The rules that decide which metals an IRA can own are short, but they are written in tax-code language. Here is what they say and what they mean for you. The full detail sits in our gold IRA rules guide; this is the recap you need to choose products.
The starting point: collectibles are banned
Section 408(m) of the Internal Revenue Code (26 U.S.C. 408) says that if an IRA buys a "collectible," the purchase is treated as a distribution to the account owner. Collectibles include art, antiques, gems, stamps, alcoholic beverages - and "any metal or coin." So by default, gold coins and bars are not allowed. The IRS repeats this in Publication 590-A, its guide to contributing to IRAs.
A "distribution" is not just a technicality. It means the money you spent can be taxed as ordinary income in that year, and if you are under 59½, the 10% additional tax on early withdrawals can apply too. On a $50,000 purchase, that could be a five-figure tax bill.
Exception 1: certain US government coins
The law then carves out exceptions. The first covers specific coins minted by the US Treasury, including:
- American Gold Eagles (1 oz, 1/2 oz, 1/4 oz and 1/10 oz)
- American Silver Eagles
- American Platinum Eagles
- Certain coins issued under the laws of a US state
This is a statutory exemption: these coins are allowed because Congress named them, not because of their purity. That is why the Gold Eagle is allowed even though it is 22-karat gold (.9167 fine), well below the .995 standard that applies to everything else. It is also why proof versions of the American Eagle are widely treated as eligible: the exemption describes the coin, and the US Mint strikes proofs under the same authority. Custodians generally accept Eagle proofs. Whether a proof is a good buy is a separate question, which we cover in the proof coin section.
Exception 2: bullion meeting futures-contract fineness
The second exception covers bullion - coins, bars and rounds - that is at least as pure as the minimum fineness required for metal delivered against a regulated futures contract, and is in the physical possession of the IRA trustee. In practice that means:
| Metal | Minimum fineness | What it means |
| Gold | .995 (99.5% pure) | American Eagle exempt by statute despite being .9167 |
| Silver | .999 (99.9% pure) | American Silver Eagle also named in the statute |
| Platinum | .9995 (99.95% pure) | American Platinum Eagle also named in the statute |
| Palladium | .9995 (99.95% pure) | Includes the American Palladium Eagle and qualifying bars |
This is why the Canadian Maple Leaf (.9999), Austrian Philharmonic (.9999), American Buffalo (.9999) and modern Britannia (.9999) are all eligible, while the South African Krugerrand (.9167) is not.
Exception 2 has a second condition: the trustee must hold it
The bullion exception only works if the metal is "in the physical possession" of the IRA's trustee or custodian. That is why IRA gold sits in a depository arranged by your custodian, and why "home storage" schemes have failed in court. In McNulty v. Commissioner, 157 T.C. No. 10 (2021), the Tax Court treated coins kept at home through an "IRA LLC" as taxable distributions, with penalties on top. Our article on storing IRA gold at home covers that case in detail.
Accredited refiners: a custodian rule, not a tax rule
You will often hear that bars must come from an "accredited" refiner - one approved by NYMEX/COMEX or the LBMA (the London Bullion Market Association). The tax code itself only sets the fineness standard. The refiner requirement is a custodian and depository policy: most custodians will only accept bars from recognized refiners, because those bars are easy to verify and resell. Treat it as a practical rule. If your custodian will not accept a bar, you cannot hold it, whatever the tax code says.
What is not eligible
| Product | Why it fails |
| South African Krugerrand | .9167 fine and not covered by the US coin exemption |
| British gold Sovereign | .9167 fine |
| Pre-2013 British Britannias | Struck at .9167 (22 karat) before the Royal Mint switched to .9999 |
| Pre-1933 US gold coins (e.g. $20 Double Eagles) | .900 fine; also collector coins |
| Mexican 50 Pesos | .900 fine |
| Graded "rare" or numismatic coins | Collectibles; generally not eligible unless the coin itself is an exempt US Eagle |
| Gold jewelry | Collectible, not bullion |
The practical rule is simple. Before you buy anything, ask your custodian - not the dealer - to confirm in writing that the exact product is accepted for your IRA. Custodians are the ones who report the account to the IRS, so they have every reason to get this right. Our guide to gold IRA custodians explains their role.
A word on "IRS-approved"
You will see the phrase "IRS-approved coins" everywhere, including in the title of our own eligibility guide. It is shorthand for "eligible under the tax code." The IRS does not approve, certify or endorse any dealer, company or individual coin. If a salesperson calls their firm "IRS-approved," that is a red flag, not a credential. The CFTC, FINRA and NASAA joint advisory, "10 Things to Ask Before Buying Physical Gold, Silver, or Other Metals," is worth reading on exactly this kind of claim.
