During tax season, everyone is under pressure, feeling the urgency around filing deadlines and refunds. However, while you’re distracted and overwhelmed, it’s the perfect opportunity for cybercriminals to extract sensitive information or cash.
Recent research shows that scammers are using AI to craft convincing phishing messages and calls that impersonate revenue authorities, with a large share of people reporting bogus tax-related contact attempts and financial losses from fake tax refund communications.
This means that, during tax season, you need to ensure your cybersecurity is up to scratch.
Understand The Threat Spike This Season
Phishing and impersonation attempts increase sharply as tax deadlines approach. Criminals send messages that look like official tax system alerts, complete with familiar logos and urgent language designed to get you to act quickly. These scams often carry links or attachments that steal login credentials or install malware once opened.
Local reports indicate that phishing accounts for a large share of incidents reported by organisations, with a year-on-year rise as tax season opened in 2025.
Strengthen Authentication and Identity Checks
To beef up your security against scammers, try the following approach:
- Enforce strong access controls across all accounts that handle financial or personal data.
- Implement multi-factor authentication to limit credential attacks.
- Confirm the identity of anyone requesting sensitive information with direct, verified contact channels.
Systems that flag unusual login patterns or repeated failed access attempts can alert your team before an attack can progress further.
Monitor AI-Enabled and Voice-Based Scams
AI has made scams more personalised, with phishing texts and calls that mimic official language and even voice prompts from trusted institutions.
Therefore, set up threat monitoring systems that scan for unusual inbound communications containing suspicious links or domains. Training your team to spot anomalies in tone and sender details will reinforce these technical measures.
Train Your People With Regular Awareness
Education about the most current scam tactics will enhance your security significantly. Work with your managed security team to run sessions that highlight typical phishing styles seen during tax season, such as spoofed e-filing notifications, fake refund offers and bogus compliance alerts.
Repeated training year on year will build instinctive scrutiny of unsolicited messages before any links are clicked.
Build Vendor-Neutral Security Policies
Your security policy should address how to handle email attachments, links and verification requests in a clear and well-documented way. It should also include incident reporting procedures and escalation paths so that suspicious activity can be logged and reviewed rapidly.
Importantly, ensure there is centralised monitoring and periodic reviews of policy effectiveness.
Use Layered Technical Controls
On a technical level, deploy filtering and detection tools that look at email headers, URLs and attachment behaviour to detect potential threats early. This kind of real-time analysis can block malicious traffic before it even hits inboxes.
When you combine endpoint protection with network monitoring, you can spot threats that might otherwise bypass a single control.

Frequently Asked Questions
- Why do cyber attacks increase during tax season?
Cyber attacks increase during tax season because people are under pressure and more likely to respond quickly to urgent messages. Criminals exploit this by sending phishing emails and fake refund notifications to steal sensitive data.
- What are common tax season phishing scams?
Common scams include fake tax refund messages, spoofed e filing alerts, fraudulent compliance notices and emails pretending to be from revenue authorities asking for personal or financial details.
- How can businesses prevent phishing attacks during tax season?
Businesses can prevent phishing attacks by implementing multi factor authentication, using email filtering tools, verifying requests through trusted channels and training employees to identify suspicious messages.
- What role does AI play in modern cyber scams?
AI enables cybercriminals to create highly personalised phishing messages and voice scams that mimic trusted institutions. This makes scams more convincing and harder to detect without proper awareness and monitoring.
- What is multi factor authentication and why is it important?
Multi factor authentication adds an extra layer of security by requiring more than one verification step. It reduces the risk of unauthorised access even if login credentials are compromised.
- How can employees identify suspicious emails or messages?
Employees should check sender details, look for unusual language or urgency, avoid clicking unknown links and verify requests directly with the organisation before taking action.
- What technical controls help protect against cyber threats?
Effective controls include email filtering systems, endpoint protection, network monitoring and tools that analyse links, attachments and login behaviour to detect threats early.
- Why is cybersecurity training important during tax season?
Regular training helps employees recognise evolving scam tactics and respond correctly. This reduces the likelihood of human error, which is one of the main causes of security breaches.
