Arizona is one of the better states in the country to base an aircraft — clear skies, a dense general-aviation community, and a notably owner-friendly tax structure. But basing a plane here comes with two obligations owners routinely miss: you must register the aircraft with the State of Arizona, generally within 60 days, and you’ll pay an annual aircraft license tax on top of your FAA registration. An LLC is often the right way to hold the plane — for liability and privacy reasons — but it doesn’t change either of those state duties.

This guide is general information, not legal or tax advice. Aircraft ownership sits where FAA regulation, state tax, and insurance overlap; an aviation attorney and a CPA who knows aircraft are worth every dollar before you close.

Duty #1: register the aircraft with Arizona within 60 days

Most owners think “registration” means the FAA — the N-number on the tail. Arizona wants its own. Under Arizona law, an aircraft based in the state must be registered with the Arizona Department of Transportation (ADOT) Motor Vehicle Division (MVD) — its Aircraft Registration Unit — generally within 60 days of the aircraft entering the state, being purchased, or a change in ownership. This is a state filing entirely separate from your federal FAA registration, and it’s the hook that puts your plane on Arizona’s tax rolls.

A few things owners get wrong:

  • “Based” is about where the plane lives, not where you live. If the aircraft is habitually hangared or tied down at an Arizona airport, it’s based in Arizona — even if you, or the owning LLC, are somewhere else.
  • The clock is short — and missing it costs. Sixty days is not a lot of runway after a purchase.
  • It repeats. Registration and the license tax are annual, not one-and-done.

Duty #2: the aircraft license tax — and why it’s the good news

Here’s where Arizona earns its reputation. Instead of taxing aircraft as personal property at full market value the way California does, Arizona charges an annual aircraft license tax of one-half of one percent (0.5%) of the aircraft’s average value, with a $20 minimum, under A.R.S. § 28-8335. Two things make that favorable:

License tax rate
0.5%
of average value
Minimum tax
$20
per year
Special aircraft
$20 flat
antique, classic, homebuilt...
Valuation cap
CPI
year-over-year increase
  • The value isn’t your purchase price. It’s the average fair market value for the make, model, and year of aircraft — Arizona ignores condition, equipment, and what you actually paid.
  • Increases are capped. By statute, the average-value figure can’t rise year-over-year by more than the change in the consumer price index — so the assessment tracks the model’s depreciation rather than a hot resale market, and the number you pay generally shrinks over the life of the plane.

Put the two states side by side and the gap is stark:

Ongoing state tax on a based aircraftArizonaCalifornia
What’s taxedAnnual license tax on average valueCounty property tax on full market value
Headline rate0.5% of average value ($20 min)≈1% + local add-ons
Valuation trendFollows model depreciation; CPI-cappedReassessed to market every Jan 1
Rough bill on a $250k plane≈$1,250/yr, falling≈$2,500+/yr, tracking value

Some categories pay a flat amount instead of the percentage tax: antique, classic, warbird, glider, experimental, and homebuilt aircraft each pay $20 a year under A.R.S. § 28-8339 — but you have to apply for it annually. Nonresident aircraft based in Arizona for only part of the year pay on a sliding scale: nothing for 90 days or fewer, 0.1% for 91–209 days, and the full 0.5% beyond that. The exact valuation for your specific tail lives with ADOT MVD; confirm your aircraft’s assessed value before you budget, because 0.5% is the fixed statutory rate but the average-value figure it’s applied to is theirs to set.

The Scottsdale / Deer Valley bizjet scene

Arizona’s tax structure is a big reason the Phoenix metro has become a genuine business-jet hub. Three ramps do most of the heavy lifting:

Scottsdale (KSDL)

Scottsdale Airport is the marquee bizjet field — a single runway, a wall of jet cards and fractional tails, and a based fleet that skews heavily toward light and midsize jets flown by owners and closely held companies. If you’re buying a Phenom, a Citation, or a PC-24 to base in the Valley, KSDL is the default, and the LLC-plus-management-company structure is the norm on that ramp.

Deer Valley (KDVT)

One of the busiest general-aviation airports in the country by operations, Deer Valley is training-and-piston heavy but carries a large based fleet of everything from Cirrus SR22s to turboprops. It’s the field where a first-time owner’s SR22 or TBM most often lands — and where the 60-day ADOT registration deadline most often gets missed, because buyers are focused on the FAA paperwork.

Mesa Gateway (KIWA / IWA)

Phoenix-Mesa Gateway anchors the East Valley with long runways, MRO capacity, and room for larger-cabin aircraft. It’s increasingly where heavier bizjets and charter fleets sit, and where the flight-department-company questions below get real, because the operations are more likely to involve paid crews and cost-sharing among members.

The FAA layer: citizenship and the LLC

State registration is only half the paperwork. To register with the FAA, the owner must be a U.S. citizen, resident alien, or a qualifying U.S.-citizen entity. An LLC qualifies as a U.S. citizen under 14 CFR 47.2 automatically when every member is a U.S. citizen. If any member isn’t, the LLC can still qualify only if its president and at least two-thirds of its managing officers are U.S. citizens and U.S. citizens own or control at least 75% of the voting interest — and the FAA requires a separate LLC statement in support of registration identifying every member and explaining how the entity qualifies, filed alongside the AC Form 8050-1 application.

The flight department company trap

This is the single most common — and most expensive — mistake in aircraft LLCs, and it applies in Arizona with full force.

The FAA calls it the flight department company problem. When an LLC’s only business is owning and operating an aircraft for its own members, the entity’s business is transportation by air. Under 14 CFR 119.1, any money flowing to that entity in connection with flights — even routine cost reimbursements or capital contributions from its own members — can count as compensation. Compensation plus carriage equals a commercial operation, and a commercial operation requires an air carrier or commercial operator certificate the LLC almost certainly doesn’t hold.

