Major tax prep companies TaxSlayer, H&R Block, and TaxAct have been accused of sharing “millions of taxpayers’ data” with Meta and Google by a July 2023 Congressional report.
All three services had been found to be using tracking pixels, which were sharing information like filing status, approximate adjusted gross income, approximate refund amount, names of dependents, types of income, and approximate federal tax owed. In some cases, full names, emails, addresses, phone numbers, and genders were being shared as hash values.
