For Airbnb and STR hosts who file Schedule C — substantial services, material participation, or active trade-or-business. Year-end Schedule C tax-prep workbook with SE tax preview + QBI safe harbor. Editable Excel. Most STR income lives on Schedule E. But a meaningful subset of hosts — the ones who provide substantial services (daily cleaning during stay, meals, transportation, concierge) or who materially participate in an active business — file Schedule C instead. That triggers self-employment tax (15.3%), but it ALSO unlocks bigger deductions: §179, hospitality-services expenses, vehicle qualified-business-use, full home office, retirement plan contributions. This workbook is the year-end tax-prep file for active STR hosts. It mirrors the Schedule E sibling (TAX-004) but adds the Schedule C-specific moves and reminders. WHAT’S INCLUDED 📋 Schedule C vs E Confirmation · The substantial-services test (cleaning during stay, meals, transportation) · Material participation thresholds (100+ / 750+ hours) · Material-participation hours log integration · Confirms you’re filing the right schedule before everything else 📋 Year-End Schedule C Wizard · Walks Schedule C Part I (income) and Part II (expenses) line-by-line · 26 expense categories pre-mapped to Schedule C line numbers · Multi-channel revenue rollup (Airbnb / VRBO / Booking.com / Direct) · Cost of goods sold worksheet (where applicable) 📋 SE Tax Preview · Net SE earnings × 92.35% × 15.3% · 50% above-the-line deduction calculated · Solo 401(k) / SEP IRA contribution math (active business unlocks these) 📋 Hospitality Services Worksheet · Substantial services that distinguish Sched C from E · Revenue per service category · Substantiation per category (per-stay logs, attendee notes) 📋 Vehicle Qualified-Business-Use Test · Form 4562 Part V listed-property tracking · 50% business-use threshold (drops below = §179 recapture) · Annual recap 📋 QBI Safe-Harbor Worksheet · Rev Proc 2019-38 — 250+ rental services hours · Service hours log per quarter · 20% QBI deduction eligibility flag 📋 Schedule C Summary Output · Line-by-line totals (Lines 1, 4, 7, 8-26, 28, 30-31) · Print-ready, ready for CPA or tax software
