Gusto and Texas Third Party Authorization
Updated over a week ago


Running payroll as an employer has many requirements. One of them is submitting quarterly payroll reports to the state. The reports contain a summary of gross wages paid to employees and payroll taxes sent to the state. Gusto handles this for you. Most states simply receive the report from Gusto on your behalf. Texas is special and requires you, and only you, to authorize Texas that it is ok to receive these reports from Gusto. So far we've handled the majority of the work of forming your LLC, processing your S Corp election, and even registering you as an employer with the state. Texas requires this last part to be done by you.
