That's a strange name for something that cost money.
I've used them for the past several years, never had any issues. Paid for audit defense one year when my return was especially complex (luckily haven't needed it yet).
They have up selling services like a prepaid debit card and whatnot, but all that is optional.
I'm really happy to use FreeTaxUsa and only pay $20 for my income tax though, because using TurboTax with contractor income it was $120 or more. I got multiple family members to switch to FreeTaxUsa.
