Who qualifies
Two tests must be met. Regular use: you use the space for business on a continuing basis, not occasionally. Exclusive use: the space is used only for business, a spare room set up as your office qualifies; the corner of the living room where the family also watches TV does not. The space must also be your principal place of business or a place you regularly meet clients. Self-employed people, freelancers, and 1099 contractors qualify; W-2 employees generally cannot claim it federally since 2018.
The two methods
| Simplified | Regular | |
|---|---|---|
| How it works | $5 per sq ft | Business-use % of actual costs |
| Cap | 300 sq ft ($1,500) | No fixed cap |
| Records needed | Just the square footage | Rent/mortgage, utilities, insurance, etc. |
| Form | Schedule C worksheet | Form 8829 |
Worked example
Your office is 150 sq ft in a 1,500 sq ft home, a 10 percent business-use share. Simplified: 150 × $5 = $750. Regular: if your rent, utilities, and renters insurance total $24,000 for the year, 10 percent = $2,400. Here the regular method wins by $1,650, which is why it pays to compare.
What you can deduct under the regular method
- The business-use percentage of rent or mortgage interest
- Utilities (electric, gas, water), and internet used for the space
- Homeowners or renters insurance
- Repairs and maintenance for the home (business share)
- Depreciation, if you own the home
Keep the bills and a record of your square-footage calculation. NeoReceipt stores the receipts and bills that support these costs, so your home office figure is documented if the IRS ever asks.
