How Does Drop Shipping Affect Multistaste Taxes?

Sam Brotman Sam Brotman, J.D.|Last updated May 2026

Quick Answer

Drop shipping creates four potential taxpayer problems: (1) unclear which party collects sales tax — retailer or drop shipper; (2) resale certificate acceptance varies by state; (3) nexus may be created in customer's state for either party; and (4) marketplace facilitator laws may shift obligations. The short version is that drop shipping is one of the most complex sales tax scenarios. In our experience, the retailer typically collects from the final customer, but state-specific resale certificate rules determine drop shipper liability.1

1. Who Collects Sales Tax

Retailer collects from final customer typically.

If this is you: Drop shipping arrangement. Retailer collects from customer based on customer's state. Drop shipper's role separate. Resale certificate acceptance critical.

Collector Strategy

  1. Identify retailer vs. shipper roles.
  2. Determine customer delivery state.
  3. Apply that state's rules.
  4. Maintain resale certificates.
  5. Track transactions carefully.

2. Resale Certificate Acceptance

State-specific acceptance of out-of-state resale certificates.

If this is you: Drop shipper needs resale certificate from retailer. Some states require in-state certificate. Some accept home-state. Check state-specific rules.

3. Nexus in Customer State

Retailer nexus measured by its own activities in customer state.

If this is you: Retailer with customers in many states. Each state's nexus rules apply. Economic or physical nexus creates collection obligation.

4. Marketplace Facilitator Impact

Marketplace facilitators may collect and remit.

If this is you: Selling through marketplace with drop ship fulfillment. Marketplace collects sales tax. Your direct sales (not through marketplace) separate analysis.

The ROI Question

Certificate failures create drop shipper liability. Proper documentation prevents audit exposure.

Dealing with Multistate Tax Exposure?

Multistate obligations don’t announce themselves — most businesses accumulate sales tax, income tax, or payroll tax exposure in other states without realizing it until they’re contacted or audited. If you’re selling across state lines, have remote employees, or aren’t sure where your business has nexus, a brief review can identify where you have exposure and what to do about it.
