Three things to know before claiming
- Regular and exclusive use: The space must be used regularly AND exclusively for business. A desk in your bedroom that doubles as a dressing area doesn't qualify. A dedicated office room or a clearly delineated corner does.
- W-2 employees can't claim it: The 2017 TCJA eliminated unreimbursed employee business expenses through 2025. Only self-employed (Schedule C / 1099) filers can take this deduction federally.
- Capped at business net income: The deduction can't create a Schedule C loss. If your business net income is $5,000 and the deduction is $8,000, only $5,000 is allowed; the rest carries forward.
Questions
Frequently asked questions
Who can claim the home office deduction?
Self-employed individuals, freelancers, gig workers, and small business owners using part of their home regularly and exclusively for business. W-2 employees CANNOT claim home office expenses on their federal return — the 2017 TCJA eliminated unreimbursed employee expenses through 2025. The deduction is reported on Schedule C (or Form 8829 for the actual expense method).
What does 'regular and exclusive use' mean?
The space must be used regularly (not occasionally) AND exclusively for business — meaning it can't double as a guest bedroom, a kid's homework spot, or a dining room. A dedicated room is the cleanest qualifier. A clearly defined workspace within a larger room can also qualify if it's clearly delineated and used only for business. The IRS does not require it to be physically walled off.
Simplified vs actual method: which gives a bigger deduction?
Actual usually gives a bigger deduction if you have meaningful home expenses (rent, mortgage interest, utilities) — especially if your office is more than ~150 sqft. Simplified caps at $1,500 (300 sqft × $5). Run the calculator above to see your specific numbers. The trade-off: actual method requires careful expense tracking and may create depreciation recapture when you sell (if you own).
Does the home office deduction trigger an audit?
It used to (more aggressively in the 1990s-2000s), but it's commonplace now and not a major audit flag on its own. What does increase audit risk: the actual expense method with implausibly large business-use percentages, claiming home office while reporting a Schedule C loss, and treating areas that don't meet 'exclusive use' as office space. The simplified method has lower audit visibility because it's a single line item.
Can I claim home office if I rent my home?
Absolutely — the deduction works whether you rent or own. Renters use their monthly rent (× 12) as the major expense input under the actual method. There's no depreciation issue when you sell because you don't own the property. For renters, the actual method often beats simplified because annual rent × business-use% is usually large.
What's the depreciation recapture issue for homeowners?
If you use the actual method as a homeowner, you depreciate the office portion of your home (39-year non-residential life on the cost basis). When you sell, the IRS recaptures that depreciation at up to 25% — even if your sale qualifies for the §121 primary-residence capital gains exclusion. The simplified method does NOT create depreciation recapture, which is one of its biggest underrated advantages for homeowners planning to sell.
