Home Office Deduction — Deduct Your Home Expenses as a Self-Employed Business Owner
What Is It?
If you are self-employed and use part of your home regularly and exclusively for business, you can deduct a portion of your home expenses — including rent (or mortgage interest), utilities, insurance, repairs, and depreciation — as a business expense on your federal tax return. This deduction can reduce your self-employment income dollar-for-dollar, cutting both your income tax and your self-employment tax (which alone is 15.3% on net self-employment income).
The IRS provides two calculation methods: the simplified method (easy, limited deduction) and the regular method (more complex, potentially larger deduction). You choose each year, and you can switch between them annually.
Important: Employees who work from home — even full-time remote workers — cannot claim this deduction under current federal law. The Tax Cuts and Jobs Act of 2017 (P.L. 115-97) suspended the employee home office deduction through 2025, and it has not been restored. This deduction is available only to self-employed individuals filing Schedule C, partners in a partnership, and certain shareholders of S-corporations.
The Two Calculation Methods
Method 1: Simplified Method
Introduced in 2013 (Revenue Procedure 2013-13), the simplified method calculates your deduction as:
$5 per square foot of your home used for business, up to a maximum of 300 square feet.
Maximum deduction under the simplified method: $1,500 (300 sq ft × $5).
Pros:
- No calculation of actual home expenses required
- No depreciation of the home (and therefore no depreciation recapture when you sell)
- No carryover limitation — if your business has a loss, you simply lose the deduction for that year
- Easy to document
Cons:
- Capped at $1,500 regardless of your actual expenses
- Generally inferior for homeowners with expensive homes or high utility costs
Method 2: Regular Method (Actual Expense Method)
The regular method requires calculating the percentage of your home used for business (business square footage ÷ total home square footage) and applying that percentage to your total home expenses.
Example: 200 sq ft office in a 2,000 sq ft home = 10% business use.
Deductible expenses fall into two categories:
-
Direct expenses — costs that apply only to your office space (painting the office, repairing the office floor) — deductible at 100%.
-
Indirect expenses — costs for the whole home — deductible at your business-use percentage (10% in the example above):
- Rent (if you rent) or mortgage interest + property taxes (if you own)
- Utilities (electricity, gas, water)
- Homeowners or renters insurance
- General home repairs and maintenance (roof repair, HVAC service)
- Security system fees
If you own your home, you can also deduct depreciation on the business portion of your home. The business-use portion of the home’s cost basis is depreciated over 39 years (commercial property schedule under MACRS). This significantly increases the deduction but creates a depreciation recapture issue when you sell (see below).
Gross income limitation: Under the regular method, your home office deduction cannot exceed your gross income from the business use of the home. If your business has a net loss, the deduction may be limited in the current year and carried forward to future years.
Step-by-Step: How to Claim It
Step 1 — Verify you meet the “exclusive and regular use” test. This is the most important requirement and the most common audit trigger. Your office space must be:
- Used regularly — on a consistent, ongoing basis (not just occasionally)
- Used exclusively — for business only; not shared with personal use
A dedicated room used only as your office qualifies. A kitchen table, living room couch, or shared guest room that doubles as an office does not qualify — even if you spend significant time working there. The IRS interprets “exclusive” strictly. If the space contains a personal TV, a children’s play area, or personal storage, it does not qualify.
Step 2 — Measure your office space. Use a tape measure — do not estimate. The square footage of your office space must be the actual, measurable area used exclusively for business. Keep a note of the measurement in your records.
Step 3 — Confirm your home office is your principal place of business. For a deduction under the principal place of business test (the most common), the home office must be:
- Your main place where you conduct business (administrative and management activities count even if you see clients elsewhere), OR
- A place where you regularly meet clients or customers, OR
- A separate structure on your property used for business
If you have another office you use regularly (e.g., a coworking space you pay for), you can still qualify if the home office is where you conduct administrative and management activities and there is no other fixed location where you substantially perform these functions.
Step 4 — Choose your method and complete the right form. For Schedule C filers:
- Simplified method: Report the deduction on Schedule C, Line 30. No additional form required. Note the square footage used and the prescribed rate in your records.
- Regular method: Complete IRS Form 8829 (Expenses for Business Use of Your Home) and carry the result to Schedule C, Line 30.
Step 5 — Document everything. The documentation that protects you in an audit:
- A floor plan or sketch of your home showing the dedicated office space with measurements
- Receipts or statements for all home expenses claimed (utility bills, insurance, mortgage statements)
- A log or calendar showing regular business use of the space (helpful for demonstrating regularity)
- Photographs of the dedicated office space (timestamped)
What Most People Don’t Know
-
Renters can deduct the office portion of their rent. You do not need to own your home. A renter who pays $2,000/month for a 1,000 sq ft apartment and uses a 150 sq ft room exclusively for business can deduct 15% of rent = $300/month = $3,600/year. This is frequently overlooked by self-employed renters.
