Idaho Sales Tax FAQ


Idaho Sales Tax FAQ

By now, you may have already contacted the Idaho State Tax Commission and applied for an Idaho sales tax permit.

Let’s go over some common questions that our clients ask. We believe these questions will help you appreciate the nuances of taxable goods so you can be confident in fulfilling your tax obligations.



What goods and services are considered taxable in Idaho?

The following items are all taxable in the state of Idaho:

  • Sales of tangible goods at retail.
  • Repairs or alterations of tangible personal property.
  • Property rentals, leases, or licenses [e.g. commercial, mini-warehouse]
  • Selling service warranty contracts.
  • Rental/lease of goods w/o an operator (e.g.: vehicles, equipment, or other property).
  • Charges for admission to any place of amusement, sport, or recreation.
  • Manufacturing or producing goods for retail sales.
  • Operating vending machines or amusement rides


The bottom line is …

Let’s now review some of our clients’ other frequently asked questions:

  • Is Idaho an Origin or Destination sales tax State?
  • What creates a sales tax nexus in Idaho?
  • What is the economic threshold in Idaho?
  • Does Amazon have fulfillment centers in Idaho?
  • Does Idaho have a Click-Thru Nexus?

To better understand your tax obligations, new businesses need to consider how they are doing business and the type of relationships they have with buyers and any third parties to their transactions.

Let’s discuss some questions that will help you understand the nature of your own business and the subsequent tax implications.



Is Idaho an origin or destination sales tax state?

Idaho is a Destination-Based sales tax state, with a potential additional discretionary sales surtax based off the locality the buyer lives in. This means you’ll need to have a Point-of-Sales system configured to track tax based off the buyer’s location.



Protip: Charge Idaho Sales Tax based on the location of the buyer.



What creates a tax nexus with the state of Idaho?

Having nexus, also known as "sufficient business presence,” with Idaho means your business has established a taxing connection with a state. When this happens, you are required to collect and remit sales tax in Idaho because you created a sales tax Nexus.

Even if your business maintains its main headquarters in another state, you may still have to charge and pay sales tax to the Idaho State Tax Commission even if you never step foot in Idaho.

So, how do you create a sales tax Nexus in Idaho?


A business establishes a nexus in Idaho by:

  • having a business location in Idaho;
  • having property stored in Idaho;
  • employing any person in Idaho;
  • contracting with a salesperson or other agent in Idaho;
  • leasing equipment used in Idaho;
  • performing services in Idaho;
  • licensing the use of intangible property in Idaho, or transporting property in Idaho using the taxpayer’s vehicles.



Does Amazon have fulfillment centers in Idaho?

No, there are no Amazon fulfillment centers in Idaho at this time.



Does Idaho have economic nexus?

Sure does! In a response to the Supreme Court’s Wayfair ruling, starting June 1st, 2019, Idaho will require out-of-state companies which otherwise lack nexus to register and pay sales tax should their sales exceed $100,000 in a year.


Affiliate marketing sales tax




Does Idaho have click-through nexus?

Yes, Idaho now has click-through nexus laws. From their website:

“You must have a valid Idaho seller's permit, collect sales tax, file sales tax returns, and forward the tax to the state if you meet all these criteria:

  • You have no physical presence in Idaho.
  • You entered into an agreement with one or more Idaho retailers.
  • The agreement is for the Idaho retailer to refer customers to your business.
  • You made retail sales to Idaho customers exceeding $10,000 during the preceding 12 months.
  • You meet the criteria described in House Bill 578: Out-of-State Retailers.”

Companies will need to bear this in mind if they employ any affiliate marketers or provide affiliate marketing services to retailers in Idaho.



Is Idaho a streamlined sales tax state?

Nope! When this article was written, Idaho wasn’t yet participating in the multistate tax simplification program.

Here’s hoping that they might join up with this organization in the future 🤞!



Manage your tax needs more effectively by keeping this guide handy.

