Yes this is true for Wisconsin but the rule is very specific. In Wisconsin a small business must carry workers’ compensation insurance if it meets either of these conditions: The business has 3 or more full time or part time employees It has 1 or more employees and has paid $500 or more in total gross wages in any calendar quarter for work performed in Wisconsin (dwd.wisconsin.gov) Coverage becomes required as soon as the third employee is hired or by the 10th day of the first month of the next quarter once the $500 wage threshold is met (dwd.wisconsin.gov) Most types of workers including part time employees family members and minors are generally counted as employees under Wisconsin law with limited exceptions (dwd.wisconsin.gov) So even very small businesses often become subject to the requirement earlier than expected.
