The home office deduction under IRC 280A allows self-employed individuals and certain business owners to deduct a portion of their housing expenses as a business deduction. The two requirements are (1) regular and exclusive use of a specific area of the home for business, and (2) it must be the principal place of business (or a place where the taxpayer regularly meets with clients, customers, or patients). Employees who work from home generally can’t claim this deduction after the TCJA eliminated the employee home office deduction for 2018-2025. The IRS offers two methods: the simplified method ($5 per square foot, up to 300 square feet, for a maximum $1,500 deduction) and the actual expense method (which calculates the business-use percentage of all home expenses including depreciation). The actual method often produces a significantly larger deduction but requires more recordkeeping and triggers depreciation recapture on the home when sold.

✓Key takeaway

Simplified vs. actual method comparison:

Factor	Simplified Method	Actual Expense Method
Calculation	$5/sq ft x office sq ft	Business % x total home expenses
Maximum deduction	$1,500 (300 sq ft max)	No cap (limited by business income)
Depreciation required	No	Yes (must depreciate the home’s business portion)
Depreciation recapture on sale	No	Yes (ordinary income on depreciation taken or allowed)
Recordkeeping	Minimal (just square footage)	Extensive (all home expenses)
Can switch methods	Yes, annually	Yes, annually
Reduces SE tax (sole prop)	Yes (Schedule C deduction)	Yes (Schedule C deduction)
Mortgage interest/property tax	Still deductible on Schedule A	Business portion on Schedule C, personal portion on Schedule A

Who qualifies:

Taxpayer	Qualifies?
Sole proprietor working from home	Yes (if regular/exclusive use test met)
S-Corp owner working from home	Yes (via accountable plan reimbursement from S-Corp)
Partnership member working from home	Yes (unreimbursed partnership expenses)
W-2 employee working from home	No (TCJA suspended through 2025)
Sole proprietor with separate office AND home office	Yes (if home is used regularly for admin/management and no other fixed location for those activities)

Requirements (both must be met):

Test	Details
Regular and exclusive use	A specific area used ONLY for business, on a regular basis (not occasional). Does NOT need to be a separate room, but the area can’t double as personal space
Principal place of business	Either (a) where most business activities occur, OR (b) where administrative/management activities occur and no other fixed location for those activities, OR (c) where clients/customers are regularly met

When should you use actual expenses instead?

Hypothetical example

Round numbers. A consultant. Sole proprietor. Works from a dedicated home office (200 sq ft in a 2,000 sq ft home). Business-use percentage: 10%.

Annual home expenses:

Expense	Total Annual Cost
Mortgage interest	$18,000
Property taxes	$8,000
Homeowner’s insurance	$2,400
Utilities (electric, gas, water, internet)	$6,000
Home repairs/maintenance	$3,000
Home depreciation (building cost $300,000 / 27.5 years residential)	$10,909
Total home expenses	$48,309

Simplified method:

Calculation	Amount
$5 x 200 sq ft	$1,000
Plus: full mortgage interest on Schedule A	$18,000
Plus: full property taxes on Schedule A (subject to SALT cap)	$8,000

Actual expense method:

Expense	10% Business Portion	Remaining Personal
Mortgage interest	$1,800 (Schedule C)	$16,200 (Schedule A)
Property taxes	$800 (Schedule C)	$7,200 (Schedule A)
Insurance	$240 (Schedule C)	N/A (not deductible personally)
Utilities	$600 (Schedule C)	N/A
Repairs	$300 (Schedule C)	N/A
Depreciation	$1,091 (Schedule C)	N/A
Total Schedule C deduction	$4,831

Comparison:

Method	Schedule C Deduction	SE Tax Savings (15.3%)	Income Tax Savings (22%)
Simplified	$1,000	$153	$220
Actual	$4,831	$739	$1,063
Difference	$3,831 more	$586 more	$843 more

The actual method produces $3,831 more in deductions and saves $1,429 more in taxes per year.

The depreciation recapture consideration: Under the actual method, the consultant depreciates the business portion of the home ($1,091/year). If the home is sold after 10 years:

Item	Amount
Total depreciation claimed (10 years)	$10,910
Depreciation recapture rate	25%
Recapture tax on sale	$10,910 x 25% = $2,728

Ten-year savings of $14,290 minus $2,728 recapture = $11,562 net benefit from using the actual method.

Important: depreciation recapture applies whether or not the taxpayer ACTUALLY claimed depreciation. If the taxpayer was entitled to claim it (used actual method), the IRS recaptures depreciation “allowed or allowable.” There’s no benefit to using the actual method but skipping the depreciation line.

S-Corp home office strategy: An S-Corp owner cannot deduct a home office directly on their personal return (they are a W-2 employee of the S-Corp). Instead:

Step	Action
1	S-Corp adopts a written accountable plan
2	Owner documents home office expenses and business percentage
3	Owner submits expense report to S-Corp
4	S-Corp reimburses owner (tax-free to owner, deductible by S-Corp)

The reimbursement is deductible by the S-Corp, tax-free to the owner, and NOT subject to FICA. A $4,831 reimbursement saves $739 in FICA compared to the same amount as additional salary.

Larger home office (bigger percentage): If the consultant dedicates 400 sq ft (20% of 2,000 sq ft):

Method	Deduction
Simplified	$1,500 (300 sq ft max, even though office is 400 sq ft)
Actual (20%)	$9,662
Difference	$8,162

The simplified method caps at $1,500 regardless of office size. For offices larger than 300 sq ft, the actual method’s advantage grows dramatically.

Can I take the home office deduction if I also rent outside office space?

Yes, but the home office must independently meet the IRS requirements: regular and exclusive use for business, and it must be your principal place of business or a location where you regularly meet clients. Having a separate office or studio does not disqualify the home deduction if you legitimately use both. The simplified method allows $5/sq ft up to 300 sq ft ($1,500 maximum). The regular method deducts the business percentage of actual home costs (mortgage interest, utilities, insurance, repairs, and depreciation).

What is depreciation recapture and why does it matter for the home office?

If you use the regular method, a portion of your home’s cost is depreciated each year (roughly 2.56% of the home’s value allocated to the office space). When you sell the home, the IRS recaptures that accumulated depreciation at a 25% rate, even if the rest of the gain qualifies for the IRC 121 primary residence exclusion ($250,000/$500,000). A home office used for 10 years in a $400,000 home with a 10% office allocation accumulates roughly $10,000 in depreciation, creating approximately $2,500 in recapture tax at sale. The simplified method avoids depreciation recapture entirely, which is why many homeowners prefer it despite the lower annual deduction.

Can you claim a home office deduction if you also rent office space?

Yes, having a separate office doesn’t automatically disqualify your home office deduction as long as your home office meets the regular and exclusive use test under IRC 280A. The home office must be your principal place of business or a place where you regularly meet clients, even if you also maintain another workspace. Under the Soliman test from the Supreme Court decision, a home office qualifies as your principal place of business if you perform substantial administrative or management activities there and have no other fixed location for those activities. The simplified method allows a $5 per square foot deduction up to 300 square feet ($1,500 maximum), while the regular method requires tracking actual expenses and calculating the business-use percentage of your home.
