate fight. Even where unreported income is found, gross negligence penalties under subsection 163(2) are not automatic. As the Federal Court of Appeal explained in Lacroix v. Canada, 2008 FCA 241, a penalty can follow where the discrepancy remains unexplained and the taxpayer's account is not credible — but the Crown bears the burden on penalties, and that burden is distinct from the merits of the net worth calculation itself.

How Barrett Tax Law approaches net worth audit files
A net worth assessment is, at bottom, an argument about numbers and where money came from. Our approach is to treat it that way from the start. Working alongside taxpayers facing net worth audits, we typically begin by reconstructing the CRA's calculation line by line to find the components most vulnerable to challenge — an overstated opening position, omitted liabilities, or personal-expenditure estimates that do not match the taxpayer's real circumstances.
From there the focus shifts to evidence: identifying and documenting genuine non-taxable sources so they can be removed from income, and assembling the records needed to show the assessment is overstated. Where the file is still at the audit or objection stage, that work often resolves issues before they ever reach a courtroom, as part of broader audit representation. Where litigation is necessary, the same groundwork supports an appeal to the Tax Court of Canada. And because indirect assessments so often arrive with gross negligence penalties attached, we treat the penalty as its own issue with its own, separate burden on the Crown. If you are facing a net worth reassessment, a free consultation is a sensible first step to understand your options.

Frequently asked questions
What is the net worth method of assessment?
It is an indirect way for the CRA to estimate income when a taxpayer's books are unreliable or incomplete. Instead of totalling sales from the records, the auditor measures the change in the taxpayer's net worth (assets minus liabilities) over a year, adds personal and non-deductible expenditures, and subtracts proven non-taxable amounts. The result is treated as income, and any excess over what was reported is assessed as unreported income.
Who has the burden of proof in a net worth appeal?
The taxpayer carries the initial onus. As the Supreme Court of Canada explained in Hickman Motors Ltd. v. Canada, the taxpayer must make a prima facie case demolishing the Minister's assumptions of fact before the burden shifts to the Crown. Simply arguing that the net worth method is imprecise is not enough; the taxpayer must show that the specific figures are wrong.
How can a taxpayer challenge a net worth assessment?
Courts recognize roughly three approaches, reflected in cases like Truong v. The Queen, 2017 TCC 22: dispute whether the CRA was entitled to use the method at all, attack specific components of the calculation (such as the opening net worth, particular assets, or personal-expenditure estimates), or prove that part of the net worth increase came from non-taxable sources such as gifts, loans, inheritances, or savings.
Why did the taxpayer lose in Halls v. The Queen?
Justice Masse found that Ms. Halls had not maintained adequate records, which justified the CRA's resort to the net worth method, and that she challenged the assessment only in general terms. She did not dismantle specific figures in the calculation or identify and document significant non-taxable sources of income, so she failed to meet her burden and the assessment was upheld.
Are gross negligence penalties automatic when unreported income is found?
No. Penalties under subsection 163(2) are a separate question from the merits of the net worth calculation, and the Crown bears the burden of justifying them. As the Federal Court of Appeal noted in Lacroix v. Canada, 2008 FCA 241, a penalty may follow where a discrepancy is unexplained and the taxpayer's explanation is not credible, but a finding of unreported income does not, on its own, automatically support a gross negligence penalty.
What is the most effective way to prepare for a net worth audit or appeal?
Documentation. Reconstruct the CRA's calculation to find vulnerable components, gather records that show specific figures are overstated, and substantiate any non-taxable sources with bank records, loan agreements, and a traceable money trail. Because the taxpayer bears the initial onus, building this evidence early, ideally at the audit or objection stage, is what most often changes the outcome.
