On April 17, 2025, the Tax Court of Canada ruled on whether the Canada Revenue Agency (CRA) could reassess a taxpayer beyond the normal reassessment period for the 2014 and 2015 taxation years. The case involved omitted capital gains and incorrectly claimed capital cost allowance (CCA) and recapture, with gross negligence penalties also at issue.

Taxpayer Loses – Reassessment Permitted

The Court upheld CRA’s right to reassess outside the normal period. A key factor was a $6.1 million taxable capital gain for 2015 that was omitted from the final return. The taxpayer attributed this to an “inexplicable glitch” during the external accountant’s preparation process. Although earlier draft financial statements correctly included the gain, no one reviewed the final return before filing.

For CCA and recapture, the taxpayer argued that CRA’s failure to provide finalized undepreciated capital cost (UCC) balances—promised during prior audits—prevented accurate claims. However, the Court noted that the taxpayer filed returns without those balances and without reviewing them. Reliance on financial statements and Form T183 (used to authorize e-filing) as proxies for review was deemed insufficient. These circumstances amounted to neglect, allowing CRA to reassess beyond the normal limitation period.

Taxpayer Wins – Gross Negligence Penalties Cancelled

While the taxpayer’s conduct was negligent, the Court found it did not meet the threshold for gross negligence. Gross negligence requires a high degree of disregard for tax obligations, such as wilful blindness or mal intent. The Court emphasized the taxpayer’s longstanding reliance on internal and external accountants and the absence of egregious indifference. As a result, the gross negligence penalties were vacated.

Practical Tips to Avoid Similar Issues

1. Always Review Returns Before Filing
   Do not rely solely on financial statements or authorization forms like Form T183. Conduct a detailed review of the actual tax return.
2. Maintain Accurate UCC Records
   Track undepreciated capital cost balances internally rather than waiting for CRA confirmations.
3. Implement Internal Controls
   Establish a checklist for major items such as capital gains, CCA, and recapture to prevent omissions.
4. Document Reliance on Advisors
   Keep clear records of communications and instructions provided to external accountants to demonstrate diligence.
