Aircraft Financing in Washington:

Why Washington is a serious general aviation state, not just a Boeing state

Washington runs 134 public-use airports across 37 of its 39 counties, and the state's aviation system supports an estimated 400,000-plus jobs statewide. Beyond the obvious Boeing/aerospace footprint around Puget Sound, the state has real GA depth — King County International (Boeing Field), Eastern Washington's agricultural aviation, and San Juan Islands fly-in access all support active ownership.

The rates above are our live national rates — Washington residency neither helps nor hurts your pricing. What is Washington-specific is the tax picture below, and one upcoming change is significant enough that any Washington-based buyer should know about it before they shop.

Washington has no state personal income tax, which simplifies the bonus-depreciation conversation considerably (see the callout below) — but it makes up ground with sales, use, and — starting April 2026 — a new luxury tax on higher-value aircraft.

Sales tax, use tax, and property tax — the Washington layer

Sales and use tax. Washington's state sales and use tax rate is 6.5 percent, and with local district taxes the combined rate can run up to roughly 10.6 percent in some cities. Use tax applies at the same combined rate, based on where the aircraft is permanently hangared, whenever sales tax wasn't collected. Nonresidents bringing an aircraft into Washington temporarily are exempt from use tax if present no more than 90 days in any continuous 12-month period; aircraft used more than half the time in interstate or foreign commerce for hire also qualify for an exemption. A new development buyers should know about: Washington enacted a 10 percent luxury tax on noncommercial aircraft sales and leases, applying to the value exceeding $500,000, effective April 1, 2026 — trade-ins do not reduce the taxable excess. Interstate/foreign-commerce-use aircraft, government aircraft, and otherwise-exempt nonresident aircraft are excluded.

Aircraft excise tax (in lieu of property tax). Washington does not assess ordinary county property tax on most aircraft. Instead, WSDOT's Aviation Division collects an annual excise tax at registration: a flat fee by aircraft type — for example $65 for single-engine piston, $115 for turboprop, $140 for turbojet, $90 for helicopter — prorated monthly. Aircraft operated by a company transporting people or property for compensation fall outside this excise regime and are instead subject to ordinary county personal property tax.

This is orientation, not advice — Washington aviation tax outcomes are fact-specific, and the new luxury tax is recent legislation. Engage a Washington aviation tax advisor before closing, especially on any purchase above $500,000.

Run the Washington Buyer's Numbers

Interactive: payment and year-one depreciation, side by side

The two numbers every Washington business buyer runs first: the monthly payment at today's rate, and what 100 percent bonus depreciation could be worth in year one. Both in one place — with the state layer linked below.

What Washington buyers should know

• Rates and terms are national. Same live pricing as the strip above — up to 20-year terms on certified pistons, 15 to 20 percent down for strong credit, soft-pull pre-qualification available.
• Closings are remote. Your closing runs through FAA escrow in Oklahoma City regardless of where in Washington you or the aircraft sit. Our title & escrow guide walks the sequence.
• Higher-value purchases should plan around April 2026. Washington's new 10 percent luxury tax on the value of noncommercial aircraft above $500,000 takes effect April 1, 2026 — if you're shopping above that threshold, talk to your advisor about timing before you sign.
• Business use is common here. Aerospace-adjacent and agricultural business flying support well-worn underwriting paths. Business Part 91 use finances at 80–85 percent LTV with terms up to 20 years; tell us the mission upfront.
