ST-101, Idaho Resale or Exemption Certificate

pdf Form ST-101 – Sales Tax Resale or Exemption Certificate

Fill in the form:

  1. Write the name and address of both the seller and your business at the top.
  2. In section 2 “Producer Exemptions,” check the box for the producer exemption(s) you qualify for.
  3. List any products you produce on the line at the bottom of section 2.
  4. Under “Buyer,” at the bottom of the page, sign the form. Fill in the rest of the fields (name, title, EIN or driver’s license information, and date).
  5. The seller should keep the form and not charge you tax on exempt items in the future.

Optional short version of ST-101

  • Retailers can print or stamp a short version of the ST-101 on sales invoices, or
  • Buyers can print the short version on their purchase orders.
  • This shorter version must be completed for each sale. The wording must be:

I certify that the property I’ve purchased will be used by me directly and primarily in the process of producing tangible personal property by mining, manufacturing, processing, fabricating, or farming, or as a repair part for equipment used primarily as described above. This tax exemption qualifies if this statement is signed by the buyer and the name, address, and nature of the buyer’s business are shown on the invoice. Any person who signs this certification with the intention of evading payment of tax is guilty of a misdemeanor.

[Indicate spaces for NATURE OF BUSINESS and SIGNATURE OF BUYER]

Retailers should keep a copy of the sales invoice showing the stamped or printed exemption.

Multijurisdictional

You can use the Uniform Sales and Use Tax Certificate – Multijurisdiction when you buy from out-of-state businesses that are registered Idaho retailers instead of Form ST-101 if:

  • You’re a multi-state taxpayer, and
  • You’ll resell the goods you buy

Instructions:

  1. Write the name and address of both the seller and your business at the top.
  2. Check the box for “Retailer” if you sell to end users or “Wholesaler” if you sell to buyers who’ll resell the goods.
  3. Write your Idaho seller’s permit number in the ID section.
  4. Sign and fill in the bottom of the form.
  5. The seller should keep the form and not charge you tax in the future.

Note: Everything you buy using the Multijurisdiction exemption certificate is exempt because you can use it only for goods you’ll resell.

Remember: Even if you buy from a seller that has your exemption certificate, not everything is exempt.

  • Some items are always taxable.
  • Some items are taxable if they’re not used in qualifying activities.