You and your business can be better-equipped to avoid situations like paying fines, paying back taxes that you did know you had to pay in the first place, or facing an audit by the tax authorities in Idaho.



Collecting Sales Tax in Idaho

Collecting Sales Tax in Idaho

If you are a business that has established a nexus with Idaho, you are required to collect sales tax. Knowing this is just half the battle! Now, we are going to help you with the next half of the battle: how to navigate the process of collecting taxes.

Let’s review some common questions our clients have asked regarding their Idaho Sales Tax obligations.

  • How do I collect Idaho Sales Tax?
  • Who is eligible for Idaho Sales Tax exemptions?
  • What should I do if my customer is exempt from sales tax in Idaho?
  • What happens if I lose an Idaho nontaxable transaction certificate?

After reading this, you will be better equipped to determine when --and when not-- to collect sales tax in Idaho.



How do I collect Idaho Sales Tax?

Remember when we noted that Idaho is a destination-based sales tax state? This means that the ultimate rate to charge will vary in accordance with the local sales surtax for the locality in which the buyer is located.

Any Point-of-Sales software worth its price should have this capability baked in. If the one you’re using does not, we can always recommend a superior solution. That’s the kind of nerding out that we love to do for our clients! 🤓🤩



What are the current Idaho Sales Tax rates?

As of June 2019, the tax rate in Idaho is 6%. However, because sales tax rates change frequently --and may vary by what is being sold-- we are going to refer you to check out the Idaho State Tax Commission site here for the most up to date information.

It can’t hurt to double check the sales tax rates to be sure.



What is exempt from Idaho Sales Tax?

Sales Tax exemptions in Idaho


Here are some examples of exemptions:

  • Purchases for resale
  • Livestock sold at market
  • Prescription drugs

For more information, see a complete list here for more details.



Who are eligible for Idaho Sales Tax exemptions?

At this point, you should know what products are exempt from sales tax in Idaho. You will also want to know who may be exempt.

Under Idaho law, the type of buyer or the way the goods will be used can qualify can buyer for a sales tax exemption. A good example of this is a merchant purchasing goods for resale, aka a wholesaler.

Other common examples of an exempt buyer may include:

  • Government agencies
  • Non-profit organizations
  • Religious groups
  • Out-of-state buyers (should their business not have nexus in their home state).

Idaho has a handy dandy list of exempt purchasers here.



What should I do if my customer is exempt from sales tax in Idaho?

As a business owner, you will most likely have a buyer who qualifies for a sales tax exemption.

It is up to you to collect a completed Idaho sales tax exemption certificate (Form ST-101, PDF) at the point of sale and to keep it on file.

An inability to produce the tax exemption certificate later may result in the outstanding tax being passed on to the seller, potentially with fees and penalties. No bueno, and very avoidable!



PROTIP: Tax exempt certificates must be produced upon request in the event of an audit to justify tax-exempt sales.



What happens if I lose an Idaho Sales Tax exemption certificate?

Youch! Obviously this issue is best to be avoided. Finding out you’ll be audited and learning you cannot produce an exemption certificate for a buyer would mean you could be held liable to pay all taxes on behalf of the buyer. This is a bad scene and can be avoided by being careful with your paperwork… which happens to be one of our specialties! :)



Does Idaho have a sales tax holiday?

Negative! 365 days of steady taxin’ :(




We have now covered who you need to collect sales taxes from, how to determine whether goods for sale are deemed taxable, what goods and services fall under tax exemptions, who is eligible for tax exemption certificates, and, finally, the process of collecting sales tax in Idaho state.

Now that we’re this far down the rabbit hole there’s only one thing we need to learn about next… how to pay the piper!

What happens if I don’t collect sales tax?

If you were required to collect sales taxes (nexus in Idaho and selling taxable goods or services to taxable residents) and failed to do so for whatever reason, you will be held responsible for the tax due.
