The letter arrived on a Thursday.
Wendy almost didn’t open it. The CRA return address was enough to make her stomach drop. She set it on the corner of her desk and spent the next twenty minutes pretending to work before finally breaking the seal.
It was a review. A request for supporting documents related to her home office deduction from the previous tax year.
Her first instinct: panic.
Her second instinct — after she called her Number Crunchers advisor — was something she didn’t expect.
Relief.
“This is very routine,” her advisor said. “You’ve got good records. We’ll respond together. You’ll be fine.”
And she was. The review closed in three weeks with no changes to her return.
But the experience stayed with her. Because for years, the idea of a CRA review had lived in the back of her mind as something enormous and unpredictable. Something to dread.
It wasn’t. It just felt that way because she didn’t know what to expect.
Why the CRA Contacts Businesses
Getting a letter from the CRA doesn’t mean you did something wrong. It means a question came up that they’d like answered — and most of the time, that question has a straightforward answer.
CRA reviews and audits are triggered in a few common ways:
- A specific deduction or credit looks unusual relative to your income or industry
- Your return is flagged as part of a routine random selection
- Something changed significantly year over year — a big increase in expenses, a drop in revenue, or a new deduction category
- A third party’s information (like a T4A you issued) doesn’t match their own filing
- You’re in an industry the CRA is currently reviewing more closely
Being selected doesn’t imply guilt. It implies a question. The goal of any CRA contact is simply to verify that what was claimed is accurate and supported.
“A CRA review isn’t an accusation. It’s a question. And questions, when you have good records, have answers.”
Reviews vs. Audits: They’re Not the Same Thing
Most business owners use the word “audit” to describe any contact from the CRA. But in practice, there’s an important difference between a review and a full audit — and understanding that difference matters for how you respond.
|
CRA Review (Desk Review) |
Full Audit |
|
| What triggers it | Specific claim flagged; routine spot-check | Broader inconsistencies or risk indicators |
| Scope | Narrow — one or a few items | Wide — full tax return, multiple years |
| How it arrives | Letter asking for supporting documents | Letter or call requesting an in-person meeting |
| Response time | Typically, 30 days to reply | Varies; can span weeks to months |
| Who handles it | You (or your advisor on your behalf) | Strongly recommended: involve your advisor |
| Outcome if compliant | CRA confirms the claim; file closed | Assessment confirmed or adjusted |
| Outcome if not | Reassessment with possible penalties | Reassessment, penalties, interest, or appeals |
The key takeaway: Most CRA contacts are reviews, not audits. Reviews are narrower, faster, and far less disruptive — especially when your records are clean.
What Wendy Learned About the Process
When Wendy’s review letter arrived, she called her Number Crunchers advisor within the hour. That call set the tone for everything that followed.
Her advisor walked her through exactly what the CRA was asking, what documents would satisfy the request, and how to respond in a way that was complete, professional, and nothing more than what was needed.
“Don’t overshare,” her advisor told her. “Answer the question they asked. Provide the documents they requested. Be timely and accurate. That’s all this requires.”
Wendy pulled her home office records — floor plan, square footage calculation, lease, and utility bills — from the organized folder her bookkeeper had helped her build the year before. Everything was there. Nothing had to be reconstructed from memory.
Her advisor drafted the response letter. Wendy reviewed it. It went out within two weeks of the original request.
Three weeks later: confirmation that her return was accepted as filed.
“The thing I remember most,” Wendy said afterward, “was how calm I felt once I knew what was happening. The anxiety wasn’t about the CRA. It was about not knowing.”
The Five Stages of a CRA Review (Demystified)
Stage 1: The Letter Arrives
The CRA sends written communication — always. They will not call you out of nowhere to demand payment or threaten legal action. If you receive an unexpected call claiming to be from the CRA, treat it with extreme caution. Legitimate CRA contact begins on paper.
Stage 2: Read Carefully — Then Call Your Advisor
Before responding to anything, understand exactly what’s being asked. The letter will specify the tax year in question, the items under review, what documents are needed, and the response deadline. Don’t assume. Don’t panic. Read, then call.
Stage 3: Gather the Right Documents
Respond to the specific question being asked — not every document you own. For a home office review, that might mean a floor plan, lease or mortgage statement, and utility bills. For a contractor payment review, it might mean contracts, invoices, and T4As. Your advisor can help you identify exactly what’s needed.
Stage 4: Submit a Clear, Complete Response
Respond by the deadline with a professional cover letter and organized supporting documents. Your advisor can draft this response on your behalf. Keep a copy of everything you send.
Stage 5: Wait for the Outcome
The CRA will review your submission and respond in writing. In most cases, the result is one of three things: the return is confirmed as filed, a minor adjustment is made, or — rarely — a broader review is initiated. If you disagree with the outcome, you have the right to object and appeal.
How Wendy Protects Herself Going Forward
The review reinforced something Wendy already believed but now felt in her bones: clean records don’t just make tax season easier. They make any CRA interaction manageable.
After the review closed, she reviewed her habits with her Number Crunchers team and formalized a few practices she’d been doing informally:
- Every deduction has a documented business purpose — written down at the time of the expense, not reconstructed later
- Home office expenses are tracked with a consistent method, with supporting calculations kept on file
- Contractor payments over $500 are tracked and T4As are issued correctly each year
- Business and personal finances are completely separated — no shared accounts, no ambiguity
- Her Number Crunchers advisor is the first call for any CRA correspondence — before she responds to anything
“I used to think good records were about being organized,” Wendy reflected. “Now I understand they’re protection. They’re the difference between a three-week review and a three-month nightmare.”
Wendy’s CRA Correspondence Checklist
| If you receive a letter from the CRA:
• Read it fully before doing anything else • Note the tax year, items under review, and response deadline • Call your advisor immediately — before drafting any response • Gather only the documents specifically requested • Submit a clear, organized response with a cover letter by the deadline • Keep copies of everything you send • Follow up if you haven’t received a response within the expected timeframe • If you disagree with the outcome, discuss your right to object with your advisor |
Wendy’s Takeaways: CRA Reviews and Audits
- A CRA letter isn’t an accusation — it’s a request for information, and most reviews close quickly with no changes
- Reviews are narrow and document-specific; full audits are broader and less common
- Legitimate CRA contact always begins in writing — be cautious of unsolicited phone calls claiming to be CRA
- Respond to exactly what’s asked, on time, with organized supporting documents
- Clean records are your best defence — not because you expect an audit, but because they make any review straightforward
- Your advisor should be your first call when CRA correspondence arrives
