How to calculate Sales Tax in Idaho?

Businesses and Sellers who have Nexus are required to pay Sales tax to Idaho (state and local) on the sale, rental, or lease of tangible personal property as well as the sale of some services. They are required to collect, manage, and transfers it to the Idaho State Tax Commission while staying in compliance with state laws and avoid penalties and interest.

The sales tax determined on four factors:

  1. Nexus: It is a connection of business with a state. The business is only liable to pay taxes to the states with Nexus.
  2. Location and Products or Services: The sales tax rate varies from product to product and location to location, so you must check the sales tax rate applicable to your product according to the product category, county, and city in Idaho.
  3. Exemptions: Almost all goods are eligible for sales tax regulation. However, products, including Groceries (partially-exempted), prescription medicine, medical devices, and few more, are exempted under Idaho Law. So you should check with Idaho state government as to which goods and services sold in Idaho are subject to sales tax.

To calculate Sales Tax in Idaho, follow the steps below:

Step 1 – Determine your Nexus:

You, as a Business owner, are only required to collect sales tax if you are eligible for collecting sales tax and have Sales Tax Nexus in the Idaho State. And to determine your Nexus in Idaho, you must have any of the following:

  • A physical location like office, warehouse, plant, retail store, or other places of business.
  • An employee working for you in this state.
  • A stock of goods in the state.
  • Selling, delivering, installing, or taking orders in Idaho through a salesperson, agent, or representative.

Step 2 – Determine the Sales Tax Rate:

Once you have determined that your Nexus is with Idaho, next is to deduce the Sales Tax rate (State + Local Sales Tax) applicable on your product, for which you can refer the tables below:

  • Prescription Drugs are exempted from Idaho Sales Tax. Unfortunately, the food isn't exempted. However, low-income taxpayers are allowed to claim the tax credit on food purchases.

Step 4 – Calculate Sales Tax:

After determining the sales tax rate according to the location and type of purchases, it is easy to calculate the sales tax amount charged on the product and gross price (amount after tax) of a product.

Example # 1:

For instance, you are selling a washing machine on your store in Sandpoint, Idaho, having a net price tag of $250. The amount that a buyer has to pay (including sales tax) on a check out would be:

Manual Method:

Net Price (amount before Tax) of a Washing Machine: $250

Total Sales Tax rate: 1.00% (Sandpoint) + 0.00% (Bonner County) + 6.00% (Idaho State) = 7.00%

Total Sales Tax amount = $250 x 7.00% = $17.5

Gross Price (Amount after Tax) = 250 + 17.5 = $267.5

It means the buyer has to pay for a washing machine on a cash counter, which would be $267.5.

Using our Sales Tax Calculator:

All of the steps mentioned above can be skipped to get an instant result using our Sales Tax Calculator. All you need is:

  1. Input the $250 Net Price of a washing machine as Amount Before Tax
  2. Input or select 00% of the combined Sales Tax rate on the Tax Rate menu.

Our calculator will automatically calculate the result, and represents it in 3 different forms, as shown in the image below:


Reverse Sales Tax Calculation

In the example above, we have explained to you to calculate the Sales Tax amount payable in a product, and the Gross Price of the Product.

But there are also instances when you are required to deduce how much sales tax buyer has actually paid on a product or you may want to check the accuracy of the sales tax indicated on your item's receipt.

This is where the Reverse Sales Tax Calculation Kicks in. And luckily, our Idaho Sales Tax Calculator can perform this calculation like a Pro.


Your buyer has paid $350 for a Clothes Dryer Machine at your store in Aberdeen, Idaho. Now the buyer is inquiring how much the Clothes Dryer Machine actually cost before the sales tax was added. So you need to follow the steps below to determine the amount before tax (net price) of a Clothes Dryer Machine:

Gross Price (Amount after Tax) of Clothes Dryer Machine: $350

Total Sales Tax rate: 0.00% (Aberdeen) + 0.00% (Bingham County) + 6.00% (Idaho State) = 6.00%

Manual Method:

Gross Price with sales tax = [Net Price × (tax rate in decimal form + 1)]

350 = [Net Price x ((6/100) + 1)]

350 = Net Price x 1.06

$330.2 = Net Price

So the original Price (net price) of the Clothes Dryer Machine was $330.2.

Using our Sales Tax Calculator:

You can also use our Sales Tax Calculator for Reverse Sales Tax calculation to skip the aforementioned manual method. All you need is:

  1. Input the $350 Gross Price of Clothes Dryer Machine as Amount after Tax
  2. Input or select 6.00% of combined Sales Tax Rate on the Tax Rate

Our calculator will automatically calculate the result and represents it in 3 different forms.
