It is actually possible for a U.S. company to employ you directly as an employee (according to ASVG) in Austria without forming a legal entity. They of course have to pay Employer contribution to social insurance and other things (DB zum Familienlastenausgleichsfond etc.), and you as employee have to also pay the employee contribution to social insurance and income taxes. You probably want to hire a tax accountant to handle your monthly payslips etc. (Disclaimer: This is not legal advice, I’m not a tax accountant/lawyer.)
