Why Phishing Attacks Increase During Tax Season
March is one of the busiest months of the year for accountants, bookkeepers, and finance teams.
Deadlines are approaching. Documents are being exchanged rapidly. Emails move quickly between businesses, accountants, payroll providers, and vendors.
While this busy season is expected for financial professionals, it also attracts the attention of cybercriminals.
Security researchers consistently see a surge in phishing attacks during tax season. Many reports show roughly a 25 to 30 percent increase in tax related phishing emails compared to quieter months.
These messages are not dramatic or obvious scams. They are designed to look like routine business communication during one of the busiest times of the year.
For hackers, timing is everything.
Why Cybercriminals Target Tax Season
Most people assume attackers are targeting accounting firms directly.
In reality, they often target the entire ecosystem around them.
During tax season, businesses are:
• Sending financial documents frequently
• Communicating with accountants and payroll providers
• Handling sensitive employee information
• Working under tight deadlines
The increased pace creates a perfect environment for mistakes.
When people are rushed, they are more likely to click links quickly, open attachments without verifying them, or respond to urgent requests without confirming the sender.
Cybercriminals take advantage of that pressure.
What Tax Season Phishing Attacks Look Like
Modern phishing attacks are rarely obvious.
Instead of suspicious messages filled with spelling errors, most phishing emails today look like ordinary business communication.
Examples include:
• An email appearing to come from your accountant asking you to resend tax forms
• A message from a vendor claiming their payment details have changed
• A document signature request for tax paperwork
• A message appearing to come from an executive requesting urgent help
Each message looks routine and believable. That is why these attacks succeed.
Attackers do not rely on dramatic scams. They rely on emails that blend into the normal flow of business communication.
Why Busy Employees Are More Vulnerable
Falling for a phishing email does not mean someone was careless.
It usually means they were busy.
When inboxes are full and deadlines are approaching, people tend to skim emails instead of reading them carefully. They assume messages are legitimate and respond quickly to keep work moving.
Cybercriminals understand this behavior.
Their emails are designed to appear urgent and routine at the same time. They only need one moment of distraction to succeed.
During tax season, many organizations experience exactly that environment.
Four Simple Ways to Reduce Phishing Risk
The good news is that preventing many tax season phishing attacks does not require complex tools or expensive systems.
Small habits can dramatically reduce risk.
1. Verify payment changes by phone
If an email says a vendor has changed their banking information, never rely on the email alone.
Call a known contact using a trusted phone number to confirm the change.
This one habit prevents many costly financial scams.
2. Slow down requests for sensitive information
Requests for tax documents, payroll files, or financial data should always be verified before sending them.
Urgent requests are often used by attackers to pressure people into acting quickly.
Take a moment to confirm the request before responding.
3. Confirm urgent messages through another channel
If an email claims something is urgent, verify the request using another method.
A quick phone call, internal message, or text can confirm whether the request is legitimate.
Real urgency can survive a brief verification. Fake urgency cannot.
4. Remind your team about tax season scams
A quick reminder can make a big difference.
Let your team know that phishing attempts often increase during tax season and that it is acceptable to slow down and double check anything that looks unusual.
Giving employees permission to pause and verify requests can prevent major problems.
The Takeaway
Tax season is already stressful for most businesses.
Cybercriminals know this and take advantage of the pressure.
Most tax season phishing attacks are not especially sophisticated. They are simply timed to arrive when employees are moving quickly and making fast decisions.
You do not need to overhaul your entire security strategy to reduce risk.
Often, slowing down and verifying requests during busy periods is enough to stop many attacks before they start.
