What "IRA-eligible" means for a bar

The phrase "IRA-eligible gold bar" is not a marketing term. It is a legal outcome under Internal Revenue Code Section 408(m). Paragraph (m) generally bans collectibles inside an IRA. Paragraph (m)(3) then carves out a narrow class of high-grade bullion the account is allowed to hold.

For bars specifically, the relevant carve-out is IRC 408(m)(3)(B). It permits gold, silver, platinum, and palladium bullion that meets or exceeds the minimum fineness required for a commodity contract deliverable under a US commodity contract market. For gold that floor is 99.5 percent purity.

The same paragraph adds a custody condition. The bullion must be in the physical possession of a bank or an IRS-approved non-bank trustee under Section 408(a). A retail investor cannot store the bar at home, in a personal safe, or in a bank safe deposit box under the IRA's name. Personal possession triggers a distribution.

Sitting behind the statutory text is an industry filter that decides which bars actually get onto custodian approval lists. The refiner or mint that stamped the bar must be recognized. The next two sections cover the fineness threshold and the refiner rule in detail.

The 99.5 percent fineness floor

The 99.5 percent minimum is not an arbitrary number. It matches the COMEX gold futures delivery specification managed by CME Group. IRC 408(m)(3)(B) references the commodity contract market delivery standard directly, so the IRS floor moves with COMEX rather than with any IRS-invented threshold.

Most modern refiner bars are struck at 99.99 percent (the industry shorthand is "four nines"). PAMP Suisse, Valcambi, Argor-Heraeus, Perth Mint, Royal Canadian Mint, Rand Refinery, and Asahi Refining USA all publish four-nines gold bar product lines. Each of those bars sits comfortably above the IRA floor.

The London Good Delivery bar is the only mainstream product that sometimes runs at the minimum. A 400 troy ounce Good Delivery bar must be a minimum of 99.5 percent fine, though many refiners deliver higher. That still clears the IRA test, but the bar has to come from an LBMA-accredited refiner for a custodian to book it.

The fineness rule applies to the bar itself, not to the plastic assay card or shrink wrap it ships in. A four-nines bar packaged with a marketing pamphlet is still four nines. What matters is what the refiner stamped on the bar and what the assay certificate documents.

The refiner accreditation rule

The IRC does not name specific refiners. Custodians and depositories fill that gap by keeping an approved-brand list. In practice, four accreditation routes qualify a refiner to have its bars accepted by a self-directed IRA custodian.

Most self-directed IRA custodians reduce this to a plain-language rule of thumb. If the refiner name is on the LBMA Good Delivery gold list or the CME COMEX approved brand list, the bar clears the accreditation test. Everything else needs specific written confirmation from the custodian before the account releases cash.

Common IRA-accepted bar brands

The list below covers the refiners most commonly seen on custodian approval sheets for gold bars in 2026. It is not exhaustive; the LBMA Good Delivery gold list currently includes several dozen refiners across roughly a dozen countries.

Sunshine Minting, Ohio Precious Metals, and the two US-based Asahi and Metalor operations matter to Texas investors for one reason. They allow a buyer to source domestically refined gold that a custodian can book without extra paperwork. Domestic refining is not a legal requirement, only a convenience.

Bar sizes typically accepted

Bar size does not decide IRA eligibility. Fineness plus refiner does. That said, custodians and dealers each maintain internal price sheets and product lists, so certain sizes dominate what actually shows up in an IRA account.

Kilogram and 10 ounce bars tend to be the most storage-efficient size for a mid-sized IRA. A 100,000 dollar allocation at recent spot maps roughly to two to three kilogram bars, avoiding the premium stack that comes with a stack of one-gram or one-ounce pieces.

Silver, platinum, palladium bars: parallel rules

Path B of IRC 408(m)(3) covers all four IRA-eligible precious metals. Each metal carries its own fineness floor, borrowed from the corresponding commodity contract market delivery standard. The refiner accreditation rule applies the same way across metals.

Custodians will accept mixed-metal IRAs. A Texas resident can hold a kilogram gold bar from Argor-Heraeus alongside a 100 ounce silver bar from Sunshine Minting inside the same self-directed IRA. Storage at the same depository is standard; segregated storage keeps each bar identified to the owner.

How to verify a bar is IRA-eligible

Before a self-directed IRA custodian releases cash to buy any bar, someone has to confirm the bar clears IRC 408(m)(3)(B). Most dealers do this by reference to a preset product list. The check runs the same way whether you use a dealer product list or verify it yourself.

