Self-employed people who use part of their home exclusively and regularly for business can deduct either $5 per square foot of office space (up to 300 square feet, $1,500 maximum) or the business-use share of actual housing costs — rent or mortgage interest, utilities, insurance, and depreciation — on Form 8829. W-2 employees cannot claim the home office deduction, even for full-time remote work: the Tax Cuts and Jobs Act suspended it for employees in 2018, and the One Big Beautiful Bill Act (OBBBA) made that suspension permanent in July 2025. The rules and rates below apply to both 2025 returns (filed in 2026) and tax year 2026.
Key takeaways:
The home office deduction allows business owners to deduct expenses associated with using part of their home for business purposes. This deduction is authorized under Internal Revenue Code Section 280A and applies whether you own or rent your home.
Legal Basis: IRC §280A permits deductions for "a portion of a dwelling unit which is exclusively used on a regular basis as the principal place of business for any trade or business of the taxpayer."
The deduction isn't just for traditional "offices"—it applies to:
For a business owner with a 300 square foot office in a 1,200 square foot apartment renting at $2,000/month (25% business use), the actual-expense method produces:
The good news: If you run a business from home, you likely qualify. The bad news: The IRS has specific requirements you must meet.
✅ You CAN claim if you are:
❌ You CANNOT claim if you are:
No. The Tax Cuts and Jobs Act (TCJA) suspended the home office deduction for employees starting in 2018, and the One Big Beautiful Bill Act (OBBBA), signed July 4, 2025, made that suspension permanent by eliminating miscellaneous itemized deductions for good. Working from home full time, even at your employer's request, creates no deduction on your federal return. Two workarounds exist: ask your employer for an accountable-plan reimbursement (tax-free to you, deductible for them), or claim the deduction against a Schedule C side business you run from a separate qualifying space. A few states, California among them, never conformed to the TCJA change and still allow unreimbursed employee expenses on the state return.
Yes. The home office deduction works identically for renters and homeowners. Renters deduct the business percentage of rent, renters insurance, and utilities under the actual-expense method, or take the $5/sq ft simplified rate. Homeowners deduct mortgage interest, property taxes, insurance, and depreciation instead. Renters often come out ahead on the actual-expense method: rent is fully allocable, and there is no depreciation recapture to think about when moving out.
To qualify for the home office deduction, you must first meet three fundamental requirements as specified in IRS Publication 587:
You must use your home office regularly for business purposes.
What "regular" means:
Example:
✅ Sarah uses her home office 15 hours per week, every week → Qualifies
❌ Tom uses his home office once a month for paperwork → Doesn't qualify
You must use your home office space exclusively for business—not for personal activities.
What "exclusive" means:
Common Scenarios:
| Scenario | Qualifies? |
|---|---|
| Dedicated spare bedroom used only as office | ✅ Yes |
| Corner of living room with desk, used only for work | ✅ Yes |
| Guest bedroom with desk that hosts guests occasionally | ❌ No |
| Den with business desk and personal TV viewing | ❌ No |
Pro Tip: You don't need an entire room. You can use part of a room as long as that specific area is used exclusively for business. Consider using room dividers or furniture placement to clearly delineate your workspace.
You must actually be conducting a trade or business, not a hobby or investment activity.
Profit Presumption: If you show a profit in 3 out of 5 consecutive years, the IRS presumes you're in business (not a hobby).
After meeting the three threshold requirements, you must satisfy at least one of these five additional tests:
Your home office qualifies if it's your principal place of business.
You meet this test if:
A) You work only from home
B) You work in multiple locations, but do your most important work at home
C) You perform administrative/management activities at home with no other fixed location
Administrative/Management Activities Include:
Real-World Example:
Maria the Contractor
Maria is a general contractor who spends 80% of her time at job sites. She has a home office where she:
- Prepares bids and estimates
- Orders materials
- Does bookkeeping
- Schedules jobs
- Meets with subcontractors occasionally
Result: Maria qualifies! Even though most of her work happens at job sites, her home office is where she conducts all administrative activities, and she has no other fixed office location.
You qualify if you physically meet with clients, customers, or patients at your home office regularly.
Requirements:
Pro Tip: Keep an appointment book or calendar showing client visits to document this requirement.
You qualify if you use a separate freestanding structure on your property exclusively and regularly for business.
Qualifying Structures:
You qualify if you:
Special Benefit: You don't need exclusive use for inventory storage—just regular use of a specific area.
You qualify if you operate a licensed day care facility in your home for:
Once you've confirmed you qualify, it's time to calculate your deduction. The IRS offers two methods; run your numbers through both with our home office deduction calculator before you pick.
Introduced: Revenue Procedure 2013-13 (available from 2013 forward)
How it works:
Advantages: ✅ Extremely simple—no detailed record keeping ✅ No depreciation deduction (so no depreciation recapture when you sell your home) ✅ Can claim full home-related itemized deductions on Schedule A
Disadvantages: ❌ Capped at $1,500 ❌ Still limited to your business's gross income, and the shortfall cannot carry forward ❌ Usually results in smaller deduction than regular method
Example Calculation:
Home office size: 200 square feet
Calculation: 200 sq ft × $5 = $1,000 deduction
Legal Basis: IRC §280A, IRS Publication 587
You claim the regular method on Form 8829, filed with Schedule C. This section covers the calculation logic; for the form itself, our Form 8829 line-by-line guide walks through all 44 lines, the Line 11 Worksheet, and the carryover rules.
