Cyber insurance for CPA firms — before the 2026 renewal squeeze

Client tax data, payroll files, and portal credentials are prime ransomware targets. Underwriters now expect MFA and backup proof on every return season.

  • Client tax data and W-2 files are a top ransomware target — one encrypted share drive can halt an entire practice.
  • Carriers increasingly ask for MFA on all tax-software and email logins, not just “the partners.”
  • IRS Pub. 4557 and state breach rules expect a written security plan — checkboxes on the app are not enough.

Regulatory context (not legal advice)

  • IRS Publication 4557 (Safeguarding Taxpayer Data)
  • FTC Safeguards Rule (where applicable to financial institutions you serve)
  • State breach-notification laws (PA and surrounding states)

KJ Digital Solutions is a risk-reduction consultancy — not an insurer, broker, or guarantor of coverage, premiums, or claim payouts. The carrier determines coverage; you remain responsible for maintaining controls for the policy term.

From declined files to bound policies

  • “This got our law firm from declined to bound in 10 days. The packet was what the underwriter actually asked for.”

    Elena V., Managing partner, Harbor Lane Law

  • “We stopped emailing screenshots. MFA and backup evidence were verified before the broker even called the carrier.”

    Priya N., Practice manager, North Clinic Group

  • “I run this for twelve clients from one dashboard. Renewal prep used to be a spreadsheet. Now it is a packet.”

    Chris A., Owner, Alder MSP

  • “The readiness score told us backups were the gap. We fixed them and the remarket came back with a quote.”
