States Scrutinizing Aircraft Sales and Lease Transactions

Aircraft Transactions Face a Fragmented State Tax Landscape

State sales and use tax treatment of aircraft transactions continues to evolve, creating a complex and increasingly fragmented landscape for taxpayers. An aircraft is uniquely impacted by state tax rules due to its mobility and multi-state use, which can trigger tax obligations across jurisdictions at different points in time.

In general, most states impose sales or use tax on aircraft purchases in the state unless a specific exemption applies, such as interstate commerce use, resale through leasing structures or fly-away provisions. Fly-away rules allow certain non-resident buyers to purchase an aircraft in the state without paying that state’s sales tax if the aircraft is removed from the state within a set time frame after purchase.

At the same time, state auditors are placing greater emphasis on enforcing use tax when an aircraft is purchased in low- or no-tax jurisdictions and subsequently brought into other states for storage or operational use. As a result, it is generally not possible to avoid tax by purchasing in a no-tax jurisdiction and subsequently basing or using the aircraft in another state, absent a valid exemption or properly structured leasing arrangement.

Recent State Tax Developments Affecting Aircraft Sales and Leases

Recent legislative changes demonstrate how states have varied rules and guidance regarding the purchase or lease of an aircraft.

Washington state’s proposed 10% luxury tax on certain noncommercial aircraft was ultimately reversed before implementation due to industry opposition and concerns about economic impact.

Arkansas clarified its exemption framework by enacting House Bill 1807, effective October 1, 2025. The law allows qualifying aircraft dealers to purchase aircraft exempt from resale and temporarily use those aircraft in rental or charter service without incurring sales or use tax. The exemption applies for up to one year from the date of purchase.

Meanwhile, some states, such as California and Massachusetts, provide exemptions for interstate and foreign commerce for aircraft used primarily for those purposes. The breadth of the exemption depends on the extent of interstate use and the degree of residency within the state.

Leasing and MRO Activities Remain Key Audit Focus Areas

Leasing an aircraft and maintenance, repair and overhaul (MRO) activities remain key areas of focus for both taxpayers and taxing authorities.

Leasing, as opposed to purchasing an aircraft, continues to be a primary planning tool for deferring the sales tax on acquisition. This allows the tax to be paid over the term of the rental agreement rather than upfront when the property is leased. However, states are increasingly scrutinizing whether lease structures have sufficient economic substance.

Similarly, MRO arrangements often involve bundled services, parts procurement and multi-state activity, making taxability depend on how transactions are structured and documented. Common audit focus areas include reviewing lease structures for economic substance, examining resale certificate use, verifying the proper classification of management fees and evaluating whether parts and labor charges are properly separated on invoices.

Furthermore, state auditors are scrutinizing aircraft leases to determine whether they are true operating leases, in which the lessor retains ownership risk, or merely disguised leases in which the lessee acts as the economic owner.

Storage, Repairs and Documentation Can Create Additional Exposure

In addition, storage, repair and maintenance activities introduce further complexity and represent frequent audit triggers. The location where an aircraft is stored or primarily based can create use tax exposure, with states relying on documentation such as flight logs and hangar records to determine liability.

Audit activity often focuses on an aircraft brought into a state shortly after purchase, inconsistencies in flight logs, improper classification of parts purchased and bundled repair invoices where tax may be applied to the full charge.

States also differ on whether sales tax is imposed on aircraft repairs, particularly regarding the taxability of labor versus parts, making proper invoice segregation critical.

Thus, the choice of where to have those repairs performed can also impact the cost of maintaining the aircraft.

Key Takeaways for Aircraft Owners and Operators

As states continue to expand enforcement and refine their rules, taxpayers must ensure that their acquisition, leasing and operational practices align with applicable state requirements and are supported by consistent documentation to mitigate audit risk. Because state tax treatment can vary significantly depending on how and where an aircraft is purchased, leased, stored and operated, regular review of these activities can help identify potential exposure before it becomes an audit issue.

Aircraft transactions often involve complex sales and use tax considerations that vary significantly by state.
