Real estate tax
Passive activity
A real estate loss is only worth something if you are allowed to use it, and the code presumes you are not. The whole game is getting through one of Section 469's two doors.
A real estate loss is only worth something if you are allowed to use it. The tax code presumes you are not. By default, rental losses are passive, and passive losses can only offset passive income, so the depreciation you were counting on to shelter your salary or your business income just sits there, suspended, until you sell. The entire game is getting out of that default.
There are two doors, and these pages walk through both. Real estate professional status, which frees your losses entirely but demands a 750-hour test and the contemporaneous logs to survive the audit it invites. And the short-term-rental exception, the quieter door that reaches people who are not full-time in real estate at all. Material participation, grouping elections, the suspended-loss rules, each page names exactly what the test requires and what documentation makes the claim hold up. This is the highest-leverage area in real estate tax and the one the IRS looks at hardest. Both facts follow from the same thing: it is where the biggest deductions live.
