It’s March.
Your accountant is buried.
Your bookkeeper is juggling deadlines.
Documents are flying across inboxes faster than anyone can track.
Everyone’s head is down, just trying to get through the month.
You already know this.
But hackers know it too.
Security researchers consistently see a spike in phishing attempts during tax season, with March bringing roughly a 28% increase in tax-themed scam emails compared to quieter months. These emails aren’t dramatic or obvious.
They’re designed to blend in.
And they arrive exactly when people are busiest.
That’s not coincidence.
That’s timing.
At Mirrored Storage, we see the same pattern every year through the businesses we support. Our security and continuity specialist Brook often reminds clients of a simple truth:
“Hackers rarely break systems.
They break routines.”
And tax season is when routines get stretched thin.
Let’s talk about what’s happening — 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 entire ecosystem around them.
When tax season hits:
• Clients rush to send sensitive documents
• Staff shortcut normal checks to keep up with volume
• “Just send me the file” replaces usual caution
• Verification gets skipped because everyone is slammed
Everything speeds up.
And speed is where mistakes happen.
Cybercriminals don’t hunt calm, methodical organizations.
They hunt busy ones.
March is busy.
What These Attacks Actually Look Like
Most phishing attacks don’t look like scams.
They look like normal business.
For example:
• An email from “your accountant” asking you to resend W-2s because something didn’t come through
• A vendor message saying their banking details have changed
• A DocuSign request for a tax document that “needs your signature today”
• An urgent message from “your CEO” who is traveling and needs help quickly
Nothing about these messages screams “hack.”
They simply match the rhythm of a busy office during tax season.
That’s why they work.
Why Busy People Get Caught
This isn’t about being careless.
It’s about being human.
When inboxes are overflowing and deadlines are tight, people don’t read every detail.
They scan.
They assume.
They react.
Scammers know this.
Their messages are built for people who are moving just a little 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 March, almost everyone is.
Four Simple Ways to Not Be the Easy Target
The good news?
You don’t need complex security tools or a full IT department to dramatically reduce risk.
You just need a few intentional habits — especially 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 the vendor using a number you already trust and confirm it verbally.
This one 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 requests W-2s, tax documents, or financial files “right now,” take a moment to verify.
The real sender won’t mind a short delay.
A scammer will.
3. Confirm “urgent” requests through a second channel
If something feels urgent, verify it another way.
A quick call, text, or internal chat message can stop a bad decision before it starts.
Real urgency survives a two-minute check.
Fake urgency doesn’t.
4. Give your team a five-minute heads-up
Sometimes the best security tool is simply awareness.
This week, remind your team that tax season is prime time for phishing scams.
Let them know it’s okay to slow down, double-check, and ask questions when something feels off.
That small cultural shift can prevent a lot of cleanup later.
At Mirrored Storage, Brook often tells business owners:
“Good cybersecurity isn’t about paranoia.
It’s about creating a workplace where people feel safe slowing down long enough to verify.”
The Takeaway
Tax season is stressful enough without adding “fell for a scam” to the list.
The attacks showing up this month aren’t particularly clever.
They’re simply well timed.
They rely on:
• People being rushed
• Assumptions replacing verification
• Teams trying to power through March
The good news is you don’t need to overhaul your systems to stay safe.
Often, the most effective defense is simply slowing down when something feels urgent and verifying before acting.
That small pause can save a business from a very expensive mistake.
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, it may be worth a quick check.
