The home office deduction is one of the most misunderstood deductions in small business tax. Some business owners skip it out of fear. Others claim it incorrectly and create unnecessary audit exposure. The truth is straightforward once you understand the rules.
The Two Requirements That Actually Matter
Regular and exclusive use. The space must be used regularly and exclusively for business. A desk in the corner of your bedroom that you also use for personal tasks does not qualify. A dedicated room used only for client calls and professional work does.
Principal place of business. Your home office must be either your primary business location or where you regularly meet clients and customers.
The Two Methods
Simplified method: $5 per square foot, up to 300 square feet ($1,500 maximum). Simple to calculate. No depreciation recapture when you sell the home.
Regular method: Actual expenses proportional to office size. More complex, often larger deduction. Involves depreciation of the home, which creates a taxable event when the property sells. The right method depends on your home expenses, office size, and long-term plans.
What Triggers IRS Scrutiny
Claiming a home office does not automatically trigger an audit. What does trigger scrutiny: claiming a space that does not meet the exclusive use test, claiming 100% of home expenses as business use, or inconsistency between reported home office income and expenses over multiple years.
What You Should Have Ready
A floor plan showing the office space and measurements. Receipts for home expenses. Evidence of business activity in the space. If you can produce this documentation on request, the deduction is solid.
