Relative of an employee of FreeTaxUSA/TaxHawk.

The two sites are targeting different kinds of people. That's why they exist. They are the same (and same company) because in the end, everyone has to go through the same processes for taxes.

As for keeping the tax return data on their server, it's for convenience and possibly for other reasons. My relative believes that, for legal reasons, FreeTaxUSA is considered a "tax preparer" and needs to keep those records.
