Many physician shareholders in S corporations incur expenses out of their own pocket that do not get or have not yet been reimbursed by the corporation. If "ordinary and necessary" to the corporation’s business, the corporation deducts these expenses on its tax return.
A recent tax case addressed this issue:
The Tax Court redetermined deductible amount of S corp. shareholder/vice pres.’s unreimbursed employee business expenses. Pursuant to corp.’s expense assumption/non-reimbursement resolutions, car, truck, supplies, subscription and partial post office box rental expenses were taxpayer’s own, not corp.’s, and were deductible by him to extent ordinarily and necessarily incurred as part of his business of serving as corp. employee and maintaining corp. office; but, Code Sec. 67 ‘s 2 % floor and Code Sec. 68 ‘s limitations applied. Also, depreciation expenses, although relating to covered truck and office equipment expenses, were denied for lack of substantiation. (Ronnie O. Craft, et ux. v. Commissioner, (2005) TC Memo 2005-197 , 2005 RIA TC Memo ¶2005-197 )
