Why aircraft tax planning starts before delivery

Most aircraft tax problems do not begin in an audit. They begin much earlier, when a buyer assumes the structure is simple enough to handle later.

In this Iron Bird podcast interview, Thomas Alston explains why that assumption can be brutally expensive. His warning is direct: aircraft owners can face millions of dollars in unexpected California tax if the purchase or delivery is handled incorrectly. In his view, the most dangerous mistake is waiting too long to get advice. By the time the aircraft is delivered to California, the damage may be done.

California’s own guidance backs up how serious this is. The state says aircraft purchases may be subject to use tax and that exemptions must be claimed and supported with proper documentation. For common carrier use, for example, the aircraft must be used in qualifying operations for more than 50 percent of the time during the first 12 consecutive months. For interstate or foreign commerce, the first functional use outside California and continuing qualifying use are critical.

The myth of “just register it somewhere else.”

One of the biggest bad assumptions Thomas calls out is the idea that registering the aircraft in another state somehow solves the California issue. He says owners hear versions of this all the time in hangar talk: put the plane in a different state, and California will never find you.

His point is simple. That is not a strategy. That is wishful thinking. California has become much more sophisticated in tracking aircraft activity, and once the state becomes aware of a transaction or usage pattern, the buyer may have to support a valid exemption or face the tax exposure. Thomas is especially blunt about people who rely on casual tax advice from the tarmac instead of experienced specialists.

That lines up with CDTFA’s position that the use tax can still apply when property purchased outside California is brought into the state, unless the purchaser qualifies for a specific exemption. The location of registration alone is not the controlling issue. The facts of delivery, first use, and subsequent use matter.

Why does the cost get so high so quickly?

The higher the aircraft value, the less room there is for sloppy planning. Thomas gives the obvious example: a large-cabin jet purchase can carry a tax exposure measured in millions. That is what makes “we’ll sort it out later” such a dangerous mindset.

He also points out something most owners do not think about until it is too late: once bad information is filed with the state, it may not be fixed. In the interview, he says one of the worst scenarios is when someone files on their own before calling his firm, because they may have already handed over facts or positions that cannot be cleanly reversed.

What owners should do instead?

Thomas’s practical advice is consistent throughout the conversation: get expert guidance before purchase, before delivery, and before filing anything with California.

Aero & Marine’s own site frames the service similarly, offering pre-purchase planning and exemption guidance specifically for California sales and use tax. The firm also offers free consultations, which aligns with Thomas’s repeated point that the cheapest mistake to avoid is the one you fix in advance.

The biggest aircraft tax mistake is not misunderstanding one rule. It assumes you can clean it up after the airplane is already delivered.

In Thomas Alston’s world, the real dividing line is simple: the people who call before delivery usually still have options. The people who call after a California delivery may not.
