Form 8829

Use this skill when a sole proprietor or single-member LLC owner who files Schedule C wants to deduct actual expenses for business use of their home on IRS Form 8829, or wants to compare Form 8829 with the simplified home office method. Triggers on phrases like "fill out form 8829", "home office deduction regular method", "actual expense method home office", "form 8829 line 11 worksheet", "home office depreciation", "home office carryover", "daycare home office percentage", "schedule c line 30 form 8829". Do NOT use for W-2 employees working from home (not deductible; explain and stop), for partners or Schedule F farmers (Pub. 587 worksheet, not Form 8829), for renting part of a home to a tenant (use schedule-e), for the rest of Schedule C (use schedule-c), for depreciating business equipment (use form-4562), or for selling the home (use form-8949 / schedule-d, or form-4797 for a separate business structure).
