What happened
Harvey & Martin, PLLC ("Harvey & Martin"), a North Andover, Massachusetts accounting and tax preparation firm, noticed an unusually high number of IRS e-file rejection notices and identity-verification requests tied to certain clients' 2025 tax returns. An internal investigation conducted with outside cybersecurity professionals confirmed that an unauthorized party obtained files belonging to a subset of the firm's clients.
Harvey & Martin began mailing notification letters on or around June 11, 2026 and reported the incident to the Massachusetts Attorney General on June 23, 2026. The firm has stated that the information involved may include names, Social Security numbers, and bank account numbers where a bank account number was included on the affected tax return. Harvey & Martin reported the breach to state regulators for 111 Massachusetts residents and is offering 24 months of single-bureau credit monitoring through Cyberscout (a TransUnion company).
Because the exposed data includes Social Security and bank account numbers tied to tax filings, affected clients may face an elevated risk of fraudulent tax returns and financial account fraud. Whether the firm's pre-breach security practices met legal standards, and whether the timing of notification caused additional harm, are among the issues being evaluated.
