CRA Industry-Wide Project Audit — Montreal CPA Firm Near You: Sector Benchmark Compliance Defense

A CRA Industry-Wide Project Audit — also called a sector audit — is launched when the Canada Revenue Agency compares your business results to national and regional benchmarks for your industry. If your margins, expenses, cash flow, or reporting patterns fall outside CRA’s expected range, the agency assumes risk — and your file is selected for audit.
Mackisen CPA Montreal specializes in defending businesses targeted by sector-wide audits by proving that your numbers reflect commercial reality, not non-compliance.

Industry-wide audits are powerful because CRA uses statistical modeling, AI-driven algorithms, and third-party data to compare you to thousands of competitors. Your defense must be equally precise, structured, and evidence-based.

Legal Foundation

Income Tax Act s.231.1–231.2 — CRA power to require records and perform industry comparisons.
Excise Tax Act s.289 — allows CRA to test GST/HST compliance based on sector patterns.
Jurisprudence: Lac d’Amiante du Québec Ltée v. Québec (2001 SCC) — CRA cannot rely exclusively on statistical averages; it must consider taxpayer-specific commercial reality.

Learning insight: CRA’s benchmark is the starting point — not the conclusion. The conclusion depends on your documentation.

Why CRA Performs Industry-Wide Project Audits

CRA targets entire industries known for:

• Cash transactions

• High COGS volatility

• Tip income

• Subcontractors or gig workers

• Informal recordkeeping

• Rapid fluctuations in market pricing

Industries most commonly audited include:

• Restaurants, cafés, bars

• Convenience and retail stores

• Construction and renovation

• Transportation, delivery, logistics

• Hair salons, aesthetic services

• Automotive repair and used-car dealers

Learning insight: CRA compares your numbers to your competitors — Mackisen CPA compares your numbers to your reality and proves why you differ.

CRA’s Sector Audit Methodology

1. CRA builds an industry benchmark (gross margin, COGS, cash ratios, payroll ratios).

2. CRA flags businesses whose numbers fall outside expected ranges.

3. CRA requests POS data, supplier invoices, bank statements, and deposit records.

4. CRA may use indirect methods such as:

   • Bank deposit analysis

   • Net-worth audits

   • Markup reconstruction

   • Supplier purchase tracing

5. CRA proposes adjustments based on unexplained differences.

Learning insight: CRA uses algorithms to ask questions — your CPA uses evidence to answer them.

Mackisen CPA’s Sector Audit Defense Strategy

• Compare your business data to CRA’s benchmark ratios to identify real causes of variance

• Reconcile POS, invoices, and bank records to match revenue and COGS

• Document unique business conditions (rent increases, supplier changes, labour shortages)

• Build CPA-certified audit binders with receipts, schedules, and explanations

• Respond directly to CRA auditors with structured, factual reports

• Prevent audit expansion by providing complete, error-free documentation

Learning insight: CRA doesn’t penalize differences — it penalizes unexplained differences. Our job is to explain them professionally.

Common Red Flags in Industry-Wide Audits

• Profit margins below or above industry averages

• Cash deposits inconsistent with reported revenue

• Supplier purchases higher than sales suggest

• Large voids, refunds, or POS irregularities

• Payroll costs too low for industry norms

• High contractor use without T4A/T5018 slips

Learning insight: Almost every red flag has a legitimate explanation — if documented properly.

Real-World Results

• A Montréal restaurant avoided a $310,000 reassessment when Mackisen CPA proved third-party delivery fees significantly reduced net margins.

• A contractor passed a sector audit after we reconciled deposit timing differences linked to project milestones.

• A retail business cleared its audit after supplier rebates and promotional pricing were properly documented and explained.

Learning insight: CRA changes its position when confronted with strong, structured facts — not emotion.
