Home Office Deduction
The home office deduction allows self-employed people to deduct the costs of a home workspace used regularly and exclusively for business — a meaningful tax benefit for freelancers, consultants, and small business owners. It has two calculation methods: the simplified method ($5/square foot, up to 300 square feet = maximum $1,500 deduction) and the regular method (allocate actual home expenses — mortgage interest, property taxes, utilities, repairs, depreciation — by the percentage of your home used for business). The regular method can produce a much larger deduction for people with high housing costs, but requires more recordkeeping and can trigger depreciation recapture when you sell the home. The critical requirement: the space must be used regularly AND exclusively for business — a desk in a corner of a shared living room doesn't qualify; a dedicated room used only as an office does. Important caveat for W-2 employees: the TCJA of 2017 eliminated the employee home office deduction, meaning people who worked remotely as employees — even full-time from a dedicated home office — cannot deduct those expenses on their federal taxes. Only self-employed individuals and small business owners can claim the deduction.
Current Law (2026)
Self-employed individuals can deduct expenses for the business use of their home, using either the simplified or regular method.
| Method | Deduction |
|---|---|
| Simplified | $5/sq ft, up to 300 sq ft (max $1,500) |
| Regular | Actual expenses (mortgage interest, insurance, utilities, repairs, depreciation) prorated by business use % |
Key Numbers
- Simplified method ceiling: $5/sq ft × 300 sq ft maximum = $1,500/year maximum deduction; at the 22% federal bracket, this saves $330 in federal taxes; at the 24% bracket, $360; meaningful but modest for most filers
- Regular method advantage over simplified: a home office in a high-cost home can produce a much larger deduction — a 15% business-use share of a home with $30,000/year in total housing costs (mortgage interest, insurance, utilities, repairs) yields a $4,500 deduction vs. the $1,500 simplified maximum; for a 22% bracket taxpayer, that's $990 vs. $330 in tax savings
- Depreciation recapture trap: if you use the regular method for 10 years and depreciate $2,500/year of home office basis, you've accumulated $25,000 in depreciation; when you sell, that $25,000 is recaptured and taxed at 25% = $6,250 in recapture tax even if the rest of your home gain is excluded under the §121 primary-residence exclusion; the simplified method has zero recapture risk
- TCJA impact on employee home office: The Tax Cuts and Jobs Act (2017) eliminated the miscellaneous itemized deduction for employee business expenses, removing the home office deduction for all W-2 employees — affecting an estimated 15-20+ million employees who work from home at least part-time; the One Big Beautiful Bill Act of 2025 made this elimination permanent
- Audit risk: home office deductions on Schedule C are among the highest-examined items in IRS compliance programs; the IRS's document-matching systems flag home office deductions that are disproportionately large relative to business revenue or that are claimed alongside substantial W-2 income (which would suggest an ineligible employee claim)
Legal Authority
- 26 U.S.C. § 280A — Disallowance of certain expenses in connection with business use of home
How It Works
Under 26 U.S.C. § 280A, the home office deduction requires the space to be used exclusively and regularly for business — both parts of the test are enforced strictly. "Exclusively" means no personal use at all: a spare bedroom used entirely as an office qualifies; a desk in a corner of a room also used for sleeping, watching television, or storing personal items does not; a kitchen table where you also eat meals does not. "Regularly" means systematic and recurring business use — occasional use on nights and weekends doesn't satisfy the test. The home office must also be your principal place of business or a location where you regularly meet clients or customers in person. W-2 employees cannot claim this deduction under current law — the TCJA eliminated the miscellaneous itemized deduction for unreimbursed employee business expenses, and the One Big Beautiful Bill Act of 2025 made that elimination permanent. The deduction is available only to self-employed individuals, sole proprietors, and certain partners with qualifying home offices.
Two calculation methods exist. The simplified method is $5 per square foot, up to a maximum 300 square feet, producing a maximum deduction of $1,500. It requires no depreciation calculation and creates zero depreciation recapture risk when you sell your home — the simplicity comes with a hard ceiling. The regular method allocates actual home expenses — mortgage interest, insurance, utilities, repairs, and depreciation — by the percentage of the home's square footage used for business. On a high-cost home this substantially exceeds the simplified ceiling: a 15% business-use share of a home with $30,000 in annual housing costs yields a $4,500 deduction, saving $990–$1,080 at the 22–24% bracket vs. $330–$360 under the simplified method.
The regular method's larger deduction carries a meaningful hidden cost: the depreciation recapture trap. Using the regular method requires depreciating the home office portion of your home each year. When you sell, that accumulated depreciation is recaptured and taxed at 25% — even if the rest of the home's gain qualifies for exclusion under the Section 121 primary-residence exclusion ($250,000 single / $500,000 MFJ). Ten years of depreciating $2,500/year creates $25,000 in recapture, generating $6,250 in tax at sale. The simplified method has no such consequence. The right choice depends on office size, housing costs, and expected time in the home — but for most self-employed taxpayers in modest homes or with smaller offices, the simplified method's certainty often wins.
