DC Professional Tax Service reported a data security incident to the California Attorney General on February 26, 2026, with the breach itself dated February 24, 2026. The official notification letter filed with the state is a scanned document, so the specific text describing how the breach happened could not be extracted or read. Because of this, the exact method of attack — whether it involved hacking, a phishing scheme, an unauthorized insider, or something else — is not confirmed and is listed here as unknown rather than guessed at.
The filing does not state how many individuals were affected or specify their location, so the full scope of who received a letter isn’t available from the readable portion of this filing. If you received a notification letter directly from DC Professional Tax Service, that letter is the most reliable source for details specific to your situation, including what data of yours may have been involved.
What information was exposed?
- The specific data types involved in this breach were not disclosed in the readable version of the filing.
- Tax preparation businesses like this one typically handle highly sensitive information, which can include Social Security numbers, tax identification numbers, income and financial account details, and government-issued ID numbers — but this article cannot confirm which, if any, of these were actually exposed in this specific incident.
- If you have a direct relationship with this company, check your notification letter or contact the company directly for a list of exactly what information of yours was involved.
What should you do now?
- Request a copy of your notification letter (or re-read it closely) to see if it lists the specific data types involved — this will help you decide which of the steps below matter most for you.
- Given that tax preparers commonly store Social Security numbers and financial account details, consider placing a fraud alert or credit freeze with the three major credit bureaus (Equifax, Experian, and TransUnion) as a precaution.
- Watch your bank and credit card statements closely for unfamiliar charges, and monitor your credit reports for new accounts you didn’t open.
- Be alert for tax-related fraud specifically, such as unexpected IRS notices about returns you didn’t file, since tax preparers hold information that can be misused this way.
- Consider signing up for a service like Aura or LifeLock, which can alert you if your personal information appears somewhere it shouldn’t.
- Be cautious of unexpected calls, texts, or emails claiming to be from DC Professional Tax Service or the IRS asking you to confirm personal details — verify independently before responding.