Aviation attorneys structure around it with tools like a dry lease from the LLC to the person actually operating the flight, or the cost-sharing options under 14 CFR 91.501 for larger and turbojet aircraft. The specific fix depends on your aircraft and how it’ll be flown. The one universal rule: paper the operations with an aviation attorney before the first flight, not after the first ramp check.

So where should the LLC be formed?

Two separate questions get tangled here, so pull them apart:

  1. Where the aircraft is registered and taxed — that’s Arizona, full stop, if the plane is based here. The 60-day ADOT registration and the license tax follow the hangar no matter where the entity was born.
  2. Where the holding LLC is formed — that’s a genuine choice, and it’s about the entity’s liability, privacy, and annual cost, not the plane’s tax.

The practical playbook

  1. 1

    Fix the ownership structure first

    Solo, partnership, or LLC — work through the general aircraft-LLC tradeoffs and the FAA citizenship math above before you sign a purchase agreement.

  2. 2

    Form the holding LLC where it makes structural sense

    Arizona for simplicity, Wyoming for privacy, Delaware for multi-partner deals. FilingDesk files all three today for $99 flat plus the state fee, with a human specialist reviewing every filing before it goes out.

  3. 3

    Register the plane with ADOT MVD within 60 days

    Once the aircraft is based in Arizona, budget the annual license tax — 0.5% of average value, $20 minimum — and put the 60-day deadline in your calendar the day you take delivery.

  4. 4

    Complete FAA registration

    File the LLC statement in support of registration alongside AC Form 8050-1 if an entity owns the aircraft.

  5. 5

    Paper the operations

    Insurance in the LLC’s name, plus a dry lease or 91.501 arrangement that keeps you clear of the flight department company trap.

Frequently asked questions

Do I have to register my aircraft with the State of Arizona?
Yes. If your aircraft is based in Arizona, state law requires you to register it with the Arizona Department of Transportation's Motor Vehicle Division (MVD) — specifically the Aircraft Registration Unit — generally within 60 days of bringing it into the state or acquiring it. This is separate from your FAA registration: Arizona wants its own record and its own annual license tax. Miss the 60-day window and a penalty accrues ($25 the first month, $5 each month after). A plane hangared in Arizona is squarely in scope.
How much is Arizona's aircraft license tax?
Arizona levies an annual aircraft license tax of one-half of one percent (0.5%) of the aircraft's average fair market value, with a $20 minimum. The value used is the average fair market value for that make, model, and year — purchase price and condition are ignored — and any year-over-year increase is capped at the change in the consumer price index, so the figure tracks the model's depreciation rather than a rising market. Antique, classic, warbird, glider, experimental, and homebuilt aircraft instead pay a flat $20. That is dramatically cheaper than California's roughly 1% annual property tax on full market value.
Does forming a Wyoming or Delaware LLC avoid Arizona's aircraft taxes?
No. Arizona's registration requirement and license tax follow where the aircraft is based, not where the LLC was formed. A Wyoming LLC that hangars its jet at Scottsdale still has to register the plane with ADOT within 60 days and pay the Arizona license tax. Out-of-state holding LLCs are legitimate for liability separation and privacy — they just don't change the state aircraft tax result.
Can an LLC register my aircraft with the FAA?
Yes, if the LLC qualifies as a U.S. citizen under 14 CFR 47.2. When every member is a U.S. citizen, the LLC qualifies automatically. Otherwise its president and at least two-thirds of its managing officers must be U.S. citizens, and U.S. citizens must own or control at least 75% of the voting interest. The FAA also requires a separate LLC statement in support of registration identifying every member and how the entity qualifies, filed with the AC Form 8050-1 application.
What is the flight department company trap?
It's the FAA's term for a sole-purpose entity whose only business is owning and operating an aircraft for its own members. Because the entity's business is transportation by air, money flowing to it for flights — even cost reimbursements from members — can count as compensation, turning private flights into commercial operations that require an air carrier certificate the LLC doesn't hold. Penalties are assessed per flight. An aviation attorney structures around it with a dry lease.
Where should I form the LLC that owns my Arizona-based aircraft?
You can form the holding LLC in Arizona, or in a privacy-and-cost-friendly state like Wyoming or Delaware if that fits your structure. The choice affects the entity's formation and annual costs — not the Arizona registration or license tax, which follow the plane regardless. FilingDesk files Wyoming, Delaware, and Florida today for $99 flat plus the state fee; the Arizona aircraft filings stay with you and your aviation pros.
Which Arizona airport should I base my aircraft at — Scottsdale, Deer Valley, or Mesa Gateway?
It depends on the aircraft and how it's operated, not on registration or tax rules — those are the same statewide. Scottsdale (KSDL) is the marquee bizjet field for light and midsize jets under an LLC-plus-management-company structure. Deer Valley (KDVT) is training-and-piston heavy with a large based fleet from Cirrus SR22s to turboprops, and it's where first-time owners most often land — and most often miss the 60-day ADOT deadline. Mesa Gateway (KIWA) has longer runways and MRO capacity for larger-cabin aircraft and charter fleets, where the flight-department-company questions are most likely to come up.
How do aviation attorneys avoid the flight department company problem?
Common tools include a dry lease from the LLC to the person actually operating the flight, or the cost-sharing options under 14 CFR 91.501 for larger and turbojet aircraft. The right fix depends on the aircraft and how it's flown, which is why the operations need to be papered with an aviation attorney before the first flight — not after the first ramp check.
