So basically you are an employee of the leasing company if I understand you correctly. Your business collects revenue from its patrons, and pays expenses including a payment to the leasing company for your own services.
Your 1040, Schedule C will show gross revenue and expenses of the business. One of these expenses will be for contract labor (yours). The net profit of the business will then be subject to the self-employment tax. The amount of draws does not affect this tax.
Hope this has been helpful. Please click Reply if I can be of further assistance.