-
Depreciation recapture applies when you sell your home. If you use the regular method and take depreciation on the business portion of your home, the IRS will recapture that depreciation when you sell — taxing it at 25% even if the rest of your home gain is excluded under the Section 121 principal residence exclusion. The recapture applies to the amount of depreciation taken (or allowed) during the period of business use, not the entire business portion of the gain. The simplified method avoids this entirely.
-
The exclusive use test has no de minimis exception. Even 5 minutes of personal use of the space can technically disqualify the entire deduction. However, incidental personal use that is not planned or regular (e.g., taking a personal call in your office) does not disqualify the space. What will disqualify it: a couch where family members watch TV, a closet where personal items are stored, or a desk shared with a child for homework.
-
Employees cannot use this deduction (as of 2026). The Tax Cuts and Jobs Act suspended the miscellaneous itemized deduction for unreimbursed employee business expenses (which included home office) from 2018 through at least 2025. Unless Congress acts to extend or restore it, W-2 employees working from home get no federal tax deduction for their home office. Self-employed individuals are unaffected.
-
You can deduct both a home office and other business expenses. The home office deduction does not preclude other deductions. You can claim your home office plus your phone, internet (the business-use portion), supplies, equipment, and travel.
-
Internet can be partially deducted separately. Your internet bill is generally deductible as a direct business expense (on a different Schedule C line) to the extent you use it for business — separate from and in addition to the home office deduction.
-
The simplified method cannot create or increase a business loss. If your net self-employment income before the home office deduction is $1,200, your simplified deduction is capped at $1,200 (not the full $1,500). The regular method has a similar gross income limitation with a carryover mechanism.
Common Audit Triggers to Avoid
- Claiming a home office for a business with little or no revenue (raises questions about business purpose)
- Using estimated or rounded square footage numbers rather than measured figures
- Claiming a shared space (guest room, kitchen area) as exclusive business use
- Deducting the full cost of expenses that are clearly personal (landscaping, pool maintenance) as home office expenses
- Year after year of losses from a business claiming a home office (the IRS may question whether it is a legitimate business or a hobby)
- Claiming both the Augusta Rule rental income exclusion and the home office deduction for the same space in the same year
Who Benefits Most?
- Sole proprietors and freelancers who work from home and have a dedicated workspace
- Independent contractors (Uber drivers with home dispatch, real estate agents doing admin from home, consultants)
- S-corporation or LLC members who take an accountable plan reimbursement from their entity for home office expenses (a different but related strategy)
- Self-employed individuals in high-cost housing markets where even 10–15% of rent or mortgage interest represents a significant deduction

Frequently Asked Questions
Can remote employees working from home claim the home office deduction?
No. Under current federal law, W-2 employees cannot claim the home office deduction. The Tax Cuts and Jobs Act of 2017 suspended the miscellaneous itemized deduction for unreimbursed employee business expenses through at least the end of 2025, and it has not been restored. This deduction is available only to self-employed individuals, sole proprietors, and certain partners or S-corporation shareholders.
What does “exclusive use” actually mean — can I have a chair or bookshelf in my home office with any personal items?
The IRS interprets “exclusive use” strictly. The space must be used solely for business — no personal TV, no children’s homework area, no personal storage. Incidental personal use (taking a personal phone call in your office) generally does not disqualify the space, but regular mixed use does. A dedicated room with only business furniture and equipment is the safest structure.
Is the simplified method ($5/sq ft) or the regular method better?
It depends on your situation. The simplified method is capped at $1,500 (300 sq ft × $5) and avoids depreciation recapture when you sell your home. The regular method can produce a much larger deduction — especially for homeowners or those in high-rent markets — but requires tracking actual expenses and triggers depreciation recapture on sale. Renters in expensive cities often benefit significantly more from the regular method.
If I take depreciation on my home office under the regular method, what happens when I sell my house?
The IRS will recapture the depreciation you took (or could have taken) during business use, taxing it at a 25% rate when you sell — even if the rest of your home gain is excluded under the Section 121 principal residence exclusion. The simplified method avoids this entirely, which is one reason some homeowners prefer it despite its lower deduction ceiling.
Can I deduct my internet bill in addition to the home office deduction?
Yes. Your internet bill is generally deductible as a direct business expense on a separate Schedule C line, to the extent you use it for business — separate from and in addition to the home office deduction. You can allocate a reasonable business-use percentage (e.g., 80% if you work from home full-time) and deduct that portion.
