Why Wisconsin punches above its weight in general aviation
Wisconsin is the annual home of EAA AirVenture Oshkosh, the largest fly-in gathering in the world, drawing tens of thousands of aircraft and hundreds of thousands of visitors to Wittman Regional Airport every summer. That single week says a lot about the state's aviation culture, but Wisconsin's general aviation footprint runs year round too, with a strong homebuilder and vintage community (EAA's own headquarters sits in Oshkosh) and active GA airports across Milwaukee, Madison, and the Fox Valley.
The rates above are our live national rates; Wisconsin residency neither helps nor hurts your pricing. What is Wisconsin specific is the tax picture below, including one exemption that goes further than most states are willing to go.
Sales tax, use tax, and property tax: the Wisconsin layer
Sales and use tax. Wisconsin's state sales and use tax rate is 5 percent, with counties able to add up to an additional 0.5 percent, so the combined rate on most aircraft purchases generally lands at or under 5.6 percent depending on the county where the aircraft is based. Wisconsin offers a fly-away exemption for nonresident buyers who remove the aircraft from the state (Wisconsin Administrative Code Tax 11.85(2) and Tax 11.84), and a separate exemption for aircraft used by certified or licensed interstate or foreign commerce carriers. No aircraft can be registered in Wisconsin without proof that sales tax was paid or that a valid exemption was claimed, so this is not a step you can defer until later.
A distinctive parts and labor exemption. Wisconsin exempts aircraft parts, maintenance, and repair labor on noncommercial aircraft from sales tax, a genuinely uncommon carve out that most states do not offer at all. If you are budgeting for ongoing maintenance after closing, this is worth confirming with your shop and factoring into your annual cost picture, not just the purchase itself.
This is orientation, not advice; Wisconsin aviation tax outcomes are fact specific. Engage a Wisconsin aviation tax advisor before closing.
The depreciation layer
Federal bonus depreciation is only half the tax picture; how Wisconsin treats the deduction is the other half. Wisconsin has not updated its conformity to the Internal Revenue Code since January 1, 2014, so it does not follow the federal 100 percent bonus depreciation rules enacted since then, meaning a state add-back is typically required. The bonus depreciation guide carries the full state-by-state conformity breakdown and the December 31 placed-in-service mechanics. Read it alongside this page before you commit to a closing date.
Compare against other states
The tax treatment above is specific to this state, but if you are comparing markets, financing across state lines, or want the full fly-away exemption rules in one place, see our aircraft sales tax by state guide for the state-by-state breakdown.

Interactive: payment and year-one depreciation, side by side
The two numbers every Wisconsin 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.

Illustrative only, not a loan offer and not tax advice. Bonus depreciation eligibility depends on qualified-business-use thresholds and listed-property rules; state conformity varies. See the
bonus depreciation guide for the December 31 placed-in-service mechanics and the state-by-state conformity table before you plan around these numbers.
What Wisconsin 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 Wisconsin you or the aircraft sit. Our title & escrow guide walks the sequence.
- Budget for parts and labor differently. Wisconsin's exemption on aircraft parts, maintenance, and repair labor for noncommercial aircraft is worth confirming with your maintenance shop; it can meaningfully change your ongoing ownership cost picture.
- AirVenture week changes local logistics. If you are hangaring or flying anywhere near Oshkosh in late July, expect a temporary flight restriction and heavy traffic during EAA AirVenture; plan deliveries and pre-buy inspections around it, not during it.

Wisconsin Aircraft Financing Questions
Do aircraft loan rates differ in Wisconsin?+
No, rates are set by aircraft type, credit profile, and loan structure, not by state. Wisconsin buyers see the same live pricing shown on this page. What is Wisconsin-specific is the tax treatment and the strength of the local market.
Does Wisconsin charge sales tax on aircraft purchases?+
Generally yes; Wisconsin's state sales and use tax rate is 5 percent, with counties able to add up to an additional 0.5 percent. A fly-away exemption is available for nonresident buyers who remove the aircraft from the state, and aircraft used in certified interstate or foreign commerce carrier service qualify for a separate exemption. No aircraft can be registered in Wisconsin without proof of tax paid or a valid exemption claimed. Confirm your specific situation with a Wisconsin aviation tax advisor before closing.
Does Wisconsin tax aircraft parts and maintenance labor?+
No, not for noncommercial aircraft; Wisconsin exempts aircraft parts, maintenance, and repair labor on noncommercial aircraft from sales tax. This is a genuinely uncommon exemption, and it is worth confirming with your maintenance shop so it is reflected correctly on your invoices.
Do I need to worry about EAA AirVenture if I'm buying or hangaring near Oshkosh?+
Only around timing. EAA AirVenture in late July brings a temporary flight restriction and heavy traffic to Wittman Regional Airport and the surrounding area for about a week. It doesn't affect your tax picture or financing, but it's worth scheduling deliveries, pre-buy inspections, and pickups around that week rather than during it.
Where does a Wisconsin aircraft closing actually happen?+
Through an FAA escrow agent in Oklahoma City, like every U.S. aircraft closing, deposit held in escrow, title searched, documents filed with the registry in sequence on funding day. You never have to leave Wisconsin.
Does Wisconsin conform to federal bonus depreciation?+
No; Wisconsin has not updated its conformity to the Internal Revenue Code since January 1, 2014, so it does not follow federal bonus depreciation rules enacted after that date, and a state add-back is typically required. See the bonus depreciation guide for the full state-by-state conformity table, and confirm current-year treatment with your CPA.
