Could You Be on the CRA’s Audit Radar Without Knowing It?
As Canadians settle into the Thanksgiving long weekend, the UK’s HMRC recently reported that AI and advanced analytics helped protect or recover £10 billion in tax in 2025–26, a reminder of how data-driven tax enforcement is becoming.
Closer to home, CRA does not publish a fixed checklist of audit triggers. Selection is risk-based, drawing on data matching, industry benchmarks, third-party information and targeted compliance work.
One recurring pattern in CRA audit work is that a file is rarely selected because of one dramatic error. More often, several ordinary pieces of information begin to tell an inconsistent story.
Some of the signals that can matter include:
• Third-party information that does not match your return
• Large changes in sales, expenses or profit margins
• Operating in a cash-intensive industry
• Real estate or related-party transactions that raise questions
• Personal finances that appear inconsistent with reported income
• Previous audit adjustments, non-filing or other compliance issues
• Publicly available information, including social-media activity
The important point is that these factors do not necessarily operate in isolation. A third-party record, unusual expense pattern or lifestyle indicator may mean relatively little on its own. When several pieces fail to reconcile, however, the picture can change quickly.
Tax Tips
The best defence is not trying to guess CRA’s selection process. It is making sure your records, filings and underlying transactions can withstand scrutiny if questions arise.
If historical errors exist, consider obtaining advice about whether they can be corrected before CRA enforcement begins.
