Idaho Sales Tax on Precious Metals Bullion: Exemption Scope and Paperwork

Idaho does not charge sales tax on precious metals bullion. Idaho Code Section 63-3622V exempts qualifying bullion from the state’s 6% sales and use tax, with no minimum purchase amount, so a single silver round qualifies on the same footing as a $50,000 gold order.¹ The catch is that not every gold or silver product counts as bullion under the statute, and buying the wrong item means paying tax you didn’t expect.

How the Exemption Works

Section 63-3622V exempts qualifying bullion from “the taxes imposed by this chapter,” meaning Chapter 36 of Title 63 of the Idaho Code.¹ That chapter contains both the sales tax and the use tax.² So you pay no state tax when buying qualifying bullion from an Idaho dealer, and you owe no use tax when storing bullion in Idaho that you bought somewhere else.

There is no dollar floor. A $30 silver bar qualifies on the same terms as a six-figure gold order, as long as the item itself fits the statutory definition. Dealers are responsible for identifying exempt transactions correctly, but it is worth confirming the exemption at the counter rather than chasing a refund later.

Local Resort City Taxes

A handful of Idaho resort cities add a local sales tax on top of the state rate. These local taxes can only reach items that are already subject to the state sales tax.³ Because bullion is exempt at the state level, it falls outside those local levies as well.

What Counts as Bullion

The statute recognizes two categories: precious metal bullion and monetized bullion. Each has a specific definition, and items outside both are taxed like ordinary retail goods.

Precious Metal Bullion

Precious metal bullion means an elementary precious metal that has been smelted or refined and whose value depends on its metal content rather than its form. The statute specifically lists gold, silver, platinum, rhodium, and chromium.¹ Qualifying items include bars, rounds, and ingots stamped with weight and purity. The Idaho administrative code confirms that precious metal ingots are exempt.⁴

Idaho does not require a specific refiner or hallmark. The test is whether the price tracks the metal content. A generic silver bar selling near spot passes. A decorative silver figurine selling at three times melt value does not.

Monetized Bullion

Monetized bullion covers coins made from gold, silver, or other metals that serve or have served as a medium of exchange under the laws of the United States, a foreign nation, or Idaho itself.¹ American Gold Eagles, Canadian Maple Leafs, and South African Krugerrands all qualify, and the administrative code names Krugerrands by example.⁴

The hinge is legal tender status. A pre-1933 U.S. gold coin qualifies. A privately minted round with no face value is not monetized bullion, though it may still qualify as precious metal bullion if its value depends on metal content.

What the Exemption Does Not Cover

Several precious metal products stay fully taxable, even at high purity.

Jewelry. Belt buckles, bracelets, necklaces, and other wearables incorporating silver dollars, legal tender, or ingots are taxable. The exemption disappears the moment bullion becomes something you wear.⁴
Works of art. Coins or bullion sold to be manufactured into art lose the exemption. The statute draws the line at the point of sale: if the purpose of the transaction is creating artwork, it is taxable.¹
Commemoratives. Medallions, tokens, and coins created to commemorate a historical event are taxable regardless of their metal content.⁴

The dividing line is function. Bullion is valued for its metal. Jewelry is valued for appearance. Commemoratives are valued for collectible appeal. Idaho taxes the last two categories because they behave like retail consumer goods rather than raw investment metal.

Buying From Out-of-State and Online Dealers

Idaho’s use tax normally requires residents to pay 6% on tangible property purchased out of state and brought into Idaho for storage or use.² Because the bullion exemption reaches every tax imposed by Chapter 36, qualifying bullion bought from an out-of-state or online dealer and shipped into Idaho is also exempt.¹

You can buy gold bars from a dealer in another state, have them shipped home, and owe nothing in Idaho use tax. Items that do not qualify under the exemption, such as commemorative tokens or jewelry, would trigger the standard use tax if the out-of-state seller did not collect Idaho sales tax at the time of purchase.

Paperwork at the Counter

Idaho dealers selling exempt bullion need documentation on file to show the transaction qualified. The standard form is the Idaho Sales Tax Resale or Exemption Certificate, Form ST-101, available from the Idaho State Tax Commission.⁵

The form asks for your name, address, ZIP code, and either a federal EIN or driver’s license number. You then check the box for the exemption that applies. If the goods you are buying do not actually qualify for the exemption you claim, you become responsible for the unpaid tax, not the dealer. Fill it out carefully. Most established bullion dealers keep blank copies at the counter and can walk you through it.

What the Exemption Does Not Reach

The exemption is a state-level rule only. It stops at the Idaho sales and use tax; it has nothing to say about federal income tax when you later sell at a profit, or about the federal cash-reporting rules that apply to large transactions. Those are separate questions with separate answers, and bullion dealers can usually point you to the right paperwork when they come up.
