How to reduce stress when CRA comes calling

By Mary Loggan

For many farmers, receiving a letter from the Canada Revenue Agency (CRA) can raise immediate concern.

Audits are often associated with major issues or penalties. In reality, most farm financial reviews are routine and focused on specific areas rather than a full examination of the entire operation.

Still, the process can feel time-consuming and uncertain without the right preparation.

Understanding what triggers an audit, what information is required, and how to respond can make a significant difference.

Jennifer McArthur, CPA, CA and partner with Ward & Uptigrove Chartered Professional Accountants in Listowel, says that while audits are not always avoidable, strong recordkeeping and a clear approach can make them far more manageable.

What triggers a farm financial audit?

When it comes to farm audits, many producers ask what causes CRA to take a closer look.

According to McArthur, most reviews are driven by specific flags or patterns in financial reporting rather than broad concerns about the entire business.

“The CRA most commonly reviews farms in a couple of key areas,” she explains.

“One of the most frequent reviews is of an HST return. Another common trigger is when CRA looks more closely at a specific line item on a corporate tax return.”

HST filings are a common starting point, particularly when there are noticeable changes compared to previous years.

“An HST review may happen if there is a noticeable increase in your HST claim compared to your normal average.

Even legitimate increases — such as those tied to major purchases — can prompt a review if they fall outside typical patterns.”

CRA also periodically focuses on certain expense categories across industries, including agriculture.

“Recently, these have included mobile equipment purchases like tractors and self-propelled equipment, regional opportunities investment credits, professional fees, and automotive expenses,” she says.

While targeted reviews are most common, broader audits do happen.

“CRA can also review or audit other areas such as payroll deductions, housing or vehicle benefits reported on T4s, or even complete a full review of all your financial information,” McArthur explains.

Not every audit is triggered by a red flag.

“In some cases, reviews are simply selected at random through CRA’s internal systems.”

Behind the scenes, audit selection has become more data-driven.

According to the CRA, compliance programs now rely heavily on risk assessment tools and data analytics to identify unusual patterns or inconsistencies in tax filings.

This allows auditors to focus on higher-risk files while still maintaining some level of random selection.

Audit activity overall remains significant.

CRA departmental reporting indicates that the agency carries out hundreds of thousands of compliance actions each year — including audits, reviews, and examinations — across all sectors.

While agriculture represents just one segment, farm businesses are regularly included in this broader compliance effort.

Getting your records audit-ready

If a farm receives an audit letter, preparation should begin immediately — but calmly — with a focus on clarity and completeness.

“If you receive a letter from CRA, there are two main things you will want to have ready right away,” says McArthur.

“First, prepare a clear listing of expenses or HST paid and collected that supports the amounts being reviewed. This information can usually be pulled directly from your bookkeeping software.”

That summary provides the framework, but the documentation supports it.

“Second, gather the invoices that back up those numbers.

Having both the summary and the source documents ready will make the process much smoother.”

The way information is presented can directly impact how quickly an audit progresses.

“When submitting information to CRA, starting with a short cover letter that clearly answers their questions can go a long way.

From there, include your bookkeeping reports with clear references to the invoices that support them.”

Presentation matters just as much as content.

“Make sure all invoice copies are easy to read and that names, dates, and amounts are clear.

The easier you make it for the auditor to follow the trail, the quicker and more smoothly the review will be completed.”

Strong recordkeeping habits long before an audit occurs can significantly reduce stress.

According to Farm Credit Canada (FCC), maintaining accurate, up-to-date financial records is a core part of farm risk management, helping with compliance, day-to-day financial decision-making, and long-term planning.

McArthur also recommends taking a proactive approach to organising major expenses.

Keeping separate files for large building projects and significant equipment purchases can make it easier to respond if those items are reviewed, especially in years with higher capital investment.

Common mistakes & how to handle them on your farm

Many audit challenges stem from simple bookkeeping errors rather than complex financial issues.

“Some of the most common problems we see are simple bookkeeping errors,” says McArthur.

“One frequent issue is claiming HST when there is no HST on the invoice.”

Some goods and services are zero-rated or exempt, and discrepancies quickly become apparent when invoices are reviewed alongside claims.

Another common issue is incorrect business identification.

“A common mistake is invoices not being made out to the correct business name.

When incurring expenses or purchasing assets, make sure the invoice matches the legal name of the business — whether that’s the farmer’s personal name for a sole proprietorship or the registered company name if the farm operates as a corporation.”

Even small inconsistencies can create delays, additional questions, or adjustments during an audit, which is why accuracy in everyday bookkeeping is so important.

If an error is discovered during the audit process, McArthur emphasises that transparency is the best approach.

“Finding a mistake can make anyone nervous, but honesty really is the best approach.

Being upfront with the auditor about an error allows them to review it and move forward.”

It is also important to follow the auditor’s lead rather than making assumptions.

“Let the auditor know what was found and wait for their direction — either they will ask you to correct it, or they will adjust it as part of the review.”

Clear communication helps prevent future complications.

“Be sure to get clarity on how the correction will be handled so it does not create further issues down the road,” she adds.

While audits can feel disruptive, they are often more manageable than expected with the right approach.

“CRA reviews cannot always be avoided, but they are usually far less stressful than expected.”

McArthur points to a few practical habits that can make a meaningful difference: keeping records organised and complete so invoices are easy to find, maintaining separate files for large building projects and major equipment purchases, and working with an accountant who can communicate directly with CRA, submit documentation, and act as an advocate throughout the process.

“With strong systems in place and a clear understanding of what CRA looks for, farm businesses can approach audits with greater confidence — and keep the focus on running their operation.” BF
