That would probably be used as evidence that you misclassified the "consultant" in the first place. The auto mechanic is actually a terrific example of what the IRS wants to see for a 1099 contractor. It's really for that situation exactly, and nothing else. If someone is working for you and only you, on a project that you designed the strategy, to be completed in the time-frame you dictated, and in the manner you dictate, if they are working in your office, with your supplies, with support from your staff, they are probably your employee. "He was only working for me on a special project" is not the criteria. No matter how many times I hear it, it is not the criteria.
