Drop Shipments and Sales Tax Documentation

Drop-shipment transactions involve more than direct fulfillment. Multiple parties, separate sales, and state-specific documentation requirements can all affect sales-tax compliance.

Direct Shipping Does Not Simplify Sales Tax

The term “drop shipment” may be unfamiliar to manufacturers outside the United States.

It describes a transaction in which a seller accepts an order from a customer but instructs a separate supplier to ship the product directly to that customer.

The seller invoices the customer, the supplier invoices the seller, and the product never passes through the seller’s facility.

Although the logistics may appear simple, the transaction contains two separate sales and can create sales-tax obligations in the customer’s state.

The First Sale Is Generally Intended for Resale

The first sale—from the supplier to the seller—is generally intended to be a wholesale sale for resale.

To avoid charging tax, the supplier usually needs a valid resale certificate from the seller.

The difficulty is that the seller may be registered only in its home state, while the supplier is located in one state and the product is delivered into another.

Drop-Shipment Documentation Varies by State

Some states permit a supplier to accept an out-of-state registration number or a multistate certificate for a qualifying drop shipment.

Others impose state-specific forms, registration-number requirements, or special drop-shipment rules.

A certificate that works for an ordinary wholesale purchase may therefore be rejected when the delivery destination changes.

The Second Sale Must Be Analyzed Separately

The second sale—from the seller to the customer—must be analyzed separately.

The seller may need to register, collect, and remit tax in the destination state because of economic nexus, physical presence, inventory, personnel, or other activity.

If the customer is purchasing for resale, the seller must collect the customer’s valid resale certificate.

If the customer claims a hospital, governmental, prescription-device, or other exemption, the seller must obtain the documentation required by that state.

The customer’s exempt status does not automatically resolve the supplier-to-seller transaction.

Problems Often Surface After the Order Is Accepted

A supplier may refuse to ship without an acceptable certificate, charge tax that the seller did not include in its customer price, or treat itself as responsible for tax because the seller is not registered in the destination state.

The seller may then face unexpected tax cost, delayed delivery, margin erosion, refund claims, or audit exposure.

Blanket Certificates Require Ongoing Controls

Legal names, addresses, registration numbers, covered products, effective dates, expiration dates, and changes in shipping destinations must remain accurate.

These controls should be built into customer onboarding, order review, tax coding, certificate storage, and fulfillment approval so that documentation issues are resolved before an order is released.

Establish a Controlled Process Before Orders Are Released

Under the MDD Options hybrid model, MDD Options can act as the U.S. seller and operating distributor, manage applicable sales-tax registrations, collect and maintain customer certificates, invoice the customer, coordinate fulfillment, and preserve the records needed to support wholesale or exempt treatment.

This removes the multistate documentation burden from the manufacturer and establishes a controlled process before orders are released.

Where a manufacturer retains its own selling structure, MDD Options can also help assess drop-shipment flows, certificate requirements, and registration gaps with qualified tax advisers.
