What insurance do tax attorneys and CPAs at law firms need?

Tax practice creates distinct malpractice exposures because errors in tax advice or preparation can result in quantifiable financial harm including additional taxes, penalties, interest, and lost deductions or credits. These damages are often easier for claimants to prove than in other practice areas because the IRS and state tax authorities produce definitive assessments showing the exact amount of additional liability caused by the alleged error.

Common tax-related malpractice claims include incorrect advice on the tax treatment of transactions, missed filing deadlines for returns or elections, failure to advise on available tax benefits or planning opportunities, errors in structuring transactions for tax efficiency, and failure to anticipate changes in tax law that affect a client's position. Tax opinions that prove incorrect can also generate claims, particularly when clients relied on the opinion to take aggressive positions that are later challenged by the IRS.

If your firm employs CPAs or accountants who provide accounting, auditing, or tax preparation services in addition to legal representation, confirm that your malpractice policy covers these activities. Some legal malpractice policies exclude claims arising from accounting or auditing services, and a separate accountants professional liability policy may be required. Alternatively, some carriers offer endorsements that extend legal malpractice coverage to include accounting professional services performed by the firm's licensed CPAs.

Tax attorneys who represent clients before the IRS or state tax agencies should also confirm that their policy covers administrative proceedings, not just court litigation. Representation in IRS audits, appeals, and collection matters is professional legal work that generates malpractice exposure, and your policy should explicitly cover claims arising from these services.
