Tax filing services transmitting sensitive financial info to Facebook and Instagram

* Major tax filing services such as H&R Block, TaxAct, and TaxSlayer have been quietly transmitting sensitive financial information to [Facebook+Instagram].* As well as other basic personal information.

The do this through a tracking pixel on their web sites. The info sent comes from what the user enters in the web site; it seems that does not include the detailed financial data that users hand over for the tax return itself. Sending the latter to some other company might, I suspect, be a crime.

Millions of sites use the Facebook&Instagram tracking pixel to send data about their visitors.

Google Analytics collects much of the same data, but not the user's name. However, often it can figure out the user's identity in other ways.
