Nexus · Idaho

When you owe sales tax in Idaho.

Either kind of nexus on its own creates the obligation to register, collect, and remit. Idaho uses a sales-only test for economic nexus — there is no transaction-count threshold.

Economic nexus
Threshold
$100,000 in sales delivered into Idaho
Measurement type
Sales only — transaction count does not matter
Measurement period
Current or preceding calendar year
Included
Gross sales, including marketplace-facilitated sales — all sales into Idaho count toward the threshold regardless of whether a marketplace collected the tax
Marketplaces
Marketplace-facilitated sales count toward your threshold — sales through Amazon, Etsy, or other registered marketplace facilitators are included in your gross sales when measuring whether you meet the $100,000 threshold
Physical nexus
Office or place of businessEmployees / remote workersWarehouse or inventoryThird-party fulfillment (3PL / FBA)Agents or contractors

Any physical presence in Idaho — including inventory stored at a warehouse or fulfillment center — creates nexus from the first sale, regardless of sales volume. Remote employees working from Idaho also establish physical nexus immediately.

Taxability · Idaho

Is your product taxable here?

Idaho taxes tangible personal property and digital goods, but exempts SaaS and most services — an important distinction for software and digital businesses selling into the state.

Product categoryStatusWhat to know
Tangible personal propertyTaxablePhysical goods delivered into Idaho are taxable at the flat 6% statewide rate.
Digital goodsTaxableElectronically delivered digital products — including downloads, e-books, and digital media — are subject to Idaho sales tax at 6%.
SaaS & cloud softwareNot taxableRemotely-accessed software is not subject to Idaho sales tax for either B2B or B2C sales — no transfer of tangible property means no taxable transaction.
Professional servicesNot taxableConsulting, legal, design, and similar professional services are exempt from Idaho sales tax.
General servicesNot taxableMost general services are not taxable in Idaho. Only services that are part of producing or installing a taxable good may take on the tax treatment of that good.
Shipping & deliveryPartialSeparately stated shipping charges on taxable goods are generally exempt when shipped by common carrier; charges bundled into the selling price are taxable. Itemize freight on invoices.
Filings · Idaho

Filing schedules and due dates.

The Idaho State Tax Commission assigns your filing frequency at registration based on expected tax liability and adjusts it as your business grows. Returns are due even for periods with zero taxable sales.

A Commenda expert will review your Idaho exposure, register you with the Idaho State Tax Commission, and take over the filing calendar — usually within a week.

The state authority

Idaho State Tax Commission — the state's tax office.

The Idaho State Tax Commission administers sales and use tax through its online Tax Access Point (TAP) portal. One account covers registration, filing, and payment — no separate local portals are required.

tax.idaho.gov

Registration requires a Tax Portal username and password. You will also need your business entity details and an EIN or responsible-party identification. Your State Tax ID (format XXXXXXXXX-XX) is assigned after registration.

What you can do there
  • Register for a sales tax permit

    Register online through the Idaho Tax Commission's TAP portal. There is no fee to obtain an Idaho seller's permit.

  • File returns and pay

    All Form 850 returns and payments are submitted through your TAP account on the schedule assigned at registration.

  • Look up the rate for any address

    Idaho's rate is a uniform 6% statewide. The Tax Commission's website confirms the current rate and any resort-area exceptions.

  • Verify a resale or exemption certificate

    Confirm that a customer's Idaho seller's permit is active through the Tax Commission's online verification tools before accepting an exemption claim.

Exposure & exemptions · Idaho

If you're behind, or your buyers are exempt.

Back-period exposure & voluntary disclosure

Idaho participates in the Multistate Tax Commission's voluntary disclosure program, allowing out-of-state sellers to come forward before the Tax Commission contacts them.

Lookback
Typically limited under a VDA — versus unlimited exposure if the state contacts you first
Penalties
Generally waived under a voluntary disclosure agreement
Interest
Still due on unpaid tax; relief is limited
Unfiled returns
Statute of limitations does not run until a return has been filed

Exemption certificates accepted

Collect a valid exemption certificate at the time of sale and retain it on file — the burden of proving the exemption falls on the seller.

Resale
Idaho ST-101 Sales Tax Resale or Exemption Certificate
Multi-state
MTC Uniform Sales & Use Tax Certificate accepted; Idaho is not a member of the Streamlined Sales Tax (SST) governing board
Government / nonprofit
Sales to qualifying government entities are exempt; nonprofit exemptions are limited — verify eligibility with the Tax Commission
Manufacturing / agriculture
Qualifying manufacturing equipment and certain agricultural inputs may be exempt under Idaho Code — use ST-101 with the applicable exemption code

You have economic nexus in Idaho once you exceed $100,000 in sales delivered into the state during the current or preceding calendar year. Idaho uses a sales-only test — there is no transaction-count threshold.

Yes. Electronically delivered digital products — including downloads, e-books, and digital media — are subject to Idaho sales tax at the full 6% rate. This is one of the key differences between Idaho and states like California or Nevada, where digital goods are exempt.

No. Remotely-accessed software — both B2B and B2C — is not subject to Idaho sales tax. Because SaaS involves no transfer of tangible property or a downloaded product, it falls outside the taxable base.

Yes. Idaho measures gross sales including marketplace-facilitated sales. Even when a marketplace facilitator like Amazon or Etsy collects the tax on your behalf, those sales are included in your gross sales total when measuring whether you exceed the $100,000 threshold.

Idaho's statewide rate is 6%. Unlike many states, Idaho does not impose a general local sales tax, so the 6% rate applies uniformly across Boise, Meridian, Nampa, Idaho Falls, Pocatello, and all other locations. Some resort cities may levy a small additional tax, but those are narrow exceptions.

Yes. Storing inventory at any warehouse, fulfillment center, or third-party logistics provider in Idaho creates physical nexus immediately — from the first sale, regardless of your total sales volume.

If the Idaho State Tax Commission identifies you before you register, you lose the protection of a voluntary disclosure agreement. Back taxes, interest, and penalties can extend further into the past with no lookback limit if you have never filed a return.

Yes. Commenda monitors your exposure, registers you with the Idaho State Tax Commission, calculates the correct rate on every transaction, and files each return on schedule. Book a call to see it working on your own data.
