Who collects Connecticut sales tax on dropshipped orders?

You do, as the retailer. Your dropshipper invoices you at wholesale; you invoice the customer at retail. Collection duty follows the retail transaction — that's you.

Will my dropshipper charge me Connecticut sales tax on the wholesale?

Only if your dropshipper has Connecticut nexus AND you can't provide a valid CT resale certificate. Obtain resale certificates for every state where your dropshipper operates.

Does dropshipping trigger economic nexus in Connecticut?

Yes, your retail revenue into Connecticut still counts toward the $100,000 in gross sales OR 200 transactions threshold, independent of how fulfillment happens.

Can I use an out-of-state resale certificate for a dropshipper in Connecticut?

Usually yes — most states accept the Streamlined (SST form F0003) or MTC multijurisdiction resale certificate, so your CT dropshipper can take it instead of charging you tax on the wholesale invoice. But California, Florida, Hawaii, Illinois, Maryland, and Massachusetts reject an out-of-state certificate from the true retailer in a drop shipment and effectively require in-state registration (Florida also wants a transaction authorization number). Confirm Connecticut's current rule with its Department of Revenue. Verified 2026-06-27.

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

As of June 2026, a Connecticut drop shipment is a three-party sale: you collect Connecticut sales tax from your customer on the retail price once your sales into the state pass $100,000 or 200 transactions, while your supplier charges you tax on the wholesale invoice only when it has Connecticut nexus and you can’t give it a valid resale certificate.

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 certificates: which document each state accepts

If you hold a Connecticut sales tax permit, you can usually issue your dropshipper a CT resale certificate so it does not charge you sales tax on the wholesale invoice.
No Connecticut permit yet? Two multistate forms cover most states: the Streamlined Sales Tax Certificate of Exemption (SST form F0003), honored by all 24 SST member states, and the MTC Uniform Sales & Use Tax Resale Certificate, accepted by roughly 36 states.
A handful of states reject an out-of-state resale certificate from the true retailer in a drop shipment and effectively require in-state registration or extra paperwork — notably California, Florida, Hawaii, Illinois, Maryland, and Massachusetts. Florida also requires the supplier to obtain a transaction authorization number before honoring an MTC certificate. In those states a home-state certificate alone may not protect your supplier, so confirm the rule with that state’s Department of Revenue.

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.
