Department of Revenue Data Breach Notice (Massachusetts Attorney General)

The Massachusetts Department of Revenue has notified one resident that their Social Security number was exposed in a data breach. A filing with the Massachusetts Office of Consumer Affairs dated August 04, 2026 lists Social Security numbers as the information involved.

Your Social Security Number Cannot Be Changed

If you received the letter, this exposure creates a permanent risk. Unlike a credit card or password, a Social Security number stays with you for life. It cannot be reissued on request the way other identifiers can. That single nine-digit string remains a key that can be used to open accounts, file tax returns in your name, or claim government benefits years from now.

The filing does not list any other categories of information. No passwords were exposed. No financial account numbers appear in the record. The only permanent identifier named is the Social Security number itself.

What This Exposure Enables

An exposed Social Security number combined with basic personal details such as name and date of birth allows identity thieves to commit tax fraud, apply for loans, or create synthetic identities. Because the number never expires, the risk does not fade with time. Credit monitoring can alert you to new accounts opened in your name, but it cannot prevent someone from filing a fraudulent tax return before you do each year.
