Connecticut Sales Tax for Dropshipping Sellers — 2026 Guide

Updated 2026-04-27

If your Dropshipping business sells $100,000 or 200 transactions into Connecticut in a calendar year, you have economic nexus and must register, collect, and remit Connecticut sales tax.

Dropshipping sales tax in Connecticut

Dropshipping into Connecticut raises three distinct tax questions. First, you (the retailer) have to collect and remit Connecticut sales tax on your retail sales if you exceed $100,000 or 200 transactions. Second, your dropship supplier may charge YOU sales tax on the wholesale invoice if they have Connecticut nexus and you can't present a valid resale certificate. Third, the marketplace (if any) handles its own tax on facilitated transactions.

Connecticut applies 6.35% as the base state rate; no local add-ons apply.

Resale certificate rules

If you have a Connecticut sales tax permit, you can usually issue your dropshipper a CT 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.

Common dropshipping mistakes in Connecticut

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 Connecticut 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.

Connecticut nexus note

Economic nexus in Connecticut requires BOTH more than $100,000 in gross sales AND more than 200 separate transactions delivered into Connecticut in the prior year. Both thresholds must be met.
