Your Accountant Is Stressed. Hackers Know It.

It's late March.
Your accountant is buried. Your bookkeeper is scrambling. Deadlines are looming. Emails are flying faster than anyone can keep up.
Everyone's head is down, just trying to get through to April 30.
This isn't news to you.
But it isn't news to hackers either.
In 2024, Canadians lost a record $638 million to scams, with the Canada Revenue Agency (CRA) warning that tax season brings a significant spike in phishing attempts. Cybercriminals know that during tax season, March and April specifically, people are busiest, emails are flying, and normal verification processes get shortcut. These messages aren't dramatic—they're designed to blend in with everyday business requests, right when people are most distracted.
That's not coincidence.
That's timing.
Here's what's coming and four simple ways to make sure your business isn't the easy target.
The Stressed Supply Chain
Here's what most people miss:
Hackers aren't just targeting accounting firms.
They're targeting the chaos around them.
When tax season hits:
Clients rush to send sensitive documents
Staff members shortcut normal checks to keep up with volume
"Just send me the file" replaces usual caution
Verification gets skipped because everyone is slammed
The whole ecosystem speeds up.
And speed is where mistakes happen.
Hackers don't go after calm, methodical businesses. They go after busy ones.
Late March and April are busy.
What These Attacks Actually Look Like
This isn't a movie plot.
It's an email that looks exactly like the others in your inbox.
A message from "your accountant" asking you to resend T4s because something didn't come through.
A note from a vendor saying their bank information has changed and needs updating.
A DocuSign request for a tax document that "needs your signature today".
An urgent email from "your CEO" who's traveling and needs help immediately.
None of these feel suspicious.
They feel like normal business in late March and April.
That's why they work.
Why Busy People Get Caught
This isn't about being careless. It's about being human.
When inboxes are full and the April 30 deadline is approaching, people don't read carefully. They scan. They assume. They react.
Scammers know this.
Their messages are designed for people who are moving too fast to notice the one detail that's off. They don't need you to be reckless. They just need you to be busy.
And in late March and April, almost everyone is.
Four Simple Ways to Not Be the Easy Target
The good news is you don't need fancy tools or a security team to reduce your risk.
You just need a few intentional habits during busy months.
1. Verify payment changes by phone
If an email says a vendor's banking details have changed, don't reply to the message. Call a number you already trust and confirm it verbally. This single habit prevents some of the most expensive scams businesses face.
2. Slow down requests for sensitive information
Urgency should be a signal to pause, not to rush. If someone asks for T4s, tax documents or financial files "right now," take a moment to verify first. The real sender won't mind a short delay. A scammer will.
3. Confirm "urgent" requests through a second channel
If an email claims something is urgent, verify it another way. A quick call, text or internal message can stop a bad decision before it starts. Real urgency can survive a two-minute check. Fake urgency can't.
4. Give your team a five-minute heads-up
This week, remind your team that tax season is prime time for scams. Tell them it's okay to slow down, double-check and ask questions when something feels off. That small permission shift can prevent a lot of unnecessary cleanup later.
The Takeaway
Tax season is stressful enough without adding "fell for a scam" to the list.
The attacks that show up during tax season aren't especially clever. They're just well-timed.
They rely on people being rushed.
They rely on assumptions.
They rely on everyone trying to power through to April 30.
You don't have to overhaul your systems to avoid becoming the easy target.
You just have to slow down when it matters and verify when things feel urgent.
That's often enough.
A Quick Busy-Season Sanity Check
Your business may already have good habits in place, and if it does, that's great.
But if tax season tends to push everyone into reactive mode, or you're not sure how your team handles urgent requests under pressure, it may be worth a quick sanity check with a free 15-minute consult call.
No scare tactics. No pressure. Just a clear look at whether small habits could prevent big headaches this time of year.
If this doesn't sound like your business, feel free to forward it to someone it does.
