Selling Gold in Idaho: Taxes, Dealer Rules and How to Prepare

Sales Tax in Idaho on Investment Gold: Exempt Under 63-3622V

Idaho’s statewide sales tax rate is 6 percent, with a small average local component of about 0.03 percent that reaches up to 3 percent in a handful of resort cities, according to the Tax Foundation state and local sales tax ranking. On precious metals, the operative provision is Idaho Code 63-3622V, which exempts “the sale of precious metal bullion or the sale of monetized bullion” from the taxes imposed by Idaho’s Sales Tax Act (Title 63, Chapter 36).

Two definitions in the statute do the work:

• Precious metal bullion: “any elementary precious metal which has been put through a process of smelting or refining including, but not limited to, gold, silver, platinum, rhodium, and chromium, and which is in such state or condition that its value depends upon its contents and not upon its form.” That language reaches refined gold and silver bars, rounds and ingots whose price tracks the underlying metal rather than numismatic form.
• Monetized bullion: “coins or other forms of money manufactured from gold, silver, or other metals and heretofore, now, or hereafter used as a medium of exchange under the laws of this state, the United States, or any foreign nation.” American Gold Eagles, American Silver Eagles, Canadian Maple Leafs, South African Krugerrands and other sovereign bullion coins fall squarely inside this definition. Collectible numismatic coins that still carry legal-tender status also qualify as monetized bullion.

The statute carves out one exception from the exemption: “coins or money sold to be manufactured into jewelry or works of art.” A coin melted down for jewelry stock is a different transaction from a coin bought as money, and Idaho taxes the first and not the second.

Why There Is No Sales Tax on a Private Sale to an Idaho Dealer

If you walk into a Boise, Meridian, Nampa, Idaho Falls, Pocatello, Coeur d’Alene, Twin Falls or Lewiston buyer and sell personal gold, the transaction is you parting with metal for cash. Idaho sales tax is imposed on the retail sale of tangible personal property by a seller to a buyer, and 63-3622V exempts the specific category of precious-metal bullion and monetized bullion from that regime altogether. Even if you were operating as a dealer and not a private seller, the same exemption would apply on the metal side.

Where the exemption does not reach is a dealer’s downstream resale of refined jewelry or karat gold that no longer qualifies as bullion. If your lot includes a wedding band or scrap chain and the dealer resells that jewelry to a retail customer, the 6 percent state rate (plus any local option tax) applies to that resale ticket. That is the dealer’s problem on the resale leg, not yours when you sell. For a buyer-side breakdown of sales tax exposure on bullion delivered to Idaho buyers, see our companion piece on sales tax on bullion in Idaho.

Dealers Who Try to Deduct Sales Tax From Your Offer

Because 63-3622V exempts the transaction, an Idaho buyer has no basis to deduct a sales-tax amount from the price offered on your coins or bars. If you see “state sales tax” or “6 percent tax” as a negative line on a buy-side quote, that is a mislabeling of the buyer’s own cost of doing business, not a lawful adjustment to a seller. Ask for the exemption citation and move on if the dealer cannot provide one. The Idaho State Tax Commission publishes exemption guidance at tax.idaho.gov sales and use exemptions.

Idaho Income Tax on Gold Gains: Flat 5.3 Percent, No Bullion Carve-Out

Idaho taxes individual income on Form 40 at a flat statewide rate. Under House Bill 40 (2022) and subsequent rate reductions, the Idaho rate dropped from a graduated structure to a single flat rate: 5.8 percent in 2023, then phased down. The Idaho State Tax Commission publishes the current rate as 5.3 percent on Idaho taxable income for 2025, and the Tax Foundation 2026 state income tax data confirms Idaho’s single-rate structure at 5.3 percent for 2026. Verify the current year’s rate on the Tax Commission site before filing.

Capital Gain Is Taxed as Ordinary Income

Idaho does not have a preferential rate for long-term capital gain. Any gain reported on your federal Schedule D flows into Idaho taxable income and is taxed at the same flat 5.3 percent as wages, interest or rental income. Short-term and long-term federal classification only matters for the federal rate, not for the Idaho rate.

The Idaho Capital Gains Deduction (63-3022H) Does Not Reach Bullion or Coins

Idaho Code 63-3022H allows resident filers a deduction of 60 percent of net capital gain from the sale of qualifying Idaho property, computed on Form CG. The qualifying property list is finite and specific:

• Idaho real property held at least 12 months (18 months for sales before January 1, 2005)
• Idaho tangible personal property used in a revenue-producing enterprise and held 12 months or more
• Cattle and horses used for breeding, draft, dairy or sporting purposes and held 24 months or more
• Other breeding livestock held 12 months or more
• Timber grown in Idaho and held 24 months or more
• Qualifying partnership interests held 12 months or more

Investment bullion coins and bars sit outside every category. They are not real property, not a revenue-producing business asset for a private holder, not livestock and not timber. Dealer inventory used in a revenue-producing precious-metal business can qualify as revenue-producing tangible personal property, but that treatment is for the business, not for a private seller of personal holdings.

