IRS purity requirements, side by side
| Metal | Minimum fineness | Common IRA-eligible forms |
|---|---|---|
| Gold | 99.5% | American Eagle (exempted from the purity rule by name), Canadian Maple Leaf, approved bars |
| Silver | 99.9% | American Eagle, Canadian Maple Leaf, approved bars |
| Platinum | 99.95% | American Platinum Eagle, Canadian Platinum Maple Leaf, approved bars |
| Palladium | 99.95% | Canadian Palladium Maple Leaf, approved bars |
Purity thresholds per 26 U.S. Code § 408(m)(3). Collectible/numismatic and proof coins not meeting these standards, and coins/bars from non-approved refiners, are not IRA-eligible regardless of metal content.
Why so few people actually hold these two
Three practical reasons platinum and palladium stay niche inside precious-metals IRAs, even though they’re legal:
1. Thinner market, wider spreads
Far less platinum and palladium bullion is minted and traded than gold or silver, so dealer bid/ask spreads tend to run wider, and buyback liquidity is less certain when you eventually want to sell or take a distribution.
2. Industrial-demand price swings
Platinum and palladium are heavily used in catalytic converters and other industrial processes, so their prices move more with auto-manufacturing and industrial-demand cycles than gold’s, which trades more on monetary/safe-haven demand. That makes them behave less like a “crisis hedge” and more like an industrial commodity with a monetary side use.
3. Fewer approved products
The list of coins and bars that clear both the purity bar and an approved refiner/mint requirement is shorter than for gold or silver, which narrows what a custodian can actually source and hold for you.
How to actually add either to an IRA
The mechanics don’t require a separate account type. A self-directed IRA custodian that already offers Gold or Silver IRAs can typically also purchase IRS-eligible platinum or palladium bullion for the same account, held at the same approved depository, subject to the same overall IRA contribution limits ($7,500 for 2026, $8,600 if you’re 50 or older) or rollover rules as any other precious-metals IRA purchase. Ask specifically — it’s usually not the default product shown on a company’s website.
Frequently Asked Questions
Can I hold platinum or palladium in the same IRA as my gold?
Yes. IRC 408(m)(3) allows a mix of IRA-eligible gold, silver, platinum, and palladium in a single self-directed precious-metals IRA, as long as each item independently meets its own purity requirement.
Is platinum or palladium a better inflation hedge than gold?
There’s no settled answer — both have a real industrial-demand component that gold largely lacks, which means their prices can diverge from gold’s during industrial slowdowns or booms. That’s a different risk/return profile, not automatically a better or worse one.
Do platinum and palladium get the same tax treatment as gold or silver in an IRA?
Yes. Inside an IRA, all IRS-eligible bullion metals follow the same account-level tax rules (ordinary income on traditional withdrawals, tax-free on qualified Roth withdrawals) — the collectibles capital-gains rate only applies to personally-held (non-IRA) physical metal.
