Aircraft Sales Tax by State: Where to Register and Why It Matters

Which states charge zero sales tax on aircraft?

Five states impose no general sales tax that reaches an aircraft purchase: Montana, Delaware, Oregon, New Hampshire, and Alaska. South Dakota deserves an asterisk — it has a 4.5% state sales tax but exempts aircraft from sales and use tax under SDCL 10-46-17.2 when registered with the South Dakota Department of Transportation Aeronautics Division, replacing it with a flat aircraft registration fee. That structural design, combined with no personal property tax on aircraft, is why South Dakota has quietly become a closing jurisdiction rival to Delaware for owners who want a clean U.S. registration without Montana's documentation theater.

The zero-tax states do not erase the buyer's home-state use tax obligation. A buyer who closes in Montana through a Montana LLC but bases the aircraft in Texas, California, or Florida still owes that home state's use tax at the in-state rate unless an exemption applies. The closing structure manages the seller's collection duty; the home-base state cares only about where the aircraft is hangared and flown.

How does use tax actually catch buyers who close out of state?

Use tax is the mirror of sales tax, owed by the purchaser when an out-of-state closing avoids the sales tax that would have been due in the state of use. Every state with a sales tax has a parallel use tax at the same rate, and revenue departments enforce it aggressively against aircraft because the FAA registry and state hangar leases are public records.

California's Department of Tax and Fee Administration runs an aircraft program that cross-references N-number registrations against California-based hangars and pilots, and routinely issues use-tax assessments running into six and seven figures. Florida, Texas, Washington, and New York operate similar programs. The standard audit triggers are a Florida hangar lease, a Texas mailing address on the FAA registration, or a flight-tracking history showing the aircraft based in-state for more than the threshold number of days (often 60 or 90 in the first six to twelve months after purchase).

What is the fly-away exemption and where does it apply?

A fly-away exemption lets a non-resident buyer close a sale in a high-tax state without paying that state's sales tax, provided the aircraft is removed from the state within a defined window and is not based there afterward. Roughly two dozen states offer some version, including Texas, Florida, Tennessee, Arizona, Kansas, and Ohio.

The mechanics vary. Texas requires the aircraft leave the state within 10 days of sale and not return for use in the state, documented on a properly executed exemption certificate. Florida's exemption under Fla. Stat. §212.05(1)(a)2 requires removal within 10 days (or 20 days if undergoing modification or repair) and a sworn affidavit. Tennessee allows a 15-day window. These exemptions are documentation-heavy: missed paperwork, a return trip too soon, or a logbook that shows the aircraft back at the closing-state FBO before the holding period ends will collapse the exemption and trigger full tax plus penalties.

How do Montana and Delaware LLC structures actually work?

The Montana LLC structure puts title in a Montana limited liability company that has no Montana sales or use tax exposure, with the aircraft registered to the LLC at the FAA. Delaware uses the same logic — a Delaware LLC or statutory trust holds title. Both states are friendly because neither imposes sales tax on the transaction and neither will assess use tax based merely on the entity's domicile.

The structure works when the aircraft is genuinely itinerant or based in a state that recognizes the LLC's separate existence and offers its own exemption. The structure fails when the aircraft is hangared full-time in a state like California, which under Revenue and Taxation Code §6248 and longstanding CDTFA practice will look through a single-purpose LLC and assess use tax on the beneficial owner. California's "test period" doctrine — requiring the aircraft to be used predominantly outside California for the first six or twelve months — is the practical hurdle, not the LLC paperwork.

Owners who structure through Montana or Delaware and base the aircraft in a sales-tax state without separately qualifying for a home-state exemption are buying litigation, not tax savings.

What about casual-sale and occasional-sale exemptions?

A handful of states exempt aircraft sold between private parties from sales tax under casual-sale or occasional-sale rules, but most have closed this loophole for aircraft specifically. Georgia's casual-sale exemption under O.C.G.A. §48-8-3(8) historically applied to aircraft sold by a non-dealer, and a few states (notably Arkansas in limited circumstances) preserve narrow versions. New York, California, Texas, and Florida all carve aircraft out of any general casual-sale relief — the legislatures recognized that high-dollar private aircraft transfers were the exemption's largest revenue leak and closed it.

Verify the current statute before relying on a casual-sale position. The exemption is one of the most-litigated areas of aircraft state tax and the case law swings.

Which states impose ongoing personal property tax on aircraft?

Roughly 20 states impose an annual personal property tax on aircraft, separate from the one-time sales or use tax. California assesses aircraft at fair market value annually through the county assessor (typical effective rates around 1.0–1.2%). Texas, Virginia, Kentucky, Missouri, Georgia, North Carolina, and South Carolina all run annual aircraft tax programs through county or local assessors, with rates ranging from 0.3% to over 2% of assessed value.

A $20 million jet based in Los Angeles County faces roughly $200,000–$240,000 annually in property tax on top of any use tax. A buyer who solves the sales tax through a Nevada or South Dakota structure but bases in California has not actually solved anything — the annual property tax dwarfs the closing tax over a five-year hold.

What documentation does the audit actually require?

State revenue departments demand the bill of sale, FAA registration, hangar agreements, fuel receipts, pilot logbooks, flight tracking data, and corporate records of the holding entity. California, Florida, and Washington routinely subpoena ARINC, FlightAware, or ADS-B data to reconstruct the aircraft's location history during the test period.

Contemporaneous records win audits. Reconstructed logs, after-the-fact business purpose memos, and gaps in hangar invoices lose them. Owners structuring around state tax should treat the first 12 to 24 months of ownership as a documentation discipline, not a paperwork afterthought — the assessment, if it comes, will arrive 18 to 36 months after closing and the records produced then will decide a seven-figure question.
