It’s March. Your accountant is buried in filings. Your bookkeeper is juggling last-minute document requests. Deadlines are stacking up, inboxes are overflowing, and everyone is moving faster than usual just to stay afloat.
That pressure isn’t new.
But it isn’t lost on cybercriminals either.
Security researchers consistently report a noticeable spike in phishing attacks during tax season. In fact, March alone sees roughly a 28% increase in tax-themed scam emails compared to quieter months. These messages aren’t flashy or dramatic. They’re designed to look routine — blending seamlessly into the everyday back-and-forth of busy financial operations.
That timing isn’t accidental. It’s strategic.
Here’s what’s happening behind the scenes — and how to make sure your business isn’t the easy target.
The “Stressed Supply Chain” Effect
Most people assume hackers are targeting accounting firms directly.
They are — but that’s only part of the picture.
Criminals also target the businesses connected to them. When tax season hits, the entire ecosystem speeds up:
-
Clients rush to send sensitive financial documents
-
Staff members skip normal verification steps to keep pace
-
Quick file transfers replace careful review
-
Urgent requests feel routine
When everything accelerates, safeguards tend to loosen. And speed is where mistakes happen.
Hackers don’t attack calm, methodical environments. They attack high-pressure ones. March is high pressure.
What These Attacks Actually Look Like
Tax-season phishing doesn’t look like obvious fraud. It looks like business as usual.
You might see:
-
An email from “your accountant” asking you to resend W-2s because the file didn’t come through
-
A message from a vendor claiming their banking information has changed
-
A DocuSign notification requesting an urgent tax-related signature
-
An email from “the CEO” traveling and needing immediate assistance
None of these requests feel unusual in March. They feel normal.
That’s exactly why they work.
Why Smart, Busy People Still Fall for It
This isn’t about carelessness. It’s about cognitive overload.
When deadlines are tight and inboxes are packed, people stop reading closely. They skim. They assume legitimacy. They act quickly to keep things moving.
Scammers design their messages for this exact mindset. They don’t need recklessness — they just need distraction. During tax season, nearly every organization is operating in reactive mode.
And reactive mode is where phishing thrives.
Four Simple Ways to Avoid Becoming the Easy Target
You don’t need advanced cybersecurity software to reduce your exposure this month. A few disciplined habits go a long way.
1. Verify Payment Changes by Phone
If an email says a vendor’s banking details have changed, don’t respond directly to the message. Call a trusted number already on file and confirm verbally. This single practice prevents some of the most financially damaging scams businesses experience.
2. Slow Down Sensitive Document Requests
Urgency should trigger caution, not speed. If someone requests W-2s, tax records, or financial statements “ASAP,” pause and verify. A legitimate sender will understand. A scammer will pressure you.
3. Use a Second Channel for “Urgent” Emails
If something feels high stakes, confirm it another way. A quick call, internal chat, or text message can stop a costly mistake before it happens. Real urgency can withstand a two-minute verification. Fake urgency cannot.
4. Give Your Team a Five-Minute Heads-Up
Awareness is powerful. Remind your team that tax season is prime time for phishing attempts. Let them know it’s not only acceptable — but expected — to double-check unusual requests. That cultural permission can prevent major damage.
The Bigger Picture
Tax season is already demanding. Adding a security incident only compounds the stress.
The scams that spike this month aren’t technically sophisticated. They’re simply well-timed. They rely on pressure, distraction, and routine behavior.
You don’t need a major systems overhaul to avoid them. Often, slowing down at the right moments and verifying before acting is enough to eliminate the threat.
A Quick Busy-Season Sanity Check
Your business may already have solid safeguards in place. If so, you’re ahead of the curve.
But if tax season tends to push your team into reactive mode, or you’re unsure how urgent financial requests are verified under pressure, it may be worth a quick review.
A short conversation now can prevent a long cleanup later.
No scare tactics. No pressure. Just a practical look at whether small adjustments could prevent big headaches this month.
If this doesn’t sound like your organization, feel free to share it with someone who may need the reminder.