How It Affects You
If you're a freelancer or sole proprietor: Combine this with the business mileage deduction for maximum self-employment write-offs against your federal income tax. The simplified method ($5/sq ft up to $1,500) is usually the right call unless your home office exceeds 200 sq ft and your home expenses are substantial. For a 150-sq-ft office, the simplified method gives you $750. The regular method might beat that if your annual home expenses (mortgage interest, insurance, utilities, repairs) exceed $15,000 — but it also requires tracking every expense and calculating your business-use percentage. Most solo freelancers save time and audit risk by taking the simplified method.
If you're a W-2 remote worker: You cannot deduct home office expenses under current federal law, even if your employer requires you to work from home and doesn't reimburse you. Your main workaround is an accountable reimbursement plan through the employer, which can be tax-free to you and deductible to the business. Watch HR 1691 — if passed, it would partially restore this deduction through 2027.
If you run a business from a dedicated room: The "exclusive and regular use" test is strict. The IRS has denied deductions where a home office doubled as a guest bedroom, even occasionally. A 12x12 spare bedroom used solely as your office qualifies. A dining table you also eat dinner at does not — regardless of how many hours you work there.
If you're planning to sell your home: Choose your method carefully. The simplified method has no depreciation recapture consequences — you sell and the Section 121 exclusion ($250K single / $500K MFJ) applies to the whole home. The regular method requires you to depreciate the office portion of your home (see Section 179 expensing for related depreciation rules), and that depreciation is recaptured at 25% when you sell, even if the rest of the gain is excluded. On a $400,000 home with a 10% office, that could mean $3,000-$5,000 in unexpected recapture tax. See Home Sale Exclusion for the full rules on excluding gain from a primary residence sale.
If you meet clients at your home office: You automatically meet the "principal place of business" test if clients or customers physically come to your office. This is the easiest way to qualify if you also work at other locations.
Implementing Regulations
- 26 CFR Part 1 — Income tax regulations (§ 1.280A-1 through 1.280A-3 — disallowance of deductions for personal use of dwelling units, exceptions for business use of home, allocation of expenses, principal place of business test)
Pending Legislation
- HR 1691 (Rep. Grothman, R-WI) — Employee Business Expense Deduction Reinstatement Act of 2025: reinstates a partial deduction for unreimbursed employee expenses through 2027. Would partially restore home office deductibility for W-2 employees (currently limited to self-employed under TCJA). Status: Introduced.
Recent Developments
The One Big Beautiful Bill Act (2025) made permanent what TCJA started for employee home offices. TCJA (2017) temporarily eliminated the miscellaneous itemized deduction for unreimbursed employee business expenses — including home office expenses for W-2 employees — through 2025. When those provisions were set to expire, the OBBB Act extended and made permanent the elimination, meaning W-2 employees have no path to deduct home office expenses under current federal law regardless of how much time they spend working from home. This affects an estimated 15-20+ million remote employees. The elimination is particularly significant given the post-COVID explosion of permanent remote work arrangements; millions of employees who set up dedicated home offices have no federal tax relief for those costs unless their employer establishes an accountable plan reimbursement arrangement.
HR 1691 would provide a partial reprieve for W-2 employees — but faces a steep climb. The Employee Business Expense Deduction Reinstatement Act (introduced by Rep. Grothman, R-WI) would partially restore the deduction for unreimbursed employee business expenses through 2027, creating a pathway for W-2 remote workers to deduct home office and other unreimbursed work expenses. The bill has not advanced beyond introduction in the 119th Congress; its prospects are constrained by the revenue cost (restoring employee expense deductibility for millions of workers is expensive) and the political calculus of the TCJA/OBBB coalition that wanted the elimination made permanent. Employers who want to help remote employees can implement accountable plan reimbursements now — the tax-free employer reimbursement route is available under current law without waiting for legislation.
IRS audit attention to home office Schedule C deductions has increased with automated matching. The IRS's correspondence audit programs use automated document matching to flag returns where home office deductions appear alongside W-2 income — a combination that often indicates an ineligible employee claim disguised as a Schedule C deduction. If you're legitimately self-employed and claiming a home office, your documentation needs to be clean: a dedicated space (photos help), square footage calculation, business-use percentage, and records of home expenses allocated to the office. The simplified method's lower deduction amount also means lower audit risk than the regular method, since there's less to scrutinize — a factor worth weighing alongside the pure dollar-difference calculation between the two methods.
