Montana has no general state sales tax, so aircraft purchases avoid it entirely, though registered aircraft owe an annual fee in lieu of property tax. Financing an aircraft in Montana, done right.
Bozeman Yellowstone International Airport generates an estimated 2.2 billion dollars in annual economic impact, according to a 2026 Montana Department of Transportation and Zenith Economics study, roughly a third of the state's total aviation-related jobs and output. The airport supports about 2,000 direct and 11,000 indirect jobs, drives over 40 percent of visitor-by-air spending impact statewide, and is projected to handle 2.9 million passengers in 2026, making it by far Montana's busiest and most economically significant airport.
The rates above are our live national rates; Montana residency neither helps nor hurts your pricing. What is Montana specific is the tax picture below, where the absence of a general sales tax is the headline.
Montana has no general state sales tax. Montana is one of only five states without a general sales tax, alongside Alaska, Delaware, New Hampshire, and Oregon, so an aircraft purchase closed and registered in Montana owes no state sales or use tax at all.
Aircraft registered in Montana pay a fee in lieu of property tax instead. Any aircraft based or registered in Montana must register with the state within 30 days of acquisition and renew annually by March 1, paying a fee that varies by aircraft type and age in place of local personal property tax; older, smaller, and experimental aircraft pay a flat, modest fee under Montana Code Annotated 67-3-206.
This is orientation, not advice, and it is not a suggestion to register an aircraft in Montana that is actually based or used elsewhere. Your home state's use tax and property tax rules generally follow the aircraft's real base of operations, not its registration address, and several states, including California, actively audit out-of-state registrations that don't match where the aircraft is hangared and flown. Engage a Montana aviation tax advisor before closing.
Federal bonus depreciation is only half the tax picture; how Montana treats the deduction is the other half. The guidance here is genuinely mixed: older conformity summaries describe Montana as decoupled from federal bonus depreciation, but the most recent Montana Form 2 instructions indicate the state currently allows full pass-through of federal bonus depreciation, including the restored 100 percent bonus for property acquired after January 19, 2025, with no separate state addback required. Given that conflict, confirm the current-year treatment directly against the Form 2 instructions with your CPA before you plan around a specific number. 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.
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.
The two numbers every Montana 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.
