If my out-of-state online retail company uses a Missouri third-party logistics (3PL) warehouse to fulfill orders, do I owe Missouri sales tax or use tax, and does it depend on where the order ships?

Plain-English summary

The Missouri Department of Revenue ruled on how sales and use tax apply to an out-of-state online retailer that uses a Missouri-based third-party logistics (3PL) company to store and fulfill orders. The Applicant was a California company selling personal property at retail, registered in Missouri for use tax but not sales tax, shipping orders both into and out of Missouri.

The Department's answer turned entirely on two things: where the goods physically are when the order ships, and where title or ownership of the goods transfers to the buyer. Orders shipped from outside Missouri to a Missouri address are subject to Missouri use tax, because Missouri taxes the privilege of selling tangible personal property in the state even when the seller itself is elsewhere. Orders that never touch Missouri and aren't delivered there owe neither Missouri sales nor use tax, whether they originate outside the state or are shipped out of the Applicant's own Missouri 3PL to an out-of-state address.

The key distinction in the ruling is what happens when the Applicant's Missouri 3PL fulfills an order for a Missouri customer. In that scenario, the Department held the transaction is subject to Missouri sales tax, not use tax, because title to the goods passes to the buyer inside Missouri under 12 CSR 10-113.200(1). In other words, having inventory and fulfillment happening on the ground in Missouri, combined with a Missouri delivery address, is enough to trigger sales tax (collected and remitted by the seller) rather than the use tax that would otherwise apply to an out-of-state seller's shipments into the state.

What this means for you

Online and e-commerce sellers using a 3PL

If you sell online and use a third-party logistics company to warehouse and ship your inventory, the state where that warehouse sits matters a great deal. Once you have a 3PL physically located in Missouri fulfilling orders to Missouri customers, the Department treats those sales as in-state retail sales -- subject to Missouri sales tax, with the seller responsible for collecting and remitting it -- rather than simply use tax on an out-of-state shipment.

Sellers registered for use tax but not sales tax

Being registered only for Missouri use tax may not cover you if part of your fulfillment happens from a Missouri location. This ruling shows the Department will look at where title transfers, not just where your company is headquartered, to decide whether sales tax registration and collection duties apply to specific transactions.

Multi-channel, multi-state fulfillment operations

If your fulfillment network spans multiple states, track each order's origin and destination separately. The same seller can owe use tax on some shipments, sales tax on others, and no Missouri tax at all on shipments that never touch Missouri or aren't delivered there -- the analysis is transaction-by-transaction.

Common questions

Q: Do I owe Missouri tax just because I ship products to customers in Missouri?
A: Yes, if you're shipping into Missouri from outside the state, that triggers Missouri use tax on those orders, even if you have no physical presence in Missouri other than the delivery itself.

Q: What if none of my inventory or customers touch Missouri?
A: No Missouri sales or use tax applies to orders that are fulfilled and shipped from outside Missouri to addresses outside Missouri, since the goods are never located in or delivered to the state.

Q: Why would the same online seller owe sales tax on some orders and use tax on others?
A: It depends on where title passes. When a Missouri-based 3PL fulfills an order for delivery to a Missouri address, title transfers inside Missouri, making it a taxable in-state retail sale (sales tax). When goods ship from outside Missouri to a Missouri address, it's treated as use tax instead.

Q: Can I rely on this ruling for my own online sales business?
A: Not directly. This letter ruling is binding on the Department only with respect to the Applicant who requested it, only for three years from its date, and only as long as the facts don't change and the underlying law isn't changed by the legislature or courts. No other taxpayer can rely on it, though it illustrates how the Department reasons about similar 3PL fulfillment fact patterns.

Q: Does it matter whether I sell through my own website versus a marketplace?
A: This ruling doesn't address marketplace facilitator sales -- the Applicant sold directly at retail through its own online orders. Marketplace-facilitated sales can involve different collection rules under separate Missouri provisions.

LR 8376

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 October 3, 2025.

The facts as presented in your letter ruling request are summarized as follows:

Applicant is a California company selling personal property at retail.  Applicant is registered in Missouri for use tax but not for sales tax.  It uses a third-party logistics company (3PL) located in Missouri to store and fulfill online retail orders.  It sells and ships orders both within and outside the state of Missouri.

ISSUE 1:

Are orders fulfilled and shipped from outside Missouri to addresses in Missouri subject to Missouri use tax?

RESPONSE 1:

Yes. Orders fulfilled and shipped from outside Missouri to addresses in Missouri are subject to Missouri use tax.

"A tax is hereby levied and imposed [...] upon all sellers for the privilege of engaging in the business of selling tangible personal property" in the state of Missouri.  Section 144.020.1, RSMo.

ISSUE 2:

Are orders fulfilled and shipped from outside Missouri to addresses outside Missouri subject to Missouri sales or use tax?

RESPONSE 2:

No.  Orders shipped from outside Missouri to addresses outside Missouri are not subject to either Missouri sales or use tax.

Section 144.020.1, RSMo, imposes a tax "upon all sellers for the privilege of engaging in the business of selling tangible personal property or rendering taxable service at retail in this state."  In this case the goods being sold are not located within Missouri or delivered to a Missouri location, therefore their sale is not subject to Missouri Sales tax.

ISSUE 3:

Are orders fulfilled and shipped from inside Missouri to addresses outside Missouri subject to Missouri sales or use tax?

RESPONSE 3:

No.  See Response 2 .  The personal property is delivered outside Missouri and therefore is not subject to Missouri sales or use tax.

ISSUE 4 :

Are retail orders fulfilled by Applicant's Missouri 3PL and shipped to Missouri addresses subject to Missouri sales or use tax?

RESPONSE 4:

Yes. Retail orders fulfilled by Applicant's Missouri 3PL and shipped to Missouri addresses are subject to Missouri sales tax.

"A tax is hereby levied and imposed [...] upon all sellers for the privilege of engaging in the business of selling tangible personal property", in the state of Missouri.  Section 144.020.1, RSMo.

12 CSR 10-113.200(1) states that:

In general, a sale of tangible personal property is subject to sales tax if title to or ownership of the property transfers in Missouri. The seller must collect and remit the sales tax.

In this case title passes inside Missouri, therefore sales tax must be paid.

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 Senior Counsel Kent L. Brown, General Counsel's Office, Post Office Box 475, Jefferson City, Missouri 65105-0475, phone (573) 751-0961.

Sincerely,
