You filed your tax return, got your refund, and moved on with your life. Eighteen months later, you get a letter from the CRA that you’re being audited. That’s the reality for more Canadians than ever.
Last year, the CRA identified $18.1 billion in unpaid taxes and penalties. Two years earlier, that number was $14.3 billion. That’s roughly a 25% jump in two years. And they’re not slowing down. Real estate audits alone jumped 17% in a single year.
The federal government keeps pumping money into CRA enforcement, including another $73 million in Budget 2024. They are spending more money to find your money.
At Blueprint Financial, we see it constantly. Clients walk in with audit problems on returns they thought were bulletproof.
And most people think audits are random. Like getting struck by lightning. They’re not. So…
How the CRA Picks You to Audit
So how do they actually decide? It starts before you even file.
The CRA uses a risk-scoring system that compares your return against benchmarks for people in similar income brackets, professions, and regions. If you’re an outlier, you get flagged.
Think of it like a filter. Your return goes through automated screening first. If something looks off, a human reviews it. If the human agrees, you get the letter.
And here’s what makes it effective. They already have your data before you file. What you earned, what you own, what you sold… they likely knew before you sat down to do your taxes.
They’re not coming after you personally. But their system is designed to catch exactly the kind of stuff regular people get wrong. Here are seven audit triggers you must be aware of, there’s a good chance at least one applies to you.
Audit Trigger 1: Your Numbers Don’t Match
The CRA already has your T4, T5, and T3 data before you file. If what you report doesn’t line up, the system flags it automatically. No human even needs to look at it.
And this trips up a lot of people who forget about small amounts. That T5 from a savings account you barely use. A T3 from a fund distribution you didn’t realize happened.
Now add this to the mix. As of January 2024, digital platforms like Airbnb, Vrbo, Uber, and Etsy are required to report your income directly to the CRA. So if you’re renting out a cottage or a basement suite and not reporting the income… they already know.
Audit Trigger 2: Your Property
Real estate is where you might be exposed without realizing it.
If you sold a residential property within 365 days of buying it, the profit is generally treated as 100% taxable business income under the anti-flipping rule. Not a capital gain. Business income. You thought you made a smart investment. The CRA thinks you’re running a business. That rule kicked off in January 1, 2023, and yes, there are exceptions for life events like job relocation, divorce, or serious illness. But the default is harsh.
And here’s one that catches a surprising number of people. Since the 2016 tax year, you’re required to report the sale of your principal residence on Schedule 3, even if the gain is completely exempt. If you don’t? The CRA can deny the principal residence exemption entirely until you file properly.
If the CRA decides you were negligent? Gross negligence penalties hit 50% of the understated tax on top of what you already owe. Between 2015 and 2023, the CRA’s real estate audit program reassessed $2.7 billion from approximately 75,000 audits.
If you own property in Canada, the CRA has more data on you than you think. Land registries, MLS data, platform reporting. They’re cross-referencing all of it.
Audit Trigger 3: Your Deductions
The CRA knows what normal looks like for your industry. Home office, vehicle, meals, travel, capital cost allowance. They have averages. If your numbers are way outside those averages, you get flagged.
Home office is the big one right now. Deductions exploded during COVID, and the CRA has been paying close attention since. The simplified $2-per-day method expired after 2022. If you’re still claiming home office, you need to use the detailed method now, and the numbers need to make sense. If you’re claiming 30% or more of your home and you’re working from a corner of your living room, that’s the kind of mismatch the CRA notices.
And if your charitable donations suddenly spike in one year? That’s a flag. Especially if it’s tied to a donation tax shelter scheme. The CRA has been cracking down on those for years.

Audit Trigger 4: Your TFSA
This one’s going to surprise people. Most Canadians think their TFSA is untouchable. It’s not.
If you’re buying and selling frequently inside your TFSA, using leverage, or trading options, the CRA can reclassify your gains as business income and tax them. Inside your “tax-free” account.
