The sources of obligation
Several overlapping sources shape how a US tax and accounting practice handles client information. The ones most practices hear about are these:
- Professional ethics. The AICPA Code of Professional Conduct includes a confidential client information rule for members, and state boards of accountancy have their own rules for licensees.
- Tax return information. Federal law restricts how tax return preparers may use and disclose tax return information. The rules have specific consent requirements, which is a topic for your attorney.
- The FTC Safeguards Rule. The rule applies to tax preparers and requires a written information security program with safeguards for customer information.
- IRS guidance. The IRS publishes guidance for tax professionals on safeguarding taxpayer data, including practical security steps.
- State law. Every state has data breach notification rules, and some states have broader privacy laws that may reach a firm depending on its size and clients.
The details of each, including which apply to you and what they require, are matters to confirm with your attorney. What they have in common is simple: know where client information is, control who can reach it, and be able to show what you did.