Several other states (roughly a dozen as of 2024) have enacted narrow exclusions that take the gain or loss on legal-tender precious-metal coins off the state income tax base. Idaho has not enacted such an exclusion as of this writing, and legislative proposals to broaden the capital gains deduction to bullion have not become law. If a reader is told a sale is “state income tax free in Idaho,” ask for the statute citation. For most private sellers, the Idaho line of attack is simply the flat 5.3 percent on net gain.

Federal Collectibles Capital Gains Rules (Apply First)

The IRS classifies physical gold, silver, platinum and palladium as collectibles under 26 U.S. Code 408(m), and 26 U.S. Code 1(h)(4) caps the federal long-term capital gains rate on collectibles at 28 percent, higher than the 0, 15 or 20 percent rates that apply to most stock and bond gains. Short-term gain is taxed at your ordinary federal rate. See IRS Topic 409 for the mechanical rules. For a deeper walk-through of the ceiling, see our guide to the 28 percent collectibles rule.

Calculating Your Taxable Gain

Gain is computed federally and then flows to Idaho:

• Start with the sale price received from the Idaho buyer.
• Subtract your cost basis: original purchase price plus documented acquisition costs (dealer premiums, shipping, insurance, assay fees).
• Report the net gain federally on Schedule D and Form 8949 under collectibles treatment, and carry the resulting federal taxable income to Idaho Form 40 (resident) or Form 43 (nonresident or part-year).
• Apply the flat 5.3 percent Idaho rate to Idaho taxable income after federal flow-through.

Keep purchase receipts, dealer invoices, shipping records and assay certificates for every bullion acquisition. To estimate what your current holdings are worth per weight and purity before you model tax, use the Goldiew gold value calculator, which pulls a live spot price.

A Worked Example (Illustrative Only)

The figures below are illustrative, assume a long-term federal holding treated under the collectibles rules, and assume Idaho resident filing on Form 40. Your actual liability depends on total income, filing status, deductions and other factors. Consult a licensed Idaho CPA before acting.

The federal collectibles rate dominates the combined bill. Idaho’s flat 5.3 percent lands in the mid-pack of states and is noticeably below neighboring Oregon’s top 9.9 percent bracket on comparable gain, but above Nevada and Washington’s zero-rate treatment of individual wage and gain income (both of those states still tax other things).

Idaho Dealer Rules: Scrap Metal Businesses Under Title 54, Chapter 27

Idaho’s state-level framework for buyers of metal is Idaho Code Title 54, Chapter 27, the Scrap Metal Businesses Act, codified at sections 54-2701 through 54-2706 and reproduced at codes.findlaw.com Idaho Title 54 Chapter 27. The chapter regulates “scrap metal businesses” that purchase or receive nonferrous metal property, including gold, silver, platinum, rhodium and palladium, “for the purpose of aggregation and sale to other scrap businesses” or for processing into feedstock.

Traditional precious-metal buyers and jewelers that purchase for resale as jewelry or as recognized bullion, rather than for scrap aggregation, generally fall outside the Chapter 27 scope. For those buyers, Idaho relies on municipal licensing: cities such as Boise, Meridian, Nampa, Coeur d’Alene and Idaho Falls each publish their own business-license and secondhand-dealer or pawnbroker ordinances. Verify the current municipal code at the city clerk’s office before relying on any specific threshold.

Record-Keeping Under 54-2702

Every scrap-metal business must keep a written record, in English, on a standardized or electronic form, retained for five years, for every transaction involving nonferrous metal or stainless steel. The record must include: date, location and value of the transaction; employee name representing the business; the seller’s signature; the seller’s driver’s license or other government-issued photo ID (a photocopy or image); the vehicle license plate number if applicable; and a signed statement that “the property that is subject to this transaction is not to the best of my knowledge stolen property.” An employee must witness the declaration.

The statute also requires a digital photo, photograph or video image of “the person, property and vehicle involved” for the first three purchases from any individual within a one-year period. Subsequent purchases from the same person inside that twelve-month window are exempt from the imaging requirement, though the full ID and signature workflow continues.

Identification Required Under 54-2703

Idaho Code 54-2703 forbids a scrap-metal business from “transacting with sellers lacking proper identification as referenced in section 54-2702(1)(e).” For commercial metal property, the seller must maintain a commercial account, provide ownership documentation, or produce written documentation of agency to sell on behalf of a commercial enterprise. Burned wire requires written proof that the wire was lawfully burned or recovered. Beer kegs require authorization from the distributor, manufacturer or licensed brewery.

Commercial Account Records Under 54-2704

For commercial accounts, 54-2704 requires permanent records retained for at least five years, including the enterprise’s full name, business address, telephone number and authorized contacts for both delivery and possession. Payment on a commercial account may be made by cash, credit card, electronic funds transfer or check payable to the commercial enterprise. The statute does not impose a general cash-payment ban at the state level.

