Based on your limited facts, I would analyze the businesses as independent contractors. You will have to issue them 1099s. Additional facts might change the analysis.
The above is general legal and business analysis. It is not "legal advice" but analysis, and different lawyers may analyse this matter differently, especially if there are additional facts not reflected in the question. I am not your attorney until retained by a written retainer agreement signed by both of us. I am only licensed in California.

As Mr. Doland has stated, based on the facts you've provided, these persons would not likely be considered employees. You would therefore not be required to withhold taxes, as you would for an employee, and would instead issue them 1099s.

These businesses are almost certainly independent contractors. However, being that employment misclassification is a very serious legal issue for many businesses, you would be prudent to have a business attorney review your independent contractor maintenance program/policy(ies). If these businesses are in fact independent contractors, you would not need to withhold taxes. Taxes are paid exclusively by the contractor.
