Cybersecurity & Tax Season: How to Keep Your Financial Data Safe from Cyber Threats

Introduction

Tax season, which runs from January through April, is already stressful enough, between gathering financial documents, crunching numbers, and ensuring every detail is accurate, the pressure is real. And let’s be honest, the fear of making a mistake that could lead to an audit (or worse…prison) only adds to the anxiety. Unfortunately, cybercriminals know this all too well, making tax season one of the peak times for cyber fraud and scams.

Hackers take advantage of the rush and stress, using tactics like IRS impersonation scams, phishing emails from fake tax services, and even attempts to intercept tax refunds. With financial data in high demand, they know individuals and businesses are more vulnerable during this time.

In this blog, we’ll break down the biggest cybersecurity threats during tax season, share best practices to keep your financial data secure, and explore how an IT provider like Charles IT can help protect your business from tax-related cyber threats.

The Biggest Cyber Threats During Tax Season

Now that it’s clear cybercriminals ramp up their attacks during tax season, let’s break down how they’re actually doing it. Here are the top three biggest cyber threats you need to watch out for:

1. Phishing Scams Targeting Taxpayers and Businesses

Tax season is prime time for phishing scams because cybercriminals know that most people are busy, stressed, and in a rush to meet deadlines. This distraction makes them less vigilant in spotting red flags in emails, texts, and even phone calls. Attackers often impersonate trusted sources like the IRS, tax preparation services (H&R Block, TurboTax), or financial institutions, sending fraudulent emails designed to trick recipients into clicking malicious links, downloading malware, or providing personal information. These emails might claim there’s an issue with your tax return, request additional verification, or even promise an unexpected refund, basically anything to get you to engage.

To make their scams more convincing, cybercriminals use spoofed email addresses, official-looking logos, and urgent language to pressure victims into responding quickly. If successful, these attacks can lead to identity theft, stolen tax refunds, and unauthorized access to sensitive financial data.

2. Ransomware Attacks on Financial Institutions

Hackers don’t just target individuals during tax season, they go after financial institutions and tax preparation firms as well. These organizations handle massive amounts of sensitive data and financial transactions during this time, making them prime ransomware targets.

A well-timed ransomware attack can lock down entire systems, preventing tax professionals, banks, and even payroll departments from accessing critical files. This disruption can delay tax filings, block people from accessing their funds, and create chaos for businesses and individuals alike. Cybercriminals know that during such a high-stakes season, companies may be more likely to pay the ransom to restore operations quickly.

3. Business Email Compromise (BEC) and Tax Form Fraud

During tax season, sensitive tax forms like W-2s, 1099s, and other financial documents are frequently sent via email, making them an easy target for cybercriminals. Attackers use Business Email Compromise (BEC) tactics to intercept these emails, often by spoofing or hacking into company accounts to trick employees into sending tax forms directly to them.

In some cases, cybercriminals impersonate HR representatives, accountants, or executives, requesting tax documents or payroll information under the guise of company business. Employees, believing they are complying with a legitimate request, unknowingly hand over Social Security numbers, bank account details, and other sensitive data, which is all information that can be used for identity theft, fraudulent tax filings, or financial fraud.

Best Practices to Secure Your Financial Data

Protecting yourself and your business from cyber threats during tax season requires a proactive approach to cybersecurity. Fortunately, implementing a few key best practices can go a long way in safeguarding your financial data. Here’s what you should do:

Implement Multi-Factor Authentication (MFA)

Multi-Factor Authentication (MFA) adds an extra layer of security by requiring a secondary form of verification beyond just a password. This could be a one-time code sent to your phone, an authentication app, or even a biometric challenge like a fingerprint scan.

Even if a cybercriminal manages to steal your password, they won’t be able to access your account without the second authentication factor. For tax season, enable MFA on all relevant accounts, including tax preparation software, your IRS account, financial institution logins, and payroll systems. This significantly reduces the risk of unauthorized access to your sensitive financial data.