There’s a real case here. In Ahamed v. The King, a licensed investment adviser contributed the max, traded aggressively in penny stocks, and grew his TFSA to over $617,000. The Tax Court ruled it was carrying on a business. Taxable. And here’s the kicker… the Court specifically noted that unlike RRSPs, Parliament deliberately chose not to give TFSAs the same exemption from tax on business income from trading.
Audit Trigger 5: Crypto
Now, a lot of people think crypto is still the Wild West when it comes to Canadian tax. That’s changing fast.
Under the new Crypto-Asset Reporting Framework, crypto platforms in Canada started collecting your data this year. Exchanges, brokers, even crypto ATM operators. The first reports go to the CRA in 2027, covering all of your 2026 transactions. And this isn’t just Canada. Over 40 countries are implementing the same framework. The legislation is being finalized, but the framework is in motion
If you bought Bitcoin five years ago, forgot about it, sold some last year… the era of crypto anonymity from the taxman is ending.

Audit Trigger 6: The T1135
If you hold foreign property costing more than $100,000 CAD at any point in the year, you have to file a T1135. This includes U.S. brokerage accounts, foreign rental properties, and a bunch of things people don’t expect.
The penalty for not filing? $25 per day, up to $2,500 per year for a standard late filing. Gross negligence? Up to $12,000 per year. And it extends your reassessment period by three years, so your entire return stays open for six years instead of three.
And here’s how easy it is to get caught. In Moore v. The Queen (2019), Scott Moore was working at GE Capital Canada and bought U.S. shares through his employer’s stock purchase plan. Normal stuff. When GE got acquired, he moved the shares to a Canadian brokerage. That’s when he realized the cost had crossed $100,000 and he should have been filing a T1135. He came forward immediately, filed everything, wrote to the CRA voluntarily.
They hit him with a $2,500 penalty anyway. The Tax Court eventually threw it out because he’d acted in good faith. But the point is… he did everything right, came forward on his own, and still had to fight it in court.
Audit Trigger 7: International Information Sharing
Canada and the U.S. share taxpayer information automatically under FATCA. If you have U.S. accounts, the IRS tells the CRA. If you have Canadian accounts and you’re a U.S. person, the CRA tells the IRS.
But it’s not just the U.S. anymore. Through the Common Reporting Standard, the CRA now exchanges information with over 90 countries directly, and over 120 jurisdictions participate globally.
If you have money sitting in a bank account almost anywhere in the world, the CRA probably knows about it. The question is whether what you filed matches what they’ve been told.
How to Protect Yourself
Now here’s the good news. This is all manageable if you know the rules.
Keep records. If you claim it, you need to prove it. The CRA can go back 3 years normally, 6 years in specific situations, and indefinitely if they suspect fraud or you haven’t filed. Receipts, logs, documents. Boring but essential.
Don’t claim things you can’t defend. If your accountant puts something on your return and you can’t explain why it’s there, that’s a problem. You’re responsible for your return. Not your accountant. We just talked about that with the T1135.
And if you realize you’ve made a mistake? This is actually where the news has gotten better. The CRA overhauled its Voluntary Disclosure Program in October 2025. It’s more accessible than it’s been in years. If you come forward before they come to you, you can get 75% interest relief and full penalty relief. Even if the CRA has already contacted you about a potential issue, you might still qualify for the new “prompted” disclosure category with 25% interest relief. Two years ago, that contact would have disqualified you completely.
If you’ve been sitting on something, now is actually a better time to come forward than it was before.
After World War II, Switzerland was basically the world’s financial hiding spot. It took decades, but the global crackdown on bank secrecy that started around 2008 changed everything. Now over 120 countries are sharing account information. The era of ‘just put it offshore’ is done.
Conclusion
The CRA isn’t out to get you personally — but they do have more data, more funding, and more sophisticated systems than ever. If something on your return doesn’t add up, the chances of hearing from them are higher than they’ve ever been.
