How to Handle CRA Notice of Objection for Cryptocurrency Tax Reassessments (Part iii): Managing CRA Tax Audit Risk and CRA Tax Reassessment Exposure

By: Crypto Tax Lawyer

Published: January 14, 2026

CRA Tax Audits and Cryptocurrency Transactions Leading to CRA Tax Reassessments

CRA tax audits involving cryptocurrency frequently arise from discrepancies between reported income and third-party information obtained from cryptocurrency exchanges, blockchain analytics, or financial institutions. Auditors focus on transaction frequency, wallet activity, and documentation supporting reported losses. These audits often result in a CRA tax reassessment recharacterizing cryptocurrency gains or denying losses.

Filing a Notice of Objection After a CRA Tax Reassessment Involving Cryptocurrency

A notice of objection is the statutory mechanism for challenging a CRA tax reassessment involving cryptocurrency. It must be filed within prescribed time limits, subject to limited extension-of-time relief. The notice of objection should clearly set out the disputed issues and legal grounds, as it frames the dispute for CRA Appeals and potential Tax Court of Canada litigation.

Burden of Proof in CRA Tax Audits and Cryptocurrency Tax Litigation

In cryptocurrency-related tax disputes, the burden of proof generally rests with the taxpayer. This requires credible evidence to refute the factual assumptions underlying the CRA tax reassessment, including transaction records, exchange data, and explanations regarding trading intent.

Role of a Canadian Tax Litigation Lawyer in CRA Cryptocurrency Disputes

An experienced cryptocurrency tax lawyer can assist taxpayers in navigating CRA tax audits, drafting effective notices of objection, and determining whether resolution through CRA Appeals or litigation before the Tax Court of Canada is appropriate.

  • Maintain complete cryptocurrency transaction records and wallet histories.
  • Respond strategically to CRA tax audit information requests
  •  File a notice of objection on time to preserve appeal rights.
  • Seek advice from a Canadian crypto tax expert early.
