An Aircraft Is Not a Tax Deduction. It's a Tax Strategy.
Where the Money Actually Moves
Acquisition Structure
Who owns the aircraft, how it's financed, and how it's used determine the tax outcome — and all three are set at closing. Bonus depreciation is worth the most to the owner who planned for it before the wire went out.
Business Use & Substantiation
The deduction survives on documentation, not intent. Personal use, related-party use, and the flight logs behind them are where these positions are won or lost.
Part 91 vs. Part 135
Leaseback into a charter certificate changes the depreciation profile, the excise exposure, and the risk picture. It's a tax decision wearing an operations costume.
Multi-State & Excise
Sales and use tax on acquisition, where the aircraft is based and hangared, and FET on charter are large, jurisdictional, and almost never modeled in advance.
The Deduction Is Decided Before the Wire Clears
Most aircraft purchases we see were structured by whoever was closest to the deal — the broker, the lender, sometimes the seller's counsel. The tax outcome is then whatever that structure happened to produce, and it's discovered the following spring by someone who wasn't consulted.
Ownership entity, financing, intended use, charter placement, and where it's based all move the number, and all of them are decided at once, on a timeline set by the transaction. That's the week to have your CPA in the room. Not the following March, when the only remaining job is reporting what you did.
Fleet Decisions Compound.
So Do Fleet Mistakes.
The second aircraft is rarely structured like the first, and the third rarely like the second — usually because each one was handled by whoever was available at the time. What accumulates is a fleet held across inconsistent entities with inconsistent depreciation postures and no one holding the whole picture.
The same is true of avionics upgrades, hangar and facility ownership, and the MRO equipment nobody thinks of as a tax decision until it's a large one. We look at the fleet as one structure, plan the acquisitions in sequence rather than one at a time, and file the return ourselves — because the return should be written by the people who know why it looks the way it does.
