Under WV law, an employer cannot deduct the employer's cost of doing business
from the employee's wages. So, regardless of your agreement, if you were paying this person as an employee, then you could not deduct the $6,000 as a management fee.
However, the statute of limitations to recover unpaid wages in WV is 5 years. Goodwin v. Willard, 406 S.E.2d 752, 185 W.Va. 321 (WV Sup. Ct. 6/28/91). So, to the extent that the deductions were made more than 5 years ago, they are barred and cannot be recovered (assuming you plead the statute of limitations as an affirmative defense, in the event you are sued).
Hope this helps.
