Sales Tax on Bullion in Missouri: The RSMo 144.815 Exemption and What It Really Covers

What RSMo 144.815 actually exempts

Missouri wrote its bullion exemption into statute in 2001, which placed it among the earlier adopters nationwide. The current operating text sits in Section 144.815 of the Revised Statutes of Missouri, under Chapter 144, Title X on taxation and revenue. The statute puts two categories outside the state and local sales tax when they meet specific statutory definitions.

• Bullion. Gold, silver, platinum or palladium in a bulk state, where value depends on content rather than form, with a purity of not less than 900 parts per 1,000. Refined bars, rounds, ingots and comparable forms sit squarely inside.
• Investment coins. Numismatic coins or other forms of money and legal tender manufactured of gold, silver, platinum, palladium or metals, where the fair market value exceeds the face value. American Gold Eagles, American Silver Eagles, Canadian Maple Leafs, Austrian Philharmonics, pre-1965 United States 90 percent silver coinage and graded numismatic coins all qualify when they are sold above face.

The statutory language is deliberate. “In a bulk state” rules out jewelry and worked art even if the underlying metal is 24-karat gold. The “fair market value greater than face value” test for coins captures the economic reality that an investment coin trades for its metal and collector premium, not its mint-stamped face. Translated for a Missouri dealer counter: if the sale is priced by weight and purity (bullion) or by premium over face (investment coin), the exemption applies. If the item is a wearable piece, scrap jewelry trade-in or display accessory, it is taxable retail.

Missouri enumerates all four of the common precious metals, which places it in the group of states that explicitly cover palladium alongside gold, silver and platinum. Buyers of palladium Maple Leafs, palladium American Eagles or palladium bars at or above 900 fineness receive the same treatment as buyers of gold or silver equivalents.

The 900 fineness threshold and why it matters

Missouri writes a hard purity floor into the bullion definition. The number is 900 parts per 1,000, or 90 percent fineness. Three practical consequences follow.

• Modern bullion is comfortably over the threshold. Standard refined bars and rounds commonly test at 0.999 or 0.9999 purity. Government-issue bullion coins vary: American Gold Eagles are 0.9167 pure (22-karat) and still clear 900, American Silver Eagles and Canadian Maple Leafs are 0.9999, Krugerrands are 0.9167, Gold Buffaloes are 0.9999.
• Pre-1965 United States 90 percent silver coinage sits exactly at the floor. Dimes, quarters, half dollars and dollars from that era are 0.900 fine silver. They qualify as investment coins when sold above face value on intrinsic silver content, which is how junk silver trades.
• Low-purity jewelry alloys fail. A 10-karat chain is 41.7 percent gold, a 14-karat band is 58.3 percent, an 18-karat ring is 75 percent. All three fall well below the 900 bullion threshold. Even if a jeweler sold a loose 24-karat bezel plate priced on weight, the jewelry form itself would still disqualify it from the “bulk state” bullion definition.

This purity test is different from the functional “intrinsic value” tests used by some southern states. Missouri’s rule is objectively measurable with an acid test, X-ray fluorescence or an electronic conductivity tester, which simplifies audits for both dealers and the Missouri Department of Revenue.

State and local: Missouri’s rare dual exemption

The quiet but important feature of RSMo 144.815 is that it removes bullion and investment coin purchases from both the state and local sales tax layers. Many state exemption statutes operate only on the state portion, leaving city and county add-ons to stack on top. Missouri’s statute specifically pulls these purchases out of the computation under Section 32.085 (local sales taxes), Sections 144.010 to 144.525 (state sales tax) and Sections 144.600 to 144.811 (use tax and related).

For a buyer in a jurisdiction with a 9.5 percent combined rate on general retail, this is the difference between paying 950 dollars of sales tax on a 10,000 dollar bullion order under a state-only exemption and paying zero under Missouri’s dual exemption. The effect compounds when the buyer lives in a high-rate city such as St. Louis, Kansas City or Springfield.

