Bringing an aircraft into the United States can attach customs duty, federal excise tax and a state use bill — or, structured correctly, very little. The difference is planning.
A buyer settles on an aircraft abroad and assumes the price is the cost. Importing it into the United States can add customs duty, a federal excise charge on the transport that follows, and a state use tax that turns on where the jet is based — or, with the right structure and exemptions, comparatively little. The figures below are typical ranges to frame the decision; rates and reliefs change, so engage qualified aviation tax counsel before you commit.
The first question on importing an aircraft is customs duty, and here the news is often better than buyers expect. The United States is a signatory to the WTO Agreement on Trade in Civil Aircraft, under which qualifying civil aircraft and many of their parts enter duty-free. A great many business jets imported into the US therefore attract no customs duty at all, provided they meet the civil-aircraft criteria and are correctly entered.
That said, ‘often duty-free’ is not ‘always duty-free’. Eligibility depends on the aircraft's classification, its origin and the specific tariff provisions in force at the time of entry — and the broader tariff landscape can shift with trade policy. The entry must be made correctly, with the right Harmonized Tariff Schedule classification and supporting documentation, for the exemption to hold. The practical points are these:
Duty is usually the smallest part of the picture. The taxes that follow the import — excise and state use — are where the real money sits.
The federal excise tax is widely misunderstood, so be precise about what it is. FET of 7.5 percent is not a tax on importing or buying an aircraft. It is a tax on the commercial transportation of persons by air — it attaches to amounts paid for taxable air transportation, the kind of charge that arises when you charter a jet or buy carriage on one. A domestic-segment fee per flight segment applies on top of the percentage charge.
The distinction matters enormously for how you intend to use the aircraft. If you own and operate a jet purely for your own non-commercial use, the 7.5 percent transportation FET is generally not in point. If, however, you place the aircraft on a charter certificate and sell its seats or its hours — a common way to offset ownership cost — then FET typically applies to the charter revenue, and the line between non-taxable owner flights and taxable commercial carriage becomes a compliance question in its own right. Aircraft management arrangements have their own FET treatment, which has shifted with regulation and guidance over the years. If charter income is part of your plan, model the FET consequence before you sign the management agreement, not after the first audit.
For most US buyers the largest single tax exposure on an aircraft is neither duty nor FET but state sales and use tax, and it turns almost entirely on where the aircraft is based and used. Rates commonly fall in the region of 4 to 8 percent of the aircraft's value — on a $20 million jet that is potentially $800,000 to $1.6 million — and it is owed to the state where the jet is hangared and operated, regardless of where the purchase closed.
This is why aircraft-friendly states matter. Several offer well-established exemptions — for aircraft used in interstate commerce, for sale-for-resale or leasing structures, for a fly-away on out-of-state delivery, or for occasional-sale treatment — that can lawfully reduce or remove the use-tax charge when the conditions are met and documented. The conditions are specific and the documentation strict; an exemption claimed but not properly evidenced is an assessment waiting to happen. The state in which you base the aircraft is therefore a deliberate planning decision with a seven-figure price tag, and it should be settled with state-specific advice before the aircraft arrives.
Maximum take-off weight — MTOW — is a deceptively important number, because several regulatory and fiscal thresholds in US aviation hinge on it rather than on the aircraft's price or glamour. Weight determines which operating rules apply, which fees and programmes are engaged, and, in some contexts, how charges are calculated.
| MTOW band | Typical aircraft | Why the threshold matters |
|---|---|---|
| Up to 12,500 lb | Light jets, turboprops | Lighter regulatory and certification burden |
| 12,500–41,000 lb | Midsize to super-midsize jets | Crosses key operating-rule and weight thresholds |
| Over 41,000 lb | Large-cabin, ultra-long-range | Engages additional fees, programmes and oversight |
The point for a buyer is not to memorise the bands but to understand that MTOW is a hidden variable in the cost of operating, not merely owning, the aircraft. Registration fees, certain user charges, and the regulatory regime under which crew and maintenance are managed can all step with weight. Two jets at a similar price can carry different ongoing fiscal and regulatory burdens because they sit either side of a threshold. Factor MTOW into the total cost of ownership, not just the purchase decision.
How you hold and import the aircraft is as consequential as which aircraft you choose. Buyers rarely take title personally; they import and own through a structure designed to address liability, financing, confidentiality and tax. The common patterns each carry trade-offs that must be weighed against your actual flying and any charter intentions.
None of these is a loophole; each is a recognised structure with conditions, reporting and substance requirements attached. Misuse — claiming a commercial exemption while flying the jet purely privately, for instance — converts a saving into an exposure. The structure must be built to match how the aircraft will genuinely be used, by advisers who specialise in this field.
The recurring failure is to buy first and structure afterwards. By the time an aircraft has been bought, imported and based, many of the lawful planning options — the fly-away exemption, the correct entity, the optimal base state, the clean FET position — have already been foreclosed. The right sequence is the reverse: settle how and where the aircraft will be used and based, model duty, FET and state use tax across the realistic options, build the ownership and import structure to fit, then complete the purchase and the entry in that order.
Done this way, an import that might have carried a six- or seven-figure tax surprise becomes a planned, documented and defensible position. Customs entry is filed correctly to preserve the civil-aircraft duty exemption; the base state and any use-tax exemption are chosen and evidenced in advance; the FET treatment follows a clear decision about charter; and MTOW is factored into the running cost. The rules vary by state and shift with federal policy, so treat this page as general education and put qualified aviation tax and customs counsel on the file before you commit capital.
We do not sell aircraft and we do not improvise tax positions. Through the Obsidian Helm Marketplace we source and vet jets, operators and import structures on your behalf, and coordinate the acquisition — customs entry, base-state use tax, FET treatment and the ownership entity — alongside the qualified aviation tax and customs advisers your transaction requires, under NDA throughout. We negotiate terms with vetted partners, model the full landed cost before any contract is presented, and remain your single point of contact. Request a private introduction to begin.

Often not. The United States is party to the WTO Agreement on Trade in Civil Aircraft, under which qualifying civil aircraft generally enter duty-free, so many business jets attract no customs duty. The exemption depends on correct classification and entry and on the tariff rules in force at the time, so confirm the live position for your aircraft rather than assuming it applies.
No. The 7.5 percent FET is a tax on commercial air transportation — amounts paid for taxable carriage, such as charter — not on purchasing or importing an aircraft. If you own and fly a jet purely for your own non-commercial use it is generally not in point. If you place it on a charter certificate and sell its hours, FET typically applies to that revenue, so plan the treatment before signing a management or charter agreement.
For most buyers it is state sales and use tax, commonly around 4 to 8 percent of the aircraft's value, owed to the state where the jet is hangared and used. On a $20 million aircraft that can be well over a million dollars. Several states offer exemptions — interstate commerce, fly-away delivery, leasing structures — that can lawfully reduce it when the conditions are met and properly documented.
MTOW determines which operating rules apply and can engage different fees, programmes and regulatory oversight. Several thresholds in US aviation hinge on weight rather than price, so two similarly priced jets either side of a band can carry different ongoing costs. Factor MTOW into total cost of ownership, not just the purchase decision.
Buyers rarely do. Aircraft are usually held through a structure — commonly a single-purpose entity or a leasing arrangement — to address liability, financing, confidentiality and tax, including state use-tax exemptions in some jurisdictions. The right structure depends on how the aircraft will genuinely be used and must be built to match that use. This is specialist ground; take qualified aviation tax advice before deciding.
