Form 8829: Expenses for Business Use of Your Home
Definition: Form 8829 is the IRS form used by self-employed individuals, freelancers, or small business owners to calculate and claim a deduction for the business use of a home (home office). It computes allowable expenses like utilities, rent/mortgage interest, insurance, and depreciation based on the portion of the home used exclusively for business.
Why It Matters: The home office deduction can lower your taxable income significantly (up to $1,500 simplified or actual costs), but errors trigger audits, disallowed claims, or underreported income notices (CP2000). Strict rules apply: the space must be regular/exclusive business use (or daycare/inventory exceptions). If IRS challenges have reduced your refund or added debt, Omni Tax Help reviews your Form 8829, verifies measurements and eligibility, and amends via Schedule C to restore deductions—preventing penalties and maximizing relief.
Key Calculations:
- Simplified Method: $5 per sq ft (up to 300 sq ft = $1,500 max).
- Actual Expenses: Percentage of home (e.g., 200 sq ft / 2,000 sq ft = 10%) applied to indirect costs.
- Flows to Schedule C, Line 30.
What to Do Next:
- Measure dedicated space and track expenses.
- Attach to Form 1040/Schedule C (or use Pub 587).
- We audit-proof your claim and handle IRS inquiries.
