Home office deduction qualification requirements
Your space has to pass two tests, plus one of three location tests:
| Test | Description |
|---|---|
| Exclusive use | The space is used only for business and not any personal tasks. |
| Regular use | You use the space on a consistent basis. |
| Location | The space serves as a principal place of business, a space where you meet clients, or a separate structure like a detached studio. |

Why W-2 employees generally can’t claim the home office deduction
The 2017 Tax Cuts and Jobs Act suspended unreimbursed employee business expense deductions, and that suspension has continued through recent tax years. So if you’re a salaried or hourly employee who gets a W-2, working from home—even full time, even if your employer requires it—doesn’t qualify you for this deduction.
However, if you also earn self-employment income reported on Schedule C, you can claim the home office deduction for that portion of your work, even while holding down a separate W-2 job.
Simplified method vs. actual expense method
| Method | How it works |
|---|---|
| Simplified | $5 per square foot of office space, capped at 300 square feet ($1,500 max). No depreciation to track or recapture later. |
| Actual expenses | Multiply the percentage of your home used for business by your real costs—rent, utilities, insurance, repairs—plus depreciation if you own your home. While there’s no flat dollar cap, the home office deduction generally can’t create or increase a business loss and may be limited by your business income. Any deduction that exceeds your gross business income may be carried forward to the next tax year. |

The simplified method skips depreciation entirely, which also means nothing to recapture if you sell your home later.
The actual expense method often deducts more, but it requires more recordkeeping and is reported on Form 8829. If you own your home, you may also be able to deduct depreciation under the actual expense method, but that can affect your taxes if you sell the home later.
Home office tax deduction example
Say your home office is 200 square feet in a 2,000-square-foot home.
- Business-use percentage: 200 ÷ 2,000 = 10%
- Simplified method: 200 × $5 = $1,000 deduction
- Actual expense method: $18,000 × 10% = $1,800 deduction
