What gets asked for on the day

What reviewers sample about these documents and the people they cover.

PTIN renewal question

Form W-12 line 11 asks each preparer to confirm awareness of the legal duty to create and maintain a WISP; a box must be checked to complete the form.

The plan itself

In an FTC inquiry, expect a request for the written plan, its last review date and the named Qualified Individual.

Staff acknowledgment

IRS guidance treats signed, dated employee acknowledgments kept on file as the documentation trail for training and policy understanding.

Data loss response

After a data theft, IRS guidance has preparers report the loss to the IRS and states; the plan's breach procedures show who does what.

Questions

Does a sole practitioner need a WISP?

Publication 5708 states that tax and accounting professionals are financial institutions under the GLBA and Safeguards Rule regardless of size. It also notes a sole practitioner can use a shorter plan scaled to the practice.

What does the PTIN renewal ask?

Form W-12 (Rev. October 2025), line 11, asks the preparer to confirm awareness that paid preparers are required by law to create and maintain a WISP, and points to Publications 5708 and 4557. The online renewal carries the same question.

How often should the WISP be reviewed?

The IRS sample template carries a last modified or reviewed date and calls for review and update at least annually. The Safeguards Rule also expects the program to be adjusted after testing results or material changes.

What do practices with fewer than 5,000 clients skip?

Under 16 CFR 314.6, institutions holding information on fewer than 5,000 consumers are exempt from the written risk assessment, written incident response plan, annual board report and continuous monitoring or testing requirement. The written plan, Qualified Individual, safeguards and staff training still apply.

Do e-file providers have additional standards?

Publication 4557 notes that online providers must also follow the six security and privacy standards in Publication 1345 for authorized IRS e-file providers. Those sit alongside the WISP.