How it works:
Step 1: Calculate Your Business Percentage
You can use either approach (choose the one that gives you a larger percentage):
Option A: Square Footage Method
Business Percentage = (Office Square Feet ÷ Total Home Square Feet) × 100
Example:
Office: 400 sq ft
Home: 1,600 sq ft
Business %: (400 ÷ 1,600) × 100 = 25%
Pro Tip: You can exclude common areas (hallways, stairs, landings) and areas not used for business (attics, garages) from your total to increase your percentage.
Option B: Room Method
Business Percentage = (Rooms Used for Business ÷ Total Rooms) × 100
Requirements:
- All rooms must be approximately the same size
- Don't count bathrooms, closets, storage areas
Why Room Method Often Works Better: Unless you live in a mansion or have unusually large rooms, the room method typically yields a higher percentage and larger deduction.
Step 2: Identify Deductible Expenses
Definition: Expenses that benefit ONLY your home office.
Examples:
Deduction: 100% deductible
Definition: Expenses that benefit your entire home, including your office.
Examples:
Deduction: Business percentage only
SALT cap note: If the state and local tax cap ($40,000 on 2025 returns, $40,400 for 2026) limits your property tax deduction on Schedule A, the business share of those taxes is still deductible. Form 8829 moves it to the "excess real estate taxes" line, where it counts against business income instead.
Example:
Your annual home expenses:
- Rent: $24,000
- Utilities: $3,600
- Insurance: $1,200
- Total: $28,800
Business percentage: 25% Deduction: $7,200 ($28,800 × 25%)
If you own your home, you can also depreciate the business portion.
Depreciation Calculation:
1. Determine your home's adjusted basis (usually purchase price minus land value)
2. Multiply by your business percentage
3. Divide by 39 years (business use of a home is depreciated as 39-year nonresidential real property)
4. Result = Annual depreciation deduction
Important: When you sell your home, you must recapture (pay tax on) the depreciation you claimed, at a maximum rate of 25%. The home sale exclusion (up to $250,000 for single, $500,000 for married) still applies to the rest of your gain. Recapture only hits the actual-expense method; the simplified method claims zero depreciation. It also covers depreciation "allowed or allowable," meaning amounts you were entitled to claim even in years you skipped them, so if you use Form 8829, claim it.
Scenario:
Calculation:
| Expense | Amount | Business % | Deduction |
|---|---|---|---|
| Mortgage interest | $12,000 | 15% | $1,800 |
| Property taxes | $4,000 | 15% | $600 |
| Insurance | $1,500 | 15% | $225 |
| Utilities | $3,000 | 15% | $450 |
| Repairs | $2,000 | 15% | $300 |
| Direct expenses | $500 | 100% | $500 |
| Depreciation | $200,000 ÷ 39 | 15% | $769 |
| TOTAL | $4,644 |
Tax savings: the $4,644 deduction cuts self-employment tax by $4,644 × 92.35% × 15.3% = $656, and income tax by about $950 in the 22% bracket (slightly less than $4,644 × 22% because the deduction also shrinks the ½-SE-tax deduction). Combined: roughly $1,600.
Choose Simplified Method if: ✅ Your home office is small (under 300 sq ft) ✅ You want minimal paperwork ✅ You plan to sell your home soon (avoid depreciation recapture)
Choose Regular Method if: ✅ Your home office is larger than 300 sq ft ✅ You have high housing costs (rent/mortgage) ✅ You want to maximize your deduction ✅ You're willing to maintain detailed records
Tax Form: Schedule C (Form 1040), attach Form 8829
Profit Limitation: Your home office deduction cannot exceed the gross income from the business use of your home. The limit applies under both methods, but only the regular method lets you carry unused amounts forward to future years (Form 8829, lines 43-44).
Best Practice for S Corps: Set up an accountable reimbursement plan. Calculate your home office expenses and submit monthly or quarterly expense reports to your corporation for reimbursement.
Current rules (permanent under OBBBA):
❌ Wrong: Using your home office for business during the day and watching TV there at night
✅ Right: Using the space exclusively for business, keeping all personal activities in other areas
❌ Wrong: Setting up a desk but using it only occasionally
✅ Right: Using your home office consistently (ideally daily or at minimum several times per week)
❌ Wrong: Claiming your entire 1-bedroom apartment as office space when you clearly need somewhere to sleep
✅ Right: Being realistic about the space actually used exclusively for business
❌ Wrong: No measurements, no receipts, no records
✅ Right: Documented measurements, photos of office setup, organized expense receipts
❌ Wrong: Skipping the deduction due to audit fears or complexity
✅ Right: Claiming legitimate deductions you're entitled to
Reality check: IRS audit rates for sole proprietors have run near 1% or below in recent years, and proper documentation protects you if you are audited.
1. Home Office Measurements
2. Expense Records
3. Business Use Documentation
| Record Type | Retention Period |
|---|---|
| General home office records | 3 years from filing date |
| Records if you understated income by 25%+ | 6 years |
| Depreciation and home basis records | 3 years after you sell home |
| Employment tax records | 4 years |
| Property records (basis, improvements) | Indefinitely (until 3 years after sale) |
