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

Sales by or to Miners

Selling the goods you produce by mining or processing ore for sale

Taxable Items – Lumber Manufacturing

The production exemption guide lists items that are always taxable. Taxable items that are specific to lumber manufacturers include:

  • Equipment and supplies used for filing blades, such as grinders and grinding wheels
  • Equipment used for loading lumber products onto railway cars and trucks
  • Generators used to produce electricity to power non-production equipment (co-generation equipment)
  • Equipment and materials used for shipping
    Examples:
    • Strapping or binders used to secure lumber on railroad cars or trucks
    • Airbags and lumber used as dunnage
  • Shop equipment and supplies used to make repairs
    Examples:
    • Hand tools
    • Power tools and compressors, including their accessories
    • Welders and cutting torches, including the gas you use to operate them
    • Solvents, cleaners, degreasers, shop rags
    • Paint, even if used for production equipment
  • Office, maintenance, or janitorial equipment and supplies
  • Marketing, promotional, sales, or transportation equipment and supplies
  • Equipment and supplies to analyze or model financial results

Motor vehicles

Any motor vehicle that’s required to be licensed for use on public roads is taxable. This includes vehicles with restricted-use plates and recreational-use stickers.

Change Use of Exempt Item – Lumber Manufacturing

If you change the primary use of an item

If you buy an item exempt to use in a lumber manufacturing activity, it becomes taxable if you stop using it in a lumber manufacturing 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-lumber manufacturing activity, you can’t claim a tax credit if you begin to use it in a lumber manufacturing activity.

Buyer’s Responsibility – Lumber Manufacturing

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 don’t pay sales tax when you buy 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.

Sales by or to Lumber Manufacturers

Selling the lumber you manufacture

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 finished lumber to a contractor or employee
  • Selling finished lumber to buyers who don’t resell them
  • Selling firewood for bonfires or campfires
  • Selling equipment or promotional items to customers who don’t resell them

A retailer must get an Idaho seller’s permit, charge sales tax, file sales tax returns, and forward the tax to the Tax Commission.

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 lumber manufacturers

  • If you sell to lumber manufacturers, 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 lumber manufacturer in the future.

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

To be eligible for this exemption, your business must:

  • Engage in a qualifying lumber manufacturing activity. This includes manufacturing rough or finished lumber, such as sawmilling or lumber milling.
  • Devote the majority of your business operations to qualifying lumber manufacturing activities. Example: Spending more than 50% of the business’ working time and activities manufacturing rough or finished lumber.
  • Own the lumber you manufacture
  • Sell the lumber you manufacture
  • Report your business’ profit or loss on an income tax return.

Note: Custom sawmilling for someone else who owns the wood isn’t a qualifying activity.

Separately operated business segment

A separately operated business segment can also qualify. It can be a division, branch, or even a cost center. You must keep separate accounting records for the business segment to qualify as a separately operated business segment. This includes recording income, expenses, wages, and assets of the business segment separately. You must also have employees dedicated to operating the separate business segment.

Businesses that don’t qualify for the exemption

The lumber manufacturing exemption is only for businesses that devote the majority of their business operations to qualifying lumber manufacturing activities trying to make a profit.

  • It doesn’t include manufacturing of:
    • Plywood*
    • Particleboard*
    • Veneer*
    • Paper products*
  • Operations that aren’t eligible for the exemption include:
    • Lumber manufacturing as a hobby
    • Manufacturing lumber for personal use
    • Manufacturing lumber for use by your business

* Note: Although these manufacturing activities (plywood, particleboard, etc.) aren’t “lumber manufacturing,” they could qualify for the production exemption.
