CRA Personal Tax Audit 2025 — Protect Your Finances, Eliminate Penalties, and Stop CRA Stress with Mackisen CPA

In 2025, CRA’s Personal Tax Audit Division is using new AI-powered systems to cross-match every Canadian’s income, deductions, and lifestyle data. CRA’s algorithms now flag anything from side hustle income to charitable donations or medical claims that don’t align with banking activity or third-party slips. Thousands of Canadians are being audited for honest mistakes — claiming dependents incorrectly, missing a T4, or misunderstanding deduction rules. These audits can quickly lead to frozen refunds, heavy penalties, and years of financial stress. At Mackisen CPA Auditors Montreal, we defend individuals and families from CRA’s overreach. Our CPA auditors and tax lawyers handle every CRA inquiry, build your defense with evidence, and negotiate full resolution. We don’t let CRA mistakes define your financial reputation — we protect your name and your future.

Legal and Regulatory Framework

Income Tax Act (Canada)

• Section 150: Requires all taxpayers to file an accurate return annually.

• Section 162(1): Imposes late-filing penalties (5% + 1% per month).

• Section 163(2): Imposes gross negligence penalties for false statements — Mackisen prevents and reverses these.

• Section 220(3.1): Authorizes CRA to cancel or reduce penalties and interest under the Taxpayer Relief Program.

• Section 248(1): Defines allowable deductions and credits CRA often disputes during audits.
  Tax Administration Act (Quebec)
  Revenu Québec runs parallel audits on provincial tax returns, credits, and refunds. Mackisen coordinates both agencies for full compliance and consistent resolution.

Key Court Decisions

Bédard v. The Queen (2022): CRA must verify facts before denying deductions or credits.
Thibault v. The Queen (2022): Documentation provided in good faith protects taxpayers from penalties.
Guindon v. Canada (2015): Honest filing errors cannot be treated as gross negligence.
Venne v. The Queen (1984): CRA’s reassessments must be evidence-based, not assumption-driven.
These rulings confirm that CRA personal tax audits can be successfully defended with documentation, clarity, and professional advocacy.

Why CRA Targets Personal Tax Filers

CRA uses automated systems to detect “risk indicators.” Common 2025 triggers include:

• Claiming large deductions or credits.

• Failing to report secondary income (e.g., rental, gig work).

• Home office or self-employment expense claims.

• Large charitable or medical deductions.

• Mismatches between T-slips and filed returns.
  CRA assumes inaccuracy — Mackisen proves compliance.

Mackisen’s Personal Tax Audit Defense Strategy

1. Audit Risk Assessment: Review CRA’s inquiry letter and determine the audit’s scope.

2. Evidence Preparation: Gather supporting documents, receipts, and third-party verification.

3. Representation: Communicate directly with CRA on your behalf to prevent errors or escalation.

4. Objection and Resolution: File a Notice of Objection with legal and financial arguments when CRA reassesses unfairly.

5. Penalty & Interest Relief: Apply under Section 220(3.1) to cancel penalties and interest caused by misunderstanding or delay.
   Our strategy restores fairness and protects your right to accurate, lawful taxation.
