Mercadien PC Certified Public Accountants recently reported a data security incident to the Texas Attorney General on October 13, 2026. This incident, which the firm identified on November 7, 2025, involved unauthorized access to portions of its network or system environment. Given Mercadien PC's role in handling extensive financial data, this breach indicates that personal information entrusted to the firm may have been compromised.
The types of personal information reported as exposed in this incident include Full Name, Social Security Number, Date of Birth, Tax Return Information, Wage and Compensation Information, Direct Deposit Account Details, Financial Account Number, and Home Address. This combination of data is highly sensitive, providing a comprehensive profile that can be exploited for various forms of identity theft and financial crimes.
Attackers often use such deeply personal and financial data to commit fraud. This can range from filing fraudulent tax returns and opening new credit accounts in victims' names to intercepting direct deposits or attempting to empty financial accounts. Unlike other data, foundational financial details like Social Security Numbers and tax records are permanent, potentially leading to long-term exposure and recurring threats of exploitation.

What to do if you were affected
Based on the categories of information reported in this filing, these steps can help limit the risk of identity theft and fraud.
Freeze your credit
Place a free credit freeze with Equifax, Experian, and TransUnion. A freeze blocks new accounts from being opened in your name and can be lifted anytime.
Guard against tax fraud
File your tax return as early as possible and consider requesting an IRS Identity Protection PIN so no one can file a fraudulent return in your name.

Review bank and card statements for unfamiliar activity and turn on transaction alerts. Report anything you don't recognize to your bank right away.

Keep your notification letter
