Gold IRA Eligible Metals: IRS Purity Requirements

Not every gold coin or silver bar belongs in a retirement account. The IRS maintains strict rules about which gold IRA eligible metals qualify, and the consequences of holding the wrong ones range from disqualification of your entire IRA to a 10% early withdrawal penalty plus ordinary income tax on the full account value.

The problem? Most guides give you a vague list of “approved coins” without ever showing you the actual law. That changes here. We’re going to walk through IRC Section 408(m)(3)(B) clause by clause, explain exactly what it means in plain English, and then cover the metals people commonly get wrong.

IRC Section 408(m)(3)(B): What the Law Actually Says

The IRS doesn’t publish a simple list of “approved Gold IRA metals.” Instead, it defines eligibility through a set of purity requirements and exceptions embedded in the Internal Revenue Code.

Here’s the relevant statute, broken into its operative clauses:

Clause 1, The general rule (408(m)(3)(A)): Precious metals held in an IRA are treated as “collectibles,” and acquiring a collectible with IRA funds triggers an immediate taxable distribution. In other words, the default position is that you cannot hold physical metals in an IRA.

Clause 2, The exception (408(m)(3)(B)): The collectibles rule does not apply to certain coins and bullion that meet specific fineness standards, provided the physical metal is held by a bank, approved non-bank trustee, or an IRS-approved depository.

Clause 3, The fineness standards: Gold must meet 0.9995 fineness (99.95% pure). Silver must meet 0.999 fineness (99.9% pure). Platinum and palladium must each meet 0.9995 fineness.

Clause 4, The American Eagle exception (408(m)(3)(A)(ii)): Gold, silver, and platinum American Eagle coins are explicitly exempt from the fineness requirement. This is a named carve-out, Eagles are eligible by statute regardless of their actual purity.

This last clause is the one that confuses people most, and we’ll break it down in its own section below.

Purity Requirements by Metal: The Complete Table

The IRS doesn’t care about the brand on a coin or which mint struck it. What matters is whether the metal itself meets the fineness threshold defined in IRC Section 408(m)(3)(B).

Metal	IRS Minimum Fineness	Percentage Equivalent	Common Measure	Added to IRC
Gold	0.9995	99.95%	24 karat (effectively)	1986 (TRA)
Silver	0.999	99.9%	.999 fine	1986 (TRA)
Platinum	0.9995	99.95%	.9995 fine	1986 (TRA)
Palladium	0.9995	99.95%	.9995 fine	1997 (TRA ‘97)

A few things to notice in this table.

Gold’s requirement of 0.9995 fineness is stricter than most people realize. Standard 22-karat gold (91.67% pure) fails this test. That means most gold jewelry, many historic coins, and even some well-known bullion coins do not qualify.

Silver’s threshold is slightly more lenient at 0.999, but this still eliminates all pre-1965 U.S. silver coins (which are only 90% silver) and most sterling silver products (92.5%).

Palladium was added to the eligible metals list by the Taxpayer Relief Act of 1997. Before that, your IRA could hold gold, silver, and platinum, but not palladium. This matters because palladium has a fundamentally different supply profile than the other three metals, more on that below.

Approved Products: What Actually Passes the Test

Meeting the fineness threshold is necessary but not sufficient. The metal must also be produced by a national government mint or a refiner/assayer accredited by NYMEX, COMEX, or the London Bullion Market Association (LBMA). Here’s what makes the cut:

Gold (0.9995 Fineness)

• American Gold Eagle (1 oz, 1/2 oz, 1/4 oz, 1/10 oz), eligible by statutory exception, despite being 22-karat
• American Gold Buffalo (1 oz), 24-karat, meets fineness on its own merits
• Canadian Gold Maple Leaf (1 oz, fractional sizes)
• Austrian Gold Philharmonic (1 oz)
• Australian Gold Kangaroo/Nugget (1 oz)
• PAMP Suisse, Credit Suisse, and other LBMA-accredited gold bars (must be 0.9995+ fine)

Silver (0.999 Fineness)

• American Silver Eagle (1 oz), eligible by statutory exception
• Canadian Silver Maple Leaf (1 oz)
• Austrian Silver Philharmonic (1 oz)
• Australian Silver Kookaburra / Koala (1 oz)
• LBMA-accredited silver bars (100 oz, 1000 oz) meeting 0.999 fineness

Platinum (0.9995 Fineness)

• American Platinum Eagle (1 oz, fractional), eligible by statutory exception
• Canadian Platinum Maple Leaf
• Australian Platinum Koala
• Isle of Man Noble (1 oz)
• LBMA-accredited platinum bars

Palladium (0.9995 Fineness)

• Canadian Palladium Maple Leaf (1 oz)
• LBMA-accredited palladium bars

Palladium has the thinnest product selection of any eligible metal. There is no American Palladium Eagle program, and only a handful of sovereign mints produce palladium coins at the required fineness. If you’re considering palladium for your precious metals IRA, the Canadian Maple Leaf is essentially your only coin option.

