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

Dropshipping sales tax in Idaho

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

Dropshipping into Idaho raises three distinct tax questions. First, you (the retailer) have to collect and remit Idaho 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 Idaho nexus and you can't present a valid resale certificate. Third, the marketplace (if any) handles its own tax on facilitated transactions.

Idaho applies 6.00% as the base state rate; local add-ons average 0.03%.

Resale certificates: which document each state accepts

  • If you hold a Idaho sales tax permit, you can usually issue your dropshipper a ID resale certificate so it does not charge you sales tax on the wholesale invoice.
  • No Idaho 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 Idaho

  • 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 Idaho 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.

Idaho nexus note

Idaho sales/use tax nexus and economic nexus threshold: effective June 1, 2019, an out-of-state retailer without a physical presence in Idaho must collect Idaho sales tax once its combined Idaho sales exceed $100,000 in the current or previous calendar year. Idaho uses a sales-only threshold — no transaction-count test. The threshold counts all Idaho retail sales — taxable, exempt, wholesale, and sales facilitated through third-party marketplaces — and marketplace-facilitated sales still count toward a seller's own threshold even when the marketplace collects the tax. A marketplace facilitator without Idaho physical presence must register and collect once the combined total of its own sales plus the sales it facilitates for retailers exceeds $100,000. Idaho's state sales tax rate is 6%, with limited local resort-city and auditorium-district taxes. Idaho State Tax Commission source data last retrieved 2026-06-14.

Frequently asked questions

Who collects Idaho 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 Idaho sales tax on the wholesale?
Only if your dropshipper has Idaho nexus AND you can't provide a valid ID resale certificate. Obtain resale certificates for every state where your dropshipper operates.
Does dropshipping trigger economic nexus in Idaho?
Yes, your retail revenue into Idaho still counts toward the $100,000 threshold, independent of how fulfillment happens.
Can I use an out-of-state resale certificate for a dropshipper in Idaho?
Usually yes — most states accept the Streamlined (SST form F0003) or MTC multijurisdiction resale certificate, so your ID 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 Idaho's current rule with its Department of Revenue. Verified 2026-06-27.
