Aircraft ownership can create massive financial exposure long before the first flight.

In this episode of the Iron Bird Podcast, Dan Harris sits down with Thomas Alston, CEO of Aero & Marine Tax Professionals, to break down one of the most expensive and misunderstood risks in private aviation: sales and use tax.

Many aircraft buyers believe simple strategies, such as registering in another state, will protect them. In reality, that assumption is often wrong. States like California have become highly sophisticated in tracking aircraft usage, auditing ownership structures, and enforcing tax liability.

A single mistake in how an aircraft is purchased, where it is delivered, or how it is used during the first few months can result in millions of dollars in unexpected tax.

Thomas walks through the exact frameworks used to legally avoid tax, including the interstate commerce test, charter exemptions, and principal use rules. He also explains why most mistakes cannot be fixed after the fact and how even small documentation errors can trigger audits.

This episode is a clear reminder that aircraft tax strategy is not something to figure out later. It has to be structured correctly from the very beginning.

🔍 Why This Episode Matters

This episode highlights one of the most expensive blind spots in private aviation.

Most aircraft owners focus on performance, acquisition, and operations, but overlook tax structure until it is too late. By then, the liability is already locked in.

The reality is simple. If the aircraft is not structured correctly before delivery, there is often no way to fix it afterward.

For owners, operators, and advisors, understanding these rules can mean the difference between a clean transaction and a multi-million dollar mistake.