Law Enforcement Access Under 54-2705

Idaho Code 54-2705 requires every scrap-metal business to make its records available to a chief of police or county law enforcement officer on request, within at least five business days, electronically, by fax, by modem or on computer disk, or in person at a mutually convenient time. The requirement reaches “a full, true, and correct record from the purchase or receipt of nonferrous metal property or stainless steel involving a specific individual, vehicle, or item,” subject to the five-year retention period.

What This Means for a Private Seller

If you walk a lot of coins, bars and jewelry into a dedicated precious-metals buyer in Boise or Idaho Falls that resells those items in the same form, you are typically outside Title 54 Chapter 27 and the dealer runs a municipal workflow instead. If you walk the same lot into a scrap-metal business that will melt and aggregate the metal for sale downstream, the Chapter 27 record-keeping, ID requirement and (on the first three annual purchases) photo or video intake kick in. Both operations are legitimate. A buyer that resists either workflow, that refuses to show a current municipal license where one applies, or that refuses to document the transaction in writing is not operating within the Idaho framework.

Step by Step: How to Prepare Before Selling Gold in Idaho

A short preparation window before you walk into a dealer in Boise, Meridian, Nampa, Idaho Falls, Pocatello, Coeur d’Alene, Twin Falls, Lewiston, Caldwell, Post Falls, Rexburg, Moscow or any Idaho community measurably improves what you take home.

1. Gather Your Cost Basis Documentation

Pull together original purchase invoices, dealer receipts, shipping and insurance records, and any assay certificates. The stronger your documentation, the lower your federal taxable gain and the lower the amount Idaho taxes at the flat 5.3 percent rate. If you inherited the metal, document its fair market value at the time of inheritance (stepped-up basis under federal rules; Idaho follows for Form 40 purposes).

2. Verify the Spot Price Internally First

Before approaching any Idaho buyer, know the day’s spot price. The simplest way is the Goldiew gold value calculator, which pulls a live spot so you can estimate holdings by weight and purity. The spot number lets you judge whether a dealer’s offer is in line with current market conditions.

3. Weigh and Test Your Items at Home

A basic jewelry scale that reads in grams and troy ounces confirms weight. Purity markings (10K, 14K, 18K on jewelry; 0.999 or 0.9999 on bullion) indicate fineness. For items without clear markings, a reputable Idaho dealer offers an on-site acid test or XRF scan. Watch the test being performed; a dealer who refuses to let you observe is a red flag.

4. Get Multiple Offers

Dealer spreads vary across Idaho, especially between the Treasure Valley cluster (Boise, Meridian, Nampa, Caldwell) and the Eastern Idaho / North Idaho cities. Two or three competing offers typically improve what you receive, especially on larger holdings. The simplest way to do this at scale is to post one free request on Goldiew’s Sell Gold platform, which routes to up to 15 verified buyers in sealed-offer form. See also why getting multiple offers matters.

5. Confirm the Workflow Your Buyer Operates Under

Ask the dealer at the counter which Idaho framework applies to your lot. A dedicated precious-metal or jewelry buyer that resells your metal in the same form operates under municipal licensing in Boise, Meridian, Nampa, Coeur d’Alene, Idaho Falls or the city where the shop sits, with ordinance-specific record-keeping. A scrap-metal buyer that aggregates for downstream sale operates under Title 54 Chapter 27, with the signed no-stolen-property statement, photo-ID copy and (for the first three annual purchases from you) a photo or video of the transaction. A buyer that cannot answer which framework applies is worth skipping.

What a Legitimate Idaho Buyer Looks Like (and Red Flags)

A legitimate Idaho precious-metals buyer typically shares the following traits:

• A current municipal business license and (where the city requires one) a secondhand-dealer or pawnbroker endorsement, visibly posted at the premises.
• If operating as a scrap-metal business under Title 54 Chapter 27: a visible intake process that captures government-issued photo ID, the no-stolen-property signed declaration and (on first-time or early-year sellers) a photo or video of the transaction.
• A permanent Idaho street-address location with regular hours, not a hotel-conference pop-up or a traveling van.
• A clear written offer tied to the current spot price and a transparent weighing and testing methodology.
• Willingness to let you observe weighing and acid or XRF testing in real time.
• A written receipt itemizing each piece purchased and the price paid, matching the record retained by the dealer.
• No attempt to deduct a 6 percent “sales tax” from your buy-side price (sales to a buyer are exempt under 63-3622V).
• Verifiable community reviews on at least one independent platform.

Red flags that warrant walking away: pressure to decide on the spot, refusal to provide a written offer, refusal to show a current municipal license, dramatically below-spot offers framed as limited-time deals, and buyers operating from temporary venues.

Special Situation: Gold Held in a Self-Directed IRA

If your gold is held inside a properly structured self-directed IRA, selling it inside the IRA is not a taxable event. Taxes apply when you take distributions: traditional IRA distributions are taxed as ordinary federal income and as ordinary Idaho income at the flat 5.3 percent rate on Form 40, while qualified Roth distributions are federally tax-free, and Idaho conforms. The federal collectibles cap does not apply, because the distribution itself is ordinary income. See IRS Publication 590-B for distribution mechanics.
