STR Tax Loophole: Hour Tracker The only app built specifically to help short-term rental investors document material participation hours and qualify for the STR tax loophole under IRS Reg 1.469-1T(e)(3)(ii). If you own a short-term rental with an average guest stay of 7 days or less, you may be able to reclassify your rental losses as non-passive and use them to offset your W-2 or active income. The tax savings can be substantial, but only if you can prove it. The IRS requires a contemporaneous log of every hour you spend managing your property. A spreadsheet won’t hold up. STR Tax Loophole gives you the documentation that will. ▸ AI SPEECH-TO-TEXT LOGGING Say what you did. The app transcribes your voice, identifies the property, category, and duration, and creates a timestamped entry automatically. Log an activity in under 30 seconds without typing a word. ▸ EVIDENCE UPLOADS Attach photos, receipts, invoices, and contractor documents directly to any entry. Build an audit-proof evidence trail that supports every hour you claim. The IRS values documentation with corroborating proof. This gives you exactly that. ▸ REAL-TIME DASHBOARD See your total hours, hours by property, hours by category, and progress toward the 100-hour threshold at a glance. Visual charts and stat cards update as you log, so you always know where you stand. ▸ MULTI-PROPERTY TRACKING Track hours across every rental you own. Each property gets its own activity history, category breakdown, and qualification status. See which properties are on track and which need attention. ▸ TEAM & SPOUSE TRACKING Add your spouse, property manager, cleaners, and contractors as team members. Track their hours alongside yours. A key requirement for qualification is proving that you personally spent more time on the rental than anyone else. This makes that comparison clear. ▸ CUSTOM CATEGORIES Organize your entries by activity type: guest communication, cleaning coordination, maintenance, bookkeeping, market research, renovation, and more. Categories align with IRS-recognized material participation activities so your log tells a clear story. ▸ CSV IMPORT & EXPORT Already tracking hours elsewhere? Import your existing data via CSV. Need a hard copy for your CPA or tax attorney? Export your complete log with one tap. Compatible with any spreadsheet or tax preparation workflow. ▸ CLOUD SYNC & BACKUP Your data syncs across iPhone, iPad, and desktop. Log an entry on your phone at the property and review your dashboard on your laptop at home. Daily cloud backups ensure nothing is ever lost. ▸ SECURE & PRIVATE Two-factor authentication, passkey support, and encrypted cloud storage protect your data. Your financial records stay private. ▸ WHY THIS MATTERS The STR tax loophole can save investors tens of thousands of dollars per year through bonus depreciation and cost segregation. But one audit without proper documentation can erase those savings entirely. CPAs and tax attorneys consistently say the same thing: the investors who qualify are the ones who keep detailed, contemporaneous logs. STR Tax Loophole was designed to make that effortless. ▸ WHO IT’S FOR Short-term rental owners on Airbnb, VRBO, or direct booking platforms. Real estate investors pursuing cost segregation and bonus depreciation strategies. Anyone whose CPA has told them they need to track their material participation hours.