Why Palladium Was Added in 1997, And Why That Matters Now

When Congress passed the Taxpayer Relief Act of 1997, it added palladium to the list of IRA-eligible metals. At the time, palladium traded around $200/oz and was a niche industrial metal.

Today, palladium trades at multiples of that price, driven almost entirely by catalytic converter demand. Over 80% of global palladium consumption comes from the auto industry. Russia and South Africa produce over 75% of the world’s supply.

This creates a fundamentally different risk profile than gold or silver. Gold’s value is driven by monetary demand, central bank buying, and safe-haven flows. Palladium’s value is driven by emissions regulations and auto manufacturing output. If electric vehicles continue displacing internal combustion engines, palladium demand faces structural headwinds that don’t affect gold.

For IRA holders weighing palladium, the question isn’t just “is it eligible?” but “does its demand profile fit a retirement timeline?” If you’re 55 and planning to take distributions at 73 (under the SECURE 2.0 Act RMD rules for those born between 1951-1959), that’s an 18-year window during which the automotive industry could shift substantially toward EVs.

The Metals People Get Wrong: A Disqualified List

This is where costly mistakes happen. The following metals are commonly assumed to be IRA-eligible but are not:

South African Krugerrand

The Krugerrand is the world’s most widely traded gold coin. It is 22-karat (91.67% pure) and contains exactly 1 troy ounce of gold, but it achieves this by weighing more than 1 oz total (the balance is copper alloy). Its fineness of 0.9167 falls well below the 0.9995 threshold. Unlike the American Eagle, the Krugerrand has no statutory exception in IRC 408(m).

Pre-1933 U.S. Gold Coins

Liberty Head Double Eagles, Saint-Gaudens $20 pieces, Indian Head Eagles, these are 90% gold (0.900 fineness). They fail the purity test. They’re also classified as numismatic (collector) coins, which the IRS explicitly treats as collectibles under 408(m)(2). Some dealers aggressively market pre-1933 coins for IRAs. They’re wrong, and holding them in your IRA would trigger a deemed distribution.

British Gold Sovereigns

Sovereigns are 22-karat (0.9167 fineness). Same problem as the Krugerrand, no statutory exception, doesn’t meet the purity threshold.

Chinese Gold Panda

Chinese Pandas are 0.999 fine (99.9% pure), which sounds high but falls short of the 0.9995 requirement for gold. This is the most counterintuitive exclusion on the list, a 99.9% pure gold coin that doesn’t qualify because the threshold is 99.95%.

Fractional Collectible Coins

Any gold coin marketed primarily for its rarity, historical significance, or numismatic premium is likely classified as a collectible regardless of purity. The IRS looks at the nature of the asset, not just the metal content.

90% “Junk” Silver Coins

Pre-1965 U.S. dimes, quarters, and half dollars are 90% silver. The IRS requires 99.9%. These are popular with stackers but cannot be held in an IRA.

If you’re working with a reputable Gold IRA company like Augusta Precious Metals or Noble Gold, they should steer you away from ineligible metals automatically. If a dealer encourages you to put Krugerrands or pre-1933 coins in your IRA, that’s a red flag.

The American Eagle Exception: Why 22-Karat Coins Get a Pass

American Gold Eagles are only 22-karat, 91.67% pure gold, with silver and copper alloy making up the rest. By the fineness test alone, they’d be disqualified. But Congress carved out a specific exception in IRC Section 408(m)(3)(A)(ii).

The exception names American Eagle coins explicitly. It covers Gold Eagles, Silver Eagles, and Platinum Eagles. This is a political choice, not a metallurgical one, Congress wanted American-minted coins to be available for IRAs regardless of their alloy composition.

This exception applies only to American Eagles. It does not extend to:

• American Gold Buffalo coins (which qualify anyway because they’re 24-karat)
• Any foreign 22-karat coin
• Any other U.S. Mint commemorative or proof coin not named in the statute

The practical implication: if a dealer tells you a particular coin is “IRA-eligible because it’s just like an Eagle,” demand they show you the specific IRC provision. If they can’t, walk away.

McNulty v. Commissioner: The Home Storage Warning

In 2023, the Tax Court ruled in McNulty v. Commissioner that a taxpayer who set up a “home storage Gold IRA” through a self-directed LLC structure owed taxes and penalties on the full value of the metals. The IRS treated the acquisition of physical gold held at the taxpayer’s home as a taxable distribution.

