Sales Tax on Bullion in Idaho: What Buyers, Sellers and Dealers Owe

What Idaho actually exempts under Section 63-3622V

Idaho is among the broad-exemption states for physical precious-metals buyers. The operative statute is Idaho Code Section 63-3622V, Precious Metal Bullion and Monetized Bullion, administered by the Idaho State Tax Commission under Title 63, Chapter 36 (Sales Tax). The section carves two categories out of the taxable base, defined inside the statute itself:

• Precious metal bullion. Any elementary precious metal that has been put through a process of smelting or refining, including gold, silver, platinum, rhodium and chromium, whose value depends on its contents and not on its form. Refined bars, rounds and ingots priced off the spot market sit here.
• Monetized bullion. Coins or other forms of money manufactured from gold, silver or other metals that have been used or are used as a medium of exchange under the laws of Idaho, the United States or any foreign nation. American Gold Eagles, Silver Eagles, Canadian Maple Leafs, Austrian Philharmonics, South African Krugerrands and pre-1965 US silver coinage sit here.

One carve-in runs through both definitions: the exemption does not reach coins or money sold specifically to be manufactured into jewelry or works of art. In practice, dealers who sell both to stackers and to jewelers keep that line of business invoiced separately so the taxable channel does not contaminate the exempt channel at audit time.

Two Idaho details are worth flagging up front. First, the statute names chromium alongside the usual precious metals. Chromium is unusual in state bullion statutes and reflects the “but not limited to” open-list drafting Idaho used. Second, palladium is not named. The statute uses “including, but not limited to,” which gives dealers some room, but Idaho enforcement practice has historically treated palladium bullion as taxable retail. Buyers should expect the 6 percent state rate on palladium at an Idaho shop and ask for the dealer’s exemption position in writing if a large order is in play.

What still gets taxed: jewelry, palladium and the borderline cases

The exemption stops at refined bullion and monetized coins. Everything else that a precious-metals shop might ring up is standard taxable retail:

Two lines trip up Idaho buyers most often. Palladium is the first: multi-metal stackers assume it rides on platinum, but the Idaho statute names platinum and omits palladium, and the enforcement practice has followed that letter. The second is the jewelry carve-in on raw metal. A one-ounce gold round sold to a stacker over the counter is exempt. The same round sold to a local goldsmith who tells the dealer it is destined for a wedding band is a taxable sale. The invoice language and the SKU setup matter, which is why experienced Idaho shops keep bullion and jewelry inventory on separate registers.

Finished jewelry gets the second mention. A 24-karat pendant is metallurgically identical to a one-ounce bar of the same weight, but once metal takes a jewelry form (chain, bracelet, ring, wearable art) it stops being bullion in the eyes of the Idaho State Tax Commission and becomes standard taxable retail at 6 percent.

How Idaho sales tax rates actually stack

Idaho’s base is simpler than the Texas or Arizona layer cakes. The Idaho State Tax Commission Sales and Use Tax page publishes the current base:

• State rate: 6 percent on retail sales, leases and rentals of most tangible personal property.
• Use tax: 6 percent on the same base, applied when a taxable item was bought elsewhere without Idaho tax.
• Local option: resort cities only, approved by local voters and capped by state law.

Idaho does not have the broad city or county add-ons that stack on top of the state rate in other states. Instead, under Idaho Code Section 50-1044, voters in a qualifying resort city (and separately in auditorium districts) can approve a local-option sales tax. The Idaho State Tax Commission’s resort city page lists 23 cities that have adopted one: Bellevue, Bonners Ferry, Cascade, Crouch, Donnelly, Driggs, Hailey, Harrison, Irwin, Kellogg, Ketchum, Lava Hot Springs, Mackay, McCall, Ponderay, Riggins, Salmon, Sandpoint, Stanley, Sun Valley, Swan Valley, Tetonia and Victor.

Each resort city sets its own scope. Many limit the local tax to hospitality lines (lodging, alcohol by the drink, restaurant food), which keeps bullion outside the local base. Others are broader. A buyer purchasing coins at a shop inside a resort city should ask the dealer to confirm the local treatment at the register and verify the current scope on the resort city’s own ordinance page before placing a large order.

Online vs in-store: the rules do not change, but who collects can

Since the US Supreme Court decision in South Dakota v. Wayfair (2018), out-of-state online retailers with enough Idaho activity must register with the Idaho State Tax Commission and collect sales and use tax on shipments to Idaho addresses. That did not change the substance of Section 63-3622V, but it did change who writes the check.

