Compensation/wages garnishee

We found out, through a communication from the IRS that an independent contractor we had used in the past, and contemplated using again, owes $90,000 to the IRS (certainly not only from what we paid him!). The IRS wants us to send any future compensation made to this person directly to them. My question applies to this person but also to prospective employees. Can we refuse to work with this person, or refuse to hire someone if, through a credit check or other means, we find out that their compensation is garnisheed by the IRS or the state or by a court order?
