What Is a Gold IRA? Rules, Custodians, and Eligible Metals
A Gold IRA is not a special type of retirement account -- it is a standard Individual Retirement Account, structured as a self-directed IRA, that holds physical precious metals instead of (or alongside) stocks, bonds, and mutual funds. The tax treatment is the same as any other traditional or Roth IRA; what changes is what the account is allowed to hold and how that holding has to be stored.
This article is general information, not investment or tax advice. Rules governing retirement accounts change and depend on individual circumstances -- consult a qualified financial advisor or tax professional before opening or funding a precious metals IRA.
Not every coin or bar qualifies
Because a Gold IRA holds real, physical metal inside a tax-advantaged account, the IRS restricts what can go in it under Internal Revenue Code Section 408(m). Only bullion meeting specific minimum purity (fineness) standards is eligible:
| Metal | Minimum purity (fineness) |
|---|---|
| Gold | 99.5% (.995 fine) |
| Silver | 99.9% (.999 fine) |
| Platinum | 99.95% (.9995 fine) |
| Palladium | 99.95% (.9995 fine) |
These thresholds exist to keep the account holding investment-grade bullion rather than collectible or numismatic items, whose value depends on rarity and condition rather than metal content.
The American Gold Eagle exception
There is one well-known exception to the gold purity rule: the American Gold Eagle coin, struck at 22-karat (91.67% pure) rather than .995 fine. Because it is issued directly by the U.S. Mint, Congress specifically wrote it into the eligible-metals list, and it remains one of the most commonly held coins in Gold IRAs despite not meeting the general purity threshold that applies to every other gold product.
Why a custodian and an approved depository are required
A Gold IRA cannot be self-stored. IRS rules require the account to be administered by a self-directed IRA custodian -- a bank, trust company, or other IRS-approved institution -- and the physical metal itself must sit in an IRS-approved depository, not a home safe or personal deposit box. This structure exists to keep the assets clearly separated from the account holder's personal property, which is part of what preserves the account's tax-advantaged status. Attempting to take physical possession of IRA-held metal yourself is generally treated as a taxable distribution.
In practice, opening a Gold IRA means working with three parties: a custodian who administers the account and reports to the IRS, a metals dealer who sources IRS-eligible coins or bars, and a depository that stores them securely on the account's behalf.
Funding a Gold IRA
Most Gold IRAs are funded one of two ways: a direct contribution (subject to the same annual IRA contribution limits as any other IRA) or a rollover from an existing 401(k), traditional IRA, or similar retirement account. A properly executed custodian-to-custodian rollover avoids triggering taxes or early-withdrawal penalties; a rollover handled incorrectly -- for example, taking a distribution personally before redepositing it -- can trigger both.
Why investors consider it
The core appeal is diversification: physical metal inside a Gold IRA moves independently of stock and bond markets, and some investors use it as a hedge against inflation or currency devaluation. It comes with trade-offs worth weighing against that appeal -- custodian and storage fees that a standard brokerage IRA doesn't carry, and less liquidity than selling shares of a fund. Whether that trade-off makes sense depends on an individual's broader retirement strategy, which is exactly the kind of decision a financial advisor is positioned to help with.