What this does not change: taxable items still carry the full combined state plus local rate. A gold wedding band sold next to the bullion on the same invoice remains fully taxable at the local combined rate, which can bring sticker shock in cities with aggressive local option taxes. The invoice should separate exempt and taxable line items so the math is transparent.

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

The exemption stops at qualifying bullion and investment coins. Everything else a Missouri precious-metals shop might ring up stays standard taxable retail at the combined state plus local rate.

The lines that confuse buyers most often involve coins that have been drilled, mounted or set into jewelry. A gold coin mounted in a bezel pendant becomes a jewelry item in the eyes of a Missouri retailer and sits outside the bullion-in-a-bulk-state definition. The exemption follows the economic character of the sale, not the raw metal content.

Missouri state and local rates at a glance

The Missouri Department of Revenue Sales and Use Tax portal publishes the operating structure. For taxable retail (jewelry, accessories, scrap) the layers stack as follows.

• State general rate: 4.225 percent. Split into General Revenue (3.0 percent), Education (1.0 percent), Conservation (0.125 percent) and Parks and Soils (0.1 percent). The use tax rate matches at 4.225 percent on taxable property stored, used or consumed in Missouri.
• Local option sales tax. Cities, counties and special districts can impose their own layers. Combined rates on taxable retail typically land between 7 and 10 percent in populated areas, with pockets lower in rural counties and higher in some special taxing districts. The Missouri DOR maintains the current rate tables by jurisdiction.
• Reduced grocery rate. Missouri taxes qualifying groceries at a reduced state rate under Section 144.014, but this does not apply to bullion, coins, jewelry or any precious-metals retail.

For a bullion buyer the local variation is academic because qualifying purchases carry zero sales tax statewide. For a jewelry buyer, the combined rate is worth confirming before purchase: a 2,000 dollar 14-karat band taxed at a 9.6 percent combined rate costs 192 dollars in sales tax, while the same purchase at a 7.1 percent combined rate costs 142 dollars. The Missouri DOR address lookup tool resolves rates to the specific shipping address.

Online, in-store and out-of-state: who collects, who self-reports

After the United States Supreme Court decision in South Dakota v. Wayfair (2018), out-of-state retailers with enough Missouri sales must register and collect Missouri sales and use tax on shipments to Missouri addresses. Missouri’s economic nexus and marketplace facilitator rules took effect on January 1, 2023 under Senate Bill 153 (2021). The substance of RSMo 144.815 did not change, but the question of who writes the check moved for taxable items.

• Qualifying bullion or investment coins shipped from any state to Missouri: no state and no local sales tax under Section 144.815. Well-run national dealers configure their carts to zero out the tax line on qualifying SKUs when the ship-to address is in Missouri.
• Non-qualifying items shipped to Missouri (jewelry, scrap resale, display accessories, mounted coins): the seller typically collects state and local use tax at checkout for Missouri customers, or the buyer self-reports the matching use tax on their Missouri return.
• In-person purchase at a Missouri coin shop: same substantive rules. Qualifying products are exempt at the register, taxable items carry the combined state plus local rate for the shop’s address.
• Taxable item bought in person out of state and brought home: the Missouri resident technically owes matching Missouri use tax under RSMo 144.610, with a credit for sales tax properly collected at the origin.

If a line labeled “sales tax” appears on an invoice for a 1 oz American Gold Eagle shipped to a Missouri address, point the dealer to Section 144.815 and ask for a corrected invoice. Dealers who have not refreshed their rate tables will usually correct the entry quickly once the statute is cited directly. Recovery from the Missouri Department of Revenue on a wrongly collected tax paid to a third party is a slower, paperwork-heavy path.

Practical scenarios: what a Missouri buyer actually pays

Three worked examples. State rate 4.225 percent plus illustrative local rates on taxable items only.