This case is relevant to eligible metals for a specific reason: even if your metals meet every purity and product requirement, where they’re stored determines whether the IRA treatment survives. IRC 408(m)(3)(B) requires that bullion be held by “a bank (as defined in [IRC] section 408(n))” or by “a person” who meets the trustee requirements.

Your house is not a bank. Your safe is not an IRS-approved depository.

The McNulty ruling didn’t break new legal ground, it confirmed what tax professionals had warned about for years. But it established clear precedent that home-storage IRA schemes will be treated as distributions, triggering income tax plus the 10% early withdrawal penalty for those under 59½.

If you’re under 50, that penalty applies on top of ordinary income tax. For a $100,000 Gold IRA, a deemed distribution could mean $30,000-$40,000 in combined federal taxes and penalties.

Decision Matrix: Comparing Eligible Metals for Your IRA

Choosing which eligible metals to hold isn’t just about purity. Here’s how the four metals stack up on factors that affect your IRA’s actual returns:

Factor	Gold	Silver	Platinum	Palladium
Premium Over Spot	3-5% (bars), 5-8% (coins)	8-15% (coins), 3-5% (bars)	5-10% (coins)	8-15% (coins)
Buyback Spread	1-3%	3-5%	3-7%	5-10%
Storage Cost Impact	Low (high value density)	High (bulky per dollar)	Low	Low
Liquidity at Distribution	Highest, instant market	Good, wide market	Moderate, thinner market	Lowest, fewer buyers
RMD Complexity	Low, easy to value/sell	Moderate, more units to manage	Moderate	High, volatile pricing

The “buyback spread” column deserves attention. When you take a required minimum distribution (beginning at age 73 or 75 depending on your birth year under SECURE 2.0), your custodian sells metals on your behalf. The spread between what they pay you and the spot price is an invisible fee.

Gold typically has the tightest spreads because the market is deepest. Palladium has the widest because fewer dealers make active markets. Over a 20-year accumulation phase, choosing high-spread metals can cost you thousands at distribution time.

If you’re building a precious metals IRA with the standard 2026 contribution limit of $7,500 per year ($8,600 if you’re 50 or older), the premium-over-spot percentage has an outsized impact on small annual purchases. At 5% premium on gold, you’re paying $375 per year above metal value. At 12% premium on silver coins, that’s $900. Over a decade, those premiums compound into meaningful drag on returns.

Storage and Custodian Requirements for Eligible Metals

Even perfectly eligible metals become taxable distributions if stored improperly. The IRS requires:

1. A qualified trustee or custodian, typically a bank, credit union, or IRS-approved non-bank trustee
2. An approved depository, facilities like Delaware Depository, Brink’s, or International Depository Services
3. Segregated or commingled storage, both are permitted, but segregated (your metals stored separately) costs more and some investors prefer it for peace of mind

Your custodian is legally responsible for reporting the IRA’s value to the IRS annually. They need to be able to verify and value the metals, which is another reason the IRS restricts eligible products to standardized, easily valued items from recognized mints and refiners.

Frequently Asked Questions

Are South African Krugerrands eligible for a Gold IRA?

No. Krugerrands are 22-karat gold (91.67% purity), which falls below the IRS requirement of 0.9995 fineness. Unlike American Gold Eagles, Krugerrands do not have a statutory exception in IRC Section 408(m). Holding Krugerrands in your IRA would be treated as a taxable distribution.

Why are American Gold Eagles eligible if they’re only 22-karat?

Congress created a specific exception in IRC Section 408(m)(3)(A)(ii) for American Eagle coins. This exception is written into the statute by name, it applies only to American Eagles (gold, silver, and platinum), not to any other 22-karat coin. The Gold Buffalo, by contrast, qualifies on its own merits because it’s 24-karat.

Can I store Gold IRA metals at home in a safe?

No. The Tax Court confirmed in McNulty v. Commissioner (2023) that home storage of IRA metals constitutes a taxable distribution. The IRS requires that eligible metals be held by a qualified trustee at an approved depository. Violating this rule triggers income tax on the full value plus a 10% early withdrawal penalty if you’re under 59½.

What happens if I accidentally hold ineligible metals in my IRA?

The IRS treats the purchase of ineligible metals (collectibles) with IRA funds as a deemed distribution under IRC 408(m)(1). You’ll owe ordinary income tax on the value of the metals, plus a 10% early withdrawal penalty if you’re under 59½. The penalty alone on a $50,000 position would be $5,000, on top of your marginal tax rate applied to the full amount.

Is palladium a good choice for a Gold IRA?

Palladium is IRA-eligible at 0.9995 fineness, but it carries unique risks. Over 80% of palladium demand comes from automotive catalytic converters, making it highly sensitive to auto industry trends and the EV transition. It also has the widest buyback spreads and fewest product options of any eligible metal. Most financial advisors suggest it as a small satellite position rather than a core IRA holding.
