Who qualifies?
You qualify for the home office deduction if you meet both of these tests:
- Regular and exclusive use: You use part of your home exclusively and on a regular basis for business. A desk in your bedroom that you also use for gaming doesn't count. A converted spare room does.
- Principal place of business: Your home office is your main place of business, or a place where you regularly meet clients.
Self-employed individuals (sole proprietors, freelancers, independent contractors) almost always qualify. W-2 employees generally do not, even if they work from home.
Simplified method vs. regular method
The IRS gives you two options:
Simplified method: $5 per square foot of your home office, up to 300 square feet. Maximum deduction: $1,500. No depreciation calculations, no tracking utility bills. Most small business owners use this.
Regular method: Calculate the percentage of your home used for business (by square footage), then apply that percentage to actual expenses: mortgage interest or rent, utilities, insurance, repairs, depreciation. More paperwork, but potentially a bigger deduction if your home office is large or your expenses are high.
Your home is 1,500 sq ft. Your office is 150 sq ft. That's 10% of your home.
Simplified: 150 sq ft × $5 = $750 deduction
Regular: 10% of your $24,000/yr rent + $3,600 utilities + $1,200 insurance = 10% of $28,800 = $2,880 deduction
See IRS Publication 587 (Business Use of Your Home) and Form 8829 for the regular method. The simplified method is reported directly on Schedule C, Line 30.

- Dual-use spaces don't count. Your kitchen table where you sometimes work? Not deductible. It needs to be exclusive.
- Forgetting to track expenses year-round. If you use the regular method, you need 12 months of utility bills, not a guess in April.
- Claiming it as a W-2 employee. The Tax Cuts and Jobs Act eliminated the home office deduction for employees (2018-2025).
