Why Accounting Firms Need Cyber Insurance
Accounting firms are among the most targeted businesses for cyberattacks. The IRS reported a 300% increase in phishing attacks targeting tax professionals since 2023.
Top cyber threats for accountants:
- Tax-related identity theft — stolen returns filed fraudulently
- Phishing / spear phishing — targeting CPAs during busy season
- Ransomware — locking client files during tax deadlines
- Client portal breaches — unauthorized access to shared documents
- Business email compromise — fake invoices or wire instructions

Tax Season Risks & Preparedness
Tax season (January–April) is when accounting firms face their highest cyber risk. Staff working longer hours are more likely to click phishing emails, and attackers know the deadline pressure creates urgency.
Pre-tax season checklist:
- Verify cyber insurance is active and limits are adequate
- Conduct phishing simulation training for all staff
- Enable MFA on all client portals and email accounts
- Test backup and recovery procedures
- Review and update your Written Information Security Plan (WISP)
IRS Safeguards Rule Compliance
The IRS requires all tax preparers to comply with the FTC Safeguards Rule under GLBA:
- Designate a security coordinator responsible for your WISP
- Conduct regular risk assessments of client data handling
- Implement access controls — limit who can view client data
- Encrypt data in transit and at rest
- Have an incident response plan
Cyber insurance helps cover costs when compliance fails — regulatory investigation defense ($50K–$200K+ in legal fees), remediation costs, and client notification requirements.

Real Claims Examples
Phishing Attack During Tax Season — $175,000 Loss: A 6-person CPA firm received a phishing email disguised as an IRS e-Services notification. An employee clicked the link, exposing credentials that gave attackers access to 2,300 client tax returns.
Ransomware 3 Weeks Before April 15 — $280,000 Total: Ransomware encrypted all client files at a mid-size firm. The firm paid a $60K ransom and spent $120K on recovery, $50K on business interruption, and $50K on security upgrades.
Client Lawsuit After Data Breach — $95,000 Settlement: A bookkeeper's laptop was stolen containing unencrypted client data for 400 businesses. Three clients sued for negligence.
Frequently Asked Questions
Does my professional liability / E&O policy cover cyber incidents?
Usually not. Most CPA E&O policies exclude cyber events. You need a standalone cyber policy or a bundled Cyber + E&O package.
Is cyber insurance required for CPAs?
While not legally mandated, the IRS Safeguards Rule requires adequate data protection. Many professional associations strongly recommend cyber coverage.
What's the biggest cyber risk for accountants?
Phishing and business email compromise account for over 70% of cyber incidents at accounting firms.
Should I get cyber insurance even as a solo CPA?
Yes. Solo practitioners are actually more vulnerable because they lack dedicated IT security staff. A basic policy starts around $800/year.

Why Use a Brokerage Platform Instead of Buying Direct?
When a carrier offers instant quote-and-bind on their website, it's convenient — but you're only seeing one carrier's rates. A brokerage platform like Insura changes that equation:
- One application, multiple quotes. Fill out one form and get compared across 10+ A-rated carriers including Hartford, Chubb, Hiscox, and more. No need to re-enter your business info on five different websites.
- The price is the same — or lower. Carriers pay the broker's commission directly. Your premium is identical to what you'd pay buying direct, and often lower because a broker can find a carrier that prices your specific risk more competitively.
- We work for you, not the carrier. A direct carrier's website is designed to sell you their policy. A brokerage platform is designed to find you the best policy — we have no incentive to push one carrier over another.
- Automated comparison shopping, year after year. When your policy renews, a brokerage platform automatically re-shops your coverage across carriers to make sure you're still getting the best rate. Buy direct, and you're locked into one carrier's renewal pricing with no leverage.
- Licensed experts when you need them. Have a coverage question or need help with a claim? You get access to real brokers — not a carrier's customer service line reading from a script.
