Pa State Workers Insurance fund question.

[Account Closed]

When using the Pa State Workers Insurance Fund for workers compensation, do they force you to pay workers comp on uninsured sub-contractors.  I know the quick answer is yes but that is debatable.  

Pa SWIF has you fill out a questionnaire to establish the relationship between you and the contractor.  For example I hire a roofing company, which consists of 2 brothers with no workers comp, 2 hours from my home and it is a one time transaction plus they have their own tools, take no directions ext.  Those of you in the business know what I am talking about.  How does Pa really treat these scenarios during the audit process.  An example would be great.

Thanks.
