Home Office Deduction for STR Investors: Simplified vs Actual

STR investors managing properties from home — taking calls, processing bookings, maintaining records, scheduling cleaners — may qualify for the home office deduction under IRC §280A. The mechanics: a portion of your home used regularly and exclusively for business is deductible. Two computation methods exist: the simplified method (flat $5/sqft up to 300 sqft, $1,500 max) and the actual expense method (percentage of home × actual expenses). For most single-property STR operators, simplified is sufficient; multi-property operators with dedicated office space often benefit from actual.

The eligibility tests

• Regular use: The space is used regularly for business, not occasionally.
• Exclusive use: The space is used ONLY for business — not also as a guest bedroom, family room, or personal study.
• Principal place of business: The space is your principal place of business OR a place you meet clients OR a separate structure.
• Business activity: Your STR management activities must constitute a trade or business OR be tied to a Schedule C STR (substantial-services properties).

Simplified vs actual computation

Simplified method: 300 sqft × $5 = $1,500 maximum deduction. No depreciation tracking, no actual-expense allocation, no recapture concern at home sale. Actual method: compute the business-use percentage (sqft of office / total sqft of home), apply that percentage to actual home expenses (mortgage interest, utilities, insurance, repairs, depreciation). Often produces larger deductions for higher-income operators with substantial home expenses, but creates basis-tracking complexity and depreciation-recapture exposure at home sale.

Schedule E vs Schedule C interaction

Pure Schedule E rental real estate (no substantial services) generally doesn't support a home office deduction directly — the IRS has historically taken the position that rental real estate isn't a 'trade or business' under §280A's standard. Operators with Schedule C STR (substantial services) qualify cleanly. Operators in the gray zone (multiple properties, active management, near-trade-or-business operations) can sometimes claim home office on a separate Schedule C reflecting their property-management business; consult a tax professional for the right entity structure.

How this fits with cost segregation

Home office deductions are separate from cost-segregation deductions on rental property. Cost-seg generates depreciation deductions on the rental property's building components; home office deductions allocate expenses on your personal residence's office space. Both can apply simultaneously for STR operators who qualify. The combined Schedule E + home office reduction can be substantial. Watch home-office depreciation recapture if you sell your home (selling a home with claimed home-office depreciation triggers recapture on that portion). See cost segregation for Airbnb properties.
