Getting a letter from the Canada Revenue Agency saying your tax return has been selected for review is one of the most stressful things that can happen to a business owner or individual taxpayer. Most people immediately assume the worst. But a CRA audit does not automatically mean you did something wrong.
Understanding why audits happen, what they actually involve, and how to respond is important for every business owner in Canada. Being prepared makes the whole process much less scary, and having the right records in place is what ultimately protects you.
Why Does the CRA Audit Certain Returns?
The CRA uses a mix of automated systems and manual review processes to select returns for audit. Some returns are selected randomly. Others are flagged because they show unusual patterns compared to other businesses in the same industry, like claiming very high expenses relative to income. Returns can also be selected because of specific deductions that tend to attract attention, like large home office expenses, vehicle expenses, or business losses that have continued for several years in a row.
Non-resident tax situations, foreign income, and cross-border transactions also receive extra scrutiny. The CRA has specific rules around foreign tax credits and reporting of foreign assets, and errors in these areas are a common trigger for audit activity.

Types of CRA Reviews and Audits
Not every CRA contact is a full audit. The most common type is a desk review or a request for information, where the CRA simply asks you to provide documents supporting a specific line on your return. This might be receipts for a claimed deduction or a letter explaining a particular situation. Responding promptly and completely usually resolves it without any further action.
A field audit is more involved. A CRA auditor may visit your place of business or ask to meet with your accountant to go through your records in detail. This kind of audit covers multiple years and goes through your books, invoices, contracts, and bank statements.

What Records Do You Need?
The golden rule is simple: keep everything. The CRA can go back six years in most cases when reviewing your filings. That means you need to keep receipts, invoices, bank statements, contracts, vehicle logbooks, and any other documents that support what you claimed on your return.
Many business owners make the mistake of keeping poor records and hoping they will never be audited. When the CRA does come knocking, those same people find themselves in a very difficult position trying to reconstruct years of transactions from memory and incomplete files.
Cloud-based accounting systems make record keeping much easier today. When your transactions are recorded in real time and your receipts are scanned and stored digitally, you are always audit-ready. There is no last-minute scramble.
How to Respond to a CRA Letter
If you receive any communication from the CRA, the first thing to do is not panic and not ignore it. Read the letter carefully and understand exactly what they are asking for. Then contact your accountant immediately.
Many CRA audits are resolved at an early stage simply by providing the requested documents in an organized, professional way. If the CRA finds a discrepancy and wants to reassess your return, your accountant can help you understand whether the reassessment is correct and, if not, how to file a formal objection.
The Role of Professional Representation
Having a professional accountant deal with the CRA on your behalf is almost always the better approach. Accountants know how to communicate with the CRA, what information to provide, and how to respond to requests in a way that does not accidentally open up additional issues. They also know your rights as a taxpayer and can push back when the CRA’s position is incorrect.
Prevention is always better than cure. When your books are clean, your deductions are well documented, and your filings are done correctly from the start, the chances of a serious audit issue are much lower. And even if one comes, you will be in a position to handle it with confidence.
