I'm a Missouri resident who bought an aircraft from a private seller in Missouri, had it repaired and stored here for a few months, and then moved it to Kansas where it's now hangared -- do I owe Missouri use tax on the purchase?

Plain-English summary

The Missouri Department of Revenue ruled that a Missouri resident who bought an aircraft from a private seller inside Missouri owed consumer's use tax on the purchase, even though the aircraft was later moved out of state to Kansas. The key fact was that the plane needed repairs, sat in Missouri for several months while it was fixed up, and then remained in Missouri for a couple more months after the repairs were finished before finally being flown to Kansas, where it is now hangared.

The Department's reasoning turns on how Missouri treats aircraft differently from cars and boats. Section 144.020.1(9), RSMo, imposes regular sales tax on motor vehicles, trailers, boats, and outboard motors -- but only those "purchased or acquired for use on the highways or waters of this state which are required to be registered under the laws" of Missouri. Aircraft don't fit that description: they aren't used on highways or waterways, and they aren't required to be titled under Missouri law. That means the sales-tax provision for vehicles and boats simply doesn't apply to an aircraft purchase.

Instead, the purchase falls under Missouri's separate use tax, imposed by Section 144.610.1, RSMo, on "storing, using or consuming" tangible personal property within the state (aircraft aren't on that section's list of excluded items, unlike cars, boats, and motorcycles). Because the aircraft was tangible personal property that was stored and used in Missouri for several months before being relocated, the Department concluded the purchase was subject to use tax.

What this means for you

Private aircraft buyers

If you buy an aircraft in Missouri and it sits in the state -- even temporarily, such as for repairs -- before you move it elsewhere, Missouri can treat that as taxable storage or use, triggering consumer's use tax on the purchase price. The fact that the aircraft ultimately ended up hangared out of state (in Kansas) did not exempt the purchase, because the taxable event was the storage and use that happened in Missouri first.

Aircraft sellers and brokers

This ruling involved a private-party sale, not a licensed dealer transaction, which is why use tax (rather than sales tax collected at point of sale) was the mechanism at issue. Anyone facilitating private aircraft sales in Missouri should be aware that the buyer may owe use tax directly to the state even when no dealer collects sales tax on the transaction.

Business owners and accountants advising aircraft purchasers

Don't assume aircraft get the same treatment as motor vehicles or boats under Missouri's sales tax. The motor-vehicle/boat carve-out in Section 144.020.1(9), RSMo, is narrow and tied to highway/water use and Missouri titling requirements -- aircraft meet neither condition. Plan for use tax exposure whenever an aircraft purchased in Missouri will be stored, repaired, or otherwise used in the state, even briefly, before leaving.

Common questions

Q: Why does it matter that the aircraft eventually left Missouri for Kansas?
A: It doesn't help the buyer here. Missouri's use tax applies to storing, using, or consuming tangible personal property within the state -- the several months the aircraft spent in Missouri (including time needed for repairs) were enough to trigger the tax, regardless of where the aircraft ended up afterward.

Q: Why isn't this purchase treated like buying a car or a boat in Missouri?
A: Section 144.020.1(9), RSMo, taxes motor vehicles, trailers, boats, and outboard motors only when they are acquired for use on Missouri's highways or waters and are required to be titled under Missouri law. Aircraft fail both parts of that test, so the sales-tax provision for vehicles and boats doesn't reach aircraft purchases -- which is why the Department instead applied the general use tax statute.

Q: Would the answer change if the aircraft had been flown out of Missouri immediately after purchase, with no repairs or storage?
A: The ruling doesn't address that scenario directly, but its reasoning depends on the aircraft having been stored and used in Missouri for several months. This ruling cannot be used to draw conclusions about a materially different fact pattern.

Q: Does this ruling apply to my aircraft purchase?
A: Not automatically. This letter ruling is binding on the Department only with respect to the specific Applicant who requested it, only for three years from its date, and only so long as the facts don't change and the underlying law isn't changed by the General Assembly or the courts. No other taxpayer can rely on it, though it shows how the Department reasons about similar facts.

Original ruling text

Dear Applicant:

This is a letter ruling issued by the Director of Revenue under Section 536.021.10, RSMo, and Missouri Code of State Regulations 12 CSR 10-1.020, in response to your letter dated May 5, 2026.

The facts presented in your letter ruling request and subsequent phone conversation on June 2, 2026, are summarized as follows:

Applicant is a Missouri resident who purchased an aircraft within the state of Missouri. The aircraft is hangered in Kansas. Applicant purchased the aircraft from a private seller in Missouri. The seller is a Missouri resident. Applicant registered the aircraft in the State of Missouri after purchase, and the aircraft remained in Missouri for a few months after purchase. At the time of purchase, the aircraft required maintenance and repairs to make it moveable. The aircraft remained in Missouri for a couple of months after repairs were complete, until finally being moved to Kansas where it remains hangered.

ISSUE :

Is Applicant’s purchase of an aircraft from a Missouri seller subject to consumer’s use tax?

RESPONSE :

Yes. Applicant’s purchase of an aircraft that was stored in Missouri for several months before being transferred out of the state is subject to consumer’s use tax.

Section 144.610.1, RSMo, provides:

A tax is imposed for the privilege of storing, using or consuming within this state any article of tangible personal property, excluding motor vehicles, trailers, motorcycles, mopeds, motortricycles, boats, and outboard motors required to be titled under the laws of the state of Missouri and subject to tax under subdivision (9) of subsection 1 of section 144.020[…]in an amount equivalent to the percentage imposed on the sales price in the sales tax law in section 144.020.

Section 144.020.1(9), RSMo, imposes a tax on:

[T]he purchase price[…]of new and used motor vehicles, trailers, boats, and outboard motors purchased or acquired for use on the highways or waters of this state which are required to be registered under the laws of the state of Missouri[.]

The purchase is not subject to sales tax under the motor vehicle and outboard motor statue in Section 144.020.1(9), RSMo, as aircraft are not purchased for use on the highways and waters of this state, and even if they were, aircraft are not required to be titled under the laws of Missouri. Therefore, because the aircraft is tangible personal property, and was stored and used in Missouri for several months prior to being relocated to Kansas, Applicant’s purchase of the aircraft is subject to consumer’s use tax.

This letter ruling is binding upon the Department of Revenue with respect to the Applicant for three (3) years from the date of this letter and is subject only to statutory changes by the General Assembly and to changes in the interpretation of law by the courts or administrative tribunals.   If a change occurs, the taxpayer who relies upon an outdated interpretation may be subject to additional taxes, interest and penalties, which may be imposed prospectively from the date of the change.   For this reason, the interpretation set forth above should be reviewed on a regular basis.   Please note that any change in or deviation from the facts as presented will render this ruling inapplicable.

Should additional information be needed, please contact Legal Counsel Gabriel Barnes, General Counsel's Office, Post Office Box 475, Jefferson City, Missouri 65105-0475, phone (573) 751-0961.