1. Identify the refiner or mint stamped on the bar. Every accepted bar carries a refiner mark, brand logo, or mint stamp. If the bar carries no clear refiner identification, it does not enter an IRA regardless of purity claims on the packaging.
2. Confirm the refiner is on the LBMA Good Delivery gold list or a CME COMEX approved brand list. LBMA publishes the current gold refiner list at lbma.org.uk. CME COMEX approved brands live in the exchange's rulebook.
3. Verify the stamped fineness. The bar must read 999.5, 0.9995, 999.9, or 999.99 for gold; the last three exceed the IRA floor. A 995 or 999 stamp meets the minimum. Foreign fineness marks such as 24K carat notation are not enough by themselves.
4. Check the assay card or certificate. Fabricated bars in the 1 gram to 100 gram range usually ship in tamper-evident assay cards. Cast bars 10 ounces and larger typically ship with a paper assay certificate that lists refiner, serial number, weight, and fineness.
5. Match the bar to the custodian's product list. Ask your self-directed IRA custodian for its accepted bullion list in writing. If the refiner and the bar size are on the list, the metal can enter the IRA. If not, do not order.
6. Order through the IRA and ship dealer-to-depository. The custodian pays the dealer directly from IRA cash. The dealer ships the bar to an IRS-approved depository, never to your address. The metal must stay at the depository to preserve IRA status.

Assay cards, serial numbers, and chain of custody

An assay card is not decorative packaging. It is the audit trail that a specific bar came off a specific refiner's production run and passed the refiner's quality control. Depositories log the serial number at intake. Custodians book the serial number to the IRA account. Sending the bar as-shipped, sealed in its assay card, keeps that chain intact.

Opening the assay card breaks the seal and can trigger a re-assay requirement when the bar is later sold or delivered. A re-assay slows a buyback and can cost tens of dollars per bar. For a Texas investor planning to hold the bar for a decade or more, the practical rule is simple: never open the assay card until the bar is being sold or delivered out.

Serial numbers matter at withdrawal. If the account owner takes an in-kind distribution at retirement, the depository ships the same serial-numbered bar to the owner. In a segregated storage arrangement, the owner receives the specific bar deposited, not a pool-share equivalent. This is different from unallocated storage, where the account owns a fractional claim on a pool rather than a specific bar.

Storing bars in Texas at the state depository

Texas residents have an in-state option most other states do not. The Texas Bullion Depository sits in Leander, north of Austin. It is an agency of the State of Texas, authorized by House Bill 483 signed by Governor Greg Abbott on June 12, 2015, and in operation since 2017.

The depository is operated under state contract by Lone Star Tangible Assets LP. Storage covers gold, silver, platinum, palladium, and rhodium. Segregated storage is the standard, meaning the exact bar you deposited comes back at withdrawal.

For IRA use, IRC Section 408(a)(2) requires the metal to be held by a bank or an IRS-approved non-bank trustee. Lone Star Tangible Assets received IRS approval as a non-bank trustee in 2023. That approval, plus a partnership with Equity Trust Company as the self-directed IRA custodian, opens the depository to IRA-held metal.

Insurance at the depository is placed with Lloyd's of London and covers theft, fire, flood, and natural disasters at daily market value. The vault carries a Class 3 UL rating with bullet-resistant doors, biometric access, and on-site security personnel. State-agency oversight adds a Comptroller audit layer that private depositories cannot match.

The workflow for a Texas resident maps to the same six steps as any other state. Open a self-directed IRA with a qualified custodian. Fund it. Place a buy direction with the dealer. The dealer ships the bar to the depository. The depository confirms receipt. The custodian books the bar to the IRA. What differs is that the metal never leaves Texas.

At distribution time, Article 8, Section 24 of the Texas Constitution bans a state personal income tax. Required minimum distributions at age 73 or 75, Roth conversions, and early withdrawals face federal tax only. The federal 10 percent early-withdrawal penalty still applies before age 59.5, but no Texas state tax layer stacks on top.

Fee drag on a bar-only IRA

Fineness and refiner rules decide what can enter the IRA. Fees decide how much of the growth actually stays. The calculator below models the compounded drag from custodian, storage, and administration charges over the holding period.

The tool is a planning model, not personalized advice. It does not include the one-time dealer markup on the bar purchase itself, which is a separate line from the recurring fees the tool captures.
