Commonwealth of Massachusetts Department of Revenue State was the subject of a data breach notification filed with the MA Attorney General. The AG filing was recorded on June 26, 2025.
From the AG filing description
The Commonwealth of Massachusetts Department of Revenue State serves as the primary tax administration and revenue collection agency for the Commonwealth, overseeing state income taxes, corporate excise taxes, sales and use taxes, and municipal finance oversight. Because of its governmental and financial regulatory role, the Department of Revenue routinely collects, processes, and maintains an extraordinary volume of highly sensitive personal and financial documentation from virtually every resident taxpayer, business owner, and employer operating within the state. This expansive repository of state records is essential for executing government operations, enforcing tax compliance, and distributing municipal aid, making the agency a central hub of critical citizen data. In 2025, the Commonwealth of Massachusetts Department of Revenue State reported a major data security incident to the Massachusetts Attorney General, raising significant concerns among taxpayers and legal experts alike. While public disclosures continue to evolve, cybersecurity incidents impacting state revenue agencies typically involve sophisticated cyberattacks, unauthorized intrusions into state mainframe databases, or vulnerabilities within third-party vendor platforms used for tax processing and electronic filing portals. Such breaches often exploit legacy infrastructure or zero-day vulnerabilities, allowing malicious actors to bypass perimeter defenses and dwell undetected within internal networks where vast troves of citizen records are stored. The exposure resulting from a breach of a state revenue department involves exceptionally high-risk categories of personal identifiable information and financial data. Exposed records typically include full legal names, Social Security Numbers, dates of birth, home addresses, banking and direct deposit details, corporate identification numbers, and detailed state and federal tax return information containing wage and income histories. The compromise of this specific combination of data creates an immediate and severe risk of state and federal tax refund fraud, synthetic identity theft, unauthorized bank account access, and long-term financial extortion. Because tax data provides cybercriminals with a comprehensive profile of an individual's financial life, victims face a prolonged and difficult journey to secure their credit and financial standing. As a state governmental agency handling sensitive citizen data, the Commonwealth of Massachusetts Department of Revenue State is bound by strict statutory and regulatory frameworks designed to protect public information, including the Massachusetts Data Privacy Law (M.G.L. c. 93H) and state information security regulations (201 CMR 17.00). These legal frameworks mandate the implementation of comprehensive administrative, physical, and technical safeguards, including robust encryption standards, multi-factor authentication, regular vulnerability assessments, and strict access controls. The occurrence of a widespread data breach strongly suggests potential failures in upholding these mandatory security standards, leaving vulnerable government systems exposed to preventable cyber threats. Receiving a data breach notification letter from the Commonwealth of Massachusetts Department of Revenue State is a formal acknowledgment that your private information was compromised due to institutional security failures. Legally, this notification establishes the foundation for affected individuals to participate in a class action lawsuit aimed at holding the agency accountable, securing mandatory credit monitoring services, and recovering compensation for mitigation efforts and damages. Under applicable state laws, victims do not need to prove actual financial fraud or identity theft to pursue legal remedies; the increased, imminent risk of future harm is sufficient. Our firm evaluates these cases on a strict contingency fee basis, meaning you pay nothing out of pocket and we only collect a fee if we successfully recover compensation on your behalf.
Under the Massachusetts Data Security Law (201 CMR 17.00), you may have a legal claim against Commonwealth of Massachusetts Department of Revenue State if any of the following apply:
Based on the data types reported in this filing:
Your SSN is the master key to your identity. Once exposed, criminals can open new lines of credit, take out loans, or file taxes in your name.
Combined with a name and other leaked data, date of birth helps criminals pass identity verification questions at banks and government agencies.
Common categories of compensation in data breach class actions
Courts recognize that the time spent monitoring accounts, placing credit freezes, and dealing with the aftermath of a breach has real economic value. This category of damages is recoverable even without direct financial loss.
Professional credit monitoring services cost $10–$40 per month. Identity theft restoration services, if needed, can cost hundreds of hours and thousands of dollars. Courts have awarded these costs as direct damages in SSN breach cases.
Direct financial losses resulting from the breach — unauthorized charges, fraudulent transfers, or fees incurred through fraud — are recoverable as compensatory damages. Banks may reverse some charges; a class action recovers the remainder and associated costs.
Several state data breach laws provide for statutory minimum damages — fixed amounts recoverable per affected individual regardless of actual loss. These provisions exist specifically to make legal action viable for victims who have not yet experienced direct harm.
Note: an attorney general breach filing does not by itself establish a settlement fund, a payment amount, or a claim deadline. If an official settlement notice is later issued, rely on that notice for payment details and deadlines.
No. Under Massachusetts Data Security Law (201 CMR 17.00) and federal law, the unauthorized exposure of your personal data — regardless of whether it has been actively misused — can be sufficient grounds for a claim. The breach itself is the injury.
Nothing. The Law Office of David S. Harris handles data breach cases on contingency — you pay zero upfront and owe nothing unless compensation is recovered.
Immediately place a free credit freeze at all three bureaus (Equifax, Experian, TransUnion). A freeze blocks new accounts from being opened in your name. Then file a complaint with the FTC at IdentityTheft.gov and contact our office — SSN exposure is one of the most serious breach types.
Banks may reverse fraudulent charges, but they are not obligated to compensate you for time lost, stress, or indirect damages. A class action claim against the breached company can recover those additional categories of harm.
Statutes of limitations for data breach claims vary by state but typically run 2–4 years. Depending on when you learned of the breach, you may still have time. Contact our office for a free eligibility review — there is no cost to find out.
Accepting free credit monitoring from Commonwealth of Massachusetts Department of Revenue State does not waive your right to pursue legal action unless you signed a specific release waiving claims. In most cases, victims who accepted monitoring can still file.
Not necessarily. Many data breach victims are never notified directly. If your personal information was held by Commonwealth of Massachusetts Department of Revenue State during the relevant period, you may still qualify even without receiving a letter. A free eligibility review can confirm your status.
