Physical nexus vs economic nexus: local inventory

Your webshop may be small enough to stay below a remote-seller sales threshold while its stock already sits in another state. A report that only flags sales totals will miss that operational change. Local fulfillment begins with physical goods at an actual address, so the tax review should begin there too. This article examines official California, New York and Illinois guidance checked on 14 October 2026 and turns those differences into a practical review before stock is transferred.

Why is a remote-sales threshold the wrong first test for local inventory? #

Economic nexus addresses a sales-based connection. Physical presence concerns the activities or property you have in a state. Start with the facts before applying the remote-seller label: who owns the goods, where they are stored and what the partner does. A third party’s ownership of the building does not necessarily remove your connection through inventory. Conversely, a state-specific exception can protect a qualifying arrangement. Both conclusions require more than knowing the parcel’s destination.

Build separate lists of customer destinations and stock locations. The first supports your sales-based tests; the second identifies places that need a physical-presence review. If your partner can move inventory between facilities, record those locations and the movement dates too. A provider’s headquarters address is not necessarily where your products are held. Ask for the actual storage locations rather than using the billing address from the fulfillment invoice as a substitute.

Keep the scope limited to the tax being reviewed. A sales-tax conclusion is not a finding about state income tax, business registration or employment obligations. If your accountant investigates those separately, give each review its own decision and sources. A note saying no nexus without naming the tax and factual arrangement is too broad to guide the person who will configure checkout or file a sales-tax return.

What does California say about stock at a third-party fulfillment center? #

CDTFA’s fulfillment-center guide says an out-of-state seller that stores inventory at a California fulfillment center is engaged in business in California and must register, file returns and address tax on California consumer sales. The guide separately distinguishes a fulfillment center that merely performs services from a center selling goods. Do not assume your packing provider reports your retail tax simply because it handles the goods and buys packaging.

The guide explains that an out-of-state retailer with a California location needs a seller’s permit, while one without a location needs a Certificate of Registration–Use Tax. It also gives specific registration guidance for inventory held with other owners’ goods at a fulfillment center. Read those instructions before answering the application’s location questions. A yes-or-no application response should reflect the agency’s definitions, rather than an informal assumption that owning products means owning the storage premises.

For a local packing arrangement, document whether you are retaining ownership until sale and whether the partner has authority to sell the goods. Storage and dispatch are different from a consignment retail arrangement. Describe what actually happens and obtain the state’s treatment for that arrangement when it does not fit the published examples. A contract title such as logistics partner is less useful than a clear statement about possession, ownership, selling authority and customer payments.

Why can qualifying New York fulfillment lead to a different answer? #

New York’s drop-shipment bulletin describes an exception for a seller not otherwise required to register that purchases fulfillment services from an unaffiliated New York provider. The listed activities include holding inventory on the provider’s premises and shipping orders. The bulletin also states that the provider must be registered for New York sales-tax purposes to collect tax or accept exemption certificates. Check the full arrangement and the provider’s status before relying on that exception.

Unaffiliated is a legal condition, not merely a description of somebody you have never met. You also need to establish that your business has no other registration trigger and that the work fits the covered fulfillment services. An exception for one qualifying service relationship does not erase a separate office, employee or sales-based connection. Record the basis for each condition, with a link to the guidance and the documents showing your actual agreement.

Do not promise that every person packing parcels from home qualifies as the statutory provider. A private agreement can describe similar work while leaving questions about affiliation, premises, registration or additional activities unresolved. If that is your intended setup, present its facts to the state or your adviser before moving inventory. The useful finding is conditional: a qualifying arrangement may avoid registration arising solely from those services, while an unverified arrangement remains a question to resolve.

Does the Illinois economic threshold still apply after you fulfill from local stock? #

Illinois Bulletin FY 2026-12 defines a remote retailer as an out-of-state retailer without Illinois physical presence. A retailer fulfilling any orders from its inventory in Illinois is not a remote retailer under that definition. Therefore, do not use the remote-retailer dollar threshold as the complete answer after introducing Illinois stock. Determine the applicable classification and rules for the arrangement that now exists.

Retain the date of the first local inventory placement and the first order fulfilled from it. Those are different events and may be relevant to different parts of the analysis. If a replenishment plan is postponed, update the operational record rather than leaving an assumed start date in the tax file. If the stock later leaves the state, keep the transfer and closing records so the next review can identify what actually ended and what connections remain.

How should you compare an AirPost dispatch price with a stock-location decision? #

On 14 October 2026, AirPost’s US-to-US page displayed USPS Ground Advantage from approximately $7.78 for a small package and $7.81 for a medium package. The published references include the platform fee and exclude the sender’s agreed payment. USD amounts are converted displays; the page says settlement is in euros. Obtain the actual address and parcel quote before budgeting a shipment.

The displayed size difference is $7.81 − $7.78 = $0.03. That narrow transport comparison does not answer whether your stock arrangement requires registration. A cheaper dispatch reference can coexist with additional tax administration at the chosen stock location. Keep the carrier comparison and the nexus review as separate decisions, then assess the combined setup. Neither advertised amount is a quote for preparing returns or registering your business.

AirPost’s published model lets a local sender hold stock and pack orders. Specify the state and actual address before treating that as your operating plan. US Shopify fulfillment choices describe the operational questions to settle. Your tax record then needs the particular stock relationship you selected; the description of a platform’s general service cannot establish the tax treatment of every seller and sender agreement.

What should a stock-location review contain before you send the goods? #

1. 1

   Identify the property and premises

   Name the inventory owner, actual storage address, permitted moves and planned start. Separate the partner’s billing address from the location of the goods.

2. 2

   Describe every service

   Record storage, packing, shipping, customer contact and any authority to sell. Note affiliation and the provider’s registration where relevant.

3. 3

   Check the state’s rule and exceptions

   Use the physical-presence rule before treating the business as a remote seller. Test every condition of a claimed fulfillment exception.

4. 4

   Save the conclusion and next action

   Keep the supporting documents and any written advice. Complete the required registration or resolve the outstanding facts before relying on the arrangement.

Revisit the record when the partner changes facilities, adds selling activities or accepts returns at another address. A return location can involve stock even if it does not normally dispatch new customer orders. Ask what happens to returned goods and who owns them while they are held. The review should follow your actual inventory movements, rather than ending when the original outbound packing agreement is signed.
