Do you need to collect sales tax in Idaho?

You’ll need to collect sales tax in Idaho if you have nexus there. There are two ways that sellers can be tied to a state when it comes to nexus: physical or economic. Physical nexus means having enough tangible presence or activity in a state to merit paying sales tax in that state. Economic nexus means passing a states’ economic threshold for total revenue or the number of transactions in that state.

Do you have physical nexus in Idaho?

Idaho considers a seller to have physical nexus if you have any of the following in the state:

  • an office, warehouse, sales or sample room, or storage place
  • a stock of goods
  • renting or leasing property (other than real property) to a customer who uses the property in Idaho
  • business servicing tangible personal property in Idaho
  • a salesman, agent, or representative who comes to Idaho to sell, deliver, install, or take orders. (It doesn’t matter whether the salesman, agent, or representative is your employee, or whether he lives in Idaho or another state.)

Do you have economic nexus in Idaho?

Effective June 1, 2019, Idaho considers businesses who make over $100,000 in sales to customers in Idaho to have economic nexus. This means the state considers these vendors obligated to collect sales tax from buyers in the state. You can read Idaho’s economic nexus guidance for businesses here, and you can read more about economic nexus in every state here.

Is what you’re selling taxable?

Services in Idaho are generally not taxable. However – if the service you provide includes creating or manufacturing a product, you may have to deal with the sales tax on products.

Tangible products are taxable in Idaho, with a few exceptions such as prescription drugs.

Collecting Sales Tax

Idaho is a destination-based sales tax state for in-state sellers. So if you live and run your business in Idaho you would charge sales tax at the rate of your buyer’s ship-to location.

Fortunately, the sales tax rate in Idaho is generally just the state rate of 6%, even though certain resort towns and jurisdictions are allowed to add on an additional local sales tax rate.

If you are not based in Idaho but have sales tax nexus in Idaho, then you are only required to charge the 6% “use tax” rate to your Idaho buyers. (“Use tax” is very similar to sales tax but charged by sellers based out-of-state.)

You can look up your local Idaho sales tax rates by using the TaxJar’s Sales Tax Calculator.

Should you collect sales tax on shipping charges in Idaho?

As long as you separately state the shipping charges on your bill to your customer, you do not have to charge sales tax on shipping.

But if you include shipping in the price of the product you sell the customer, then shipping is considered part of the taxable transaction and Idaho declares that you must collect sales tax on shipping.

When are Returns Due?

When you file and pay Idaho sales tax depends on two things: your assigned filing frequency and your state’s due dates.

How often will you file sales tax returns in Idaho?

States assign you a filing frequency when you register for your sales tax permit. In most states, how often you file sales tax is based on the amount of sales tax you collect from buyers in the state.

In Idaho, you will be required to file and remit sales tax either monthly, quarterly or annually.

Idaho sales tax returns are always due the 20th of the month following the reporting period. If the filing due date falls on a weekend or holiday, sales tax is generally due the next business day.

Filing Sales Tax

When it comes time to file sales tax in Idaho you must do three things:
