Taxpayer has a small business and is also a W-2 employee in similar type work. Through his self-employment business, he has access to better rates for some material than his employer. He purchases material through his self-employment business and "sells" same product to W-2 employer at same rate of purchase. Would that be considered a reimbursement and not be considered as income/deduction for his self-employment business being there is no mark-up or should it be considered income/deductions that basically wash each other out on Schedule C?
