Companies such as H&R Block, TaxAct, and TaxSlayer have allegedly been sending Facebook "not only information like names and email addresses but often even more detailed information, including data on users’ income, filing status, refund amounts, and dependents’ college scholarship amounts," a report from the Verge said on Tuesday.

The information "can be used by the company to power its advertising algorithms," the outlet claimed, and it is "gathered regardless of whether the person using the tax filing service has an account on Facebook or other platforms operated by its owner Meta."
