Tax filing websites TaxAct, H&R Block and TaxSlayer sent personal user and tax information to Facebook. The information included names, dependents, phone numbers, email addresses, filing status, refund amounts, adjusted gross income, dependents’ college scholarship amounts, health savings account usage, and refund amounts.
Intuit TurboTax also used the MetaPixel which allowed Facebook to track this information, but it only shared usernames in that case.
