Simplified vs. Actual Home Office Deduction: Which Method Saves More?
The home office deduction is one of the most commonly claimed and most commonly misunderstood deductions for self-employed business owners. It’s available to sole proprietors, single-member LLC owners, and partners who use a portion of their home regularly and exclusively for business. W-2 employees can’t claim the home office deduction (the TCJA/OBBBA permanently suspended the employee home office deduction for unreimbursed employee expenses). S-Corp shareholder-employees can have the S-Corp reimburse home office expenses through an accountable plan, which is a deduction on the corporate return rather than the individual return.
Two methods are available. The simplified method: $5 per square foot of the home office, up to 300 square feet, for a maximum deduction of $1,500. No depreciation, no tracking of actual expenses, and no depreciation recapture on sale of the home. The actual method: calculate the business-use percentage of the home (square footage of the office divided by total square footage), then apply that percentage to actual home expenses (mortgage interest or rent, property taxes, utilities, insurance, repairs, depreciation). The actual method produces a larger deduction in most cases, especially for homeowners in high-cost areas. A 200-square-foot office in a 2,000-square-foot home = 10% business use. If annual home expenses total $30,000 (rent/mortgage interest $18,000, utilities $4,800, insurance $1,200, property tax $6,000), the actual deduction is $3,000. The simplified deduction for the same office: 200 x $5 = $1,000. The actual method produces $2,000 more. The trade-off: the actual method requires record-keeping and creates depreciation recapture on sale of the home.
How do the two methods compare at different home costs?
What qualifies as “regular and exclusive use”?
The home office must be used “regularly and exclusively” for business. “Exclusive” means the space is used only for business, not as a guest bedroom, playroom, or family TV room. “Regular” means consistent use, not occasional.
Exceptions to the exclusive-use requirement:
- Home daycare providers (discussed separately, use the time-space percentage method)
- Storage of inventory or product samples (a clearly defined portion of the home used regularly for storage)
A bedroom that doubles as an office doesn’t qualify (fails the exclusive-use test). A dedicated room with a desk, computer, and filing cabinet that’s never used for personal purposes does qualify.
What about the depreciation recapture issue?
Homeowners who use the actual method must depreciate the business-use portion of the home. When the home is sold, the depreciation claimed (or that should have been claimed) is recaptured as ordinary income under IRC 1250, up to a 25% rate.
The simplified method avoids this entirely: no depreciation is claimed, so no depreciation recapture occurs on sale. For homeowners who plan to sell their home within a few years, the simplified method’s avoidance of depreciation recapture may outweigh the larger annual deduction from the actual method.
Renters do not have this issue (no depreciation on rent payments), so the actual method is almost always better for renters.
Can I claim the home office deduction if I also have an external office?
Yes, but only if your home office qualifies as your principal place of business or is used regularly to meet clients. Under IRS guidelines (Revenue Ruling 99-7), your home office is your principal place of business if you use it regularly and exclusively for administrative or management activities, and you have no other fixed location where you conduct substantial administrative work. A freelance consultant who meets clients at their offices but handles all invoicing, scheduling, and record-keeping from a dedicated home office qualifies. If you rent an external office for client meetings but do most substantive work at home, both spaces can be deductible for their respective uses. The simplified method ($5 per square foot, up to 300 sq ft / $1,500) makes this straightforward for smaller home offices.
