How the Home Office Deduction Works
Simplified method vs. actual expense method
The home office deduction lets self-employed individuals deduct expenses for the portion of their home used regularly and exclusively for business. This applies whether you own or rent, and covers a house, apartment, condo, or even a mobile home.
Simplified Method:
- Deduct $5 per square foot of home office, up to 300 square feet
- Maximum deduction: $1,500/year
- No need to track individual home expenses
Regular (Actual Expense) Method:
- Calculate business-use percentage (office sq ft ÷ total home sq ft)
- Apply percentage to actual home expenses: mortgage interest or rent, utilities, insurance, repairs, depreciation, and more
The regular method typically yields a larger deduction if your home office is more than 300 sq ft or your housing costs are high. The simplified method saves time but caps your deduction at $1,500.
Important: W-2 employees cannot claim the home office deduction, even if they work from home. This deduction is exclusively for self-employed individuals, independent contractors, and business owners who file Schedule C.
Qualifying for the Home Office Deduction
Two IRS tests you must meet
1. Regular Use The space must be used for business on a consistent, ongoing basis — not just occasionally.
2. Exclusive Use The space must be used only for business. A desk in a bedroom that's also used personally doesn't qualify. A dedicated room or partitioned space does.
Exceptions to the exclusive use rule:
- Daycare facilities: Space doesn't need exclusive business use if you operate a licensed daycare from home.
- Storage of inventory: Product inventory or samples stored at home for business, where your home is your only fixed business location.
Bonus: Having a qualifying home office makes your mileage deduction more valuable. When your home is your principal place of business, every trip from home to a business destination becomes deductible — eliminating the "commute" exclusion that would otherwise apply.
What Expenses Can You Deduct?
Direct and indirect home office expenses
Direct expenses (100% deductible — only benefit your office):
- Painting or repairs to the office room
- Dedicated office furniture and equipment
Indirect expenses (deductible at your business-use percentage):
- Rent or mortgage interest
- Property taxes
- Homeowner's or renter's insurance
- Utilities (electricity, gas, water, internet)
- Home repairs and maintenance
- Depreciation (if you own)
- Security system
- HOA fees
Example: If your home office is 200 sq ft in a 2,000 sq ft home (10% business use) and your annual housing costs total $24,000, your deduction would be $2,400 — significantly more than the simplified method's $1,000 (200 × $5).
Track these expenses automatically with SparkReceipt — snap photos of utility bills, insurance statements, and repair receipts, and they're categorized and stored for tax time.
Frequently Asked Questions

The regular (actual expense) method usually gives a larger deduction if your office is over 300 square feet or your housing costs are high. The simplified method ($5/sq ft, max $1,500) is easier — no expense tracking needed. Use this calculator to compare both methods with your actual numbers.
The home office deduction does not automatically trigger an audit. The IRS has stated this is a common misconception. As long as you legitimately qualify (regular and exclusive use) and keep proper records, claiming this deduction is perfectly safe. Millions of self-employed taxpayers claim it every year.
Yes, you can deduct the business-use percentage of your internet bill using the regular method. If your business-use percentage is 15%, you can deduct 15% of your annual internet costs. With the simplified method, internet costs are not separately deductible — they're included in the $5/sq ft rate.
