Make your home office pay you back. Home office deduction calculator for Airbnb and STR hosts. Simplified $5/sqft vs actual method, side-by-side. Pub 587. Editable Excel. Your laundry room handles cleaner pickups, supply staging, and your iPad while you manage bookings. Your dining table is where you reconcile receipts and chase contractor W-9s. There’s a dedicated corner of your office that exists only for managing the STR. The IRS allows a home office deduction for any space used regularly + exclusively for the business — and most STR hosts qualify. Most don’t take it because the math feels intimidating and they’re worried about audit risk. This workbook handles both. Two methods side-by-side, audit-defense documentation built in, ready for Form 8829 (Schedule C) or Schedule E line allocation. WHAT’S INCLUDED 📋 Two-Method Comparison (the headline) · Simplified method: $5/sqft up to 300 sqft = $1,500 cap · Actual method: % of home expenses (utilities, insurance, depreciation, mortgage interest) · Side-by-side dollar comparison — pick whichever’s higher 📋 Home Office Inventory · Dedicated room or partition (regularly + exclusively used) · Square footage measurement · Photos checklist for audit defense 📋 Actual-Method Worksheet · % of home = office sqft / total sqft · Indirect expenses: utilities, homeowner’s insurance, mortgage interest, property tax, repairs · Direct expenses: paint, supplies for office only (100% deductible) · Auto-totals at the IRS rate 📋 Schedule E vs Schedule C Routing · Schedule E filers: deduction goes on Line 19 (Other) with substantiation · Schedule C filers: Form 8829 attached to Schedule C · Decision footnote based on your Settings tab classification 📋 Audit-Defense Documentation · Regular + exclusive use checklist (Pub 587) · “Principal place of business” test · Photo evidence checklist (room dimensions, equipment, no-personal-use proof)
