The FTC Safeguards Rule for Tax and Accounting Firms: The Written Plan, MFA and the 30-Day Breach Notice

By

Tax preparers, many accounting firms, mortgage brokers and non-SEC-registered advisers are "financial institutions" under the FTC's Safeguards Rule. It requires a written information security program with nine elements, MFA for anyone accessing customer information, and since May 2024 a notice to the FTC within 30 days of a breach affecting 500 or more people. What is required and a practical setup for a small firm.

MFA

The FTC's definition of a financial institution is wider than most firms expect. The guidance lists tax preparation firms, mortgage lenders and brokers, finance companies, collection agencies, credit counsellors and investment advisers not registered with the SEC, among others, and says "what matters are the types of activities your business undertakes".

The nine elements

  1. A qualified individual who oversees the program (can be an outside provider, with someone in the firm supervising).

  2. A written risk assessment, updated periodically.

  3. Safeguards: access controls, encryption of customer information, MFA for anyone accessing customer information, secure disposal within two years of last use unless needed, and change management.

  4. Testing: continuous monitoring, or annual penetration tests plus vulnerability assessments every six months.

  5. Staff security training.

  6. Oversight of service providers.

  7. Keeping the program current as the business changes.

  8. A written incident response plan.

  9. An annual written report to the board or owners.

Firms holding information on fewer than 5,000 consumers are exempt from some of these, including the written risk assessment, the incident response plan and the annual report. MFA and encryption still apply.

The breach notice

Since May 2024, a firm must notify the FTC through its online form as soon as possible, and no later than 30 days after discovery, when unencrypted information of at least 500 consumers is acquired without authorization. State breach laws and IRS reporting for tax professionals apply in addition.
