Tax season is when attackers go after small businesses hardest, and running Macs does not put you out of reach. Hackers target whatever system is exposed, regardless of platform. The fix is the same every year: train your team, lock down how you share files, turn on multifactor authentication, and confirm payment requests by a second channel before any money moves.
While you and your staff are buried in financial documents, returns, and deadlines, that distraction is exactly what scammers count on. Here is why this stretch of the year is risky for a Mac business and what to do about it.
Why attackers circle during tax season
- You move more sensitive data. Tax work means passing financial and personal records around, inside your company and out to accountants or payroll providers. Every handoff is a chance for someone to slip in a fake email or a malicious link. Your MacBooks and iMacs are not immune to that.
- Deadline pressure makes people careless. When everyone is rushing, nobody stops to check the sender, the link, or the attachment. That is how phishing and malware get through, Macs included.
- Email volume spikes. Forms, payment requests, compliance notices: your inbox fills up fast. Attackers hide their phishing messages in that flood, dressed up to look like they came from a source you trust.
- Tax scams are everywhere right now. Hackers pose as the IRS or a tax prep service to get you to share confidential information or send a fraudulent payment.
The threats to watch for
- Phishing emails: fake messages claiming to be the IRS, your accountant, or a tax service, asking for sensitive information or pushing you toward a malicious link.
- Fake invoices and payment requests: phony bills or payment demands meant to route your money to an account the scammer controls.
- Ransomware: attackers encrypt your financial data and demand payment to unlock it, which can shut you out of your Macs entirely.
- Social engineering: someone calls or emails pretending to be your accountant, payroll provider, or a trusted contact to talk an employee out of sensitive information.
How to protect your Mac business
- Train your team. Your people are the first line of defense, so make sure they know what current scams look like on a Mac. Teach them to:
- Check who actually sent an email before opening an attachment or clicking a link.
- Treat urgent payment requests and surprise account changes as suspect until proven otherwise.
- Report anything that looks off to IT right away.
- Stop sending sensitive files over plain email. Keep tax data encrypted in transit. Use a secure portal or an encrypted file-sharing tool: Apple's AirDrop (end-to-end encrypted) or a service like Box or Dropbox, not a regular email attachment.
- Turn on multifactor authentication. Require MFA on financial systems, email, and anything you touch for tax work. A stolen password alone should not get anyone in, and that matters most when staff work remotely on personal Macs. Apple's built-in two-factor authentication for iCloud, macOS, and apps like Safari covers a lot of this for you.
- If MFA is not on yet, switch it on now for every financial or sensitive business account.
- Run a security audit before the crunch. Have your IT provider check the Mac-specific basics:
- Every Mac is on the latest macOS update.
- Network endpoints and connected devices are locked down, especially personal Macs being used for work.
- Backups actually work. Confirm that Time Machine or your cloud backup is running and that the files are encrypted. A backup you have never tested is a guess, not a safety net.
- Verify every payment request. Before money moves, double-check the request, particularly large sums or unfamiliar accounts. If anything feels off, confirm it through a second channel, a phone call or a quick FaceTime, with someone you already know.
Don't let hackers cash in this tax season
Running Macs does not make tax season open season for hackers. Train your team, tighten how you share files and sign in, and verify the money before it leaves. Do that and you close the gaps scammers count on.
