Form 8829: Home Office Deduction for H-1B Households
If your H-4 EAD spouse runs a business from home, Form 8829 calculates the deductible portion of home expenses. This guide explains the regular method vs. simplified method, qualification rules, and how the deduction flows to Schedule C.
What Is Form 8829?
Form 8829, "Expenses for Business Use of Your Home," computes the deduction for using part of your home regularly and exclusively for business. The deduction covers a proportionate share of mortgage interest or rent, property taxes, utilities, insurance, repairs, and depreciation.
The deduction is available only to self-employed individuals (Schedule C filers). W-2 employees cannot claim a home office deduction under current law — the Tax Cuts and Jobs Act suspended the unreimbursed employee expense deduction through 2025.

Who Qualifies?
To claim the home office deduction, you must meet two tests:
- Regular and exclusive use: The space must be used regularly for business and exclusively for business. A corner of the living room that doubles as a play area does not qualify. A dedicated spare bedroom used only as an office does.
- Principal place of business: The home office must be your principal place of business, or a place where you regularly meet clients. If you have another office location, your home qualifies only if you use it substantially and regularly for administrative or management activities with no other fixed location for those activities.
Two Methods
Regular Method (Form 8829)
Calculate the business percentage of your home (square footage of office / total square footage) and apply it to actual home expenses:
- Mortgage interest or rent
- Real estate taxes
- Utilities (electricity, gas, water, internet)
- Home insurance
- Repairs and maintenance
- Depreciation of the home (allocated to business portion)
Simplified Method
Instead of tracking actual expenses, you can deduct $5 per square foot of home office space, up to a maximum of 300 square feet ($1,500 maximum deduction). This method requires no Form 8829 — you report the deduction directly on Schedule C, line 30.
Method Comparison
| Factor | Regular Method | Simplified Method |
|---|---|---|
| Max deduction | No cap | $1,500 |
| Record-keeping | Track all expenses | Just measure office area |
| Depreciation | Yes (recapture risk) | No |
| Form required | Form 8829 | None (Schedule C only) |
Key Lines on Form 8829
- Line 1: Total area of home (square feet).
- Line 2: Area used for business.
- Line 3: Business percentage (line 2 / line 1).
- Lines 9-21: Direct and indirect expenses allocated by business percentage.
- Line 36: Allowable home office deduction, which transfers to Schedule C.
