Tax Season Cybersecurity Risks Every Business Should Know
It’s March.
Your accountant is buried.
Your bookkeeper is scrambling.
Deadlines are looming.
Emails are flying faster than anyone can realistically keep up with.
Everyone’s head is down, just trying to survive tax season.
This isn’t news to you.
But it isn’t news to cybercriminals either.
Security researchers consistently report a significant spike in tax season phishing attacks, with March bringing roughly a 28% increase in tax-themed scam emails compared to quieter months.
That’s not coincidence.
That’s strategy.
And if your business relies on email, financial transfers, payroll, or sensitive client data, you are part of the target pool.
The Stressed Supply Chain: Why Tax Season Increases Cybersecurity Risk
Here’s what most businesses miss:
Hackers aren’t just targeting accounting firms.
They’re targeting the entire ecosystem around them.
During tax season:
- Clients rush to send W-2s, 1099s, and financial documents
- Staff shortcut normal verification steps to keep up with volume
- “Just send me the file” replaces usual caution
- Vendor payment updates get processed quickly
- Multi-factor authentication prompts get approved without thought
The entire supply chain speeds up.
And speed is where cybersecurity mistakes happen.
Cybercriminals don’t go after calm, methodical organizations with layered IT security.
They go after busy ones.
March is busy.
What Tax Season Phishing Attacks Actually Look Like
This isn’t a dramatic Hollywood-style breach.
It’s a simple email that looks exactly like the others in your inbox.
Common tax-season cyber scams include:
- An email from “your accountant” asking you to resend payroll data
- A vendor requesting updated bank information for ACH payments
- A DocuSign notification for a “tax document that needs signing today”
- An urgent email from “your CEO” traveling and requesting immediate assistance
- A Microsoft 365 or Google Workspace login alert
None of these feel suspicious.
They feel like normal business in March.
That’s why they work.
Modern phishing attacks are designed to bypass human attention—not technical firewalls.
Why Busy Teams Are Prime Targets for Email Security Threats
This isn’t about being careless.
It’s about being human.
When:
- Inboxes are overloaded
- Deadlines are tight
- Financial documents are flying around
- Clients are demanding answers
People don’t read carefully.
They scan.
They assume.
They react.
Cybercriminals design phishing emails specifically for people moving too fast to notice the subtle red flag.
They don’t need your team to be reckless.
They just need them to be busy.
And during tax season, almost every business is.
Four Simple Ways to Strengthen Cybersecurity During Tax Season
The good news?
You don’t need a full-time security team to dramatically reduce your risk.
You need intentional habits and proactive IT support.
Here are four practical cybersecurity best practices DigeTekS recommends during busy months:
1. Verify Banking Changes by Phone
If an email says a vendor’s payment details have changed:
Do not reply to the email.
Call a known, trusted phone number and confirm the change verbally.
Business Email Compromise (BEC) scams cost businesses billions each year—and most start with a simple “bank info update” email.
One phone call prevents some of the most expensive cyber incidents companies face.
2. Slow Down Requests for Sensitive Data
If someone requests:
- W-2s
- Payroll data
- Tax returns
- Financial statements
- Login credentials
…and marks it as urgent, pause.
Urgency should trigger verification—not panic.
A legitimate sender won’t mind a short confirmation delay.
A scammer will.
3. Confirm Urgent Requests Through a Second Channel
If an email claims something is critical, verify it another way:
- Call the sender
- Send an internal Teams/Slack message
- Text the executive directly
Real urgency survives a two-minute check.
Fake urgency doesn’t.
This simple habit dramatically reduces phishing success rates.
4. Give Your Team a Five-Minute Cybersecurity Reminder
During tax season, awareness matters more than complex tools.
Tell your team:
- Phishing attacks spike in March
- It’s okay to double-check
- It’s okay to slow down
- It’s okay to question urgency
That small permission shift reduces risk more than most businesses realize.
At DigeTekS, we help businesses implement security awareness training and managed IT support that reinforce these habits year-round—not just during tax season.
The Bigger Picture: Cybersecurity Is About Timing
Tax season attacks aren’t especially clever.
They’re well-timed.
They rely on:
- Rushed approvals
- Financial pressure
- Email overload
- Assumptions
Cybersecurity isn’t just about firewalls and antivirus.
It’s about managing human behavior during high-risk seasons.
And March is one of the highest-risk months of the year for phishing and business email compromise.
A Quick Busy-Season Cybersecurity Sanity Check
Your business may already have:
- Multi-factor authentication (MFA)
- Email filtering and spam protection
- Endpoint security
- Backup and disaster recovery
- Vendor verification processes
If so, that’s excellent.
But if tax season pushes your team into reactive mode, or you’re unsure how urgent requests are handled under pressure, it may be worth a quick sanity check.
No overhaul.
No scare tactics.
No pressure.
Just clarity.
