What is Idaho's e-commerce sales tax in 2026?

Idaho's 2026 e-commerce sales tax: out-of-state sellers collect once they cross $100,000 in Idaho-destination revenue. As a remote seller, charge the 6.00% state rate plus any applicable local rate at the buyer's ship-to address.

Do I collect sales tax on every Idaho order?

You collect Idaho sales tax once you cross the economic nexus threshold ($100,000). Below threshold, you don't need to collect unless you have physical nexus (office, employees, inventory in Idaho).

What rate do I charge for Idaho e-commerce sales?

For sales shipped into Idaho from out of state, charge the 6.00% state rate plus any applicable local rate at the buyer's ship-to address. Most e-commerce platforms (Shopify, WooCommerce) can apply destination rates automatically when you enable ID in tax settings. Sales that both begin and end inside Idaho can follow a different sourcing rule in a minority of states — check with the Idaho Department of Revenue if you are an in-state seller.

Do I need to collect sales tax on shipping in Idaho?

It depends on state-specific rules. Many states tax shipping when the product is taxable; some states exempt shipping if separately stated. Check Idaho's specific policy or use a tax service that encodes the rule.

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

E-commerce sales tax basics in Idaho

For a direct-to-consumer store (Shopify, WooCommerce, BigCommerce, or custom) shipping to Idaho buyers, the economic nexus trigger is $100,000 in ID-destination revenue (effective 2019-06-01). Crossing that bar obligates registration, collection, and periodic filing.

Once registered, charge 6.00% state tax plus the applicable local rate — averaging 0.03% across Idaho but varying by the buyer's shipping ZIP on most tangible personal property. Digital products, subscriptions, and professional services have different treatment — see the Idaho SaaS page if you sell software or digital goods.

Registration + collection checklist

Register with the Idaho Department of Revenue for a sales tax permit.
Configure your cart platform to collect tax at the destination rate. Enable ID in your tax settings.
As a remote seller, charge the combined state + local rate at the customer's delivery address — interstate sales are sourced to the destination, not to where you ship from.
File returns on the cadence your DOR assigns (monthly, quarterly, or annually).
Track your Idaho-sourced revenue monthly so you know when you're approaching or below threshold for the next period.

Common mistakes e-commerce sellers make in Idaho

Using origin-based rates (your HQ state's rate) instead of destination rates. A sale shipped from outside Idaho into Idaho is sourced to the buyer's delivery address, so charge the ID rate, not your home state's. Intrastate sales are a separate question: a minority of US states apply origin sourcing to sales that both begin and end in-state, so if your business is located in Idaho, confirm the intrastate rule with the Idaho Department of Revenue before configuring your cart.
Guessing at how marketplace sales count toward the Idaho threshold. States split on this — some let a seller exclude sales a registered marketplace facilitator already collected on, others require those sales to be included in the threshold test even though the marketplace remits the tax. Read Idaho’s own rule on the Idaho marketplace facilitator page before adding or removing them from your nexus-tracking spreadsheet.
Waiting until year-end to register. Registration and collection deadlines run from the threshold-crossing date, and the length of that grace period is set by each state — some require collection on the very next transaction, others allow until the first day of a later month. Check Idaho’s deadline with the DOR as soon as you cross $100,000; back-tax exposure accrues for every day you sell unregistered.
Forgetting to file zero returns once registered. Missing filings trigger penalties even when you owe no tax.

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.
