One of the most significant challenges for potential aircraft purchasers and owners is the complex web of state taxes and fees, which are levied in addition to federal sales and use tax schemes. Washington State has recently added a new and substantial cost consideration with the enactment of an unprecedented 10% “luxury tax” on noncommercial aircraft.
This new state-level tax is crucial, and Washington-based or Washington-connected entities must evaluate their tax exposure well before the effective date.
Overview of the New Levy
The Washington State Legislature has enacted a new 10% “luxury tax” that applies to noncommercial aircraft valued above $500,000. This tax applies in addition to existing state and local sales and use taxes (currently about 10.3% at Boeing Field).
The measure creates two entirely new levies:
-
Section 207 – Luxury Sales Tax: Applies to sales and leases of noncommercial aircraft.
-
Section 208 – Luxury Use Tax: Applies to aircraft brought into Washington and used by residents, with a credit for any tax previously paid under Section 207.
The law takes effect on April 1, 2026. It will apply even to aircraft already owned or leased if they are owned, leased, or based in Washington on that date.
Tax Rate and Base
The tax rate is 10% of the fair market value of the aircraft. For leases, the tax base is the aircraft’s fair market value at lease inception, not the rent stream. Entering into an arm’s-length financing lease will not avoid the tax.
Limited Exemption
Aircraft defined as “commercial airplanes” under RCW 83.32.550 are excluded. However, this definition was drafted for Boeing’s production-related incentives and is likely to apply only to commercial airliners.
Who is Affected?
The liability for the Luxury Use Tax is triggered differently for residents and nonresidents of Washington. The concept of “residency” may extend to out-of-state companies with Washington branches or employees, as well as seasonal residents renting summer homes.
The table below details the triggers for tax liability:
Illustrative Exposure Scenarios: * Aircraft based in Washington as of 4/1/2026 will likely be subject to the 10% tax, even if later relocated. * A single landing in Washington by a resident owner or lessee could trigger the tax. * A single landing by an out-of-state company that creates residency nexus (e.g., through a Washington branch or employee) could result in a 10% tax on the full value. * Leases to Washington Part 135 operators could trigger a 10% tax on the full aircraft value at lease commencement.
Potential Mitigation Strategies (Pre-Effective Date)
Aircraft owners and lessees with a connection to Washington should evaluate exposure and consider proactive mitigation strategies well before April 2026. These may include:
-
Re-basing or Re-leasing: Relocating the aircraft’s base or re-leasing the aircraft out-of-state before April 1, 2026, to avoid nexus.
-
Residency Review: Reviewing residency exposure for owners, entities, and related parties.
-
Lease Restructuring: Restructuring leases to manage the timing and jurisdiction of lease inception.
-
Documentation: Documenting commercial use (e.g., Part 135 charter) to preserve exemption arguments.
It should be noted that while the bill has passed both chambers, aviation industry groups are urging a line-item veto of Sections 207-208. If signed, the taxes would take effect April 1, 2026, but the Legislature could still revisit or repeal them in the 2026 session. Close monitoring of legislative and litigation developments is advised.
