TaxAct

TaxAct is a US tax filing service that lets people prepare and e-file their returns online. It has separate offerings for individuals, businesses and tax professionals, and the homepage emphasizes a guided process in which the software walks users through their information, with expert help available if they get stuck.

New customers can create an account and start a return for free, and the homepage describes a single flat price that covers the federal return and all state returns. The site also hosts tax resources and help content, and prominently shows customer ratings. TaxAct is a hosted commercial product, so returns are prepared and filed through the vendor's website rather than on your own servers.
