Working from home is common, but the home office deduction has strict requirements. Many taxpayers miss it entirely or claim it incorrectly. Here's what you need to know.
Who Can Claim the Home Office Deduction
This deduction is available to self-employed individuals, freelancers, and business owners. If you are a W-2 employee — even if you worked from home every day — you cannot claim a home office deduction under current tax law. The suspension of the employee home office deduction runs through 2025 under the Tax Cuts and Jobs Act.
The Two Requirements
To qualify, your home office must meet two tests:
-
Regular and exclusive use: The space must be used regularly and exclusively for business. A dedicated home office qualifies. Your kitchen table does not — even if you work there every morning.
-
Principal place of business: The office must be your main place of business, OR where you meet clients, OR a separate structure used exclusively for business.
Two Ways to Calculate the Deduction
Simplified Method
Deduct $5 per square foot of your home office, up to 300 square feet. Maximum deduction: $1,500. No depreciation to track. Simple math.
Regular Method
Calculate the percentage of your home used for business (office square footage ÷ total home square footage), then apply that percentage to actual home expenses: rent or mortgage interest, utilities, insurance, and depreciation.
The regular method typically produces a larger deduction but requires more recordkeeping.
What Expenses Are Included
Under the regular method, your deductible percentage applies to:
- Rent or mortgage interest
- Utilities (electricity, internet, gas)
- Homeowner's or renter's insurance
- Home repairs and maintenance
- Depreciation of the home (for owners)
Recordkeeping
Keep records of:
- Floor plan or measurements of the office and total home
- Receipts for all home expenses
- The business percentage calculation
If you're audited, the IRS will ask to see these documents.
Common Mistakes
- Claiming a room that also serves as a guest bedroom or playroom (fails the exclusive use test)
- Claiming the deduction as a W-2 employee
- Forgetting depreciation recapture when selling the home later
The Bottom Line
If you're self-employed and you have a dedicated workspace at home, the home office deduction is worth claiming. The simplified method is clean and audit-friendly. The regular method is worth it if you have a larger office or significant home expenses.
