Indiana Sales Tax for Dropshipping Sellers — 2026 Guide

Dropshipping into Indiana raises three distinct tax questions. First, you (the retailer) have to collect and remit Indiana sales tax on your retail sales if you exceed $100,000. Second, your dropship supplier may charge YOU sales tax on the wholesale invoice if they have Indiana nexus and you can't present a valid resale certificate. Third, the marketplace (if any) handles its own tax on facilitated transactions.

Indiana applies 7.00% as the base state rate; no local add-ons apply.

• If you have a Indiana sales tax permit, you can usually issue your dropshipper a IN resale certificate to avoid being charged sales tax on the wholesale invoice.
• Some states (notably California, Florida, Massachusetts, Tennessee, and a few others) require the buyer to hold an IN-STATE registration before issuing a resale certificate — a home-state certificate isn't enough.
• Streamlined Sales Tax (SST) states accept the uniform Multistate Certificate; others have their own forms.

• Treating your dropshipper's nexus as if it obligates them to collect from the end customer — no, they invoice you at wholesale; you invoice the customer at retail. Only the retail transaction is subject to collection duty.
• Forgetting that your retail revenue into Indiana still counts toward the economic nexus threshold, independent of the dropshipping arrangement.
• Not keeping resale certificates on file — your supplier will charge you tax (and you'll have already collected from the customer), eroding margin.
