Year one is the year cost segregation pays the most. A $400K depreciable basis can throw off $80K–$120K in first-year deductions. But none of it sticks if you can't prove material participation. DeductFlow tracks every expense, mile, and active hour from day one, so the cost seg study actually lands.
Learn how cost segregation works →If you skipped cost seg in year one, Form 3115 lets you catch up every missed deduction in a single return, without amending prior years. The window doesn't close until you sell. DeductFlow runs the daily records every CPA needs to make the Form 3115 filing stick.
Learn how Form 3115 catchup works →I bought my first Airbnb in 2025. Soon after, I asked my CPA how to track my deductions and he sent me a spreadsheet. Then I used one app for mileage, another for active hours, and a notes file for receipts. If I kept going like that, by April I'd be reconstructing the whole year from memory.
I built DeductFlow because I was tired of juggling four tools to track one property. Now you have one place for every expense, mile, and active hour. And one PDF for your CPA at tax time.
If you want to maximize every Airbnb deduction and you're tired of juggling spreadsheets and multiple apps, DeductFlow was built for you.
The mobile companion is a lightweight tracker built for when you're at the property. Log participation hours, record a trip, or snap an expense receipt. No app store. Just open it in your browser.
One PDF. Every deduction organized exactly how a CPA wants to see it: by IRS category, with mileage logs, active hours, and the cost-seg study summarized in a single P&L. No reconstruction.
