Bill-C31: Proposed Changes to CRA Audit and Enforcement Powers

Tuesday July 28, 2026

The Canada Revenue Agency’s audit and enforcement powers are set to expand significantly. On May 6, 2026, the federal government tabled Bill C-31, proposing amendments to the Income Tax Act that would strengthen the CRA’s ability to gather information and enforce compliance during audits. For business owners, the takeaway is straightforward: the CRA may soon have greater authority to request information, impose penalties, and extend reassessment timelines while compliance issues remain unresolved.

Here’s What You Need to Know

Key Proposed Changes

A new Notice of Non-Compliance (NoNC) could be issued when a taxpayer fails to comply with an information request, with no minimum threshold required. The CRA would also gain expanded authority to obtain information, including foreign-based information tied to international tax agreements.

New Penalties for Non-Compliance

  • A daily penalty of $50 (up to a maximum of $25,000) applies for each day a NoNC remains outstanding.
  • A penalty of 10% of the aggregate tax payable for a taxation year applies when the CRA successfully obtains a compliance order, provided the tax owing exceeds $50,000 for that year.
  • No penalty applies where non-compliance is based on a reasonable belief that solicitor-client privilege protects the information.

Extended Reassessment Periods

Currently, the reassessment period is suspended only when a taxpayer seeks judicial review of certain requirements or a compliance order proceeding has begun. Bill C-31 expands these triggers to also include periods while a NoNC is outstanding, and this suspension applies to the taxpayer and to non-arm’s length persons alike. As a result, the CRA’s window to reassess can remain open considerably longer while a dispute is unresolved.
