The CRA asked you to complete a net worth or personal expenditure questionnaire?
These questionnaires become the foundation of the assessment. Get advice before completing them; errors and omissions can add significant unreported income to the CRA's calculation.
How a Net Worth Audit Works
Subsection 152(7) of the Income Tax Act allows the CRA to assess tax without being bound by the return filed. Where records are missing or unreliable, or where the CRA believes income has gone unreported, auditors may use an indirect method. The most common is the net worth method: the CRA calculates your net worth (assets minus liabilities) at the beginning and end of each year, adds your estimated personal spending, and subtracts the income you reported and non-taxable sources. Anything left over is treated as unreported income.
Courts have described the net worth method as a blunt instrument of last resort. It produces an estimate, not a precise figure, and small errors compound across years. Yet because the CRA's assumptions are presumed correct in a tax appeal, the taxpayer must show where the estimate is wrong.
Common Errors in CRA Net Worth Calculations
In our experience, net worth assessments frequently overstate income because the CRA does not know about legitimate non-taxable sources of funds or double-counts transfers. Each error, once proven, reduces the assessment.
- Gifts and loans from family, often from abroad, not accounted for
- Inheritances and proceeds from the sale of assets outside Canada
- Transfers between your own accounts counted as new deposits
- Cash savings that existed before the audit period ignored
- Personal expenditures estimated using Statistics Canada averages rather than your actual spending
- Loan proceeds, credit card advances and refinancing treated as income
- Asset values or opening balances misstated
- Spouse's or family members' income and assets attributed to you
Penalties and the Time Limit
Net worth assessments are often accompanied by gross negligence penalties under subsection 163(2), which can equal 50% of the tax on the unreported income. For these penalties, the burden is on the CRA to prove that you knowingly, or in circumstances amounting to gross negligence, made a false statement or omission.
Net worth audits often reach back beyond the normal three-year reassessment period. To reassess statute-barred years, the CRA must prove misrepresentation attributable to neglect, carelessness, wilful default or fraud. Challenging the CRA's ability to reopen old years can eliminate a large part of an assessment.
Building Your Defence
Successful net worth defences are built on documents. We work to reconstruct the true story of your finances: bank and loan records, proof of foreign funds, documentation of family support, affidavits from family members, and evidence of actual living costs. Where documents are incomplete, credible testimony supported by circumstantial evidence can also be accepted by the Tax Court.
Because net worth audits can uncover issues that raise criminal concerns, we also assess whether there is any risk of a referral to the CRA's Criminal Investigations Program and protect your rights accordingly.
What to Do if You Receive a Net Worth Proposal
Before an assessment issues, the auditor usually sends a proposal letter with the net worth statement and invites a response within a set time. This is a valuable opportunity. Request the auditor's working papers so that each figure can be traced to its source. Check every asset, liability and opening balance, and identify every non-taxable source of funds the CRA has missed. A detailed written response, supported by documents, can substantially reduce or eliminate the proposed adjustments before they become an assessment.
Avoid providing new explanations without considering how they fit the whole picture. Inconsistent or shifting explanations damage credibility, which is often decisive in a net worth case at the Tax Court. We prepare responses that present a single, coherent and documented account of your finances.

Frequently Asked Questions
Why is the CRA doing a net worth audit on me?
Net worth audits are typically used when records are incomplete, when spending or asset growth appears inconsistent with reported income, or in cash-intensive businesses. Third-party information such as property purchases can also trigger them.
My family gave me money from overseas. How do I prove it?
Bank transfer records, letters, foreign bank statements, and affidavits from the people who gave the funds can help. Even partial documentation, combined with credible testimony, can be persuasive.
Who has to prove the income was or was not earned?
For the tax itself, you generally must show the CRA's assumptions are wrong. For gross negligence penalties and for reopening statute-barred years, the burden shifts to the CRA.
Can a net worth audit lead to criminal charges?
It can if the CRA believes there was deliberate evasion. Most net worth audits are civil matters, but legal advice early on protects your rights if the file changes direction.
Can the CRA use statistical averages for my living expenses?
Auditors sometimes use Statistics Canada data to estimate personal spending when actual figures are not available. Providing evidence of your actual expenses, which are often lower, can significantly reduce the assessment.
Should I answer the CRA's net worth questionnaire?
You may be required to provide information, but the questionnaire should be completed carefully and accurately, ideally with legal advice. Omissions, estimates and inconsistent answers can increase the assessment and damage credibility.
