Direct Pay Authority for Sales Tax

Direct pay authority allows businesses to buy all items exempt from tax. The businesses pay any tax due directly to the Tax Commission instead of to a vendor.

You might be approved for direct pay authority if all of these are true:

  • You qualify for sales tax exemptions.
  • You buy many items from different vendors.
  • You’ve demonstrated proper accounting and technical internal controls to comply with the Idaho Sales Tax Act.
  • The vendors you buy from have trouble tracking which items you buy are exempt and which aren’t (even though you supply them with an exemption certificate).

To apply

Your request must be in writing.

  • Send it to:
    • Mail address: Sales Tax Audit Bureau, Idaho State Tax Commission, PO Box 36, Boise ID 83722-0410.
    • Email: Submit a question. You should receive a response within 5 to 7 business days.
    • Write “Direct Pay Authority Request” at the top of your letter or email
  • Describe your reasons for needing direct pay authority and how it would benefit both you and the Tax Commission.
  • Include this information in your letter:
    • The name of your business
    • What goods or services you produce (what your business does)
    • What goods or services you typically need to buy exempt from sales tax
    • What percentage of your purchases in Idaho are exempt from sales tax
    • The sales price for these purchases in the past 12 months
    • Your anticipated sales price for these purchases in the next 12 months
    • Which exemption certificate you use (e.g., pdf Form ST-101 – Sales Tax Resale or Exemption Certificate) to buy exempt from your vendors
    • How you buy exempt from vendors without an exemption certificate (e.g., Optional short version of Form ST-101)

After you apply

Our Sales Tax Audit Bureau will review your request. If we need additional information, we’ll contact you. Please allow four to six weeks to hear from us.

Using your Direct Pay Authorization

Your direct pay authorization is valid for a defined period. Check the document for its expiration date.

  • Provide your vendors with a copy of your direct pay authority certificate to keep on file.
  • Contact us 45 to 60 days before your authorization’s expiration date to request a renewal.
  • Please contact us to cancel your authorization if it’s no longer is needed. Use a mail or email address in the “To apply” section above.
  • Let your vendors know if you cancel your authorization.

Temporary Seller’s Permits

Temporary seller’s permits allow you to make infrequent retail sales in Idaho. Sellers who typically get temporary permits are ones who, for example, sell at events such as farmers markets or craft fairs, have a seasonal stand for fireworks or Christmas trees, or sell from home once in a while.

Idaho residents who sell less than $5,000 per year and meet other requirements might qualify for the small seller exemption, which means they don’t need a temporary or regular seller’s permit. See the Small Seller Exemption page.

There are two kinds of temporary seller’s permits. 

For all Idaho events and other sales activities

This permit is good for selling at your own sales activities and any Idaho events. Retailers can request a temporary permit that can last up to the end of the calendar year.

For a specific Idaho event

This permit is good only for selling at one specific event. The permit’s valid for the length of the event, up to December 31 of the current calendar year.

Get this type of temporary permit only if you don’t already have the other temporary permit for your own sales, or a regular seller’s permit.

You can get up to three temporary seller’s permits per calendar year before you need a regular seller’s permit.

Who can’t get a temporary seller’s permit

You can’t get a temporary seller’s permit if you:

In these cases, you’ll need a regular seller’s permit. The only exception is if you only rent out lodging on a short-term rental marketplace like Airbnb or VRBO, and that marketplace collects and sends in all taxes due for all your Idaho sales. Make sure to verify that the marketplace is reporting your sales.

Aren’t sure if you need a temporary or regular seller’s permit? See Who needs a permit.

Applying

How you apply depends on which kind of temporary seller’s permit you want:

  • For your own sales activities and any events: Go to TEMPORARY seller’s permit and choose Seller WITHOUT event ID at the bottom of the page.
  • For a specific event: Contact the event promoter for instructions.

Filing and paying

See Filing and Paying.

Promoter-Sponsored Events

A promoter-sponsored event is either of these:

  • A regular series of events where retailers conduct business, such as farmers markets, swap meets, flea markets, gun shows, and fairs.
  • An event where two or more retailers offer, sell, or exchange products or services. The event promoter charges them a fee to appear, charges attendees a fee to enter, or both.

Retailers can be businesses, individuals, or even nonprofit organizations that sell, or make it known that they sell, a product or related service. A retailer is someone who does any of the following:

See the Sales and Use Taxes overview for more about what a sale is.

Special groups should see Sales Nonprofits Make or Sales Schools Make for more information about events these groups often hold and how sales tax applies.

Sellers at promoter-sponsored events

All participants at a promoter-sponsored event need to register for the event using the Event ID from the promoter. Retailers also need to do one of the following:

  • Use your regular seller’s permit, if you have one. During event registration, choose the option for I have a regular seller’s permit Report event sales with your other sales by your normal due date.
  • Use a temporary seller’s permit you got for your own activities (such as your own farm stand). During event registration, choose the option for I am not making taxable sales. Include your permit’s Reference # (from top of permit), its Valid from date, and its Valid through date in the Products I am selling field. Report event sales with your other sales within 15 days after your permit expires.
  • Get a temporary seller’s permit specific to the event when you register, only if you don’t already have another seller’s permit. Report your sales no later than 15 days after the event ends.

Promoters of events

As the event organizer, you’re considered a “promoter” and your event is considered a “promoter-sponsored event.” You must register your event with the Tax Commission.

Important: You could be charged a penalty of $25 per participant (to a maximum of $1,000) for not submitting the appropriate form for any event for which you’re the promoter.

  1. Beforehand, you must register your event online.
  2. You’ll enter information about yourself and your event.
  3. After you review what you entered and reach the confirmation page, we’ll send you an email with an Event ID. The email also includes instructions about how to share this Event ID with the participants (sellers) at your event.
  4.  You’ll receive a series of emails as your event date approaches. Use it to confirm that all your participants have completed their required actions.

Video: Promoters: How to register your event with the Tax Commission

If your participants aren’t online

As a promoter, you are responsible for ensuring all participants register for the event. If participants need assistance registering, contact us at taxsas@tax.idaho.gov.

Charging admissions

You must collect sales tax on the price of any admission you charge. See the Admissions section on this webpage: Taxable Sales – Recreation and Admissions.

IRP Basics Guide

This guide explains Idaho’s sales and use tax laws for IRP registrants. The guide describes motor vehicles, trailers, and glider kits that you can buy tax free under the IRP exemption. It also covers what you must pay tax on, and the requirements for keeping sales and use tax records and for filing returns.

Defining an IRP fleet

A fleet is one or more vehicles registered under the International Registration Plan (IRP).

  • The fleet must have at least one qualifying motor vehicle. The motor vehicle must have a maximum gross weight of at least 26,000 pounds.
  • The rest of the fleet can consist of a mixture of motor vehicles, trailers and glider-kit vehicles.

An individual or company can have more than one fleet.
