Home Office Deduction

Home Office Deduction

A reduction in one's taxable income for the expenses of maintaining a home office. For example, a self-employed person may deduct the costs of office supplies, depreciation on one's computer and similar expenses. Likewise, one may deduct a portion of one's rent or mortgage for an office space used exclusively for business purposes. However, the amount deducted must be proportionate to the office's size relative to the home. Employees who work from home are eligible for the same deduction under the same restrictions.
