Idaho’s sales tax system might seem overwhelming with different local option tax rates and credits.

In this tax guide, we’ll cover the essentials, from calculating sales tax to understanding exemptions and use tax regulations. 

We’ll also introduce a trusted solution to simplify your sales tax filing process and ensure compliance in Idaho and across the United States.

Collecting Idaho Sales Tax from Customers

Let’s explore how you can collect Idaho sales tax from customers.

Do I Have to Collect Idaho Sales Tax from Customers?

If you’re a retailer located in Idaho or if you have sales tax nexus in Idaho, you must collect sales tax on taxable transactions in the state.

What Creates a Sales Tax Nexus in Idaho?

You have sales tax nexus in Idaho if you meet any of the following conditions:

• Economic nexus: Out-of-state businesses whose sales in Idaho exceed $100,000 in the current or previous calendar year.
• Physical nexus: Businesses that have an office, warehouse, or storage space temporarily or permanently in Idaho.

Do I Have to Collect Sales Tax from Idaho Customers if I Sell on Amazon, Walmart, eBay, or Etsy?

No. Idaho’s marketplace facilitator law requires platforms like Etsy and Amazon to collect sales tax on behalf of third-party sellers. However, smaller retailers who do not have a physical presence in Idaho only need to collect sales tax when the combined total of their own sales and their third-party sales in the state exceed $100,000.

FAQs on Paying and Filing Idaho Sales Tax

What Is Use Tax?

Use tax applies to goods you use or store in Idaho that haven’t been properly taxed. The use tax rate is the same as Idaho’s sales tax rate.

You probably owe use tax if you operate a business that: 

• Shops online or buys items from sellers that don’t collect Idaho sales tax
• Uses goods when performing a nontaxable service
• Brings equipment, supplies, or vehicles into Idaho for permanent use
• Brings business assets into Idaho for temporary use
• Does contracting work on real property in Idaho

I Didn’t Collect any Idaho Sales Tax During this Period. Do I still Need to File a Return?

Yes. 

You should still file a “zero” return with the state even if you didn’t collect any sales tax over the taxable period.  

What Is the Penalty for Filing and/or Paying Idaho Sales Tax Late?

If you don’t file a tax return on time, a penalty of 5% of the tax due is applied for each month the return is late, up to a maximum of 25%.

If you file a return but don’t pay the full amount of sales tax, you’ll incur a penalty of 0.5% of the tax owed for each month the payment is late, up to a maximum of 25%.

Can I Amend an Idaho Sales Tax Return? 

Yes, but amending a return cannot be done online. You must have a paper copy of your incorrect Form 850 and write ‘amended’ at the top of the form.  After you have made the necessary corrections on the form, you mail it back to the state. 

How Often Do I Need to File and Pay Sales Tax in Idaho?

When you register for your seller’s permit, you will be informed of your filing frequency. Most retailers file returns monthly. They file the form and remit the tax on the 20th of every month after their reporting period. 

Retailers with a tax liability of less than $750 per quarter file quarterly. Distributors or wholesalers with minimal taxable sales can apply to file semiannually (on July 20 and January 20) or annually on January 20.

Note: If the 20th falls on a weekend or holiday, the return and payment are due on the next workday.