1. St. Louis coin shop, 10,000 dollar order of 1 oz American Gold Eagles. Sales tax owed: 0 dollars. The coins are investment coins under RSMo 144.815, exempt from both the state and St. Louis city plus county layers.
2. Same shop, 2,000 dollar order of 14-karat gold jewelry. Taxable retail at the combined St. Louis rate, which commonly lands in the 9 to 10 percent range depending on the exact storefront address. On a 2,000 dollar order that is between 180 and 200 dollars of sales tax collected at the register and remitted to Missouri DOR.
3. Online dealer in Delaware ships a 5,000 dollar order of pre-1965 US silver quarters plus a 1,500 dollar order of jewelry-mounted coin pendants to a Springfield address. Pre-1965 silver quarters: 0 dollars, investment coins exempt under Section 144.815. Jewelry-mounted coin pendants: use tax at the combined Springfield rate, typically around 8 percent, so approximately 120 dollars collected by the dealer at checkout.

The takeaway. For a stacker buying qualifying bullion or investment coins, Missouri is a true zero-tax state at the register and at the door for shipments. For jewelry or accessory purchases, the combined state plus local rate matters and varies by jurisdiction.

Record-keeping and audit exposure

Keep the invoice for every precious-metals purchase, whether tax was collected or not. The invoice should identify each line item by product, weight and purity, and should show either a zero tax line or a clear notation of the Section 144.815 exemption on qualifying items. If a dealer refuses to itemize, or lumps taxable and exempt items into a single subtotal, that is a signal to walk.

For dealers and shop owners the bar is higher. The Missouri Department of Revenue can audit sales and use tax returns and expects documentation on which line items qualified for exemption and why, especially on mixed invoices where jewelry sits next to bullion. Resale exemption certificates, invoices that identify metal and form, and a point-of-sale configuration that separates bullion SKUs from jewelry and accessory SKUs keep audits routine. Shops that updated their systems promptly after the 2001 effective date have operated under this regime for more than two decades and generally handle audit requests without friction.

The 2001 reform in context

Missouri enacted its bullion and investment coin exemption through Senate Bill 896 in the 2000 legislative session and House Bill 825 in 2001, with the final effective date of August 28, 2001. That timing put Missouri more than a decade ahead of states such as Minnesota, Mississippi and others that passed exemptions in the 2010s or 2020s. The policy argument tracked the one made in Texas, Oklahoma and later in Kansas: bullion and investment coins are investment instruments that compete with stocks, bonds and exchange-traded funds. Taxing a direct retail purchase of a 1 ounce silver round while leaving an electronic silver ETF share tax-free put the physical buyer at an artificial disadvantage.

Missouri’s statutory design has two distinctive features worth flagging. First, the dual state and local exemption. Second, the explicit purity threshold at 900 parts per 1,000. The first improves economic alignment with investment intent across every jurisdiction in the state. The second gives dealers a bright-line test they can apply at the counter with a standard precious-metals assay, which cuts enforcement cost compared with purely functional “intrinsic value” tests.

How Missouri compares to its neighbors

Missouri borders eight states. Treatment of bullion and investment coins varies across that ring, but the overall picture is favorable:

• Illinois: exempts legal tender bullion and gold or silver coinage under its own statutory framework, with Chicago area combined rates on taxable items among the highest in the Midwest.
• Kansas: enacted a precious-metals bullion exemption in 2019 under Senate Bill 90, moving Kansas into the exemption column after Missouri had been there for nearly two decades.
• Iowa: exempts the sale of coins, currency and precious-metal bullion when sold on intrinsic value, closer to the Mississippi functional test than to the Missouri purity threshold.
• Nebraska: exempts currency and bullion sales under its own code with specific statutory references and definitions.
• Oklahoma: exempts sales of gold, silver, platinum and palladium bullion and numismatic coins under 68 OS Section 1357.
• Arkansas: exempts gold and silver coins and bullion with specific statutory references.
• Tennessee: exempts coins, currency and bullion sales under its 2022 reform.
• Kentucky: enacted a bullion and currency exemption in 2024 under House Bill 8, closing one of the last gaps in the Mississippi River corridor.
• Federal treatment: entirely separate. 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.

For a Missouri buyer within reasonable driving distance of a border state, the state-level treatment of qualifying bullion is close to a wash across the entire ring. Local sales tax rates on taxable items (jewelry, accessories) and travel economics dominate the decision far more than the bullion rules themselves.