Use Encrypted Email and Secure Document-Sharing Platforms

Tax documents contain some of the most sensitive personal information, including Social Security numbers, income details, and bank account information, making them a prime target for cybercriminals. Instead of sending these documents as regular email attachments, use encrypted email services or secure file-sharing portals provided by your tax preparer. These tools protect your data by ensuring that only the intended recipient can access it.

If you need to send physical copies of tax documents, use a trusted courier service with tracking options instead of standard mail. This helps reduce the risk of interception and identity theft.

Keep Software and Systems Updated to Prevent Vulnerabilities

Outdated software is one of the easiest ways for hackers to exploit security weaknesses. Cybercriminals are constantly developing new attack methods, and software updates include critical security patches to protect against emerging threats.

Before tax season gets into full swing, ensure that:

• Your operating system, tax preparation software, and financial apps are fully updated.
• Your antivirus and anti-malware software are active and running the latest version.
• Any browser extensions or add-ons used for financial transactions are secure and up to date.

Regularly updating your systems helps close security gaps and prevents cybercriminals from exploiting outdated technology to gain access to your financial data.

By implementing these best practices, you can significantly reduce the risk of falling victim to cyber threats this tax season.

How an IT Provider Can Help

While implementing cybersecurity best practices is essential during tax season, partnering with a trusted IT provider like Charles IT can take your security to the next level. With advanced security solutions, employee training, and incident response planning, an IT provider helps ensure that your financial data remains protected from cyber threats. Here’s how:

Implementing Managed Security Services for Proactive Protection

Cyber threats ramp up during tax season, and so should your security strategy. An IT provider offers managed security services that provide round-the-clock protection for your business, helping to detect and stop cyber threats before they cause damage. These include:

• External Vulnerability Scanning: Identifies and alerts you to potential weaknesses in your network to prevent data breaches.
  
  
• Endpoint Encryption: Ensures sensitive financial data is encrypted, blocking unauthorized users from accessing confidential information.
  
  
• Security Information & Event Management (SIEM): Provides 24/7 monitoring of your IT infrastructure, alerting you to suspicious activity in real time.
  
  
• Access Monitoring: Prevents unauthorized access and detects suspicious login attempts with real-time security alerts.
  
  
• Dark Web Monitoring: Alerts you if your credentials are found on the dark web, allowing you to take immediate action.
  
  
• Managed Detection & Response (MDR): Uses advanced threat intelligence, analysis, and proactive threat hunting to stop cyberattacks before they escalate.

By leveraging these proactive security measures, businesses can reduce the risk of cyberattacks and keep their financial data secure during tax season and beyond.

Conducting Employee Security Awareness Training

Your employees are your first line of defense against cyber threats. Without proper training, they may unknowingly fall for phishing scams or social engineering attacks, especially during tax season, when these threats are at an all-time high.

An IT provider ensures that all employees, from new hires to executives, are well-equipped to recognize and prevent cyber threats through ongoing security awareness training. Key components of this training include:

• Email Phishing Testing: Simulated phishing attacks to teach employees how to recognize and avoid scams.
  
  
• USB Phishing Assessments: Tests employee awareness regarding the risks of inserting unknown USB devices into company computers.
  
  
• Incident Reporting Protocols: Establishes clear procedures for reporting suspicious activity to reduce the impact of security incidents.

With structured training programs, your team becomes a human firewall, adding an extra layer of security beyond what automated systems can provide.

Enacting Incident Response Planning for Quick Recovery

Even with strong security measures in place, no system is 100% immune to cyber threats. That’s why having a well-documented incident response plan is crucial.

An IT provider helps businesses develop a comprehensive incident response strategy to minimize downtime and financial losses in case of a security breach. This includes:

• Backup and Disaster Recovery (BDR): Regular, secure backups of sensitive tax and financial data, ensuring quick recovery after an attack.
  
  
• Rapid Response Protocols: Step-by-step guidelines for mitigating cybersecurity incidents, so your team knows exactly what to do if a breach occurs.
  
  
• Business Continuity Planning: Ensures your business operations remain intact, even in the face of a cyberattack.

By planning for worst-case scenarios, your business can avoid disruptions, data loss, and financial setbacks, keeping everything running smoothly during tax season.
