2.  Security Summit: The IRS reminds tax pros to guard against identity theft as summer series wraps up

The IRS and its Security Summit partners closed out the fifth and final week of the summer 2025 “Protect Your Clients; Protect Yourself” awareness series this week with a reminder to stay vigilant and strengthen safeguards to protect against identity theft. In the first half of the year there were nearly 300 data breaches reported impacting affecting as many as 250,000 clients.

Tax pros should watch for client red flags such as:

• IRS Online Account created or accessed without consent
• Unrequested tax transcripts
• Incorrect IRS balance-due statements or notices
• Refunds without filing a tax return

The Security Summit, a public-private partnership of tax professionals, industry partners, state tax agencies and the IRS, has worked since 2015 to protect the tax system from identity theft and fraud.
