How-To Guides: Idaho SaaS Sales Tax

Step: 1 Threshold

You’ll need to collect sales tax in Idaho if you have nexus there. There are two ways 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 there. Economic nexus means passing a state’s economic threshold for total revenue or the number of transactions in that state.

 

Economic nexus is triggered when a remote seller has $100,000 USD or more in Idaho sales in the current or previous year. Registration becomes mandatory once this threshold is exceeded. Idaho does not use VAT/GST terminology; it operates a retail sales and use tax system.

Step: 2 Business Registration

Register with the Idaho State Tax Commission through the Idaho Business Registration System (IBRS). The process is completed online and creates a seller’s permit for collecting sales tax on taxable digital products and software services.

Step: 3 TIN/VAT Number

A Seller’s Permit / Sales Tax Account Number is issued by the Idaho State Tax Commission and functions as the tax identification number for sales and use tax purposes.

Step: 1 Standard Rate

Idaho state sales tax is 6% (certain resort towns and jurisdictions are allowed to charge an additional local sales tax rate). Prewritten software and remotely accessed software (SaaS) are treated as taxable tangible personal property under Idaho rules.

Step: 2 Sales Tax Formula

To calculate your tax amount, use the following formula:

Tax Amount = NetPrice × 6%

Step: 3 Reverse Charge (B2B)

Idaho does not operate a VAT-style reverse charge system. For B2B cross-border SaaS sales, if the seller is registered and has nexus, the seller must charge Idaho sales tax. If the seller is not registered but the service is taxable and used in Idaho, the Idaho business customer owes use tax directly to the state.

Step: 1 Selling B2C

“Canned” (prewritten) software that is downloaded or delivered on tangible media is taxable. Software as a Service (SaaS) is generally exempt because the customer does not receive a “copy” of the software (no download or physical media).

Step: 2 Selling B2B

Sales to Idaho businesses are taxable unless a valid exemption certificate applies. No reverse charge applies; instead, use tax rules require the buyer to self-assess if the seller does not collect. Exempt purchases must be supported by an Idaho resale or exemption certificate.

Step: 3 Invoice Requirements

The invoice must include: 

  • supplier legal name and address;
  • seller’s permit number;
  • invoice date;
  • sequential invoice number;
  • description of SaaS/digital product;
  • sales price;
  • separately stated Idaho sales tax;
  • buyer name and address;
  • exemption certificate reference (if applicable);
  • total amount due;
  • currency in USD.

Step: 1 Filing Interval

The filing interval is assigned by the Idaho State Tax Commission based on sales volume; typically, monthly, quarterly, or annually.

Step: 2 Filing Deadline

Returns are generally due on the 20th day of the month following the reporting period.

Step: 3 Submission

Filed electronically through Taxpayer Access Point (TAP), Idaho’s e-filing portal. Payments can be made via ACH debit, ACH credit, or approved electronic payment methods.

Step: 4 Record Keeping

Books and tax records must generally be retained for at least 4 years for audit purposes.
