Home Office Deduction for US Freelancers: Form 8829 Explained
How to claim the home office deduction using Form 8829 or the simplified method — including the exclusive-use rule, what expenses qualify, and how to calculate the deduction correctly.

The home office deduction lets self-employed workers deduct a portion of home expenses — rent, mortgage interest, utilities, insurance, repairs — based on the percentage of the home used for business. It's one of the most valuable deductions for remote freelancers, but also one of the most misunderstood.
The Exclusive-Use Requirement
The IRS requires that your home office space be used 'regularly and exclusively' for business. This means a dedicated room or clearly defined area — your kitchen table where you also eat dinner doesn't qualify. The exclusive-use rule is strictly enforced; one auditor can disallow the entire deduction if personal use is evident.
Two Methods for Calculating the Deduction
- Simplified method: $5 per square foot, up to 300 sq ft = max $1,500 deduction
- Regular method (Form 8829): office sq ft ÷ total home sq ft × eligible home expenses
- Regular method typically yields a larger deduction for larger offices or higher housing costs
- You can switch methods from year to year
What Expenses Are Included (Regular Method)
- Rent (renters) or mortgage interest + real estate taxes (owners)
- Utilities: electricity, gas, water proportional to office use
- Homeowner's or renter's insurance
- Repairs and maintenance to the home
- Depreciation of the home (owners only — triggers recapture on sale)
Home office expenses require careful documentation. ReceiptOne captures utility bills, insurance statements, and repair receipts throughout the year — so your Form 8829 is accurate and audit-ready.
The Income Limitation
The home office deduction cannot exceed your net business income from that business. If you're in a loss year, the excess carries forward to the next year — it isn't lost. This limits the deduction's value in low-income years but makes it fully recoverable when business picks up.
