A worked exampleThe airplane write-off, with the part nobody mentions.
You buy a $400,000 airplane and put it on leaseback with a flight school. Bonus depreciation is permanent again, so the pitch is simple: deduct the whole thing in year one.
The deduction is real. The problem is what you can use it against.
Aircraft rental is a rental activity, and rental activities are passive under §469. Passive losses offset passive income. If your income is wages, or a business you actively run, there's nothing there to offset. So the $400,000 doesn't disappear. It sits suspended, sometimes for years, until you either generate passive income or dispose of the aircraft.
Then §280F arrives. Listed property has to clear more than 50% qualified business use in the first year to get bonus depreciation at all, and use by a related party or a 5% owner generally doesn't count toward that test. Miss it in a later year and you switch to straight-line and recapture the excess as ordinary income.
None of this makes a leaseback a bad idea. It makes it a structuring question with a right answer and several expensive wrong ones, and the answer depends on facts that exist before you sign.
General information using current law, simplified. Your facts change the answer.
