Change Use of Exempt Item – Logging

If you change the primary use of an item

If you buy an item exempt to use in a logging activity, it becomes taxable if you stop using it in a logging activity. You must then pay tax on the fair market value of the item.

Note: The opposite isn’t true. If you pay tax on an item because you use it in a non-logging activity, you can’t claim a tax credit if you begin to use it in a logging activity.

Buyer’s Responsibility for Logging Exemption

Buyer’s responsibility when making exempt purchases

You must keep records of all your purchases, and show whether you paid tax on them.

  • Records must show what you bought, when you bought it, how much you paid for the goods, and how much tax you paid.
  • Your accounting records must include the standard books and records maintained in a business.
  • Keep all your records for at least four years. (You may need to keep them for seven years if you don’t file sales tax returns).

Use tax

When you buy, use, or store taxable goods in Idaho, but didn’t pay sales tax when you bought them, you owe use tax.

You may owe use tax if:

  • You buy goods from an internet retailer that doesn’t collect tax
  • You buy a taxable item from a seller that didn’t charge sales tax because the seller has your exemption certificate on file
  • You buy an item in a state that doesn’t have sales tax, then bring the item to Idaho
  • You change how you use an exempt item (See If you change the primary use of an item.)
  • You take lumber from your resale inventory and use it in your business.

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, logging, 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.

  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.

Sales by or to Loggers

Selling the timber you harvest

Wholesalers

If you only sell goods to a customer who will resell them, you may be a wholesaler. Read more in our Wholesalers guide.

Retailers

If you sell to a final consumer, you might be a retailer. Read more in our Retailers guide.

Examples of sales you must collect tax on if you’re a retailer:

  • Selling logs to a contractor or employee
  • Selling logs to buyers who don’t resell them
  • Selling firewood for bonfires or campfires
  • Selling office equipment, used logging equipment, or promotional items to buyers who don’t resell them

Don’t charge tax if the goods you’re selling are:

  • Sold for resale, and the buyer gave you a completed pdf Form ST-101 – Sales Tax Resale or Exemption Certificate)or
  • Never taxed in Idaho
    Example: Firewood burned to provide heat to a building or for domestic home use isn’t taxable in Idaho. You might not need an Idaho seller’s permit if you only sell firewood for these purposes.

Vendors that sell to loggers

  • If you sell to loggers, don’t charge sales tax on exempt items if the buyer gives you a completed exemption certificate (e.g., ST-101).
  • If you have a completed certificate on file, don’t collect sales tax on exempt sales to the logger in the future.

Note: Not everything is exempt for loggers. You must charge tax on items that aren’t exempt from sales tax. Read more on making sales in our Retailers guide.