• Eligible bullion or monetized coin shipped from any state to Idaho: not taxable. Well-run national dealers configure their checkout to zero out the tax line on these SKUs for Idaho addresses.
• Non-exempt item (jewelry, palladium, accessories) shipped to Idaho: the seller typically collects 6 percent at checkout, or the buyer self-reports use tax on their Idaho return.
• In-person purchase in an Idaho coin shop: same substantive rules. A resort-city add-on may apply only if the city’s local-option scope reaches bullion, which is uncommon.

Some out-of-state dealers still get the exemption wrong on Idaho orders. If you see a line labeled “sales tax” on eligible bullion or monetized coins shipped to an Idaho address, ask the dealer to correct the invoice and cite Section 63-3622V. Do not pay the erroneous tax and then try to recover it from the Idaho State Tax Commission: refund claims from the state on tax collected by a third party are a slow, paperwork-heavy path.

Buying out of state and bringing it home: use tax reality

Use tax is the mirror image of sales tax. When an Idaho resident buys taxable goods somewhere else (in person or by mail) and no Idaho tax was collected, they owe the same 6 percent on that purchase, reported on their Idaho tax return or through the Commission’s Taxpayer Access Point.

For exempt bullion and monetized coins, the use tax is zero because the sale itself would be zero in Idaho. For taxable items brought back from a Nevada, Oregon or Wyoming dealer (jewelry, palladium, copper products), the Idaho resident technically owes 6 percent in Idaho, net of any sales tax paid at the point of sale. Individual enforcement on personal-scale purchases is uncommon, but dealers and repeat-volume buyers are correctly viewed as reporting obligations by the Commission.

Practical scenarios: what an Idaho buyer actually pays

Two worked examples at the 6 percent state rate:

1. Boise coin shop, $10,000 order of 1 oz American Gold Eagles. Sales tax owed: $0. The coins qualify as monetized bullion and gold bullion under Section 63-3622V and are exempt. The buyer leaves with 10 coins at today’s dealer premium over spot. Spot checks for Idaho buyers run through our gold value calculator rather than any third-party chart.
2. Same shop, $2,000 order of 22-karat gold jewelry. State tax: $120 (6 percent). Local tax: $0 at a Boise shop (Boise is not a resort city). Total: $120 owed at checkout. If the same order ran at a shop in a resort city whose local-option scope reaches retail goods, add that local rate on top; most resort cities keep the local base to hospitality only, so most Idaho jewelry sales still see only the 6 percent state line.

The takeaway for a buyer building a stack of qualifying bullion and monetized coins: Idaho is effectively a zero-sales-tax state. For a buyer picking up palladium or jewelry alongside, the tax line on the mixed portion of the invoice is predictable and small compared with the Mountain West peer states that layer 8 percent or 9 percent combined rates on the same jewelry.

Record-keeping and audit exposure

Retail buyers should keep the invoice for every precious-metals purchase, whether tax was collected or not. The invoice should show the item description, quantity, price and, for exempt items, either a zero tax line or a clear notation of the Section 63-3622V exemption. If a dealer refuses to itemize or lumps taxable and exempt items into a single subtotal, that is a red flag on both sales-tax compliance and general shop transparency.

For dealers and shop owners the record-keeping bar is higher. The Idaho State Tax Commission can audit sales and use tax returns under the statute of limitations in Title 63, Chapter 36 and expects contemporaneous documentation showing which line items were exempt and why. Resale certificates, invoices that identify the metal and form, and a clean point-of-sale configuration that separates bullion SKUs from accessory and jewelry SKUs make audits routine rather than expensive. Dealers running a resort-city storefront should also keep clear records of which items fell inside the local-option base versus outside it.

How Idaho compares to the neighboring states

Idaho is not alone in exempting bullion, but the specifics vary widely across the Mountain West:

• Washington: previously exempted precious metal bullion for years, then repealed the exemption effective January 1, 2026. Bullion is now taxable at the standard Washington combined rate. A full map of state-by-state status, including the Washington change, lives in our sales tax on bullion by state hub.
• Oregon: no state sales tax at all, so bullion, jewelry and accessories all ring up tax-free at retail.
• Nevada, Utah, Wyoming, Montana: each run a different mix of exemption, threshold and rate. Cross-border shipments are governed by the delivery state’s rules, not the seller’s.
• Federal treatment: completely separate. Regardless of state sales tax, physical gold and silver held more than one year are federally taxed as “collectibles” at up to 28 percent on realized long-term capital gains under IRC Section 1(h)(4). Our capital gains guide walks through the mechanics.

An Idaho resident who drives to Oregon to buy jewelry can end up ahead on the Oregon side (no sales tax there), subject to the Idaho use-tax rule on the return trip. For pure bullion the answer flips: Idaho is already tax-free on qualifying coins and bars, so there is nothing to save by crossing a state line.
