For business owners with disabilities, certain costs are necessary to perform their work effectively. The IRS recognizes this and provides a special rule for deducting these costs, known as Impairment-Related Work Expenses (IRWE). These are treated as ordinary and necessary business expenses, allowing individuals to deduct costs for attendant care and other essential services.

This guide explains what qualifies as Impairment Related Work Expenses, the specific IRS rules you must follow, and how to track these important expenses for tax purposes.

Medical expenses are deducted separately on Schedule A (Form 1040) and are subject to different rules and limitations.
