Idaho State Tax Commission

Do you need to collect and remit sales tax in Idaho? 

Most businesses that sell tangible personal property or taxable services in Idaho are required to collect and remit sales tax. The Idaho State Tax Commission defines tangible personal property as, “anything you can feel, see, touch, weigh, or measure.” However, this doesn’t include real property. Businesses with a physical presence in Idaho as well as those outside the state who make a certain number of gross sales into the state are both liable for sales and use tax. However, there are certain exemptions available for specific types of sales, such as sales to non-profit organizations or certain medical equipment ,including those related to sales tax in Idaho. If you need a more detailed list of businesses, organizations and items that are exempt from sales tax, you can find it here


Do you have sales tax nexus in Idaho? 

If you’re wondering whether you have sales tax nexus in Idaho, which is essential for Idaho sales tax filing, it’s important to first define what sales tax nexus is. Nexus is the connection between a business and a state that triggers the obligation to collect and remit sales tax. In Idaho, a business has physical nexus if it has physical presence in the state, such as a storefront or warehouse. This applies to both in-state and out-of-state businesses that make sales into Idaho, who are likewise responsible for sales tax in Idaho. But what about remote retailers or those who sell exclusively online? These types of businesses will still have nexus in Idaho if they make a certain amount of gross income from Idaho customers. This type of nexus is referred to as economic

Physical sales tax nexus in Idaho 

Retailers with physical nexus are described as doing business in Idaho if: 

  1. They own property in Idaho 
  2. They have an office, warehouse, sales room, or employees in Idaho 
  3. They have sales representative or agents in Idaho 
  4. They keep goods in Idaho that will be sold 

Note: Something that Idaho does a little different from many states, including how they handle sales tax in Idaho, is imposing a contractor tax on contractors. This is because Idaho views contractors as the consumers (or end-users) of all the goods they use. Contractors must therefore pay sales tax on all purchases, including equipment, tools, and supplies they use on their projects, which is a relevant part of Idaho sales tax filing. You can find more details on Idaho contractor tax here

Economic sales tax nexus in Idaho 

For a business to have economic nexus in Idaho, they must meet these two requirements: 

  1. Be a retailer located outside the state with no employees, merchandise, or otherwise residing in the state. 
  2. Make more than $100,000 in gross sales of tangible personal property to Idaho residents. 


Are marketplace facilitators required to collect and remit sales tax in Idaho? 

Yes. As of July 1, 2019, marketplace facilitators are required to collect and remit sales tax on behalf of their third-party sellers. Under Idaho law, a marketplace facilitator is responsible for collecting and remitting sales tax on all taxable sales made through its platform, unless the third-party seller can demonstrate that it is already collecting and remitting sales tax on those sales.  

What platforms are marketplace facilitators? 

  • Amazon    
  • Ebay    
  • Etsy    
  • Walmart (online)    

Not sure what defines a marketplace facilitator? In short, marketplace facilitators are companies that provide a platform or service for third-party sellers (you) to sell their products or services to customers. The facilitator collects payment from the customer, processes the transaction, and may also manage shipping and returns.
